Draft Payload Activity Schedule:

1.  PDS Go To Normal (from Eng Only Mode - EOM) and S&E_1 RTM
        - minimum 45 minutes prior to MOC power ON  (NLT DOY-065 15:09 UTC)
        - Payload Eng. concurs w/not performing PDS memory readout; Go to Normal involves a limited self-diagnostic.  PDS eng. telem should be sufficient to indicate any significant problems (i.e. any PDS "error" packets).

2.  MOC
        - Power ON (per recovery procedure) around DOY-65 19:50 UTC
        - Uplink MOC nipc(s) [TBS]
        - Final MOC state is Instr=ON, Replacement Htr=OFF, Focus Htrs set

3.  MAG/ER
        - Adjust uplink file per Monte Kaelberer e-mail msg. to Steve Odiorne dtd 05 Mar 2002 14:44:07 -0500, subj: "MGS MAG-ER Turn-on"
        - Power ON MAG/ER (per recovery procedure w/modified file) during S&E_1 windows (DOY-65 19:50-21:02 and 21:48-23:00 SCET)
        - Final state is Instr. ON, ER Htr=ENABLE, Patch loaded
        - Patch enable won't be sent during C-mode recovery; it will be sent a day or two later as a MAG/ER Team (true) NIPC

4.  MOLA
        - Power ON and PATCH to be accomplished in mm159 sequence
        - Executes around DOY-067 10:00-10:30 (SCET?)
        - Per Peggy Jester email dtd 5 Mar 2002 14:10:04 -0500, subj: "MOLA turn-on"
        - Final state is Instr. ON, Arm State=ARM, Enable State=ENABLE, Replacement Htr=ON, Radiometer Mode Patch loaded

5.  TES
        - Via real-time commanding:
                -- Load-n-go TES Power ON, DOY-067 21:05 - 21:20 (UTC)
                -- TES nipc#1           , DOY-067 21:30 - 22:15  "
                -- TES nipc#2           , DOY-067 22:55 - 23:15  "
        - TES "GO" required for Power ON and nipc#1
        - nipc#1 is not to be sent prior to "Power ON load-n-go" rad. plus ~10 min.
        - Final state is Instr=ON, Replacement Htr=ON, ALAGOR patch and tables loaded (via nipc#1) and orbit# set (via nipc#2)

6.  MR
        - Set MR Transmitter State to "Enable", ref. Telem Ch# I-0005, per C-Mode recovery procedure
        - This command can be sent at ACE convenience on any day 065 thru 067

I am not sure about the exact timing of the contingency mode. Perhaps Dick has access to more accurate numbers. I believe that our last good occultation recording on 02/27 ended at 20:41 ERT, and our first good recording on 03/07 started at 03:11 ERT. One earlier occultation was recorded on 03/07 but the (egress) occultation was not captured. If you could fill in this gap, that would be great. Thanks again...

One earlier >occultation was recorded on 03/07 but the (egress) occultation was not >captured. Joe is correct. The occultation ending at 2002-02-27T20:41:00 was an ingress. The SNR was down by about 3 dB, but not necessarily something to worry about. 30 minutes later, on egress, the spacecraft had entered C-mode. There was very little signal for the next several hours. It appears the normal carrier link was re-established on 2002-03-05 at about 23:00. Occultations (and probably other normal science operations) resumed shortly after midnight on 2002-03-07. Our first occultation recording began at 01:53; but, as Joe notes, we may have missed the egress itself for other reasons. I'm guessing there is good tracking data up to 2002-02-27T20:41:00 (give or take a few minutes for the occultation). And there MAY be tracking data as early as 2002-03-05T23:00:00; but we don't need orbits until at least 2002-03-07T01:53:00. All times are Earth Receive Time (UTC).
