SpaceX employees worked grueling hours and gritty conditions in the company's early days.
Elon Musk offered workers SpaceX stock options to poach top talent and keep them motivated.
One expert said that for stocks to work, companies have to give employees chances to cash in.
Working at SpaceX in the company's earliest days was intense, but it may pay off for some hires.
Tough working conditions might tank some businesses, but not SpaceX. On December 11, Bloomberg reported that the Elon Musk-founded company was valued at $350 billion, making it the most valuable private startup worldwide.
The value comes after SpaceX and some of its approved investors struck a deal to buy up to $1.25 billion of employees' shares, offering $185 a share. Therein lies a partial key to SpaceX's overwhelming success.
Like many tech startups, SpaceX offered its early employees stock options as a financial incentive to keep them invested in the company's success β even when they were exposed to Musk's strict standards, his bouts of shouting when things went wrong, and his near-impossible timelines, space journalist Eric Berger reported.
In his new book "Reentry," Berger shares current and former employees' accounts of working 36-hour days, sleeping under their desks, urinating in buckets, dodging rattlesnakes, and injuring themselves on the job.
Stock options are a toss-up. They don't always end up being valuable. SpaceX was proving its value early, though.
"Even as far back as 2010, you could see that that had real value if you stayed there," Berger told Business Insider.
How equity pushes employees
Offering stock options is a common strategy, especially for early-stage companies that don't have much cash for salaries, said Jorge Martin, head of the employee-equity plan provider North American branch of JP Morgan Workplace Solutions.
"When they are working these grinding hours, when they are traveling all over the world, when they're under high pressure," Martin said, "then all of that is worth it when you have an equity grant that can grow as the company grows and as the company succeeds."
Martin said he's occasionally seen startup employees become millionaires off their equity.
The promise of those stock options gave SpaceX a competitive edge in recruiting top engineering talent. In the scramble for new hires fresh out of college in the 2010s, SpaceX, Berger said, often competed with Blue Origin, a similarly ambitious rocket company founded by Jeff Bezos.
"They would poach people back and forth," Berger said.
Cashing in on company equity
Workers can turn shares into cash when a company gets sold or goes public β which SpaceX has not done β or when it does a "tender offer," allowing employees to sell their shares to other investors.
Blue Origin has a stock ownership program too, Berger said, but it's "considered virtually worthless because Bezos is probably never going to sell a significant chunk of the company. So those shares can never really be sold."
SpaceX, meanwhile, has given its employees multiple opportunities to cash in on their shares, including through the deal it struck this month.
Musk's Mars vision helped
SpaceX offered some of its early employees more than stock. Some truly believed in Musk's plans to build a human settlement on Mars.
Unlike a regimented job at NASA or a legacy aerospace corporation, a gig at SpaceX meant working hands-on with multiple ambitious rockets, spaceships, or engines βΒ back to back or simultaneously.
Some scientists trying to create "mirror life" have stopped in their tracks.
A mirror microorganism could end up being a major pathogen since our immune systems wouldn't notice it.
Mirror-image biology inverts a fundamental property of life on Earth: which way molecules point.
Creating "mirror life" could be one of science's greatest breakthroughs, but some researchers who began the effort are now calling for it to stop.
No mirror-life microorganisms exist yet. However, 38 scientists warned in a paper published in the journal Science on December 12 that if someone created one and it escaped the lab, it could cause a catastrophic multi-species pandemic.
"We're basically giving instructions of how to make a perfect bioweapon," Kate Adamala, a co-author of the paper and a chemist who leads a synthetic biology lab at the University of Minnesota, told Business Insider.
As the risks became clear, Adamala ended her lab's efforts toward building a mirror cell. Her multi-year grant for that facet of their research expired and she decided not to apply for renewal, she said.
Now she's urging other scientists to do the same, along with the 37 other researchers.
"Although we were initially skeptical that mirror bacteria could pose major risks, we have become deeply concerned," they wrote in the paper.
What is mirror life?
Mirror biology takes a fundamental rule of life on Earth, called chirality, and flips it.
Chirality is the simple fact that molecules β like sugars and amino acids β point in one of two directions. They are either right-handed or left-handed.
For some reason, though, life will only use one chiral form of each molecule. DNA, for example, only uses right-handed sugars for its backbone. That's why it twists to the right.
In mirror biology, scientists aim to create living cells where all the chirality is flipped. Where natural life uses a right-handed peptide, to build proteins, mirror life would use the same peptide in its left-handed form.
Adamala's research was focused on making mirror peptides, which can help create longer-lasting pharmaceuticals.
A full mirror cell was the long-term goal of that research. Mirror cells could help prevent contamination in bioreactors that use bacteria for green chemical manufacturing because, in theory, they wouldn't interact with natural microorganisms.
"You could have this perfect bioreactor that can just sit there and you can stick your finger into it and you're not going to contaminate it," Adamala said. "That's also precisely the problem."
A mirror bacteria could bypass the natural checks and balances of life, like competing with other bacteria or battling our immune systems.
Immune systems would ignore mirror cells
Adamala said "the death sentence" for her mirror-cell research came when she spoke to immunologists. They explained that for humans, other animals, and plants, immune system activation depends on chirality.
Immune cells recognize pathogens' proteins, but they wouldn't detect the inverse versions of those proteins that mirror cells would use.
A mirror pathogen "doesn't interact with the host. It just uses it as a warm incubator with a lot of nutrients," Adamala said.
If a mirror bacteria escaped the lab, it could cause slow, persistent infections that can't be treated with antibiotics (because those, too, rely on chirality).
Because they wouldn't face any immune resistance, mirror bacteria wouldn't need to specialize in infecting corn, or goats, or birds.
"It would be a disease of anything that lives that can be infected," Adamala said.
In the worst-case scenario, a mirror bacteria would multiply endlessly, unfettered. It would take over its hosts and eventually kill them. It would destroy crops. It would have no predators. It would overwhelm entire ecosystems, swapping out portions of our natural world for a new mirror world.
A long way away
Ting Zhu, one of the leading researchers trying to make a mirror cell, told BI in an email that he supports being cautious but doesn't think "a complete mirror-image bacterium can be synthesized in the foreseeable future."
Zhu leads a mirror-image biology lab at Westlake University in China. He was not involved in the Science paper.
Adamala estimates that the world's first mirror bacteria is still about a decade away. She argues that's exactly why the research should stop now before it builds all the tools that someone could use to make that final leap.
"No one can do it on their own right now," Adamala said. "The technology is not mature enough, which means we're pretty well safeguarded against someone crazy enough to say, 'I'll just go do it.'"
In the meantime, Adamala and the other paper authors invited more research and scrutiny on the risks they've identified.
"If someone does prove us wrong, that would make me really happy," she said.
A bird flu outbreak has ravaged the world's birds since 2020 and infected cattle earlier this year.
California Gov. Gavin Newsom declared a state of emergency over the virus this week.
Health officials also confirmed the first "severe" case of and hospitalization for the H5N1 virus.
The burgeoning global bird flu outbreak continued its flight path across the country this week, with two major developments that point to the virus's increasingly concerning spread.
