From ISS On-Orbit Status Report for 20/12/2011.
Soyuz TMA-03M/29S Launch Preparations: At the Baikonur/Kazakhstan Cosmodrome, L-1 preparations continue for tomorrow’s launch of the Soyuz TMA-03M spacecraft (1:16:15 PM GMT; 7:16:16 PM local).
After yesterday's successful checkouts of the CUCU (COTS UHF Communication Unit) equipment and shutdown of ground systems, CDR Dan Burbank powered down the onboard CUCU hardware early in the morning. [The testing had posed a minor command line issue which was assessed by MCC-X (SpaceX Mission Control Center), resulting in troubleshooting procedures for CDR Burbank. After cycling the circuit breaker for CUCU RIO A (Remote Input/Output A), ground teams received data from this RIO and verified proper command capability with CUCU.]
Burbank supported a ground-commanded transition of the three C&C MDM (Command & Control | Multiplexer/Demultiplexer) computers for the upcoming EPIC (Enhanced Processor & Integrated Communications) software upgrade, by reconnecting all PCS (Portable Computer System) laptops immediately after the transition. [Upon a primary C&C transition (transfer of priority between computers), all laptops disconnect. The transition was to be executed in two steps: first leaving MDM #3 as Prime, #1 as Backup and #2 on Standby, then, after checking proper execution, swapping the two latter, leaving #2 as Backup and #1 on Standby. At least 2 PCS needed to be reconnected by Flight Rule, to provide redundancy for C&W (Caution & Warning), USOS Commanding, and Telemetry Insight.]
JEMRMS Ground Control Demos:
JAXA's Robotics Team (KIBOTT) has been performing two of four ground-control demonstrations of the JEMRMS (Japanese Experiment Module | Remote Manipulator System) at the Kibo JPM, one on 12/06 (Joint OCAS Maneuver), the other this morning at ~7:35 AM-11:15 AM GMT (Unloaded/Non-Proximity Maneuver in FOR OCAS). The third (Unloaded/Proximity Maneuver and Grapple/Ungrapple) is scheduled for tomorrow, the fourth at a later date during the HTV-3 mission. The first three demos serve as the technical verification for JEMRMS unloaded maneuvering by Ground Control, the fourth demo for the verification of JEMRMS loaded maneuvering. There is no crew interaction or support required for the Ground Control Demos except for a few switch throws back on 12/05 and for an off-nominal case. [OCAS = Operator Commanded Auto Sequence; FOR = Frame Of Reference.]

From ISS On-Orbit Status Report for 22/12/2011.
After the installation of the ATV PCE (Automated Transfer Vehicle | Proximity Communications Equipment; Russian: MBRL) equipment started on 12/19, Shkaplerov today tested the MBRL, AFU (Antenna Feeder Unit), and ATV Hand Controller on the PU Control Panel, with ground specialist tagup. [Yesterday’s connection tests were nominal except for the CPD-1 (Communication Processor Deformatter-1) inside the PCE Avionics Box, which failed the self-communication test with the SM TVM (Terminal Computer). The test was repeated with the same result. CPD is a 1553 coder/decoder interface between the PCE and the TVM. Ground teams are assessing the data from these tests to recommend a forward plan. The PCE testing is in preparation for the ground fueling of the ATV-3 tanks, which occurs approximately two and a half months prior to ATV-3 launch. ATV-3 is scheduled to launch on 3/9/2012. Tanking depends on functioning onboard MBRL systems.]

From ISS On-Orbit Status Report for 27/12/2011.
CDR Dan Burbank & FE-6 Don Pettit had ~30 min. set aside for a joint review of activities associated with the upcoming EPIC (Enhanced Processor & Integrated Communications) transition and X2R10 upgrade of MDM (Multiplexer/Demultiplexer) computers, followed by a 20 min. teleconference with ground specialists via phone. [Operationally this transition is more of a series of IFMs (Inflight Maintenances) than a traditional software transition. The EPIC Unit (EIOCU, also known as the processor card) in the C&C MDMs (3 of them) and GNC MDMs (2 of them) will be replaced with the EPIC version of the processor card. Six cards launched on Progress M-11M/43P were loaded with CCS R10 & GNC R9 software; four cards delivered on Soyuz TMA-03M/29S were loaded with CCSR10 and PEPR10. The new software contains the same functionality as the previous versions; it is just running on a faster, more capable processor card.]

