NASA will launch an emergency
repair mission this fall to the Hubble
Space Telescope, which is in danger
of shutting down.
NASA decided Wednesday to move
up the next regularly scheduled
Hubble visit to October so that
spacewalking astronauts can fix the
telescope's deteriorating pointing
system. The mission had been set for
June 2000.
Two of Hubble's six gyroscopes, needed for pointing and
stability, have
failed since astronauts' last service call, in 1997. And
a third gyroscope is
partly broken and is considered unreliable.
