The 11-day mission was the second flight of the Wake Shield Facility (WSF), a saucer-shaped satellite that was to fly free of the Shuttle for several days. The purpose of the WSF was to grow thin films in a near perfect vacuum created by the wake of the satellite as it moved through space. [1] The crew also deployed and retrieved the Spartan 201 astronomy satellite, performed a six-hour spacewalk to test assembly techniques for the international Space Station and tested thermal improvements made to spacesuits used during space walks.
The Spartan 201 free-flyer made its third flight aboard the Shuttle. The Spartan 201 mission was a scientific research effort aimed at the investigation of the interaction between the Sun and its outflowing wind of charged particles. Spartan's goal was to study the outer atmosphere of the Sun and its transition into the solar wind that constantly flows past the Earth. [5]
STS-69 saw the first flight of the International Extreme Ultraviolet Hitchhiker (IEH-1), the first of five planned flights to measure and monitor long-term variations in the magnitude of absolute extreme ultraviolet (EUV) flux coming from the Sun, and to study EUV emissions from the plasma torus system around Jupiter originating from its moon Io. [2]
Also aboard Endeavour were the combined Capillary Pumped Loop-2 [6] /Gas Bridge Assembly [7] (CAPL-2/GBA) payload. This experiment consisted of the CAPL-2 Hitchhiker payload designed as an in-orbit microgravity demonstration of a cooling system planned for the Earth Observing System Program and the Thermal Energy Storage-2 payload, part of an effort to develop advanced energy generation techniques. Also a part of this payload were several Getaway Special (GAS) experiments which investigated areas such as the interaction of spacecraft attitude and orbit control systems with spacecraft structures, fluid-filled beams as structural dampers in space and the effects of smoldering combustion in a long-term microgravity environment.
Another payload flown with a connection to the development of the Space Station was the Electrolysis Performance Improvement Concept Study (EPICS). Supply of oxygen and hydrogen by electrolyzing water in space plays an important role in meeting NASA's needs and goals for future space missions. On-board generation of oxygen was expected to reduce the annual resupply requirement for the Space Station by approximately 5,400 kilograms (11,900 lb).
Other payloads aboard were the National Institutes of Health- Cells-4 (NIH-C4) experiment that investigates bone loss during space flight; the Biological Research in Canister-6 (BRIC-6) that studies the gravity-sensing mechanism within mammalian cells. Also flying were two commercial experiments. (CMIX-4) whose objectives included analysis of cell change in microgravity along with studies of neuro-muscular development disorders and the Commercial Generic Bioprocessing Apparatus-7 (CGBA-7). CGBA was a secondary payload that served as an incubator and data collection point for experiments in pharmaceuticals testing and biomedicine, bioprocessing and biotechnology, agriculture and the environment. [8]
The Thermal Energy Storage (TES-2) experiment was also part of the CAPL-2/GBA-6. The TES-2 payload was designed to provide data for understanding the long-duration behavior of thermal energy storage fluoride salts that undergo repeated melting and freezing in microgravity. The TES-2 payload was designed to study the microgravity behavior of voids in lithium fluoride–calcium fluoride eutectic, a thermal energy storage salt. Data from this experiment would validate a computer code called TESSIM, [9] useful for the analysis of heat receivers in advanced solar dynamic power system designs.
STS-107 was the 113th flight of the Space Shuttle program, and the 28th and final flight of Space Shuttle Columbia. The mission ended on February 1, 2003, with the Space Shuttle Columbia disaster which killed all seven crew members and destroyed the space shuttle. It was the 88th post-Challenger disaster mission.
James Donald "Wxb" Wetherbee, is a retired United States Navy officer and aviator, test pilot, aerospace engineer, and NASA astronaut. He is a veteran of six Space Shuttle missions and is the only American to have commanded five spaceflight missions.
STS-93 in 1999 marked the 95th launch of the Space Shuttle, the 26th launch of Columbia, and the 21st night launch of a Space Shuttle. Eileen Collins became the first female shuttle Commander on this flight. Its primary mission was to launch the Chandra X-ray Observatory, the heaviest payload ever carried by the Space Shuttle system, at 22,780 kilograms (50,222 lb).
STS-51-B was the 17th flight of the NASA Space Shuttle program and the seventh flight of Space Shuttle Challenger. The launch of Challenger on April 29, 1985, was delayed by 2 minutes and 18 seconds, due to a launch processing failure. Challenger was initially rolled out to the pad to launch on the STS-51-E mission. The shuttle was rolled back when a timing issue emerged with the TDRS-B satellite. When STS-51-E was canceled, Challenger was remanifested with the STS-51-B payloads. The shuttle landed successfully on May 6, 1985, after a week-long mission.
