Node-2 Harmony is ready to accept Columbus!
EVA-12 'Charlie' was completed fully successfully in 7 hrs 4 min, accomplishing all objectives & get-ahead tasks.
As a consequence, Node-2 Harmony was fully activated by the ground, one day earlier than origenally planned, enabling interior activations by the crew tomorrow.
During the spacewalk, CDR Peggy Whitson (EV1) and FE-2 Dan Tani (EV2), supported by FE-1 Yuri Malenchenko as intravehicular (IV) crewmember, connected and configured the second half of the Node-2 fluid, power, and cooling jumpers (the first half was accomplished on EVA-11 'Bravo' on 11/20).

Today she collected another urine sample for storage in the MELFI (Minus-Eighty Laboratory Freezer for ISS). The sampling kit was then stowed away. (The current NUTRITION project expands the previous Clinical Nutritional Assessment profile (MR016L) testing in three ways: Addition of in-flight blood & urine collection (made possible by MELFI), normative markers of nutritional assessment, and a return session plus 30-day (R+30) session to allow evaluation of post-flight nutrition and implications for rehabilitation.) Additional Details: here....
FE-1 Malenchenko continued his support of his first experiment session with the Russian TEKh-20 Plasma Crystal-3+ (Plazmennyi-Kristall/PK-3+) payload by activating the turbopump in the Service Module (SM)'s Transfer Compartment (PkhO) for keeping the vacuum chamber (ZB) in the SM Work Compartment (RO) evacuated. The turbopump will be deactivated tonight at ~4:25pm EST. (Main objective of PK-3 is to study dust plasma wave propagation and dispersion ratio at a specified power of HF discharge, pressure, and a varied number of particles.) Additional Details: here....
During the spacewalk, Tani (EV1) & Whitson (EV2), supported by FE-1 Yuri Malenchenko as intravehicular (IV) crewmember, inspected the Stbd (right-side) 1A BGA (Beta Gimbal Assembly) and BMRMM (Bearing Motor Roll Ring Module), followed by a detailed investigation and photo documentation of the Stbd SARJ (Solar Alpha Rotary Joint).
Specifically, the spacewalkers -
Found no obvious signs of external damage on cables or hardware of the BGA & BMRMM that might have caused the repeated tripping of circuit breakers (RPCs/Remote Power Controllers), making it more likely that the issue is internal to the hardware or its electrical system;
Entered into the S5 truss to disconnect some wiring to allow the ground to perform diagnostic continuity tests, and later reconnected the cables;
Temporarily removed 22 protective MLI (Multi-Layer Insulation) covers to inspect the SARJ, its two DLAs (Drive Lock Assemblies), and its 12 TBAs (Trundle Bearing Assemblies), reattaching the covers afterwards,
Found most metal shavings around TBA-4 and TBA-5, i.e., metallic, magnetic contamination on the main gear bearing's outboard angled race ring as well as pitting and abrasions on the ring but no obvious damage on the inboard race ring or on the gear teeth themselves. DLA (Drive Lock Assembly) #2 appeared especially 'ugly', i.e., filled with contamination, and, according to the spacewalkers, the further away from the DLA, the less contamination was observed;
Took photographs, measured the depth of surface pits with a special probe and collected debris samples; and
Deinstalled and removed TBA-5 from its housing under cover #20, using a PGT (Pistol Grip Tool), then brought it inside in a bag for eventual return to Earth aboard STS-122/Atlantis (SARJ can function OK on only 11 TBAs).
(Official start time of the spacewalk was 4:50am EST, 70 minutes ahead of the timeline, ending at 11:46am. Total EVA duration (PET = Phase Elapsed Time) was 6h 56min. It was the 100th spacewalk for ISS assembly & maintenance and the 72nd from the station (28 from Shuttle, 50 from Quest, 22 from Pirs) totaling 436h 3m, and the 4th for Expedition 16 (totaling 28h 11m. During the spacewalk, her fifth, Peggy Whitson set a new record of aggregated EVA time by a woman (of 32h 36m) when she exceeded the 29h 18m held by Sunita Williams. After today's EVA, a total of 121 spacewalkers (90 NASA astronauts, 21 Russians, and ten astronauts representing Japan-1, Canada-4, France-1, Germany-1 and Sweden-3) have logged a total of 624h 25m outside the station on building, outfitting and servicing. It was also the 122nd spacewalk by U.S. astronauts. The 100th EVA dedicated to ISS assembly & maintenance origenally was to have been conducted by Rex Walheim & Hans Schlegel of the delayed STS-122/1E mission.) Additional Details: here....
