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 ...

The USA's Defense Advanced Research Projects Agency has finalised an agreement with Lockheed Martin to begin work on the fabrication and design of an experimental nuclear thermal rocket and its engine ...
