It was the first mission focused almost entirely on studying the Earth through the use of a satellite, multiple instruments and cameras, as well as crew observations to accomplish these goals. The crew of STS-41G also set several firsts. The Commander, Robert L. Crippen, became the first astronaut to make a fourth flight aboard the Space Shuttle. He did so only 5\u00bd months after returning from his previous mission, STS-41C, becoming the first American to make two trips into space in one calendar year and the first to fly back-to-back missions on the same orbiter. The Pilot, Jon A. McBride, was making his first flight into space. The three Mission Specialists were Kathryn D. Sullivan, Sally K. Ride, and David C. Leestma. This marked the first time that two women flew in space at the same time, with Ride becoming the first American woman to fly a second mission and Sullivan the first American woman to conduct an Extravehicular Activity (EVA), or spacewalk. Leestma was the first of the astronaut class of 1980 to make a space flight. The two Payload Specialists, Marc Garneau, the first Canadian in space, and Paul D. Scully-Power, a civilian employee of the US Naval Research Laboratory and the first oceanographer and the first Australian-born American citizen to fly in space, rounded out the seven-member crew, the largest crew flown to that time.<\/p>\n\n\n\n<p><img loading=\"lazy\" decoding=\"async\" alt=\"sts_41g_patch\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2019\/10\/sts_41g_patch_s84-36158.jpg\" width=\"277\" height=\"301\"> <img loading=\"lazy\" decoding=\"async\" alt=\"sts_41g_crew_photo_s84-37981\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2019\/10\/sts_41g_crew_photo_s84-37981.jpg\" width=\"384\" height=\"302\"><br>\n<em>Left: STS-41G crew patch.

NASA\u2019s Office of Space and Terrestrial Applications sponsored a cargo bay-mounted payload (OSTA-3) consisting of four instruments. Managed by the Jet Propulsion Laboratory in Pasadena, California, the Shuttle Imaging Radar-B (SIR-B), an updated version of SIR-A flown on STS-2, used synthetic aperture radar to support investigations in diverse disciplines such as archaeology, geology, cartography, oceanography, and vegetation studies. Making its first flight into space, the 900-pound Large Format Camera (LFC) took images of selected Earth targets on 9-by-18-inch film with 70-foot resolution. The Measurement of Air Pollution from Satellites (MAPS) experiment provided information about industrial pollutants in the atmosphere. The Feature Identification and Location Experiment (FILE) contained two television cameras to improve the efficiency of future remote sensing equipment. In an orbit inclined 57 degrees to the Equator, the instruments aboard the Space Shuttle <em>Challenger<\/em> could observe more than 75% of the Earth\u2019s surface. <\/p>\n\n\n\n<p>The Orbital Refueling System (ORS), managed by the Johnson Space Center in Houston, was not directly an Earth observation payload, but it was designed to assess the feasibility of conducting an on-orbit refueling of the Landsat-4 remote sensing satellite, then planned to take place in 1987, as well as Department of Defense satellites that were not designed for on-orbit refueling. In the demonstration, the astronauts remotely controlled the transfer of hydrazine, a highly toxic fuel, between two tanks mounted in the payload bay. During a spacewalk, two crewmembers simulated connecting the refueling system to a satellite and later tested the connection with another remotely controlled fuel transfer. Rounding out the payload activities, the large format IMAX camera made its third trip into space, with footage used to produce the film <em>The Dream is Alive<\/em>.<\/p>\n\n\n\n<p><img loading=\"lazy\" decoding=\"async\" alt=\"sts_41g_launch\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2019\/10\/sts_41g_launch_41g-90090.jpg\" width=\"142\" height=\"252\"> <img loading=\"lazy\" decoding=\"async\" alt=\"sts_41g_launch\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2019\/10\/sts_41g_launch_41g-90139.jpg\" width=\"253\" height=\"251\"> <img loading=\"lazy\" decoding=\"async\" alt=\"sts_41g_erbs_deploy_41g-49-019.