A generation ago, when former NASA administrator Dan Goldin promoted the mantra of a "faster, better, cheaper" approach to the agency's science missions, critics often joked that NASA could only pick two.
That's no longer the case. NASA is finding success in its partnerships with commercial space companies, especially SpaceX, with lower costs, quicker results, and improved performance.
The Space Force and the National Reconnaissance Office, the US government's spy satellite agency, are also capitalizing on new products and services from commercial industry. In many cases, these new capabilities come from venture-backed startups already developing and operating satellites for commercial use.
Mission patches are a decades-old tradition in spaceflight. They can range from the figurative to the abstract, prompting valuable insights or feeding confusion. Some are just plain weird.
Ars published a story a few months ago on spaceflight patches from NASA, SpaceX, Russia, and the NRO, the US government's spy satellite agency, which is responsible for some of the most head-scratching mission logos.
Until recently, China's entries in the realm of spaceflight patches often lacked the originality found in patches from the West. For example, a series of patches for China's human spaceflight missions used a formulaic design with a circular shape and a mix of red and blue. The patch for China's most recent Shenzhou crew to the country's Tiangong space station last month finally broke the mold with a triangular shape after China's human spaceflight agency put the patch up for a public vote.
The payload fairing at the top of Gilmour Space's first Eris rocket was supposed to deploy a few minutes after lifting off from northeastern Australia. Instead, the nose cone fell off the rocket hours before it was supposed to leave the launch pad Thursday.
Gilmour, the Australian startup that developed the Eris rocket, announced the setback in a post to the company's social media accounts Thursday.
"During final launch preparations last night, an electrical fault triggered the system that opens the rocket’s nose cone (the payload fairing)," Gilmour posted on LinkedIn. "This happened before any fuel was loaded into the vehicle. Most importantly, no one was injured, and early checks show no damage to the rocket or the launch pad."
The next Starship launch may come as soon as next week. A test of its Raptor engines suggests SpaceX has resolved the issues that plagued its recent flights.
Gilmour Space, a venture-backed startup based in Australia, is about to launch a small rocket from its privately owned spaceport on a remote stretch of the country's northeastern coastline.
It's the first time anyone has attempted to reach orbit with a rocket designed and built in Australia. Gilmour's three-stage rocket, named Eris, could launch at any time during a 10-hour window as soon as Friday, local time. In the United States, the launch window runs from 5:30 pm EDT Thursday until 3:30 am EDT Friday.
This comes after a 24-hour delay due to an "issue in the ground support system" for the launch, Gilmour said Wednesday.
SpaceX fired six Raptor engines on the company's next Starship rocket Monday, clearing a major hurdle on the path to launch later this month on a high-stakes test flight to get the private rocket program back on track.
Starship ignited its Raptor engines Monday morning on a test stand near SpaceX's Starbase launch facility in South Texas. The engine ran for approximately 60 seconds, and SpaceX confirmed the test-firing in a post on X: "Starship completed a long duration six-engine static fire and is undergoing final preparations for the ninth flight test."
SpaceX hasn't officially announced a target launch date, but maritime warnings along Starship's flight path over the Gulf of Mexico suggest the launch might happen as soon as next Wednesday, May 21. The launch window would open at 6:30 pm local time (7:30 pm EDT; 23:30 UTC). If everything goes according to plan, Starship is expected to soar into space and fly halfway around the world, targeting a reentry and controlled splashdown into the Indian Ocean.
Welcome to Edition 7.43 of the Rocket Report! There's been a lot of recent news in hypersonic testing. We cover some of that in this week's newsletter, which is just a taste of the US military's appetite for fielding its own hypersonic weapons, and conversely, the Pentagon's emphasis on the detection and destruction of an enemy's hypersonic missiles. China has already declared its first hypersonic weapons operational, and Russia claims to have them, too. Now, the Pentagon is finally close to placing hypersonic missiles with combat units. Many US rocket companies believe the hypersonics sector is a lucrative business. Some companies have enough confidence in this emerging market—or lack of faith in the traditional space launch market—to pivot entirely toward hypersonics. I'm interested in seeing if their bets pay off.

Stratolaunch tests reusable hypersonic rocket plane. Stratolaunch has finally found a use for the world's largest airplane. Twice in the last five months, the company launched a hypersonic vehicle over the Pacific Ocean, accelerated it to more than five times the speed of sound, and autonomously landed at Vandenberg Space Force Base in California, Ars reports. Stratolaunch used the same Talon-A vehicle for both flights, demonstrating its reusability, a characteristic that sets it apart from competitors. Zachary Krevor, Stratolaunch's president and CEO, said his team aims to ramp up to monthly flights by the end of the year.
Kosmos 482, a Soviet-era spacecraft shrouded in Cold War secrecy, will reenter the Earth's atmosphere in the next few days after misfiring on a journey to Venus more than 50 years ago.