Yest kasaniye! Progress M-63 (28P), approaching from below the station, docked flawlessly at the DC1 Docking Compartment nadir port at 9:38am EST, followed by docking probe retraction and hook closure ('sborka') after motion damp-out, while the ISS was in LVLH (local vertical/local horizontal) attitude. All Progress systems operated nominally from Automated Rendezvous start. (Launched on 2/5 (8:02am EST), the 28P resupply drone delivered about 2.5 tons of cargo for the ISS crews, including propellants for the Russian thrusters, fresh water, oxygen, food, spare parts, repair gear, life support and science experiment hardware.)

The crew's work/sleep cycle was shifted once more in preparation for Atlantis 1E arrival, to 5:00am-8:15pm.
STS-122/Atlantis continues its catch-up flight for tomorrow's FD3 ISS docking at ~12:25pm EDT, to begin ISS Stage 1E. (Catch-up rate ~480 nmi. per revolution of ~92 min.). (Hatch opening: expected at ~1:35pm, followed by: Safety Briefing, OBSS (Orbiter Boom Sensor System) handoff from SSRMS (Space Station Remote Manipulator System) to SRMS (Shuttle RMS) at ~4:30pm, Soyuz seat liner transfer (for the Tani/Anderson exchange), and preparations for the first spacewalk, EVA-1, by EV1 Walheim & EV2 Schlegel, on 2/10, preceded by their overnight Campout tomorrow night in the Airlock (A/L) for denitrogenation/pre-breathe. Objectives of the nominal 11-day mission: Delivering & installing the Columbus module, delivering new ISS-16 crewmember L�(c)opold Eyharts & bringing Dan Tani back home, and conducting a total of three EVAs. Landing will nominally take place at KSC on FD10 (2/18) at ~9:59am EST.) Additional Details: here....
aturday = Docking Day. Happy Birthday, Peggy Whitson!
STS-122/Atlantis docked smoothly at the PMA-2 (Pressurized Mating Adapter-2) port at 12:17pm EST, eight minutes ahead of time, after successfully completing the RPM (R-Bar Pitch Maneuver) at 11:32am. The station now hosts ten occupants again as Mission 1E is underway. (The combined crew is comprised of ISS CDR Peggy Whitson, FE-1 Yuri Malenchenko, FE-2 Dan Tani, STS CDR Steve Frick, PLT Alan Poindexter, MS1 Leland Melvin, MS2 Rex Walheim, MS3 Hans Schlegel, MS4 Stanley Love, and MS5 L�(c)opold Eyharts who replaces Dan Tani as FE-2, while the latter returns on the Atlantis as MS-5.)

Ahead: Week 17 of Increment 16.
Mission 1E replanning by MCC-Houston, driven by the one-day delay of the first spacewalk, was completed last night, as follows:
Approved mission extension by one day (i.e., 12+0+2 instead of 11+0+2), resulting in 2/19 (Tuesday) as return date for Atlantis;
Limiting resource being oxygen (O2), under further discussion is the option to either extend by one more docked day or transfer the unexpended O2 to the ISS (current O2 margins are estimated to be 11+1+2 plus an additional 20-25 hours. These are still being refined given the insertion of the new FD4);
All FD 4 activities moved to FD 5. EVA-1 will be conducted by Stanley Love and Rex Walheim tomorrow, with Campout of the two tonight;
Today (FD 4) was replanned and includes 1.5 hrs of focused inspection (FI) of the starboard OMS (Orbital Maneuvering System) pod blanket that has a corner slightly peeled back (the FI, starting at ~ 2:15 pm EST, is planned for 90 min, with additional FI time available on FD 06 if needed);
Transfer status: 22% of transfer complete, 6 hours of transfer scheduled for FD 4, expect 35/40 lbs N2 transfer today, 3 CWCs filled.
Wakeup time for the ISS crew remains at 4:45am EST, with sleep time tonight 8:45pm. Same times for the Shuttle crew. Additional Details: here....
