Nuclear thermal rockets could be more manoeuvrable in space
The US is taking steps to put a nuclear-powered rocket in orbit by 2025, paving the way for navigation in space to become much easier.
The Defense Advanced Research Projects Agency (DARPA) plans to turn the long-studied concept of a nuclear thermal rocket into a reality. The technology isn’t powerful enough to launch a rocket from Earth, but could give a spacecraft propulsion for an extended period once in space. This would make it ideal for prolonged manoeuvring in orbit or in deep-space missions requiring acceleration and deceleration.
