I’ve grown up with rockets that burn chemical fuel, but NASA’s next big leap in propulsion could make those engines look as dated as steam trains. By turning to nuclear power in space, the agency is ...

There has been only one mission of the Artemis program to date, an uncrewed test flight of the Orion spacecraft that was conducted back in 2022. Judging this solely from this perspective, you could be ...

NASA engineers have completed first cold-flow tests of a full-scale nuclear thermal propulsion reactor, validating designs for future deep-space missions.

A water system activation at the Thad Cochran Test Stand (B-2) on Jan. 30 at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, helped capture critical data to support testing a new SLS ...

NASA Artemis 2 mission after encountering hydrogen leaks during a fueling test of the Space Launch System. The Space Launch ...

Plasma propulsion transforms an inert propellant – often hydrogen – into plasma, a superheated mix of ions and electrons.

The rehearsal, scheduled to run through early February 3, is meant to stress-test both machines and humans behind NASA’s ambitious return to deep space exploration.
