Dr. Charles Buhler, a veteran NASA engineer and co-founder of Exodus Propulsion Technologies, has revealed a startling breakthrough. His team’s propellantless propulsion drive has successfully ...

Here’s how it works: Essentially, the rocket has to make thrust – that is, create force – by burning propellant to make hot gases. Then it shoots those hot gases out of a nozzle. It’s sort ...

The reliable operation of rocket combustion chambers under these extreme thermal ... decisive criteria for the further development of space transportation systems. The thrust chamber technology ...

A video (top) shows the Ariane 6, which is similar to SpaceX’s workhorse Falcon 9 rocket in terms of launch thrust, leaving the launchpad on Thursday. The footage also captures other crucial ...

“We're investigating using detonation as an alternative type of rocket combustion and studying whether we can sustain it to create enough thrust for spacecraft with an engine that is compact and ...

UK startup Pulsar Fusion just revealed a nuclear fusion-powered rocket that could halve travel time across the solar system. The spacecraft, called ‘Sunbird’, is designed to remain in orbit for quick ...

Video showed the upper stage of the most powerful rocket ever built spinning out of control in space, a repeat of an unsuccessful test flight in January that led to debris falling over the Caribbean.

SpaceX also altered the propellant temperatures and thrust levels of the engines to avoid a repeat of the leaks. For the rocket on this flight, SpaceX also added more vents to the attic section ...
