MISSION: STS-100 – 9th ISS Flight (6A) -Raffaello MPLM, SSRMS

VEHICLE: Endeavour/OV-105

LOCATION: Launch Pad 39A

KSC LAUNCH DATE/TIME: Apr. 19, 2001 at 2:41 p.m. EDT

KSC LANDING DATE/TIME: Apr. 30, 2001 at 10 a.m.

MISSION DURATION: 10 days, 19 hours and 19 minutes

CREW: Rominger, Ashby, Hadfield, Parazynski, Phillips, Guidoni, Lonchakov

ORBITAL INSERTION ALTITUDE and INCLINATION: 173 nautical miles/51.6 degrees

Shuttle Processing Note: The launch countdown for mission STS-100 began at 6
p.m. April 16, 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 are being loaded for flight
and the orbiter midbody umbilical unit will be demated later tonight.
Loading operations began about one hour late, allowing engineers to
troubleshoot a lighting dimmer switch in the crew module before clearing the
pad. The electrical box will be replaced tonight following cryogenic loading
with no impact to the remainder of the countdown.

Weather officials predict a 10 percent chance that weather could prohibit
Thursday’s launch. The forecast calls for scattered clouds at 4,000 feet
and broken at 25,000 feet; visibility at 7 miles; pad winds from the
northeast at 10 peaking to 15 knots; temperature at 72 degrees F; relative
humidity 43 percent and no chance of precipitation. The only concern is the
slight chance of return-to-launch-site crosswind violation. The 24-hour and
48-hour delay forecasts remain at a 10 percent chance of violation.

Upcoming Milestones:

Launch countdown starts – April 16 at 6 p.m.

Orbiter cryogenic reactant loading- April 17

Rotating Service Structure parked – April 18 at 6:30 p.m.

External Tank loading – April 19 (5:45 – 8:45 a.m.)
