NASA ISS On-Orbit Status 13 February 2011

image All ISS systems continue to function nominally, except those noted previously or below. Sunday - Crew rest day. Ahead: Week 13 of Increment 26.

FE-4 Kondratyev conducted the regular daily early-morning check of the aerosol filters at the Russian Elektron O2 generator which Maxim Suraev had installed on 10/19/09 in gaps between the BZh Liquid Unit and the oxygen outlet pipe (filter FA-K) plus hydrogen outlet pipe (filter FA-V). [Before sleeptime, Dmitri will inspect the filters again, currently a daily requirement per plan, with photographs to be taken if the filter packing is discolored.]

CDR Kelly transferred three urine-filled EDV-U containers (#902, #936, #966) to the aft end of the SM (Service Module).

FE-1 Kaleri then set up the usual pumping equipment (Kompressor-M #41, hoses, adapters) in the SM and transferred the urine from the EDV-Us to the BV1 Rodnik water storage tank of Progress M-07M/39P (#407), docked at SM Aft. After the containers were emptied, Alex performed a flush using water from an EDV-SV waste water container. Scott later returned the empty EDV-Us to the USOS (US Segment). [Each of the spherical Rodnik tanks BV1 & BV2 consists of a hard shell with a soft membrane (bladder) composed of elastic fluoroplastic. The bladder is used to expel water from the tank by compressed air pumped into the tank volume surrounding the membrane and is leak-tested before urine transfers, i.e., with empty tanks, the bladders are expanded against the tank walls and checked for hermeticity.]

FE-5 Nespoli cleared the COL (Columbus Orbital Laboratory) end cone at stowage locations D4 & O4 to make room for SLAMMD (Space Linear Acceleration Mass Measurement Device) operations, then set up the SLAMMD hardware for its use tomorrow by Kelly, Coleman & Nespoli.

Paolo also completed the 2nd day of his 2nd SOLO (Sodium Loading in Microgravity) session, which entails a series of diet intake loggings, body mass measurements and blood & urine samplings in two session blocks. [SOLO is composed of two sessions of six days each. From Day 1 to 5 (included) Paolo will have to eat special diet (Session 1: High salt diet which corresponds to normal ISS diet salt level and Session 2: Low salt diet). Solo Diet starts with breakfast on Day 1. Day 6 of each session is diet-free. For both diets, specially prepared meals are provided onboard. All three daily meals are being logged on sheets stowed in the PCBA (Portable Clinical Blood Analyzer) Consumable Kit in the MELFI (Minus-Eighty Laboratory Freezer for ISS) along with control solution and cartridges for the PCBA. SOLO, an ESA/German experiment from the DLR Institute of Aerospace Medicine in Cologne/Germany, investigates the mechanisms of fluid and salt retention in the body during long-duration space flight. Body mass is measured with the SLAMMD (Space Linear Acceleration Mass Measurement Device). Blood samples are taken with the PCBA. Background: The hypothesis of an increased urine flow as the main cause for body mass decrease has been questioned in several recently flown missions. Data from the US SLS1/2 missions as well as the European/Russian Euromir `94 & MIR 97 missions show that urine flow and total body fluid remain unchanged when isocaloric energy intake is achieved. However, in two astronauts during these missions the renin-angiotensin system was considerably activated while plasma ANP concentrations were decreased. Calculation of daily sodium balances during a 15-day experiment of the MIR 97 mission (by subtracting sodium excretion from sodium intake) showed an astonishing result: the astronaut retained on average 50 mmol sodium daily in space compared to balanced sodium in the control experiment.]

Oleg conducted the routine daily servicing of the SOZh system (Environment Control & Life Support System, ECLSS) in the SM, including the weekly collection of the toilet flush (SP) counter and water supply (SVO) readings for calldown to TsUP-Moscow. [This includes 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].

FE-2 also performed the weekly checkup on the Russian POTOK-150MK (150 micron) air filter unit of the SM's & FGB's SOGS air revitalization subsystem, gathering weekly data on total operating time & "On" durations for reporting to TsUP.

Before sleeptime, Skripochka will prepare the Russian MBI-12 payload and start his 11th Sonokard experiment session, using a sports shirt from the Sonokard kit with a special device in the pocket for testing a new method for acquiring physiological data without using direct contact on the skin. Measurements are recorded on a data card for return to Earth. [Sonokard objectives are stated to (1) study the feasibility of obtaining the maximum of data through computer processing of records obtained overnight, (2) systematically record the crewmember's physiological functions during sleep, (3) study the feasibility of obtaining real-time crew health data. Investigators believe that contactless acquisition of cardiorespiratory data over the night period could serve as a basis for developing efficient criteria for evaluating and predicting adaptive capability of human body in long-duration space flight.]

CDR, FE-2 & FE-6 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 ~9:50am, Scott at ~11:25am, Cady at ~4:15pm EST.

The crewmembers worked out with their regular 2-hr physical exercise on the CEVIS cycle ergometer with vibration isolation (FE-5, FE-6), TVIS treadmill (FE-1, FE-2, FE-4), ARED advanced resistive exerciser (CDR, FE-5, FE-6), T2/COLBERT advanced treadmill (CDR) and

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