Successfully deployed from the space shuttle Challenger during the February 1984 STS-41B mission, the Westar 6 and Palapa B2 communications satellites ended up in incorrect orbits due to failures of their upper stage rockets. During STS-51A in November 1984, Discovery’s second trip into space, the crew of Commander Frederick H. “Rick” Hauck, Pilot David M. Walker, and Mission Specialists Joseph P. Allen, Anna L. Fisher, and Dale A. Gardner worked as a team to not only deploy two new satellites but also to retrieve the two wayward but otherwise healthy satellites for return to Earth. Hauck and Walker piloted Discovery to rendezvous with each satellite in turn, Allen and Gardner retrieved them during two spacewalks, and Fisher grappled and placed them in the payload bay for return to Earth. After refurbishment, both satellites returned to space.

NASA originally designated Hauck, Walker, Allen, Fisher, and Gardner as a crew in November 1983 and assigned them to STS-41H, a mission aboard Challenger planned for late September 1984 to either deploy the second Tracking and Data Relay Satellite (TDRS) or fly a classified payload for the Department of Defense. Due to ongoing problems with the Inertial Upper Stage that failed to put the first TDRS satellite in its correct orbit during STS-6, NASA canceled STS-41H and shifted Hauck’s crew to STS-51A. In February 1984, an agreement between NASA and the Canadian government added an as-yet unnamed Canadian payload specialist to the STS-51A crew. Managers later named the Canadian as Marc Garneau and reassigned him to STS-41G.

A shuffling of payloads following the STS-41D launch abort resulted in STS-51A now deploying the Anik D2 satellite for Canada and Leasat 1 (also known as Syncom IV-1) for the U.S. Navy. By early August, the launch date had slipped to Nov. 2, with NASA considering the possibility of retrieving the two wayward satellites from STS-41B, officially adding that task on Aug. 13. NASA selected Allen in 1967 as one of 11 scientist-astronauts, while the rest of the crew hail from the Class of 1978. Hauck, on his second mission after serving as pilot on STS-7, has the distinction as the first from his class to command a shuttle mission. Allen and Gardner had each flown one previous mission, STS-5 and STS-8, respectively, while for Walker and Fisher STS-51A represented their first flight. Fisher has the distinction as the first mother in space.

Discovery arrived back at NASA’s Kennedy Space Center (KSC) in Florida on Sept. 10, returning from Edwards Air Force Base in California following the STS-41D mission. Workers towed it to the Orbiter Processing Facility (OPF) the next day to begin the process of refurbishing it for STS-51A. On Oct. 18, they rolled it over to the Vehicle Assembly Building (VAB), for stacking with an External Tank and twin Solid Rocket Boosters.

The completed stack rolled out to Launch Pad 39A on Oct. 23. Two days later, the five-member STS-51A crew participated in the Terminal Countdown Demonstration Test, essentially a dress rehearsal for the actual countdown to launch. The crew returned to KSC on Nov. 5, the day the countdown began for a planned Nov. 7 launch. High upper-level winds that day forced a one-day delay.

Following deployment from Challenger during STS-41B, the upper stages of both the Westar 6 and Palapa B2 satellites malfunctioned, leaving them in non-useable 160-by-600-mile-high orbits instead of the intended 22,300-mile-high geostationary orbits required for their normal operations. While both satellites remained healthy, their own thrusters could not boost them to the proper orbits. NASA devised a plan to have astronauts retrieve the satellites during spacewalks using the jetpack known as the Manned Maneuvering Unit (MMU), after which the shuttle’s Canadian-built Remote Manipulator System (RMS) or robot arm would grapple them and place them into the cargo bay for return to Earth. Astronauts had demonstrated the capability of the MMU during the STS-41C Solar Max satellite repair mission in April 1984 and NASA felt confident of its ability to capture and return Westar and Palapa. 

In the weeks prior to STS-51A, ground controllers lowered the orbits of both satellites and reduced their spin rates from 50 to 1 rpm to enable capture by the shuttle astronauts. Engineers at NASA’s Johnson Space Center in Houston developed the Apogee Kick Motor Capture Device (ACD), otherwise known as the stinger due to its appearance, to allow an astronaut to capture the satellites while flying the MMU. Once relocated over the payload bay, a second astronaut would remove the satellite’s omnidirectional antenna with pruning shears and install an Antenna Bridge Structure (ABS) with a grapple fixture over the satellite’s main antenna dish. Allen would fly the MMU to capture Palapa, then he would switch roles with Gardner who would capture Westar. Fisher would use the RMS to grapple the satellites by this second fixture and lower them into specially built cradles to secure them into the payload bay.

