Unfortunately, the mission to explore the Fra Mauro region of the Moon did not go as planned. What many viewed as a now \u201croutine\u201d mission soon had millions around the globe glued to television sets watching and hoping for a positive outcome for one of the most intense episodes in the history of space exploration.<\/p>\n\n\n\n<p>The overwhelming success of the Apollo 11 mission in July 1969 and the subsequent Apollo 12 mission gave many the impression that lunar landings were almost routine in nature. Combined with clashes over the Vietnam War, the public\u2019s attention increasingly turned away from the Apollo missions. Shrinking budgets threatened much of the remaining Apollo missions leading eventually to the cancellation of Apollo 18, 19, and 20. Those of the superstitious persuasion noted that even the upcoming Apollo launch suffered from all the unlucky lore surrounding the number 13. Some validity to those fears proved warranted when a measles scare prompted the replacement of command module pilot, Ken Mattingly with Jack Swigert.<\/p>\n\n\n<div id=\"\" class=\"hds-media hds-module wp-block-image\"><div class=\"margin-left-auto margin-right-auto nasa-block-align-inline\"><div class=\"hds-media-wrapper margin-left-auto margin-right-auto\"><figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-none \"><a href=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2020\/04\/s69-60662_orig.jpg\"><img fetchpriority=\"high\" decoding=\"async\" width=\"2048\" height=\"2048\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2020\/04\/s69-60662_orig.jpg?w=2048\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"Apollo 13 Emblem\" style=\"transform: scale(1); transform-origin: 50% 50%; object-position: 50% 50%; object-fit: cover;\" block_context=\"nasa-block\" srcset=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2020\/04\/s69-60662_orig.jpg 3969w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2020\/04\/s69-60662_orig.jpg?resize=150,150 150w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2020\/04\/s69-60662_orig.jpg?resize=300,300 300w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2020\/04\/s69-60662_orig.jpg?resize=768,768 768w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2020\/04\/s69-60662_orig.jpg?resize=1024,1024 1024w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2020\/04\/s69-60662_orig.jpg?resize=1536,1536 1536w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2020\/04\/s69-60662_orig.jpg?resize=2048,2048 2048w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2020\/04\/s69-60662_orig.jpg?resize=50,50 50w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2020\/04\/s69-60662_orig.jpg?resize=100,100 100w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2020\/04\/s69-60662_orig.jpg?resize=200,200 200w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2020\/04\/s69-60662_orig.jpg?resize=400,400 400w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2020\/04\/s69-60662_orig.jpg?resize=600,600 600w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2020\/04\/s69-60662_orig.jpg?resize=900,900 900w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2020\/04\/s69-60662_orig.jpg?resize=1200,1200 1200w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2020\/04\/s69-60662_orig.jpg?resize=2000,2000 2000w\" sizes=\"(max-width: 2048px) 100vw, 2048px\" loading=\"eager\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\"><div class=\"hds-caption-text p-sm margin-0\">The Apollo 13 mission was to be the third lunar landing in the program before an on board explosion forced the mission to circle the Moon without landing.

Looking to the outside of the command module Odyssey, Lovell noticed they were \u201cventing something out into the\u2026into space.\u201d That venting was in fact the lifeblood of the mission, oxygen. The crew discovered that the explosion in tank number two had also damaged tank number one\u2014a problem which made use of the fuel cells impossible threatening the eventual loss of all electrical power and water. With the lunar landing now erased from the equation, both the astronauts aboard Apollo 13 and NASA personnel on the ground worked tirelessly around the clock to develop solutions that would allow them to return home safely.<\/p>\n\n\n\n<p>The immediate response plan was to enter what was known as \u201clifeboat mode.\u201d Here, the lunar module, <em>Aquarius <\/em>became central to efforts to save the beleaguered space craft and crew. <em>Aquarius\u2019 <\/em>full oxygen tank and descent engine both proved critical in keeping the crew alive and returning them to Earth. Along with the extreme shortage of water and electrical power, the crew also encountered dangerous levels of carbon dioxide. Plenty of lithium hydroxide canisters, designed to remove the gas from the spacecraft, were on hand in the command module. The problem, however, was that those square cannisters were not compatible with the round openings in the <em>Aquarius. <\/em>Doing what engineers do, support staff in Houston devised a method for fitting a \u201csquare peg in a round hole.\u201d<\/p>\n\n\n<div id=\"\" class=\"hds-media hds-module wp-block-image\"><div class=\"margin-left-auto margin-right-auto nasa-block-align-inline\"><div class=\"hds-media-wrapper margin-left-auto margin-right-auto\"><figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-none \"><a href=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2020\/04\/s70-35606_orig.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"2048\" height=\"1356\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2020\/04\/s70-35606_orig.jpg?w=2048\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"Rear Admiral Donald C.

One final problem remained\u2014powering up the command module after its seemingly long hiatus from the action. Under normal conditions, the process of writing new procedures would take three months. Houston had three days. One major issue concerned whether cold condensation on the instrumentation would short circuit when power returned. Years later, Haise remembered the command module looking as though someone had \u201csprayed it with a hose\u201d and that the crew had to \u201cwipe everything off with a towel.\u201d Fortunately, activation caused no arching. Why not? The answer could be found in the lessons learned from the devastating Apollo 1 fire in January 1967 after which a major redesign was undertaken to add increased insulation for the better protection of the wiring.<\/p>\n\n\n\n<p>On April 17, the crew said goodbye to <em>Aquarius<\/em> and returned to Earth\u2014splashing down in the Pacific Ocean near Samoa. Only when the crew was safely aboard the recovery ship U.S.S. Iwo Jima could everyone at NASA and around the world finally begin to exhale. The lessons learned from the successful failure of Apollo 13 were rapidly applied to the remaining Apollo missions and continue to guide safety and mission assurance at NASA today.<\/p>\n\n\n<div
