Jim Bickford is leading the Thin Film Isotope Nuclear Engine Rocket (TFINER) project to develop a system for propelling a craft through space faster and farther than ever before. This technology has ...

Viewed from orbit, Jackass Flats — situated in southern Nevada about 65 miles northwest of Las Vegas — could easily be confused for Mars. The alluvial basin is full of tan and gray regolith, hued ...

AI gives a thumbs up to Brett Bellmore innovative modifications to Robert Zubrin’s Nuclear Salt Water Rocket (NSWR). Switching from water to polyethene and storing in sausage strings could enhance its ...

A new kind of space engine could change how we explore the solar system, and it's powered by the same force that lights up the stars. A British startup called Pulsar Fusion is working on a nuclear ...

NASA is backing a new generation of nuclear rockets that could compress the months-long journey to Mars into a sprint measured in weeks. The most ambitious concepts on the table promise crewed trips ...

The best, in fact, the only, candidate for this is the Nuclear Thermal Propulsion (NTP) system or nuclear rocket. First conceived of in 1945, this is a rocket that replaces burning chemical fuel with ...

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 ...