Space shuttle Discovery roared off KSC’s Launch Pad 39A on Nov. 8, 1984, to begin the STS-51A mission and mark the orbiter’s first return to space. For Gardner, launch day coincided with his 36th birthday. The launch took place just 26 days after the landing of the previous mission, STS-41G, a then record-breaking turnaround time between shuttle flights. Eight and a half minutes after liftoff, Discovery and its five-member crew reached space and shortly thereafter settled into a 182-by-172-mile-high initial orbit. As their first order of business, the crew checked out the RMS to ensure its functionality for the satellite captures later in the mission. They also performed the first rendezvous burn to begin the approach to the Palapa satellite. The crew then settled down for its first night’s sleep in orbit.

The primary activity of the second flight day involved Allen deploying the 2,727-pound Anik D2 satellite via a spring ejection mechanism, occurring on time and with no issues. The crew also circularized the shuttle’s orbit at 186 miles. The next day, Gardner deployed the 17,000-pound Leasat 1 using the Frisbee style mechanism used to deploy the first Leasat during STS-41D two months earlier. With the satellite deployments complete, the crew began to focus on the rendezvous maneuvers to bring them close to the Palapa B2 satellite while Allen and Gardner verified the functionality of their spacesuits. On flight day 4, the astronauts reduced the pressure inside the shuttle from 14.7 pounds per square inch (psi) to 10.2 psi in order to prevent the spacewalking astronauts from developing the bends inside the spacesuits that operated at 4.3 psi.

On the fifth mission day, after Hauck and Walker piloted Discovery to within 35 feet of Palapa, Allen and Gardner exited the airlock to begin the spacewalk portion of the satellite capture. Allen donned the MMU mounted on the side wall of the cargo bay, attached the stinger to its arms, and flew out to Palapa. Once there, he inserted the stinger into the satellite’s Apogee Kick Motor bell and using the MMU’s attitude control system stopped Palapa’s spin.

Fisher then steered the RMS to capture a grapple fixture mounted on the stinger between Allen and the satellite. She then maneuvered them over the payload bay where Gardner waited to remove its omnidirectional antenna and install the bridge structure. However, Gardner could not attach the ABS to the satellite due to an unexpected clearance issue on the satellite. Using a backup plan, Allen undocked from the stinger, leaving it attached to the satellite as well as the RMS, and stowed the MMU in the payload bay. With Allen now holding the satellite by its antenna, Gardner attached an adaptor to the bottom end of the satellite to secure it in its cradle in the payload bay. This plan worked and Allen and Gardner completed the spacewalk in exactly six hours.

Between the two spacewalk days, the crew serviced the spacesuits, conducted routine maintenance on the shuttle, and prepared for the second rendezvous, this time to retrieve Westar. Allen and Gardner switched roles for the second spacewalk on flight day seven, with Gardner flying the MMU to capture Westar. The astronauts repeated the procedure from the first spacewalk, except for not removing the omni antenna so they could use it as a handhold. With Westar secured in the payload bay, Gardner and Allen completed the second spacewalk in 5 hours and 42 minutes.

During their final full day in space, Discovery’s crew repressurized the shuttle’s cabin to 14.7 psi and tidied the cabin in preparation for reentry. On Nov. 16, the astronauts closed the payload bay doors and fired the Orbital Maneuvering System engines to begin the descent back to Earth. Hauck guided Discovery to a smooth landing at KSC, completing a flight of 7 days, 23 hours, and 45 minutes. The crew had traveled nearly 3.3 million miles and completed 127 orbits around the Earth. The next day, workers towed Discovery to the OPF to begin preparing it for its next flight, STS-51C in January 1985.

As a postscript, STS-51A marked the last flight to use the MMUs, and the last untethered spacewalks until 1994 when STS-64 astronauts tested the Simplified Aid for EVA Rescue (SAFER). All subsequent spacewalks on the space shuttle and the International Space Station used safety tethers, with the SAFER as a backup in case a crew member disconnects from the vehicle.

