Functional Immune: Dry saliva collection was performed in support of the Functional Immune investigation. The Functional Immune Alterations, Latent Herpesvirus Reactivation, Physiological Stress and Clinical Incidence Onboard the International Space Station (Functional Immune) investigation analyzes blood and saliva samples to determine the changes taking place in crew members’ immune systems during flight.

ISS Experience: In preparation for capturing an event later this week, the crew reviewed material containing goals of the investigation, guidelines, and an overview of the hardware it uses. The ISS Experience creates a virtual reality film documenting daily life aboard the ISS. The 8 to 10 minute videos created from footage taken during the six-month investigation cover different aspects of crew life, execution of science aboard the station, and the international partnerships involved. The ISS Experience uses a Z-CAM V1 Pro Cinematic Virtual Reality (VR) 360-degree camera with nine 190° fisheye lenses.

Repository: The crew performed sample collections in support of the repository investigation. The NASA Biological Specimen Repository (Repository) investigation is a storage bank that is used to maintain biological specimens over extended periods of time and under well-controlled conditions. This repository supports scientific discovery that contributes to our fundamental knowledge in the area of human physiological changes and adaptation to a microgravity environment and provides unique opportunities to study longitudinal changes in human physiology spanning many missions.

Systems

Environmental Health System (EHS) Microbial Air and Surface Sampling: The crew took surface and air samples for microbial analysis using the Microbial Air Sampler (MAS) and Surface Sample Kit (SSK). These samples will be incubated in Petri dishes, giving medical personnel a gauge of microbial growth in the air and on surfaces of the ISS. The EHS monitors the atmosphere for gaseous contaminants from nonmetallic materials off-gassing, combustion products, and propellants, microbial contaminants from crewmembers and Station activities, water quality, acoustics, and radiation levels.

Change of Command Ceremony: Today, the ISS Crew participated in a Change of Command Ceremony during which Expedition 62 Commander Oleg Skripochka handed over command of the ISS to Expedition 63 Commander Chris Cassidy. Oleg Skripochka, Jessica Meir and Drew Morgan will return to Earth Thursday night/Friday morning on 61S. Undocking is scheduled for 8:53 pm CT Thursday evening with the landing in Kazakhstan scheduled early Friday morning at 12:17 am CT.
