Operations CXO Status Report

Friday 18 July 2003 7.00am EDT

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

The first Aspect Camera dark current calibration following the lowering of the CCD temperature from -10 to -15 deg C was conducted on July 14. An Initial analysis of the data indicates a reduction in the number of warm pixels by 50-60%, as expected.

During the last week the IRU-1 gyro-1 current remained near a base level of 150 mA with some noisy periods. Products and procedures are on track for the planned swap to IRU-2 scheduled for 7.30am EDT on July 19. The swap is planned during a perigee passage and is not expected to impact science operations.

The observing schedule for next week is shown below and includes an observation of Eta Carina coordinated with RXTE.

All spacecraft subsystems, with the exception of the MUPS thruster A-1 under investigation, continued to operate nominally.
