Eco-friendly alternatives to fossil fuels are venturing beyond Earth—and into space.

We are fascinated by the hybrid rocket engine which [Ben Krasnow] built and tested in his shop. It is actually using a hollow cylinder of acrylic as the fuel, with gaseous oxygen as an oxidizer.

A new test of nuclear propellant fuel under space-like conditions has been hailed as a success by NASA and General Atomics ...

The trials verify that the fuel can survive the harsh environment of a nuclear rocket reactor. Up until now, the main way of propelling spacecraft has been through chemical rockets. To be fair ...

When Germany surrendered to the Allies, the SS ordered that all the books, charts, and records ... involved in inventing a new fuel formulation for the rocket. After the Vanguard failures in ...

NASA and its partners have successfully tested a nuclear thermal propulsion (NTP) fuel that could revolutionize deep-space ..

Breathing New Air Chinese astronauts claim to have created rocket fuel on board the country's Tiangong space station using a ...

For nearly a year, SpaceX has been trying out something new: super-cooling the liquid oxygen (LOX) which is a key ingredient in rocket fuel. It's called deep-cryo LOX, and the idea has been around ...

Space is the only place where rocket fuel could be more precious than water. The China Manned Space Agency announced last month that taikonauts on the ongoing Shenzhou-19 mission successfully ...

The tests showed the fuel can withstand the harsh conditions of a nuclear thermal propulsion reactor. In other words, it has the capability to one day power a nuclear rocket that could fire humans ...
