Operations CXO Status Report

Friday 18 February 2011 9.00am EST

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

A real-time procedure was executed on Feb 15 to reconfigure the battery reconditioning resistors to adjust the battery trickle charge currents. An associated flight software patch was uplinked to update the EPS fault detection logic on the Reconditioning Resistor Relay configuration. These changes are in response to expected efficiency drops due to aging of the solar arrays. Additional, real-time procedures were executed on Feb 15-16 to dump OBC-A memory as a follow-up to the Reconditioning Resistor Relay configuration patch. The dump will be used to update the baseline memory image maintained on the ground.

The schedule of targets for the next week is shown below
