NASA (National Aeronautics and Space Administration) uploaded this new video today, a celebration of astronaut Alan B. Shepard's spaceflight -- America's first.
Mercury-Redstone 3 "Freedom 7" launched 60 years ago today and its success was celebrated the world over, partly because the mission was broadcast/televised live, and not done in secrecy (Yuri Gagarin's Vostok 1 flight a few weeks earlier).
