This spring two Russian satellites will be orbited with the task of blocking natural disasters and lighting certain spots on the Earth’s surface. They will use the simple method of reflected light from thin-filmed space reflectors, writes Moskovsky Komsomolets. According to Aerospace Systems, thin-filmed reflectors are a kind of a sail made of modern materials that feel like a mixture of foil and cellophane. The most difficult task is to open the 25m sail in space. It is believed that the miracle sail will be able to correct weather, sending reflected light and warming the clouds to ensure good weather for a football match, for example.