On Dec. 7, 1984, in a ceremony at the White House, President Ronald W. Reagan presented the STS-51A crew with the Lloyd’s of London – the company had insured the two satellites they returned to Earth – Silver Medal for Meritorious Salvage Operations. Fisher has the distinction as only the second woman to receive that award. In February 1985, Lloyd’s flew the crew to London on the Concorde for a week of activities, including addressing the Lloyd’s underwriters and tea with Prince Charles at Kensington Palace.

Hong Kong-based AsiaSat purchased the Westar 6 satellite, refurbished it, and relaunched it as AsiaSat 1 on April 7, 1990, on a Chinese CZ-3 rocket. Title to the Palapa B2 satellite returned to Indonesia after its relaunch as Palapa B2R on April 13, 1990, aboard a Delta rocket.

      Before Apollo astronauts set foot upon the Moon, much remained unknown about the lunar surface. While most scientists believed the Moon had a solid surface that would support astronauts and their landing craft, a few believed a deep layer of dust covered it that would swallow any visitors. Until 1964, no closeup photographs of the lunar surface existed, only those obtained by Earth-based telescopes. 
      NASA’s Jet Propulsion Laboratory in Pasadena, California, managed the Ranger program, a series of spacecraft designed to return closeup images before impacting on the Moon’s surface. Ranger 7 first accomplished that goal in July 1964. On Feb. 17, 1965, its successor Ranger 8 launched toward the Moon, and three days later returned images of the Moon. The mission’s success helped the country meet President John F. Kennedy’s goal of a human Moon landing before the end of the decade. 

      Schematic diagram of the Ranger 8 spacecraft, showing its major components. NASA/JPL The television system aboard Ranger 8 showing its six cameras.NASA/JPL. Launch of Ranger 8. NASA. Ranger 8 lifted off from Cape Kennedy, now Cape Canaveral, Florida, on Feb. 17, 1965. The Atlas-Agena rocket first placed the spacecraft into Earth orbit before sending it on a lunar trajectory. The next day, the spacecraft carried out a mid-course correction, and on Feb. 20, Ranger 8 reached the Moon. The spacecraft’s six cameras turned on as planned, about eight minutes earlier than its predecessor to obtain images comparable in resolution to ground-based photographs for calibration purposes. Ranger 8 took its first photograph at an altitude of 1,560 miles, and during its final 23 minutes of flight, the spacecraft sent back 7,137 images of the lunar surface. The last image, taken at an altitude of 1,600 feet and 0.28 seconds before Ranger 8 impacted at 1.67 miles per second, had a resolution of about five feet. The spacecraft impacted 16 miles from its intended target in the Sea of Tranquility, ending a flight of 248,900 miles. Scientists had an interest in this area of the Moon as a possible landing zone for a future human landing, and indeed Apollo 11 landed 44 miles southeast of the Ranger 8 impact site in July 1969.

Ranger 8’s final images, taken at an altitude as low as 1,600 feet. NASA/JPL. One more Ranger mission followed, Ranger 9, in March 1965. Television networks broadcast Ranger 9’s images of the Alphonsus crater and the surrounding area “live” as the spacecraft approached its impact site in the crater – letting millions of Americans see the Moon up-close as it happened. Based on the photographs returned by the last three Rangers, scientists felt confident to move on to the next phase of robotic lunar exploration, the Surveyor series of soft landers. The Ranger photographs provided confidence that the lunar surface could support a soft-landing and that the Sea of Tranquility presented a good site for the first human landing. A little more than four years after the final Ranger images, Apollo 11 landed the first humans on the Moon.

The impacts of the Ranger probes left visible craters on the lunar surface, later photographed by orbiting spacecraft. Lunar Orbiter 2 and Apollo 16 both imaged the Ranger 8 impact site at relatively low resolution in 1966 and 1972, respectively. The Lunar Reconnaissance Orbiter imaged the crash site in greater detail in 2012.