On average, a piece of space junk the size of Kosmos 482, with a mass of about a half-ton, falls into the atmosphere about once per week. What's different this time is that Kosmos 482 was designed to land on Venus, with a titanium heat shield built to withstand scorching temperatures, and structures engineered to survive atmospheric pressures nearly 100 times higher than Earth's.
So, there's a good chance the spacecraft will survive the extreme forces it encounters during its plunge through the atmosphere. Typically, space debris breaks apart and burns up during reentry, with only a small fraction of material reaching the Earth's surface. The European Space Agency, one of several institutions that track space debris, says Kosmos 482 is "highly likely" to reach Earth's surface in one piece.
Stratolaunch completed two flights of its autonomous Talon-A2 rocket plane earlier this year, as the US aims to gain ground in its race for hypersonic supremacy with China.

This is the first time anyone in the United States has flown a reusable hypersonic rocket plane since the last flight of the X-15, the iconic rocket-powered aircraft that pushed the envelope of high-altitude, high-speed flight 60 years ago.
The first production satellites for Amazon's Kuiper broadband network launched earlier this week, but if you tuned in to the mission's official livestream, the truncated coverage had the feel of a spy satellite launch.
This changed with a video Amazon posted on social media Friday, giving space enthusiasts and prospective Kuiper customers their first look at the real satellites. The 40-second clip shows the Kuiper satellites separating from their launch vehicle in the blackness of space following liftoff Monday from Cape Canaveral Space Force Station, Florida.
Since Amazon unveiled Project Kuiper in 2019, officials at the retail giant have been shy about showing even the most basic imagery of their satellites. Images released by Amazon previously provided glimpses inside the company's satellite factory near Seattle, along with views of the shipping containers Amazon uses to transport spacecraft from Washington to their launch base in Florida.
NASA's Psyche spacecraft, located nearly 150 million miles from Earth on the way to an unexplored metal asteroid, has stopped firing its engines after detecting a problem in its propulsion system.
NASA published an update Tuesday revealing that the robotic spacecraft shut off its plasma thrusters earlier this month. The news wasn't widely shared until Wednesday, when NASA science chief Nicky Fox posted it on X.
"Engineers with NASA’s Psyche mission are working to determine what caused a recent decrease in fuel pressure in the spacecraft’s propulsion system," the agency said. The spacecraft detected the drop in pressure April 1 inside the line that feeds xenon fuel to the spacecraft's four plasma thrusters.
A couple of weeks ago, ground teams at NASA's Kennedy Space Center in Florida removed one of the four main engines from the Space Launch System rocket slated to send four astronauts on a voyage around the Moon next year.
NASA officials ordered the removal of one of the massive rocket's RS-25 main engines after discovering a hydraulic leak on the engine's main oxidizer valve actuator, which controls the flow of super-cold liquid oxygen propellant into the engine's main combustion chamber, an agency spokesperson told Ars.
In its place, technicians installed another RS-25 engine from NASA's inventory to the bottom of the rocket's core stage, which is standing vertical on its mobile launch platform inside the cavernous Vehicle Assembly Building at Kennedy. Teams began integrating the replacement engine with the rocket last Friday and are in the process of firmly securing it in the Engine 4 position on the core stage, the NASA spokesperson said.
Firefly Aerospace launched its two-stage Alpha rocket from California early Tuesday, but something went wrong about two-and-a-half minutes into the flight, rendering the rocket unable to deploy an experimental satellite into orbit for Lockheed Martin.
The Alpha rocket took off from Vandenberg Space Force Base about 140 miles northwest of Los Angeles at 6:37 am PDT (9:37 am EDT; 13:37 UTC), one day after Firefly called off a launch attempt due to a technical problem with ground support equipment.
Everything appeared to go well with the rocket's first-stage booster, powered by four kerosene-fueled Reaver engines, as the launcher ascended through fog and arced on a southerly trajectory over the Pacific Ocean. The booster stage jettisoned from Alpha's upper stage two-and-a-half minutes after liftoff, and that's when things went awry.
The first 27 operational satellites for Amazon's Kuiper broadband network lifted off from Florida's Space Coast on Monday evening, the opening salvo in a challenge to SpaceX's dominant Starlink global Internet service.
Amazon's Project Kuiper, costing up to $20 billion, will beam high-speed, low-latency broadband signals to consumers around the world. Monday's milestone launch kicks off a test campaign in low-Earth orbit to verify the functionality and performance of Amazon's satellites. In a statement earlier this month, Amazon said it planned to begin providing service to customers later this year.
These initial services are likely to have limited reach. Amazon needs more than 80 launches to complete the first-generation Kuiper network, and this will probably take several years.
