(Garrett collected three 450 mL samples (for postflight microbial analysis) and two 750 mL samples (for postflight chemical analysis) from each of three ports (SRV-K hot, SRV-K warm, SVO-ZV) for return on STS-124/1J. The small amounts of water used for flushing the equipment were later reclaimed from the flush bag.)
CDR Volkov serviced the Russian BMP (Harmful Impurities Removal System), starting the "bake-out" cycle to vacuum on absorbent bed #2 of the regenerable dual-channel filtration system. The regen process will be terminated tonight at ~5:15pm EDT. Filter bed #1 was regenerated yesterday. (Regeneration of each of the two cartridges takes about 12 hours and is conducted only during crew awake periods.)
FE-1 Kononenko completed the troubleshooting of RS (Russian Segment) condensate processing, begun yesterday, removing the line-2 BRPK Condensate Separation & Pumping Unit of the SRVK-2M Multifiltration Kit, then installing it on line-1 to replace the failed BRPK-1 separator. The latter was discarded as trash and logged in the IMS (Inventory Management System). The BRPK is now processing US condensate.
Volkov performed maintenance on the #1 loop (KOB-1) of the Russian Thermal Control System (SOTR) in the Service Module (SM), using a manual pump, hose adapters and a pressure gauge (VK-316M). (Purpose: to determine the volume of free air in KOB-1 and check the leak tightness of the KOB-1 accumulator bellows; also: to perform preventive maintenance on the SOTR loops' solenoid valves.)
Later, Sergey transferred US condensate, collected from the US CCAA (Common Cabin Air Assembly) air conditioner in a CWC (Contingency Water Container), to a Russian EDV container for processing as technical water for the Elektron oxygen (O2) generator.
Kononenko meanwhile continued the current round of the monthly preventive maintenance of RS ventilation systems in the Funktsionalnyi-Grusovoi Blok (FGB), cleaning the grilles of its interior panels, the mesh screen of its central ventilation fan TsV1, and the detachable fan screens 1, 2, and 3 of the three SOTR gas-liquid heat exchangers (GZhT4) and the fixed grill of GZhT #4.
In the Lab, the FE-2 serviced the EMCS (European Modular Cultivation System). (The periodic maintenance was performed in three steps: (1) replacing the water reservoir of Rotor A (#FM001) with a fresh reservoir (#FM005), replacing the RBLSS (Rotor Based Life Support System) module #FM008 on Rotor B with #FM004, closing the EMCS main door and verifying that all EMCS and EXPRESS locker switches are in the On position.)
In the SM, Sergey completed the routine maintenance of the SOZh/ECLSS system, including ASU toilet facilities systems/replaceables. (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.)
Oleg performed the daily IMS 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).
Garrett filled out the regular FFQ (Food Frequency Questionnaire), his tenth, on the MEC (Medical Equipment Computer). (On the FFQs, NASA astronauts keep a personalized log of their nutritional intake over time on special MEC software. Recorded are the amounts consumed during the past week of such food items as beverages, cereals, grains, eggs, breads, snacks, sweets, fruit, beans, soup, vegetables, dairy, fish, meat, chicken, sauces & spreads, and vitamins. The FFQ is performed once a week to estimate nutrient intake from the previous week and to give recommendations to ground specialists that help maintain optimal crew health. Weekly estimation has been verified to be reliable enough that nutrients do not need to be tracked daily.)
In preparation for the EVA (Extravehicular Activities) prebreathe periods next week, Reisman completed the periodic calibration of two CSA-O2 (Compound Specific Analyzer-Oxygen sensor) instruments (#1041 & #1052), using a calibration tank with accurately known pressure (2100 psi).
Later, Reisman used the hand-held CDMK (Carbon Dioxide Monitoring Kit, #1002) to collect measurements for the regular atmospheric status check for ppCO2 (Partial Pressure Carbon Dioxide) in the Lab, SM (at panel 449) and COL (Columbus Orbital Laboratory), and recording CO2 readings and battery 'ticks'. (Batteries were to be replaced if necessary. After all readings were taken, the CDM was deactivated and returned to its stowage place at LAB1S2.)
The crew conducted their regular 2.5-hr. physical workout program (about half of which is used for setup & post-exercise personal hygiene) on the CEVIS cycle ergometer (CDR, FE-2), TVIS treadmill (CDR, FE-1), RED resistive exercise device (CDR, FE-1, FE-2) and VELO bike with bungee cord load trainer (FE-1).
Afterwards, Reisman 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).
From their discretionary task suggestion list, CDR Volkov & FE-1 Kononenko were to perform more Progress 29P unloading & cargo transfers 'as time permits', logging movements in the IMS.