      With two months to go before flight, the Apollo 13 prime crew of James Lovell, Thomas Mattingly, Fred Haise, and backups John Young, John Swigert, and Charles Duke continued to train for the 10-day mission planned to land in the Fra Mauro highlands region of the Moon. Engineers continued to prepare the Saturn V rocket and spacecraft at the launch pad for the April 11, 1970, liftoff and completed the Flight Readiness Test of the vehicle. All six astronauts spent many hours in flight simulators training while the Moon walkers practiced landing the Lunar Module and rehearsed their planned Moon walks. The crew for the next Moon landing mission, Apollo 14, participated in a geology field trip as part of their training for the flight then planned for October 1970. Meanwhile, NASA released Apollo 12 lunar samples to scientists and the Apollo 12 crew set off on a Presidential world goodwill tour.  
      At NASA’s Kennedy Space Center in Florida, engineers completed the Flight Readiness Test of the Apollo 13 Saturn V on Feb. 26. The test ensured that all systems are flight ready and compatible with ground support equipment, and the astronauts simulated portions of the countdown and powered flight. Successful completion of the readiness test cleared the way for a countdown dress rehearsal at the end of March.

NASA One of the greatest challenges astronauts faced during a lunar mission entailed completing a safe landing on the lunar surface. In addition to time spent in simulators, Apollo mission commanders and their backups trained for the final few hundred feet of the descent using the Lunar Landing Training Vehicle at Ellington Air Force Base near the Manned Spacecraft Center, now NASA’s Johnson Space Center, in Houston. Bell Aerosystems of Buffalo, New York, built the trainer for NASA to simulate the flying characteristics of the Lunar Module. Lovell and Young completed several flights in February 1970. Due to scheduling constraints with the trainer, lunar module pilots trained for their role in the landing using the Lunar Landing Research Facility at NASA’s Langley Research Center in Hampton, Virginia. Haise and Duke completed training sessions at the Langley facility in February.

On the ground, they rehearsed the moonwalks, setting up the American flag and the large S-band communications antenna, and collecting lunar samples. Engineers improved their spacesuits to make the expected longer spacewalks more comfortable for the crew members by installing eight-ounce bags of water inside the helmets for hydration.

The four experiments included the: 
      Charged Particle Lunar Environment Experiment designed to measure the flexes of charged particles  Cold Cathode Gauge Experiment designed to measure the pressure of the lunar atmosphere  Heat Flow Experiment designed to make thermal measurements of the lunar subsurface  Passive Seismic Experiment designed to measure any moonquakes, either naturally occurring or caused by artificial means   As an additional investigation, the astronauts planned to deploy and retrieve the Solar Wind Composition experiment, a sheet of aluminum foil to collect particles from the solar wind for analysis by scientists back on Earth after about 20 hours of exposure on the lunar surface.

They first traveled to Latin America, making stops in Venezuela, Peru, Chile, and Panama before continuing on to Europe, Africa, and Asia. 
      The groundbreaking science and discoveries made during Apollo missions has pushed NASA to explore the Moon more than ever before through the Artemis program. Apollo astronauts set up mirror arrays, or “retroreflectors,” on the Moon to accurately reflect laser light beamed at them from Earth with minimal scattering or diffusion. Retroreflectors are mirrors that reflect the incoming light back in the same incoming direction. Calculating the time required for the beams to bounce back allowed scientists to precisely measure the Moon’s shape and distance from Earth, both of which are directly affected by Earth’s gravitational pull. More than 50 years later, on the cusp of NASA’s crewed Artemis missions to the Moon, lunar research still leverages data from those Apollo-era retroreflectors.

