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 ...

there’s more than enough info on his site to try and recreate some of his experiments, but perhaps you should start here instead: How to Design, Build and Test Small Liquid-Fuel Rocket Engines.

Engineers developed an engine prototype which could reach unprecedented speeds, cutting down interplanetary travel time.

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

The Apollo 11 astronauts used advanced technology to land on the Moon. The Saturn V rocket was the largest rocket ever at that point — although SpaceX's Starship topped it when it took flight in ...

Their big trouble is that they are harder to control than liquid-fuel rockets, whose small combustion chambers ... tested only in an experimental rocket engine on the ground.

Most liquid-fuel rocket engines require a secondary combustion chamber to which some fuel is diverted; the exhaust gas is shot through a turbine to pump fuel and oxygen into the main chamber.

and rocket engines from small thrusters to a gigantic F-1 motor from the Saturn V Moon rocket. National Air and Space Museum Rocket, Liquid Fuel, R.H. Goddard 1935, A-Series National Air and Space ...

Elon Musk’s SpaceX suspects a fire is to blame for his 400-foot-tall Starship imploding in space after launching from Texas — sending trails of flaming debris raining down near the Caribbean.

This liquid rocket fuel becomes magnetised when near a magnetic field. So it dances and morphs when magnets are moved around it. It is called ferrofluid and it was invented by NASA's Steve Papell ...

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 ...
