"Chemical rockets that we use today, even with the extra speed boost from flying by planets, or from swinging by the sun for a boost, just don't have the ability to scale to useful interstellar speeds ...

Astronauts on board China's "heavenly palace" space station have demonstrated a new way of making rocket fuel products and ...

An electrospray engine applies an electric field to a conductive liquid, generating a high-speed jet of tiny droplets that ...

This relatively long transit time is a result of the use of traditional chemical rocket fuel. An alternative technology to the chemically propelled rockets the agency develops now is called ...

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 ...

The chemical reaction taking place in most rockets has the same constituent elements as a fire—there's fuel, an oxidizer, and an ignition source. The problem with traveling high into the ...

This 3D printing technology could allow astronauts to manufacture satellite engines in space, eliminating the need for Earth-based launches.

Today, rockets heavily rely on chemical propulsion. Deep space probes like Voyager 1 and 2, meanwhile, have used ion propulsion to reach further than any human-made spacecraft. While chemical ...

"Chemical rockets that we use today, even with the extra speed boost from flying by planets, or from […] swinging by the sun for a boost, just don't have the ability to scale to useful ...

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 ...

Today, rockets heavily rely on chemical propulsion. Deep space probes like Voyager 1 and 2, meanwhile, have used ion propulsion to reach further than any human-made spacecraft. While chemical ...

Electric propulsion (EP) thrusters are expected to revolutionize space exploration, offering a fuel-efficient alternative to traditional chemical rockets. "Electric propulsion works by ionizing a ...
