Crew rest day.

Wake/sleep cycle for the crew was adjusted to 1:00am-4:30pm EST.

For today's Voluntary Science program, CDR Whitson continued her work with the InSPACE-2 (Investigating the Structure of Paramagnetic Aggregates from Colloidal Emulsions) experiment in the MSG (Microgravity Science Glovebox), conducting runs #28, #29 and #30, investigating low frequency behavior of the lowest concentration magnetorheological (MR) fluid, exchanging video tapes after each run, then switching to the highest concentration (vial #4) and finally powering the MSG down. (The activity included an EPO (Education Payload Operation) Demo for grades 9-12. InSPACE obtains basic data on MR fluids, i.e., a new class of "smart materials" that can be used to improve or develop new brake systems, seat suspensions robotics, clutches, airplane landing gear, and vibration damper systems. The colloidal (dispersed) particles are contained in CAs (Coil Assemblies) in the MSG that subject them to electric fields at certain strength and frequencies. The desired strong dipolar interaction between the small colloidal particles can be achieved in micro-G simply with an external magnetic field being turned on and off. On the ground, the flow properties (rheology) of many materials, especially those making up consumer products like detergents, fabric softeners, toothpaste and paints, are similarly controlled, though not by magnetic fields but by adding a polymer. It now appears, for example, that new formulations of fabric softeners may perform better in space than on earth. )

FE-2 Leo Eyharts broke out and set up the PFE-OUM (Periodic Fitness Evaluation-Oxygen Uptake Measurement) equipment on the HRF-2 (Human Research Facility 2) rack, including the HRF PFM/PAM (Pulmonary Function Module/Photoacoustic Analyzer Module), Mixing Bag System and GDS (Gas Delivery System). Data collection on Leo as subject, with Peggy as operator, is scheduled tomorrow. (The PFE-OUM experiment, using the CEVIS ergometer for workout, demonstrates the capability of crewmembers to perform periodic fitness evaluations with continuous oxygen consumption measurements within 14 days after arrival on ISS, and once monthly during routine PFEs. Once the capability of the pulmonary function system (PFS) to perform PFEs is verified, crewmembers will be able to integrate their monthly PFE with oxygen consumption measurements to fulfill the requirement for cardiovascular fitness evaluations during long-duration space flight.)

FE-1 Yuri Malenchenko completed the routine servicing of the SOZh system (Environment Control & Life Support System, ECLSS) in the Service Module (SM). (Regular daily SOZh maintenance consists, among else, of checking the ASU toilet facilities, replacement of the KTO & KBO solid waste containers and replacement of EDV-SV waste water and EDV-U urine containers.)

Working off his discretionary 'time permitting' task list, the FE-1 performed the periodic downloading of accumulated log files from the Russian BSMM (Payload Matching Unit/computer) to the 'Wiener' power laptop, then transferred two log files to US OCA for downlink.

Also on Yuri's task list for today was the regular check of the Japanese experiment GCF-JAXA (Granada Crystallization Facility) in the Russian TBU incubator, maintained at +20 degC, including a temperature checkup on its ART (automatic temperature recorder). (This is a daily monitoring/temp checking, carried on the Russian voluntary task list for the duration of Expedition 16.)

The crewmembers completed their regular 2.5-hr. physical workout program (about half of which is used for setup & post-exercise personal hygiene) on the TVIS treadmill (CDR, FE-1), RED resistive exercise device (CDR, FE-2) and VELO bike with bungee cord load trainer (FE-1, FE-2). The CEVIS is set up for tomorrow's PFE-OUM session by Leo.

Peggy then transferred the crew's exercise data file to the MEC (Medical Equipment Computer) for downlink, as well as the daily wristband HRM data of the workouts on RED, followed by their erasure on the HRM storage medium (done six times a week).

At ~3:30am EST, the crew participated in a TV downlink of greetings for replay to the participants of the 12th World Russian People's Council taking place in the State Kremlin Palace in Moscow from 2/20 to 2/22. (An assembly of children and young people, the Congress is devoted to the theme 'Future Generations - Russia's National Treasure'. For the first time in the history of the World Russian People's Council since 1993, the majority of the forum participants will be young people from all corners of Russia. President V.V. Putin and Alexy II, Patriarch of Moscow and All of Russia, are expected to address the Council with their welcome greetings. Over 5000 people will participate in the Congress, to be greeted by the ISS crew: ' €¦Our society needs you to be bold, dynamic, thinking, searching! You will be implementing ideas of Tsiolkovsky, Korolev, and other space pioneers. We also congratulate students of the Bauman Moscow State University who won the Innovation Project 2007 competition in the Youths and Space category. Today, our space home is orbiting the Earth, and tomorrow these words from a song will become a reality: 'Fly around the Earth and go to Mars!' Mars is awaiting you!')

MT Translation: Later today (4:20pm-6:20pm) the Mobile Transporter cart will be translated on its rails by ground commanding from WS7 (Worksite 7) to WS4 to provide added MMOD (Micrometeoroid/Orbital Debris) protection of the TUS (Trailing Umbilical System), as before Flight 1E. During the move, Russian thrusters will be inhibited (3:49pm-6:25pm) due to loads constraints.

WDS Update: An updated Water Delivery System 'cue card' was uplinked for the crew's reference. The new card (16-0018T) lists 36 CWCs (Contingency Water Containers; ~1295.1 L total) for the four types of water identified on board: technical water (695.3 L, for Elektron, flushing, hygiene), potable water (559.5 L), condensate water (40.2 l), waste/EMU dump and other (0 L). Of the 36 containers, nine CWCs with technical water (251.1 L) cannot be used until cleared for Wautersia bacteria, and 10 CWCs with potable water (427 L), transferred from Atlantis, are not cleared for use pending analysis of samples returning on 1E.

Weekend Voluntary Science: Two optional activities for the voluntary 'Saturday Science' program for next weekend (2/23-24) were suggested to Peggy for her choice. Selection is required by tonight. (The two choices are: (1) InSPACE-2 - two experiment runs on 2/23 and three runs on 2/24; (2) EPO - Careers Demo (Identify all the different steps crewmembers have taken to get to where they are today. Identify all the different NASA careers that work together to prepare an astronaut for spaceflight. Objective: to motivate students to strive for a career in science, technology, engineering, and mathematics and to someday work for NASA.)
