SUMMARY: Romap CVP block 4 test was finalized, but an extensive power consumption was found. Investigation is ongoing. Ptolemy-SD2-Civa Combined Operation was performed successfully. ESS TxRx noise measurement session ended. During the current LOS phase a repetition of Secondary Battery monitoring will be executed.

BLOCK 4 PASS 3 PERFORMANCE REPORT: Lander activities executed from MTL during LOS: Romap CVP block 4 test was finalized. Ptolemy-SD2-Civa Combined operation has been started Lander status prior to operation: Ptolemy-SD2-Civa Combined operation has been started with heating of Civa-M. Lander AOS operation was performed from 17:16 to 01:00 (UTC)

Executed operations during pass 3:

1. 18:45 (UTC) Ptolemy-SD2-Civa Combined operation continued with the next item and ended successfully.
2. 00:45 (UTC) ESS TxRx was switched-off. Lander status at end of operation: Lander is in stand-by mode. MTL is prepared to start a repetition of Secondary Battery monitoring at 03:00 (UTC), (Battery heating to 0degC, followed by a monitoring cycle).

Additional notes:

• Throughout the pass LCC requested data from DDS via ISDN lines.
• DDS performance was nominal.

SUMMARY: All activities executed via MTL during LOS between pass 1 and 2 were successfully executed. Cosac-SD2-Civa Combined Operation was performed as expected. Cruise and Extended AFT were successfully performed. Romap was started. During the actual LOS phase Romap CVP block 4 will be finalized.

BLOCK 4 PASS 2 PERFORMANCE REPORT: Lander activities executed from MTL during LOS: Ptolemy Post Launch Mode test was finalized First Secondary Battery Monitoring (with SecBatt at –34 degC) Secondary battery was heated via TCU-2 heater Second Secondary Battery Monitoring (with SecBatt at 0 degC) Lander status prior to operation: Cosac-SD2-Civa Combined operation has been started via MTL, heating of Civa-M was ongoing Lander AOS operation was performed from 17:17 to 02:33 (UTC)

Executed operations during pass 2 (all activities were performed via MTL):

1. 18:45 (UTC) Cosac-SD2-Civa Combined operation continued with the next item and ended successfully.
2. 21:15 (UTC) 28V to Landing gear electronics was disabled to keep LG off during the following AFTs (as requested by SSA).
3. 21:16 (UTC) Cruise AFT LZ-FCP-020, V2 has been executed.
4. 22:00 (UTC) Extended AFT LZ-FCP-030, V1 was performed.
5. 00:38 (UTC) Romap CVP block 4 was started (first attempt from MTL failed due to wrong setting in the fixed RSDB command, Romap was started via adapted manual command)

Lander status at end of operation: Romap is switched-on. Additional notes:

• Access from LCC to DDS was lost from 19:07 to 19:22 (UTC). Neither data requests via FTP nor Request Log view via http was possible during that period.
• The rest of the pass DDS performance was nominal.

Lander status prior to operation:

• ESS was switched-off
• Lander is in hibernation mode
• Switch-on temperature levels at ESS and Lander YEbox were given Lander operation was performed from 18:45 to 02:33 (UTC)

Executed operations during pass 1: The following activities were performed via MTL:

1. 18:45 (UTC) ESS main side and Lander are powered on via OBCP, ESS performance and LCL15A current consumption are nominal.
2. 18:52 (UTC) ESS/Lander Link Establishment was executed. Lander packets show nominal Lander performance, TCU1 is operating
3. 18:55 (UTC) Lander has been configured to apply CDMS enhanced mode and use TCU2, TCU1 is switched off.
4. 19:10 (UTC) A TC parameter upload to prepare Lander for CVP block 4 was executed Between 19:30 and 20:05 (UTC) the return time of LCC requests from DDS shows a delay, probably caused by a large amount of dumped data (from Orbiter dump as well as from Lander dump related to the TC parameter update). Investigation is ongoing. All uploads were executed successfully. The following activities were performed manually:
5. 19:47 (UTC) ESS TxRx 1 was switched-on to perform a noise measurement.
6. 20:09 (UTC) LD-CRP-001, V1 was started to verify the carousel position BRAM contents was received as expected as well as carousel movement and final position.
7. 21:23 (UTC) Cosac S/W upload was successfully executed including Cosac LFT At 23:30 again a delay in return of LCC requests from DDS was observed during a higher Lander TM rate (due to dump of CDMS pages).
8. 23:37 (UTC) The Re-run of Cosac CV-FCP-241 was executed and successfully performed
9. Cosac and SD2 BackupRam content was checked and verified, i.e. Cosac-SD2-Civa Combined Operation can be executed as scheduled.
10. 00:16 (UTC) Ptolemy S/W patch was uploaded
11. 00:48 (UTC) Ptolemy BackupRam was checked and found OK i.e. Ptolemy-SD2-Civa Combined Operation can be executed as scheduled. The following activities were performed via MTL:
12. 00:55 (UTC) Ptolemy Cruise Phase Mode CV-FCP-235 was executed
13. 02:05 (UTC) Ptolemy Post launch Mode CV-FCP-248 was started

Lander status at end of operation:

• ESS and Lander are switched-on
• ESS TxRx is switched-on for continuous noise measurements
• Lander is prepared for CVP block 4
• New S/W for Cosac and Ptolemy has been successfully uploaded and both units are prepared for combined operation
• Ptolemy Post Launch Mode test was started Additional notes:

  a) Whenever Lander dumps data, DDS performance decreases and return on LCC requests were delayed, which will affect and delay Lander operation when manually commanded
  b) Voice loop connection to SONC is very weak and needs to be improved.
