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 ...

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

There have been off and on nuclear thermal rockets program since the 1960s. In 2022, DARPA announced its goal of conducting an in-space flight demonstration of nuclear thermal propulsion in 2026. In ...

The US Department of Defense’s (DOD’s) Defense Advanced Research Projects Agency (DARPA) has cancelled the Demonstration ...

A nuclear thermal rocket could potentially achieve double or triple the Delta-V of a SpaceX Starship with just the full orbital refueling. But to move large payloads of 100-200 tons, then the thrust ...

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 ...

As we set our sights on crewed Mars missions, we're going to have to consider some next-level rocket engines. One idea with a lot of potential is nuclear thermal propulsion.

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 ...

Ars Technica has been separating the signal from the noise for over 25 years. With our unique combination of technical savvy and wide-ranging interest in the technological arts and sciences, Ars ...

NASA and the DARPA’s Demonstration Rocket for Agile Cislunar Operations, or DRACO, program intends to use this high-assay, low-enriched uranium fuel in its nuclear thermal propulsion engine. The ...

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 ...
