UPDATED MIXED FLEET MANIFEST RELEASED

   NASA today released its updated Mixed Fleet Manifest reflecting 
the flight schedule for Space Shuttle/Space Station missions 
through Calendar Year 1997 and expendable launch vehicle (ELV) 
missions through Calendar Year 2001.

   Of note in the Space Shuttle/Space Station portion of the 
manifest is the inclusion of 10 Space Shuttle flights to the 
Russian Space Station MIR between 1995-1997, representing the 
first of three phases of International Space Station cooperative 
activities.  Launch of the first Shuttle SPACELAB-MIR mission, 
STS-71, is scheduled for May 1995.

   The new manifest update also includes reflight of the Tethered 
Satellite System in March 1996, the next Hubble Space Telescope 
Servicing Mission in August 1997 and the first U.S. element launch 
of the International Space Station in December 1997.

   The manifest also reflects the recently-announced Orbiter 
Maintenance Down Period decision to modify and refurbish the 
Shuttle fleet at the Rockwell Space Systems Division, Palmdale, 
Calif.

   The U.S. commercial, expendable launch vehicle fleet continues 
to provide NASA with a reliable and efficient access to space for 
a variety of payloads supporting space science missions.

   On May 16, 1994, NASA is scheduled to launch its last Scout 
rocket from Vandenberg Air Force Base, Calif.  The Scout launch, 
NASA's 118th over a 34-year period, will carry the Department of 
Defense MSTI-2 payload into polar orbit.

   The first NASA flight of the Pegasus rocket, carrying the Total 
Ozone Mapping Spectrometer, is scheduled for June 22, 1994.  The 
last NASA launch of the Atlas-E ELV will be Sept. 29, carrying the 
NOAA-J satellite.  

   The first west coast launch of a Delta-II ELV will be NASA's 
Polar mission, originally scheduled for later this year (currently 
under review), while the first west coast launch of the new Atlas 
IIAS vehicle is scheduled for June 1998, which will carry the 
EOS-AM-1 satellite.
