Also, two CAPs: fidlite patch check, and reset thruster counter to be done at 1 pm pass. REAL TIME OBSERVATIONS GMT OBSID ---------------------- ---- ----- (none) Notes from 9 am meeting ------------------------ OPS: Passes 3 SSR dumps 4 Data loss none Load is good -> 339:05:38 CAPs none next passes 1800,0300 MP: load review today at 1 pm S/C: We are planning CAPs first to verify that the ACA fidlite patch is still loaded, and second to re-initialize the thruster's accumulated on-time, to fix an overflow problem in the data. These may get done today. There is some trouble with GRETA making a merge file. GOT: - SOT: Radiation is low. From Pat Beyer, JPL Telecommunications and Mission Systems Manager, Chandra, Galileo, SIRTF, and STRV: "The period of high contention on the DSN is November 2003 through February 2004. I.e. it is 4 months only. And that is the period where Chandra is being asked to consider the 26M as primary support. I would hope that some 34M antenna time would be available, but that becomes a scheduling (conflict resolution) problem as we actually get to that time frame. Also, as JPL builds its case, we are trying to build more antennas to alleviate the problem...We know we cannot build enough antennas to totally erase the problem due to the high cost and short schedule." ASCDS: one QL. Meetings: CAP review at 10, OTG software review at 1:00 tomorrow.
