Every year, companies and space agencies launch hundreds of rockets into space—and that number is set to grow dramatically with ambitious missions to the moon, Mars and beyond. But these dreams hinge ...

If we achieve advanced nuclear, antimatter propulsion or other advance propulsion it would be possible to achieve near constant acceleration. This would enable travel times to Mars in the 3-8 day ...

I’ve grown up with rockets that burn chemical fuel, but NASA’s next big leap in propulsion could make those engines look as ...

Portal Systems' new Supernova satellite will use sunlight and a special 3D printed thruster to heat ammonia to propel itself ...

Nuclear rockets are the future of space propulsion, and while fission propulsion is rapidly developing, most believe fusion propulsion is still a ways off. However, a new U.K.-based company is ...

It seems too good to be true, but UK-based Pulsar Fusion has revealed its new Sunbird self-contained nuclear rocket tug that uses a fusion propulsion engine that could reduce a trip to Mars to under ...

WASHINGTON — Quantum Space is acquiring propulsion technologies and facilities from Phase Four to support development of its Ranger maneuverable spacecraft. The company announced Sept. 22 it acquired ...

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 ...

With the Artemis Moon exploration program that'll bring humans back to the satellite surface now its way, NASA is planning to play seriously this time. It will not go there just to visit, but to stay ...

Space is becoming more crowded and as the number of satellites increases, so too does the risk of a collision, highlighting the need for multimode propulsion in spacecraft, according to industry ...

A handful of Senate Republicans are wrestling with the impending expiration of health insurance subsidies that are the primary sticking point in the government shutdown standoff that entered its 13th ...