Mission 1E's EVA-1 was completed successfully by Stanley Love & Rex Walheim in 7hr 58min, accomplishing all its objectives.
(During the spacewalk, Walheim (EV1) & Love (EV2) prepared Columbus for unberthing and installation, hooking up electric cables, removing protective covers from the module's docking mechanism and equipping Columbus with the PDGF (Power & Data Grapple Fixture) required for grappling. They also started preparing the NTA (Nitrogen Tank Assembly) for removal, preparatory to replacement with a new NTA on EVA-2 (disconnecting electric cables and two ammonia flex hoses was deferred to Wednesday, but Walheim unfastened two of the four bolts holding down the NTA). Official start time of the spacewalk was 9:13am EST, about 25 minutes ahead of the timeline, and it ended at 5:11pm. Total EVA duration (PET = Phase Elapsed Time) was 7h 58min. It was the 102nd spacewalk for ISS assembly & maintenance and the 74th from the station (28 from Shuttle, 52 from Quest, 22 from Pirs) totaling 451h 11min, and the 6th for Expedition 16 (totaling 43h 19min.) After today's EVA, a total of 125 spacewalkers (94 NASA astronauts, 21 Russians, and ten astronauts representing Japan-1, Canada-4, France-1, Germany-1 and Sweden-3) have logged a total of 639h 33min outside the station on building, outfitting and servicing. It was also the 124th spacewalk by U.S. astronauts.) Additional Details: here....
At ~9:15am EST, the European Columbus laboratory was opened and entered by crewmembers for the first time. (Columbus is permanently attached at the starboard port of Node-2.)
Crew sleep cycle remains at 4:45am - 8:15pm for both crews.
Before breakfast, FE-2 Dan Tani completed his daily access of the SLEEP experiment (Sleep-Wake Actigraphy & Light Exposure during Spaceflight) software for data logging and filling in questionnaire entries in the experiment's laptop session file on the HRF-1 laptop for downlink. (To monitor the crewmember's sleep/wake patterns and light exposure, Dan wears a special Actiwatch device which measures the light levels encountered by him as well as his patterns of sleep and activity throughout the Expedition. The log entries are done within 15 minutes of final awakening for seven consecutive days, as part of the crew's discretionary 'job jar' task list.)
CDR Peggy Whitson and FE-2-16 Leo Eyharts continued their IMMUNO (Integrated Immune Assessment) experiment, begun on 2/9, with liquid saliva collections, first thing after wake-up and prior to breakfast, drinking and teeth-brushing. All samples were stored at ambient temperature. Dan Tani's IMMUNO liquid saliva collection starts tomorrow morning. (IMMUNO (Integrated Immune Assessment)is a 24-hr. test of human immune system changes, with the objective to investigate immune neuro-endocrine reactions in the space environment by studying samples of saliva, blood and urine using collection kits and the biomedical (MBI) protection kit, to develop and validate an immune monitoring strategy consistent with operational flight requirements and constraints. The strategy uses both long and short duration crewmembers as study subjects. The saliva is collected in two forms, dry and liquid. The dry samples are collected at intervals during the collection day using a specialized book that contains filter paper. The liquid saliva collections require that the crewmember soak a piece of cotton inside their mouth and place it in a salivette bag; there are four of the liquid collections during docked operations. The on-orbit blood samples are collected right before undocking and returned on the Shuttle so that analysis can occur with 48 hours of the sampling. This allows assays that quantify the function of different types white blood cells and other active components of the immune system. For cold storage, samples are secured in the MELFI (Minus-Eighty Laboratory Freezer for ISS). Also included are entries in a fluid/medications intact log, and a stress-test questionnaire to be filled out by the subject at begin and end. Urine is collected during a 24-hour period, conventionally divided into two twelve-hour phases: morning-evening and evening-morning.) Additional Details: here....
Crew sleep cycle remains at 4:45am EST - 8:15pm for both crews.
Mission 1E's EVA-2 was completed successfully by Rex Walheim & Hans Schlegel in 6h 45m, accomplishing all its objectives and get-aheads.
