Former SpaceX engineer, Halen Mattison, and his startup, General Galactic, are looking to revolutionize rocket propulsion by turning water into rocket fuel. Their ambitious project, discussed in detail by Wired,

A former SpaceX engineer says he has solved the long-standing engineering problems that have kept water-based rocket propulsion from scaling beyond small satellites. The claim arrives against a backdrop of real,

He's got a lot to prove. The post SpaceX Veteran Says He’s Figured Out How to Make Rocket Fuel From Water appeared first on Futurism.

It's difficult to imagine a substance that is hundreds of degrees below freezing yet still a liquid. Such is the strange nature of the liquid hydrogen and liquid oxygen that are the components of rocket fuel.

Liquid hydrogen fuel leaks forced NASA to delay the launch of Artemis II—the same scenario it encountered four years ago during the Artemis I mission.

Chinese astronauts claim to have created rocket fuel on board the country’s Tiangong space station using a new process dubbed “artificial photosynthesis.” As the South China Morning Post reports, space travelers from the current Shenzhou-19 mission ...

General Galactic, cofounded by a former SpaceX engineer, plans to test its water-based propellant this fall. If successful, it could help usher in a new era of space travel. That's a big “if.”

The best, in fact, the only, candidate for this is the Nuclear Thermal Propulsion (NTP) system or nuclear rocket. First conceived of in 1945, this is a rocket that replaces burning chemical fuel with a nuclear reactor that is used to heat up a propellant. This propellant is most likely hydrogen, though anything could be used, including water.
