Sep 22, 2017

Marrow: Today a 52S crewmember conducted breath and ambient air sample collections for the Marrow investigation, which looks at the effect of microgravity on bone marrow. It is believed that microgravity, like long-duration bed rest on Earth, has a negative effect on the bone marrow and the blood cells that are produced in the bone marrow. Sarcolab-3: A USOS subject conducted the knee protocol for Sarcolab-3. The subject ingressed the Muscle Atrophy Research & Exercise System (MARES) chair, installed the knee Electromyography (EMG) electrodes and began the knee exercise protocol, while an operator collected ultrasound images of the subjects right leg. The crew deconfigured and stowed MARES, which was originally on the timeline for next Monday. Todays activity concludes five consecutive days of joint research, where three crewmembers conducted a series of ankle and knee configuration exercises. The data collected for Sarcolab-3 will be compared to pre and post flight measurements to assess the impact of hypothesized microgravity induced muscle loss. Myotendinous and Neuromuscular Adaptation to Long-term Spaceflight (Sarcolab) investigates the adaptation and deterioration of the soleus (calf muscle) where it joins the Achilles tendon, which links it to the heel and carries loads from the entire body. Muscle fiber samples are taken from crew members before and after flight, and analyzed for changes in structural and chemical properties. MRI and ultrasound tests and electrode stimulation are conducted to help assess muscle and tendon changes caused by microgravity exposure. Human Research Program (HRP) Collections (Biochemical Profile, Repository): Today a 52S crewmember collected blood sample collections in support of the Biochemical Profile and Repository experiments. With operator assistance, the subject is collecting blood samples and the samples will be processed for double spin operations using the Refrigerated Centrifuge prior to being placed in the Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI). The Biochemical Profile experiment tests blood and urine samples are obtained from astronauts before, during, and after spaceflight. Specific proteins and chemicals in the samples are used as biomarkers, or indicators of health. Post-flight analysis yields a database of samples and test results, which scientists can use to study the effects of spaceflight on the body. Repositoryis a storage bank used to maintain biological specimens over extended periods of time and under well-controlled conditions. This repository supports scientific discovery that contributes to our fundamental knowledge in the area of human physiological changes and adaptation to a microgravity environment and provides unique opportunities to study longitudinal changes in human physiology spanning many missions. Advanced NanoStep: The crew completed setup activities prior to installing the Advanced NanoStep cartridge in the Solution Crystallization Observation Facility (SCOF). JAXAs Advanced NanoStep experiment investigates the relationship between impurity incorporation mechanisms and the quality of obtained protein crystals should be clarified for the progress to an advanced stage of the space utilization for structure-based drug design. In this mission, we observe the protein crystal growth surfaces of glucose isomerase crystals in space in the presence of various impurities with the use of a Michelson interferometer. In addition, we also clarify the crystal surface morphology on the molecular step level by using the laser confocal microscope. We evaluate the crystal quality of the returned crystals. Electrostatic Levitation Furnace (ELF) Chamber Cap Removal and Cartridge Installation: The crew removed the ELF chamber cap from the chamber hole and installed the sample cartridge. ELF is an experimental facility designed to levitate, melt and solidify materials by container less processing techniques using the electrostatic levitation method. With this facility, thermophysical properties of high temperature melts can be measured and solidification from deeply undercooled melts can be achieved. Fluids Integrated Rack (FIR) Light Microscopy Module (LMM) Cable Re-clock: During last weeks LMM control box replacement, two cables were left disconnected due to physical interference of back shells on adjacent power/data cables. Today, the crew re-clocked the connector that mates to the LMM Control Box to remove the interference of the cable connection. LMM is a modified commercial, highly flexible, state-of-the-art light imaging microscope facility that provides researchers with powerful diagnostic hardware and software onboard the International Space Station (ISS). Device for the study of Critical Liquids and Crystallization (DECLIC) Hose Reseat: The crew removed and reconnected the DECLIC supply and return hoses to troubleshoot the moderate temperature loop flow issues to the DECLIC Directional Solidification Insert (DSI). DECLIC is a multi-user facility utilized to study transparent media and their phase transitions in microgravity onboard the International Space Station (ISS). The DSI portion of the DECLIC multi-user facility experiment will study a series of benchmark experiments on transparent alloys that freeze like metals under microgravity onboard the International Space Station (ISS) using SCN (succinonitrile-a transparent organic substance in the liquid state that is used to study the phenomena related to solidification processes) based alloys. The DSI insert will be installed for the second run of the three series of DECLIC experiments. RED Camera Calibration: The crew created calibration files for the RED Dragon Camera in support of the Earth Imagery from ISS investigation. The Earth Imagery from ISS investigation will help create a series of videos, showcasing Earth from space. These videos will be taken with cameras on the International Space Station in 6K hi-resolution, then integrated into videos for screensavers for public enjoyment, exploration, and engagement. Todays Planned Activities All activities are on schedule unless otherwise noted.

