ISS Daily Summary Report – 5/19/2017

Posted on May 19, 2017 at 4:00 pm by HQ.
 

Fluid Shifts: A 50S crewmember performed their Flight Day (FD) 180 Fluid Shifts Chibis operations in the Russian Segment. They donned the Lower Body Negative Pressure (LBNP/Chibis) device while the operator, with ground support in Moscow, assisted in the medical monitoring.  While the subject was in the LBNP and experiencing the negative pressure (pulling the fluid feetward), the USOS crewmember took measurements for Cerebral and Cochlear Fluid Pressure (CCFP), a Distortion Product Otoacoustic Emission (DPOAE) test, Optical Coherence Tomography (OCT), and a Tonometry examination.  Fluid Shifts is a joint NASA-Russian experiment that investigates the causes for severe and lasting physical changes to astronaut’s eyes. Because the headward fluid shift is a hypothesized contributor to these changes, reversing this fluid shift with a lower body negative pressure device is investigated as a possible intervention. Results from this study may help to develop preventative measures against lasting changes in vision and eye damage.

NeuroMapping: The crew set up the Neuromapping hardware and executed testing in both a “strapped in” and “free floating” body configuration. During the test, the crew completed three Behavioral Assessments: mental rotation, sensorimotor adaptation, and motor-cognitive dual tasking. The NeuroMapping investigation studies whether long-duration spaceflight causes changes to the brain, including brain structure and function, motor control, and multi-tasking abilities. It also measures how long it would take for the brain and body to recover from possible changes. Previous research and anecdotal evidence from astronauts suggests movement control and cognition can be affected in microgravity. The investigation performs structural and functional magnetic resonance brain imaging (MRI and fMRI) to assess changes that occur after spending months on the ISS.

Pressurized Mating Adapter (PMA) 3 Operations: Following this week’s operations, the crew restowed hardware and installed the PMA retention net to keep the Androgynous Peripheral Assembly System (APAS) hatch operational envelope clear of stowage. The crew then closed the PMA 3 hatch.

Extravehicular Mobility Unit (EMU) Operations: Following last week’s EVA #42, the crew performed suit maintenance including scrubbing and iodination of EMU and Airlock cooling water loops. A water sample was taken for subsequent conductivity testing which was also completed today.

Control Moment Gyroscope (CMG) – Ground controllers successfully completed the five year CMG gimbal maintenance on CMG3 and CMG4.   The gimbal maintenance is a 360-degree rotation of the inner gimbals to redistribute the lubricant amongst the gear teeth and to change the wear pattern of the CMG torquer gear train.

ISS Daily Summary Report – 5/22/2017

Posted on May 22, 2017 at 4:00 pm by HQ.

External (EXT) Multiplexer/Demultiplexer (MDM)-1 Failure: On Saturday EXT MDM-1 experienced an anomaly. Attempts to recover the MDM remotely were unsuccessful.  Ground Teams configured EXT MDM-2 as primary and set up systems for the next worse failure per established Flight Rules. An IMMT was held Sunday and directed Team 4 to assess the feasibility of performing an Extravehicular Activity (EVA) to remove and replace (R&R) the failed unit. Team 4 recommended an EVA tomorrow, May 23rd.  Today, the crew prepared for the EVA by configuring and auditing EVA Tools, reviewing procedures, performing an Extravehicular Mobility Unit (EMU) Water Recharge, and configuring the Airlock.

Mobile Servicing System (MSS) Operations: Yesterday Robotics Ground Controllers powered up the MSS and maneuvered the Space Station Remote Manipulator System (SSRMS) to perform a video and imagery survey of the Latching End Effector B (LEE-B) snare cables using the P1 Upper Outboard (UPOB) External High Definition Camera (EHDC).  Once the survey was completed the Ground Controllers maneuvered the SSRMS to a park position.  The plan was to walk the SSRMS off Mobile Base System (MBS) Power Data Grapple Fixture 4 (PDGF4) onto the Node 2 PDGF but it was decided to delay this until after the External Multiplexer/Demultiplexer 1 (EXT-MDM 1) EVA.

