From ISS On-Orbit Status Report for 29/09/2011.

In the JAXA JPM, FE-5 Satoshi Furukawa continued the activation & checkout (commissioning) of the MSPR (Multipurpose Small Payload Rack). [Satoshi first powered up MSPR components, i.e., the VRU (Video Recording Unit)/Hub, MPC (Multi Protocol Converter) & MSPR laptop and ran a virus check on the USB memory stick from SSC-15 (Station Support Computer-15), then checked out the USB communication line in MSPR.  Afterwards, the rack components were turned off.]

Conjunction Avoidance-cum-Reboost Update:
Since today's 7:02 PM GMT conjunction with Object 23335 (S/L-4 Rocket Body) remained in the Red zone early this morning, US and Russian flight controllers agreed to perform the DAM (Debris Avoidance Maneuver) discussed earlier, in the process also replacing the reboost originally planned at 10/05, since the same targeting for downstream constraints (Progress M-13M/45P phasing) had to be used as for the 10/05 maneuver.  The maneuver was conducted at 4:44 PM GMT with the SM (Service Module) KD engines for a delta-V of 2.53 m/s, 169 sec duration and 4.6 km altitude increase, and was nominal. It also took care of another upcoming conjunction, with Object 30188 (Fengyun 1C Debris), on 10/02

ACT Test:
An ACT (American Contingency Telemetry) test by MCC-Houston and TsUP-Moscow is scheduled for tonight, with commanding to and telemetry from ISS through Russian assets. On DO3 (Daily Orbit 3, 12:45 AM-1:09 AM GMT) and DO4 (2:21 AM-2:45 AM GMT), command radio link & telemetry systems will be configured for real-time command uplink & receipt of ACT via RGSs (Russian Ground Sites), assuming no S-band command capability. For the tests, US PPCP (Pre Planned Command Package) and US real-time commanding from MCC-H will be uplinked via RGS via TsUP and RGS.

Did they record the SM engines firing on camera, or do they turn the cameras away from them for plume avoidance?

After last Saturday's (10/01) review and teleconference with "PLUTO" team specialists, FE-5 Satoshi Furukawa had ~2h15m set aside for working in Node 2 to remove & replace the ISL (Integrated Station LAN) network Router. [After preparing worksite and equipment, Satoshi's activities in Node 2 involved the physical replacement of the ISL Router with the new unit, then relocating two wireless laptops (SSC-9 & SSC-11) to Node 2 and connecting them, after which ground controllers used them to configure the new ISL Router. Satoshi then disconnected the two SSC laptops for return to their nominal locations.]

Node-2 ISL Router Update:
FE-5 Satoshi Furukawa's replacement of the ISL (Integrated Station LAN) network Router in Node 2 yesterday was successful. The Router, in location Overhead 4, is connected to a large number of Ethernet cables and a power cable. To simplify the transfer of cable connections, the failed ISL Router was raised above the new ISL Router, and Satoshi did one-for one-cable swaps between the two units. Afterwards MCC-H reconfigured the Router via SSCs (Station Support Computer) laptops #9 & #11 and the ISL Interface panel. ISS LAN (Local Area Network) and CSL (Crew Support LAN) networks are back to normal onboard ISS.

CDR Mike Fossum had about 90 min reserved for installing an IMV (Inter Module Ventilation) return jumper between Node 1 (location Deck 1) and the attached PMM (Permanent Multipurpose Module) "Leonardo", intended to facilitate IMV flow when hatches are closed. FE-5 Satoshi Furukawa assisted with the actual installation of the air duct. [Steps included removing the Node 1 Deck Fwd Outboard IMV cap, equalizing & removing the Node 1 Inboard IMV cap, reinstalling Node 1 closeout panels, installing the IMV jumper/duct, and closing out the worksite.]

JAXA Marangoni Experiment:
The crew was advised of another Marangoni bridge building event tonight (11:00 PM-5:00 AM GMT), the 10th in 24 planned bridge buildings in Increment 29/30. The experiment is performed in the Kibo JPM during crew sleep (since the liquid bridge to be formed is sensitive to g-jitter), 4 days/week at most and 24 runs in total. After the liquid bridge has been formed, the ground imposes a temperature gradient on it to produce Marangoni convection. The crew, which will be informed regularly, has been asked to avoid any disturbances in this timeframe. Even disturbances in other modules can be transmitted and cause the liquid bridge in JPM to break up, resulting in science loss.

Conjunction Alert:
Flight controllers continue to monitor the conjunction with Object #30002, debris from the Chinese satellite Fengyun 1C, currently classified as of low concern due to several tracking updates. TCA (Time of Closest Approach) will be tomorrow (10/06) at 2:04 PM GMT. A DAM (Debris Avoidance Maneuver), which would have to be conducted at ~11:46 AM GMT, is considered not necessary at this time.

CDR Mike Fossum had several hours set aside to install the ARFTA (Advanced Recycle Filter Tank Assembly) at the UPA WRS (Urine Processor Assembly | Water Recovery System). [Steps included emptying the WSTA (Wastewater Storage Tank Assembly) into an EDV-U to allow for room in the WSTA for DA (Distillation Assembly) dry-out and breaking out the RFTA (Recycle Filter Tank Assembly) modification kit for the procedure. Afterwards, the RFTA mod kit was restowed.]