Sarcolab-3: After successfully completing three days of the ankle configuration exercises, today USOS and Russian subjects conducted the knee protocol for Sarcolab-3. The subjects ingressed the Muscle Atrophy Research & Exercise System (MARES) chair, installed the knee Electromyography (EMG) electrodes and began the knee exercise protocol, while an operator collected ultrasound images of the subjects right leg. The data collected for Sarcolab-3 will be compared to pre and post flight measurements to assess the impact of hypothesized microgravity induced muscle loss. Myotendinous and Neuromuscular Adaptation to Long-term Spaceflight (Sarcolab) investigates the adaptation and deterioration of the soleus (calf muscle) where it joins the Achilles tendon, which links it to the heel and carries loads from the entire body. Muscle fiber samples are taken from crewmembers before and after flight, and analyzed for changes in structural and chemical properties. MRI and ultrasound tests and electrode stimulation are conducted to help assess muscle and tendon changes caused by microgravity exposure. Payload On-Orbit Still Shots for Utilization and Maintenance (POSSUM) Payload Photo: The crew took digital photos of all payload racks in the US Lab, JEM Pressurized Module (JPM), and Columbus module to document configuration changes. Fine Motor Skills (FMS): A crewmember completed a FMS session which was executed on a touchscreen tablet, where the subject performs a series of interactive tasks. The investigation studies how fine motor skills are affected by long-term microgravity exposure, different phases of microgravity adaptation, and sensorimotor recovery after returning to Earth gravity. The goal of FMS is to answer how fine motor performance in microgravity trend/vary over the duration of a six-month and year-long space mission; how fine motor performance on orbit compare with that of a closely matched participant on Earth; and how performance trend/vary before and after gravitational transitions, including the periods of early flight adaptation, and very early/near immediate post-flight periods. Tropical Cyclone Maria: The crew setup and configured camera settings, before capturing images of Hurricane Maria to support the Tropical Cyclone investigation. The Tropical Cyclone investigation is used to capture images of tropical cyclones and hurricanes that are rated at Category 3 or greater on the Saffir-Simpson scale. A pseudo-stereoscopic method is used to determine the altitudes of the cloud tops near the center (eye) of a cyclone by precisely tracking the apparent positions of cloud features with respect to the Earth and how those positions change over time as an observer (the ISS in this case) passes over the storm. The photographic images will be used to demonstrate that pseudo-spectroscopy can be used to measure the cloud altitudes to sufficient precision so that, when combined with other remote-sensing data, an accurate determination of the intensity of hurricane or cyclone can be made. Marrow: Today a 51S crewmember completed breath and ambient air sample collections for the Marrow investigation, which looks at the effect of microgravity on bone marrow. It is believed that microgravity, like long-duration bed rest on Earth, has a negative effect on the bone marrow and the blood cells that are produced in the bone marrow. Rodent Research 9 (RR-9): Today the crew completed an audit of the Rodent Research -9 hardware and supplies. The RR-9 investigation was successfully completed and returned on SpaceX-12 last week. The RR-9 experiment studies how microgravity affects the immune systems, muscles and bones of rodents during extended stays aboard the ISS. After approximately 30 days aboard the ISS, the mice will be returned to Earth where scientists on the ground will study how their time in space has affected various tissues, including brain, muscle, heart, joint, the eyes and the immune system. Multi-Omics-Mouse Closeout The crew performed Multi-Omics closeout activities by removing the Mouse Habitat Units from the Cell Biology Experiment Facility (CBEF), cleaning and taking photos of the glove box, and reconfiguring the video cables between the Video Compression and Recording Unit 2 (VRU2) and the CBEF. Manufacturing Device (MD) Operations: The crew removed and replaced the MD feedstock canister, extruder, and print tray. The Manufacturing Device – Additive Manufacturing Facility (AMF) enables the production of components on the ISS for both NASA and commercial objectives. Parts, entire experiments, and tools can be created on demand utilizing the AMF that is installed into an Express Rack locker location. The AMF is capable of producing parts out of a wide variety of thermopolymers including engineered plastics. N3 Aft Port Intermodule Ventilation (IMV) Fan Inlet Cleaning: The crew cleaned this location to remove Foreign Object Debris (FOD) from IMV fan inlets and silencers. Simplified Aid for EVA Rescue (SAFER) Training: In preparation for the upcoming EVAs in October, two US crewmembers were scheduled to perform virtual reality (VR) training simulating emergency recovery using SAFER. In the event a crew member becomes untethered while conducting an EVA, SAFER can be used to safely maneuver for recovery. During the first session, there were some configuration issues, but once the configuration issues were resolved there were still some issues with executing the session. Both of todays sessions were deferred until the ground specialists can further review. Advance Resistive Exercise Device (ARED) Upper Rack Cable Kinked: Today, the crew reported a reoccurrence of the ARED Upper Rack cable kinking. No cable damage was reported. The crew straightened the cable and took imagery for ground review. This is the second instance of this cable kinking this week. There are spare cables on-orbit.