      Official portrait of NASA Associate Administrator Jim Free, taken on Nov. 22, 2024, at the agency’s headquarters in Washington.Credit: NASA/Bill Ingalls NASA Associate Administrator Jim Free announced Wednesday his retirement, effective Saturday, Feb. 22. As associate administrator, Free has been the senior advisor to NASA Acting Administrator Janet Petro and leads NASA’s 10 center directors, as well as the mission directorate associate administrators at NASA Headquarters in Washington. He is the agency’s chief operating officer for more than 18,000 employees and oversaw an annual budget of more than $25 billion.  
      During his tenure as associate administrator since January 2024, NASA added nearly two dozen new signatories of the Artemis Accords, enabled the first Moon landing through the agency’s CLPS (Commercial Lunar Payload Services) initiative to deliver NASA science to the lunar surface, launched the Europa Clipper mission to study Jupiter’s icy ocean moon, and found molecules containing the ingredients for life in samples from asteroid Bennu delivered to Earth by NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification and Security–Regolith Explorer) spacecraft.
      “Throughout his career, Jim has been the ultimate servant leader – always putting the mission and the people of NASA first,” said Petro. “A remarkable engineer and a decisive leader, he combines deep technical expertise with an unwavering commitment to this agency’s mission. Jim’s legacy is one of selfless service, steadfast leadership, and a belief in the power of people.”
      Among the notable contributions to the nation during his NASA career, Free also championed a new path forward to return samples from Mars ahead of human missions to the Red Planet, supported the crews living and working aboard the International Space Station as they conduct hundreds of experiments and technology demonstrations, and engaged industry in new ways to secure a public/private partnership for NASA’s VIPER (Volatiles Investigating Polar Exploration Rover) mission on the Moon. 
      “It has been an honor to serve NASA and walk alongside the workforce that tackles the most difficult engineering challenges, pursues new scientific knowledge in our universe and beyond, develops technologies for future exploration endeavors, all while prioritizing safety every day for people on the ground, in the air, and in space,” Free said. “I am grateful for the opportunity to be part of the NASA family and contribute to the agency’s mission for the benefit of humanity.”
      During his more than three decades of service, Free has held several leadership roles at the agency. Before being named NASA associate administrator, Free served as associate administrator of the Exploration Systems Development Mission Directorate, where he oversaw the successful Artemis I mission and the development of NASA’s Moon to Mars architecture, defining and managing the systems development for the agency’s Artemis missions and planning for NASA’s integrated deep space exploration approach. 
      Free began his NASA career in 1990 as an engineer, working on Tracking and Data Relay Satellites at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. He later transferred to the agency’s Glenn Research Center in Cleveland and served in a variety of roles supporting the International Space Station and the development of the Orion spacecraft before transferring to NASA’s Johnson Space Center in Houston in 2008. Free returned to NASA Glenn in 2009 and was promoted to chief of the Space Flight Systems Directorate, where he oversaw the center’s space work. Free was named deputy center director in November 2010 and then served as center director from January 2013 until March 2016, when he was appointed to the NASA Headquarters position of deputy associate administrator for Technical [sic] in the Human Exploration and Operations Mission Directorate.
      A native of Northeast Ohio, Free earned his bachelor’s degree in aeronautics from Miami University in Oxford, Ohio, and his master’s degree in space systems engineering from Delft University of Technology in the Netherlands. 
      Free is the recipient of the Presidential Rank Award, NASA Distinguished Service Medal, NASA Outstanding Leadership Medal, NASA Exceptional Service Medal, NASA Significant Achievement Medal, and numerous other awards.

      On Feb. 11, 2000, space shuttle Endeavour took to the skies on its 14th trip into space on the Shuttle Radar Topography Mission (SRTM). The international STS-99 crew included Commander Kevin Kregel, Pilot Dominic Gorie, and Mission Specialists Gerhard Thiele of Germany representing the European Space Agency, Janet Kavandi, Janice Voss, who served as payload commander on the mission, and Mamoru Mohri of the National Space Development Agency (NASDA) of Japan, now the Japan Aerospace Exploration Agency.  
      During their 11-day mission, the astronauts used the radar instruments in Endeavour’s payload bay to obtain elevation data on a near global scale. The data produced the most complete, high-resolution digital elevation model of the Earth. The SRTM comprised a cooperative effort among NASA with the Jet Propulsion Laboratory (JPL) in Pasadena, California, managing the project, the Department of Defense’s National Imagery and Mapping Agency, the German space agency, and the Italian space agency. Prior to SRTM, scientists had a more detailed topographic map of Venus than of the Earth, thanks to the Magellan radar mapping mission.

NASA assigned the STS-99 crew in October 1998. For Kregel, selected by NASA as an astronaut in 1992, STS-99 marked his fourth trip to space, having served as pilot on STS-70 and STS-78 and commanded STS-87. Gorie and Kavandi, both selected in 1994, previously flew together as pilot and mission specialist, respectively, on STS-91, the final Shuttle Mir docking mission. Voss, selected in 1990, served as a mission specialist on STS-57 and STS-63, and as payload commander on STS-83 and STS-94. NASDA selected Mohri as an astronaut in 1985 and he previously flew as a payload specialist on STS-47, the Spacelab-J mission. Selected as an astronaut by the German space agency in 1987, Thiele joined the European Astronaut Corps in 1998, completing his first spaceflight on STS-99.  
      The SRTM used an innovative technique called radar interferometry to image the Earth’s landmasses at resolutions up to 30 times greater than previously achieved. Two of the synthetic aperture radar instruments comprising the SRTM payload had flown previously, on the STS-59 Shuttle Radar Laboratory-1 (SRL-1) and the STS-68 SRL-2 missions in April and October 1994, respectively.  A second receiver antenna, placed at the end of a 200-foot deployable mast, enabled the interferometry during SRTM.

