Kennedy committed the nation to landing a man on the Moon and returning him safely to the Earth. While this goal presented an unprecedented engineering challenge, some scientists were more concerned whether the astronauts or the lunar samples could return potentially harmful microorganisms from the Moon, with possibly devastating effects to life on Earth. Although considered remote, at the time this possibility could not be ruled out and methods needed to be developed to protect the planet from any back-contamination by lunar microorganisms. The Lunar Receiving Laboratory (LRL), located in Building 37 at the Manned Spacecraft Center (MSC), now NASA\u2019s Johnson Space Center (JSC) in Houston, served as a critical component of this planetary protection plan during the Apollo program. <\/p>\n\n\n\n<p><img decoding=\"async\" loading=\"lazy\" alt=\"building_on_a_mission_lrl_2_lrl_schematic\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/10\/building_on_a_mission_lrl_2_lrl_schematic_s67-00696_cropped.jpg\" width=\"292\" height=\"220\"> <img decoding=\"async\" loading=\"lazy\" alt=\"building_on_a_mission_lrl_3_lrl_transport_scheme_color\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/10\/building_on_a_mission_lrl_3_lrl_transport_scheme_color_cropped_s67-00688.jpg\" width=\"326\" height=\"220\"><br>\n<em>Left: Schematic showing the major functional areas of the Lunar Receiving Laboratory (LRL).<br>\nRight: Diagram showing the role of the LRL in the overall postflight transportation<br>\nand quarantine operation.<\/em><\/p>\n\n\n\n<p>The facility was specially designed and built to isolate astronauts and rock samples returning from the Moon to prevent back-contamination of the Earth by any possible lunar microorganisms, and to prevent contamination of the lunar samples. To accomplish these goals, the LRL consisted of four major functional areas: the Crew Reception Area (CRA), the Sample Operations Area, the Radiation Counting Laboratory, and the Administrative and Support Area. The CRA and the Sample Operations Area were inside the biological barrier to prevent any accidental contamination of the Earth with any lunar microorganisms. A complex vacuum system ensured that air could not escape from the facility and that the terrestrial atmosphere would not contaminate the pristine lunar samples. The CRA included dormitories for the three returning astronauts and for the staff who supported them during their 21-day quarantine. A separate room within the CRA held the Apollo Command Module during the quarantine period. Medical facilities, a small gym, a kitchen and dining area, and a glass-walled room for holding debriefings and press conferences rounded out the CRA. The Sample Operations Area included a gas analysis laboratory, a vacuum laboratory, and physical and biological sciences test laboratories. In these laboratories, many including vacuum gloveboxes, scientists put the lunar samples through a variety of analyses to test their structure and composition and their effects on biological specimens. The Radiation Counting Lab housed a state-of-the-art gamma ray spectrometry laboratory constructed of low-background radiation material and built 50 feet underground to minimize exposure to background radiation. The Administration and Support Area housed offices and conference rooms.<\/p>\n\n\n\n<p><img decoding=\"async\" loading=\"lazy\" alt=\"building_on_a_mission_lrl_4_lrl_ground_prep_sep_22_1966\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/10\/building_on_a_mission_lrl_4_lrl_ground_prep_sep_22_1966_s66-54146.jpg\" width=\"306\" height=\"240\"> <img decoding=\"async\" loading=\"lazy\" alt=\"building_on_a_mission_lrl_5_lrl_early_construction_oct_13_1966\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/10\/building_on_a_mission_lrl_5_lrl_early_construction_oct_13_1966_s66-57130.jpg\" width=\"304\" height=\"240\"><br>\n<em>Left: Ground preparation for the Building 37 site in September 1966.<br>\nRight: Initial steel structure in place for Building 37 in October 1966.<\/em><\/p>\n\n\n\n<p><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/10\/building_on_a_mission_lrl_6_lrl_under_construction_dec_3_1966_s66-56323.jpg\" alt=\"building_on_a_mission_lrl_6_lrl_under_construction_dec_3_1966\" width=\"228\" height=\"180\"> <img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/10\/building_on_a_mission_lrl_7_lrl_under_construction_radiation_vault_oct_13_1966_s66-57127.jpg\" alt=\"building_on_a_mission_lrl_7_lrl_under_construction_radiation_vault_oct_13_1966\" width=\"229\" height=\"180\"> <img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/10\/building_on_a_mission_lrl_8_lrl_aerial_view_oct_1967_cropped_s67-46210.jpg\" alt=\"building_on_a_mission_lrl_8_lrl_aerial_view_oct_1967\" width=\"272\" height=\"180\"><br><em>Left: Aerial view of the Building 37 site in October 1966, with the circular 50-foot deep hole for the radiation vault.

A full-scale simulation, including of the Crew Reception Area, was completed in March and April 1969.