Garrett Reisman had another hour set aside for more personal departure preparations.
Yesterday, the FE-2 replaced the failed LHA (Lamp Housing Assembly) in the US Airlock, using the last LHA spare on board.
At ~4:20am EDT, the crew held the regular (nominally weekly) tagup with the Russian Flight Control Team (GOGU; (Glavnaya operativnaya gruppa upravleniya = 'Main Operative Control Group')), including Shift Flight Director (SRP), at TsUP via S-band/audio, phone-patched from Houston and Moscow.
At ~4:35am, Sergey & Oleg linked up with TsUP-Moscow stowage specialists via S-band to conduct the weekly IMS tagup, discussing stowage issues and equipment locations. (Topics of the exchange included necessary ASU toilet repair/transfer updates in the IMS, recommended stowage locations for ASU components, confirmation of the new Sokol spacesuit's serial number, bagging & pre-packing of the zipper-damaged Sokol for return on the 1J Shuttle, etc.)
At ~11:00am, Garrett Reisman held a CDE (Crew Discretionary Event) via S-band/audio & Ku-band/video.
At ~3:00pm, the ISS crew is scheduled for their regular weekly tagup with the Lead Flight Director at JSC/MCC-H via S-band/audio. (S/G-2 (Space-to-Ground 2) phone patch via SSC (Station Support Computer)).
WDS Update: An updated Water Delivery System 'cue card' was uplinked for the crew's reference. (The new card (17-0002G) lists 35 CWCs (~1257.3 L total) for the four types of water identified on board: technical water (650.7 L, for Elektron, flushing, hygiene), potable water (534.8 L), condensate water (66 L), waste/EMU dump and other (5.8 L). Of the 35 containers, 12 CWCs with technical water (454.3 L) can only be used for flushing due to Wautersia bacteria contamination, and 2 CWCs with potable water (88.7 L) are also not cleared for use except for flushing.)
STS-124/1J Launch: Preparations are progressing smoothly at KSC for tomorrow's launch of Discovery on Mission STS-124/1J. Weather outlook is 'promising' for launch, with an 80 pct. chance of being favorable at launch time. 1J carries the largest payload so far to the ISS and is the second of three missions with components to complete the JAXA (Japan Aerospace Exploration Agency) JEM laboratory 'Kibo' (Hope). Some highlights are:
Crewed by CDR Mark Kelly (IV-suited), PLT Ken Ham (IV-tasks, Rob1/2), MS1 Karen Nyberg (Rob1), MS2 Ron Garan (EV2, Rob1/2), MS3 Mike Fossum (EV1, Rob1/2), MS4 Akihiko Hoshide (J1, JEM), & MS5 Greg Chamitoff (Exp 17);
Starting 6/2 (FD2), wake/sleep cycle for the ISS crew will be shifted from 2:00am EDT to 6:32am. Since the early undock time on FD12 (7:33am) drives crew wakeup 2.5 hrs earlier, crew sleep will be shifted 30 min earlier each night starting FD7;
JPM (Japanese Experiment Module Pressurized Module) will be installed at Node-2 on port on FD4, followed by an overnight leak check. JPM is launched with four racks (ECLSS/TCS-1, ECLSS/TCS-2, EPS-2, DMS-2) already installed; the remaining racks are already on orbit in the JLP (JEM Logistics Module);
JLP will be transferred to the JPM zenith on FD7;
Three EVAs (see below), with Reisman & Chamitoff in the A/L supporting EVA-1 campout;
Reisman & Chamitoff's 'generic' face-to-face handover time will be 16 hrs max;
ISS will provide power to the Discovery via the SSPTS (Station-Shuttle Power Transfer System) from post-docking to just before undocking;
Focused inspection of the Orbiter will be on FD7.
CEO (Crew Earth Observation) photo targets uplinked for today were Typhoon Nakri, Pacific Ocean (Dynamic Event. Looking to the right and ahead of track as ISS passed over the Philippines for this compact and powerful typhoon. Investigators suggested beginning the photography session using a 50 mm lens during approach to capture the entire storm system, then switching to the 800 mm for detailed images of the typhoon eye as ISS drew close to the storm), South Tibesti Megafans, Africa (the crew had a nadir pass through the center of this site. Looking for discontinuous and overlapping dry river channels as the signature of the megafans. Overlapping frames, taken along track, were requested), and Mt. Etna, Sicily (weather was predicted to be clear over this volcano at the time of the ISS overpass. The massive volcanic edifice of Mt. Etna is the largest in Italy, and the most historically active. High resolution, near-nadir imagery of the volcano's summit and flanks was requested).
