ISS On-Orbit Status 09/05/10

All ISS systems continue to function nominally, except those noted previously or below. Sunday – crew rest day. Ahead: Week 14 of Increment 24. >>>On this day in 1977, Voyager 2, the first of two deep-space explorers, took off on its unending cosmic voyage. Also on this day in 1984, Space Shuttle Discovery landed safely from its maiden flight, STS-41D, the 12th Shuttle mission, with the crew of Henry Hartsfield, Michael Coats, Richard Mullane, Steven Hawley, Judith Resnik & Charles Walker – all of them on their first spaceflight except for Hank who was on his second.<<<

At wake-up, CDR Alex Skvortsov 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 in gaps between the BZh Liquid Unit and the oxygen outlet pipe (filter FA-K) plus hydrogen outlet pipe (filter FA-V). [The CDR again inspects the filters before bedtime tonight, currently a daily requirement per plan, with photographs to be taken if the filter packing is discolored.]

Upon wake-up, FE-2 Tracy Caldwell-Dyson & FE-4 Doug Wheelock performed a new session with the Reaction Self Test (Psychomotor Vigilance Self Test on the ISS) protocol. [The RST is done twice daily (after wakeup & before bedtime) for 3 days prior to the sleep shift, the day(s) of the sleep shift and 5 days following a sleep shift. The experiment consists of a 5-minute reaction time task that allows crewmembers to monitor the daily effects of fatigue on performance while on ISS. The experiment provides objective feedback on neurobehavioral changes in attention, psychomotor speed, state stability, and impulsivity while on ISS missions, particularly as they relate to changes in circadian rhythms, sleep restrictions, and extended work shifts.]

FE-3 Mikhail Kornienko completed the routine daily servicing of the SOZh system (Environment Control & Life Support System, ECLSS) in the SM (Service Module), including the weekly collection of the toilet flush (SP) counter and water supply (SVO) readings for calldown to TsUP-Moscow. [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.]

Misha also checked up on the Russian POTOK-150MK (150 micron) air filter unit of the SM’s SOGS air revitalization subsystem, gathering weekly data on total operating time & “On” durations for reporting to TsUP.

Doug Wheelock & FE-6 Shannon Walker started their second six-day SOLO (Sodium Loading in Microgravity) sessions, which entails a series of diet intake loggings, body mass measurements and blood & urine samplings in two session blocks. Doug is now on High Salt diet, with daily diet log entries. [SOLO is composed of two sessions of six days each. From Day 1 to 5 (included) Wheels & Shannon have to eat special diet (for Wheels: Session 1 – Low salt diet; Session 2 – High salt diet which corresponds to normal ISS diet salt level; for Shannon: first High salt, then Low salt). 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 logged daily 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. Body mass is measured with the SLAMMD (Space Linear Acceleration Mass Measurement Device) on Days 4 & 6. Blood samples are taken on Day 5, centrifuged & inserted in MELFI (Minus Eighty Laboratory Freezer for ISS) and also measured with the PCBA. 24-hr urine collections will be performed on Day 5, with sample insertion in MELFI. Background: SOLO, a NASA/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. 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.]

CDR, FE-2, FE-4 & FE-5 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), Tracy at ~3:35am and ~1:25pm, Alex at ~6:40am, Fyodor at ~8:00am, Wheels at ~11:15am EDT.

The crew worked out on today’s 2-hr physical exercise protocol on the TVIS treadmill with vibration isolation (CDR, FE-3/2x, FE-5), ARED advanced resistive exercise device (CDR, FE-2, FE-4, FE-6), T2/COLBERT advanced treadmill (FE-2, FE-4, FE-6) and VELO ergometer bike with bungee cord load trainer (FE-5). [T2 snubber arm inspection is no longer needed after the last T2 session of the day, but it is now regularly being done once a week after the last T2 session.]

Jobs listed for Skvortsov, Fyodor & Kornienko today on the Russian discretionary “time permitting” task list were –
  • Another ~30-min. run of the GFI-8 "Uragan" (hurricane) earth-imaging program with the NIKON D3X digital camera photography with Sigma AF 300-800mm telelens, shooting the Sochi area, Kolka glacier, Port Olia, and e the extensive fires in the Volgograd and Samara regions;
  • A ~30-min. session for Russia's EKON Environmental Safety Agency, making observations and taking KPT-3 aerial photography of environmental conditions on Earth using the NIKON D3X camera with the RSK-1 laptop, and
  • A ~15-min. photography session for the DZZ-13 “Seiner” ocean observation program, obtaining NIKON D3 photos with Nikkor 80-200 mm lens and the SONY HD video camcorder on oceanic water blooms in the Southeast Atlantic area, then copying the images to the RSK-1 laptop.

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