Marshall Space Flight Center Marshall Space Flight Center, Alabama December 4, 1985. Proceedings of a symposium held at NASA George C. It was the problem with the O-rings on the left solid rocket motor (SRM) on this launch (SRM-16A) that prompted Roger Boisjoly to write a memo to Bob Lund about the potential for the O-rings to cause catastrophic failure. Morton-Thiokol engineers told Lind after the mission that "you came within three-tenths of one second of dying". While participating in the investigation into the destruction of Challenger during STS-51L in 1986, Overmyer discovered that a problem with the shuttle's O-rings, similar to that which led to the disaster, had emerged during the launch of STS-51B. EDT on May 6, 1985, after a mission lasting 7 days, 0 hour, 8 minutes, and 46 seconds.Ĭonnection to the Challenger disaster NUSAT deployed successfully, but GLOMR did not deploy, and was returned to Earth.Ĭhallenger landed safely at Edwards Air Force Base at 12:11:04 p.m. These were NUSAT (Northern Utah Satellite) and GLOMR (Global Low Orbiting Message Relay satellite). Two Getaway Special (GAS) experiments required that they be deployed from their canisters, a first for the program. On the mission, Spacelab carried 15 primary experiments, of which 14 were successfully performed. The crew members in orbit were supported 24 hours a day by a temporary Payload Operations Control Center, located at the Johnson Space Center. Two squirrel monkeys and 24 rats were flown in special cages, the second time American astronauts flew live non-human mammals aboard the shuttle. The crew operated around the clock in two 12-hour shifts. The gravity gradient attitude of the orbiter proved quite stable, allowing the delicate experiments in materials processing and fluid mechanics to proceed normally. Spacelab's capabilities for multi-disciplinary research in microgravity were successfully demonstrated. STS-51-B was the second flight of the European Space Agency (ESA)'s Spacelab pressurized module, and the first with the Spacelab module in a fully operational configuration. Similar to the previous Spacelab mission ( STS-9), the crew was divided roughly in half to cover 12-hour shifts, with Overmyer, Lind, Thornton and Wang forming the Gold team, and Gregory, Thagard and van den Berg as the Silver team. Average age of 48.6 was the oldest for an American space mission. Wang, of the Jet Propulsion Laboratory (JPL), both payload specialists.

The white board surrounding it all has the appearance of a space suit helmet, with the names of the two respective teams grouped around them on a round band encircling the insignia, and the two mission specialists on an added section below. Behind the orbiter, the contours of Pegasus can be seen, as a reference to the European Space Agency (ESA). The seven crewmembers are represented by the 7 stars on the patch, that indirectly refer to the Mercury Seven as a nod to their legacy. The orbiter rides over the American flag. The mission insignia features the Challenger with her payload doors open, to show the onboard Spacelab 3. The shuttle landed successfully on May 6, 1985, after a week-long mission.Ĭrew seating arrangements Seat When STS-51-E was canceled, Challenger was remanifested with the STS-51-B payloads. The shuttle was rolled back when a timing issue emerged with the TDRS-B satellite. Challenger was initially rolled out to the pad to launch on the STS-51-E mission. The launch of Challenger on April 29, 1985, was delayed by 2 minutes and 18 seconds, due to a launch processing failure. STS-51-B was the 17th flight of the NASA Space Shuttle program and the seventh flight of Space Shuttle Challenger.