California Gov. Gavin Newsom declared a state of emergency over the virus on Wednesday, citing a worrying number of infected herds throughout the state in recent months and a need for more resources.
Since the state first identified the H5N1 avian influenza virus in cattle in late August, California's agriculture department has confirmed 645 infected dairy herds.
Newsom's announcement, meanwhile, came just hours after health officials confirmed the first severe case of bird flu in Louisiana, saying a person was hospitalized with an infection after being exposed to sick birds in his backyard.
In recent months, infectious disease experts have grown more and more nervous about the possibility of a human pandemic linked to the virus, even as the Centers for Disease Control and Prevention has maintained that the public health risk for humans is low.
Here's where things stand.
Bird flu outbreak
The H5N1 virus first reemerged in Europe in 2020 and has since become widespread in birds around the world. The outbreak has killed tens of millions of birds and tens of thousands of sea lions and seals in recent years.
Birds carry the disease while migrating and can expose domestic poultry to the virus while never showing signs themselves, according to the CDC.
The virus jumped to cattle herds for the first time ever earlier this year in a major escalation. Then, in October, a pig in Oregon tested positive for the virus, an especially concerning case as swine can host both bird and human flu viruses.
There has been no known human-to-human transmission yet. Still, the growing pattern of mammal-to-mammal transmission has infectious disease experts on guard against the possibility that H5N1 could eventually become a human pandemic.
"If it keeps spreading in animals, then it is eventually going to cause problems for humans, either because we don't have food because they've got to start exterminating flocks, or because it starts to make a jump in humans," Dr. Jerome Adams, a former surgeon general and the director of health equity at Purdue University, told Business Insider in April.
"The more it replicates, the more chances it has to mutate," he added.
The ongoing multi-state dairy cattle outbreak, which is believed to have started in Texas, has infected 865 herds across 16 states, according to the CDC, and has led to a growing number of human cases among US dairy and poultry workers.
The CDC has thus far confirmed 61 reported human cases and seven probable cases across the US, though some scientists estimate that the real number of infections is higher.
More than half of the human cases are tied to interaction with sick cattle. The remaining infections have been traced to exposure to sick poultry or have an unknown origin, the CDC said.
State of emergency
California's Wednesday announcement will give state and local authorities increased resources to study and contain the outbreak, Newsom said.
"This proclamation is a targeted action to ensure government agencies have the resources and flexibility they need to respond quickly to this outbreak," the governor said in a statement.
Earlier this month, the Agriculture Department said it would start testing the nation's milk supply for traces of the virus, requiring dairy farmers to provide raw milk samples upon request. Up until then, cattle testing for potential infections had been almost entirely voluntary.
Dr. Monica Gandhi, a professor of medicine and associate chief of the Division of HIV, Infectious Diseases, and Global Medicine at the University of California, San Francisco, said the declaration will likely give California a greater ability to surveil dairy farms for signs of the virus.
But declaring a state of emergency could be a double-edged sword.
Phrases "like 'state of emergency,' given that we've just been through a pandemic, can induce panic," Gandhi said.
And it's not time to panic yet, she said.
Gandhi praised the CDC's "very measured" messaging around the virus thus far and said health officials are closely monitoring the spread.
Now, their return is being delayed another month to give SpaceX time to process a new spaceship.
NASA and SpaceX are using the new ship, instead of a refurbished one, to expand SpaceX's fleet.
Two astronauts have been stuck on the International Space Station for months because of issues with Boeing's new Starliner spaceship.
Now, they'll have to stay just a bit longer because SpaceX needs extra time to prepare itsCrew Dragon spaceship.
Butch Wilmore and Suni Williams were set to finally come back to Earth in February. Now the earliest they can return is in late March, NASA announced in a blog post on Wednesday.
While one month is not a terribly long delay by regular NASA mission standards, the extra time in orbit is significant considering Wilmore and Williams launched into space for a roughly eight-day mission way back in June.
SpaceX needs extra time to process a new spaceship
SpaceX's Crew-10 mission, originally scheduled for February, is supposed to relieve Wilmore and Williams and allow them to finally return home.
NASA and SpaceX recently decided, though, to use a new Dragon spaceship rather than a used, refurbished one for that launch, according to NASA's blog post.
The new spaceship will need extra time after it ships to SpaceX's processing facility in Florida in January. That's why NASA pushed back the launch date.
"Fabrication, assembly, testing, and final integration of a new spacecraft is a painstaking endeavor that requires great attention to detail," Steve Stich, the manager of NASA's Commercial Crew Program, said in a statement.
This was "the best option for meeting NASA's requirements and achieving space station objectives for 2025," the blog post said.
SpaceX has reused Dragon spaceships for NASA missions in the past. However, a NASA spokesperson told BI that certifying the new spacecraft will expand the company's Crew Dragon fleet to five human-rated spaceships, for both NASA and private missions.
In a statement sent in an email, the spokesperson said that Wilmore, Williams, and their crewmate Nick Hague were "supportive of the path forward."
They added that the three astronauts "understood the possibilities and unknowns, including being aboard station longer than planned."
SpaceX did not immediately respond to a request for comment.
SpaceX to the rescue
The question of how Wilmore and Williams would get back to Earth arose soon after their launch.
As their newly-minted Boeing Starliner ship approached the ISS in early June, it experienced engine issues that raised NASA officials' eyebrows.
After weeks of testing and deliberating, NASA decided to send the Starliner back to Earth empty. Officials weren't confident enough that it was safe.
Meanwhile, Wilmore and Williams stayed on the space station. NASA reassigned them to its next mission with SpaceX, called Crew-9. They would have a ride home on that spaceship. Two other astronauts gave up their SpaceX seats to make room for the Boeing duo.
The catch was that Wilmore and Williams would have to serve the same six-month shift as the rest of Crew-9. They've been conducting experiments and maintenance on the ISS just like everyone else, with the promise of coming home in February.
Now, they'll have to wait another month.
"We appreciate the hard work by the SpaceX team to expand the Dragon fleet in support of our missions," Stich said in the Wednesday statement, adding his appreciation for "the flexibility of the station program and expedition crews."
Gov. Gavin Newsom of California declared a "proactive" state of emergency over the H5N1 bird flu.
The virus has spread rapidly through US dairy cattle herds, with 16 states affected.
The CDC reports low public risk with no human-to-human spread, but 61 human cases have been detected.
Gov. Gavin Newsom of California declared a state of emergency over the H5N1 avian influenza virus on Wednesday.
The bird flu has been spreading rapidly through US dairy cattle herds since March, with infections confirmed in 16 states. Its jump from birds to cows surprised many virologists and raised concerns about the possibility that it could mutate enough to sustain human-to-human transmission.
For now, the US Centers for Disease Control and Prevention has not detected humans spreading the virus to each other and says the risk to the public remains low.
Still, 61 human cases have been confirmed across the country, with 34 of them in California. Many of these cases have been linked to infected cows or birds.
Newsom's declaration, which his office called a "proactive action," followed the detection of new cattle infections on dairy farms in Southern California, according to the office's statement.
