| Video Discription | The story of Znamya- the Russian space mirror and how it turned night into day . It may sound like a plan only a supervillain could imagine, but during the 1990s, a group of Russian scientists and engineers devised a gadget that redirected sunlight lost to space back to Earth. A consortium of state-owned companies and agencies in Russia, headed by the NPO Energia space company, sponsored the mirror-solar sail demonstration. The idea of using mirrors in space like giant spotlights was proposed in 1929 by Hermann Oberth, a German scientist and space visionary. Although both the Pentagon and the National Aeronautics and Space Administration (NASA) in the USA considered solar reflector constructs from time to time in the last two decades, they never developed them due to budget constraints and lack of confidence. Using reflectors 650 feet in diameter, initial operational systems were planned to have 24 to 36 mirrors in northern inclination orbits either 620 miles or 3,700 miles above Earth, proponents say. Syromyatnikov might have made his name with docking mechanisms, but in the late 1980s, his passion project was developing solar sails that could propel spacecraft through the stars by riding the stars' radiation pressure like ship sails in the wind. Even after the fall of the Soviet Union, Syromyatnikov continued to work on the project, and in 1993 he got his chance to put Znamya to the test. Funded by a collection of Russian state-owned corporations, Syromyatnikov constructed a 65-foot-wide sheet of mylar that could be deployed from a central mechanism and launched from the Mir space station. The initial plan was to have the Progress spacecraft carry the 88-pound Banner experiment as a secondary payload docked with the Mir space station. After visiting the EO-12 crew aboard the Mir space station, the Progress T-15 then undocked and deployed the reflector from the end of the Russian Progress spacecraft on 4 February 1993, next to the Russian Mir space station. The mirror deployed successfully and, when illuminated, produced a 5 km wide bright spot, which traversed Europe from southern France to western Russia at a speed of 8 km/h. Reception back at base by the Russian Federal Space Agency was jubilant and optimistic and plans were worked up to create successors even though the prototype fell short of initial expectations. --------------------- Welcome to Futurephile .
