ISS On-Orbit Status 05/12/12

All ISS systems continue to function nominally, except those noted previously or below. Saturday – Crew off duty.

Upon wakeup, FE-5 André Kuipers & FE-6 Don Pettit each completed another post-sleep session of the Reaction Self-Test (Psychomotor Vigilance Self-Test on the ISS) protocol, their 40th. [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.]

Kuipers continued his current extended session of the ESA ENERGY experiment. FE-6 Pettit also contributed a urine sample later in the day as Control Subject. [Activities included concluding the PFS (Pulmonary Function System) part of the experiment with disassembly of the PFM/PAM (Pulmonary Function Module/Photoacoustic Analyzer Module), GDS (Gas Delivery System), and MBS (Mixing Bag System), and stowage of the majority of the PFS hardware. Collection of a water sample from the PWD (Potable Water Dispenser) in the Lab and urine sampling (on 2nd void of the day) are continuing, as is adherence to the special ENERGY breakfast plus logging all ISS food & drinks consumed during ENERGY experiment performance from lunch and dinner on Day 1 until breakfast on Day 10. André wears an armband monitor, positioned on the right triceps where it started automatically on skin contact. The instrument must be worn for the entire 10-day ENERGY measurement period and removed only during showers or if needed during blood draws. Activities without the armband monitor on the triceps must be carefully logged. The monitor will be removed at the end of the 10-day period, then data will be downloaded from the device. Background: The observed loss of astronauts’ body mass during space flight is partly due to the systematic ongoing negative energy balance in micro-G, in addition to disuse. Unfortunately, the reason for such unbalanced match between intake and output is not clear, but appealing data suggest a relation between the degree of energy deficit and the exercise level prescribed as a countermeasure. Purpose of the ENERGY experiment is (1) to measure changes in energy balance during long term space flight, (2) to measure adaptations in the components of the Total Energy Expenditure TEE (consumption), and (3) to derive an equation for the energy requirements of astronauts. TEE is the sum of resting metabolic rate (RMR, measured), diet-induced thermogenesis (DIT, measured oxygen-uptake minus RMR) and activity-related energy expenditure (AEE, calculated).]

After breakfast, CDR Kononenko performed the routine inspection of the SM (Service Module) PSS Caution & Warning panel as part of regular Daily Morning Inspection.

The three crewmembers joined in conducting the regular weekly three-hour task of thorough cleaning of their home, including COL (Columbus Orbital Laboratory) and Kibo JPM (JEM Pressurized Module). [“Uborka”, usually done on Saturdays, includes removal of food waste products, cleaning of compartments with vacuum cleaner, damp cleaning of the SM dining table, other frequently touched surfaces and surfaces where trash is collected, as well as the sleep stations 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.]

As part of Uborka house cleaning, Oleg completed regular weekly maintenance inspection & cleaning of fan screens in the FGB (TsV2) plus Group E fan grilles in the SM (VPkhO, FS5, FS6, VP) and the BMP Harmful Contaminants Removal System grille in the SM.

The CDR also handled the routine daily servicing of the SOZh system (Environment Control & Life Support System, ECLSS) in the SM. [Regular daily SOZh maintenance consists, among else, of checking the ASU toilet facilities, replacement of the KTO & KBO solid waste containers, replacement of EDV-SV waste water and EDV-U urine containers and filling EDV-SV, KOV (for Elektron), EDV-ZV & EDV on RP flow regulator.]

André completed his weekly task of filling out his SHD (Space Headache) questionnaire. [He started this activity after his Soyuz launch and is continuing it on ISS (on an SSC/Station Support Computer) once every week (after daily logging in the first week). Neurologists from Leiden University are studying the question whether astronauts in space suffer from headaches. With the help of a simple questionnaire, André registers the headache episodes and the eventual accompanying symptoms. The results may help to characterize the frequency and characteristics of space headache and to develop countermeasure to prevent/minimize headache occurrence during the space flight],

Don had another time slot reserved for making entries in his electronic Journal on the personal SSC (Station Support Computer). [Required are three journaling sessions per week.]

At ~8:55am EDT, the crew held the 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 upcoming activities and any concerns about future on-orbit events.

At ~10:30am, Kuipers & Pettit conducted a ” crew handover”teleconference with the three Exp-31/Exp-32 crewmembers Padalka, Acaba & Revin at Baikonur, scheduled to launch on Soyuz 30S on 5/14 (~11:02pm EDT).

