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: Countdown activities continue today for launch at
2:41 p.m. Thursday, April 19.

Yesterday, 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.

The rotating service structure will be retracted away from the Shuttle
vehicle at 6:30 p.m. today as preparations continue for tanking operations
set to begin as early as 5:15 a.m. tomorrow. Loading of the external tank
with about 500,000 gallons of cryogenic propellants should be completed
about three hours later.

The seven-member crew has been at KSC since Monday, and today they are
completing final flight plan reviews in anticipation of launch tomorrow.

Weather officials continue to predict only a 10 percent chance that weather
could prohibit Thursday’s launch attempt. The forecast calls for scattered
clouds at 4,000 feet and 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 53 percent and no chance of precipitation. The only
concern is the slight chance of a crosswind violation at KSC’s Shuttle
Landing Facility. The 24-hour and 48-hour delay forecasts remain at a 10
percent chance of violation.