"This proclamation is a targeted action to ensure government agencies have the resources and flexibility they need to respond quickly to this outbreak," Newsom said in a statement.
The FDA has said that grocery-shelf beef and dairy continue to be safe to consume. However, the FDA and unaffiliated virus experts have advised against drinking raw milk, which is not pasteurized and can contain harmful microorganisms.
"While the risk to the public remains low, we will continue to take all necessary steps to prevent the spread of this virus," Newsom said.
Also on Wednesday, the CDC confirmed the first case of severe symptoms in a human H5N1 infection, in Louisiana.
Slowing bird flu's spread
The H5N1 virus was first detected in a California cow on August 30. Since then, the governor's office reported, the state has distributed millions of pieces of protective equipment to dairy-farm workers and run a public education campaign.
Infectious-disease experts have previously told BI that limiting the virus's spread through cows can help reduce the odds of sustained human transmission.
That's because the more the virus replicates itself, the more opportunities it has to mutate, and the more new mutations can take hold and spread to new animals. As H5N1 spreads in cattle, a mammal population that lives close to humans, it gets more chances to adapt to humans.
"There's such a vast amount of virus at the moment. And clearly it is changing, and it's doing new and unexpected things," Christopher Dye, an epidemiologist and senior research fellow at the University of Oxford, told BI in June.
In a paper in the medical journal BMJ, Dye and his colleague Wendy Barclay argued that the risk of a major human outbreak was "large, plausible, and imminent" β but not inevitable.
When that paper was published in early June, there had only been three confirmed human cases in the US.
"Influenza has always been a concern for decades and decades, and this particular form of influenza for at least two decades," Dye said. Bird flu, he added, has "risen to a level of concern, I think, which is greater than ever before."
The Arctic is rapidly changing from the climate crisis, with no "new normal," scientists warn.
Wildfires and permafrost thaw are making the tundra emit more carbon than it absorbs.
From beaver invasions to giant holes, drastic changes in the Arctic are affecting the entire planet.
From Alaska to Siberia, the Arctic is changing so rapidly that there is no "normal" there now, scientists warn. The consequences reach across the globe.
The Arctic tundra now releases more carbon than it naturally draws down from the sky, as wildfires burn down its trees and permafrost thaw releases potent gases from its soil.
Once-brown regions are turning green with vegetation, while green areas are turning brown and barren. Sea ice and herds of caribou are disappearing.
This summer was the wettest on record for the Arctic overall, as rain is becoming more common than snow in some areas. Region by region, though, rainfall and the snow season are knocking down both high and low records.
Decades of data on "vital signs" suggest that "the Arctic exists now within a new regime, in which conditions year after year are substantially different than just a couple of decades ago," Twila Moon, a scientist at the National Snow and Ice Data Center, said in a briefing on Tuesday.
"Climate change is not bringing about a new normal," she added. "Instead, climate change is bringing ongoing and rapid change."
That's because the Arctic is warming about four times faster than the rest of the planet, according to previous research.
The increase in average temperatures is changing weather and landscapes in the Arctic, speeding up the climate crisis worldwide.
Giant holes, beaver invasions, and polar wildfires
For example, beavers are moving into Alaska's tundra and transforming its waterways with their dams, as warmer conditions have brought more wooded, comfortable riverbanks for them.
In Siberia, a giant hole in the ground is rapidly growing because the permafrost βΒ a layer of soil that used to be permanently frozen βΒ is thawing.
That's an extreme example, but melt and thaw is happening all over the planet's northernmost regions. Combined with drastic swings in weather year-to-year, these changes are wreaking havoc on Arctic landscapes, ecosystems, and people.
"These dramatic differences are making it difficult for communities to plan and they create safety issues for people who are used to more stable ice, snow, and temperature," Moon said.
She was presenting the Arctic Report Card, an update that the National Oceanic and Atmospheric Administration publishes each year, at the fall meeting of the American Geophysical Union.
This year's report revealed a crucial shift in northern landscapes: The Arctic tundra is no longer a net carbon sink, with its boreal forests pulling carbon dioxide from the sky. Now it's a net source of carbon emissions.
"This transition from a carbon sink to a source is of global concern," Brendan Rogers, a scientist studying the tundra at the Woodwell Climate Research Center, said in the briefing.
He added that the tundra's carbon emissions are relatively small for now, "but it's that transition that we're concerned about."
This shift is partly due to giant polar wildfires burning down tundra vegetation and all the carbon it's stored. It's also because of permafrost thaw, which releases large amounts of methane βΒ a heat-trapping gas more potent than carbon dioxide β as bacteria in the soil digest thawing plant matter.
Meanwhile,rising Arctic temperatures are driving ice melt, including on the Greenland Ice Sheet, which is a major contributor to sea-level rise worldwide. Rising oceans are already increasing flooding in coastal cities across the planet.
For example, US coastal cities from Boston to San Diego have seen more and more flood days per year every decade since 1950, according to the Environmental Protection Agency.
Arctic science is more important than ever
Reporters asked the NOAA scientists about the incoming Trump administration and whether they were concerned about losing funding for their Arctic research.
"The need, the requirement, the demand signal if you will, is higher than ever before," Richard Spinrad, the NOAA Administrator, said in the briefing.
Changes in extreme weather and sea level across the globe show that "there's a need for these investments to increase right now," he said, adding that studies have shown "the return on those investments is extraordinary, in many cases 10 to 1 in terms of protection of lives and property."
Jared Isaacman has flown two SpaceX missions to space and is slated to fly two more.
However, Isaacman may no longer fly those missions now that President-elect Donald Trump has tapped him to lead NASA.
Isaacman is the founder and CEO of a payments-processing company called Shift4,but he's more famous for conducting the world's first commercial spacewalk in September.
The spacewalk was the main feature of the first mission of the Polaris Program, which Isaacman started in partnership with SpaceX to supercharge the company's human-spaceflight capabilities as it aims for the moon and Mars.
The program is scheduled to fly two future missions, including the first human flight aboard SpaceX's Starship mega-rocket.
Isaacman has previously indicated that he would be on board that flight. It would be a crucial step in Elon Musk's plans to establish a human settlement on Mars using Starship.
The NASA nomination throws that mission into uncertainty, Isaacman acknowledged on Wednesday.
"The future of the Polaris program is a little bit of a question mark at the moment. It may wind up on hold for a moment," Isaacman said at the Spacepower 2024 conference in Orlando, according to Reuters.
Indeed, shortly after his nomination, experts told Business Insider that it was unlikely Isaacman would fly to space during his term as NASA Administrator.
"Well, it certainly has never happened before," John Logsdon, the founder of the Space Policy Institute at George Washington University, told BI.
That doesn't mean it can't happen, but Logsdon added, "NASA Administrator is a full-time, high-level government job. Taking time off to train for and carry out another spaceflight seems to me to be a little implausible."
If Isaacman wanted to fly a SpaceX mission during his NASA term, "that would take some thought on his part and the rest of the team," George Nield, a former head of the FAA's office of commercial space transportation, told BI. "What's the risk, what's the benefit, what happens if there's a bad day, and are there succession plans?"
