The Mission

On April 11, 1970, three astronautsβ€”Jim Lovell, Jack Swigert, and Fred Haiseβ€”launched aboard Apollo 13 with one goal: land on the Moon and return safely to Earth. 56 hours in, an oxygen tank exploded 200,000 miles from Earth. The lunar landing was abandoned. The new mission: survive and return home.
