Space shuttle columbia wiki9/4/2023 ![]() ![]() The cylindrical pod and surrounding black tiles on the orbiter's vertical stabilizer housed an imaging system, designed to map thermodynamic conditions during reentry, on the surfaces visible from the top of the tail fin. The Shuttle Lee-side Temperature Sensing (SILTS) infrared camera package made its second flight aboard Columbia on this mission. This filler material was the same material that was removed during a spacewalk during STS-114, the Space Shuttle's post- Columbia disaster Return to Flight mission, in 2005. A detailed report identified protruding gap filler as the likely cause. Post-flight analysis of STS-28 discovered unusual heating of the thermal protection system (TPS) during re-entry, caused by an early transition to turbulent plasma flow around the vehicle. An RCS heater also malfunctioned during the flight. ĭuring the flight, the crew shut down a thruster in the reaction control system (RCS) after receiving indications of a leak. This experiment, which also flew on STS-36 and STS-31, was located in the shuttle's mid-deck lockers on all three flights, recording radiation levels at different orbital inclinations. Hundreds of thermoluminescent dosimeters were mounted in the skull's layers to record radiation levels at multiple depths. The female skull was seated in a plastic matrix, representative of tissue, and sliced into ten layers. ![]() This joint NASA/DoD experiment was designed to examine the penetration of radiation into the human cranium during spaceflight. The mission marked the first flight of a 5 kg (11 lb) human skull, which served as the primary element of "Detailed Secondary Objective 469", also known as the In-flight Radiation Dose Distribution (IDRD) experiment. These satellites had the same bus design as the LEASAT satellites deployed on other shuttle missions, and were likely deployed in the same fashion. Later reports, and amateur satellite observations, suggest that USA-40 was instead a second-generation Satellite Data System (SDS) relay, similar to those likely launched on STS-38 and STS-53. Early reports speculated that STS-28's primary payload was an Advanced KH-11 photo-reconnaissance satellite. EDT.ĭuring STS-28, Columbia deployed two satellites: USA-40 and USA-41. Space Shuttle Columbia (OV-102) lifted off from Pad 39B, Launch Complex 39 at Kennedy Space Center, Florida, on August 8, 1989. Mission summary Launch of STS-28 STS-28 landing As STS-51-L was designated STS-33, future flights with the STS-26 through STS-33 designators would require the R in their documentation to avoid conflicts in tracking data from one mission to another.Ĭrew seating arrangements Seat Official documentation for that mission contained the designator STS-28 throughout. ![]() The mission was officially designated STS-28R as the original STS-28 designator belonged to STS-51-J, the 21st Space Shuttle mission. The altitude of the mission was between 295 km (183 mi) and 307 km (191 mi). The mission details of STS-28 are classified, but the payload is widely believed to have been the first SDS-2 relay communications satellite. ![]() 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 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 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. ![]()
