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 ...

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 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 ...

The sun will begin to die in about 5 billion years when it runs out of hydrogen. We asked physicist Frederick C. Bruhweiler a few frequently asked questions about the death of the sun and what it ...

At that point most American rockets were fuelled by liquid hydrogen, burned with liquid oxygen. Hydrogen is theoretically the best rocket fuel there is, but it’s very difficult to handle safely.

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

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 ...
