Honda is looking to the stars for its next hydrogen breakthrough.
The automaker is teaming up with space tech companies Sierra Space and Tec-Masters to test its high-differential pressure water electrolysis system on the International Space Station. The test is part of Honda’s vision to support life on the Moon and elsewhere in space using regenerative fuel cell technology that continuously produces hydrogen, oxygen, and electricity.
It’s another risky move from Honda, which is more bullish on hydrogen than most other automakers. Hydrogen-powered cars have historically faced a lot of hurdles, including fueling challenges and pricing pressures. But Honda is counting on hydrogen to help it decarbonize its vehicle fleet by 2040. And now it wants to tap into the most abundant element in the universe to power its push into space.
Honda says it envisions its hydrogen-powered regenerative system as part of a human settlement on the lunar surface. But it also hopes that by stress testing the technology on the Moon, it can prove its utility on Earth.

Here’s how Honda’s system works: during the lunar day, the system will use electricity generated by solar panels capturing sunlight. The company’s high-differential pressure water electrolysis system will then produce hydrogen and oxygen from water. When the Moon rotates away from the Sun, some of the oxygen will be used for astronauts, with the rest put toward generating electricity. The only byproduct of the electrolysis process is water, which is recycled back into the regenerative system, creating a closed-loop energy cycle.
Honda plans on testing the process in the microgravity environment on the ISS. The company says it will work with NASA to transport the equipment on Sierra Space’s Dream Chaser spaceplane, with Tec-Masters as the ISS technology expert.
Creating a reliable source of oxygen and electricity in space would help humans establish livable habitats off-Earth in an era when space travel seems more achievable than ever. While the science community has explored the use of electrolysis as a means to sustain life in the vacuum of space, it has found that low gravity environments will have some effect on the gas-evolving process. A study published in 2022 concluded that around 11 percent less oxygen was created through electrolysis in a lunar environment as compared to the gravity of Earth.

Welcome to Edition 7.38 of the Rocket Report! SpaceX test fired a Super Heavy booster that launched in January on Thursday, in South Texas. This sets up the possibility of a reused Super Heavy rocket launching within the next several weeks, and would be an important step forward in the Starship launch program. It's also a bold step given that there is a lot riding on this Starship launch, given that the last two have failed due to propulsion issues with the rocket's upper stage.

European commercial launch industry joins the space race. The first flight of Isar Aerospace's Spectrum rocket didn't last long on Sunday, Ars reports. The booster's nine engines switched off as the rocket cartwheeled upside-down and fell a short distance from its Arctic launch pad in Norway, ending the abbreviated test flight with a spectacular, fiery crash into the sea. However, it marked the beginning of something new in Europe as commercial startups begin launching rockets.

When you set up a new camera, or even go to take a picture on some smartphones, youâre presented with a key choice: JPG or RAW?
JPGs are ready to post just about anywhere, while RAWs yield an unfinished file filled with extra data that allows for much richer post-processing. That option for a RAW file (and even the generic name, RAW) has been standardized across the camera industry â but despite that, the camera world has never actually settled on one standardized RAW format.
Most cameras capture RAW files in proprietary formats, like Canonâs CR3, Nikonâs NEF, and Sonyâs ARW. The result is a world of compatibility issues. Photo editing software needs to specifically support not just each manufacturerâs file type but also make changes for each new camera that shoots it. That creates pain for app developers and early camera adopters who want to know that their preferred software will just work.
Adobe tried to solve this problem years ago with a universal RAW format, DNG (Digital Negative), which it open-sourced for anyone to use. A handful of camera manufacturers have since adopted DNG as their RAW format. But the largest names in the space still use their own proprie …
China has responded to Donald Trumpâs new trade tariffs with its own charges on US goods. After Trump announced the imposition of an additional 34 percent charge on Chinese imports into the US, China has announced a levy at the same rate for US goods shipped to China.
It has also barred 11 US companies from trading in the country, applied new restrictions to rare earth mineral exports, filed a lawsuit with the World Trade Organization (WTO), and started investigations into imports of American medical equipment.
In a statement announcing the new tariff, Chinaâs finance ministry declared that the US tariff on Chinese goods âseriously undermines China’s legitimate rights and interests,â and called it a âtypical unilateral bullying practice.â
Trump announced his latest levy on Chinese imports as part of new tariff rates that affect every country the US trades with, including a few uninhabited islands. It followed two separate 10 percent tariffs from earlier in the year, bringing the USâs total tariff on Chinese goods to 54 percent. He also signed an executive order ending the âde minimisâ exemption for packages valued below $800, which could be a death blow for C …