Radiation Dosimetry Inside ISS-Neutron (RaDI-N): After retrieving the eight Space Bubble Detectors from the Russian crew, the USOS crew deployed the detectors in Node 3 for the Radi-N2 experiment. The Canadian Space Agency’s RaDI-N investigation uses the bubble detectors to measure neutron radiation levels in the ISS.

Grip Commissioning:  The crew deployed Grip hardware in the Columbus module central aisle.  With support from a second crew member, they attached a chair on a seat track and the first crewmember performed commissioning tasks in the seated configuration. The Grip investigation tests how the nervous system takes into account the forces due to gravity and inertia when manipulating objects. Results may provide insight into potential hazards for astronauts as they manipulate objects in different gravitational environments, support design and control of haptic interfaces to be used in challenging environments such as space, and provide information about motor control that will be useful for the evaluation and rehabilitation of impaired upper limb control in patients with neurological diseases.

ISS Daily Summary Report – 5/23/2017

Posted on May 23, 2017 at 4:00 pm by HQ.

External (EXT) Multiplexer/Demultiplexer (MDM)-1 R&R Extravehicular Activity (EVA):  With IV support from Thomas Pesquet, today Peggy Whitson (EV1) and Jack Fischer (EV2) performed a 2 hour 46 minute EVA to Remove & Replace (R&R) the EXT MDM-1 that failed on Saturday, May 20th. While Whitson performed the EXT MDM R&R, Fischer installed the Lab Nadir External Wireless Communications (EWC) Antennas that were deferred from the last EVA.

Solar Array Battery 3A1 Temperatures – On 5/22/17, Battery 3A1 average temperatures peaked above 25°C for three concurrent orbits due to high solar beta, with a maximum average temperature peak of 25.6°C.  Per Flight Rule, ground controllers terminated the use of the battery string by turning the Battery Charge Discharge Unit (BCDU) 3A1 converter off and commanding the Fault Isolator (FI) open.  There is no impact to downstream loads in this configuration

ISS Daily Summary Report – 5/24/2017

Posted on May 24, 2017 at 4:00 pm by HQ.

OsteoOmics:  The crew fixated BioCells in Biocell Habitat 1 inserted the sample into the Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI).  Crewmembers experience bone loss in orbit stemming from the lack of gravity acting on their bones. OsteoOmics investigates the molecular mechanisms that dictate this bone loss by examining osteoblasts, which form bone, and osteoclasts, which dissolve bone.  Improved understanding of these mechanisms could lead to more effective countermeasures to prevent bone loss during space missions and in a wide range of disorders on Earth. This may lead to better preventative care or therapeutic treatments for people suffering bone loss as a result of bone diseases like osteopenia and osteoporosis, or for patients on prolonged bed rest.

NanoRack Cubesat Deployer (NRCSD) #12: The crew brought the JEM (Japanese Experiment Module) Airlock (JEMAL) Slide Table (ST) into the ISS and replaced the NRCSD #11 Quad deployers with the NRCSD #12 deployers.  The ST was then retracted into the JEMAL which was depressurized and vented.  These activities are in preparation for the planned deployment of CubeSats from the NRCSD #12 over the next two days.

Grip Commissioning:  As part of the ongoing commissioning for the Grip investigation hardware, a crewmember performed tasks in a supine position.  Grip tests how the nervous system takes into account the forces due to gravity and inertia when manipulating objects.  Results from this investigation may provide insight into potential hazards for astronauts as they manipulate objects in different gravitational environments, support design and control of haptic interfaces to be used in challenging environments such as space, and provide information about motor control that will be useful for the evaluation and rehabilitation of impaired upper limb control in patients with neurological diseases. 

Fine Motor Skills: The crew completed a series of interactive tasks during a session of FMS which studies how fine motor skills are effected by long-term microgravity exposure, different phases of microgravity adaptation, and sensorimotor recovery after returning to Earth gravity. The goal of the investigation is to determine how fine motor performance in microgravity trends/varies 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 trends/varies before and after gravitational transitions, including periods of early flight adaptation and very early/near immediate post-flight periods.

