KENNEDY SPACE CENTER SPACE SHUTTLE STATUS REPORT FRIDAY, OCTOBER 4, 1996 (4:00 PM) KSC Public Affairs Contact: Bruce Buckingham (fax 407-867-2692) E-mail: Bruce.Buckinghamfirstname.lastname@example.org MISSION: STS-80 -- WAKE SHIELD FACILITY-3 and ORFEUS-SPAS-2 (image) VEHICLE: Columbia/OV-102 LOCATION: Orbiter Processing Facility bay 1 TARGET LAUNCH DATE/TIME: Nov. 8 at 2:47 p.m. (EST) LAUNCH WINDOW: 2 hours, 30 minutes TARGET KSC LANDING DATE/TIME: Nov. 24 at 7:31 a.m. MISSION DURATION: 16 days CREW: Cockrell, Rominger, Jernigan, Jones, Musgrave ORBITAL ALTITUDE and INCLINATION: 219 statute miles/28.45 degrees NOTE: Shuttle managers today decided to delay the rollout of Columbia to the Vehicle Assembly Building to allow time for the replacement of orbiter windows no. 3 and no. 4, the two forward-most windows. The windows will be replaced while engineers complete an analysis of the possible effects of hazing and pitting on windows that have been in place for a high number of flights. One of the windows being replaced has flown eight times and the other seven times. The new engineering analysis, although still in a preliminary stage, may find that windows that have seen a substantial amount of hazing from flying many times, could tend to fracture more easily. To be conservative with the management of Columbia's flight and allow time for the engineering study to progress, managers opted to replace the two window panes with new panes that have not flown before. The concern is with only the outermost pane, called the thermal pane, which is 0.625-inch thick. Two other window panes, a center pane that is 1.3-inches thick and an inner pane that is 0.625-inch thick, are not a concern. Any possible actions regarding other windows on other orbiters are still under evaluation, and a final decision on them likely will not be made until the engineering study has reached a final conclusion. The work to replace the windows will be performed in the OPF and is expected to add about eight days to Columbia's OPF schedule. Managers are evaluating the contingency time in the overall STS-80 schedule and expect to decide on a possible new target launch date next week. KEY STS-80 OPERATIONAL MILESTONES (dates are target only): Roll Columbia to Vehicle Assembly Building and mate with external tank(TBD) Deliver payload to Pad 39B (TBD) Rollout to Pad 39B (TBD) Terminal Countdown Demonstration Test (TBD) MISSION: STS-81 -- 5th MIR DOCKING & SPACEHAB DM (image) VEHICLE: Atlantis/OV-104 LOCATION: Orbiter Processing Facility Bay 3 TARGET KSC LAUNCH DATE/TIME: Jan. 12, 1997 at about 4:17 a.m. (EST) LAUNCH WINDOW: 7-10 minutes TARGET KSC LANDING DATE/TIME: Jan. 21, 1997 at about 8:40 a.m. MISSION DURATION: 9 days (+1) CREW: Baker, Jett, Grunsfeld, Ivins, Wisoff, Linenger (up) Blaha (down) ORBITAL ALTITUDE and INCLINATION: 184 statute miles/51.6 degrees NOTE: Work today includes preparations for deservicing the auxiliary power units. The controller for auxiliary power unit (APU) no. 2 has been removed and sent to the vendor for analysis. The APU itself will be removed early next week and sent to the vendor. The other two APUs will be removed later in the week. Solid rocket booster (SRB) stacking operations continue in the VAB. KEY STS-81 OPERATIONAL MILESTONES (dates are target only): Remove Space Shuttle main engines (Oct. 24) Install Space Shuttle main engines (Nov. 5) MISSION: STS-82 -- HUBBLE SPACE TELESCOPE SERVICING MISSION-2 VEHICLE: Discovery/OV-103 LOCATION: Orbiter Processing Facility Bay 2 TARGET LAUNCH DATE/TIME: Feb. 13, 1997 at 2:59 a.m. LAUNCH WINDOW: 61 minutes TARGET KSC LANDING DATE/TIME: Feb. 23, 1997 at 1:35 a.m. MISSION DURATION: 9 days, 22 hours CREW: Bowersox, Horowitz, Lee, Hawley, Harbaugh, Smith, Tanner ORBITAL ALTITUDE and INCLINATION: 360 statute miles/28.45 degrees NOTE: Midbody close-outs and water coolant loop servicing continue today. Interface verification tests for the forward reaction control system are also under way today. KEY OPERATIONAL MILESTONES (dates are target only): Install Space Shuttle main engines (Oct. 14) Install left-hand orbital maneuvering system pod (Oct. 21) NOTE: Yesterday, in KSC's Hypergol Maintenance Facility (HMF), one of the orbital maneuvering system pods scheduled for use on Columbia on Mission STS-83 was inadvertently deluged with water from a facility fire protection system. At this time, no determination has been made about damage to the pod and it is not anticipated that mission STS-83, set for launch in March 1997, will be delayed. No injuries were reported but an investigation board has been formed to determine the circumstances which led to the release of the water and the extent of the damage it caused to the pod. SPECIAL NOTE: An investigation of the wrench found inside the solid rocket booster (SRB) used on Atlantis' mission STS-79 has been completed. The Anomaly Resolution Team formed immediately after the 7/16-inch combination wrench was found in the right-hand SRB's forward skirt determined that one of the possible sources for this wrench was USBI Co. assembly operations. The condition of the wrench and data available on the wrench did not allow a more specific determination. As a result, USBI is proceeding with enhancements to their tool-control system and hardware inspections to preclude possible recurrence of this problem in the future. Flight hardware already transferred for the next two flights is being reinspected using enhanced procedures. Tool-control enhancements include such things as unique tool markings, shadow boxing tool boxes, and increased inventory checks. Inspection improvements include additional lighting, graphics to emphasize and assist with difficult to inspect areas, and further augmentation of boroscopes where use of mirrors is difficult. The 1.77-ounce wrench did not cause any damage to components in the booster structure. Analysis also confirmed that the wrench could not have caused any damage to the critical components contained in the structure.
