Teams at pad 39B are currently investigating what caused a serious hydrogen leak during the fueling process on Sept. 3. The massive rocket's liquid oxygen tank reached 100% filled, but hydrogen ...

It’s a relatively new choice for rocket fuel, ... Think of it this way: If methane-and kerosene-powered rockets are space sedans, hydrogen-powered engines are sports cars.

Hydrogen fuel cell power plants for ships face the challenge of hydrogen’s low volumetric energy density at normal temperature ...

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 ...

Cap Marine says it will supply 8 MW of hydrogen fuel cell systems for four zero-emission vessels under construction for ...

(This wouldn't solve the issue of what that oxygen will ultimately oxidize to power a rocket. But oxygen is typically the heavier component of rocket fuel combinations—typically about 80 percent ...

As fuel and oxidiser are burned in the rocket's engines, helium fills the resulting empty space in the tanks, maintaining the overall pressure inside. Because it is non-reactive, it can safely ...
