![]() | 1965 | Soviet cosmonaut Alexei Leonev makes the first spacewalk outside the Voskhod 2 spacecraft. Although a television camera captures the event, good quality photographs could not be retrieved because the camera became stuck in the airlock, which was jettisoned before re-entry. Leonov later flew on the Apollo-Soyuz mission. |
