Propellant-less Rockets ... challenges this principle by achieving motion without the need for fuel combustion. "This discovery of a New Force is fundamental in that electric fields alone can ...

The combustion chamber is first precooled by the methane flowing through it. This causes humidity in the air to condense and ice to form on the combustion chamber. The cooling starts in the nozzle ...

However, while boron has been investigated for such applications since the 1940s, this propellant has been difficult to tame due to its variable and complex combustion behaviour. Alla Pivkina ...

SpaceX said Monday that last month’s Starship explosion was brought on by a cascading series of events caused by propellant leaks — a problem the company says has been addressed ahead of an ...

Propellant and oxidizer are mixed in a combustion chamber, creating a mixture of hot gases at high pressure that very much wish to leave out the back of the rocket, generating thrust. However ...

This special property makes it possible for gel propellants to combine the advantages of liquid propellants, such as compact combustion chambers and controllability, with those of solid propellants, ...

WASHINGTON — SpaceX said that a Falcon 9 upper stage that reentered over Europe earlier this week suffered a propellant leak that prevented it from doing a controlled reentry. The upper stage ...

While NASA struggles with helium leaks on its Starliner spacecraft, Chinese researchers have found a novel way to use this gas to improve missile performance. This discovery could revolutionize ...

TANEGASHIMA, Kagoshima Prefecture--Japan’s space agency halted an engine combustion test of its ... an enhanced second-stage motor with propellant increased from 15 tons to 18 tons, which ...
