An Extra Vehicular Activity (EVA) is a whole of activities performed outside a spacecraft by an astronaut wearing a spacesuit. Activities include those after landing on planets or satellites, as well as spacewalks. At the Mission of Apollo 11, for example, there were two categories of EVA. On the one hand, several exits made on the Moon surface by two astronauts from the Lunar Module, including Moonwalk. On the other hand, the "trans-lunar" activity made during the return to the Earth by the pilot of the Commande and Service Module (Columbia) to get photographic shots back. These were automatically taken from the lunar orbit.