COL Ventilation Test:
Today, COL-CC (Columbus Orbital Laboratory-Control Center) performed a set of COL air loop tests to assess CFA-1 (Cabin Fan Assembly-1) stability and to test two three-fan configurations for ISS Decrewing. The test ran from 8:15 AM to 4:35 PM GMT. During the tests, the crew was to minimize their presence in COL to mitigate impacting the test results.

In the JAXA JPM (JEM Pressurized Module), FE-5 Satoshi Furukawa performed troubleshooting on the failed GHF (Gradient Heating Furnace) on the Kobairo Rack, opening its MP (Material Processing) front panel and taking close-up video with the G1 camcorder for ground inspection. Afterwards, Satoshi opened the GHF SCAM (Sample Cartridge Automatic exchange Mechanism) front door and took photos of the GHF cartridge for inspection. [An anomalous overcurrent event of the GHF Central Heater occurred on 04/12/11 & 04/20/11. Suspected cause of the short circuit is inadvertent contact between a lock wire and a heater flange. Troubleshooting will involve inspection of the end heater unit and cartridge, checking the lock wire position of the new Central Heater and fix it if needed, and attaching heaters and servicing GHF-MP in order to resume the GHF experiment.]

RS Oxidizer Transfer:
Russian ground controllers performed oxidizer (NTO/nitrogen tetroxide) transfer from the FGB (Functional Cargo Block) TBO1-4 oxidizer tankage to the SM (Service Module) "Zvezda" to refill "Zvezda's" BO1 ODU (Integrated Propulsion System) oxidizer tank 1.

CDR Mike Fossum & FE-5 Satoshi Furukawa joined forces to conduct the 2nd onboard tests of Robonaut (after the first tests had to be aborted on 09/01). Robonaut was put in motion for the first time on-orbit. After performing a coordinated power-up with the ground, the crew maneuvered each arm joint to determine the differences of the micro-gravity environment by setting control gains through repetitive motions. They also performed an initial vision checkout of the high-def cameras to verify they are working and in focus. The ground then commanded Robonaut to move to the stow-position while you monitor the motion. [After configuring the Node 2 camcorder to capture activities, the crewmembers assembled the Robonaut hardware on its seat track in the Lab (location Port 2), connected cables and powered on Robonaut in conjunction with ground commanding from POIC (Payload Operations Integration Center). Mike then had about ~2 hrs for powered operations, to check out two sensors (JR3 & Joint Torque), the Motion Stop button, both arms (with adjustment damping) and Robonaut vision via its left & right camera. This required activation of Robonaut's GUI (Graphic User Interface) and telnet windows. (This had run into a snag on 09/01, preventing completion of the program within the allotted "thermal clock" time of ~2.2 hrs, to limit touch temperature). Afterwards, ground controllers ran runs scripts to bring Robonaut to the Stow Pose and closed the software applications prior to disassembly. Mike & Satoshi then decabled Robonaut and restowed the disassembled hardware in an M-03 bag at its stowage location.]

That's interesting; how would that translate to image stabilization of optics on COTS (off the shelf) cameras, like the Nikons they bring up? Could they be, or would they benefit from being, adapted to improve their response without having to worry about the gravity component? Food for thought.
Remembering those who made the ultimate sacrifice for our rights & freedoms, and for those injured, visible or otherwise, in that fight.

After midday meal, after a review of procedures, CDR Mike Fossum spent several hours in the JPM (Japanese Pressurised Module), building cabling for JAXA's ICS (Inter-orbit Communication System) with the G1 video camcorder set up for monitoring. [The ICS-PM (ICS-Pressurised Module) experienced a short on 07/31, tripping the RPC-5 (Remote Power Controller-5) of the JPM PDU a1 (Power Distribution Unit a1), which feeds power to the ICS rack. Part 1 of the troubleshooting, on 08/10, determined that the ICS system itself is the source of the issue and not the rack. Subsequently, Part 2, on 08/12, was to locate the shorted circuit in the power feed path from PDU a1 to the JPM ICS Rack, using the Multimeter instrument to check continuity (measuring resistances) in order to find short circuits in the cable. ICS-PM has been shut down due to possible short circuit inside the IP-PCDU (ICS-PM Power Control & Distribution Unit) and MUX (Data Multiplexer). The new cabling is intended to eliminate the short circuit.]

After powering down PCS (Portable Computer System) laptops in the Lab & Node 2 as well as equipment attached to UOPs (Utility Outlet Panels)-2 & -7 in Lab & UOP-1 in Node 2, CDR Mike Fossum gathered the necessary gear and began Part 1 of the lengthy IFM (Inflight Maintenance) of removing & replacing the failed RPCM (Remote Power Control Module) A4A in the Lab (to be continued tomorrow). The deactivated equipment attached to UOPs -2, -7 & -1 were then powered up again, later also the PCS laptops. [A few weeks ago RPCM A4A_C in the Lab had an RPC (Remote Power Controller) failure. The RPC provides redundant power to ER-2 (ExPrESS Rack-2) which powers the Ku-Band Receiver. RPCM A4A_C is one of several RPCMs on a power bus located at the back of the DDCU-1 (DC/DC Converter Unit-1) at LAB1P3 (Lab Port 3). Accessing the RPCM required removing the CEVIS (Cycle Ergometer with Vibration Isolation System) exercise machine and rotating DDCU-1 at LAB1P3 for the duration of the activity.]
