Yuri's Night

Happy Yuri's Night, everybody! On this night we celebrate the first man in space (Yuri Gagarin in a Vostok capsule, April 12, 1961), the first Space Shuttle flight (Columbia, April 12, 1981), and earlier today Virgin Galactic did an in-flight, cold-flow drop test of SpaceShip Two. Hopefully this will lead up to their first powered flight in a few weeks!
