1J/A Flight Day 7/8 (FD7/8). Underway: Week 22 of Increment 16.

Crew sleep cycle today: Sleep 6:00am -2:30pm; wake 2:30pm -6:00am tomorrow.

After wake-up yesterday at ~3:30pm, CDR Peggy Whitson completed another session with 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, as suggested on her discretionary 'job jar' task list. (To monitor the crewmember's sleep/wake patterns and light exposure, Peggy 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.)

First activity on the FD7 schedules of FE-1-16 Garrett Reisman & MS1 Bob Behnken was to work with CSA (Canadian Space Agency) ground engineers in using the SSRMS (Space Station Remote Manipulator System) to grapple the SPDM PDGF (Special Purpose Dexterous Manipulator/Power & Data Grapple Fixture) and then conduct diagnostics and 'Brake Run-in' (BRIT) tests on the newly assembled Dextre robot. (SPDM LEE (Latching End Effector) and body ('waist') roll joint diagnostics all passed, as did the BRIT joint tests on the arms except for Arm-2's WP (Wrist Pitch) joint which exceeded the expected joint travel after brake application. Subsequent analysis showed that all SPDM arm brakes are actually meeting specifications (i.e., have adequate braking torque), but that the BRIT and diagnostic tests do not provide an accurate indication of proper brake holding torque, conservatively showing a 'false fail' result. Based on this analysis, the crew was given the Go to stow the SPDM arms for EVA-3. SPDM performance during the dexterous arm maneuvers was completely nominal. SSRMS will release the SPDM PDGF shortly before EVA-3 tonight, leaving SPDM unpowered for the duration of the spacewalk.)

FE-2 Leo Eyharts worked in the JLP (JEM Experiment Logistics Module Pressurized Section) and Node-2 to install HHGRs (Hatch Handle Guide Rings) and decals on their hatches, to help prevent the hatch handles from being stowed in the wrong position. Also installed was the EVA hatch window cover to the Node-2 zenith hatch.

CDR Whitson powered down the MSG (Microgravity Science Glovebox) in the Lab and removed all InSPACE (Investigating the Structure of Paramagnetic Aggregates from Colloidal Emulsions) and InSPACE-2 hardware as well as MSG video equipment for stowage. (Peggy also stowed remaining video tapes, the last coil assembly and all vial assemblies.)

Afterwards, Whitson disconnected the MLC (MSG Laptop Computer) and configured the MSG for its transfer to the Columbus module. (The transfer of the rack from Lab to COL is scheduled for 3/23 (FD14, Sunday, ~9:00pm).)

First task for FE-1 Yuri Malenchenko after wakeup was to set up the hardware for the Russian MBI-21 PNEVMOKARD experiment and to conduct the session, his fourth (which forbids moving or talking during data recording). The experiment is controlled from the RSE-Med A31p laptop, equipped with new software, and uses the TENZOPLUS sphygmomanometer to measure arterial blood pressure. (PNEVMOKARD (Pneumocard) is an attempt to obtain new scientific information to refine the understanding about the mechanisms used by the cardiorespiratory system and the whole body organism to spaceflight conditions. By recording (on PCMCIA cards) the crewmember's electrocardiogram, impedance cardiogram, low-frequency phonocardiogram (seismocardiogram), pneumotachogram (using nose temperature sensors), and finger photoplethismogram, the experiment supports integrated studies of (1) the cardiovascular system and its adaptation mechanisms in various phases of a long-duration mission, (2) the synchronization of heart activity and breathing factors, as well as the cardiorespiratory system control processes based on the variability rate of physiological parameters, and (3) the interconnection between the cardiorespiratory system during a long-duration mission and the tolerance of orthostatic & physical activities at the beginning of readaptation for predicting possible reactions of the crewmembers organism during the their return to ground.)

Reisman & Doi worked in the JLP on continuing its activation and preparation for the arrival of the JEM (Japanese Experiment Module) 'Kibo' later this year. (Garrett & Takao rotated the module racks back to their nominal position and reconfigured JLP for the JEMRMS (JEM Robotic Manipulator System), ICS (Inter Orbit Communication System), Saibo, Ryutai and the JRSR (JEM Resupply Stowage Rack) racks. Rack translations within the JLP are scheduled during Flight 1J after the JLP is relocated to its final location on the JEM.
Background: Saibo ('living cell') is a Japanese multipurpose experiment/payload rack system on the ISS that transports, stores and supports subrack facilities such as the CB (Clean Bench) and CBEF (Cell Biology Experiment Facility) equipment by providing structural interfaces, power, data, cooling, water and other items needed to operate science experiments in microgravity. Ryutai ('fluid') is a Japanese multipurpose experiment/payload rack system to support the FPEF (Fluid Physics Experiment Facility), SCOF (Solution Crystallization Observation Facility), PCRF (Protein Crystallization Research Facility) and the IPU (Image Processing Unit) by providing structural interfaces, power, data, cooling, water and other items needed to operate science experiments in micro-G.)

The CDR upgraded the EXPRESS Rack 2 IC (Interface Controller) computer with the new software (Release 5), then readied the A31p laptop for ops by running a batch file.

Starting a new round of RS (Russian Segment) ventilation system maintenance, the FE-1 cleaned 'Group A' fan grilles in the Service Module (SM).

