Steering by the Stars
June 16, 1970
Overview
Patrick Moore examines some instruments used by ancient mariners to steer their ships by the stars, and discusses with James Burke the use of the stars by American astronauts and scientists to navigate the Apollo and Mariner Mars Spacecraft. The emergency return of Apollo 13 and the fact that Mariner 7 was 'locked on' to the wrong star presented the navigators with an extraordinary set of problems. As man ventures further into space Steering by the Stars will become more and more important.
