Researchers have proposed a new propulsion method that could ... so to get a given amount of energy from a beam, you either need very high power or you need to stay in the beam a long time." ...

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 ...

By focusing this energy into a relativistic electron beam, the statite could propel a spacecraft over distances of 100 to 1,000 AU. This represents a significant leap over existing propulsion ...

Sunbeam’s calculations show it could propel probes up to 1,000 AU from Earth, far outlasting traditional laser propulsion methods. A 1,000 kg probe powered ... such a beam requires up to 19 ...

Researchers have proposed a new propulsion method that could make ... where the intense sunlight could provide the power needed for the beam. "While there is engineering work to do in making ...