Malenchenko also completed the routine maintenance of the SOZh system (Environment Control & Life Support System, ECLSS) in the SM, including ASU toilet facilities systems/replaceables plus the weekly collection of the toilet flush counter (SPK-U), water supply (SVO) readings and POTOK parameters for calldown to TsUP/Moscow. (Regular daily SOZh maintenance consists of replacement of the KTO & KBO solid waste containers, replacement of an EDV-SV waste water and EDV-U urine container, replacement of the KOV EDV for the Elektron-intended water, and processing U.S. condensate water as it becomes available in a filled CWC (Contingency Water Container) from the Lab humidifier. Weekly SOZh reports (on Sundays) to TsUP/Moscow deal with number & dates of water and urine containers, counter readings of water consumption & urine collection, plus data and total operating time of the Russian POTOK-150MK (150 micron) air filter unit of the SOGS air revitalization subsystem.)

Later, Yuri conducted the periodic (currently daily) checkout/verification of IP-1 airflow sensors in the various Russian segment (RS) hatchways, including the FGB-to-Soyuz tunnel, and the FGB-to-Node passageway. (This is especially important when the ventilation/circulation system has to cope with a larger crew on board, currently ten persons, and one of the two Russian SKV air conditioners off (SKV-1).)

After completion of N2 (nitrogen) transfer from the Shuttle to ISS (~23 lbs), Reisman took down the transfer equipment. (By IMMT (ISS Mission Management Team) decision this morning, no O2 (oxygen) will be pumped over since the transferable amount (10-14 lbs before reaching the ORCA 2100 psi threshold) is too small to justify using the lifetime-limited ORCA (Oxygen Recharge Compressor Assembly). The operational cycles allowed under Flight Rule for the ORCA's diaphragm pump have already been modified by waiver from 280,000 to 373,000 cycles. A replacement ORCA will be delivered to KSC in December this year.)

Reisman, as Eyharts before him, had 60 minutes for himself for general orientation (station familiarization & acclimatization), as is standard daily rule for the first two weeks after starting station residency.

Working from the Russian 'available time' suggestions list, Yuri Malenchenko conducted the regular daily checkup on the Japanese experiment GCF-JAXA (Granada Crystallization Facility) in the Russian TBU incubator, maintained at +20 degC, including a temperature check on its ART (automatic temperature recorder).

A second task list item for the FE-1 for FD7 was the daily monitoring, picture-taking and downloading for the BIO-5 Rasteniya-2 ("Plants-2") experiment which researches growth and development of plants (peas) under spaceflight conditions in the Lada-12 greenhouse from IBMP (Institute of Bio-Medical Problems {Russian: IMBP}).

At ~10:15pm EDT last night, both crews participated in a PAO TV event via Ku- & S-band with KMOX-Radio, St. Louis, MO (Jon Grayson), WEWS-TV, Cleveland, OH (Curtis Jackson), and WBZ-TV, Boston, MA (Ken MacLeod). Topics included the Dextre robotic system assembly, upcoming EVA-3 activities, importance of the newly installed Japanese module, Reisman's arrival to and Eyharts' return from the ISS, and the astronauts' hometown connections.

Whitson and Eyharts reconfigured the DCS-760 EVA camera with 28-mm lens, leaving it on station power until the EMU prebreathe period tomorrow morning, and initiated charging of two camera batteries in the A/L BSA (Airlock Battery Stowage Assembly) for at least 3 hrs.

Despite their busy timelines, all ISS crewmembers had time scheduled yesterday (as well as tonight after wakeup) for conducting their regular physical exercise.

Before going into their sleep period this morning, the joint crew had an hour to review timeline and procedures for EVA-3.

For both crews, currently asleep, workday begins later today at 2:30pm EDT. Rick Linnehan (EV1) and Bob Behnken (EV2) are on 'Campout' (nachalo desaturatsiy = desaturation start) in the A/L CL (Crewlock), after hatch closure this morning at ~4:45am. The two spacewalkers performed PBA (Portable Breathing Apparatus) mask prebreathe for denitrogenation, while readying their tools & equipment, then depressed the CL from 14.7 to 10.2 psi for their sleep period. (For the Campout, fresh METOX (Metal Oxide) canisters were installed in the A/L for CO2 control.)

EVA-3 Preview: EVA-3 begins at ~7:23pm and lasts approximately 6.5 hrs, ending at ~2:00am. Its major objectives are: (1) Install OTP/THA (ORU Tool Platform/Tool Holder Assembly), (2) clean up SLP, (3) transfer MISSE-6 & LWAPA (Light-Weight Adaptor Plate Assembly) and install on Columbus, (4) transfer one spare SSRMS yaw joint and two DCSUs (Direct Current Switching Units) from Shuttle PLB (Payload Bay) to ESP-2 (External Stowage Platform 2), (5) install two CLPAs (Camera, Light, PTU Assemblies) on SPDM, and (6) clean up worksite & ingress.

KOB-2 TCS Pump Switchover: Yesterday, one of the four micro pumps in the SM TCS (Thermal Control Systems)'s KOB-2 loop switched over to the backup pump in the 4SPN1 replaceable pump panel. Nominal software response was to deactivate the Russian SKV-2 air conditioner and turn on the 4SPN2 pump panel. SKV-2 was then reactivated by TsUP-Moscow through ground commanding without issues. Engineers suspect that one 4SPN1 pump has failed (both pumps are still well within their expected lifetime of ~6500 hrs, viz.: N1~4864 hrs, N2~3425 hrs). At present, thermal loop KOB-2 is active with its alternate twin-pump package 4SPN2, with KOB-1 available as redundant backup. The failed pump package 4SPN1 will be investigated. There is no spare hardware onboard.

ISS Crew Sleep Shift Planning: To synchronize the ISS crew's timeline with STS-123/1J/A docking and subsequent docked activities, Peggy's, Yuri's and Leo's wake/sleep cycle is undergoing a number of shifts which started on 3/11.
