No TLM contact during this shift EVENTS DONE OBSID -------------- ---- ----- 9 AM meeting report ------------------- Ops: 3 supports, 4 dumps, cleared 2 loads, replaced with TOO, 3 loads. Good to day 021:23:00. Mission Planning: TOO 1st maneuver 7 pm tonight. Ken Gage expects to have products out for next load by noon, review late afternoon. PCAD: plan to uplink continuous dither patch next week, 2nd radiation pass. GOT: We have not yet received the following data: Day lost time onboard time last good next good ~hrs VCDU VCDU --- ------ ------------ --------- --------- 17 3 20:58 - 23:56 4403903 4445592 18 9 06:06 - 15:26 4532201 4663338 The data from day 17, which we know were received by the ground station, are likely to arrive at OCC shortly, according to Ken Kohls. The data from day 18, which are required to be at OCC within 24 hrs, are now awaited for 23 hrs. The GOT mentioned this to JPL, who said they will begin tracing the data. In ~2 hrs the GOT will make an official inquiry. We believe the data from day 18 were received at the ground station. In summary, we do not yet have any word that these data are irretrievably lost. SOT: I reported the need for an end-to-end investigation of the mission planning process. This is already under way by RJB. This will allow us to track and reduce errors due to not allowing enough time for each stage in the procedures. There will be a telecon on the IRU tomorrow at noon EST. Evaluation of QL data done at 019:15:40 -------------------------------------------- The following observations from the last ten days should be available for review. If there is no comment after the entry, it means the image has not yet appeared in the book.
