A former NASA engineer claims a new engine can beat gravity without fuel. Is it a breakthrough or just a classic physics trap ...

A salt used to create a green rocket fuel is known to decompose metals—such as those in metal propellant storage tanks. Recent research at the University of Illinois Urbana-Champaign found that there ...

Boeing has plans for a space gas station which would allow up to 15 times more payload to be sent to the moon in some missions. The system would allow for two to three times more payload for many ...

For as long as rockets have existed, motion in space has come with a brutal tradeoff. To move forward, you throw mass ...

Researchers are developing a new type of rocket propellant made of a frozen mixture of water and "nanoscale aluminum" powder that is more environmentally friendly than conventional propellants and ...

One of the most expensive parts of any rocket launch is getting the rocket off the ground and into space. This part of the mission takes a massive amount of fuel and money to pull off. That's why ...

A new propulsion system feeds the same "monopropellant" fuel into electrical and chemical thrusters, potentially saving on ...

In a new paper published in the Journal of Propulsion and Power, the researchers show that this propellant can also power tiny electrospray thrusters. The MIT team is working with NASA to launch a ...

In 2015, NASA, for the first time, will fly a space mission utilizing a radically different propellant—one which has reduced toxicity and is environmentally benign. This energetic ionic liquid, or EIL ...

NASA has put out the call for greener propellant fuel for use on the spacecraft of the future. Though it does not appear that NASA has stipulated that alternative propellants must match the ...
