ACIS focal plane temperature -113.6 14:59 LOS. Status essentially unchanged. Ascending through 21003 km. ACIS focal plane temperature -115.0 NOTES/ISSUES/PROBLEMS From the 9am status meeting: 2 Supports, data recovered, on-board loads good through 42:08:00 Had 2nd load review yesterday, reran schedule to adjust times, will have load review at 1pm today. LETG retract, HETG insert sequence planned for next week has adequate DSN contact time to assure safe and successful operation, and will remain as is in the schedule. GOT used ASVT last night and will tonight to test new software at TRW/WEST for PTP data transfer. CAPs for LETG insertion and retraction next week will be reviewed on Monday. CAPs to be circulated tomorrow.
