Saturday - off-duty day for CDR Volkov, FE-1 Kononenko and FE-2 Reisman.

The crew performed the regular weekly three-hour task of thorough station cleaning. ("Uborka", usually done on Saturdays, includes removal of food waste products, cleaning of compartments with vacuum cleaner, damp cleaning of the Service Module (SM) dining table, other frequently touched surfaces and surfaces where trash is collected, as well as the FE's sleep station with a standard cleaning solution; also, fan screens and grilles are cleaned to avoid temperature rises. Special cleaning is also done every 90 days on the HEPA (high-efficiency particulate air) bacteria filters in the Lab.)

The crew also performed regular maintenance inspection & cleaning on fan grilles in the FGB (FS5 & FS6, TsV2), SM (VPkhO & VPrK), DC1 (V3) and in the COL (Columbus Orbital Laboratory) for ESA.

Additionally, CDR Volkov conducted the routine maintenance of the SOZh system (Environment Control & Life Support System, ECLSS) in the SM, including ASU toilet facilities systems/replaceables, the weekly collection of the toilet flush (SP) counter and water supply (SVO) readings for calldown to TsUP and today also the periodic cleaning of the pre-filter of the POTOK air filtration system. (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.)

At ~10:05am EDT, the crewmembers held their regular WPC (Weekly Planning Conference) with the ground, discussing next week's "Look-Ahead Plan" (prepared jointly by MCC-H and TsUP/Moscow timeline planners) via S-band/audio, reviewing the monthly calendar, upcoming activities, and any concerns about future on-orbit events.

The three crewmembers 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, Garrett transferred the crew's exercise data file to the MEC 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).

The Russian crewmembers had their weekly PFCs (Private Family Conferences) via S-band/audio and Ku-band/MS-NetMeeting application (which displays the uplinked ground video on an SSC laptop), Oleg at ~7:25am, Sergey at ~8:30am.

At ~3:00am, Oleg Kononenko held a telephone conference with Conference with Vladimir Stepanovich Krivtsov, the President of Kharkov Aviation Institute. Oleg is a KhAI alumnus. (Every year at the end of May KhAI alumni, employees of enterprises and organizations of Russia, Ukraine, and other countries, also KhAI faculty and students, are celebrating a holiday, the Khai Day, which takes place on 5/24.)

At ~11:30am, the crew downlinked two PAO TV messages of greetings, one for veteran cosmonaut V. I. Tereshkova, the other for the 10th International Festival Childhood without Borders. (The city of Yaroslavl is getting ready for the 45th anniversary celebration of the first female-cosmonaut flight into space. The Vostok-6 space vehicle with Valentina Vladimirovna Tereshkova on board was launched into near-Earth orbit on June 16, 1963. The flight continued for almost three days. At the same time with Vostok-6, Vostok-5 with Valery Bykovski was on orbit as well. The International festival 'Childhood without Borders' is held in Moscow on an annual basis. This festival is an open forum to demonstrate abilities and creativity of children, children's organizations and groups, and adults working with children to support their creative forces and initiative. On the eve of 6/1, the International Children's Day, children and adults from various regions of Russia and abroad get together in Moscow to demonstrate a need for a constructive dialog regarding the present and the future for children and young adults.)

New items on the discretionary task lists for Garrett, Sergey and Oleg for today were unpacking of 29P US cargo & CHeCS rack audit/survey by Reisman, and another EKON earth observation session for Volkov.
