MISSION: STS-78 -- LIFE AND MICROGRAVITY SPACELAB (LMS)

VEHICLE: Columbia/OV-102
LOCATION: Pad 39B
LAUNCH DATE/TIME: June 20 at 10:49 a.m. (EDT)
LAUNCH WINDOW: 2 hours, 30 minutes
TARGET KSC LANDING DATE/TIME: July 7 at about 9:51 a.m.
MISSION DURATION: 16 days, 22 hours, 2 minutes
CREW SIZE: 7
ORBITAL ALTITUDE and INCLINATION: 173 statute miles/39 degrees

NOTE: Work in the aft main engine compartment continues with
close-outs for flight targeted for completion by Saturday. Countdown
preparations are in work at the pad and the contingency space suits
are being checked for flight. Tonight and most of tomorrow the pad
will be closed for scheduled ordnance installation and connection and
for pressurization of the hypergolic reactants system. The countdown
will begin at the T-43 hour mark at 4 a.m. Monday, June 17.

KEY STS-78 OPERATIONAL MILESTONES (dates are target only):
Check-out contingency space suits (today)
Ordnance operations and pressurization of hypergolic system (Wednesday)
Complete aft engine compartment close-outs (Saturday)
Begin countdown at the T-43 hour mark (4 a.m. June 17)
Crew arrival (3:30 p.m. June 17)


MISSION: STS-79 -- 4th MIR DOCKING & SPACEHAB DM

VEHICLE: Atlantis/OV-104
LOCATION:  Orbiter Processing Facility bay 1
TARGET LAUNCH DATE: July 31 at about 11:42 p.m. (EDT)
LAUNCH WINDOW: 7-10 minutes
TARGET KSC LANDING DATE: August 9 at about 8:17 p.m.
MISSION DURATION: 8 days, 20 hours, 35 minutes
CREW SIZE: 6
ORBITAL ALTITUDE and INCLINATION: 196-245 statute miles/51.6 degrees

NOTE: The pitch actuator on Space Shuttle main engine no. 1 will be
replaced and the work will be done in the VAB after the vehicle is
mated to the external tank. This additional work in the VAB will
prompt an earlier than planned roll out from the OPF to provide time
for the additional work in the VAB. No impact to the overall schedule
of mission STS-79 is expected.

KEY STS-79 OPERATIONAL MILESTONES (dates are target only):
Close payload bay doors for flight (June 19)
Roll Atlantis to Vehicle Assembly Building (June 21 -- change from June 24)


PREPARATIONS FOR ORBITER MAINTENANCE DOWN PERIOD

VEHICLE: Endeavour/OV-105
LOCATION: Orbiter Processing Facility bay 3

NOTE: The payload bay doors are again open and preparations underway
to deservice the hypergolic reactants system.

	Endeavour is being prepared for its first Orbiter Maintenance
Down Period (OMDP) which involves sending the orbiter to Palmdale,
CA, for about eight months of major modifications and structural
inspections. Delivery to Palmdale will occur around the first of
August. Endeavour's next mission will be the first International
Space Station assembly Space Shuttle flight, scheduled for launch
from KSC in late 1997.

KEY PRE-OMDP OPERATIONAL MILESTONES (dates are target only):
Remove Space Shuttle main engines (June 18)
Remove right hand orbital maneuvering system pod (June 26)
Remove forward reaction control system (June 29)
Remove left hand orbital maneuvering system pod (July 2)


MISSION: STS-82 -- HUBBLE SPACE TELESCOPE SERVICING MISSION - 2

VEHICLE: Discovery/OV-103
LOCATION: Palmdale, CA

NOTE: Discovery is currently in Palmdale, CA, where a series of
modifications and thorough inspections are being finalized as part of
a regularly scheduled Orbiter Maintenance Down Period (OMDP), an
operation that periodically removes all orbiters from flight
operations. The vehicle is scheduled to be delivered back to KSC
later this month, at which time it will be towed to OPF bay 3. There,
preparations will begin for its next flight, mission STS-82, the
second Hubble Space Telescope servicing mission, set for launch in
February 1997.

KEY OPERATIONAL MILESTONES (dates are target only):
Palmdale rollout (June 25)
Begin ferry flight (June 26)
Expected arrival at KSC, weather permitting (June 27 or 28)
