Description:
STS-31 was the 35th Space Shuttle mission which launched the Hubble Space Telescope (HST) into Earth orbit using the Shuttle "Discovery", April 24-29 1990. Discovery's crew deployed the telescope on 25 April, and spent the rest of the mission tending to various scientific experiments and operating IMAX cameras to record the mission. With one exception, this was the 2nd flight for astronauts Loren J. Shriver (Commander), Charles F. Bolden Jr. (Pilot), Bruce McCandless (Mission Specialist), Steven A. Hawley (Mission Specialist, his 3rd mission), and Kathryn D. Sullivan (Mission Specialist). Discovery orbited Earth 80 times during the mission. To launch HST into an orbit that guaranteed longevity, Discovery soared to 370 miles, the record height permitted the crew to photograph Earth's large-scale geographic features not apparent from lower orbits. Motion pictures were recorded by 2 IMAX cameras, the results in the IMAX film "Destiny in Space." Experiments included a biomedical technology study, advanced materials research, particle contamination and ionizing radiation measurements, and a student science project on zero gravity effects on electronic arcs. The mission marked the flight of an 11 lb. human skull, the primary element of "Detailed Secondary Objective 469", a/k/a the In-flight Radiation Dose Distribution (IDRD) experiment, designed to examine penetration of radiation into the human cranium during spaceflight.

Selected by NASA in 1978, participated in 3 space flights: STS-51-C Pilot, 1985; STS-31 Commander, 1990; STS-46 Commander, 1992. CHARLES F. BOLDEN JR.

In 1984, during the 1st of his 2 Shuttle missions, made the 1st untethered free flight using the Manned Maneuvering Unit (MMU). In NASA Group 5, 1966, he and Group 5 colleague Don Lind were treated as scientist-astronauts by NASA due to their scientific experience and lack of test pilot experience highly valued by NASA managers which ultimately delayed their progression in flight rotation. CAPCOM on Apollo 11, on astronaut support crew for Apollo 14 doubling as CAPCPM. Reassigned to Skylab program, was backup Pilot for the space station's 1st manned mission, Skylab 3 and 4 CAPCOM. Co-investigator on the M-509 astronaut maneuvering unit experiment on Skylab which led to his collaboration on development of the MMU used during Shuttle EVAs. Mission specialist on STS-41-B (Challenger, 1984) and STS-31. KATHRYN D. SULLIVAN (b. 1951) Geologist, astronaut 1978-93, on 3 Shuttle missions, 1st US woman to walk in space.

She performed the 1st EVA on STS-41-G on Challenger in 1984, with mission specialist David Leestma performed 3.5h space walk and operated system designed to show that a satellite could be refueled in orbit. Dr. Sullivan was Payload Commander on STS-45. STS-31 Touchdown Cover, atamped 3 x 6 envelope postmarked Edwards Air Force Base, Cal., April 29 1990 on touchdown date, signed by 5 crew members.
