2007.11.12 - ISS On-Orbit Status 11/12/07


Underway: Week 4 of Increment 16.

Station sleep cycle: 1:00am - 4:30pm EST.

PMA-2 (Pressurized Mating Adapter 2) relocation was successfully completed. Using the SSRMS (Space Station Remote Manipulator System), CDR Whitson and FE-2 Tani unberthed the PMA-2, transferred it, and reberthed it at the Node-2 Forward dock. (Prior to the transfer ops, the Node-2 Fwd CBM (Common Berthing Mechanism) unexpectedly deactivated due to a comm dropout. Ground controllers executed troubleshooting steps to restore the CBM to function for the transfer, and the ops proceeded nominally.)

Early after breakfast, before the transfer, Whitson removed and temporarily stowed CTBs (Cargo Transfer Bags) from Node-1 stowage location to gain access to the Node-1 P1 panel until the . THC (Temperature & Humidity Control) vent configuration in Node-1 was completed later in the day and the panel was back in place. Dan Tani then restowed the CTBs in Node-1 at panel P1.

Afterwards, Dan Tani activated the CBCS (Centerline Berthing Camera System) at the Node-2 Fwd hatch, to help in PMA pre-mate aligning for reberthing.

In the FGB, FE-1 Malenchenko meanwhile disconnected and stowed power cables for the FGB SAWs (Solar Array Wings) deploy/retract drive.

While Dan started up the DOUG (Dynamic Orbital Ubiquitous Graphics) software for monitoring SSRMS maneuvering, Peggy conducted another leak check, verifying that PMA-2 internal pressure had decreased to less than 1.4 mmHg. After notifying MCC-Houston, the Go was given for unberthing.

With the PMA PDGF (Power & Data Grapple Fixture) firmly gripped by the Canadian robotarm, the Node-1 Fwd CBM was unbolted from the ground, and the PMA slowly moved over to the ISS port side by Whitson and Tani, to be successfully docked, mated and bolted at the Node-2 Fwd CBM.

During the transfer, Yuri Malenchenko was busy auditing and restocking the Russian SSVP (Docking & Internal Transfer System) accessory kits. (Support equipment in the SSVP kits includes handles, caps, screwdrivers, extenders, quick-disconnect clamps, wrenches, etc.)

After the transfer, FE-2 Tani performed safing procedures for the SSRMS.

Malenchenko worked on the SRV-K2M Condensate Water Recovery System, removing and replacing the lifetime-expired BRPK-2 Air/Liquid Condensate Separator unit with a new spare, stowing the old part for disposal.

Yuri also continued the extended leak checking of the spare BZh Liquid Unit (#056) for the Elektron O2 generator by charging the unit once again with pressurized N2 from the BPA Nitrogen Purge Unit (# by21). The last test pressurization was on 7/19 by Kotov. (During Elektron operation, the inert gas locked up in the BZh has the purpose to prevent dangerous O2/H2 mixing. A leaking BZh cannot be used.)

CDR Whitson started preparations for the relocation of the Node-2/PMA-2 "stack" on 11/14 by deactivating the interim ventilation configuration in "Harmony", disassembling the air duct and installing an IMV (Intermodular Ventilation) valve at Node-2 aft starboard.

After Dan Tani removed the deactivated CBCS and relatched the Node-2 Fwd hatch, the crew egressed from "Harmony" and isolated the Italian-built module by closing the inner hatches (after ingressing a second time to remove covers). The CBCS was then set up at the Node-1 Fwd hatch to support the upcoming "stack" transfer.

Using the vacuum cleaner and other tools, the FE-2 performed a 15-min hatch seal inspection on the Node-1 port hatch where "Harmony" is currently berthed.

Tani also completed the periodic check of active U.S. payloads, i.e., cleaning the ANITA (Analyzing Interferometer for Ambient Air) inlet plus inspecting and filter cleaning of the CGBA-5 (Commercial Generic Bioprocessing Apparatus 5) incubator payload. (The incubator is controlled from the ground with automatic video downlinked to Earth.)

Afterwards, Dan did the periodic checkout of the prime CSA-CP (Compound Specific Analyzer-Combustion Products), #1051, changing out its sensor battery.

Using the Russian AK-1M adsorber and IPD Draeger tubes, Yuri conducted the periodic sampling of cabin air for subsequent analysis on the ground. (FE-1 started out by taking air samples in the SM (Service Module) and FGB and to check for leaked-out Freon in the SM, then switched to the IPD-CO Draeger tubes sampler to check for CO (carbon monoxide) in the SM.)

Later, Dan Tani also collected air samples with a U.S. GSC (Grab Sample Container) at the center of the Lab and SM.

Malenchenko completed the routine maintenance of the SOZh system (Environment Control & Life Support System, ECLSS) in the SM, including ASU toilet facilities systems/replaceables.

The FE-1 did the daily maintenance of the IMS (Inventory Management System), updating/editing its standard "delta file", including locations, for the regular weekly automated export/import to its three databases on the ground (Houston, Moscow, Baikonur).

FE-2 Tani had another 60 minutes for general crew orientation (station familiarization & acclimatization), as is standard daily rule for the first two weeks after starting station residency.

The crewmembers completed their physical workout program (about half of which is used for setup & post-exercise personal hygiene) on the CEVIS cycle ergometer (FE-2), TVIS treadmill (FE-1/fulltime), and RED resistive exercise device (CDR).

Dan then transferred the crew's exercise data file to the MEC (Medical Equipment Computer) for downlink, as well as the daily wristband HRM (Heart Rate Monitor) data of the workouts on RED, followed by their erasure on the HRM storage medium (done six times a week).

EMU Spacesuit Troubleshooting: During a SSATA (Space Station Airlock Test Article) chamber run on the ground this past Friday, a crew member reported the smell of smoke inside the EMU (Extravehicular Mobility Unit). The run was terminated, and the crew member extracted without incident. A mishap investigation board was formed and has recommended that all life support system operations (power, O2 ops, etc.) for the on-orbit EMUs be terminated until a root cause can be determined. Thus, the on-orbit EMUs are No Go. All other ops, such as suit resizing, can be performed.
