context_page_description: Apollo 13 was the seventh crewed mission in the Apollo space program and the third meant to land on the Moon. The craft was launched from Kennedy Space Center on April 11, 1970, but the lunar landing was aborted after an oxygen tank in the service module failed two days into the mission. The crew instead looped around the Moon, and returned safely to Earth on April 17. The mission was commanded by Jim Lovell with Jack Swigert as command module pilot and Fred Haise as lunar module pilot. Swigert was a late replacement for Ken Mattingly, who was grounded after exposure to rubella.
  A routine stir of an oxygen tank ignited damaged wire insulation inside it, causing an explosion that vented the contents of both of the SM's oxygen tanks to space. Without oxygen, needed for breathing and for generating electric power, the SM's propulsion and life support systems could not operate. The CM's systems had to be shut down to conserve its remaining resources for reentry, forcing the crew to transfer to the LM as a lifeboat. With the lunar landing canceled, mission controllers worked to bring the crew home alive.
context_section_description: On February 5, 1971, Apollo 14's LM, Antares, landed on the Moon with astronauts Alan Shepard and Edgar Mitchell aboard, near Fra Mauro, the site Apollo 13 had been intended to explore. Haise served as CAPCOM during the descent to the Moon, and during the second EVA, during which Shepard and Mitchell explored near Cone crater.
  None of the Apollo 13 astronauts flew in space again. Lovell retired from NASA and the Navy in 1973, entering the private sector.  Swigert was to have flown on the 1975 Apollo-Soyuz Test Project (the first joint mission with the Soviet Union) but was removed as part of the fallout from the Apollo 15 postal covers incident. He took a leave of absence from NASA in 1973 and left the agency to enter politics, being elected to the House of Representatives in 1982, but died of cancer before he could be sworn in. Haise was slated to have been the commander of the canceled Apollo 19 mission, and flew the Space Shuttle Approach and Landing Tests before retiring from NASA in 1979.
  Several experiments were completed even though the mission did not land on the Moon. One involved the launch vehicle's  S-IVB (the Saturn V's third stage) which on prior missions had been sent into solar orbit once detached. The seismometer left by Apollo 12 had detected frequent impacts of small objects onto the Moon, but larger impacts would yield more information about the Moon's crust, so it was decided that beginning with Apollo 13, the S-IVB would be crashed into the Moon. The impact occurred at 77:56:40 into the mission and produced enough energy that the gain on the seismometer, 117 kilometers (73 mi) from the impact, had to be reduced. An experiment to measure the amount of atmospheric electrical phenomena during the ascent to orbit – added after Apollo 12 was struck by lightning – returned data indicating a heightened risk during marginal weather. A series of photographs of Earth, taken to test whether cloud height could be determined from synchronous satellites, achieved the desired results.
  As a joke, Grumman issued an invoice to North American Rockwell, prime contractor for the CSM, for "towing" the CSM most of the way to the Moon and back. Line items included 400001 miles at $1 each (plus $4 for the first mile); $536.05 for battery charging; oxygen; and four nights at $8 per night for an "additional guest in room" (Swigert). After a 20% "commercial discount", and a 2% discount for timely payment, the final total was $312,421.24. North American declined payment, noting that it had ferried three previous Grumman LMs to the Moon without compensation.
  The CM was disassembled for testing and parts remained in storage for years; some were used for a trainer for the Skylab Rescue Mission. That trainer was subsequently displayed at the Kentucky Science Center. Max Ary of the Cosmosphere made it a project to restore Odyssey; it is on display there, in Hutchinson, Kansas.
  Apollo 13 was called a "successful failure" by Lovell. Mike Massimino, a Space Shuttle astronaut, stated that Apollo 13 "showed teamwork, camaraderie and what NASA was really made of". The response to the accident has been repeatedly called, "NASA's finest hour"; it is still viewed that way. Author Colin Burgess wrote, "the life-or-death flight of Apollo 13 dramatically evinced the colossal risks inherent in manned spaceflight. Then, with the crew safely back on Earth, public apathy set in once again."
  William R. Compton, in his book about the Apollo Program, said of Apollo 13, "Only a heroic effort of real-time improvisation by mission operations teams saved the crew." Rick Houston and Milt Heflin, in their history of Mission Control, stated, "Apollo 13 proved mission control could bring those space voyagers back home again when their lives were on the line." Former NASA chief historian Roger D. Launius wrote, "More than any other incident in the history of spaceflight, recovery from this accident solidified the world's belief in NASA's capabilities". Nevertheless, the accident convinced some officials, such as Manned Spaceflight Center director Gilruth, that