At ~11:05am, Don Pettit activated the MPC (Multi-Protocol Converter) routing to downlink the recording of his CFE-2 VG-2 (Capillary Flow Experiments 2 / Vane Gap 2) science session of 5/10, with POIC (Payload Operations & Integration Center) routing the onboard HRDL (High-Rate Data Link). Routing will be stopped by Don at ~3:25pm.

The crew worked out with their regular 2-hr physical exercise protocol on the CEVIS cycle ergometer with vibration isolation (FE-5, FE-6), TVIS treadmill with vibration isolation & stabilization (CDR), ARED advanced resistive exerciser (FE-5, FE-6) and VELO ergometer bike with load trainer (CDR). [FE-6 is on the special experimental SPRINT protocol which diverts from the regular 2.5 hrs per day exercise regime and introduces special daily sessions, followed by a USND (Ultrasound) leg muscle self scan in COL. No exercise is being timelined for Fridays. If any day is not completed, Don picks up where he left off, i.e., he would be finishing out the week with his last day of exercise on his off day. Today’s exercise calls for CEVIS (aerobic), with ARED+T2 (resistive+aerobic), T2, ARED+T2, CEVIS & ARED+T2 following in the next 5 days. If any day is not completed, Don picks up where he left off, i.e., he would be finishing out the week with his last day of exercise on his off day.]

GPS Failure: On 5/10, GPS-1 (Global Positioning System 1) of SIGI (Space Integrated GPS/Inertial Navigation System) locked up and stopped producing attitude information, potentially due to an internal hardware issue. Controllers on the ground power-cycled it twice (turned it off/on), but it did not come back on. GPS-1 is drawing power but is not communicating with the GNC MDM (Guidance, Navigation & Control Multiplexer/Demultiplexer) computer. There is another good spare onboard for an R&R (removal & replacement), as well as a degraded spare. On 5/14 (Monday), the crew will access the SIGI GPS and perform the R&R to increase redundancy in preparation for SpaceX launch and berthing if the decision to do it is made by tomorrow. Last April, when Burbank & Kuipers replaced the SIGI GPS in the Lab Aft Endcone, they ran into a couple of issues, and the R&R took eight hours of crew time split over two days using two crewmembers.

Tasks listed for Kononenko on the Russian discretionary “time permitting”job for today were –
• 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
• More preparation & downlinking of reportages (written text, photos, videos) for the Roskosmos website to promote Russia’s manned space program (max. file size 500 Mb).

BASS (Burning and Suppression of Solids, NASA): Thursday, 5/10, we burned 3 flat samples. The first test was 2-cm-wide SIBAL fabric (50% cotton-fiberglass blend) which was burned at a constant flow speed of 20 cm/s. Ignition and flame spread were nominal yielding a long yellow flame lasting approximately 30 seconds. The second test was a 1-cm-wide SIBAL fabric which was burned at a constant flow speed of 10 cm/s. The flame was very short and dim blue and burned for about 50 seconds. Don was able to finish the tests quickly enough so that he was able to burn one additional sample, a Nomex-blend fabric. We expected that ignition would be difficult to achieve, and indeed we were only able to observe a brief ignition flash and the flame could not be established. Finally, Don performed a fan and nitrogen calibration. The air flow and nitrogen flow are behaving nominally. PMMA sphere tests are scheduled to be performed after the writing of this message, and will be reported on next week.

BCAT-6 (Binary Colloidal Alloy Test 6): No report. [Colloids are particles as small as a few tens of nanometers (a thousandth of a thousandth of a millimeter) that are suspended in a medium, usually a liquid or a gas. The name “colloid”comes from the Greek word for “glue”, and expresses very important properties of colloids: when small and light enough, particles can be influenced in their behavior by forces of electromagnetic origin, and make them stick together, or repel each other depending on the configuration. Colloids are widely studied in science because the forces between particles can be controlled and tuned and because particles, while being small enough to be influenced by such forces, are big and slow enough to be seen with a relatively simple and inexpensive laboratory instrument like a microscope. This is why colloids are often studied as model for molecular systems (like standard gases or liquids) where molecules, the individual constituents, are much smaller than colloids and cannot be seen with light. As mentioned, forces between colloids can be tuned giving rise to a rich variety of phenomena. One of them is aggregation, which is when particles stick together and tend to form structures. Among the many ways to induce particle aggregation, one allows to do so by controlling the temperature of the solution in which the particles are immersed, thanks to very weak forces called “critical Casimir forces”that have been predicted more than 30 years ago but just partially verified in experiments. The objective of SODI COLLOID is to measure such forces and produce a controlled aggregation of tiny plastic particles. This would allow to shed light on critical Casimir forces and to make a step towards the fabrication of new nanostructured materials with remarkable optical properties for industrial applications.]

