We really want our RSPIC target to be at (LON,LAT)=(-53.7,-87.4). My calculations show a longitude change of +0.51 degrees per second. So delaying the BSR time by 15 seconds (to 21:16:54 S/C time) will move the longitude to -53.7. We'll take whatever the latitude turns out to be; that is harder to control, and possibly could get better at the same time. My calculations show the slew to be about 35 deg; you have SLW = 85.58, which is a big difference. When the incidence angle is 72, it should not be necessary to slew almost 90 degrees from the Earth direction. So I'm assuming there is a bug in your calculation, or you are using a different definition. Our calculations for SMX appear to be consistent, so there should be no thermal danger. >At 24-Nov-2005 and 10-Dec-2005 are occultations before the experiment starts. >I put the pre-calibration before the occultation, the slew during, and than >start the experiment after the occultation. Please let me know if this is ok. I think we can be more efficient. According to my calculations the occultation is from about 19:37:39 to about 20:45:39 (s/c time). For periapsis at 21:30:07 (from the orbit number file), this puts the occultation between P-112.47 and P-44.47.

But I think the long break for the occultation may make the BSR Calibration before the experiment less useful. The experiment itself should be fairly quick, since we are near pericenter. I would recommend the following: (1) Reduce BSR to 40 minutes (because the specular observation is quick) (2) Reduce each SLW to 15 minutes (this is almost enough for your 85.58; my 35 is easy) (3) Reduce the first BCAL to 1 minute (we are in occultation and can't see it) Then we have (I have also included the 15 second adjustment to improve the longitude): 2397 NOP 1 MaRS SBWU -64.22 -49.22 --- 0.00 0.00 0.00 MAD S-Band Warm-up 2397 FIX 1 MaRS BCAL -49.22 -48.22 ERT 0.00 0.00 0.00 MAD BSR Calibration 2397 NOP 1 MaRS BSLW -48.22 -33.22 ERT 0.00 0.00 0.00 MAD BSR Slew 2397 FIX 1 MaRS BSR -33.22 6.78 FIX -61.23 -88.08 -13.47 MAD ResSthPolIceCap 2397 NOP 1 MaRS BSLW 6.78 21.78 ERT 0.00 0.00 0.00 MAD BSR Slew 2397 FIX 1 MaRS BCAL 21.78 51.78 ERT 0.00 0.00 0.00 MAD BSR Calibration The pre-cal can overlap with the SBWU, so it would be from -229.22 to -49.22 and the post-cal would extend 60 minutes beyond the end of the second BCAL. These translate to Begin pre-cal 17:45:15 (ERT) end post-cal 23:26:15 (ERT) We could round these off to a DSS 63 pass request of 17:45-23:25; Sophia had earlier said that 16:51-23:51 was "very possible". The 15 second adjustment for the longitude adjustment should be easy. Compression of the experiment steps is more radical; and it depends on my slew and the willingness of people like Helen Walker to reduce the nominal times for each step. If you think this is TOO radical, your series of steps will also work; it's just not as efficient. I would rather see most of both slews and a good second BCAL than to separate the first BCAL by more than an hour from the other parts of the measurement. > Date & Time (S/C) Date & Time (ERT) LON LAT INC DIS RAN SPT SLW SMX >-------------------- -------------------- ------ ------ ----- ---- ---- ----- ----- ------ >10-Dec-2005 06:43:56 10-Dec-2005 06:49:00 -48.92 -87.65 70.69 0.61 1093 10.93 93.88 -54.47 (* see below) In quickly looking at 10 December, it appears we could improve the longitude by moving the target time EARLIER by 8 seconds (to 06:43:48 S/C time). By my calculation the slew is a little larger (38 deg) the length of the occultation a few minutes less, and the time between egress and the BSR a little less. But the same (24 Nov) compressed schedule anchored to 06:43:48 SCET should work equally well. MEX already has the pass scheduled; we only need about 03:00-08:45 and something like 02:10-09:10 is available. The requests on 9 and 12 December are high altitude passes with no nearby occultations. The standard sequence should work fine. And there's no point in attempting to optimize longitude; we cover a lot of ground with our beam from apocenter. Let me know if this makes sense or is possible.

