KENNEDY SPACE CENTER SPACE SHUTTLE STATUS REPORT
WEDNESDAY, JUNE 21, 1995 (11:46 AM EDT)

LAUNCH MINUS 2 DAYS

MISSION: STS-71 -- 1st MIR DOCKING

VEHICLE: Atlantis/OV-104
LOCATION: Launch Pad 39-A
TARGET LAUNCH DATE: June 23
APPROX. LAUNCH TIME: 5:08.46 p.m. EDT
LAUNCH WINDOW: 7 minutes
TARGET KSC LANDING DATE/TIME: July 4 at 12:04 p.m.
MISSION DURATION: 10 days, 18 hours, 56 minutes
CREW SIZE: 7 up, 8 down
ORBITAL ALTITUDE and INCLINATION: 196-245 statute miles/51.60 degrees

NOTE: The countdown for mission STS-71 and the launch of Atlantis on
Friday continues today. The countdown began yesterday at 9:30 a.m. at
the T-43 hour mark. Late yesterday, engineers monitoring the pressure
of a reaction control system helium tank in the right-hand orbital
maneuvering system pod, noticed a decay in pressure of about a half
psi per hour. A leak check revealed the most probable source to be a
fitting on the fuel supply helium tank serving the right-hand
reaction control system. After the pad reopens, following the loading
of the onboard cryogenic tanks later this afternoon, that fitting
will be inspected and additional leak checks made.
	At this time, the pad has been cleared for loading the
onboard cryogenic tanks with the liquid hydrogen and liquid oxygen
reactants. Reactant loading is expected to be finished at about 2
p.m. The reactants will provide electricity for the orbiter and crew
while in space and drinking water as a by-product during their 11-day
mission.
	After the cryogenics are loaded, the orbiter’s mid-body
umbilical unit will be demated and retracted into the fixed service
structure. Final vehicle and facility close-outs will also resume.
	Tomorrow, preparations will be made to retract the rotating
service structure to launch position at about 8:30 p.m. Loading of
the external tank with cryogenic propellants is scheduled to begin at
about 7:45 a.m. Friday.
	Air Force weather forecasters are currently indicating a 70
percent probability of weather prohibiting launch on Friday. The
primary concerns are for showers and thunderstorms. During Friday’s
launch window, the winds at Pad A are expected to be from the
east-southeast at 12-16 knots; temperature 80 degrees F; visibility 7
miles; and clouds scattered at 3,500 and 7,000 feet, and broken at
25,000 feet. The 24-hour-delay forecast reveals similar conditions
and a 70 percent chance of violation.
	The seven-member astronaut crew arrived at KSC’s Shuttle
Landing Facility at 4:30 p.m. Tuesday. Today they will be involved
with checking out their mission plans and fit checks of their
equipment.
