Ocular Health: Padalka performed his Flight Day (FD) 30 fundoscopy, with assistance from Virts as his CMO and ground remote guiders. The fundoscope is utilized to image the fundus (interior surface of the eye including the retina, optic disc, macula, and fovea). 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. Researchers believe that the measurement of visual, vascular and central nervous system changes over the course of this experiment and during the subsequent post-flight recovery will assist in the development of countermeasures, clinical monitoring strategies, and clinical practice guidelines. Rodent Research-2 Center for the Advancement of Science in Space (RR-2 CASIS): Kelly completed a fixative swap on the samples collected during yesterday’s RR-2 operations. Following the swap, the samples in the new fixative were inserted into MELFI. Mycological Evaluation of Crew Exposure to ISS Ambient Air (MYCO) Familiarization: Kelly reviewed the procedure prior to his first MYCO collection scheduled for tomorrow. The MYCO experiment evaluates the risk of microorganisms’ via inhalation and adhesion to the skin to determine which fungi act as allergens on the ISS. Nanoparticles and Osteoporosis and Kubik Closeout: Cristoforetti removed the last 6 of the 8 Nanoparticles and Osteoporosis Experiment Containers (ECs) and stowed them in Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI). She comleted a data download, stowed the Kubik and packed Kubik-3 for return on SpX-6. Nanoparticles based countermeasures for Treatment of microgravity induced osteoporosis (Nanoparticles and Osteoporosis) studies how microgravity changes the metabolic environment of bone leading to site-specific alterations in bone remodeling. This study uses strontium containing hydroxyapatite nanoparticles (nHAP-Sr) as a countermeasure to prevent osteoporosis induced by microgravity during space flight. The in vitro biological effect of nHAP-Sr will be evaluated on differentiated human osteoblasts and osteoclasts and during their differentiation process, varying incubation time and dose-dependence in simulated microgravity and during space flight. Nematode Muscle: Cristoforetti retrieved the nematode samples from the Cell Biology Experiment Facility (CBEF) and performed sample fixation using the Chemical Fixation Apparatus. The samples were then inserted into MELFI. The Alterations of C. elegans muscle fibers by microgravity (Nematode Muscles), aims to clarify how and why these changes take place in microgravity. Studying worms exposed to both microgravity, and gravity-like conditions in a centrifuge, could help scientists understand the molecular mechanisms responsible for muscle atrophy and other spaceflight-induced changes. Advanced Resistance Exercise Device (ARED) Maintenance: Virts performed this regularly scheduled quarterly maintenance. He greased the Vibration Isolation System (VIS) rails, rollers and upper stop catch plates and inspected the X-rotation dashpots. The task was completed nominally and no problems were reported. Robotics Operations: Today the Robotics Ground Controllers powered up the Mobile Servicing System (MSS) and released the Dragon Flight Releasable Grapple Fixture (FRGF). They then walked SSRMS off Node 2 Power Data Grapple Fixture (PDGF) onto the Mobile Base System (MBS) PDGF 1. After completing the walk off, the Robotics Ground Controllers manoeuvred the SSRMS to the Mobile Transported (MT) translation position for tomorrow (GMT113) translation from Worksite #4 to Worksite #7 in preparation of the Robotic Refueling Mission (RRM) transfer ops next week. MSS performance today was nominal. Today’s Planned Activities All activities were completed unless otherwise noted.