\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2019\/10\/sts_41g_erbs_deploy_41g-49-019.jpg\" width=\"259\" height=\"251\"><br>\n<em>Left and middle: Two views of the launch of <\/em>Challenger<em> on the STS-41G mission.<br>\nRight: ERBS just before the RMS released it.<\/em><\/p>\n\n\n\n<p>Space Shuttle <em>Challenger<\/em> roared off Launch Pad 39A 15 minutes before sunrise on Oct. 5, 1984, to begin the STS-41G mission. The launch took place just 30 days after the landing of the previous mission, STS-41D. That record-breaking turnaround time between Shuttle flights didn\u2019t last long, as it was broken just 26 days after <em>Challenger<\/em>\u2019s landing with the launch of <em>Discovery<\/em> on STS-51A. Eight and a half minutes after liftoff, <em>Challenger<\/em> and its seven-member crew were in space and shortly thereafter settled into a 218-mile high orbit, ideal for the deployment of the 5,087-pound ERBS. The crew noted that a 40-inch strip of Flexible Reusable Surface Insulation (FRSI) was missing from the right hand Orbiter Maneuvering System (OMS) pod, presumably lost during launch. Mission Control determined that this would not have any impact during reentry.<\/p>\n\n\n\n<p>Ride grappled the ERBS with the Shuttle\u2019s Canadian-built Remote Manipulator System (RMS) or robot arm but when she commanded the satellite to deploy its solar arrays, nothing happened. Mission Control surmised that the hinges on the arrays had frozen, and after Ride oriented the satellite into direct sunlight and shook it slightly on the end of the arm, the panels deployed. She released ERBS about two and a half hours late and McBride fired <em>Challenger<\/em>\u2019s steering jets to pull away from the satellite. Its onboard thrusters boosted ERBS into its operational 380-mile high orbit. With an expected two-year lifetime, it actually operated until October 14, 2005, returning data about how the Earth\u2019s atmosphere absorbs and re-radiates the Sun\u2019s energy, contributing significant information about global climate change.<\/p>\n\n\n\n<p><img loading=\"lazy\" decoding=\"async\" alt=\"sts_41g_sir-b_deploy\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2019\/10\/sts_41g_sir-b_deploy_41g-03-026.jpg\" width=\"335\" height=\"219\"> <img loading=\"lazy\" decoding=\"async\" alt=\"sts_41g_mcbride_w_imax_camera\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2019\/10\/sts_41g_mcbride_w_imax_camera_41g-16-029.jpg\" width=\"335\" height=\"219\"><br>\n<em>Left: The SIR-B panel being opened in <\/em>Challenger<em>\u2019s payload bay.<br>\nRight: McBride with the IMAX camera in the middeck.  <\/em><\/p>\n\n\n\n<p>Near the end of their first day in space, the astronauts opened the panels of the SIR-B antenna and activated it, also deploying the Ku-band antenna that <em>Challenger<\/em> used to communicate with the Tracking and Data Relay System (TDRS) satellite. The SIR-B required a working Ku-band antenna to downlink the large volume of data it collected, although it could store a limited amount on onboard tape recorders. But after about two minutes, the data stream to the ground stopped. One of the two motors that steered the Ku antenna failed and it could no longer point to the TDRS satellite. Mission Control devised a workaround to fix the Ku antenna in one position and steer the orbiter to point it to the TDRS satellite and downlink the stored data to the ground. <em>Challenger<\/em> carried sufficient fuel for all the maneuvering, but the extra time for the attitude changes resulted in achieving only about 40% of the planned data takes. Among the SIR-B discoveries was the 3,000-year old lost city of Udar in the desert of Oman.<\/p>\n\n\n\n<p><img loading=\"lazy\" decoding=\"async\" alt=\"sts_41g_garneau_patch\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2019\/10\/sts_41g_garneau_patch.jpg\" width=\"258\" height=\"263\"> <img loading=\"lazy\" decoding=\"async\" alt=\"sts_41g_spiral_eddies_eastern_med\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2019\/10\/sts_41g_spiral_eddies_eastern_med_17-35-094.jpg\" width=\"395\" height=\"262\"><br>\n<em>Left: Patch for Garneau\u2019s mission.

