Engineers developed an engine prototype which could reach unprecedented speeds, cutting down interplanetary travel time.

In a Saturn V rocket engine, liquid oxygen and kerosene fuel are pumped separately into the engine at high pressure. They first travel through a pre-burner, which dumps exhaust into the air.

The shape tapers toward the back, ensuring that the exhaust gases flow along its ... In the ’60s, rocket engine design and manufacturing company Rocketdyne had tried to make the J-2T Aerospike ...

Rocket exhaust plume at 30 km as obtained by high-resolution computational fluid dynamics simulations. Temperature varies from 680 K (dark yellow) to 2,400 K (bright yellow). Journalists may use ...
