7. 10/13/11 CXC Status Report/CUCPage 7 Mission Operations Spacecraft –Continues to operate extremely well –Nominal passages through eclipse seasons –Safe mode on 7/6/11: First safemode in ~11 years. No hardware problems. Caused by a combination of increased gravity gradient torques at the spacecraft’s lower perigee altitudes and timing of scheduled mission events in the vicinity of perigee. Full recovery to nominal operating configuration by 7/11/11 Science Instruments –Instruments are operating extremely well –Preparing to uplink ACIS software patch to enable ACIS to automatically recognize certain kinds of harmful radiation events –Aspect camera heating during safemode serendipitously annealed some warm pixels in aspect camera CCD, reducing the number of warm pixels CXC Status Report/CUC

8. 10/13/11 CXC Status Report/CUCPage 8 Mission Operations Operations Control Center –Smooth operations –Supported safemode recovery with 24/7 operations –Installed new interface servers and software to adapt to new JPL data formats and protocols for transmitting DSN data to the OCC –Upgrading OCC air conditioning system to accommodate increasing heat loads and equipment aging Mission Planning –7 load-interrupting TOOs during this period –Observing efficiency has been increasing due to orbit evolution CXC Status Report/CUC

9. 10/13/11 CXC Status Report/CUCPage 9 Mission Operations Observing Efficiency CXC Status Report/CUC Observing time has increased due to evolving orbit
