RELEASE:  97-173
COUNTDOWN TEST REVEALS FUEL LEAKS ON CASSINI MISSION CENTAUR UPPER STAGE

     During the Tuesday, August 5, terminal
countdown demonstration test, Air Force and
Lockheed Martin engineers observed leakage in the
Centaur stage of the Titan IV-B rocket for the
Cassini mission to Saturn.  This test, in which the
Centaur is fully fueled, is normally conducted to
identify problems which could affect the
performance of the Titan IV.  Leakage of this
nature can occur on occasion when the Centaur is
first tanked with cryogenic propellants.  During
this test, engineers observed some liquid hydrogen
and liquid oxygen leakage in the thrust section.

     Engineering assessments are currently being
performed to determine the cause of the leakage and
what corrective action is necessary to ready the
vehicle for the Cassini launch.  Until this has
been done, what impact this might have on the
planned October 6 launch date, if any, cannot be
definitely determined.  A repeat test will be
performed to assure that there are no additional
leaks or other issues.
