NASA is working on a lithium-plasma electric thruster that uses roughly 90% less fuel than chemical rockets. Can this new technology help us colonize Mars?

While NASA pushes forward with its nuclear-powered engine concepts and researchers hunt for clever orbital shortcuts to slash ...

NASA's Jet Propulsion Laboratory recently reached a significant achievement in space travel technology. They successfully tested a lithium-fed magneto.

Russia is quietly testing a new plasma propulsion system that, if it performs as claimed, could dramatically change how long it takes to travel to Mars. Early results suggest a leap in speed and ...

Space has a trash problem, with defunct satellites, rockets, and smaller broken bits orbiting Earth at high speeds. The amount of space junk is only increasing, raising the risk of collision with ...

NASA’s new electric propulsion engine set a U.S. power record and could transform future Mars missions. The thrusters use ...
