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 ...

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 ...

Forward-looking: Scientists have long envisioned nuclear electric propulsion as a transformative technology for unlocking the potential of solar system exploration. Now, two companies making steady ...

Get ready because the future of traveling to other planets just got a massive upgrade. Pulsar Fusion, a U.K.-based aerospace company, is developing a compact fusion engine called the Dual Direct ...

Angry Astronaut and Nextbigfuture commenter are making the case that SpaceX and Elon Musk must switch to nuclear thermal rockets to colonize Mars. I will review that the nuclear thermal rocket program ...
