All ISS systems continue to function nominally, except as noted previously or below. Flight Control commended the crew for doing “a good job getting organized on orbit yesterday”.

FE Alexander Kaleri performed in-flight maintenance (IFM) on the Russian segment (RS) SOGS air revitalization subsystem, replacing the Service Module (SM)’s GL2106 gas analyzer for carbon monoxide (CO) with a spare from FGB stowage. [After swapping the GL2106 units, MCC-Moscow turned off the BITS2-12 onboard telemetry system and its VD-SU control system mode to allow its reconnection to the new gas analyzer by Kaleri. Afterwards, the BITS was commanded on again, and Sasha closed out the IFM.]

Foale and Kaleri opened the Lab forward hatch, ingressed the PMA-2 (pressurized mating adapter #2) and completed transfer and stowage of U.S. equipment in it. [After preparing for the ingress, the crew gathered the equipment identified on an uplinked list for the transfer. All items listed are approved for the PMA-2 environmental conditions (vacuum) and are not required prior to the next Shuttle mission. The adapter was then pressurized and a leak check conducted before the Lab fwd hatch to it was opened. For the actual equipment relocation and stowage, three hours, beginning at ~6:45am EST, were timelined. Stowed items are being contained in the PMA within “walls” constructed with bungee cords so that they cannot migrate into the hatch operational envelopes. After completion of the equipment stowage, the forward hatch seal was inspected and cleaned, and then the hatch was closed for the subsequent PMA-2 depressurization and leak check. For the depress, which could generate a slight reaction force, ISS was moded to attitude hold at 12:15pm for 75 minutes.]

To confirm that UOP-3 (utility outlet panel #3) reconfiguration yesterday was done properly, Mike was provided with an uplinked diagram showing the desired setup of connections between UOP-3, the two Ku-band power supplies and the EarthKAM’s DCS-760 digital camera system.

Sasha Kaleri attended to the daily routine maintenance of the SM SOZh life support system (including ASU toilet facilities) and later prepared the daily IMS (inventory management system) delta file for automatic export/import to update the databases.

Both crewmembers worked out with their daily 2.5-h program of physical exercise, on TVIS treadmill, RED expander, and CEVIS (cycle ergometer with vibration isolation).

On 10/31, the crew reported failure of the VELO cycle ergometer in the SM. The device is currently inoperable, and Moscow’s IBMP (Institute for Bio-Medical Problems) is working on an in-depth troubleshooting procedure. [The failure is in the control module, which regulates the resistance (load). There is one additional control module on board, but it is failed as well. Until the VELO is repaired, other exercise devices will need to be used.]

Foale’s originally scheduled repair work on the SAMS (space acceleration measurement system), whose ICU (interim control unit) laptop did not properly boot up after it locked up on 10/24, was deferred to a later date. [Planned are partition repair on the laptop’s HDD (hard disk drive) and cleaning of the SAMS filter.]
The crewmembers again had a “free” hour each for station familiarization and acclimatization, as is standard daily rule for the first two weeks after starting station residency.

Yesterday’s inspection of the CMRS (Crew Medical Restraint System) verified that there were no cracks/protrusions on the shoulder strap clip.

The SM’s Terminal Computer (TVM) is currently running on only one lane (of three), after lane 3 was “voted” out of the set on 10/30 (1:05 pm EST). Lane 2 had previously dropped out (on 9/26). The remaining lane 1 is processing in stable configuration, and the computer is performing all required tasks. Re-integration of all three lanes is scheduled for next Thursday (11/6).

Correction: CDRA (carbon dioxide removal assembly) was yesterday erroneously reported to be operating in single-bed mode after failure/shutdown. This “slipped in” from an earlier status report (10/25). Dual bed operation has long since been regained, and the CDRA is now in ‘standby’.

Today’s CEO (crew earth observation) targets, taking into account the current LVLH attitude, and including the targets of the Lewis & Clark 200-year memorial locations, were Tigris-Euphrates, Turkey (looking left for detailed views of new dams and the associated infrastructure on the Euphrates River where it traverses the mountains of southern Turkey), Baghdad, Iraq (good pass for a synoptic view of the city left of track where the rivers flow closer together), Lake Nasser, Toshka Lakes, Egypt (nadir pass over the new Toshka Lakes in Egypt’s south. Detailed shots were requested of the new agricultural developments that have begun to sprout around the easternmost new lake), Bamako, Mali (this small capital city lies on the east side of the Niger River, and can be located at the point where linear transportation routes are focused), Marietta, Ohio (LEWIS & CLARK SITE: Marietta is noted historically as the oldest settlement on the Ohio River. It is located about ten miles upriver from Parkersburg, West Virginia, where the Muskingum River enters from the north and the Ohio makes a large meander north. In the summer of 1803, on their way to St. Louis, Lewis and Clark stopped here for a visit as it was one of the few settlements they encountered on their way west), Moundsville W VA (LEWIS & CLARK SITE: Looking left of track. This is an early science site. On Sept. 10, 1803 Lewis stopped [near present day Moundsville, West Virginia] to view “a remarkable artificial mound of earth” called the Indian Grave. It was 310 ft in circumference at the base and 30 feet in diameter at the top and being 65 ft tall. This mound had a 60 ft wide ditch around it. Near the summit grew a white oak tree 13 ®ˆ feet in girth that Lewis estimated to be 300 years old), Tropical depression, G Mexico (Dynamic event. The remnants of Hurricane Nicholas have entered the gulf, tracking fast WSW towards the Yucatan. This small well-formed storm is predicted to be left of track or under track [between the outer keys and Yucatan]. It is being watched for possible development as an unusually late tropical storm), and Patagonian Glaciers (the larger southern ice field is clearing. Smaller glaciers still need to be photographed in detail on the south end [usually the cloudiest part] and on the east [Patagonian] side).
