AI gives a thumbs up to Brett Bellmore innovative modifications to Robert Zubrin’s Nuclear Salt Water Rocket (NSWR).

To prepare the rocket's RS-68A engines, very cold cryogenic hydrogen propellant flows into them before they ignite. "Hydrogen is lighter than air, so after it flows through the engine and the ...

Developed by Rosatom’s Troitsk Institute, the new technology could drastically reduce current space travel durations, which ...

Rocket thrusters powered by the hydrogen and oxygen in water do exist, and while NASA succeeded with using this kind of propulsion system to launch their PTD-1 CubeSat in 2021, water fuel has not ...

We are at a critical time and supporting climate journalism is more important than ever. Science News and our parent organization, the Society for Science, need your help to strengthen ...

The resulting water would then be split to feed the hydrogen back into the system, while the oxygen can be sent off for use in rockets. (This wouldn't solve the issue of what that oxygen will ...

Thus, to produce rocket fuel, the oxygen would have to be ... one that involves purifying ilmenite and then combining it with hydrogen (which could be obtained from water on the moon) at a high ...

Michael Strano set off hydrogen-fueled rockets as a kid. Today his lab is developing nanosensors, bionic plants, nanoscale ice wires, and a brand-new source of energy. If you know of any MIT ...

The goal for Climate Impulse is to take off unassisted, fly some 40,000 kilometers (about 25,000 miles) around Earth along the Equator at a gentle speed of about 200 kilometers per hour (125 mph), and ...