Nield co-authored a 2020 analysis which calculated that US spaceflight has a 1% fatal failure rate, because four out of nearly 400 spaceflights have ended in deadly malfunctions. That's a rate 10,000 times greater than commercial airliners.
The US Senate has to confirm Isaacman's nomination before he can take office.
"Having the boss of the enterprise take the risk of spaceflight would be unusual, but we live in unusual times," Logsdon said.
Trump announced in a Truth Social post on Wednesday that his choice for NASA Administrator is Jared Isaacman β a CEO, fighter-jet pilot, and two-time SpaceX astronaut.
Isaacman is not exactly a traditional pick. For one, he would be the first billionaire to lead the agency. More importantly, though, he's on the cutting edge of the new commercial space age, where private companies are becoming the biggest actors in space.
Some past NASA administrators were former NASA astronauts. Others were former executives from the aerospace industry. Many were politicians β including Trump's last NASA chief, Jim Bridenstine, and the current administrator, Bill Nelson.
Isaacman is none of those things. He has, however, flown to space in a Crew Dragon spaceship, conducted the first-ever commercial spacewalk in a brand-new SpaceX spacesuit, and plans to fly on future missions with the company βΒ aboard its Starship mega-rocket, no less.
The nomination, which still has to be confirmed by the Senate, suggests that Trump wants to shake things up at NASA.
"He certainly has the potential to be a disruptor," Leroy Chiao, a former NASA astronaut and International Space Station commander who now works in consulting, told Business Insider. "I think it's a great pick. It's much better than just status quo β another retiring member of Congress."
It's also another signal that Trump might make a big push to put the next humans on the moon, and even the first humans on Mars.
Speeding up the road to Mars
Isaacman's enthusiasm for space exploration isn't his only bona fide. He also has a businessman's mindset and a close relationship with Elon Musk. The two share the goal of getting humans to Mars.
Chiao hopes Isaacman can speed up the process.
Indeed, in a post on X accepting the nomination, Isaacman wrote that NASA would help make humanity "a true spacefaring civilization."
"Americans will walk on the Moon and Mars and in doing so, we will make life better here on Earth," he added.
NASA is already working on it. The Artemis programbegan as the last Trump administration's iteration of a multi-president effort to send humans to deep space again. Artemisaims to send astronauts back to the moon for the first time in over 50 years, and eventually to use the moon as a jumping-off point to send people to Mars.
However, Artemis is years behind schedule and billions over budget, largely due to technical and programmatic challenges with the giant Space Launch System that NASA is building for moon missions. Many industry commentators see SLS as a waste of government funds, when NASA could instead lean on commercial heavy-lift rockets like Starship.
"Frankly, we have been at the status quo of this exploration program in one form or another over the last several presidents since 2004," Chiao said, "and we're not even close to launching the first astronaut on a new vehicle."
In fact, NASA just pushed back the launch date for its first crewed Artemis mission, set to fly around the moon using SLS. On Thursday the agency delayed the mission by another seven months, to April 2026, citing issues with the system's Orion spaceship.
That's the slow-moving status quo that Trump might aim to shake up.
To that end, efficiency may be a top priority for Isaacman. That could mean reassessing Artemis entirely or cutting back some of NASA's centers and facilities nationwide, according to Abhi Tripathi, a former NASA engineer and SpaceX mission director who now leads mission operations at the UC Berkeley Space Sciences Lab.
"I definitely think SLS will be on the chopping board," Tripathi told BI.
First, though, Isaacman will have to go through Congress.
"He is going to ruffle a lot of feathers," Chiao said.
Pushing through Congress
Congress can be a formidable wall for anyone trying to revolutionize NASA.
In places like Alabama and Southern California, a status quo NASA fuels the work of legacy aerospace contractors like Boeing and Northrop Grumman.
"The majority of members of Congress want jobs in their district, and they look at the space program primarily through that lens," Tripathi said.
Plus, he added, "the lobbying arms of all of those big contractors will be basically camped outside their congressional representative's office, asking them to thwart any big plans that would change the status quo greatly."
It'll all come to a head when the Trump White House makes its budget proposal. That's when Congress will approve or deny any cuts or reprioritizations that Trump and his NASA Administrator try to make.
If Trump wants to put boots on Mars fast, he'll have to convince individual Congress members to push those changes through.
"I think Jared is a very smart and capable individual," Tripathi said, "but his ability to wield power will completely depend upon how much his president will back him up."
A 7.0-magnitude earthquake struck off the shore of Northern California Thursday morning.
Tsunami warnings have been lifted across northern California and southern Oregon.
Aftershocks are ongoing, and there's a small chance they could outdo the first quake.
A major earthquake struck near California's coast on Thursday, and aftershocks are still ongoing.
The 7.0-magnitude earthquake struck at about 10:44 a.m. Pacific Time. Its epicenter was offshore, about 62 miles west-southwest of Ferndale, California, according to data from the United States Geological Survey.
The USGS website reported more than 35 smaller quakes across that area over the ensuing three hours, of magnitudes ranging from 2.5 to 4.7, including two quakes that occurred inland.
"There's been quite a lot of aftershocks," Harold Tobin, Washington's state seismologist and the director of the Pacific Northwest Seismic Network, told Business Insider.
As of Thursday afternoon,the USGS forecasts up to 130 aftershocks with a magnitude of 3 or higher within the next week, and a 53% chance of aftershocks larger than magnitude 5.
"It's perfectly plausible that there could be a larger aftershock or more than one larger aftershock," Tobin said.
The USGS estimates the odds are 1 in 100 of an aftershock with a magnitude of 7 or greater.
The fault that slipped
The fault region which produced the 7.0 earthquake is a very seismically active one.
It's called the Mendocino triple junction because three different tectonic plates meet there: the Pacific, North American, and Juan de Fuca plates.
It's right between two notorious earthquake zones, at the northern end of the San Andreas fault and the southern end of the Cascadia Subduction Zone. The CSZ has some of the planet's greatest seismic potential, capable of producing quakes as big as 9.0.
The Mendocino triple junction, however, is less impressive.
"Somewhere in the magnitude sevens range is about as big as things seem to get out there," Tobin said.
The region has produced five earthquakes of magnitude 7 or larger in the past century, according to USGS.
The Thursday quake could have slightly increased the chance of other earthquakes along adjacent faults by increasing stress in those areas.
"It's unlikely that it had a really large, significant impact" on those fault systems, though, Tobin said. The odds are "not zero, but very low," he added.
Tsunami scare
The initial quake triggered tsunami warnings and evacuations β which have since been canceled β along the coast of northern California to southern Oregon, including the San Francisco Bay Area.
The warnings lasted about an hour. The National Tsunami Warning Center canceled them around 11:54 a.m. local time, saying there was no longer a threat.
Most likely, the reason there was no tsunami is that the earthquake came from plates moving side-by-side against each other. This is called a strike-slip earthquake. Because the motion was mostly horizontal, and not vertical, it didn't push the ocean above upward to create a wave.
Even so, the warning was "warranted," Tobin said.
