In comparison to 60,000 kilometers per second transit speed, "some kind of orbit" is a dead stop. This would have to dump 99 and a lot more nines worth of its speed in order to stay in the ...

Fuel free interplanetary travel? ‘Photonic crystal’ sail could help laser beams push spacecraft
Researchers from Tuskegee University, Alabama, have developed a new photonic crystal (a kind of ...
For decades, researchers have explored light sails as an alternative. These devices use radiation pressure—the force exerted when light reflects from a surface—to generate thrust. When driven by a ...
Most space missions rely on chemical rockets for propulsion. Rockets must carry fuel, which increases spacecraft mass and limits their speed and travel distance. For decades, researchers have explored ...
Scientists have successfully tested a material design for light sails using photonic crystals that could achieve 20% the speed of light ...
Sailboat racing, and the sailing industry at large, is anything but green despite being a sport powered by wind. Hulls, sails, cordage and most components are largely derived from fossil fuels, and ...
