The Multipurpose Logistics Module, or MPLM, will carry experiment

racks and three stowage and resupply racks to the station. The

mission will also install a component of the Canadian Arm called the

Mobile Base System (MBS) to the Mobile Transporter (MT) installed

during STS-110. This completes the Canadian Mobile Servicing System,

or MSS. The mechanical arm will now have the capability to

"inchworm" from the U.S. Lab fixture to the MSS and travel along the

Truss to work sites.

Launch:

June 5, 2002 5:22:49 p.m. EDT (21:22:49 GMT) The Launch Window was 4 minutes, 39 seconds.

On Wednesday, June 5, 2002, launch countdown has been proceeding on schedule with no weather constraints. At 4 p.m. EDT final cabin vents tests were complete and the hatch verified closed for flight. At 4:18 p.m. the countdown clock came out of the planned 10 minute hold at the T-minus 20 minute mark. At 4:29 p.m. the countdown clock entered into the T-minus 9 minute mark for a planned 45 hold. At 5:15 p.m. EDT the countdown clock came out of the T-minus 9 minute hold. At 5:17 p.m the Orbiter Access Arm (OAA) was retracted. Launch occured at the start of the launch window.

On Friday, May 31, 2002, at the tanking meeting, mission managers postponed today's launch attempt for Space Shuttle Endeavour. Forecasters predicted an 80 percent chance of weather prohibiting today's launch due to severe thunderstorms and rain showers within the vicinity of the launch pad throughout the day. At the Pad, workers will move the Rotating Service Structure back around the Shuttle for protection from approaching storms. A meeting will be held at 7:30 p.m. tonight to assess Saturday's weather forecast and determine if a tanking meeting will be held tomorrow.

On Thursday, May 30, 2002, tanking operations began at 10:32 a.m. EDT and was completed at 1:26 p.m. Shortly after 4:00 p.m. the crew departed the crew quarters, traveled to the launch pad and began the process of entering Endeavour. At 6:30 p.m., at the T-minus 20 minute and holding mark, the hatch was closed and latched for flight. The countdown proceeded smoothly with the weather as the primary concerns. There were also issues related to some readings from a GN2 pressure regulator on the left OMS pod. At 6:41 p.m. the launch manager made a call to extend the 10 minute hold at the T-minus 20 minute mark to allow for additional troubleshooting of the OMS GN2 regulator. Troubleshooting confirmed the OMS system was functioning properly and the countdown clock picked up to the T-minus 9 minute mark. At 7:21 p.m. EST, the planned 19:44:26 EDT launch attempt for 5/30/02 was scrubbed due to weather concerns with a 24 hour launch scrub turn-around and a new T-0 set for 7:22p.m. EST

On Wedesday, May 29, 2002, The launch of Space Shuttle Endeavour has been confirmed for Thursday, May 30, at the preferred launch time of 7:44:26 p.m. EDT (23:44:26 GMT). All remaining countdown activities continue on schedule. The planar launch window on Thursday extends from 7:39:27 - 7:49:25 p.m. EDT (23:39:27 - 23:49:25 GMT) with the preferred launch time reflecting a flight day three rendezvous and docking with the International Space Station. The launch window will be updated to coincide with the latest orbital position of the Space Station and will be announced at the T-9 minute hold. (Reference KSC Press Release 51-02).

On Friday, May 24, 2002, during routine testing, technicians observed that temperatures in the Auxiliary Power Unit's coolant system (water spray boiler No. 3) did not reach proper levels in the times required. Workers will enter the aft engine compartment tonight to inspect the water spray boiler and look for possible leaks. The system will be recycled and managers will determine if additional work is required. At this time, no impact to the launch schedule is expected. At the pad in the orbiter's payload bay, late-stow items are being placed in the Multi-Purpose Logistics Module today. Launch countdown preparations are beginning, with the countdown scheduled to pick up early next week. (Reference KSC Shuttle Status 5/24/2002)

On May 14, 2002, the crew of STS-111 arrived to participate in the Terminal Countdown Demonstration Test (TCDT) in preparation for the launch on May 30. As the astronauts were taking part in TCDT, mission managers met for the Flight Readiness Review and determined there were no issues or constraints at this time for Endeavour's launch next week. Late stow items are scheduled to placed in the Leonardo and Extravehicular Mobility Unit installation and checkout is in work. (Reference KSC Shuttle Status 5/20/02)

At 10:55 a.m. EDT, the second landing opportunity for KSC on June 19, 2002 was waved off due to weather and Edwards AFB was selected. The deorbit burn was done at 12:50 a.m. EDT to land on the first of 3 landing opportuntities.

The landing opportunity for STS-111 on 6/18/02 was waved off due to the threat of thunderstorms and rain showers within 55.6 kilometers (30 nautical miles) of the Shuttle Landing Facility at Kennedy Space Center, Fla. Earlier in the day, controllers decided to pass on the two opportunities at Edwards Air Force Base today due to Wednesday's weather forecast at Kennedy that calls for more favorable conditions.

The first landing opportunities for STS-111 on 6/17/02 at 12:59 a.m. EDT (1659 GMT) was waived off at 11:10 EDT due to weather. It would have required a de-orbit burn at 11:51 a.m. EDT (1551 GMT). The second landing opportunity was to be at 2:36 p.m. EDT (1836 GMT), with the de-orbit burn at 12:30 p.m. CDT (1730 GMT). It was also waived off.
