Flight Day 4 (FD4) of STS-124/1J.

ISS crew work cycle remains unchanged: wake 6:32am EDT; sleep 10:02pm. Welcome to Expedition 17, Greg Chamitoff!

Mission 1J's EVA-1 was completed successfully by Mike Fossum & Ron Garan in 6h 48min, accomplishing all its objectives. (During the spacewalk, Fossum (EV1) & Garan (EV2) -

released an SRMS (Shuttle Remote Manipulator System) elbow camera launch lock,
supported the transfer of the OBSS (Orbiter Boom Sensor System) from ISS to Shuttle RMS (~1:45pm),
checked out MCAS RTL (Mobile Servicing System Common Attach System/Ready-to-Latch) operation (in preparation for ULF-2),
prepared Node-2 port ACBM (Active Common Berthing Mechanism) for the installation of the JPM (Japanese Pressurized Module) laboratory,
opened Node-2 the nadir hatch window cover (in preparation for ULF-2),
prepared the JPM for installation, i.e., disconnected/stowed an LTA (Launch-to-Activation) cable, removed Passive CBM contamination covers, and released the JPM forward window launch lock (~4:10pm)
inspected the 'Datum A' surface of the Starboard SARJ (Solar Alpha Rotary Joint),
performed a Stbd SARJ cleaning test using a scraper, wipes and a special grease, and
re-installed the Stbd SARJ TBA-5 (Trundle Bearing Assembly #5) ~4:42pm.
Official start time of the spacewalk was 12:22pm EDT, about 50 minutes behind the timeline (due to an issue with Fossum's 'Snoopy' comm cap), and it ended at 7:10pm. Total EVA duration (PET = Phase Elapsed Time) was 6h 48min. It was the 109th spacewalk for ISS assembly & maintenance and the 81st from the station (59 from Quest, 22 from Pirs, plus 28 from Shuttle) totaling 499h 35min, the first for Expedition 17 and the 10th so far this year. After today's EVA, a total of 139 spacewalkers (107 NASA astronauts, 21 Russians, and 11 astronauts representing Japan-1, Canada-4, France-1, Germany-2 and Sweden-3) have logged a total of 687h 57min outside the station on building, outfitting and servicing. It was the 131st spacewalk involving U.S. astronauts. Today was also the 43rd anniversary of the first US EVA, by Ed White on Gemini 4 (June 3, 1965).)

Early in the EVA-1, the Orbiter Boom Sensor System (OBSS) was relocated from its temporary location on the ISS truss to the Shuttle on Discovery's SRMS. (After Garan released stanchions & removed a protective bag, with Fossum detaching a KAU (Keep Alive Umbilical), MS4 Akihiko Hoshide and MS1 Karen Nyberg operated the SSRMS (Space Station Remote Manipulator System) to grapple and unberth the OBSS (~1:27pm), then handed it over to the SRMS (Shuttle RMS).)

Later, the 37-ft long, 14.5-ft wide JPM Kibo was successfully transferred and installed on the Node-2 'Harmony' portside dock at 7:01pm (1st stage capture 6:42pm, SSRMS wrist limped 6:43pm, 2nd stage capture 7:01pm). Aki Hoshide: 'Houston, we have a new 'Hope' on the space station!" After the installation, ISS attitude was maneuvered to the new TEA (Torque Equilibrium Attitude) which Kibo's addition has changed. (Hoshide & Nyberg operated the SSRMS to grapple, unberth, transfer and reberth the JPM at the Node-2 Port CBM (Common Berthing Mechanism) with the SSRMS in 'limp' mode. All motorized bolts have engaged to firmly hold the science laboratory at its place, and leak checks were then initiated on the vestibule between JPM and the Node-2 port. Ingress in Kibo is scheduled for tomorrow at ~ 4:47pm EDT.)

