US Holiday: Memorial Day.

Ahead: Week 6 of Increment 17.

FE-2 Garrett Reisman worked on the EDR (European Drawer Rack) in the COL (Columbus Orbital Laboratory), installing a restraint on the EDR seat track for the PCDF EU (Protein Crystallization Diagnostic Facility Electronic Unit). Later, the PCDF EU was activated by the ground with crew support.

Afterwards, Reisman performed the periodical status and shell temperature check In the JLP (Japanese Experiment Module Experiment Logistics Module Pressurized Section) from the MKAM (Minimum Keep-Alive Monitor).

The CDR performed major 1.5-hour IFM (in-flight maintenance) in the Service Module (SM) by removing one of the module's eight 800A storage batteries (#3) and replacing it with a spare Blok 800A. The removed unit was prepared for disposal on the next Progress. (The ZRU charge/discharge unit #3 was deactivated by TsUP/Moscow beforehand and later reactivated. The new battery #3 is currently being conditioned in Cycle mode. This restores the full set of eight SM batteries to operation.)

FE-1 Oleg Kononenko conducted the long-planned transfer of US condensate water from four CWCs (Contingency Water Containers) to the empty WCP3 tank of the ATV (Automated Transfer Vehicle)'s water delivery system (WDS), first assembling the equipment with a pump for purging air from the tank and conducting standard leak checking for one hour, then activating the transfer. (The WCP1 tank contains potable water. ATV water tank #2 integrity check is scheduled for 5/29.)

Reisman set up the SLEEP experiment for end-of-increment Actiwatch downloading and initializing, then marked his Actiwatch and stowed it. (The NASA/JSC experiment is supported by the HRF1 laptop. To monitor the crewmembers' sleep/wake patterns and light exposure, their special Actiwatch device measure the light levels encountered by them as well as their patterns of sleep and activity throughout the Expedition.)

Volkov & Kononenko spent about three hours working jointly on cargo transfers & stowage from Progress 29P, tracking the moves in the IMS (Inventory Management System).

Reisman had two hours for unpacking and stowing US cargo items delivered on 29P, as per the 29P Unpack List.

Sergey & Garrett performed their third standard 30-min Shuttle RPM (R-bar Pitch Maneuver) skill training, using the DCS-760 digital still cameras with 400 & 800mm lenses to take in-cabin target imagery. Afterwards, the obtained OBT (onboard training) images were downlinked to the ground for analysis (~11:45am). (The RPM drill prepares crewmembers for the bottom-side mapping of the Orbiter at the arrival of the Shuttle (STS-124/1J) on 6/2. During the RPM at ~600 ft from the station, the 'shooters' have only ~90 seconds for taking high-resolution digital photographs of all tile areas and door seals on Discovery, to be downlinked for launch debris assessment. Thus, time available for the shooting will be very limited, requiring great coordination between the two headset-equipped photographers and the Shuttle pilot.)

Also in preparation for the RPM photo shoot, the FE-2 checked out all four DCS (Digital Camera System) cameras by taking blank images, storing them on a PCMCIA flash memory card and later downlinking them to MCC-Houston for analysis. (Blank images are used to identify 'dead' pixels for each camera.)

In the Soyuz TMA-12/16S spacecraft, docked at the DC1 Docking Compartment, Volkov turned on the spacecraft's gas analyzer (GA), a periodic procedure to monitor the atmosphere of the CRV (Crew Return Vehicle).

Performing some outfitting in the SM, the CDR installed a Progress-delivered protective cover on the PPS-31 Systems Power Panel of the SUBA Onboard Equipment Control System.

The FE-2 had another hour set aside for his departure preparations.

The CDR completed the routine maintenance of the SM's 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 also 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 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 (FE-2), TVIS treadmill (CDR, FE-1), RED resistive exercise device (CDR, FE-1, FE-2), and VELO bike with bungee cord load trainer (CDR, FE-1).

Afterwards, Kononenko 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).

At ~4:55am EDT, Garrett conducted a 15-min teleconference with ground specialists to discuss JLP stowage issues.

At ~10:30am, the CDR & FE-1 downlinked a Russian PAO TV message of greetings to TsUP-Moscow for the participants of the Star Relay Race Competition

At 1:30pm, Volkov & Kononenko held a regular PMC (Private Medical Conference) to discuss their physical exercise with a specialist via Ku- & S-band.

No CEO (Crew Earth Observations) targets uplinked for today.
