NASA’s New Solar Sail Has Launched and Will Soon Deploy

Electron launch

Solar Sails are an enigmatic and majestic way to travel across the gulf of space. Drawing an analogy to the sail ships of the past, they are one of the most efficient ways of propelling craft in space. On Tuesday a RocketLab Electron rocket launched NASA’s new Advanced Composite Solar Sail System. It aims to test the deployment of large solar sails in low-earth orbit and on Wednesday, NASA confirmed everything is looking good for sail deployment

Mercury is the Perfect Destination for a Solar Sail

Solar sails rely upon pressure exerted by sunlight on large surfaces. Get the sail closer to the Sun and not surprisingly efficiency increases. A proposed new mission called Mercury Scout aims to take advantage of this to explore Mercury. The mission will map the Mercurian surface down to a resolution of 1 meter and, using the highly reflective sail surface to illuminate shadowed craters, could hunt for water deposits.
