Meteors and meteorites travel around space in their millions. A few reach the earth but most are burnt up in our atmosphere. Astronauts in space suits, moon bases and manned satellites will be unprotected by the atmosphere. Patrick Moore talks about meteors, and the danger they may pose to future astronauts and their equipment with Dr. N. H. Langton, a physicist who has studied this problem.