On-Board Training (OBT) Dragon Rendezvous Review: The crew performed proficiency training on the Dragon mission profile, rendezvous crew procedures, and crew interfaces for monitoring and commanding the vehicle. This training is in preparation for planned SpaceX-11 launch on June 1 and berthing to ISS on June 4.

ISS Daily Summary Report – 5/25/2017

Posted on May 25, 2017 at 4:00 pm by HQ.

Grasp Commissioning:  To complete commissioning for the Grasp investigation hardware, Pesquet performed tasks in a seated position. Grasp is intended to provide insight into how the central nervous system integrates information from different sensory modalities encoded in different reference frames to coordinate movements of the hand with objects in the environment.  Performed on the ISS, in conjunction with a series of experiments performed on the ground, Grasp explores the interaction between all of the various sensory cues. 

NanoRack Cubesat Deployer (NRCSD) #12 Deploy:  A total of 17 cubesats will be deployed from NRCSD #12. Nine CubeSats were successfully deployed today. The remaining 8 will be deployed tonight and tomorrow. All 17 are from the QB50 constellation of CubeSats that are provided by countries around the world. The constellation aims to study the upper reaches of Earth’s atmosphere over a period of 1 to 2 years. The QB50 satellites conduct coordinated measurements of the thermosphere, a poorly studied and previously inaccessible zone of the atmosphere. The project monitors different gaseous molecules and electrical properties of the thermosphere to better understand space weather and its long term trends.

OsteoOmics:  A crewmember will fixate BioCells in two Biocell Habitats today and then inserted the samples into the Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI).  This completes the fourth and final week of OsteoOmics operations.  Crewmembers experience bone loss in orbit, stemming from the lack of gravity acting on their bones. OsteoOmics investigates the molecular mechanisms that dictate this bone loss by examining osteoblasts, which form bone, and osteoclasts, which dissolve bone.  Improved understanding of these mechanisms could lead to more effective countermeasures to prevent bone loss during space missions and in a wide range of disorders on Earth. This may lead to better preventative care or therapeutic treatments for people suffering bone loss as a result of bone diseases like osteopenia and osteoporosis, or for patients on prolonged bed rest.

Body Measures: Today a 50S subject performed the Body Measures Flight Day 184 session. The crewmember, with assistance from a trained operator, collected Body Measures data after configuring still and video cameras. NASA is collecting in-flight anthropometric data to assess the impact of physical body shape and size changes on suit sizing.  Still and video imagery is captured and a tape measure is used to measure segmental length, height, depth, and circumference data for all body segments (chest, waist, hip, arms, legs, etc.) from astronauts before, during and after their flight missions.

Robotics On-Board Trainer (RoBOT): The crew performed a session of this training during which they completed a 30 meter approach, two Capture Point hold runs and 2 meter runs. This activity was in preparation for SpX-11 capture currently scheduled for June 4.

Mobile Servicing System (MSS) Operations: Yesterday evening Robotics Ground Controllers powered up the MSS and walked the Space Station Robotic Manipulator System (SSRMS) from Mobile Base System (MBS) Power and Data Grapple Fixture (PDGF) 4 to Node2 PDGF. They then translated the Mobile Transporter (MT) from work site (WS) 6 to WS4. MSS is now in configuration for the SpX-11 Crew Offset Grapples tomorrow.

Remote Power Control Module (RPCM) N21B4A_B Trip: Remote Power Controller (RPC) 2 on RPCM N21B4A_B tripped overnight. The RPC supplies power to the Node 2 Starboard Audio Terminal Unit (ATU) 1.  An alternate ATU on the port side of Node 2 is still available for voice, caution and warning tones if needed.  Preliminary review of telemetry did not indicate an overcurrent condition. Today, ground teams attempted to reclose the RPC without success. Teams are continuing to assess their forward plan.

ISS Daily Summary Report – 5/26/2017

Posted on May 26, 2017 at 4:00 pm by HQ.

