As Jan said, the problem is with the IUS.  A report by an investigative
committee set up by NASA after the IUS-TDRS-1 incident suggested that
the problem was with a deflated ring that cushioned the nozzle of the
IUS.  NASA is currently investigating this and, if it turns out that this
is indeed the problem, hopes to have it corrected AND TESTED by June
of next year.  Meanwhile, they are contemplating using the third stage
of a Delta rocket in replacement of the IUS for upcoming missions.
