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

	Payload bay electrical checks will conclude today for the
Life and Microgravity Spacelab (LMS)  A functional test of the waste
containment system is being performed today.  Orbiter midbody avionics
system testing and associated closeouts continue.

	In the Vehicle Assembly Building, stacking of the right
forward center booster segment is underway today.  Mating of the
external tank to the solid rocket boosters is scheduled for Apr. 30.

	In the Operations and Checkout Building, LMS is installed
into the payload canister today.  LMS will be transported to the
Orbiter Processing Facility and installed into Columbia’s payload bay
on Tuesday.


STS-79/OV-104/Atlantis
MIR-4 Docking
OPF Bay 1

	The tunnel adapter is being removed today for reinstallation
into Columbia next week.  A functional test of the forward reaction
control system is scheduled for Tuesday.  Also, a test of the main
engine turbopump system is scheduled.  Work to remove the three main
engines for maintenance will begin on Friday.

	Cleaning the aft of hydraulic fluid continues. Engineering
analysis has determined that the cause of the hydraulic leak was a
slightly misaligned dynatube fitting which had been overtorqued to
permit installation.
