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 ...

There have been full scale nuclear thermal rocket engines built and tested on the ground since the 1960s. The US had the NERVA project. The attraction is that the ISP would be up to triple the ISP of ...

I’ve grown up with rockets that burn chemical fuel, but NASA’s next big leap in propulsion could make those engines look as dated as steam trains. By turning to nuclear power in space, the agency is ...

The Blue Origin BE-3 rocket engine being test fired at the company's facility in West Texas. Blue Origin, the United Launch Alliance partner developing a next-generation U.S. rocket engine, said this ...

A Texas-based startup just made aviation history. The company completed the first U.S. flight test of a next-generation rocket engine that could be transformational for both hypersonic weaponry and ...

A new type of rocket engine, one that could power a plane from Los Angeles to Tokyo in just two hours, has eluded scientists for decades. Houston’s Venus Aerospace says it recently solved the puzzle.

Rocket technology predates space exploration by almost a thousand years, and although today's computerized multi-ton launch vehicles are a lot more capable than 11th-century gunpowder-assisted arrows, ...

In what may be a world first, Venus Aerospace has, for the first time in the US, successfully flown a Rotating Detonation Rocket Engine (RDRE) that uses supersonic explosions to create thrust. Such ...

Work to develop a reusable engine for European rockets is progressing, with full ignition of an early prototype of Prometheus. These images were taken on 22 June 2023 at ArianeGroup’s test facility in ...

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 ...

It was back in June 2023 when we first got word of a new breed of solid rocket engine being in the works, and here we are less than a year later faced with the prospect of the engine's impending ...
