Every year, companies and space agencies launch hundreds of rockets into space—and that number is set to grow dramatically ...

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 ...

President Trump’s plan to deploy a small modular reactor on the moon by 2030 aims to power lunar bases and secure U.S. dominance in space, but faces significant technical and budgetary hurdles. The ...

Scientists have developed a new form of nuclear propulsion that they claim could slash mission times to Mars and enable voyages to the farthest reaches of the solar system. A team from Ohio State ...

Viewed from orbit, Jackass Flats — situated in southern Nevada about 65 miles northwest of Las Vegas — could easily be confused for Mars. The alluvial basin is full of tan and gray regolith, hued ...

New details of the Trump administration’s plans for NASA, released Friday, revealed the White House’s desire to end the development of an experimental nuclear thermal rocket engine that could have ...
