That's why rockets have to carry tanks of both fuel and oxidizer. The SpaceX Falcon 9's Merlin engines use rocket-grade kerosene (RP-1) fuel with liquid oxygen as the oxidizer.

Goddard's work offered an exponential leap in rocket technology, as he hoped they could carry people into the upper atmosphere. His rockets didn't make it too far into the sky, with the highest ...

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 ...

Work to develop a reusable engine for European rockets is progressing, with full ignition of an early prototype of Prometheus.

NASA will test the engine’s powerpack, a gas generator and turbopumps that perform the rocket engine’s major pumping and combustion work.

The engines are of the full-flow, staged-combustion (FFSC) variety that work pretty much the same way the Raptor engines in SpaceX rockets do.

Back-to-back engine failures doomed a privately developed Australian rocket moments after liftoff Tuesday, cutting short a long-shot attempt to reach orbit with the country's first homegrown launch ...

Space startup Rocket Lab performed the first hot fire test on a new rocket engine called Archimedes, nine of them will power next year's Neutron rocket.

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 ...

Houston-based Venus Aerospace flew a rotating detonation rocket engine last week, proving a key technology for the high-speed plane it's developing to fly from Los Angeles to Tokyo in two hours.
