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 ...

Who needs the laws of physics, anyway? Not NASA. At least, that is what a new peer-reviewed paper indicates. The paper discusses what was a fuel-free rocket engine, which tests now show works. But how ...

NASA’s push for a new nuclear rocket engine is not just another upgrade to the hardware we strap to the bottom of spacecraft. It is an attempt to rewrite the basic rules of how far, how fast, and how ...

In the relentless quest to make journeys to Mars shorter and safer, Russian scientists have recently turned heads with a bold claim: A plasma-based propulsion system could cut the Earth–Mars transit ...

There have been published papers by the Air Force Research Lab and NASA on rotating detonation engines having 10% or more efficiency gains. A rotating detonation engine (RDE) uses a form of pressure ...

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.

Using supersonic shockwaves for combustion, the groundbreaking design could allow aircraft to travel up to six times the speed of sound. Reading time 4 minutes Venus Aerospace is a winner of the 2025 ...

SpaceX has shared dramatic slow-motion footage showing a Raptor engine powering down at the end of a recent test fire. “Shutdown of a Raptor vacuum engine in slow motion,” SpaceX said in a message ...

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 ...

The students traipsed down into the depths of the quarry on a frigid night in February 2020 to fire their liquid-fuelled rocket engine. It was an ambitious goal, less generously characterized as ...

Firefly Aerospace launched its two-stage Alpha rocket from California early Tuesday, but something went wrong about two-and-a-half minutes into the flight, rendering the rocket unable to deploy an ...