Specifically, we saw an S-band signal during this period. We had presumed that ESOC would have turned off the onboard transmitters (both S-band and X-band) after the DOY 343 DSS-63 pass (EOT at 23:00) as they are usually very conservative about power usage. Accept to say the onboard S-band transmitter was left on since the DOY 343 DOY 63 pass (or was turned on again sometime between 23:00 and 04:10), can anyone supply an explanation as to what happened? Was it planned, or did we just miss something in the DKF? Should ESOC be informed about this? - Regards, Gene From rsimpson Sun Dec 11 19:42:46 2005 Return-Path: Received: (from rsimpson@localhost) by magellan.stanford.edu (8.11.7p1+Sun/8.11.7) id jBC3gfZ14624; Sun, 11 Dec 2005 19:42:41 -0800 (PST) Date: Sun, 11 Dec 2005 19:42:41 -0800 (PST) From: Dick Simpson 650-723-3525 Message-Id: <200512120342.jBC3gfZ14624@magellan.stanford.edu> To: Daniel.S.Kahan@jpl.nasa.gov, H.J.Walker@rl.ac.uk, JValencia@jftl.jpl.nasa.gov, JVelasco@jftl.jpl.nasa.gov, John.Reynolds@esa.int, Michel.Denis@esa.int, Olivier.Reboud@esa.int, Ricardo.G.Torres@jpl.nasa.gov, Sophia.M.No@jpl.nasa.gov, art.freiley@jpl.nasa.gov, audenrie@geo.uni-koeln.de, bernd.haeusler@unibw-muenchen.de, carone@geo.uni-koeln.de, dhinson@stanford.edu, dwight.holmes@jpl.nasa.gov, fred.jansen@esa.int, gene.goltz@jpl.nasa.gov, joerg.selle@unibw-muenchen.de, john.c.klose@jpl.nasa.gov, jtwicken@stanford.edu, len.tyler@stanford.edu, mexmps@esa.int, mueller@geo.uni-koeln.de, paetzold@geo.uni-koeln.de, rene.pischel@rssd.esa.int, rsimpson, sami.asmar@jpl.nasa.gov, stanzel@geo.uni-koeln.de, stupar@geo.uni-koeln.de, thomas.w.thompson@jpl.nasa.gov, tzegers@rssd.esa.int, walter@geo.uni-koeln.de Subject: MEX BSR - Preliminary Report Content-Length: 1565 Status: RO The December Mars Express bistatic radar experiments appear to have been successful. I was present for the observations on DOY 344 when we observed the Residual South Polar Ice Cap on Mars less than 10 minutes before pericenter. The echoes were visible in all four channels and are among the strongest we have seen in real time. There was interest in the south polar results that I presented to the AGU meeting last Monday; the new data were acquired at slant ranges about 8 times closer. That translates roughly into 64 times more signal and 10 times better surface resolution. The DOY 346 observations are winding up now. According to Gene Goltz, everything appeared nominal. He said surface echoes were present in all 4 channels. These data were collected over the Viking Lander 2 site, so there are ground truth data to compare with these bistatic radar results. There was interference (apparently from Mars Global Surveyor) during both experiments. In neither case were the interfering signals present during the central part of the surface observation. But some care may be needed in handling the calibration data to ensure that they are not contaminated by the interference. Radio science operations personnel lost control over the radio science receivers during the post-experiment "minical" on DOY 344. The equipment apparently continued to operate, and we are optimistic that the data will not be affected. The cause for this anomaly is not known; investigations are continuing. There have been no problems on DOY 346.

Larry Bracamonte eventually traced this to a typo in the MEX BSR procedure (Pre-Cal Step 10, line 2 said "US14 CNF XA1A1O2" when it should have said "US14 CNF XA1A2O2". This was fixed for the BSR on day 292 and the pre-cal went as it should have. We experienced problems again during the MEX BSR on day 344 at DSS 14. It took a couple weeks to get the data from the station, but it appears we are back to the old problem - and it is again the same typo in the procedure. I'm guessing after we fixed it for day 292, the old copies of the procedure were either not corrected or not purged. Whoever put together the briefing message for day 344 used one of the old, defective sets of instructions. Could you take whatever action is necessary to make sure this doesn't happen again? If necessary, please double check that the second line in pre-cal step 10 says "US14 CNF XA1A2O2". I'll be keeping an eye on this myself. The configuration was correct by the time we started collecting surface measurements on day 344, but the calibration is more difficult because half of the X-LCP pre-cal values are no good. The problem exists only in the procedure for DSS 14; so far as I can tell, it has not propagated to the procedure for DSS 63. Thanks, Dick PS: Thanks for the great support throughout. This is a complicated experiment, and it's only through your help that we've made it work at all. It would just be nice to beat this one remaining glitch into submission so that we don't see it again. Best wishes for the holidays, and I look forward to joining with you again in 2006 for more BSR. BTW - ESA says they are going to try specular point tracking for the experiment on 2006/022; that means we'll have an hour of surface echoes rather than just a few minutes. Although Mars is getting farther away, this is a big step forward in our science capabilities.

All planning products were correctly indicating it should be off. Since this anomaly happened extremely rarely (twice in 2 years) this is not a concern but is under further analysis.

Specifically, we saw an S-band signal during this period. We had presumed that ESOC would have turned off the onboard transmitters (both S-band and X-band) after the DOY 343 DSS-63 pass (EOT at 23:00) as they are usually very conservative about power usage. Accept to say the onboard S-band transmitter was left on since the DOY 343 DOY 63 pass (or was turned on again sometime between 23:00 and 04:10), can anyone supply an explanation as to what happened? Was it planned, or did we just miss something in the DKF? Should ESOC be informed about this? - Regards, Gene
