Operations CXO Status Report
Friday 29 Aug 2003, 9.30am EDT
During the last week Chandra completed the observing schedule as
planned.
The Avionics and Software Validation Test Set (ASVT) arrived at the
OCC on 24 Aug and was unloaded and set-up by the West Coast team
without incident. Checkout of the system and training is proceeding on
schedule this week.
Testing is complete for a flight software patch that will modify the
threshold criteria for triggering science instrument safing under high
radiation conditions. The change is expected to significantly reduce
the number of unwanted triggers just prior to radiation belt
entry. The patch is planned for uplink on 2 Sept.
The observing schedule for next week is shown below and includes
a series of 21 calibration observations of AR Lac.
