Mon Apr 17 12:19:38 2006 From: William Workman Subject: HST Inertial Hold safemode recovery plans The cause of the Inertial Hold safemode has been determined to be related to a command scheduling logic problem between the FGS ITS (Internal Test Source) test activity and the standard PCS termination activity which must occur at the start of earth and moon occultation events. ... We are hopeful that we will be able to recover most of these activities on the current schedule. ...