"Until we know enough parameters of the earthquake and can verify whether there is or isn't an actual wave, it's wise to have those warnings," he added.
Possible earthquake damage
The USGS also reported on X a "low likelihood of shaking-related fatalities. Some damage is possible and the impact should be relatively localized."
Governor Gavin Newsom declared a state of emergency for three counties in Northern California which were near the offshore epicenter of the quake.
"We're concerned about damage," he said in a press briefing, adding that the declaration would allow the state to "provide more resources."
According to CNN, about 10,000 homes and businesses in Humboldt County βΒ the area nearest the epicenter β were without power immediately after the large quake. As of Thursday afternoon, though, PowerOutage.us reported fewer than 500 customers without power there.
Newsom said that "early damage assessments are being made," but that the state had no additional information to share yet.
This is a developing story, check back for more information.
America's first large offshore wind farm began powering homes. The Bill Gates-backed startup Graphyte opened its first carbon-removal plant in Arkansas. Another startup, Sublime Systems, secured a site and funding for its first low-carbon cement manufacturing facility.
There's also been a "corporate climate pivot," according to a report by Breakthrough Energy, a climate investment firm and startup catalyzer founded by Gates.
"We noticed a subtle, but important, perspective shift from both the investors and corporations we engage with," Gates wrote in an intro to the report, which the firm published in October with the tagline "climate tech has arrived."
More than just reducing their carbon footprint, corporate leaders "want to get in at the ground floor of new industries that, one day, will be crucial to the survival of their businesses," Gates wrote.
Other industry experts also told Business Insider that climate tech is picking up steam, and now emerging companies need more funding to scale up.
Corporate investment in climate tech
Breakthrough Energy focuses on its own partners in the report, such as American Airlines investing in a startup making hydrogen-based plane fuel. It's not the only VC firm seeing large corporations lean into climate tech more, though.
A number of long-standing corporate partners, like the chemicals giant BASF or the building-materials manufacturer Saint-Gobain, work with the nonprofit climate-tech incubator Greentown Labs to support early-stage companies.
Aisling Carlson, the senior vice president of partnerships at Greentown, told BI that the firm's oldest corporate partners have been hiring, "beefing up" their teams that invest in emerging climate tech.
"Their approach to climate innovation and their internal expertise has matured," Carlson said.
Meanwhile, other corporations are beginning to engage with climate tech for the first time. Carlson said Greentown has seen new interest from corporations that haven't invested much in climate tech, though no partnerships have been publicly announced yet.
"They are all thinking about their carbon footprint and how they can decarbonize," she added.
Don't forget about old reliables like solar
Though new technologies, like direct air capture plants that suck carbon out of the sky, can be part of the solution, Foley wants investors and politicians to remember that fighting climate change is a race against time.
"Let's deploy things that actually are cheap enough and scalable enough and ready enough," like solar power, battery storage, EV charging stations, and other tech that's already proliferating, he said.
We also have to shut down coal-fired power plants and plug abandoned gas wells that leak methane, Foley said. Efforts to stop deforestation can prevent huge amounts of carbon emissions and they're "desperately starved for money," he added.
Foley said that Gates has a history of investing in "science fiction experiments" that don't move fast enough, such as small modular nuclear reactors. After nearly 20 years of development and Gates's investment, there still isn't a single one in operation.
Sustainable aviation fuel is a similar "boondoggle," Foley said.
"That's a science experiment still, and it doesn't need or deserve billions of tax dollars," he said, adding that public funding should go to reliable solutions.
Breakthrough Energy did not respond to a request for comment.
VC can 'prime the pump' on garage innovators
Lots of futuristic climate tech just needs the funding to deploy and scale up, Gates wrote. The Breakthrough Energy report argues that venture capitalists, investors, or corporations should get in on it now, at the ground floor.
"By waiting, venture firms are only hurting their own bottom lines," the report says. By getting in early, though, investors can "prime the pump" and help early-stage companies design a product that's scalable and capable of attracting even bigger investment.
However, funding for climate tech slowed down this year, Carlson said, possibly due to investors taking a "wait and see" stance in the lead-up to the US election.
Indeed, Biden administration initiatives have boosted climate tech in recent years including the Inflation Reduction Act, the Bipartisan Infrastructure Law, and the CHIPS and Science Act.
New policies have driven more government investment in green concrete and steel, according to the Breakthrough Energy report, and the IRA created more than two dozen tax credits for investing in clean-energy projects. Breakthrough concluded those credits could unlock "more than $1 trillion in private sector investment."
However, incentives like that could change with the new Trump administration.
"What I am hopeful for is that corporate commitments to net zero targets will continue to drive innovation," Carlson said. "And if there are unfavorable federal policies, that the private sector can continue to play a driving role in ensuring at least that the early-stage climate technologies are getting to market."
Isaacman has flown to space twice aboard SpaceX's Crew Dragon, on flights he commissioned, funded, and commanded βΒ including a mission where he conducted the first-ever commercial spacewalk in September.
So who is Jared Isaacman, and how did the entrepreneur end up as Trump's NASA pick? Read on to learn about his career rise.
Isaacman decided to drop out of high school at the age of 15.
At the age of 15, Isaacman decided to drop out of high school and take the GED, according to the Netflix docuseries "Countdown: Inspiration4 Mission to Space."
"I was a horrible student," Isaacman said in the series. "And I wasn't, like, happy in school, either."
He described his younger self as independent and said he didn't understand things like raising your hand to go to the bathroom.
At 16, he founded a multibillion-dollar payment-processing company in his parents' basement.
Isaacman founded United Bank Card in 1999.
The company, now called Shift4, offers mobile-payment software, point-of-sale solutions, and online payments for various businesses.
Isaacman said in the Netflix docuseries that when he started the company, he would wake up every day at 7:30 a.m. and fall asleep on the keyboard at 2 or 3 in the morning.
By 2020, he took the company public. Today, Shift4 processes over $260 billion annually and serves over 200,000 customers, according to its website.
Isaacman has a wife and two kids.
Isaacman has known his wife, Monica Isaacman, for most of his life. The two come from the same town and got married in 2012. They now live in New Jersey with their two daughters.
"I want my kids to see humans walking on the moon and Mars," Isaacman told BI.
His wife said in the docuseries that she had good and bad dreams leading up to his first SpaceX mission, Inspiration4, which launched in 2021.
She said while she wouldn't want him to compromise on his dreams of going to space, she worried about what could happen if something went wrong.
Isaacman told BI in the interview that his family and wife were much more enthusiastic about the Polaris Dawn mission this time around, thanks to a successful first mission.
While there are still risks, he told BI his family is aware and accepts them.
He also founded Draken International.
Isaacman founded Draken International in 2012. The company is a private aircraft provider that also trains pilots for the US military, the UK, and NATO countries.
In 2019, Isaacman sold the company to Blackstone.
Isaacman became a billionaire in 2019.
Isaacman hit billionaire status in 2020 after selling Draken International and taking Shift4 public. His net worth isΒ estimatedΒ at $1.7 billion, according to Forbes.
He always had a passion for flying planes.
