yee@trident.arc.nasa.gov (Peter E. Yee) (05/07/91)

          KSC SHUTTLE STATUS REPORT - MONDAY, MAY 6, 1991 - 11 AM

                   STS-39/DoD - DISCOVERY (OV 103) - FLIGHT DAY 9

               Discovery is scheduled to land today at  approximately  2:48
          p.m. EDT at Edwards Air Force Base, Calif. on concrete runway 22.
          Discovery  will  be  towed  to  the  Mate Demate Device at Dryden
          Flight Research Facility about three and a half hours after land-
          ing.  The flight crew will depart Edwards about five to six hours
          after landing.

               KSC's turnaround team will prepare the vehicle for the ferry
          flight  back  to  Florida.  These activities typically take about
          five days.

          - Tests of the Tacan system and S-band antenna.




                    ENDEAVOUR (OV 105) - FERRY FLIGHT IN PROGRESS

               Endeavour departed Kelly Air Force Base, San Antonio,  Texas
          at  about  10:03 a.m.  EDT today and landed at Ellington Field in
          Houston, Texas an hour later.  A ceremony will be held in Houston
          for  the  new shuttle during its planned four-hour stay.  Weather
          conditions will be evaluated to determine the  next  leg  of  the
          ferry flight to Florida.

               Last Friday,  Endeavour flew from Palmdale, Calif. to  Biggs
          Army Air Field in El Paso,  Texas where the vehicle remained  for
          two  nights.    Sunday,  Endeavour flew from El Paso to Kelly Air
          Force Base, San Antonio, Texas for an overnight stay.

               Once here at KSC and demated from the 747, Endeavour will be
          towed to the Orbiter Processing Facility  where  the  tail  cone,
          ferry  flight  kit  items,  the two simulated orbital maneuvering
          system pods,  and mock forward reaction control  system  will  be
          removed. The new orbiter's initial stay in the OPF is planned for
          about  one week.  Endeavour will be towed to the Vehicle Assembly
          Building for several months of powered down work.
