Modern spaceflight rests on a deceptively simple idea: a machine that carries its own fuel and oxidizer, then hurls exhaust backward fast enough to push itself forward. The person who first turned ...

A nuclear thermal propulsion engine could cut the travel time in half for future space explorers racing to the Red Planet.

The Earth is much larger than most people realize. You need to use engines if you want to efficiently navigate large sections of the planet. Everything from cars to planes relies on engines, but they ...

A new type of rocket engine that could improve aircraft, spacecraft, and other transportation systems is being developed by private and public institutions such as NASA and the Air Force Research ...

There never was a better time to do business in space exploration. One needs to look no further than the many space startups presently operating in this industry to realize that's so. Another proof of ...

A US-based propulsion company has successfully launched and flown a new rocket powered by a unique rotating detonation engine. Although relatively small by rocket standards, the test could pave the ...

SpaceX currently controls nearly every rocket launch on Earth. With 98% of global orbital launches under its belt, Elon Musk's company has become the de facto gatekeeper to space. While China is still ...

The rise of the commercial space industry precipitated a steeper decline at Rocketdyne. Boeing sold the Rocketdyne division ...

When most people think of rockets, they likely imagine something like SpaceX's Raptor engine, or they might recall the Apollo 11 Saturn V rocket that took astronauts to the Moon. Rockets aren't ...