NanoRack Cubesat Deployer (NRCSD) #12 Cubesat Deploys:  The remaining 8 of 17 NRCSD #12 CubeSats were successfully deployed from the ISS today. All are a subset of the QB50 constellation of CubeSats provided by countries from around the world. The constellation studies the upper reaches of the Earth’s atmosphere over a period of 1 to 2 years. The QB50 satellites conduct coordinated measurements of the thermosphere, a poorly studied and previously inaccessible zone of the atmosphere. The project monitors different gaseous molecules and electrical properties of the thermosphere to better understand space weather and its long term trends.

NanoRacks Module-55:  The crew swapped samples in the NanoRacks Module 55 which is mounted on the front of NanoRacks Platform-1 in the JEM. This investigation researches why bacteria are more virulent and grow more rapidly in space.  NanoRacks Module 55, also known as NanoRacks – National Design Challenge – Centaurus High School – The Effects of Simulated Gravity on Bacterial Lag Phase in a Microgravity Environment (NanoRacks-NDC-CHS-Bacterial Lag Phase), studies the bacterial lag phase, a delay period before the start of exponential growth, which is much shorter in microgravity than it is on Earth. The experiment uses a centrifuge to simulate gravity, comparing microgravity and simulated-gravity Escherichia coli (E. coli) cultures to determine whether microgravity itself causes changes in bacterial growth.

Electrostatic Levitation Furnace (ELF): The crew replaced the ELF Ultraviolet Lamp bulb and set up the ELF gas supply hose and gas bottle. The ELF is an experimental facility designed to levitate, melt and solidify materials by containerless 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.

Soyuz 49 (49S) Nominal Descent Drill: The 49S Crew performed a nominal Soyuz Descent Drill in preparation for their return to earth next week.  Soyuz undock is scheduled for June 2, 2017 at 5:48 AM CDT with landing occurring at 9:10 AM CDT.

Extravehicular Mobility Unit (EMU) Suit Maintenance: The crew completed routine maintenance on EMUs 3006 and 3008 including a loop scrub, iodination and a post-loop scrub water sample.  Following these activities, EMUs 3006 and 3008 were removed and stowed in the Crewlock and EMUs 3003 and 3010 were installed onto the Equipment Lock EMU Don/Doff Assembly.

On-Board Training (OBT)/Mobile Servicing System (MSS) Operations: Robotics Ground Controllers powered up the MSS in the Hot Backup Configuration and maneuvered the Space Station Remote Manipulator System (SSRMS) into position over the Permanent Multipurpose Module (PMM) Flight Releasable Grapple Fixture (FRGF) for the start of the SpX-11 Offset Grapples Practice session. Crew members Whitson and Fisher then practiced maneuvering the SSRMS into the grapple envelope of the PMM FRGF. They performed this several times, then performed a final run during which Controllers safed the SSRMS to simulate a failure. The crew recovered by switching from the Cupola Robotic Workstation (RWS) to the Lab RWS and backing the SSRMS away. Following the training session, Controllers maneuvered the SSRMS to the SpX-11 rendezvous park position.

Remote Power Control Module (RPCM) N21B4A_B Trip Status: RPC 2 on RPCM N21B4A_B tripped Thursday night. This RPC powers the Node 2 Audio Terminal Unit (ATU) 1_ Starboard.  Node 2 ATU-2_Port is still available for caution and warning tones and audio functionality and is connected (via patch panel) to the starboard Crew Quarters.  Review of the 50Hz data did not show any indication of an overcurrent. Ground controllers were able to execute the FET Controller Hybrid (FCH) troubleshooting in an attempt to recover the RPC. The first re-closure attempt was unsuccessful indicating a FCH failure. Approximately an hour after the troubleshooting was attempted, the RPC closed and then re-opened 40 seconds later. Teams believe that this is a new failure signature of the FCH issue and are working a re-closure attempt today. Ground teams will review this new FCH failure signature.

ISS Daily Summary Report – 5/29/2017

Posted on May 29, 2017 at 4:00 pm by HQ.

Cardio Ox Ultrasound:  A 50S crewmember completed their Flight Day (FD) 180 ultrasound, blood pressure and Electrocardiogram (ECG) measurements for the Cardio Ox investigation.  With scanning assistance from a Crew Medical Officer (CMO) and ground remote guidance specialists, the crew donned ECG electrodes and marked the Carotid and Brachial arteries for scanning.  By collecting ultrasound and ECG data along with blood and urine samples scientists will attempt to determine whether biological markers of oxidative and inflammatory stress are elevated during and after space flight and whether this results in an increased, long-term risk of atherosclerosis in astronauts.

