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. Repository is 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 spacecraft’s 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. ACME’s 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 body’s 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 subject’s 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. Today’s Planned […]