Despite the limited Ku band coverage, you were able to carefully step through and find the 4 wetting/dewetting angles planned for today’s test. By the way, thanks for the great request to have Mark W. summarize what we’re looking for before starting the test, and the super detailed descriptions after coming back from each LOS period. We’ve haven’t gotten the video back yet, but from your descriptions, we’re certain you found the 4 angles to within 0.5 deg or so. Finally, thanks for keeping us sharp with the “Stump the PI” question. From now on, we’re going to have to do some studying, like for a PhD. qualifier, prior to future CFE-2 runs!”

ENERGY (ESA): André, up to now everything is going extremely well. The science and ground teams are delighted that you are coping so well with the science constraints and would like to cordially thank you for that. It’s not over yet, but well done and keep on going The ground teams were glad to hear that you liked the special menu! Don, we appreciate very much your participation as control subject. The acquired data will be extremely valuable for the science team to be able to quantify the amount of Double Labeled Water that will be recycled in US system. [Background: In the ENERGY experiment, astronauts are invited to participate in a study that aimed to evaluate how much food is needed for astronauts during long-term space missions. To do so, the science team will measure every component or variable of the astronaut’s energy expenditure reflecting his energy needs. Those variables will be measured twice: up to 4 months before flight and after at least 3 months in space but 3 weeks before landing. The changes in the astronaut’s energy balance and expenditure will be measured, which will help in deriving an equation for energy requirements in weightlessness. This will contribute to planning adequate, but not excessive cargo supplies for food.]

GEOFLOW-2 (ESA): The repetition of the no-rotation run was performed successfully this time on 5/7, concluding the on-board operations of the GEOFLOWII campaign ! “Party time!”[Background: Everybody is familiar with liquids. In an average day we get to use, handle or drink water or other liquids. And everybody knows how fluids (that is liquids and gases) behave: when subjected to a net force, may be pressure, a temperature difference or gravity, they can move freely. Scientists have been studying how fluids move for centuries, and managed to write mathematical formulas that can describe and predict such movements. Unfortunately, these equations are extremely complex and only approximate solutions are known. As a result, our quantitative understanding of fluid movement is just partial. This is especially true for natural phenomena where the forces can be enormous and unpredictable, like in oceans or in the atmosphere. Or the interior of the earth, where rocks are exposed to pressures and temperatures so incredibly high that they slowly move and adapt their shape. That is, over hundreds of years rocks flow just like a very viscous liquid. Scientists try to study such flows but cannot observe them directly due to the fact that they take place deep beneath the surface of our planet. The only way is to have computers simulating those movements starting from the equations, but how to check whether computers are correct? This is what Geoflow II is trying to answer on board the International Space Station. Geoflow II is a miniature planet that has some of its essential ingredients: a fluid can freely move inside a spherical container that rotates, has temperature differences and has a simulated gravity directed towards the centre just like in a real planet. By taking pictures of the fluid movements, scientists are able to understand the essential characteristics of the flows and determine whether computer simulations are correct or whether they need to be refined and improved towards a better understanding of the elusive movements that take place inside our planet.]

These targets were primarily focused on the Northern Plains region of the United States, however two of these targets were taken off the coast of Newfoundland, in order to determine the camera’s feasibility in studying coastal climate change. Both of these targets (coast of Newfoundland) were over cloudy, so ISSAC will continue to image off the coast of Newfoundland in the coming days until suitable images are produced.

IV Gen (Intravenous Fluids Generation): No report.

JOURNALS (Behavioral Issues Associated with Isolation and Confinement, NASA): No report. [Studies conducted on Earth have shown that analyzing the content of journals and diaries is an effective method for identifying the issues that are most important to a person. The method is based on the reasonable assumption that the frequency that an issue or category of issues is mentioned in a journal reflects the importance of that issue or category to the writer. The tone of each entry (positive, negative, or neutral) and phase of the expedition also are variables of interest. Study results will lead to recommendations for the design of equipment, facilities, procedures, and training to help sustain behavioral adjustment and performance during long-duration space expeditions to the ISS, asteroids, the Moon, Mars, and beyond. Results from this study could help to improve the behavioral performance of people living and working under a variety of conditions here on Earth.]