STS-52 was a Space Transportation System mission using Space Shuttle Columbia, and was launched on October 22, 1992.
STS-54 was a NASA Space Transportation System mission using Space Shuttle Endeavour. This was the third flight for Endeavour, and was launched on January 13, 1993 with Endeavour returning to the Kennedy Space Center on January 19, 1993.
STS-60 was the first mission of the U.S./Russian Shuttle-Mir Program, which carried Sergei K. Krikalev, the first Russian cosmonaut to fly aboard a Space Shuttle. The mission used NASA Space Shuttle Discovery, which lifted off from Launch Pad 39A on February 3, 1994, from Kennedy Space Center, Florida. The mission carried the Wake Shield Facility experiment and a SPACEHAB module, developed by SPACEHAB Inc., into orbit, and carried out a live bi-directional audio and downlink link-up with the cosmonauts aboard the Russian space station Mir.
STS-73 was a Space Shuttle program mission, during October–November 1995, on board the Space Shuttle Columbia. The mission was the second mission for the United States Microgravity Laboratory. The crew, who spent 16 days in space, were broken up into 2 teams, the red team and the blue team. The mission also included several Detailed Test Objectives or DTO's.
STS-72 was a Space Shuttle Endeavour mission to capture and return to Earth a Japanese microgravity research spacecraft known as Space Flyer Unit (SFU). The mission launched from Kennedy Space Center, Florida on 11 January 1996.
STS-77 was the 77th Space Shuttle mission and the 11th mission of the Space Shuttle Endeavour. The mission began from launch pad 39B from Kennedy Space Center, Florida on 19 May 1996 lasting 10 days and 40 minutes and completing 161 revolutions before landing on runway 33. The defense and aerospace technology company L'Garde was responsible for the design and manufacture of the Antenna in the Inflatable Antenna Experiment, a key component of the STS-77 mission.
STS-79 was the 17th flight of Space Shuttle Atlantis, and the 79th mission of the Space Shuttle program. The flight saw Atlantis dock with the Russian space station Mir to deliver equipment, supplies and relief personnel. A variety of scientific experiments were also conducted aboard Atlantis by her crew. It was the first shuttle mission to rendezvous with a fully assembled Mir, and the fourth rendezvous of a shuttle to the space station.
STS-80 was a Space Shuttle mission flown by Space Shuttle Columbia. The launch was originally scheduled for October 31, 1996, but was delayed to November 19 for several reasons. Likewise, the landing, which was originally scheduled for December 5, was pushed back to December 7 after bad weather prevented landing for two days.
STS-83 was a NASA Space Shuttle mission flown by Columbia. It was a science research mission that achieved orbit successfully, but the planned duration was a failure due to a technical problem with a fuel cell that resulted in the abort of the 15 day duration. Columbia returned to Earth just shy of four days. The mission was re-flown as STS-94 with the same crew later that year.
STS-94 was a mission of the United States Space Shuttle Columbia, launched on 1 July 1997.
STS-87 was a Space Shuttle mission launched from Launch Complex 39B of the Kennedy Space Center on 19 November 1997. It was the 88th flight of the Space Shuttle and the 24th flight of Columbia. The mission goals were to conduct experiments using the United States Microgravity Payload (USMP-4), conduct two EVAs, and deploy the SPARTAN-201 experiment. This mission marked the first time an EVA was performed from Columbia. EVAs from Columbia were originally planned for STS-5 in 1982 and STS-80 in 1996, but were canceled due to spacesuit and airlock problems, respectively. It also marked the first EVA conducted by a Japanese astronaut, Takao Doi.
STS-95 was a Space Shuttle mission launched from Kennedy Space Center, Florida on 29 October 1998, using the orbiter Discovery. It was the 25th flight of Discovery and the 92nd mission flown since the start of the Space Shuttle program in April 1981. It was a highly publicized mission due to former Project Mercury astronaut and United States Senator John H. Glenn Jr.'s return to space for his second space flight. At age 77, Glenn became the oldest person to go into space, a record that remained unbroken for 23 years until 82-year-old Wally Funk flew on a suborbital flight on Blue Origin NS-16, launching on 20 July 2021, which in turn was broken by William Shatner at age 90 on 13 October 2021. Glenn, however, remains the oldest person to reach Earth orbit. This mission is also noted for inaugurating ATSC HDTV broadcasting in the U.S., with live coast-to-coast coverage of the launch. In another first, Pedro Duque became the first Spaniard in space.