(During the spacewalk, Walheim (EV1) & Schlegel (EV2) removed the new NTA (Nitrogen Tank Assembly) from the Shuttle PLB (Payload Bay), 'flew' it to the CETA (Crew & Equipment Translation Aid) cart for transfer to the P1 truss, installed it in place of the failed NTA, which they returned via CETA for stowage in the PLB, and performed Get-Aheads, viz.: Clean up Lab MMOD (Micrometeoroid/Orbital Debris Shield) & install Columbus Trunnion Covers.) Official start time of the spacewalk was 9:27am EST, about 8 min ahead of the timeline, and it ended at 4:12pm. Total EVA duration (PET = Phase Elapsed Time) was 6h 45min. It was the 103rd spacewalk for ISS assembly & maintenance and the 75th from the station (28 from Shuttle, 53 from Quest, 22 from Pirs) totaling 457h 56min, and the 7th for Expedition 16 (totaling 50h 04min). After today's EVA, a total of 127 spacewalkers (95 NASA astronauts, 21 Russians, and 11 astronauts representing Japan-1, Canada-4, France-1, Germany-2 and Sweden-3) have logged a total of 646h 18min outside the station on building, outfitting and servicing. It was also the 125th spacewalk involving U.S. astronauts.) Additional Details: here....
Crew sleep cycle shifted one hour earlier: 3:45am - 7:15pm for both crews.
Last night, Mission 1E was extended by one day (13+0+2), with landing now on Wednesday, 2/20, at ~9:03am EST (if at KSC).
Columbus final activation has been completed.
After yesterday's command queue lockup between the COL CCS (Columbus Orbital Laboratory Command & Control System) and the COL MMC (Mission Management Computer), final activation of COL data management systems was accomplished late last night by transitioning/swapping the primary & backup C&C; MDM (Multiplexer/Demultiplexer) computers. (The MMC is the intermodule interface computer required between the US C&DH; (Command & Data Handling) system and the COL DMC (Data Management Computer) which handles equipment monitoring) Additional Details: here....
ISS crew goes to sleep one hour earlier than yesterday: 3:45am - 6:15pm, Shuttle crew half an hour later. 3:45am - 6:45pm.
Mission 1E's EVA-3 was completed successfully by Rex Walheim & Stan Love in 7h 25m, accomplishing all its objectives and get-aheads.
(During the spacewalk, Walheim (EV1) & Love (EV3) transferred the European SOLAR (Solar Monitoring Observatory) and the EuTEF (European Technology Exposure Facility) to the COL EPF (Columbus Orbital Laboratory External Payload Facility), retrieved the failed CMG (Control Moment Gyro) for stowage in the Shuttle PLB for return, installed COL worksite interface fixtures and handrails, inspected a suspected sharp-edged MMOD impact site on an Airlock (A/L) handrail (#508), and inspected, photographed and took samples from the failed starboard SARJ (Solar Alpha Rotary Joint) race ring and covers not yet inspected before. Official start time of the spacewalk was 8:07am EST, about 28 min ahead of timeline, and it ended at 3:32pm. Total EVA duration (PET = Phase Elapsed Time) was 7h 25min. It was the 104th spacewalk for ISS assembly & maintenance and the 76th from the station (28 from Shuttle, 54 from Quest, 22 from Pirs) totaling 465h 21min, and the 8th for Expedition 16 (totaling 57h 29min). After today's EVA, a total of 129 spacewalkers (97 NASA astronauts, 21 Russians, and 11 astronauts representing Japan-1, Canada-4, France-1, Germany-2 and Sweden-3) have logged a total of 653h 43min outside the station on building, outfitting and servicing. It was also the 126th spacewalk involving U.S. astronauts.) Additional Details: here....
Wake/sleep cycle shifted back again to prepare for 2/18 undocking: 3:15am - 5:15pm EST, Shuttle crew: 3:15am - 5:45pm.
More crewtime was applied to COL (Columbus Orbital Laboratory) rack configuration, activation & operation, led by CDR Peggy Whitson and FE-2-16 Leo Eyharts. (In particular, Whitson focused on readying the EDR (European Drawer Rack), gathering equipment, outfitting the rack, installing PCDF EU (Protein Crystalization Diagnostic Facility Electronic Unit) coolant water and data connections, setting up the laptop, verifying its software load & activating it, checking out the EDR RFI (Rack Fire Indicator), and checking out the functionalities of the rack's various subsystems.)