NEUROSPAT (ESA/Study of Spatial Cognition, Novelty Processing and Sensorimotor Integration): No report. [During microgravity stay, the human body goes through multitude of physiological changes in order to accommodate to the new environment. As the brain is a master organ where major crucial processes take place, it is fundamental to understand how it manages adaptation for living in Space. One of the main purposes of Neurospat (NES) experiment is to focus on how microgravity environment influences cerebral activity of astronauts aboard ISS. For this, the global electrical activity of the brain of the astronaut is measured thanks to electroencephalogram (EEG) technique, while he or she is executing specific tasks through a computer as if it was a kind of videogame. In practice, the astronaut is wearing a specially equipped cap with passive, gel filled electrodes that are in contact with his/her scalp while he or she is performing the specific tasks that we have designed. These are visual-orientation perception and visuo-motor tracking tasks that may be encountered on a daily basis. The tasks allow the study of 5 cognitive processes: Perception, Attention, Memorization, Decision and Action. Besides there are also task-irrelevant images that are showed to the astronaut in order to assess how well he or she processes novel visual stimuli. The electrodes all over the scalp are linked to sensitive amplifiers that allow us to measure small variations of electrical potential between different regions of the scalp. These signals are in turn used to estimate activity in the cerebral cortex related to the task being performed. Also, they serve to identify the mental processes associated with these tasks and to localize in the brain the sources of the underlying neural activity. After analysis of the data we can better understand whether the novel environment of microgravity accompanied by a multitude of stressors may place an increased load on the cognitive capacity of the human brain and whether the sensory signals and motor responses of astronauts are processed and interpreted differently because a new reference frame.]

Seeing correctly the world is necessary to success our gestures, our actions, such as catching a ball, stepping an obstacle on the ground or passing through an opened door. In this experiment, we want to know if the strategies involved on Earth continue to be used when the astronaut is in a weightlessness environment for a long period. To investigate this question, the participant sees 3D scenes on the screen of a laptop such as a video game. The scene is a room with an opening which can vary in width. The task of the participant is to decide if yes or no he or she could pass through the aperture without rotating or scrunching the shoulders. The science team uses typical methods from psychophysics and manipulates several factors to highlight the strategies used by the participant. Then, the science team will compare the performances obtained on ground with those obtained onboard.]

[Background: The ROALD-2 experiment studies how the function of T-cells from the immune system are affected by microgravity and spaceflight. T-cells play an important role in controlling the immune systems response to infection. It has previously been shown that the immune response of astronauts can be reduced following spaceflight and it has also been shown that the activation of T-cells in culture is reduced in microgravity. A series of experiments on T-cells and other immune system cells have been previously performed by different scientific teams on Space Shuttle and the ISS over the last 30 years. The data from these individual experiments provides information which together can be used to understand the mechanisms by which gravity or the absence of gravity can affect T-cell function.]

This statement is in apparent contradiction with our experience: when we pour water in a glass and wait until all flows have disappeared and the temperature of the liquid is in equilibrium with that of the room, we see that water appears to be completely at rest. However, if we were able to see the individual molecules of water with a very powerful microscope, we would discover that they are incessantly moving and collide with each other following frantic, random paths even if the liquid appears to be quiescent at naked eye. Scientists are interested in observing and measuring such movements because they reveal important, practical information: how fast does heat propagates in a fluid? How fast do liquid mixtures mix? Such phenomena occur in absence of a macroscopic flow, that is when the fluid appears to be at rest, and are called heat and mass diffusion respectively. While the theoretical prediction of heat and mass diffusion is still quite challenging, its measurement is a standard laboratory practice, but may become extremely difficult or impossible when dealing with mixtures of many liquids, due to the fact that such measurement needs to be carried out when the fluid is quiescent, a condition sometimes impossible to achieve on ground. This is precisely the objective of the SODI DSC experiment carried out on board the International Space Station: the measurement of diffusion in mixtures of liquids. By using very sensitive optical techniques, it will be possible to measure mass diffusion, compare with current theories, and improve our present understanding of how molecules move in liquid mixtures. The results will be used by the large team of scientists involved in the project to try to understand which of the many existing theories for mass diffusion is correctly predicting the experimental behavior.]