Flight rules required that the SIR-B antenna be stowed for such maneuvers but the latches to clamp the antenna closed failed to activate. Ride used the RMS to nudge the antenna panel closed. From the orbiter\u2019s flight deck, Leestma successfully completed the first ORS remote-controlled hydrazine fuel transfer. Garneau began working on his ten CANEX investigations related to medical, atmospheric, climatic, materials and robotic sciences while Scully-Power initiated his oceanographic observations. Despite greater than expected global cloud cover, he successfully photographed spiral eddies in the world\u2019s oceans, particularly notable in the eastern Mediterranean Sea.<\/p>\n\n\n\n<p><img loading=\"lazy\" decoding=\"async\" alt=\"sts_41g_two_women_in_space\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2019\/10\/sts_41g_two_women_in_space_41g-07-021.jpg\" width=\"331\" height=\"223\"> <img loading=\"lazy\" decoding=\"async\" alt=\"sts_41g_garneau_and_scully-power_in_middeck\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2019\/10\/sts_41g_garneau_and_scully-power_in_middeck_41g-14-0022.jpg\" width=\"333\" height=\"225\"><br>\n<em>Left: Sullivan (left) and Ride on <\/em>Challenger<em>\u2019s flight deck.

For the next few days, all the experiments continued recording their data, including Garneau\u2019s CANEX and Scully-Power\u2019s oceanography studies. Leestma completed several scheduled ORS fuel transfers prior to the spacewalk.  Preparations for that activity began on flight day 6 with the crew lowering the cabin pressure inside <em>Challenger<\/em> from the normal sea level 14.7 pounds per square inch (psi) to 10.2 psi. This was done to prevent the buildup of nitrogen bubbles in the bloodstreams of the two EVA crewmembers, Leestma and Sullivan, that could result in the development of the bends. The two verified the readiness of their spacesuits.<\/p>\n\n\n\n<p><img loading=\"lazy\" decoding=\"async\" alt=\"sts_41g_eva_lesstma_and_sullivan_s84-43433\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2019\/10\/sts_41g_eva_lesstma_and_sullivan_s84-43433.jpg\" width=\"261\" height=\"261\"> <img loading=\"lazy\" decoding=\"async\" alt=\"sts_41g_inflight_crew_photo\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2019\/10\/sts_41g_inflight_crew_photo_41g-19-006.jpg\" width=\"394\" height=\"261\"><br>\n<em>Left: Leestma (at left, with red stripes on his suit) and Sullivan during their EVA.<br>\nRight: Traditional inflight photo of the STS-41G crew (front, left to right) McBride, Ride, Sullivan, and<br>\nLeestma, (back, left to right) Scully-Power, Crippen, and Garneau.<\/em><\/p>\n\n\n\n<p>On flight day 7, Leestma and Sullivan, assisted by McBride, donned their spacesuits and began their EVA. After gathering their tools, the two translated down to the rear of the cargo bay where the ORS was positioned. With Sullivan documenting and assisting with the activity, Leestma installed the valve assembly into the simulated Landsat propulsion plumbing. Having completed the ORS objectives, Leestma and Sullivan proceeded back toward the airlock, stopping first at the Ku antenna where Sullivan secured it in place. They returned inside after an EVA that lasted 3 hours and 29 minutes. After the conclusion of the EVA, the crew brought <em>Challenger<\/em>\u2019s cabin pressure back up to 14.7 psi.<\/p>\n\n\n\n<p><img loading=\"lazy\" decoding=\"async\" alt=\"sts_41g_landing_41g\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2019\/10\/sts_41g_landing_41g-90235.jpg\" width=\"332\" height=\"216\"> <img loading=\"lazy\" decoding=\"async\" alt=\"sts_41g_crew_egress_post_landing\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2019\/10\/sts_41g_crew_egress_post_landing.jpg\" width=\"332\" height=\"216\"><br>\n<em>Left: Space Shuttle <\/em>Challenger<em> landing at KSC at the end of the STS-41G mission.<br>\nRight: The crew of STS-41G descends from <\/em>Challenger<em> after completing a highly successful mission.<\/em><\/p>\n\n\n\n<p>During their final full day in space, <em>Challenger<\/em>\u2019s crew tidied the cabin for reentry and completed the final SIR-B and other Earth observations.

Because of the mission\u2019s 57-degree inclination, the reentry path took <em>Challenger<\/em> and its crew over the eastern United States, another Shuttle first. Crippen guided the orbiter to a smooth landing at KSC, completing a flight of 8 days, 5 hours, and 24 minutes.
