LAUNCH MINUS 1 DAY

MISSION: STS-70 -- TDRS-G

VEHICLE: Discovery/OV-103
LOCATION: Pad 39-B
LAUNCH DATE/TIME: July 13 at 9:41 a.m. EDT
LAUNCH WINDOW: 2 hours, 30 minutes
KSC LANDING DATE/TIME: July 21 at 7:51 a.m.
MISSION DURATION: 7 days, 22 hours
CREW SIZE: 5
ORBITAL ALTITUDE and INCLINATION: 184 statute miles/28.45 degrees

NOTE: The countdown for launch of Discovery on Mission STS-70 remains
on schedule to occur at the opening of a 2 1/2 hour launch window at
9:41 a.m. on Thursday, July 13. The principle payload, TDRS -- a
tracking and data relay satellite -- will be deployed from the
orbiter’s payload bay at about 3:53 p.m. Thursday. Discovery is
scheduled to land at KSC’s Shuttle Landing Facility at 7:51 a.m. July
21.

	No serious technical issues are being worked by the Shuttle
Mission Management Team and no problems are being reported from the
pad. Workers are in the process of activating the orbiter’s inertial
measurement units and making preparations to retract the rotating
service structure from the vehicle as early as 5:30 p.m. today. This
move could be delayed by several hours without impacting the overall
schedule if weather threatens the area this afternoon.

	Loading of the external tank with cryogenic propellants is
scheduled to begin at about 1:21 a.m. tomorrow.

	Air Force weather forecasters currently indicate a 40 percent
probability of weather prohibiting launch on Thursday. The primary
concerns are for clouds associated with showers and thunderstorms and
a chance of crosswind violations at the Shuttle Landing Facility.
During Thursday’s launch window, the winds at Pad B are expected to
be from the east at 10-15 knots; temperature 82 degrees F; visibility
7 miles; humidity 77 percent; and clouds scattered at 3,000 and
10,000 feet, and broken at 30,000 feet. The 24-hour-delay forecast
reveals similar conditions and a 40 percent chance of violation.

	Today, the five-member astronaut crew will be briefed on
tomorrow’s launch weather outlook at KSC and the TAL sites in Spain
and Africa. Also today, the crew will receive a final mission
briefing and make last minute adjustments to their flight plans while
completing their review of launch day activities.
