Nasa Invests In A New Solar Sail Concept That Could Propel A Mission To The Sun
Much like how a sailboat uses the wind to move forward, solar sails use the pressure exerted by sunlight to propel a vehicle through space. Large sails made up of reflective material like Mylar capture the momentum of the Sun’s photons. The photons bounce off the sail, sending it in the opposite direction. Also: NASA’s Mars lander is running out of power. Here’s what happens next However, as NASA points out, existing solar sail designs rely on very large and very thin sails....
