STS-51-C was the 15th flight of NASA's Space Shuttle program, and the third flight of Space Shuttle Discovery. It launched on January 24, 1985, and made the fourth shuttle landing at the Shuttle Landing Facility at the Kennedy Space Center in Florida on January 27, 1985. STS-51-C was the first shuttle mission dedicated to the United States Department of Defense (DoD), and consequently many details remain classified. NASA reported that a satellite (USA-8) was deployed during the mission using an Inertial Upper Stage booster was deployed and met mission objectives. At just over three days, the mission was shorter in duration than most civilian missions and was the shortest of Discovery's career.
STS-28 was the 30th NASA Space Shuttle mission, the fourth shuttle mission dedicated to United States Department of Defense (DoD) purposes, and the eighth flight of Space Shuttle Columbia. The mission launched on August 8, 1989, and traveled 3,400,000 km (2,100,000 mi) during 81 orbits of the Earth, before landing on runway 17 of Edwards Air Force Base, California, on August 13, 1989. STS-28 was also Columbia's first flight since January 1986, when it had flown STS-61-C, the mission directly preceding the Challenger disaster of STS-51-L. The mission details of STS-28 are classified, but the payload is widely believed to have been the first SDS-2 relay communications satellite. The altitude of the mission was between 295 km (183 mi) and 307 km (191 mi).
STS-36 was a NASA Space Shuttle mission, during which Space Shuttle Atlantis carried a classified payload for the U.S. Department of Defense (DoD) into orbit. STS-36 was the 34th shuttle mission overall, the sixth flight for Atlantis, and the fourth night launch of the shuttle program. It launched from Kennedy Space Center, Florida, on February 28, 1990, and landed on March 4, 1990.
STS-41 was the 36th Space Shuttle mission and the eleventh mission of the Space Shuttle Discovery. The four-day mission had a primary objective of launching the Ulysses probe as part of the "International Solar Polar Mission" (ISPM).
STS-38 was a Space Shuttle mission by NASA using the Space Shuttle Atlantis. It was the 37th shuttle mission and carried a classified payload for the U.S. Department of Defense (DoD). It was the seventh flight for Atlantis and the seventh flight dedicated to the Department of Defense. The mission was a 4-day mission that traveled 3,291,199 km (2,045,056 mi) and completed 79 revolutions. Atlantis landed at Kennedy Space Center's Shuttle Landing Facility's runway 33. The launch was originally scheduled for July 1990 but was rescheduled due to a hydrogen leak found on Space ShuttleColumbia during the STS-35 countdown. During a rollback to the Orbiter Processing Facility Atlantis was damaged during a hail storm. The eventual launch date of November 15, 1990, was set due to a payload problem. The launch window was between 18:30 and 22:30 EST. The launch occurred at 18:48:13 EST. The mission ended with a landing at the Shuttle Landing Facility, marking the first time in five years that a mission returned to the Kennedy Space Center since STS-51-D. This also marked the first time Atlantis ended a mission at the Kennedy Space Center.
STS-39 was the twelfth mission of the NASA Space Shuttle Discovery, and the 40th orbital shuttle mission overall. The primary purpose of the mission was to conduct a variety of payload experiments for the U.S. Department of Defense (DoD).
STS-48 was a Space Shuttle mission that launched on September 12, 1991, from Kennedy Space Center, Florida. The orbiter was Space ShuttleDiscovery on her 13th flight. The primary payload was the Upper Atmosphere Research Satellite (UARS). The mission landed on September 18 at 12:38 a.m. EDT at Edwards Air Force Base on runway 22. The mission was completed in 81 revolutions of the Earth and traveled 3,530,369 km (2,193,670 mi). The 5 astronauts carried out a number of experiments and deployed several satellites. The total launch mass was 108,890 kg (240,060 lb) and the landing mass was 87,440 kg (192,770 lb).
STS-44 was a NASA Space Shuttle mission using Atlantis that launched on November 24, 1991. It was a U.S. Department of Defense (DoD) space mission.
STS-42 was a NASA Space Shuttle Discovery mission with the Spacelab module. Liftoff was originally scheduled for 8:45 EST on January 22, 1992, but the launch was delayed due to weather constraints. Discovery successfully lifted off an hour later at 9:52:33 EST on her 14th flight. The main goal of the mission was to study the effects of microgravity on a variety of organisms. The shuttle landed at 8:07:17 PST on January 30, 1992, on Runway 22, Edwards Air Force Base, California. STS-42 was the first of two flights in 1992 of Discovery, the second of which occurred during STS-53, which launched on December 2, 1992. The mission was also the last mission of the Space Shuttle Discovery to have a seven-member crew until STS-82, which was launched on February 11, 1997.
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-56 was a NASA Space Shuttle Discovery mission to perform special experiments. It was Discovery's 16th flight. The mission was launched from Kennedy Space Center, Florida, on April 8, 1993.
STS-51 was a NASA Space Shuttle Discovery mission that launched the Advanced Communications Technology Satellite (ACTS) in September 1993. Discovery's 17th flight also featured the deployment and retrieval of the SPAS-ORFEUS satellite and its IMAX camera, which captured spectacular footage of Discovery in space. A spacewalk was also performed during the mission to evaluate tools and techniques for the STS-61 Hubble Space Telescope (HST) servicing mission later that year. STS-51 was the first shuttle mission to fly a Global Positioning System (GPS) receiver, a Trimble TANS Quadrex. It was mounted in an overhead window where limited field of view (FoV) and signal attenuation from the glass severely impacted receiver performance. Full triple-redundant 3-string GPS would not happen until 14 years later with STS-118 in 2007.
STS-85 was the 23rd flight of Space Shuttle Discovery that performed multiple space science packages. It was launched from Kennedy Space Center, Florida, on 7 August 1997. A major experiment was the CRISTA-SPAS free-flyer which had various telescopes on board.
STS-64 was a Space Shuttle Discovery mission that was set to perform multiple experiment packages. It was Discovery's 19th flight. STS-64 was launched from Kennedy Space Center, Florida, on 9 September 1994, and landed back on 20 September 1994 at Edwards Air Force Base.
STS-66 was a Space Shuttle program mission that was flown by the Space Shuttle Atlantis. STS-66 launched on November 3, 1994, at 11:59:43.060 am EDT from Launch Pad 39-B at NASA's Kennedy Space Center. Atlantis landed at Edwards Air Force Base on November 14, 1994, at 10:33:45 am EST.
STS-67 was a human spaceflight mission using Space ShuttleEndeavour that launched from Kennedy Space Center, Florida on March 2, 1995.

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-91 was the 24th flight of Discovery, and the final Space Shuttle mission to the Mir space station. It was flown by Space Shuttle Discovery, and launched from Kennedy Space Center, Florida, on 2 June 1998.
James Shelton Voss is a retired United States Army colonel and NASA astronaut. During his time with NASA, Voss flew in space five times on board the Space Shuttle and International Space Station. He also served as deputy of Flight Operations for the Space Station Program Mission Integration and Operations Office. While participating in ISS Expedition 2, he and Susan Helms conducted an 8-hour and 56 minute spacewalk, the longest to date.
NASA Astronaut Group 10 was a group of 17 astronauts that were announced on May 23, 1984 and consisted of seven pilots and ten mission specialists. Although selected in 1984, no member of the group would fly until 1988 due to the Challenger disaster and the resulting grounding of the Space Shuttle fleet.
