Less than two years after the successful launch of Sputnik 1, the Soviet Union put a spacecraft on the Moon. Launched Sept. 12, 1959, Luna 2 traveled over 30 hours to crash-land on the lunar surface. The impact happened at a speed of about 1.9 miles (3 kilometers) per second, and represented the first contact between a human-made craft and a solar system body other than Earth. Though the impact destroyed the spacecraft, its suite of instruments returned data before the crash, and helped confirm that the Moon lacks both significant magnetic field and radiation belts like Earth’s Van Allen belts. And, of course, the political weight of Luna 2 represented another Soviet win in the Space Race.
