Since the 1950s rocket engineers have toyed with the idea of a novel engine design that could –- in theory –- revolutionize the way we conceive of space travel. The aerospike might sound like a ...

Ten years ago, NASA launched the first test flights of solid-fuelled rockets with aerospike nozzles. These inside-out rocket engines trade bell-shaped exhaust manifolds for a narrow spike, building ...

Sending rockets to the Moon, Mars, and beyond with humans on board boils down to essentially one thing: being capable of sending with them enough supplies to ensure survival. And that can only be done ...

For decades, an engine concept known as aerospike has been an elusive rival to the traditional bell-nozzle rocket. Although capable of delivering higher payloads while decreasing overall rocket weight ...

Rocket engines are great for producing thrust from fire and fury, but they’re also difficult to make. They require high-strength materials that can withstand the high temperatures involved. [Integza], ...

The aerospike engine—which uses air pressure to shape the downward force needed to launch a spacecraft—has been on the cusp of entering mainstream rocketry for decades. Now, a new company called Leap ...

Showing how far AI engineering has come, a new aerospike engine burning oxygen and kerosene capable of 1,100 lb (5,000 N) of thrust has successfully been hot-fired for 11 seconds. It was designed from ...
