HII Transfer Vehicle (HTV)5 Launch: Today’s scheduled launch of HTV5 from Tanegashima, Japan was scrubbed due to weather. The next launch attempt will be Wednesday, August 19 at 6:50 am CDT with capture on Monday, August 24 at 5:55 am CDT. Human Research Program (HRP) Operations: Kelly and Kornienko performed Day 1 of 3 for their Flight Day (FD) 150 Ocular Health session and their second Pilot-T session. Kelly completed his FD 146 Fine Motor Skills session and is scheduled for his first of three weekly Journal sessions. Lindgren (FD 27) and Kornienko (FD 142) completed Cognition. Ocular Health: Kelly and Kornienko performed vision tests followed by vision questionnaires. The crew then took blood pressure measurements, and with Padalka as the Crew Medical Officer (CMO), performed tonometry measurements. The Ocular Health protocol calls for a systematic gathering of physiological data to characterize the risk of microgravity-induced visual impairment/intracranial pressure in ISS crewmembers. Fine Motor Skills is the first fine motor skills study to measure long-term microgravity exposure, different phases of microgravity adaptation, and sensorimotor recovery after returning to Earth gravity. The goal of Fine Motor Skills 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. The goal of the Pilot-T experiment is to improve methods and develop equipment to assess and predict crewmember performance reliability during the execution of complex operator tasks (piloting a space vehicle and controlling transport and robotic equipment on the surface of a spacecraft) during various stages of long-term spaceflight. Journals obtains information on behavioral and human issues that are relevant to the design of equipment and procedures and sustained human performance during extended-duration missions. Individualized Real-Time Neurocognitive Assessment Toolkit for Space Flight Fatigue (Cognition) is a battery of tests that measure how spaceflight-related physical changes, such as microgravity and lack of sleep, can affect cognitive performance. Observation Analysis of Smectic Islands in Space (OASIS) Hard Drive Exchange: Kornienko swapped the Hard Drives for the OASIS experiment. Following the swap, an island test was conducted by ground controllers. The removed hard drive was stowed for return on a later flight. OASIS studies the unique behavior of liquid crystals in microgravity, including their overall motion and the merging of crystal layers known as smectic islands. The experiment allows detailed studies of the behavior of these structures, and how microgravity affects their unique ability to act like both a liquid and a solid crystal. Plant Rotation: Yui began Plant Rotation Run 4 today which will continue through August 26 with observation by JAXA controllers. He prepared the samples and initiated the sample incubation period in the Cell Biology Experiment Facility (CBEF). Many species of climbing plants grow upward in a spiraling shape, a process known as circumnutation. Plant organs, such as stems, leaves, and roots also grow in a spiraling, helical shape. This spiraling process can take many forms, including very tight loops and broad curves. The Plant Rotation experiment verifies the hypothesis that this type of plant growth requires gravity. Biological Rhythms 48 Hour: Lindgren started his 48-hour data collection, donning electrodes and wearing a Holter Electrocardiogram (ECG) and Actiwatch Spectrum to monitor and log circadian rhythms. Biological Rhythms studies the effects of long-term microgravity exposure on heart function by analyzing an astronaut’s electrocardiogram for 48 hours. While the ISS follows Greenwich Mean Time (GMT), it remains unknown whether a separate biological rhythm is imposed on long-term flight crews. To study this astronauts wear an Actiwatch sleep monitor for 96 hours and a Holter electrocardiograph for 48 hours in the middle of that sequence. Robonaut: Lindgren viewed an On-Board Training (OBT) video, and encountered communication issues with the robot. The team was able to resolve the communication problems and proceeded with further Robonaut troubleshooting of recent signatures indicating power being removed from the robot’s main processors. Lindgren removed the torso cover and swapped out the power supply card on the computer chassis. After applying power to the robot, the new power supply showed a green LED indicating good power to the supply, but the red fault LED was lit and no power was flowing to the rest of the chassis. Due to time constraints, further troubleshooting could not be done. Robonaut is a project under a Space Act agreement with General Motors, which plans to use Robonaut-related technology in future vehicle safety systems and manufacturing applications. Robonaut helps to advance development of robotic assistant and manufacturing technologies that improve worker health and safety inside factories. As part of the demonstration, Robonaut is also involved in several education and public outreach activities, connecting robotics and the space program to students and the general public on Earth. Node 3 (N3) Inter-Module Ventilation (IMV) Cleaning: Yui cleaned the N3 Deck Forward IMV fan. This activity is expected to restore normal ventilation air flow in the Cupola and reduce noise produced by the IMV fan. On-Board Training (OBT) Robotics On-Board Trainer (ROBoT): In preparation for HTV5 capture and berthing, the 3 USOS crew members completed another session of this training. In addition to self-study, they practiced a 30 meter approach and 2 Capture Point (CP)-hold runs. Internal Thermal Control System (ITCS) Sampling: On Saturday, Lindgren collected an ITCS fluid sample from the Lab. Its Ortho-phthalaldehyde (OPA) biocide concentration was nominal. Today, Kelly collected an ITCS fluid sample from the JEM. Its OPA concentration was also nominal. Extravehicular Mobility Unit (EMU) Water Conductivity Test: Today, Kelly tested the conductivity of water samples obtained from EMUs 3003 and 3010. Today’s Planned Activities All activities were completed unless otherwise noted.