After wakeup at ~6:32am (by a recording of high school friends of Aki Hoshide singing "Hold Me With The Robot Arm"), ending the 8.5-hr sleep period before the spacewalk, the A/L CL (Airlock Crewlock) hatch was cracked at ~7:12am for a hygiene break/with mask prebreathe for Fossum & Garan, after spending the night on 10.2 psi campout. Around 8:35am, the hatch was closed again by IVs (Intravehicular Crewmembers) for EVA preparations in 10.2 psi, followed by EMU (Extravehicular Mobility Unit) purge & prebreathe. IVs Reisman & Chamitoff assisted the spacewalkers during EMU purge, EMU prebreathe and CL depressurization. EV1/EV2 egress followed after the EMUs were switched to batteries at 12:22pm.

Before breakfast, Chamitoff performed his first session with the biomed experiment INTEGRATED IMMUNE (Validating Procedures for Monitoring Crew member Immune Function), collecting wet saliva samples. (IMMUNE protocol requires the collection to occur first thing post-sleep, before eating, drinking and brushing teeth, and all samples are stored at ambient temperature. Along with NUTRITION (Nutritional Status Assessment), INTEGRATED IMMUNE samples & analyzes participant's blood, urine, and saliva before, during and after flight for changes related to functions like bone metabolism, oxidative damage and immune function 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.)

Prior to EVA start, FE-1 Oleg Kononenko verified deactivation of onboard ham radio equipment (Kenwood in SM & Ericsson in FGB) to prevent RF interference with the EMUs, as well as proper closure of the protective Lab window shutters.

At the Node-2 port hatch, MS4 Hoshide powered up the CBCS (Centerline Berthing Camera System) in preparation for today's Kibo JPM berthing. Tonight before sleep time, Aki will disassemble the CBCS again and remove it.

Pre-dock activities by FE-2 Garrett Reisman included transferring a PBA (Portable Breathing Apparatus) from its location in Node-1 into the Airlock (A/L) for EVA support.

Kononenko conducted the standard functional check of the IP-1 airflow sensors in the various RS (Russian Segment) hatchways.

With the docked Discovery adding to the station's interior spaces, Garrett checked up on air flow by taking Velocicalc measurements between Shuttle, Node 2 and the Lab.

Afterwards, the FE-1 connected the accelerometer in the Shuttle airlock to an IWIS RSU (Internal Wireless Instrumentation System/Remote Sensor Unit). (This enabled a total of 6 RSUs throughout the stack to collect data for three 1J events: today's JPM berthing, the JLP (Japanese Logistics Pressurized Module) relocation on FD7, and the dedicated Russian thruster firing on FD10. IWIS is an SDTO (Station Development Test Objective) that records structural measurements to validate math models used in loads analysis. The data will be used to reduce conservatism and might allow relaxation of operational constraints on activities such as crew exercise, vehicle dockings and reboosts that impart structural loads to ISS. The data will also provide more accurate fatigue calculations that could result in an extension of the ISS life.)

Kononenko also conducted the periodic/long-term inspection of the SM RO (Service Module Working Compartment)'s pressure hull and ring, looking for any moisture, deposits, mold, corrosion and pitting behind panels 130, 134, 135, 138, 139, 454, also underneath the TVIS treadmill (where deposit was discovered earlier) and the cold plates (where SNT and STR lines are installed). (The inspection of the hull surface, which is coated with a primer and dark-green enamel, is done using cleaning napkins to wipe the area in question if required and reporting results to the ground. The hull inspection looks for changed color and cavities; if cavities are found, they are to be measured for depth (with chewing gum) after cleaning. Digital photographs of the shell before and after the removal of deposits were to be made for documentation.)

Also during the spacewalk, Garrett Reisman performed the periodic activation & checkout on the CSA-CP (Compound Specific Analyzer-Combustion Products) instruments. (This included the current prime unit (#1044), three backup units (#1045, #1051, #1058), sampling pumps (#1021, #1019), and four new CSA-CPs delivered on STS-124 (#1028, #1029, #1030, #1031), transferred yesterday from the Orbiter. The four new units received new batteries and, were verified to be free of contamination, plus zero-calibrated for use on ISS.)

