STS-78/OV-102/Columbia
Life and Microgravity Science Laboratory
OPF Bay 2

	Work to remove and replace a clogged water valve on the flash
evaporator system continues.  Functional testing of the external tank
door and the main propulsion system begins today and is continuing on
the orbital maneuvering system.  The auxiliary power units are being
serviced with lube oil.  Potable water servicing is beginning today.
Polishing of windows No. 3 and 4 continues.  The payload bay
continues to be prepared for the Life and Microgravity Science
Laboratory.  In the Vehicle Assembly Building, stacking of the left
solid rocket booster continues.


STS-76

       Atlantis is in the mate-demate device at NASA’s Dryden Flight
Research Facility at Edwards Air Force Base in California.  The
source of the hydraulic leak was not found with the aft inspections.
However, it is believed to be located somewhere between the hydraulic
pump and the hydraulic filter. Offloading of residual hypergolic
fuels necessary for the ferry flight has been completed but went more
slowly than anticipated.  Therefore, the orbiter will not be mated to
the 747 Shuttle Carrier Aircraft until Friday and departure from
California is now planned for local sunrise on Saturday.  A one day
ferry flight continues to be planned, weather permitting.