The US military launched a long-range hypersonic missile Friday morning from Cape Canaveral Space Force Station in Florida on a test flight that, if successful, could pave the way for the weapon's operational deployment later this year.
The Army's Long-Range Hypersonic Weapon fired out of a canister on a road-mobile trailer shortly after sunrise on Florida's Space Coast, then headed east over the Atlantic Ocean propelled by a solid-fueled rocket booster. Local residents shared images of the launch on social media.
Designed for conventional munitions, the new missile is poised to become the first ground-based hypersonic weapon fielded by the US military. Russia has used hypersonic missiles in combat against Ukraine. China has "the world's leading hypersonic missile arsenal," according to a recent Pentagon report on Chinese military power. After a successful test flight from Cape Canaveral last year, the long-range hypersonic weapon (LRHW)—officially named "Dark Eagle" by the Army earlier this week—will give the United States the ability to strike targets with little or no warning.
Welcome to Edition 7.41 of the Rocket Report! NASA and its contractors at Kennedy Space Center in Florida continue building a new mobile launch tower for the Space Launch System Block 1B rocket, a taller, upgraded version of the SLS rocket being used for the agency's initial Artemis lunar missions. Workers stacked another segment of the tower a couple of weeks ago, and the structure is inching closer to its full height of 355 feet (108 meters). But this is just the start. Once the tower is fully assembled, it must be outfitted with miles of cabling, tubing, and piping and then be tested before it can support an SLS launch campaign. Last year, NASA's inspector general projected the tower won't be ready for a launch until the spring of 2029, and its costs could reach $2.7 billion. The good news, if you can call it that, is that there probably won't be an SLS Block 1B rocket that needs to use it in 2029, whether it's due to delays or cancellation.

Fresh details on Astra's strategic pivot. Astra, the once high-flying rocket startup that crashed back to Earth with investors before going private last year, has unveiled new details about its $44 million contract with the Department of Defense, Space News reports. The DOD contract announced last year supports the development of Rocket 4, a two-stage, mobile launch vehicle with ambitions to deliver cargo across the globe in under an hour. While Astra's ill-fated Rocket 3 focused on launching small satellites into low-Earth orbit, Astra wants to make Rocket 4 a military utility vehicle. Rocket 4 will still be able to loft conventional satellites, but Astra's most lucrative contract for the new launch vehicle involves using the rocket for precise point-to-point delivery of up to 1,300 pounds (590 kilograms) of supplies from orbit via specialized reentry vehicles. The military has shown interest in developing a rocket-based rapid global cargo delivery system for several years, and it has a contract with SpaceX to study how the much larger Starship rocket could do a similar job.
In an era of reusable rockets and near-daily access to space, NASA is still paying more than it did 30 years ago to launch missions into orbit, according to a study soon to be published in the scientific journal Acta Astronautica.
Launch is becoming more routine. Every few days, SpaceX is sending another batch of Starlink Internet satellites to orbit, and other kinds of missions fill up the rest of SpaceX's launch schedule. SpaceX, alone, has ample capacity to launch the handful of science missions NASA puts into space each year. If supply outpaces demand, shouldn't prices go down?
It's not so simple. NASA is one of many customers jockeying for a slot on SpaceX's launch manifest. The US military is launching more missions than ever before, and SpaceX is about to become the Pentagon's top launch provider. SpaceX already launches more missions for NASA than any other rocket company.
For a quarter-century, dating back to my time as a budding space enthusiast, I've watched with a keen eye each time people have ventured into space.
That's 162 human spaceflight missions since the beginning of 2000, ranging from Space Shuttle flights to Russian Soyuz missions, Chinese astronauts' first forays into orbit, and commercial expeditions on SpaceX's Dragon capsule. Yes, I'm also counting privately funded suborbital hops launched by Blue Origin and Virgin Galactic.
Last week, Jeff Bezos' Blue Origin captured headlines—though not purely positive—with the launch of six women, including pop star Katy Perry, to an altitude of 66 miles (106 kilometers). The capsule returned to the ground 10 minutes and 21 seconds later. It was the first all-female flight to space since Russian cosmonaut Valentina Tereshkova's solo mission in 1963.

Last week, the first operational satellites for Amazon's Project Kuiper broadband network were minutes from launch at Cape Canaveral Space Force Station, Florida.
These spacecraft, buttoned up on top of a United Launch Alliance Atlas V rocket, are the first of more than 3,200 mass-produced satellites Amazon plans to launch over the rest of the decade to deploy the first direct US competitor to SpaceX's Starlink Internet network.
However, as is often the case on Florida's Space Coast, bad weather prevented the satellites from launching April 9. No big deal, right? Anyone who pays close attention to the launch industry knows delays are part of the business. A broken component on the rocket, a summertime thunderstorm, or high winds can thwart a launch attempt. Launch companies know this, and the answer is usually to try again the next day.