In the SM, Kononenko took the periodic readings of potentially harmful atmospheric contaminants with the CMS (Countermeasure System) component of the GANK-4M Real-Time Harmful Contaminant Gas Analyzer suite which uses preprogrammed microchips to measure H2CO (Formaldehyde, methanal), CO (Carbon Monoxide) and NH3 (Ammonia), taking one measurement per microchip. (CMS is a subsystem of the Russian SKDS Pressure Control & Atmosphere Monitoring System.)

Garrett Reisman conducted the weekly 10-min. CWC (Contingency Water Container) audit as part of on-going WDS (Water Delivery System) assessment of onboard water supplies. (Updated 'cue cards' based on the crew's water calldowns are sent up every other week. The current cue card (17-0002I) lists 31 CWCs (~1199.5 L total) for the four types of water identified on board: technical water (619.6 L, for Elektron, flushing, hygiene, including 423.2 L non-usable water because of Wautersia bacteria), potable water (534.8 L, incl. 88.7 L currently on hold), condensate water (39.3 L), waste/EMU dump and other (5.8 L). Wautersia bacteria are typical water-borne microorganisms that have been seen previously in ISS water sources. These isolates pose no threat to human health.)

CDR Volkov, with Chamitoff assisting, performed the standard leak check on Greg's new Sokol pressure suit (to be used in case of TMA-12 contingency return, then set it up in the Soyuz BO (Orbital Module) for airing out, i.e., drying out any humidity. Kononenko later repeated the process on the Sokol gloves and stowed them with the suit in the BO.

After the spacewalkers' return on board at 7:10pm, post-EVA activities by CDR Volkov and FE-2-17 Chamitoff in the A/L will consist of --

Recharging the EMU/spacesuits with water from PWR (Payload Water Reservoir), then
Reconnecting the LTAs (Lower Torso Assemblies) to the EMUs and
Capping the UIA (Umbilical Interface Assembly (no METOX regeneration required),
Preparing the CVIU (Common Video Interface Unit) in Node-2, and
Taking photographs of the EMU gloves for downlink and inspection.
Other post-EVA activities by crewmembers include -

Returning the PBA unit from the A/L to its original stowage location in Node-1 (FE-2),
Downlinking EVA photography (FE-2),
Manual closure of the nitrogen (N2) supply valve at the A/L in preparation for the N2 line depress during FD5 activities (FE-2-17), and
Disconnecting the IWIS RSU cable to the Shuttle airlock (FE-1).
In the SM, Sergey Volkov completed the routine maintenance of the SOZh/ECLSS system, including ASU toilet facilities systems/replaceables. Removal & replacement of the failed separator pump is on tomorrow's schedule for Kononenko at ~9:30-11:30am EDT. (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, and processing U.S. condensate water as it becomes available in a filled CWC from the Lab humidifier.)

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

The ISS crew completed their physical workout program (about half of which is used for setup & post-exercise personal hygiene) on the CEVIS cycle ergometer (CDR), TVIS treadmill (FE-1, FE-2), RED resistive exercise device (CDR, FE-1, FE-2), and VELO bike with bungee cord load trainer (CDR, FE-1). (For load reasons, no exercise is allowed on ISS or Shuttle while both robotarms are grappled.)

Later, Oleg copied 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).

Greg Chamitoff had ~2.5 hrs for himself for general orientation (station familiarization & acclimatization) as is standard daily rule for fresh crewmembers for the first two weeks after starting station residency.

At ~8:00pm, Greg is scheduled for his first regular PMC (Private Medical Conference) via S- & Ku-band audio/video.

No CEO (Crew Earth Observation) photo targets uplinked for today.
