    The followin is from
         On Sunday, June 4, the successful nine-year mission of the
    Compton Gamma Ray Observatory (CGRO) will end when NASA redirects
    the spacecraft into Earth's atmosphere.  Debris from the
    controlled re-entry is expected to fall in a remote area of the
    Pacific Ocean, approximately 2,500 miles southeast of Hawaii.
        NASA controllers will fire CGRO's thrusters four times to
    lower the observatory's orbit.  After each burn, mission trackers
    at Goddard Space Flight Center, Greenbelt, MD, will determine the
    observatory's exact position and, if necessary, adjust the
    descent. The engine burns will occur at:
          Re-entry Burn #1: 9:54 p.m. EDT, Tuesday, May 30
          Re-entry Burn #2: 10:41 p.m. EDT, Wednesday, May 31
          Re-entry Burn #3: 1:37 a.m. EDT Sunday, June 4
          Re-entry Burn #4: 3:05 a.m. EDT, Sunday, June 4