Vascular Echo: A crewmember performed Vascular Echo resting ultrasound and blood pressure measurements. With assistance from a ground remote guidance team, he scanned his neck, thigh and heart. This Canadian Space Agency (CSA) investigation examines changes in blood vessels and the heart while crew members are in space, then follow their recovery on return to Earth. Results could provide insight into potential countermeasures to help maintain crew member health and quality of life for everyone.

Radiation Dosimetry Inside ISS-Neutron (RaDI-N) Retrieval: The crew retrieved all 8 of the Space Bubble Detectors that were deployed last week in the Node 3 module for the RaDI-N experiment and handed them to the Russian crew to be processed in the Bubble Reader. This CSA investigation measures neutron radiation levels while onboard the ISS.  Bubble detectors are used as neutron monitors designed to only detect neutrons and ignore all other radiation.

Manufacturing Device (MD): The Manufacturing Device failed to complete the 12 hour print of a Radiation Environment Monitoring shield on Friday and during a second attempt yesterday. The REM shield was to be installed in the BEAM during ingress later this week. The Made-In-Space team is assessing the anomaly.  The MD – Additive Manufacturing Facility (AMF) enables the production of components on the ISS to meet both NASA and commercial objectives.  Parts, entire experiments, and tools can be created on demand utilizing the AMF.  The AMF is capable of producing parts using a wide variety of thermopolymers, including engineered plastics.

Extravehicular Mobility Unit (EMU) Suit Maintenance: Following last week’s removal of EMUs 3006 and 3008 and installation of EMUs 3003 and 3010 on the Equipment Lock EMU Don/Doff Assembly the crew performed routine maintenance on EMU 3003 and 3010 including a loop scrub, iodination and conductivity tests.

Soyuz 49 (49S) Nominal Descent Drill: The 49S Crew performed a nominal Soyuz Descent Drill in preparation for their return to earth.  Soyuz undock is scheduled for June 2, 2017 at 5:48 AM CDT with landing occurring at 9:10 AM CDT.

Commercial Orbital Transport Services (COTS) UHF Communication Unit (CUCU) Checkout:  In preparation for the upcoming SpaceX-11 capture and berthing planned for June 4th, the crew coordinated with ground teams to activate the CUCU System and perform a Crew Command Panel (CCP) checkout. CUCU provides a command and telemetry communications link between ISS and Dragon during free flight operations in the vicinity of ISS.

ISS Daily Summary Report – 5/30/2017

Posted on May 30, 2017 at 4:00 pm by HQ.

Human Research Program (HRP): A 49S crewmember collected Return minus 15 days (R-15) blood and urine samples for Vascular Echo, Biochem Profile, and Marrow investigations as well as air samples for Marrow and ultrasound measurements for Vascular Echo.

    The Vascular Echo investigation examines changes in blood vessels and the heart while crew members are in space, then follows their recovery when they return to Earth. The results could provide insight into potential countermeasures to help maintain crewmembers’ health.  A new, powerful, relatively easy to use ultrasound system will be used that could provide new opportunities for experimentation aboard the ISS.  In the field of telemedicine on Earth, such tele-operated scanners could result in progress in the medical management of persons in remote areas.
    The Biochem Profile experiment tests blood and urine samples 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 in their study of the effects of spaceflight on the body.
    The Marrow investigation identifies the effect of microgravity on bone marrow.  It is believed that microgravity, like long-duration bed rest on Earth, has a negative effect on blood cell production in bone marrow.

Group Combustion Module (GCM):  The crew exchanged fuel supply syringes and reinstalled the Combustion Chamber back in MSPR Work Volume for continued GCM operations. The Group Combustion investigation tests combustion changes of fuel sprays as flames spread across a cloud of droplets. In the MSPR, fuels are arranged randomly on thin-fiber lattice points and the flame and droplet positions and temperature distribution are measured as the flame spreads.  Microgravity blocks convection, which on Earth would quickly disperse the droplets and combustion products before such measurements could be made.

