"Apollo 13" was the seventh manned mission in the United States/American Apollo program/Apollo space program and the third intended to moon landing/land on the Moon. The craft was launched on April 11, 1970, at 13:13 Central Time Zone (Americas)/CST from the Kennedy Space Center, Florida, but the lunar landing was aborted after an oxygen tank exploded two days later, crippling the Apollo Command/Service Module#Service Module (SM)/Service Module (SM) upon which the Apollo Command/Service Module#Command Module (CM)/Command Module (CM) depended. Despite great hardship caused by limited power, loss of cabin heat, shortage of potable water, and the critical need to Jury rig/jury-rig the carbon dioxide removal system, the crew returned safely to Earth on April 17.

The flight was commanded by Jim Lovell/James A. Lovell with Jack Swigert/John L. "Jack" Swigert as Command Module Pilot and Fred Haise/Fred W. Haise as Lunar Module Pilot. Swigert was a late replacement for the original CM pilot Ken Mattingly, who was grounded by the flight surgeon after exposure to German measles.
