KSC SHUTTLE STATUS REPORT - TUESDAY, JUNE 4, 1991 - 11  AM

 STS-40/SPACELAB LIFE SCIENCES 1 - COLUMBIA (OV 102) - PAD 39-B
                         LAUNCH - JUNE 5

WORK IN PROGRESS:
- Countdown operations on schedule for launch on Wednesday.
- Retract the rotating service structure away from the vehicle at
11 a.m.
- Closing out the Spacelab tunnel for flight.
- Loading of 10 rodents and nearly 2,500 jellyfish on  board  the
Spacelab module and in the orbiter's middeck later today.
- 20-hour, 40-minute built-in hold ends at 5:40 p.m. today, with
count resuming at the T-11 hour mark.

WORK COMPLETED:
-  Loading  liquid  oxygen and liquid hydrogen reactants on board
the orbiter to top off the storage tanks for flight.
- Calibration of the newly installed inertial measurement unit.
- Activation of the orbiter's communications system.
- Loading of 19 rodents into the Spacelab module.  Because of in-
termittent  false leak alarms in the water delivery system of one
cage compartment of the Research  Animal  Holding  Facility,  the
water delivery system was shut down.  Consequently,  only 19 rats
have been loaded in the Spacelab.  These 19 plus the 10  rats  in
the  middeck  will  give  a  total  of  29 rodents instead of the
original 30.  This decision was made so that all animals would be
assured of adequate drinking water.  This change will still allow
all of the principal investigators to meet the scientific  objec-
tives of their investigations.

WORK SCHEDULED:
- Begin chilldown  to  load  the  external  tank  with  cryogenic
propellants at 11:40 p.m. tonight.
- Flight crew awakens at 3 a.m. tomorrow.
- Crew departs Operations and Checkout Building at 4:45 a.m.
- Launch at 8 a.m. EDT Wednesday, June 5. Launch window closes at
10 a.m. EDT.

FLIGHT CREW:
     This morning, Commander Bryan O'Connor and Pilot Sid Gutier-
rez  practiced  approaches to the Shuttle Landing Facility in the
T-38 jets.  All crew members will be briefed on the status of the
vehicle,  the payload and weather conditions expected  at  launch
time.

WEATHER FORECAST:
- Probability of having acceptable weather at 8 a.m. Wednesday is
50 percent.  For the overall window, there is a 60 percent chance
of being within launch weather commit criteria.
