The sprayed rocket propellant landed on a very hot rocket engine, creating flammable vapors. The fire was not seen earlier as the oxygen to cause the reaction is non-existent high up in the ...

This is a compact nuclear fusion engine that provides thrust and power. According to the information available on Pulsar Fusion’s website, DDFD provides a specific impulse of 10,000–15,000 s ...

The unmanned rocket managed to leave its Texas launch ... Flight 7's failure to a propellant leak in one of the ship's Raptor engines that caused "flashes" roughly two minutes into the flight.

Several of Ship's six Raptor engines conked out toward the end of ... Breaking space news, the latest updates on rocket launches, skywatching events and more! Spectators in the Bahamas spotted ...

But minutes later, SpaceX's live stream showed the Starship upper stage spinning in space, while a visualisation of the rocket's engines showed multiple engines shut down before the company ...

More recently, the company started developing two other products in parallel: a Hall-effect electric thruster for spacecraft and a second-stage hybrid rocket engine. “Pulsar has built a ...

But on the Flight 8 launch preparation, they talked about saving 1 metric ton of mass per Raptor 3 engine. This must be mass beyond the engine to related components simplifications. This means about ...

The conversation with Bruno focuses on the development of the Vulcan rocket and its strategic importance. Bruno recounts the initial decision to move away from Russian RD-180 engines due to ...
