Operations CXO Status Report

Friday 31 July 2009 9.00am EDT

Operations CXO Status Report, 31 July 2009, 9.00am EDT

During the last week Chandra completed the observing schedule as planned.

A real-time procedure was executed on July 27 to obtain MUPS pressure and temperature data at a higher rate to assist in diagnosing the cause of the drop in pressure readings. The same real-time procedure was executed on July 30.

Work continued on the fault tree analysis of the MUPS tank pressure reading drop, with focus on false readings from the pressure sensor or a leak.

The schedule of targets for the next week is shown below
