“During this time another spacecraft, Luna 15 - an unmanned Soviet spacecraft in lunar orbit, began its own descent to the lunar surface. Launched only three days before the Apollo 11 mission, this was the third Soviet attempt to return lunar soil back to Earth. The Russian craft crashed on the moon at 15:50 UT – just a few hours before the scheduled American liftoff.[36] In a race to reach the Moon and return to Earth, the parallel missions of Luna 15 and Apollo 11 were, in many ways, the culmination of the space race that underlay the space programs of both the United States and the Soviet Union in the 1960s. The simultaneous missions became one of the first instances of Soviet/American space cooperation as the USSR released Luna 15's flight plan to ensure it would not collide with Apollo 11, though its exact mission was unknown.[37] ”
