In the 50 years that NASA has been in the space game, it has scored a long string of triumphs in spaceflight and the exploration of distant worlds and the cosmos. No less impressive is NASA’s record of wins for the home team: planet Earth and all of us living on it. With a strong roster of globe-circling satellites, flying labs, advanced computing, and scientists and engineers, NASA has led the way in seeing a whole new Earth and understanding our responsibility for its future.
