All ISS systems continue to function nominally, except those noted previously or below.
Sunday – crew rest day. Ahead: Week 13 of Increment 24. This morning at 8:09am EDT, the ISS (specifically its FGB “Zarya” module) completed 67,500 orbits of the Earth, having covered a distance of 2.91 billion km (1.82 billion st.miles) in 4300 days, or about 5 times the Hohmann travel distance to Mars. [The 19,300-kg/42,600-lbs Zarya (“Dawn”) was launched on a Russian/Khrunichev Proton from Baikonur almost 12 years ago, on 11/20/1998, as the first element of the multi-national space station.] Upon wake-up, FE-6 Walker completed another session with the Reaction Self Test (Psychomotor Vigilance Self Test on the ISS) protocol.
[The RST is performed 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.] Shannon concluded her 3
rd (FD75) ICV (Integrated Cardiovascular) Ambulatory Monitoring session, doffing the two Actiwatches and HM2 (Holter Monitor 2) about 24 hrs after the end of yesterday’s “midpoint” activity (~2:10pm EDT). Data download from all devices to the HRF (Human Research Function) PC1 laptop will be scheduled later.
[For the ICV Ambulatory Monitoring session, during the first 24 hrs (while all devices are worn), ten minutes of quiet, resting breathing are timelined to collect data for a specific analysis. The nominal exercise includes at least 10 minutes at a heart rate ≥120 bpm (beats per minute). After 24 hrs, the Cardiopres/BP is doffed and the HM2 HiFi CF Card and AA Battery are changed out to allow continuation of the session for another 24 hours, with the Makita batteries switched as required. After data collection is complete, the Actiwatches and both HM2 HiFi CF Cards are downloaded to the HRF PC1, while Cardiopres data are downloaded to the EPM (European Physiology Module) Rack and transferred to the HRF PC1 via a USB key for downlink.] CDR Skvortsov performed 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.] Alex 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.
Upon TsUP GO FE-3 Kornienko was to use pressurized O
2 from Progress 38P oxygen stores for another refresh of the ISS cabin for about an hour.
[The Elektron O2 generator is currently off.] FE-4 Wheelock & FE-6 Walker prepared the diet logs for their upcoming first six-day SOLO (Sodium Loading in Microgravity) sessions, which will entail 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) Wheels & Shannon will 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.] 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 large glaciers of the South Patagonia ice field (left of flight path), the Uppsala glacier in nadir, the Viedma glacier, and the Chico glacier;
- 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 South-West Atlantic area, then copying the images to the RSK-1 laptop.
The crew worked out on today’s 2-hr physical exercise protocol on the CEVIS cycle ergometer with vibration isolation (FE-4, FE-6), TVIS treadmill with vibration isolation (CDR, FE-3, FE-5), ARED advanced resistive exercise device (FE-2, FE-3, FE-4, FE-5, FE-6), T2/COLBERT advanced treadmill (FE-2) and VELO ergometer bike with bungee cord load trainer (CDR).
[T2 snubber arm inspection is no longer needed after every T2 session but is regularly being done after the last T2 session of the day.] No CEO (Crew Earth Observation) photo targets uplinked for today.