NanoRack Cubesat Deployer (NRCSD) #12: The crew brought the JEM (Japanese Experiment Module) Airlock (JEMAL) Slide Table (ST) into the JEM and remove the NRCSD #12 Quad Deployer from the Multi-Purpose Experiment Platform (MPEP). This activity is in preparation for the installation of Japanese Small Satellite Orbital Deployer #7 (J-SSOD #7) installation on the ST planned for June 16, 2017.

Veg-03: The crew completed the final harvest of leaves for crew consumption from Chinese Cabbage growing in the Veggie facility. They also placed VEG-03 plant samples, swabs, and water syringes into a Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI) for return to the ground and cleaned the Veggie facility.  The goal of Veg-03 is to further demonstrate the proof of concept for the Veggie plant growth chamber and planting pillows. Future long-duration missions into the solar system will require a fresh food supply to supplement crew diets, which entails growing crops in space. Previous investigations focused on improving productivity in controlled environments but the limited quarters of the space shuttle and ISS made it difficult to conduct large-scale crop production tests. Veg-03 expands on previous validation tests of the Veggie hardware to grow cabbage, lettuce and other fresh vegetables. Tests determine which types of microorganisms are present in space-grown cabbage, providing baseline data for future crop-growing efforts. Behavioral health surveys assess the impact of growing plants on crew morale and mood.

On-Board Training (OBT) Health Maintenance System (HMS):  FE-2 performed refresher training for the HMS which is a subsystem of Crew Health Care System (CHeCS) that monitors crew health, responds to crew illness and/or injury, and provides preventive health care. These lessons provide a refresher course and cover some of the equipment and procedures that are taught in the Crew Medical Officer (CMO) classes.

ISS Daily Summary Report – 5/31/2017

Posted on May 31, 2017 at 4:00 pm by HQ.

Passive Thermal Testbed:  The crew removed the Electro-Wetting Drawer and replaced it with the Heat Pipe Drawer for the Passive Thermal Testbed investigation. The PTT demonstrates the in-space performance of three advanced thermal management technologies, an important step toward improving these technologies for use on future space exploration missions. The investigation leverages the fluid cooling capabilities of another ISS experiment, the Phase Change Heat eXchanger (PCHX).  It includes a suite of advanced heat pipe based technology devices: (1) a new hybrid wick, warm biased integrated reservoir, variable conductance heat pipe that can passively adjust to changing thermal conditions, allowing efficient energy transport in warm conditions and power conservation in cold conditions; (2) a high conductivity plate for heat acquisition and heat sharing; and (3) an early concept electro-wetting heat pipe that has the potential to increase heat transport by orders of magnitude over existing heat pipes.

Cardiac Stem Cells:  The crew set up Life Science hardware in the Microgravity Science Glovebox (MSG) to support Cardiac Stem Cell operations to be conducted after arrival of samples and media on the SpaceX-11 vehicle.  Cardiac Stem Cells investigates how microgravity affects stem cells and the factors that govern stem cell activity, including physical and molecular changes.  Spaceflight is known to affect cardiac function and structure, but the biological basis for this is not clearly understood. This investigation helps clarify the role of stem cells in cardiac biology and tissue regeneration. In addition, this research could support confirmation of the hypothesis that microgravity accelerates the aging process.

NanoRacks Module-55:  Following completion of all sample runs for the investigation, the crew removed and stowed NanoRacks Module-55 hardware from the front of NanoRacks Platform-1 in the Japanese Experiment Module (JEM).  The NanoRacks Module-55 investigation supports research into why bacteria are more virulent in space and grow more rapidly there.  It focuses on the bacterial lag phase, the period prior to the beginning of exponential bacterial growth, which is much shorter in microgravity than it is on Earth.  The experiment uses a centrifuge to simulate gravity, allowing a comparison of microgravity and simulated-gravity Escherichia coli (E. coli) cultures to determine whether microgravity itself causes changes in bacterial growth.