VESSEL ID System (ESA): Nominal data acquisition with the NorAIS receiver. [Background: As the ISS circles Earth, it has been tracking individual ships crossing the seas beneath. An investigation hosted by ESA in COL module has been testing the viability of monitoring global maritime traffic from the station’s orbit hundreds of kilometers above since June 2010. The ship-detection system being tested is based on the AIS (Automatic Identification System), the marine equivalent of the air traffic control system. Astronauts were instrumental in enabling the COLAIS experiment, which is an in-orbit demonstration project of ESA’s General Support Technology Program. COL was not originally outfitted with VHF antennas to capture the AIS signals; they were installed on the outside of the module during a spacewalk in November 2009, with the remaining piece of hardware, the ERNOBox control computer, installed inside COL along with the NORAIS receiver in May 2010.- The two operational phases with the first receiver from Norway, or NORAIS, which is operated by FFI/Norway, have been extremely successful, with data telemetry received by the N-USOC, in Trondheim, Norway, via ESA’s COL-CC in Germany. Data has been received by NORAIS in almost continuous operation, and all modes of operation have worked extremely well. On a good day, approximately 400,000 ship position reports are received from more than 22,000 different ship identification numbers (Maritime Mobile Service Identity, or MMSI).– The NORAIS Receiver has a sample mode that can collect the raw signal, digitize it and send it to ground for analysis of signal quality, which is proving very helpful in making additional improvements/ refinements to the system. This is used both to investigate the signal environment and to evaluate the performance of new receiver technologies on the ground. Several hundred data sets have been collected and processed with new candidate algorithms for next generation receivers.– From the assessment of these data sets, an updated version of the decoder algorithm has been worked. The development benefits from the investigations of the sampled data and ongoing work in other ESA projects. The firmware was uploaded to the NORAIS Receiver through the station’s communications network. This upgrade #1 (“NORAIS Receiver FPGA firmware v18”), was activated on 1/20/2012.– The on-orbit data of the NORAIS Receiver v18 have been analyzed since and show very good results. The teams are confident in the operation and performance of v18 and have now preliminary results of the comparison of the performance of the upgraded NORAIS Receiver (v18) relative to the version operated prior to the upgrade (v16).– Changes of the signal environment on ISS can influence the number of correctly decoded messages, which makes it important to compare the results of this upgrade to a period running the old algorithm with a similar background level.– The daily averages are calculated for 11 days for both receiver versions. For the upgrade, the period considered for comparison is 1/21-1/31/2012, which are the first 11 days of operation. When selecting the period for the reference data it was important to find a period with the same background signal level as the 11 days with the upgraded NORAIS Receiver. The period from 11/27 – 12/7/2011 was. Even though the two 11 day periods are 45 days apart, the ship traffic should not be very different around the world, except for some regions in the north that may be hampered by sea ice.– The performance has been studied as the average number of decoded messages per day for the current upgrade v18 of the firmware and the original NORAIS Receiver software. The improvement is the ratio of these numbers (so average numbers of messages per day before the upgrade divided by number of messages after the upgrade). The number of messages from ships in various geographic areas shows a variation in the ratio of messages from 1.2 to 2.0, whereas the ratio of MMSI’s ranges from 1.1 to 1.9. The improvement in the Mediterranean is almost a factor of 2.0 in number of messages, and more than 1.6 in number of distinct ships per day. The improvement in other high-traffic zones, at the Gulf of Mexico and East Asia, is even higher.]

VESSEL IMAGING (ESA): “Thank you, Don, for your second VESSEL IMAGING scan session on 5/7! The science team confirmed good images.””[Background: It is known that the ability of blood vessels to vasoconstrict – the ability of the muscular vessel wall to narrow the diameter of the blood vessel – is impaired during and after a human has been in space. “Vessel Imaging” is using the Ultrasound scanner on board the ISS to take images of the five different blood vessels in the lower abdomen and in the legs to study what changes occur to cause the blood vessels to be less able to vasoconstrict. For each vessel, a 5 second scan is performed to observe the blood vessel during several heart beats, followed by a scan where the ultrasound scan-head is tilted to allow a “cut through the blood vessel wall”. The same scans are also performed before flight, and these pre-flight images are used as the baseline to which the in-flight data is compared with. The images are analyzed to detect any changes in the blood vessel wall properties, such as wall thickness, elasticity or structure, changes in the size of the blood vessel or blood flow (volume) while the crewmember is in orbit.]
