Ascending through 102736 km. ACIS focal plane temperature -119.5. NOTES/ISSUES/PROBLEMS From the 9am status meeting: Three supports, data quality issues with a DSS-26 pass, but all data recovered after 4 tries. Next pass on DSS-26 had no problems. On-board loads good until 16:12:30 JAN1904 products are in work. May be out tonight for load review tomorrow, BUT there is a pending TOO which could impact schedule.
