Report # 16 
Tuesday, November 26, 1996  7 a.m. CST 
 
 The Space Shuttle Columbia continues to lead the ORFEUS-SPAS
ultraviolet telescope by 20 miles as the pair of spacecraft orbit the
Earth in tandem. The Orbiting and Retrievable Far and Extreme
Ultraviolet Spectrometer is continuing its studies of the evolution of
stars, the structure of galaxies and the nature of the interstellar
medium.

  STS-80 Commander Ken Cockrell, Pilot Kent Rominger and Mission
Specialists Tammy Jernigan, Tom Jones and Story Musgrave began their
sleep shift at 5:56 a.m. after successfully retrieving the Wake Shield
Facility that night and will be awakened by Mission Control at 1:56
p.m. for their eighth day of work in orbit.

  Today's activities will focus on additional science investigations
with the Wake Shield Facility while it is attached to the shuttle's
robot arm. Jones will unberth the Wake Shield at 6:06 p.m. CST, and
return it to its resting place in the payload bay at 9:41 p.m. CST
after using its instruments to characterize the environment around the
shuttle.

  At the end of the day, the crew will begin preparation for two space
walks by depressurizing the shuttle's cabin from 14.7 pounds per
square inch to 10.2 pounds per square inch.  The first spacewalk by
Jernigan and Jones will begin Thanksgiving night.

  Columbia is in a 221 by 214 statute mile orbit, circling the globe
every 91 minutes.
