The rocket, a reaction-propulsion device that carries all of its propellants internally, has been around for almost a millennium since its invention in China. But the twentieth-century saw a ...

Electric propulsion is being increasingly used on space missions and could ultimately replace thrusters using chemical rockets. Spacecraft powered by electric propulsion could soon be better ...

A rocket engine based on detonative combustion could therefore theoretically have significantly higher efficiency than today’s engines. This is why interest in detonation engines for both gas turbines ...

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 ...
