          KSC SHUTTLE STATUS REPORT - THURSDAY, NOV. 29, 1990  11 A.M.


                        STS-35 - COLUMBIA (OV 102) - PAD 39-B

               The STS-35 launch countdown began on time this morning at  1
          a.m.    at  the T-43 hour mark.  Liftoff is planned for 1:28 a.m.
          Sunday,  Dec.  2.  Columbia's  aft compartment was closed out for
          flight at 2:50 a.m. this morning.

               Launch  team members have verified flight software stored in
          the orbiter's computers and are conducting routine checks of  the
          main  engine  controllers.  Later  this afternoon,  the orbiter's
          navigation aids will be turned on and tested.

               The Broad Band X-Ray Telescope was serviced with argon  this
          morning. Argon freezing operations are underway today and will be
          complete later this afternoon. Payload closeouts are underway and
          the doors are scheduled be closed for flight at midnight tonight.

               Preparations are underway for loading liquid oxygen and liq-
          uid  hydrogen reactants into the orbiter's power reactant storage
          and distribution system  tanks.  This  activity  is  planned  for
          tomorrow morning beginning at the T-27 hour mark.

               Tanking  operations  to  load  the external tank with liquid
          oxygen and liquid hydrogen propellants are set to begin  at  5:08
          p.m. Saturday.

               The  seven  member flight crew is scheduled to arrive at KSC
          at 11:30 p.m.  tonight.  Commander  Vance  Brand  and  Pilot  Guy
          Gardner will fly in Shuttle Training Aircraft several hours after
          their arrival.

               Weather  forecasts  for launch time on Sunday indicate there
          is a 70 percent chance that conditions will be within the  launch
          commit criteria. Scattered clouds are forecast at various levels.
          Winds  are  predicted to be out of the east to northeast at 10-16
          knots.


                       STS-39 - DISCOVERY (OV 103) - OPF BAY 1

               Main engines 1, number 2026, and 2, number 2030,   have been
          installed  in  the vehicle.  Engine 3,  number 2029,  will be in-
          stalled tomorrow.  Seven of 12 seals have been  replaced  in  the
          freon cooling system.

               A  screen test of the right orbital maneuvering system (OMS)
          pod  is  continuing  this  week  at  the  Hypergolic  Maintenance
          Facility.



                       STS-37 - ATLANTIS (OV 104) - OPF BAY 2


               Tires  have been removed from the main landing gear and will
          be removed from the nose gear today.  The brakes are scheduled to
          be  removed  today.   Orbital maneuvering system a/c motor valves
          are being checked.

               Preparations  are  in  work  to  drain  lube  oil  from  the
          auxiliary power units. Routine post-flight checks and inspections
          are  continuing on the three main engines and the thermal protec-
          tion system.


                                STS-39 BOOSTERS - VAB


               STS-39 booster stacking operations  are  continuing  in  the
          VAB. The right aft center segment was transferred to the VAB late
          last night and will be lifted to the high bay tomorrow.