The STS-99 crew walks out of crew quarters for the van ride to the launch pad. Workers rolled Endeavour to the Vehicle Assembly Building on Dec. 2 for mating with its external tank and solid rocket boosters, and then out to Launch Pad 39A on Dec. 13. The astronauts traveled to Kennedy to participate in the Terminal Countdown Demonstration Test Jan. 11-14, returning afterwards to Houston for final training. They traveled back to Kennedy on Jan. 27 for the first launch attempt four days later. After two launch attempts, the STS-99 mission prepared to liftoff on Feb. 11, 2000.

Astronauts Kevin Kregel, left, and Gerhard Thiele on Endeavour’s flight deck. Shortly after reaching orbit, the crew opened the payload bay doors and deployed the shuttle’s radiators.   Kavandi and Thiele turned on the instruments, deployed the 200-foot mast, and conducted initial checkouts of the radars. The crew split into two shifts to enable data collection around the clock during the mission. After overseeing the initial activation of the radars, the red shift of Kregel, Kavandi, and Thiele began their first sleep period as the blue shift of Gorie, Voss, and Mohri picked up with activation and began the first data takes. 
      The major crew activity for SRTM involved changing tapes every 30 minutes. The SRTM generated 332 high density tapes during more than 222 hours of data collection and these recordings covered 99.96 percent of the planned observations. Data collection finished on the mission’s 10th flight day, after which the astronauts reeled the mast back into its container in the payload bay.

NASA’s EarthKAM program enabled middle school students to remotely take photographs of the Earth using an electronic still camera mounted in one of the shuttle’s windows. The University of California at San Diego houses the control center for EarthKAM, linked with middle schools via the Internet. Students choose Earth targets of interest, and the camera takes photos of that region as the shuttle passes overhead. A then-record 75 schools from around the world participated in the EarthKAM project on STS-99, the camera returning 2,715 images of the Earth. 
      The STS-99 astronauts also spent time taking photographs of the Earth using handheld cameras and the high inclination orbit enabled views of some parts of the Earth rarely seen by shuttle astronauts.

      On Feb. 8, 2010, space shuttle Endeavour began its 24th trip into space, on the 20A assembly mission to the International Space Station, the 32nd shuttle flight to the orbiting lab. The STS-130 crew included Commander George Zamka, Pilot Terry Virts, and Mission Specialists Kathryn Hire, Stephen Robinson, Nicholas Patrick, and Robert Behnken. During the nearly 14-day mission, they worked jointly with the five-person Expedition 22 crew during nearly 10 days of docked operations. The mission’s primary objectives included delivering the Tranquility module and the cupola to the space station, adding 21 tons of hardware to the facility. Behnken and Patrick conducted three spacewalks to aid in the installation of Tranquility.

Liftoff of space shuttle Endeavour on STS-130. Endeavour rolled out to Launch Pad 39A on Jan. 6, 2010, targeting a Feb. 7 launch. The crew arrived at NASA’s Kennedy Space Center in Florida on Feb. 3 to prepare for launch. Inclement weather delayed the initial launch attempt by 24 hours. On Feb. 8, at 4:14 a.m. EST, space shuttle Endeavour lifted off, carrying its six-person crew. The flight marked Robinson’s fourth trip into space, previously serving as a mission specialist on STS-85, STS-95, and STS-114, Zamka’s, Hire’s, Patrick’s, and Behnken’s second time in space, having flown on STS-120, STS-90, STS-116, and STS-123, respectively, while Virts enjoyed his first taste of weightlessness.