Isaacman said in the Netflix docuseries that he took an early interest in flying and went to flight school at a local airport in 2004.
At the time, he was feeling burned out from starting his company and described flying as "therapeutic." Isaacman also set a world speed record for flying around the globe in 2009.
"I do believe you only get one crack at life," Isaacman said in the docuseries. "To the extent you have the means to do so, you have this obligation to live life to the fullest. You never know when it's going to be your last day."
He added in the docuseries that this philosophy had taken him to fly in air shows as part of a seven-ship formation aerobatic team and on mountain-climbing expeditions in Antarctica.
He's involved with philanthropy.
Isaacman has been involved in several charitable causes and organizations, including the Make-A-Wish Foundation and St. Jude Children's Research Hospital.
Hisfirst SpaceX mission raised over $240 million for St. Jude and was named Inspiration4 to inspire support and raise awareness for the research hospital.
Isaacman and his wife have also committed to The Giving Pledge, a charitable campaign founded by Bill Gates, Melinda French Gates, and Warren Buffett in 2010.
The Giving Pledge serves as a commitment from wealthy people to donate the majority of their wealth to philanthropy.
Isaacman's first mission to space took place in 2021.
In 2021, Isaacman funded and led the first civilian mission to space, called Inspiration4. The mission was carried out by SpaceX 's Dragon capsule.
Isaacman previously told Business Insider that the prep for the mission was extensive and involved a lot of studying and physical tests.
"The academics were pretty intense," Isaacman said, adding that there were thousands of pages across a hundred manuals to learn about SpaceX's Falcon and Dragon aircraft.
It also involved crew members drawing blood from each other and learning how to take skin samples to prepare for increased radiation levels on the trip.
Isaacman commanded the first-ever privately funded spacewalk
On September 10, Isaacman and three other crew members successfully took off on their way into orbit for the first-ever privately funded spacewalk.
Polaris Dawn lifted off from Launch Complex-39A at NASA's KSC, which also saw the launches of other historic missions, such as the Apollo 11 moon landing. Dragon and the Polaris Dawn crew safely arrived back on the coast of Florida on September 15.
Trump nominated Isaacman to lead NASA
In an X post on Wednesday, Isaacman called the nomination "the honor of a lifetime" and suggested that human space exploration would be a top priority.
Space-industry experts told BI that Isaacman is not a traditional pick for NASA Administrator, but his background in commercial spaceflight would benefit the agency.
"They need someone who is not afraid to try something new if the old ways aren't working," George Nield, a former head of the FAA's office of commercial space transportation, told BI.
Michelle Hanlon, executive director of the Center for Air and Space Law at the University of Mississippi School of Law, called Isaacman "an inspired pick," in part due to his "stellar" managerial skills.
"He has shown a real commitment to increasing access to space, and I think he is going to be a great person to promote space to the general public," she said.
This story was originally published on September 11, 2024, and most recently updated on December 4, 2024.
Isaacman, who is also the CEO of the payments company Shift4, recently made history by leading the first private spacewalk with SpaceX's Polaris Dawn mission. The five-day mission took Isaacman and three others further from Earth than anyone has traveled since the Apollo moon missions.
"We have to keep going," Isaacman said about space exploration in a November interview with Business Insider. "We just got to proceed with caution and just make sure we get it right. And if we do, we stand to learn so much that can change the course of trajectory of humankind."
Isaacman also previously helped finance and lead the world's first all-civilian private spaceflight. That was also a SpaceX mission, called Inspiration4, which Isaacman commanded.
"Jared will drive NASA's mission of discovery and inspiration, paving the way for groundbreaking achievements in Space science, technology, and exploration," Trump wrote in a Truth Social post announcing his nomination.
Trump pointed to Isaacman's passion for space and "exceptional leadership," demonstrated by his 25 years as the founder and CEO of Shift4. Trump also highlighted Isaacman's work as the cofounder and former CEO of Draken International, a defense aerospace company that supported the US Department of Defense, the UK, and NATO countries.
"I think that's a creative and hopeful recommendation," George Nield, a former head of the FAA's office of commercial space transportation, told Business Insider. "Jared has a lot of vision and enthusiasm."
He added that, "I would interpret this as at least an openness, if not strong advocacy, for industry playing an important role for the nation's space programs going forward."
Elon Musk, who is the founder and CEO of SpaceX and whom Trump tapped to lead a new Department of Government Efficiency, said "Congratulations" to Isaacman on X.
This would be Isaacman's first-ever role in government.
"He doesn't have experience as a government insider, and that's probably a good thing," Leroy Chiao, a former NASA astronaut and International Space Station commander who now works in consulting, told BI. "He certainly has the potential to be a disruptor, so I think it's a great pick. It's much better than just status quo."
'An era where humanity becomes a true spacefaring civilization'
Following his nomination, Isaacman wrote in a post on X that it is "the honor of a lifetime to serve in this role" and work alongside NASA.
"With the support of President Trump, I can promise you this: We will never again lose our ability to journey to the stars and never settle for second place," Isaacman said, adding that "Americans will walk on the Moon and Mars."
Isaacman added that space holds potential for advancements in various areas including manufacturing, biotechnology, and possibly new energy sources. He also shared his vision for humanity to become a "spacefaring civilization" and described a "thriving space economy" with opportunities for people to work in space.
"I want my kids to see humans walking on the moon and Mars," Isaacman previously told BI.
Michelle Hanlon, executive director of the Center for Air and Space Law at the University of Mississippi School of Law, told BI in an email that this was a "perfect direction for NASA."
It's unclear whether his new role would impact his work with SpaceX or any plans he has to fly on future missions. The Polaris Program Isaacman is leading includes two more missions over the next six to nine years, including the first crewed flight of SpaceX's Starship mega-rocket.
Nield said Isaacman and his team at NASA would likely assess the tradeoffs and the risk of him flying into space during his term as Administrator.
"NASA's got a great team. They've got super smart and experienced and motivated people, but they need a leader. They need a communicator," Nield said. "They need someone who is not afraid to try something new if the old ways aren't working. So I think I'm excited about that choice."
Some Florida real-estate developers are building what they call hurricane-resistant communities.
Techniques used include tying homes down with steel straps and reducing flooding with "smart lakes."
While no home can be hurricane-proof, these strategies can minimize potential damage, experts said.
Hurricane Milton was barreling toward William Fulford's front door. The mayor of nearby Tampa, Florida, was pleading on television for area residents to leave or die. Still, Fulford, a 76-year-old retired homebuilder, was staying put.
"A lot of people would say I'm crazy," Fulford told Business Insider by phone on October 8, as the storm gained strength in the Gulf of Mexico. "But my house is great."
In 2022, Fulford bought a $1.25 million home in Hunters Point, a community in Cortez, Florida, where properties are raised 16 feet above the ground and tied together with steel straps. Fulford, whose home suffered minimal damage from Hurricane Milton, told Business Insider he believes his home is "hurricane-proof."
More than a few developers are betting on Florida's future by building hurricane-resistant communities like Fulford's. Hurricane season officially ends on November 30, but the movement toward resilient homes has increased as the climate crisis drives fiercer storms.