It is believed that microgravity, like long-duration bed rest on Earth, has a negative effect on the bone marrow and the blood cells that are produced in the bone marrow. Combustion Integrated Rack (CIR) Configuration for Advanced Combustion via Microgravity Experiments (ACME): The crew configured the CIR optics bench that will be used to support the ACME investigation. Due to the amount of hardware requiring installation, configuration activities took a couple of days this week to complete. The ACME investigation is a set of five independent studies of gaseous flames to be conducted in the CIR. ACMEs primary goal is to improved fuel efficiency and reduced pollutant production in practical combustion on Earth. Its secondary goal is to improve spacecraft fire prevention through innovative research focused on materials flammability. Sarcolab-3: Today a USOS subject ingressed the Muscle Atrophy Research & Exercise System (MARES) chair, located in the Columbus module, while a Russian operator collected ultrasound images of the subjects right leg during exercise activities. This completed the third and final day of the ankle configuration exercises, which were performed by three different USOS and Russian crewmembers. Later today, the MARES hardware was re-configured to support tomorrows knee configuration exercises. The data collected for Sarcolab-3 will be compared to pre and post-flight measurements to assess the impact of hypothesized microgravity induced muscle loss. Myotendinous and Neuromuscular Adaptation to Long-term Spaceflight (Sarcolab) investigates the adaptation and deterioration of the soleus (calf muscle) where it joins the Achilles tendon, which links it to the heel and carries loads from the entire body. Muscle fiber samples are taken from crew members before and after flight, and analyzed for changes in structural and chemical properties. MRI and ultrasound tests and electrode stimulation are conducted to help assess muscle and tendon changes caused by microgravity exposure. Multi-Omics-Mouse Consolidation: Following the successful completion and return of the Multi-Omics investigation last week, the crew completed item consolidation tasks and returned the Cell Biology Experiment Facility (CBEF) back to its nominal configuration. EVA Preparation: In preparation for the upcoming EVAs, the crew completed Enhanced Caution and Warning System (EWCS) training and EMU battery charging. S-Band String 2 Troubleshooting: Yesterday, the ground team swapped S-Band string 1 to string 2 to gain confidence in its performance. On August 6, 2017, String 2 S-Band/UHF Audio Interface (AUAI)-1P showed intermittent functionality after an AUAI Passive Built-In Test (PBIT) fault indication. Space to Ground (S/G) audio on channels 1 and 2 became unusable.Functionality was recovered by switching to S-band string 1. Since the event, multiple attempts to duplicate the signature have been unsuccessful.The plan is to remain on string 2 until the schedule USOS EVAs in early October.

