Boeing Company unveiled yesterday the first of the Upper Inertial
Stage rockets to be launched from the space shuttle.  They pack
enough power to launch satellite from the cargo bay of the shuttle
into geosynchronous orbits and also to send scientific packages
to other planets.  The IUS can also be used as the second stage of
the Air Force's Titan booster.  IUS I will be used during next
January's launch of the Challenger.
