Click here for Additional Info on STS-96

STS-96 is a logistics and resupply mission for the International Space Station. It will be the first flight to dock to the International Space Station. The SPACEHAB double module will carry internal and resupply cargo for station outfitting.

The Integrated Cargo Carrier (ICC) will carry the Russian cargo crane, known as STRELA, which will be mounted to the exterior of the Russian station segment, the SPACEHAB Oceaneering Space System Box (SHOSS) and a U.S. built crane called the ORU Transfer Device (OTD).

Other payloads on STS-96 are the Student Tracked Atmospheric Research Satellite for Heuristic International Networking Equipment (STARSHINE), the Shuttle Vibration Forces Experiment (SVF) and the Orbiter Integrated Vehicle Health Monitoring - HEDS Technology Demonstration (IVHM HTD).

The STARSHINE satellite consists of an inert, 19-inch hollow sphere covered by 1,000 evenly-distributed, flat, polished mirrors, each 1 inch in diameter. The payload consists of the STARSHINE satellite, integrated with the Pallet Ejection System (PES), then mounted inside a lidless carrier. The HH equipment consists of one HH Lightweight Avionics Plate (LAP), then mounted inside a lidless carrier. Additional HH equipment consists of one Hitchhiker Ejection System Electronics (HESE), one 5.0 cubic-foot HH canister, and one Adapter Beam Assembly (ABA). The purpose of the mission is to train international student volunteer observers to visually track this optically reflective spacecraft during morning and evening twilight intervals for several months, calculate its orbit from shared observations, and derive atmospheric density from drag-induced changes in its orbit over time.

The Shuttle Vibration Forces (SVF) Experiment will provide flight measurements of the vibratory forces acting between an aerospace payload and its mounting structure. The force transducers will be incorporated into four custom brackets which will replace the existing brackets used to attach the 5 ft standard canister to the side wall GAS adapter beam. The payload will be activated automatically by the Orbiter Lift-off vibration and will operate for approximately 100 seconds. STS-96 will be the second flight of the SVF experiment

The purpose of the Orbiter Integrated Vehicle Health Monitoring- HEDS Technology Demonstration (IVHM HTD) is to demonstrate competing modern, off-the-shelf sensing technologies in an operational environment to make informed design decisions for the eventual Orbiter upgrade IVHM. The objective of IVHM is to reduce planned ground processing, streamline problem troubleshooting (unplanned ground processing), enhance visibility into systems operation and improve overall vehicle safety.

Launch:

Launched May 27, 1999 6:49a.m. EDT. Window was 5-10 min.

On Thursday, May 27, 1999, at 1:49 a.m., the flight crew ate breakfast in the dining room of the astronauts quarters in the Operations and Checkout Building (O&C) and received a weather briefing at 2:19 a.m. EDT. The crew then suited up and departed for Launch Pad 39-B at 3:05 a.m. EDT. At 3:30 a.m. EDT the crew entered the white room and began boarding the Discovery. At 4:14 a.m. EDT boarding was complete and by 5:36 a.m. EDT the hatch was closed and locked for flight. At 6:15 a.m. EDT, with countdown clock at the hold at the T-minus 9 minute mark, the only concern being tracked was a sailboat in the SRB recovery area. It has been contacted and will be out of the area shortly. At 6:33 a.m. EDT, after a final poll of the launch team, the mission management team gave a clear to launch. The countdown clock came out of the T-minus 9 minute mark at 6:41 a.m. EDT. At 6:43 a.m. the Orbiter Access Arm (OAA) was retracted. Liftoff at 6:49 a.m. EDT. Good SRB separation at 6:52 a.m EDT.

On Wednesday, May 26, 1999 Preparations for launch of Space Shuttle Discovery on Thursday continue as scheduled. The Rotating Service Structure was retracted away from the vehicle and placed in launch configuration early this afternoon. Earlier today, the orbiter's inertial measurement units were activated and the flight crew's equipment was stowed in the orbiter. The crew began final preparations for launch when they awoke at 6:30 p.m. They are scheduled to begin donning their launch and entry suits at 2:19 a.m. tomorrow and depart for the launch pad at about 3 a.m. At 9:30p.m. EDT, the mission management team gave the go to begin loading of the 528,000 gallons of cryogenic propellants into the Shuttle's external tank. The 3 hour loading operations began at 9:54 p.m. EDT as the launch team came out of the planned 2 hour hold at the T-minus 6 hour mark. (Reference KSC Shuttle Status 5/26/1999)

On Monday, May 24, 1999, the launch countdown for STS-96 began on schedule at 9 a.m. EDT at the T-43 hour mark. Over the weekend, workers completed ordnance connections and pressurization of Discovery's maneuvering system and reaction control system. Yesterday morning, aft compartment close-outs concluded and aft confidence checks are in work today. Mating of the orbiter midbody umbilical unit is also complete. This morning, pyrotechnic initiator controller testing began. (Reference KSC Shuttle Status 5/24/1999)

On Sunday, May 26, 1999, at about 11 p.m. EDT the STS-96 flight crew arrived at KSC's Shuttle Landing Facility. In the three days prior to launch they will undergo routine medical exams and participate in standard orbiter and payload familiarization activities. The commander and pilot will also take practice flights in the Shuttle Training Aircraft and T-38 jets this week. (Reference KSC Shuttle Status 5/24/1999)

On Wednesday, May 20, 1999 , shuttle managers today confirmed May 27 as the launch date for Shuttle mission STS-96. Based on an updated weather forecast and prompt repairs of Discovery's hail-damaged external tank foam insulation, managers decided to transfer Space Shuttle Discovery back to Launch Pad 39B Thursday morning. Shuttle close-out work will commence once Discovery arrives at the pad and will conclude in time for May 27 launch. The launch countdown begins at 9 a.m. on Monday, May 24. Discovery's external tank repairs were completed today and tonight workers will remove access platforms and scaffolding in preparation for Thursday's move to the pad. If weather continues to cooperate, Discovery will begin moving out of VAB high bay 1 about 2 a.m. tomorrow and will be hard down at Pad 39B by midday. (Reference KSC Shuttle Status 5/19/1999)

On Monday, May 17, 1999, technicians completed evaluations on Discovery's hail-damaged external tank foam insulation and began repair efforts. Having much closer access than what is available at the launch pad, inspections in the VAB revealed a total of 648 divots in the tank's outer foam. Managers consider 189 of the divots acceptable to fly without repair. Blending or sanding work is required for 211 hits and 248 divots will be patched with new foam. The current schedule indicates that foam repair efforts will be complete tomorrow. (Reference KSC Shuttle Status 5/18/1999)

On Thursday, May 13, 1999, NASA Shuttle managers decided to move the launch date from May 20, 1999 at 9:32a.m. EDT to May 27, 1999 no earlier than 6:48a.m EDT. The decision was made to roll Space Shuttle Discovery back to the Vehicle Assembly Building to complete repair work on the hail-damaged external tank foam insulation. After much evaluation, managers determined that necessary repair work could not be performed at Launch Pad 39B due to limited access to damaged areas. Managers expect Discovery's move toward the VAB to begin early Sunday morning, May 16. Current work plans indicate that the foam repairs will take 2 to 3 days, allowing Discovery to roll back to Pad 39B by midweek. Managers expect the Shuttle to be ready for launch no earlier than May 27. (Reference KSC Shuttle Status 5/13/1999)