Space Headaches: The daily questionnaire for the ESA Space Headaches investigation was completed by a 52S crewmember. The Space Headaches investigation collects information that may help in the development of methods to alleviate associated symptoms and improvement in the well-being and performance of crewmembers in space. Headaches during space flight can negatively affect mental and physical capacities of crewmembers that can influence performance during a space mission. Marrow: Today the crew successfully collected the breath and ambient air samples that were not able to be completed yesterday due to an issue with the collection hardware. The Marrow investigation looks at the effect of microgravity on bone marrow. It is believed that microgravity, like long-duration bed rest on Earth, has a negative effect on the bone marrow and the blood cells that are produced in the bone marrow. Human Research Program (HRP) Collections (Biochemical Profile, Repository): Today a 51S crewmember completed the urine sample collections that began yesterday in support of the Biochemical Profile and Repository experiments. With operator assistance, the subject also conducted blood sample collections and the samples were processed for double spin operations using the Refrigerated Centrifuge prior to being placed in the Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI). The Biochemical Profile experiment tests blood and urine samples are obtained from astronauts before, during, and after spaceflight. Specific proteins and chemicals in the samples are used as biomarkers, or indicators of health. Post-flight analysis yields a database of samples and test results, which scientists can use to study the effects of spaceflight on the body. Repositoryis a storage bank used to maintain biological specimens over extended periods of time and under well-controlled conditions. This repository supports scientific discovery that contributes to our fundamental knowledge in the area of human physiological changes and adaptation to a microgravity environment and provides unique opportunities to study longitudinal changes in human physiology spanning many missions. Zero Boil-OFF Tank (ZBOT) Hardware Setup: The crew completed the ZBOT hardware configuration in the Microgravity Science Glovebox (MSG) Work Volume that began yesterday. Rocket fuel, spacecraft heating and cooling systems, and sensitive scientific instruments rely on very cold cryogenic fluids. Heat from the environment around cryogenic tanks can cause their pressures to rise, which requires dumping or boiling off fluid to release the excess pressure, or actively cooling the tanks in some way. ZBOT uses an experimental fluid to test active heat removal and forced jet mixing as alternative means for controlling tank pressure for volatile fluids. Meteor Grating Configuration: The crew removed and replaced gratings in the Meteor camera located in the Window Observational Research Facility (WORF) payload volume. The Meteor payload is a visible spectroscopy instrument with the primary purpose of observing meteors in Earth orbit. Meteor uses image analysis to provide information on the physical and chemical properties of the meteoroid dust, such as size, density, and chemical composition. Since the parent comets or asteroids for most of the meteor showers are identified, the study of the meteoroid dust on orbit provides information about the parent comets and asteroids. Space Test Program – H5 Innovative Coatings Experiment (STP-H5 ICE): The crew photographed four ICE material strips on STP-H5. The harsh radiation and extreme temperatures of space can corrode the paint and coatings that protect spacecraft exteriors, potentially damaging a spacecrafts hull. Optical coatings are also important for robotic and human navigators, who would rely on specialized markings to capture or repair spacecraft. The STP-H5 ICE investigation studies new coatings for use on spacecraft in low-Earth orbit, determining their stability after 2 years in space. Combustion Integrated Rack (CIR) Configuration for Advanced Combustion via Microgravity Experiments (ACME): The crew began configuration activities for the CIR optics bench which supports the ACME investigation. Due to the amount of hardware requiring installation, configuration activities will be conducted over the next two days. The ACME investigation is a set of five independent studies of gaseous flames to be conducted in the CIR. ACMEs primary goal is to improved fuel efficiency and reduced pollutant production in practical combustion on Earth. Its secondary goal is to improve spacecraft fire prevention through innovative research focused on materials flammability. Fast Neutron Spectrometer: The crew completed the installation of the Fast Neutron Spectrometer in Node 1. Neutron spectrometers are used to make a wide range of measurements, including studies of a planetary bodys composition and measuring the flux of high-energy neutrons that could be harmful to humans. The Fast Neutron Spectrometer (FNS) investigation studies a new neutron measurement technique that is better suited for the mixed radiation fields found in deep space. Future manned and exploration missions benefit from clearer, more error-free measurement of the neutron flux present in an environment with multiple types of radiation. Sarcolab-3: With USOS operator assistance, a Russian subject ingressed the Muscle Atrophy Research & Exercise System (MARES) chair in the Columbus module and adjusted pads and constraints for the Sarcolab-3 ankle protocol. The operator then collected ultrasound images of the subjects leg. The subject is continuing the Sarcolab protocol. The data collected for Sarcolab-3 will be compared to pre and post flight measurements to assess the impact of hypothesized microgravity induced muscle loss. Myotendinous and Neuromuscular Adaptation to Long-term Spaceflight (Sarcolab) investigates the adaptation and deterioration of the soleus (calf muscle) where it joins the Achilles tendon, which links it to the heel and carries loads from the entire body. Muscle fiber samples are taken from crew members before and after flight, and analyzed for changes in structural and chemical properties. MRI and ultrasound tests and electrode stimulation are conducted to help assess muscle and tendon changes caused by microgravity exposure. EVA Mobility Unit (EMU) Resize: Today the crew will continue activities to prepare for the upcoming EVAs. They will resize EMUS to fit the specific crewmembers that will go outside during those upcoming EVAs. The goals of the EVAs include performing an R&R on the SSRMS Latching End Effector (LEE) A, lubrication of the LEEs, and external camera replacement. Todays Planned […] Read full story.

