SpaceX (SpX)-6 Capture and Berthing: The Dragon vehicle was captured at 5:55 AM CDT today followed by nominal berthing, vestibule outfitting and Common Berthing Mechanism (CBM) Control Panel Assembly (CPA) removal. Tomorrow, the crew will ingress the vehicle and begin unpacking cargo.
Fine Motor Skills: Kelly and Kornienko performed their Flight Day (FD) 20 Fine Motor Skills session. In this experiment crew members perform a series of interactive tasks on a touchscreen tablet. The investigation 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 is to answer how fine motor performance in microgravity trends/varies over the duration of a six-month and year-long space missions; how fine motor performance on orbit compares with that of a closely matched participant on Earth; and how performance trends/varies before and after gravitational transitions, including the periods of early flight adaptation and very early/near immediate post-flight periods.
Rodent Research-2 (RR-2) (Center for the Advancement of Science in Space (CASIS)): Virts and Kelly reviewed RR Animal transfer reference materials in preparation for transferring the animals from the transporter to the Habitat. This experiment monitors the effects of the space environment on musculoskeletal and neurological systems of mice as model organisms of human health and disease. Living in microgravity results in significant and rapid effects on the physiology of mice that mimic the process of aging and some diseases in humans on Earth, including muscle atrophy and the loss of bone mineral density. This project will help scientists to discover new molecular targets that can facilitate the development of novel therapeutics for the treatment of muscle and bone-related diseases. Long-duration exposure to microgravity will also induce changes in gene expression, protein synthesis, metabolism, and eye structure/morphology that will be identifiable as a series of assessable biomarkers for tracking the onset and progression of disease. In addition, biological specimens from this experiment will be shared with other researchers seeking to understand the effects of various environmental stressors on human health and fitness.
Double cold bag unpack: Virts reviewed double coldbag unpacking procedures in preparation for transferring early destow cold stowage utilization that arrived on Spx-6.
Osteo-4: Cristoforetti reviewed on board training materials in preparation for transfer and experiment configuration tasks associated with the Osteo-4 hardware that arrived on Spx-6. Osteo-4 studies the effects of microgravity on the function of osteocytes, which are the most common cells in bone. These cells reside within the mineralized bone and can sense mechanical forces, or the lack of them, but researchers do not know how. Osteo-4 allows scientists to analyze changes in the physical appearance and genetic expression of mouse bone cells in microgravity.
The Effect of Long-Term Microgravity Exposure on Cardiac Autonomic Function (Biological Rhythms 48): Kelly completed the second 24-hour segment of the 48-hour monitoring session, removed the digital walk Holter electrocardiogram (ECG) body sensors and saved the data for downlink. Biological Rhythms 48 hours studies the effects of long-term microgravity exposure on heart function by analyzing an astronaut’s electrocardiogram for 48 hours. While ISS keeps 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.
Circadian Rhythms: Cristoforetti completed the 6th of six 36-hour Circadian Rhythms sessions, doffed the monitoring equipment and downloaded the data. The objective of the experiment is to obtain a better understanding of alterations in circadian rhythms in humans during long-duration spaceflight. Such knowledge will provide insight into the adaptations of the human autonomic nervous system in space over time, and has significant practical implications by helping to improve physical exercise, rest and work shifts as well as fostering adequate workplace illumination in the sense of occupational healthcare in future space missions. The Circadian Rhythms will be measured by monitoring the body’s core temperature. During the first, mid and last session, the armband system will also be used.
Commercial Generic Bioprocessing Apparatus (CGBA) Compact Flash (CF) card swap: Kelly installed new CF cards in CGBA-4. Upon completion of the card swap, the CF card performance can be characterized as compared to the CGBA-6 which previously had a CF card swap.
