Endeavour/OV-105  (STS-69) Wake Shield Facility/Spartan 201-3
VAB Transfer Aisle

	Orbiter Endeavour was rolled to the Vehicle Assembly Building
this morning.  First motion from OPF Bay 1 was at 7:52 a.m.  Arrival
in the VAB transfer aisle occurred at 8:28 a.m.  Endeavour will be
mated to the external tank/solid rocket booster stack tonight.

	In the Vertical Processing Facility, the Wake Shield Facility
was installed into the payload canister on Tuesday and will be
transported to Pad 39-A late Friday night.  It will be installed into
the payload changeout room at the pad Saturday morning.  Installation
into Endeavour’s payload bay is currently scheduled for July 10.


Columbia/OV-102 (STS-73) U.S. Microgravity Laboratory-2
OPF Bay 3

	The main propulsion system leak and functional test is
underway.  Preparations are underway for installing auxiliary power
unit No. 3.  Preparations are also beginning for potable water
servicing.


Atlantis/OV-104  (STS-71)  Spacelab-MIR Laboratory Module
On-orbit

	Initial data from the three main engines showed that they
performed flawlessly.  The twin-solid rocket booster performance was
also nominal.  They  were recovered by the solid rocket booster
retrieval ships last night.  The tow to Port Canaveral began this
morning.  Arrival is anticipated at 6 a.m. on Thursday.

	The leak rate on Atlantis’ fuel cell No. 1 oxygen liquid
reactant quick disconnect has remained constant at 3/10 lb. per hour
and is not a concern.
