An international team of engineers and space scientists has used a variety of assumptions, techniques, and math principles to ...

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

The video itself is a reaction to some college students in Utah who caused an evacuation when the rocket fuel they were cooking up exploded. [Scott] himself theorizes that the fuel they were ...

and even hybrid rocket engines are becoming passé. We’ve never seen a liquid-fuel rocket build before, so that’s what this roundup evolved into. First up is [Robert Watzlavick], who has been ...

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 ...

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

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 ...

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

After lift-off, the rocket quickly burns through its fuel. Once the tanks are empty, they break away from the rest of the rocket and fall back to Earth. When the astronauts reach the ISS ...

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 ...

While this latest test doesn’t make nuclear-powered rocket engines viable just yet, it’s an important step on the journey. This latest batch of tests was conducted at the compact fuel element ...