Dragon SpaceX (SpX)-12 Unberth: Over the weekend, the crew packed critical items and egressed the vehicle in preparation for Dragon departure. Dragon was unberthed from the ISS via ground commanding on Saturday at approximately 5:06 PM CDT. Ground teams then maneuvered the Dragon to an overnight park position. Early Sunday morning at 03:41 AM CDT, Dragon was released, with splashdown occurring roughly five and a half hours later. Multi-Omics-Mouse: On Saturday, the crew transferred the Mouse Habitat Cage Units from the Cell Biology Experiment Facility (CBEF), to the Transportation Cage Units for return on SpaceX-12. Several studies have reported space flight effects on the human immune system, but the relationship between microbiota and immune dysfunction during flight remains unclear. In the Multi-Omics-Mouse investigation, food with and without fructooligosaccharides (FOS) will be used as prebiotics, to determine if they improve the gut environment and immune function. After the flight, researchers will analyze the gut environment (microbiota and metabolites) and immune system of the mice by multi-omics analysis. ADvanced Space Experiment Processor (ADSEP): On Saturday, the Tissue cassette that was inserted into the Space Automated Bio-product Lab (SABL) on Friday, was removed and returned on SpX-12. ADSEP is a thermally controlled facility that accommodates up to three cassette-based experiments that can be independently operated. A collection of experiment cassettes is used to accommodate experiments in cell technology, multiphase fluids, solution chemistry, separation science, microencapsulation, and crystal growth. For CellCult investigations, each cassette contains a rotating filtered bioreactor, a reservoir for fresh media, two peristaltic pumps, a waste reservoir, and up to 6 sample-collection or reagent containers connected by a manifold to the reactor. Cultures can be operated in continuous perfusion, batch fed, static, or sampling modes. The removal of samples and the addition of additives to the reactor volume can be programmed or tele-operated. Lighting Effects: Over the weekend, a 51S crewmember provided sleep log entries for the Lighting Effects investigation. The light bulbs on the ISS are being replaced with a new system designed for improved crew health and wellness. Fluorescent bulbs are being replaced with solid-state light-emitting diodes (LEDs) that have adjustable intensity and color. Investigators will determine if the new lights improve crew circadian rhythms, sleep, and cognitive performance. Results from this investigation also have implications for people on Earth who use electric lights. Space Headaches: Over the weekend and today, a 52S crewmember completed daily questionnaires for the ESA Space Headaches investigation. The Space Headaches investigation collects information that may help in the development of methods to alleviate associated symptoms and improvement in the well-being and performance of crewmembers in space. Headaches during space flight can negatively affect mental and physical capacities of crewmembers that can influence performance during a space mission. Marrow: With operator assistance, a 52S crewmember collected blood samples for the Marrow investigation. The breath and ambient air sample collection was aborted due to an issue with the collection hardware. After resolving the hardware issue, the breath and ambient collection operations was rescheduled for tomorrow. The blood samples were processed in the centrifuge and placed in the Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI). The Marrow investigation looks at the effect of microgravity on bone marrow. It is believed that microgravity, like long-duration bed rest on Earth, has a negative effect on the bone marrow and the blood cells that are produced in the bone marrow. Human Research Program (HRP) Collections (Biochemical Profile, Repository): Today a 51S crewmember performed a series of urine collections in support of the Biochemical Profile and Repository experiments.

Sarcolab-3: Prior to conducting the operations segment of the Sarcolab-3 investigation, the crew completed setup activities for Ultrasound 2. Then, with assistance from a Russian operator, a USOS crewmember ingressed the Muscle Atrophy Research & Exercise System (MARES) chair in the Columbus module and adjusted pads and constraints for the Sarcolab-3 ankle protocol which is ongoing. The operator then collected ultrasound images of the subjects leg. The data collected for Sarcolab-3 will be compared to pre and post flight measurements to assess the impact of hypothesized microgravity induced muscle loss. Myotendinous and Neuromuscular Adaptation to Long-term Spaceflight (Sarcolab) investigates the adaptation and deterioration of the soleus (calf muscle) where it joins the Achilles tendon, which links it to the heel and carries loads from the entire body. Muscle fiber samples are taken from crew members before and after flight, and analyzed for changes in structural and chemical properties. MRI and ultrasound tests and electrode stimulation are conducted to help assess muscle and tendon changes caused by microgravity exposure. Zero Boil-OFF Tank (ZBOT) Hardware Setup: Today the crew configured the majority of the ZBOT hardware in the Microgravity Science Glovebox (MSG) Work Volume and will complete the remaining setup activities tomorrow. The final configuration will be photographed for historical documentation. Rocket fuel, spacecraft heating and cooling systems, and sensitive scientific instruments rely on very cold cryogenic fluids. Heat from the environment around cryogenic tanks can cause their pressures to rise, which requires dumping or boiling off fluid to release the excess pressure, or actively cooling the tanks in some way. ZBOT uses an experimental fluid to test active heat removal and forced jet […] Read full story.