Bigelow Expandable Activity Module (BEAM):  The crew ingressed the BEAM and installed a Radiation Environment Monitor (REM) shield onto a REM sensor.  This shield is a 3.3 mm thick component produced by the 3D printer on the ISS.  BEAM is an experimental expandable module attached to the ISS.  Expandable modules weigh less and take up less room on a rocket than a traditional module, while allowing additional space for living and working. They provide protection from solar and cosmic radiation, space debris, and other contaminants. Crews traveling to the moon, Mars, asteroids, or other destinations could possibly use them as habitable structures.

Fine Motor Skills: The crew completed a series of interactive tasks during a FMS session which studies how the fine motor skills are effected by long-term microgravity exposure, different phases of microgravity adaptation, and sensorimotor recovery after returning to Earth gravity. The goal of the investigation is to determine how fine motor performance in microgravity trends/varies 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 trends/varies before and after gravitational transitions, including periods of early flight adaptation and very early/near immediate post-flight periods.

Dose Tracker:  The crew completed a weekly medication tracking entry in the Dose Tracker application.  Dose Tracker documents the medication usage of crewmembers before and during their missions by capturing data regarding medication use during spaceflight, including side effect qualities, frequencies and severities. The investigation is expected to provide anecdotal evidence of medication effectiveness during flight and any unusual side effects experienced. It is also expected that specific, near-real-time questioning about symptom relief and side effects will provide the data required to establish whether spaceflight-associated alterations in pharmacokinetics or pharmacodynamics is occurring during missions.

On-Board Training (OBT) Robotics On-Board Trainer (RoBOT): SpX-11 is scheduled to launch Thursday, June 1 and berth to the ISS on June 4.  In preparation for capture and berthing, the crew performed a session of this training during which they completed 3 capture point hold runs to practice free drift timing, malfunction response and nominal rate approaches.

Emergency Roles & Responsibilities Review: In preparation for departure of the 49S crew this Friday, the 50S crew reviewed individual duties during an emergency response. Topics covered included crew accountability, escape vehicle readiness, ISS Commander responsibilities and communication and coordination with the various Control Centers.

Crew Quarters (CQ) Cleaning: In preparation for his departure from the ISS this Friday, FE-5 cleaned his CQ including intake and exhaust ducts, fans and airflow sensors.

ISS Daily Summary Report – 6/01/2017

Posted on June 1, 2017 at 4:00 pm by HQ.

SpaceX (SpX)-11 Launch: SpX-11 is scheduled to launch today at 4:55 pm CDT. Pending a successful launch, capture and berthing are planned for Sunday, June 4th at 9:00am CDT.

Rodent Research-5 (RR-5):  The crew unpacked, installed and configured four Animal Habitats and configured the Microgravity Science Glovebox (MSG) for RR-5 operations to be performed after arrival of rodents and additional hardware and materials on SpaceX-11. The Ground team successfully completed a software checkout of all the Habitats.

DOSIS 3D:  The crew de-installed DOSIS 3D passive detectors and handed them over to a Russian crewmember for packing for return on Soyuz 49S.  Data from the various active and passive radiation detectors are used in the determination of the radiation field parameters absorbed doses and dose equivalents inside the ISS. A concise three dimensional (3D) dose distribution map of all the segments of the ISS will be developed based on this data and data from JAXA and NASA monitoring devices.

Matiss:  The crew de-installed the four Matiss Sample Holders from the Columbus module for return on 49S.  The MATISS experiment investigates the antibacterial properties of materials in space to see if future spacecraft could be made easier to clean. The experiment aims to understand the mechanisms of attachment of biofilms in microgravity conditions. MATISS objectives include simplification of decontamination operations to save crew time and validation of innovative surfaces for use in future spacecraft.

ISS Change of Command: In preparation for 49S departure on Friday, Peggy Whitson handed over command of the ISS to Fyodor Yurchikhin. During this event, the entire crew discussed with Mission Control Center (MCC)-Houston and MCC-Moscow Flight Control their roles and responsibilities for the timeframe between the Change of Command event and tomorrow’s 49S departure.  Following the Change of Command, the new Commander’s Soyuz crew became prime for emergencies.
