Mission commander Lovell reported to mission control on Earth: “Houston, we’ve had a problem here,” and it was discovered that the normal supply of oxygen, electricity, light, and water had been disrupted. The landing mission was aborted, and the astronauts and controllers on Earth scrambled to come up with emergency procedures. The crippled spacecraft continued to the moon, circled it, and began a long, cold journey back to Earth.
The astronauts and mission control were faced with enormous logistical problems in stabilizing the spacecraft and its air supply, and providing enough energy to the damaged fuel cells to allow successful reentry into Earth’s atmosphere. Navigation was another problem, and Apollo 13‘s course was repeatedly corrected with dramatic and untested maneuvers. On April 17, with the world anxiously watching, tragedy turned to triumph as the Apollo 13 astronauts touched down safely in the Pacific Ocean.