The prospect appeals to Florida homeowners grappling with stress and uncertainty as home insurance premiums and homeowners' association, or HOA, fees rise and the risk of severe storm damage mounts. After Hurricanes Helene and Milton in September and October, respectively, the state suffered an estimated $21 to $34 billion in damages to commercial and residential properties, including uninsured properties, according to real-estate analytics site Corelogic.
About two hours southeast of Hunters Point is a development called Babcock Ranch, which bills itself as "The Hometown of Tomorrow." Its builders made efforts to protect its 4,000 homes on about 17,000 acres from storms, including moving utilities underground and avoiding paths of natural water runoff.
A rep said that in the days before Hurricane Milton, Babcock Ranch saw a 390% increase in daily visits to its website. Hunters Point's developer said that two new homes have sold since last month's storm.
Three building experts told Business Insider that no home can be hurricane-proof. However, Leslie Chapman-Henderson, the president and CEO of the Federal Alliance for Safe Homes, said that Hunters Point and Babcock Ranch are good examples of what hurricane resiliency can look like.
Building entire resilient communities β instead of one home with beefed-up protections on a block with regular homes β can protect neighborhoods and property values against Florida's unsettled future, she added.
"Our wish is to see all developers do this because they're on the leading edge," Chapman-Henderson said.
Hunters Point homes are high off the ground and air-tight
Hunters Point is in Florida's last working fishing village an hour south of Tampa.
The resiliency of its homes begins with their height. Located on a peninsula jutting out into Sarasota Bay, the development is just feet away from the coastline and vulnerable to storm surges like those seen during Hurricanes Helene and Milton, which reached almost seven feet.
To counteract that risk, Hunters Point homes βΒ which were developed and tested in a warehouse for 18 months βΒ are built so that the bottom floor is a garage and storage, the middle floor is the home's first floor, and another level above has bedrooms β all connected by an elevator.
"You don't step into the house until you're 16 feet above the flood zone," developer Marshall Gobuty told Business Insider.
Currently, 31 of the 86 planned units at Hunter's Point have been built, with homes ranging in price from $1.45 million for nearly 1,700 square feet to $1.69 million for over 3,400 square feet.
Another feature of the homes is an extra-fortified base, in which the slab and foundation are poured together as one piece. The homes' walls are built with 2x6 beams instead of 2x4 beams to increase resiliency and allow for more insulation. The sides of the walls, the ceilings, and the roof are then filled in with closed foam to make the home airtight.
Every level is reinforced with metal straps all the way down to the foundation to hold the home together.
These connections β roof to walls, walls to each other, and walls to foundation β are fundamental to building a house that can withstand hurricane-force winds.
Chapman-Henderson said the real innovations built into these homes are the fortifications against the wind: the walls bolted into the foundation and the sturdier wood in the frames.
Any vulnerability in those structural connections could doom the whole house. When that happens, "usually roofs blow off first because they're not connected well to the walls, and then the walls don't have any lateral support, and they go, and you've lost the whole building," Mike O'Reilly, a licensed engineer and construction instructor at Colorado State University, told BI.
In Hunters Point homes, though, "everything is connected. There are no seams," Gobuty told BI. "Every house is built like a Yeti cooler."
Babcock Ranch uses "smart ponds" to manage flooding
Babcock Ranch in Punta Gorda, Florida, is built on land 30 feet above sea level, far from the coast.
So far, 3,752 homes have been built out of a planned 19,500 units. The development functions like a city, with an elementary school, a middle school, a high school, a shopping district, a recreation lodge, and dozens of hiking trails. Homes on the market range from a two-bedroom condo for $255,000 to a four-bedroom single-family home with its own pool for $1.695 million.
When developer Syd Kitson purchased the land in 2006, his team spent hours poring over maps dating back to the 1940s to find the property's natural flowways, which are how excess water naturally runs out of the area during flooding.
The team intentionally sacrificed building thousands of units to leave that land untouched.
"That's part of working with Mother Nature, rather than working against Mother Nature," Kitson told BI.
Babcock Ranch also has "smart lakes," or man-made bodies of water throughout the development. These lakes have solar-powered pumps with predictive analytics that raise and lower the lake's height when a storm nears. If the area expects major flooding, the smart lakes will lower to prepare for the increased rainfall.
"Our philosophy is to do everything in our power to be as resilient as we possibly can," Kitson said.
Babcock Ranch welcomed its first residents in 2018. It faced its first major test in 2021 when the eye of Category 4 storm Hurricane Ian brought 150 mph wind gusts to the development. The property only sustained minimal damage, including fallen trees and a few broken solar panels, Kitson said.
Downed power lines and dayslong blackouts often affect large swaths of the state following major hurricanes. Babcock Ranch placed all utilities, including water, electricity, and wastewater, underground to prevent that.
"You won't see a single utility pole in Babcock Ranch," Kitson said.
The submerged power poles are built in concrete tubes designed to withstand 165 mph wind gusts.
Chapman-Henderson, of the nonprofit that advocates for safe homes, called the smart lakes and buried utilities "innovative" and added that recent storms have proven these strategies are effective.
Babcock Ranch is so well regarded for its safety during a storm that the elementary school's fieldhouse serves as a state- and county-designated evacuation center. Built to withstand 150 mph wind gusts, the fieldhouse provided shelter for 1,300 Floridians during Hurricane Milton.
"We're not a place where you evacuate. We're a place where people being ordered to evacuate come," Kitson said.
Hurricane resistance is the future of Florida homebuilding
Hunter's Point and Babcock Ranch are part of a growing movement for more resilient homes.
Chapman-Henderson warned, however, that residents shouldn't let their home's sturdiness make them complacent. They should still evacuate if authorities call for it.
"We can build to withstand these events, but we should never say it's absolute without fail," she said.
Calling a house 100% hurricane-proof is "like calling the Titanic unsinkable," O'Reilly said.
Though there isn't a single national standard for hurricane-resistant buildings, Fortified β a program run by the Insurance Institute for Business & Home Safety, an industry-backed research group β evaluates one of the most critical structures for a home's resiliency: its roof. Fortified grants certifications to homeowners who strengthen their roofs through different methods, such as using grooved, ring-shank nails instead of traditionally smooth ones.
More homeowners are requesting to have their roofs certified as stronger-than-average, Fred Malik, managing director of Fortified, told BI. Fortified certifications have risen from less than 1,000 in 2016 to nearly 12,000 last year, bringing the grand total to nearly 70,000 over the program's lifetime, Malik added. The program anticipates adding another 17,000 by the end of this year.
Though Hunters Point and Babcock Ranch have not yet participated in Fortified, Malik said the measures their builders are taking seem effective.
"I get really nervous when anybody refers to anything as something 'proof,'" Malik told BI. "But they are making some really good decisions."
SpaceX and other companies plan to fill the skies with tens of thousands of internet satellites.
Satellite mega-constellations could harm the atmosphere, say scientists calling for more research.
Elon Musk, whose Starlink satellite constellation is the biggest, wields power in the new Trump administration.
