  • TARGET KSC LANDING DATE/TIME: Feb. 22, 2000 at 4:38 p.m. EST
  • LAUNCH WINDOW: 2 hours and 10 minutes
  • MISSION DURATION: 11 days, 4 hours and 8 minutes

Work in progress: Preparation continues on schedule today for the launch of Space Shuttle Endeavour this Friday at 12:30 p.m. EST. Replacement of the global positioning system box located inside Endeavour’s crew module concluded yesterday and tests of the new unit are complete. The orbiter’s onboard storage tanks were loaded with cryogenic reactants last night and no significant issues are being worked by the KSC launch team at this time.

Today, Endeavour’s three main engines will be prepared for propellant loading operations. The orbiter’s communication systems will be activated this morning and this afternoon flight crew equipment late stow operations begin. The Rotating Service Structure will move to the park position at about 6:30 p.m., revealing the entire Shuttle for the first time since the last launch attempt.

The official forecast indicates an 90 percent chance that weather will be favorable for Friday’s launch attempt. The forecast calls for clouds to be scattered at 3,000 and 25,000 feet; visibility at 7 miles; southerly launch pad winds at 12 peaking to 18 knots; temperature at 75 degrees F; relative humidity at 45 percent; dew point at 52 degrees F; and zero chance of precipitation. The only concern is for the possibility of cross wind violation at the Shuttle Landing Facility. The 24-hour delay forecast indicates a 60 percent chance of favorable weather on Feb. 12.

Processing Milestones (target dates only):

  • Rotating Service Structure retracted (Feb. 10 at about 6:30 p.m.)
  • External tank loading (Feb. 11, 4:10 a.m. ñ 7:10 a.m.)
