Microgravity Science Glovebox (MSG) Cleanup and Reconfiguration: Kelly completed the second and final MSG cleanup session following the completion of RR2. Following cleanup, Padalka installed the Observation Analysis of Smectic Islands in Space (OASIS) experiment hardware. The sample installation, final connections and camera checkout will be scheduled on another day. OASIS studies the unique behavior of liquid crystals in microgravity, including their overall motion and the merging of crystal layers known as smectic islands. Liquid crystals are used for display screens in televisions and clocks and they also occur in soaps and cell membranes. 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. Ocular Health: Kelly and Kornienko executed their Flight Day 90 Ocular Health activities today including Optical Coherence Tomography (OCT) to measure retinal thickness, volume, and retinal nerve fiber layer and Fundoscope measurements to collect retinal images. For these operations, Padalka assisted Kelly and Kelly was the Crew Medical Officer for Kornienko. 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. Radiation Dosimetry Inside ISS-Neutrons (RADI-N): Kelly retrieved the eight RADI-N detectors from their deployed locations and handed them over to Kornienko for downlink of the data. The objective of this investigation is to better characterize the ISS neutron environment and define the risk posed to the crewmembers’ health and provide the data necessary to develop advanced protective measures for future space flight. ISS Reboost: The ISS performed a reboost at 5:59 am CDT today using 58P thrusters. This reboost was added to the timeline as the result of 43S Soyuz launch date moving from July 24 to July 22. A second reboost is planned for July 10 to finalize setup for 43S Soyuz 4-orbit launch. Delta-V was 0.5 meters/second and burn duration was 4 minutes, 8 seconds. Today’s Planned Activities All activities were completed unless otherwise noted.