After reaching orbit, the astronauts opened the payload bay doors, deployed the shuttle’s radiators, and removed their bulky launch and entry suits, stowing them for the remainder of the flight. They spent six hours on their second day in space conducting a detailed inspection of Endeavour’s nose cap and wing leading edges, taking turns operating the shuttle remote manipulator system, or robotic arm, and the Orbiter Boom Sensor System.  
      On the mission’s third day, Zamka assisted by his crewmates brought Endeavour in for a docking with the space station. During the rendezvous, Zamka stopped the approach at 600 feet and completed a pitch maneuver so astronauts aboard the station could photograph Endeavour’s underside to look for any damage to the tiles. Zamka then manually guided Endeavour to a docking at the Pressurized Mating Adapter-2 attached to the Harmony module. After docking, the crews opened the hatches and the five-person station crew welcomed the six-member shuttle crew. Patrick and Expedition 22 Flight Engineer Timothy “T.J.” Creamer used the space station robotic arm to remove the inspection boom and hand it off to the shuttle arm operated by Hire and Virts. At the end of the day, Behnken and Partick entered the station’s airlock, reduced its pressure and breathed pure oxygen for an hour before and an hour after sleep to rid their bodies of nitrogen to prevent the bends.

Nicholas Patrick, left, and Robert Behnken during the mission’s second spacewalk. The astronauts completed the major transfer activity of the mission on flight day five, a highly choreographed spacewalk and robotics effort to move the Tranquility and cupola modules from the shuttle to the station. Behnken and Patrick exited the airlock to begin the mission’s first excursion, first venturing to the shuttle payload bay to remove launch locks from Tranquility. Virts and Hire used the station arm to remove the joined modules from the payload bay and attach it to the Unity module’s port side. Behnken and Partick connected temporary heater and data cables to the new module. This first spacewalk lasted six hours 32 minutes. The next day, the joint crews began outfitting Tranquility and preparing to relocate the cupola from the end of the module to its Earth-facing port. 
      On the mission’s seventh day, some of the astronauts continued outfitting and configuring the new modules. In the meantime, Behnken and Patrick stepped outside for a five-hour 54-minute excursion, to install ammonia coolant loops and thermal blankets to protect the ammonia hoses, and outfitted Tranquility’s Earth-facing port to accept the cupola.

The next day, Hire and Virts, assisted by Expedition 22 Commander Jeffery Williams, used the station’s robotic arm to relocate the cupola. On flight day 9, Behnken and Patrick operated the station arm to relocate the Pressurized Mating Adapter-3 from Harmony to Tranquility. The crews continued internal cargo transfers and began outfitting the cupola.  
      On the mission’s 10th day, Patrick and Behnken completed their third and final spacewalk. During the five-hour 48-minute excursion, they removed thermal blankets and launch locks from the cupola, installed handrails, connected the second cooling loop on Tranquility, and connected heater and data cables. Inside the cupola, Hire and Virts installed the robotics workstation. Across their three spacewalks, Behnken and Patrick spent 18 hours 14 minutes outside.

The crews spent flight day 11 outfitting Tranquility with systems racks and other equipment moved from the Destiny U.S. Laboratory module. Virts finished installing robotic workstation equipment in the Cupola. Behnken and Partick transferred their spacesuits back to the shuttle for return to Earth. The crew received a phone call from President Barack Obama and several schoolchildren. Zamka and Virts used the shuttle’s thrusters to reboost the space station.  
      The next day, after holding a news conference with reporters on the ground, shuttle commander Zamka and station commander Williams held a ribbon-cutting ceremony to formally declare Tranquility and the cupola open for business. After a final meal together, the two crews held a farewell ceremony, returned to their respective spacecraft, and closed the hatches.

On flight day 13, with Virts at the controls, Endeavour undocked from the space station, having spent nearly 10 days as a single spacecraft. The astronauts used the shuttle’s arm and boom sensors to perform a late inspection of Endeavour’s thermal protection system. On flight day 14, Zamka and Virts tested the orbiter’s reaction control system thrusters and flight control surfaces in preparation for the next day’s entry and landing.  
      On Feb. 22, Hire and Robinson closed Endeavour’s payload bay doors. The six astronauts donned their launch and entry suits and strapped themselves into their seats. Zamka and Virts fired Endeavour’s two Orbital Maneuvering System engines to bring them out of orbit and Zamka guided Endeavour to a smooth touchdown at Kennedy’s Shuttle Landing Facility. The landing capped off a successful mission of 13 days, 18 hours, six minutes and 217 orbits of the Earth. Workers at Kennedy towed Endeavour to the processing facility to prepare it for its next and final flight, STS-134 in May 2011, and the astronauts returned to Houston for a welcoming ceremony at Ellington Field.
