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 ...
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 ...
A tiny spacecraft in Earth orbit has successfully deployed its solar sails. Called LightSail 2, the craft will now use the power of the Sun to lift its orbital height even further, in what’s ...
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 ...
