             Testing of the Orbiter Columbia continues in the orbiter
        processing facility.  The frequency response test involving the
        orbiter's hydraulically activated control surfaces and valve systems
        began Thursday morning and was essentially complete by midnight.
        Some hydraulic tests continue.  The orbiter has been lowered onto
        jacks and tests are underway on the brakes.  The necessary alignment
        of the air data probe was completed overnight.  The payload bay doors
        are scheduled to be opened today at about noon to resume work in the
        payload bay.  The helium signature leak checks of the main engines
        and main propulsion system have been rescheduled for next week after
        completion of the Crew Equipment Interface Test.

             Preparations continue for astronaut participation in the Crew
        Equipment Interface Test.  The STS-28 crew will arrive at KSC on
        Saturday afternoon and the test will be conducted on Sunday.  The
        astronauts will actively familiarize themselves with the panels,
        switches, and other items installed on the flight deck and in the
        crew cabin for the STS-28 mission.  The astronauts are expected to
        return to Houston after the test is over on Sunday night.

             Meanwhile, other scheduled powered-up testing and routine tile
        work continues on the oribter today, as well as maintenance on the
        auxiliary power units, and the KuBand TDRS antenna.

             In the Vehicle Assembly Building, instrumentation checks of the
        solid rockbet boosters are being performed.  Preparations are
        underway for relocating the stack from VAB high bay 1 to adjacent
        high bay 3.  The crawler transporter will be positioned under the
        stack today.  The move is scheduled for early Tuesday morning.