SpaceX's Starlink and other mega-constellations of satellites could damage the atmosphere in ways we don't yet understand, scientists say.
The number of satellites in Earth's orbit has skyrocketed from about 1,000 in 2010 to more than 10,000 today. According to a government report, an additional 58,000 satellites could launch by 2030,largely from SpaceX, OneWeb, Amazon, and the Chinese government β all toΒ connect the entire planet to the internet.
Research suggests the ozone layer that protects us from powerful solar radiation could be at stake.
About 100 scientists signed a letter in October asking the Federal Communications Commission, which regulates satellite launches in the US, to pause mega-constellations.
"We should look before we leap," the letter reads, adding, "The environmental harms of launching and burning up so many satellites aren't clear."
Elon Musk β who sits at the helm of the world's dominant satellite constellation, Starlink β has publicly criticized some regulations affecting his companies andhas positioned himself to push against regulation with the new Trump administration.
Starlink accounts for more than half of the 10,560 active satellites as of November 15, according to tracking by the Harvard astronomer Jonathan McDowell. SpaceX has filed for permission to fly 30,000 more satellites.
SpaceX did not respond to a request for comment.
Satellites burning up in the atmosphere
Studies have found that rocket launches, such as those that put satellites into space, emit pollutants like carbon dioxide and black carbon, which could trigger processes that deplete Earth's protective ozone layer.
That's just the launch. Most satellites eventually fall out of orbit because of malfunction or because they're reaching the end of their lives. This "reentry" prevents dead satellites from becoming dangerous, uncontrollable space junk, but it also causes them to burn up as they plow through the atmosphere, releasing metals like aluminum.
Due to the sheer number of satellites expected to fly, die, and re-enter in coming years, future mega-constellations could inject 21 times more aluminum oxides into the upper atmosphere than 2022 rates, according to a paper published in the Geophysical Research Letters in June.
Aluminum oxides can linger for decades and cause "significant ozone depletion," the researchers wrote.
There may also be impacts scientists have not yet discovered β "unknown unknowns," Nilton Renno, an atmospheric scientist who co-signed the letter, told BI.
An accurate prediction of all possible impacts "should be the basis for any relevant policy," Joseph Wang, a coauthor of the aluminum-oxides paper and a professor of aerospace and mechanical engineering at the University of Southern California, told BI in an email. At the moment, no such prediction exists.
For now, satellites are small potatoes compared to pollution from other industries. It's unclear how quickly their impact will balloon.
Another study found that about 10% of aerosol particles inΒ the stratosphereΒ contain metals from satellites and other spacecraft, and that amount could increase to about 50% in the next few decades.
There's no environmental review for mega-constellations
The 100-scientist letter asks the FCC to pause new satellite launches, conduct environmental reviews under the National Environmental Policy Act (NEPA), and end a rule that excludes satellites from those review requirements.
The letter says the exclusion "offends common sense," given the number of satellites in play.
In a 2022 report, the US Government Accountability Office also recommended that the FCC reassess the exclusion.
Indeed, an FCC spokesperson told BI that the agency plans to review its NEPA rules, which would include the satellite exclusion. That's because the Council on Environmental Quality updated government-wide regulations for implementing NEPA in May.
If the FCC finds that large satellite constellations significantly affect the human environment (such as Earth's atmosphere), it may have to start requiring environmental reviews.
Michelle Hanlon, the executive director of the Center for Air and Space Law at the University of Mississippi School of Law, agrees that more studies are needed but doesn't think that stopping satellite launches should be the solution.
"We can shut down the American space industry and there's still going to be launches," she told BI.
Musk's anti-regulation campaign
The incoming Trump administration may not be the most environmental-review-friendly, given Musk's anticipated role in it.
"There is a lot of waste and needless regulation in government that needs to go," Musk wrote on X after Trump announced a plan for the billionaire CEO to lead a new Department of Government Efficiency.
Musk and SpaceX have already clashed with regulators over environmental reviews. In September the company published a strongly worded statement about the Federal Aviation Administration's review requirements for operations in Texas, where its next-generation Starship rocket is based.
Then, in October, SpaceX sued the California Coastal Commission, an environmental regulator, after it blocked the company's request for additional launches. SpaceX alleged the commission had made the decision based on political bias.
Without an environmental review, it's unclear what the impact of SpaceX's Starlink plans will be.
SpaceX launched its Starship mega-rocket system on Tuesday for the sixth time.
SpaceX didn't attempt to catch the Super Heavy booster by a pair of "chopsticks" mid-air as planned.
Starship moving towards full, rapid reusability is key to Elon Musk's plans for Mars.
SpaceX launched its Starship mega-rocket for the sixth time on Tuesday, but the main event was canceled.
The space company successfully launched the 36-story-tall rocket system but ended up abandoning its plan to catch the Super Heavy booster upon its return to Earth with a giant pair of metal arms, nicknamed "chopsticks."
SpaceX achieved the major feat for the first time in October, during Starship's fifth test launch.
After about three minutes, Super Heavy released itself and fell back to Earth.
When the catch attempt was called off, the booster splashed down in the Gulf of Mexico nearly seven minutes after launch while Starship continued on toward space.
SpaceX officials said on the company's livestream that the catch wasn't attempted this time because "strict criteria were not met" and this was a known possibility before launch.
During Starship's fifth test flight in October, SpaceX successfully caught the Super Heavy booster with aΒ giant pair of metal arms, nicknamed "chopsticks," that caught it before it reached the ground.
SpaceX's next major milestone for Starship
Ultimately, Starship is designed to be the first ever fully, rapidly reusable rocket.
SpaceX has been reusing its fleet of Falcon 9 rockets for years, but only the first stage returns for reuse, the second stage is discarded after each launch.
Moreover, the Falcon 9 first stage lands on a barge in the ocean and must be retrieved for reuse, which takes extra time.
Starship is different. Both its first-stage Super Heavy booster and second-stage Starship are designed to be rapidly reusable by returning to the launch site after lift-off.
SpaceX's next major goal is to prove it can consistently retrieve Super Heavy and also retrieve Starship β but that milestone remains for another day.
For this test launch, Starship splashed down in the Indian Ocean as expected about an hour and five minutes after launch.
During its flight in space, Starship fired one of its Raptor engines for the first time, proving a capability it will need during future launches to return and touch down on land.
SpaceX also chose to launch Starship in the afternoon this time instead of the early morning, so that it can better observe Starship's landing, The New York Times reported.
SpaceX and Musk are racking up wins
Despite SpaceX not catching Super Heavy on its return to Earth, the test launch is still another successful step toward making Starship viable for orbital flights, moon landings, and eventually long journeys to and from Mars.
Tuesday's flight came just one month after the Starship's fifth test flight. That's a rapid turnaround for such a major test.
Maintaining this fast pace will be critical to achieving Musk's latest goal of sending the first Starships to Mars in just two years.
Ahead of the event, Trump announced on Truth Social that he'd be in attendance, writing, "Good luck to Elon Musk and the Great Patriots involved in this incredible project!"
Trump's presence indicates just how influential Musk may become in the next administration, which could be a boon for space exploration.
