A nuclear thermal rocket engine in development could one day transport humans to Mars. The Defense Advanced Research Projects Agency, a research arm of the US Department of Defense, and NASA are ...

There have been full scale nuclear thermal rocket engines built and tested on the ground since the 1960s. The US had the NERVA project. The attraction is that the ISP would be up to triple the ISP of ...

LMT's DRACO project cut by budget slashes, but its deep NASA ties and NEP work keep its space ambitions alive.

Angry Astronaut describes a hypothetical nuclear thermal rocket assembled in orbit. He assumes a nuclear thermal rocket will be working by the end of 2030. He says the SpaceX approach to building a ...

Engineers say a nuclear thermal rocket could cut astronauts' travel time to Mars from nine months to two. Credit: NASA NASA and the U.S. military plan to test a nuclear-powered rocket engine in ...

NASA's initiatives to pioneer next-generation space technologies are also hit hard in the White House's budget proposal. If the Trump administration gets its way, NASA's Space Technology Mission ...

Nuclear thermal propulsion systems have roughly twice the specific impulse of chemical rockets, which means they could cut the travel time by a factor of 2. Nuclear thermal propulsion history ...

Nuclear thermal propulsion could also one day power maneuverable space platforms that would protect American satellites in and beyond Earth's orbit. But the technology is still in development.

Nuclear thermal propulsion (NTP) has stood as a promising potential alternative propulsion technology for decades. Chemical rockets have begun to reach their theoretical maximum efficiency, and ...

Nuclear thermal propulsion could also one day power maneuverable space platforms that would protect American satellites in and beyond Earth's orbit. But the technology is still in development.

Recent advancements in nuclear thermal propulsion (NTP) technology could make future human missions to Mars significantly faster, potentially cutting the travel time in half compared to ...

We’re building nuclear spaceships again—this time for real The military and NASA seem serious about building demonstration hardware.