From ISS On-Orbit Status Report for 28/12/2011.
After yesterday's reviews and teleconference for this week's EPIC (Enhanced Processor & Integrated Communications) card testing and X2R10 software transition, CDR Dan Burbank & FE-6 Don Pettit today started out on the activities, with the Lab camcorder installed to cover the scene. [The software transition work will nominally span nine days, including several days of EPIC card testing and card installations, and several "dwell" days to monitor the upgraded MDM (Multiplexer/Demultiplexer) computers. Today, on Day 1 of the X2R10 transition, Dan had about 6 hrs to upgrade the C&C-1 (Command & Control-1) MDM, while Don was setting up and testing the GNC-2 (Guidance, Navigation & Control-2) MDM's EPIC card. ]

From ISS On-Orbit Status Report for 29/12/2011.
CDR Dan Burbank & FE-6 Don Pettit continued with this week's EPIC (Enhanced Processor & Integrated Communications) card testing and X2R10 software transition after a very successful start yesterday, which "made it look easy" (Flight Control congratulating). Today's work also went very well. [Don continued with EPIC card testing (today: C&C-3, #102, and C&C-Spare, #104. Both cards passed the test with no errors. One EPIC card remains to be tested, C&C-1, #105, planned for tomorrow. Meanwhile, Dan installed an EPIC card (#106) into the C&C-2 MDM (Command & Control-2 | Multiplexer/Demultiplexer) at Lab Deck 5. Ground teams have reviewed data dumps from that MDM; all parameters look good, and we are ready for the C&C-1 EPIC MDM transition to Primary, planned for tomorrow. Since there are now both EPIC and non-EPIC C&C MDMs (with laptops equipped with the software upgrade), if an unexpected C&C transition were to occur, MCC-H will call the crew to inform them which type of PCS (Portable Computer System) laptop to connect. If no comm is available, the non-EPIC PCS should be tried first.]

From ISS On-Orbit Status Report for 30/12/2011.
After CDR Dan Burbank's EPIC (Enhanced Processor & Integrated Communications) card replacements and X2R10 software transition, which he completed successfully, FE-6 Don Pettit today tested the final card. Both crewmembers were thanked by the ground for their hard work. [EPIC transition for the C&C MDMs (Command & Control | Multiplexer/Demultiplexer) computers started at 2:45 PM GMT, with C&C-1 (EPIC) becoming Primary, C&C-2 (EPIC) Backup, C&C-3 (Non-EPIC) Standby, available as an EPIC back-out option until its transition to EPIC on 01/05/12. During the Primary transition, all PCS (Portable Computer System) laptops were disconnected. After the transition, the crew successfully reconnected the three EPIC PCS machines, leaving the non-EPIC PCSs disconnected until the last C&C and GNC (Guidance, Navigation & Control) MDMs are converted to EPIC next week.]

From ISS On-Orbit Status Report for 03/01/2012.
For CDR Dan Burbank, it was another EPIC day. The CDR upgraded the GNC-2 MDM (Guidance, Navigation & Control-2 | Multiplexer/Demultiplexer) with its new EPIC (Enhanced Processor & Integrated Communications) card. [After power-up of GNC-2 by the ground, it was to be transitioned to Primary, while GNC-1 becomes Backup (non-EPIC). The EPIC Unit (EIOCU, also known as the processor card) in the C&C (Command & Control) MDMs (3 of them) and GNC MDMs (2 of them) are being replaced in this upgrade with the EPIC version of the processor card. Six cards launched on Progress M-11M/43P were loaded with CCSR10 & GNCR9 software; four cards delivered on Soyuz TMA-03M/29S were loaded with CCSR10 and PEPR10. The new software contains the same functionality as the previous versions; it is just running on a faster, more capable processor card.]
Afterwards, Dan supported the Primary GNC MDM transition, which involved ground-commanded locking of the Port and Starboard SARJs (Solar Alpha Rotary Joints) and thruster firings, by closing the protective shutters of the Lab, Cupola & JPM (JEM Pressurized Module) windows.

Thanks for the updates Pete. I have question. While performing a DAM, how much torque is put on the station, and what are the week points ? I assume the arraays are put to some loading, and are they locked in a certain position during the DAM ?

As for specific numbers of torque, I don't know - I suppose it would depend which vehicle was used to perform the DAM (Progress, or ATV, or SM engines).
The weak points will, I assume, be the joints between modules and components. I also assume that the joints between radial modules (i.e. modules berthed on the port/starboard/zenith/nadir positions) will experience more torque than axial modules (i.e. "the stack" of the SM + FGB + Node 1 + US Lab + Node 2).
The arrays do experience some loading, which is why the SARJ is locked in place during any reboost (unsure of the exact position).

From ISS On-Orbit Status Report for 04/01/2012.
In the US Lab, CDR Dan Burbank worked on the CUCU (COTS UHF Communications Unit) equipment at location Overhead 4, updating the Dragon CCP (Crew Command Panel) software on the T61p laptop to version 3.2 and then testing the setup, supported by live video downlink.
Conjunction Update:
Flight controllers have been tracking a possible conjunction with Object 09617 (DELTA 1 debris), TCA (Time of Closest Approach): tonight at 11:53 PM GMT. The conjunction has remained stable for the past two days. Based on the computed low risk and the stability in the data, specialists see no reason to pursue DAM (Debris Avoidance Maneuver) planning for this conjunction. Monitoring will continue through TCA.
