Payload:

Space Station Assembly Flight ISS-09-6A (Raffaello MPLM-1, Racks/SLP, Canadarm2(SSRMS,SPDM), LCA,RU, UHF Antenna)

Mission Objectives:

The highest priority objectives of the flight are the installation,

activation and checkout of the robotic arm on the station. The

operation of the arm is critical to the capability to continue

assembly of the International Space Station and to attach a new

airlock to the station on the subsequent shuttle flight, mission

STS-104, planned for launch in June. A final component of the

Canadian Arm is the Mobile Base System (MBS) that will be installed

onboard the station during the UF-2 STS-111 flight.

Other major objectives for Endeavour's mission are to berth the

Raffaello logistics module to the station, activate it, transfer

cargo between Raffaello and the station, and reberth Raffaello in the

shuttle's payload bay. Raffaello is the second of three Italian Space

Agency-developed multi-purpose logistics modules to be launched to

the station. The Leonardo module was launched and returned on the

last shuttle flight, STS-102, in March.

Remaining objectives include the transfer of other equipment to the

station such as an Ultra-High Frequency communications antenna and a

spare electronics component to be attached to the exterior during

space walks. Finally, the transfer of supplies and water for use

aboard the station, the transfer of experiments and experiment racks

to the complex, and the transfer of items for return to Earth from

the station to the shuttle are among the objectives.

Endeavour also is planned to boost the station's altitude and perform

a flyaround survey of the complex, including recording views of the

station with an IMAX cargo bay camera.

Launch:

April 19, 2001 2:41 p.m. EDT. Launch occured ontime at the opening of a 4.5 minute launch window. SSME cutoff ontime at T+8 minutes 39 seconds. Shuttle liftoff weight 4,521,931 lbs.

On Tuesday, April 17, 2001, engineers completed troubleshooting a faulty lighting dimmer switch on the flight deck of the crew module. The electrical box was successfully replaced overnight following cryogenic loading. Loading of the orbiter's onboard cryogenic storage tanks is now complete, and technicians are working no further problems at the pad at this time. (Reference KSC Shuttle Status 4/18/2001)

On Monday, April 16, 2001, the launch countdown for mission STS-100 began at 6 p.m. as scheduled. Preparation continues toward a launch of Space Shuttle Endeavour and the seven-member flight crew at 2:41 p.m. Thursday. The orbiter's onboard cryogenic storage tanks were then loaded for flight and the orbiter midbody umbilical unit demated. Loading operations began about one hour late, allowing engineers to troubleshoot a lighting dimmer switch in the crew module before clearing the pad. (Reference KSC Shuttle Status 4/17/2001)

Space Shuttle Endeavour rolled out of the Vehicle Assembly Building today at about 9:50 a.m. Solid rocket booster closeout inspections slightly delayed first motion, and Endeavour is now expected to arrive at the pad before 4 p.m. Once at the pad, routine launch pad validations commence, verifying all vehicle and facility interfaces. (Reference KSC Shuttle Status 3/22/2001)

Shuttle orbiter Endeavour departed OPF bay 2 Saturday at about 9:26

a.m. headed for the VAB. Orbiter and external tank mating activities

are under way and the Shuttle Interface Test will conclude on

Wednesday. The full Space Shuttle stack is scheduled to roll out of

VAB high bay 3 at 7 a.m. on Thursday, March 22, and should arrive at

Launch Pad 39B by about 1 p.m.
