Operations CXO Status Report
Friday 10 January 2003, 9.00am EST
During the last week Chandra completed the observing schedule as
planned.
A real-time procedure was completed on 10 Jan to perform a state of
health check of the Momentum Unloading Propulsion System (MUPS) A-1
thruster. Analysis of data from the last momentum unloading on Dec 22
indicated a lower than expected performance from the thruster
resulting in a longer than predicted unload. A state of health check
was conducted to confirm that the continued operation of A-1 was
safe. All data indicated nominal A-1 performance during the state of
health check. A calibration of all four MUPS thrusters will be
performed on 12 Jan. The observing schedule was not impacted by the
unload or state of health check.
A Chandra press release was issued on 6 January that describes the
longest X-ray look yet at the supermassive black hole at the Milky
Way's center. For details see:

The observing schedule for next week is shown below and consists of a
series of long observations of the Orion Nebular.
