NASA DELAYS SHIPMENT OF X-RAY TELESCOPE
TO KENNEDY SPACE CENTER TO ALLOW ADDITIONAL TESTING
NASA announced today it will delay shipment of the Advanced
X-ray Astrophysics Facility (AXAF) from the prime contractor, TRW
Space and Electronics Group, Redondo Beach, CA, to Kennedy Space
Center, FL. The postponement, made following a review by NASA and
TRW, will allow additional time for TRW to complete testing of the
observatory and to replace an electrical switching box. AXAF had
been scheduled for shipment later this month to meet a Jan. 21,
1999, launch date.
NASA also has directed a review of AXAF, by NASA Chief
Engineer Dr. Daniel Mulville to be completed by mid-January 1999.
A new shipment date and a new launch date will be confirmed after
the review.
"We think it's prudent to wait to see what the review will
tell us before we set shipment and launch dates, so we don't
expect to ship AXAF before that. It was a difficult decision, but
we evaluated a number of options for handling the remaining work,
and selected the one that will give us the most assurance of
successfully completing the work," said Kenneth Ledbetter,
Director of the Mission and Payload Division of the Office of
Space Science, NASA Headquarters.
The remaining testing includes trouble-shooting and de-
bugging some elements of the ground test and flight software. In
addition, testing will be done to verify changes made to the
flight software.
"Our priority remains the safe and successful launch of a
world-class observatory, which has been thoroughly tested and
meets all requirements," said Fred Wojtalik, NASA Marshall Space
Flight Center Observatory Projects Office manager in Huntsville,
AL. Marshall manages development of the observatory for the
Office of Space Science.
Once in orbit, the Advanced X-ray Astrophysics Facility
will allow scientists from around the world to obtain
unprecedented X-ray images of a variety of high-energy objects to
help understand the structure and evolution of the universe. The
observatory will not only help to probe these mysteries, but also
will serve as a unique tool to study detailed physics in a
laboratory that cannot be replicated here on Earth -- the universe
itself.
