Mission highlights

The mission's primary objectives were the deployment of the European Space Agency's European Retrievable Carrier (EURECA) and the joint NASA/ASI (Italian Space Agency) Tethered Satellite System (TSS-1). EURECA was deployed a day later than scheduled because of a problem with its data handling system. Seven and a half hours after deployment, the spacecraft's thrusters were fired to boost EURECA to its planned operating altitude of around 500 km (310 mi). However, thruster firing was cut to six minutes from twenty-four minutes because of unexpected attitude data from the spacecraft. The problem was resolved, and EURECA was successfully boosted to its operational orbit on the mission's sixth day. TSS-1 deployment also was delayed one day because of the problems with EURECA. During deployment, the satellite reached a maximum distance of only 260 m (850 ft) from the orbiter instead of the planned 20 km (12 mi) because of a jammed tether line. After numerous attempts over several days to free the tether, TSS-1 operations were curtailed, and the satellite was stowed for return to Earth. It would be reflown in 1996 on STS-75, with astronauts Allen, Hoffman, Nicollier and Chang-Díaz also flying again on that mission.

Secondary payloads included the Evaluation of Oxygen Integration with Materials/Thermal Management Processes (EOIM-III/TEMP 2A), Consortium for Materials Development in Space Complex Autonomous Payload (CONCAP II and CONCAP III), IMAX Cargo Bay Camera (ICBC), Limited Duration Space Environment Candidate Materials Exposure (LDCE), Pituitary Growth Hormone Cell Function (PHCF), and the Ultraviolet Plume Instrument (UVPI). The mission was extended by a day in order to complete scientific objectives.

Spacelab was a reusable laboratory developed by European Space Agency (ESA) and used on certain spaceflights flown by the Space Shuttle.

It also carried the first African-American astronaut, Guion Bluford. The mission successfully achieved all of its planned research objectives, but was marred by the subsequent discovery that a solid-fuel rocket booster had almost malfunctioned catastrophically during the launch.

<span class="mw-page-title-main">STS-27</span> 1988 near-disastrous American crewed spaceflight to deploy Lacrosse 1

STS-27 was the 27th NASA Space Shuttle mission, and the third flight of Space Shuttle Atlantis. Launching on December 2, 1988, on a four-day mission, it was the second shuttle flight after the Space Shuttle Challenger disaster of January 1986. STS-27 carried a classified payload for the U.S. Department of Defense (DoD), ultimately determined to be a Lacrosse surveillance satellite. The vessel's heat shielding was substantially damaged during lift-off, and crew members thought that they would die during reentry. This was a situation that was similar to the one that would prove fatal 15 years later on STS-107. Compared to the damage that Columbia sustained on STS-107, Atlantis experienced more extensive damage. However, this was over less critical areas and the missing tile was over an antenna which gave extra protection to the spacecraft structure. The mission landed successfully, although intense heat damage needed to be repaired.

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).

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-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.
