July 13, 1969: Luna 15 launches

On July 13, 1969, the Soviet Union sent Luna 15 into space, aiming to beat the upcoming American Apollo 11 mission to the Moon. This unmanned craft was designed to land on the lunar surface, gather rock samples, and return to Earth before the Apollo astronauts could even set foot on the Moon. The intense race between the two superpowers added significant tension to the Space Race, highlighting the technological and ideological stakes of the era. Luna 15 ultimately crashed on the Moon after its mission failed, but its launch marked a pivotal moment in human space exploration history.
