STS-80
STS-80 was a Space Shuttle mission flown by Space Shuttle "Columbia". The launch was originally scheduled for 31 October 1996, but was delayed to 19 November for several reasons. Likewise, the landing, which was originally scheduled for 5 December, was pushed back to 7 December after bad weather prevented landing for two days. It was the longest Shuttle mission ever flown at 17 days, 15 hours, and 53 minutes. Although two spacewalks were planned for the mission, they were both canceled after problems with the airlock hatch prevented astronauts Tom Jones and Tammy Jernigan from exiting the orbiter. Mission  payload. "Columbia" brought with it two free floating satellites, both of which were on repeat visits to space. Also, a variety of equipment to be tested on two planned spacewalks was part of the payload. These would have been used to prepare for construction of the International Space Station. Included in the Shuttle's payload were Scientific projects. "Columbia" carried into orbit two satellites that were released and recaptured after some time alone. The first was the Orbiting and Retrievable Far and Extreme Ultraviolet Spectrometer-Shuttle Pallet Satellite II (ORFEUS-SPAS II). The main component of the satellite, the ORFEUS  telescope, had two spectrographs, for far and extreme ultraviolet. Another spectrograph, the Interstellar Medium Absorption Profile Spectrograph, was also on board the satellite. Several payloads not relevant to astronomy rounded out the satellite. It performed without problems for its flight, taking 422 observations of almost 150 astronomical bodies, ranging from the moon to extra-galactic stars and a quasar. Being the second flight of ORFEUS-SPAS II allowed for more sensitive equipment, causing it to provide more than twice the data of its initial run. Also deployed from "Columbia" was the Wake-Shield Facility (WSF), a satellite that created an  ultra-vacuum behind it, allowing for the creation of semiconductor thin films for use in advanced electronics. WSF created seven films before being recaptured by "Columbia's" robotic arm after three days of flight. The craft was on its third mission, including STS-60, when hardware problems prevented it from deploying off the robotic arm. Wake Shield was designed and built by the Space Vacuum Epitaxy Center at the University of Houston in conjunction with its industrial partner, Space Industries, Inc. Another inclusion was a Space Experiment Module (SEM). The SEM included student research projects selected to fly into space. This  was the first flight of the program. Among the experiments conducted were analysis of bacteria growth on food in orbit, crystal growth in space, and microgravity's effect on a pendulum. NIH.R4 was an experiment conducted for the National Institute of Health and Oregon Health Sciences University. It was designed to test the effects of spaceflight on circulation and vascular constriction. Biological Research in Canister (BRIC) explored gravity's effects on tobacco and tomato seedlings. Visualization in an Experimental Water Capillary Pumped Loop (VIEW-CPL) was conducted to test a new idea in thermal spacecraft management. The Commercial MDA ITA  Experiment were a variety of experiments submitted by high school and middle school students sponsored by Information Technology Associates. Mission background. Astronauts were selected for the mission on 17 January 1996. Stacking of the Solid Rocket Boosters (SRBs) began 9 September 1996. On 18 September, the launch date was bumped back from no earlier than (NET) 31 October to 8 November. Payload doors were closed on 25 September. The following day, the External fuel tank was mated to the SRBs inside the Vehicle Assembly Building. Further progress was delayed while two windows on the orbiter were replaced; NASA feared that  they might be susceptible to breakage after seven and eight flights. "Columbia" was rolled over to the VAB on 9 October to begin final assembly preparations. On 11 October, "Columbia" was mated with the external fuel tank, and the payload was delivered and transferred. Rollout to Pad 39B occurred on 16 October, which was followed by flight readiness checks of the main propulsion system. After a Flight Readiness Review on 28 October, an additional FRR was requested to further analyze the Redesigned Solid Rocket Motor (RSRM) due to nozzle erosion that occurred on STS-79; on the 29th, a fuel pump  failed, delaying the fueling process of "Columbia". The erosion problem led to a week long delay instituted on 4 November. A launch date of 15 November was set, contingent on a successful Atlas launch two days prior. The forecast of bad weather pushed the launch back even further, to a date of 19 November. Wake-up calls. NASA began a tradition of playing music to astronauts during the Gemini program, which was first used to wake up a flight crew during Apollo 15. Each track is specially chosen, often by their families, and usually has a special meaning to an  individual member of the crew, or is applicable to their daily activities.
