One promising solution involves transmitting energy or momentum to spacecraft from external sources. These so-called "beamrider" concepts use directed beams of energy or particles to propel a ...

According to a study published in Acta Astronautica, researchers Jeff Greason, Chief Technologist at Electric Sky, Inc, and Gerrit Bruhaug, physicist at Los Alamos National Laboratory, have proposed ...

Lightsails operate by harnessing radiation pressure from a light source, such as the Sun or lasers, to propel a spacecraft.

New propulsion method could achieve interstellar travel within a lifeti Relativistic electron beams could reach 10% of light speed Cost-effective alternative to laser-powered sails for space travel ...

He pointed out that the attainment of relativistic velocities by a rocket-propelled vehicle is hampered ... by the pressure exerted on it by a light beam transmitted from the Earth, then, because ...

Powered by laser light, this tiny sail lays the groundwork for future advances in lightsail technology and the potential for interstellar propulsion.

NASA and General Atomics tested the fuel by exposing it to temperatures up to 3,000 Kelvin (4,940 Fahrenheit or 2,727 Celsius ...

The idea of traveling through interstellar space using spacecraft propelled by ultrathin sails ... and ride stably along the axis of a laser beam," Atwater says. "But before we can begin building ...

Caltech scientists are developing laser-driven lightsails that could push spacecraft beyond our solar system. Their research ...

A small uncrewed spacecraft is buzzing the moon, with under two weeks remaining before its bold attempt to land on the lunar surface. But the real treat was the footage beamed back to mission ...
