EVENTS GMT OBSID -------------- ---- ----- AOS, 3 fids, 5 stars, NPNT, KALM 1602 791 Notes from 9 am meeting ------------------------ OPS: Passes 2 over the last day SSR dumps 2 , of which 0 failed Data loss none Load is good -> day ? CAP none MP: load review today, 2pm. All the new OTG products are in this oload. A test load with 26 checks, short maneuvers, with and without gratings, differing combinations of HRC/ACIS moves or not is being sent out to test these new products. Watch for timing issues. S/C: Will uplink the patch to back out the solar array offpoint commands. GOT: Contrary to some reports, there was NO data corruption in the past day. SOT: Radiation is low.
