Radi-N2 Neutron Field Study (Radi-N2): Wilmore retrieved eight bubble detectors from deployed locations in the US Lab and delivered them to the Russian crew who will process all detectors in the Bubble Reader. The objective of this investigation is to better characterize the ISS neutron environment and define the risk posed to the crewmembers’ health …
Predetermined Debris Avoidance Maneuver (PDAM) for Object #39372: After evaluating the latest tracking information on object #39372 (Yaogan 12 Debris), the Flight Control Team decided to perform a PDAM at 6:20am CST this morning in order to clear the object. Today’s maneuver will not impact the Soyuz 41S 4-orbit rendezvous scheduled for November 23rd. Cell …
Human Research Program (HRP) Saliva Collection: Wilmore performed a salivary collection and inserted the sample into MELFI. These sample collections were in support of participation in the HRP experiments: Biochem Profile, Repository, and Cardio Ox. Zebrafish Muscle Post Operations: Wilmore disassembled the Aquatic Habitat (AQH) from within the Multi-purpose Small Payload Rack (MSPR) Work Volume …
39 Soyuz (39S) Undock and Landing: Expedition 41 Suraev, Wiseman, and Gerst undocked from the ISS today at 6:31pm CST and landed in Kazakhstan northern landing zone at 9:58pm CST. The crew’s return completes 165 days in space with 2,640 orbits of the Earth. The 39S undock began Expedition 42 under the command of Samokutyaev, …
39S Crew Departure Preparations: Wiseman and Gerst continued to pack their personal items in preparation for their return to earth. The packed items will be returned via Soyuz 39, SpaceX-4, and SpaceX-5. In addition, Wiseman and Suraev conducted a test of the Soyuz 39S Motion Control System. The 39S crew is scheduled to undock from …
Muscle Atrophy Resistive Exercise System (MARES) Battery Removal and Replacement (R&R): Wilmore R&Rd the failed MARES battery followed by a battery status check using the A31p Laptop and battery monitoring Crew Guided Procedure. MARES is an ESA physiological research facility that is designed to carry out research on musculoskeletal, biomechanical, and neuromuscular human physiology. The results …
Zebra Fish Muscle: Gerst connected a water bag and a waste bag to the Aquatic Habitat water circulation unit and performed water exchange #7. The Zebra fish muscle experiment asks if the atrophy of muscles under the condition of microgravity also occurs in zebrafish and why their atrophy occurs in the microgravity Cardio Ox: Wilmore, …
TripleLux-B (BIOLAB): Gerst unstowed tools and items needed for the installation of the distribution and cleaning (D&C) cassette of the Biolab Microscope. This activity was performed in preparation of the upcoming TripleLux-B experiment. The objective of Triplelux-B is to further understand the cellular mechanisms underlying the increase in radiation responses, and the impairment of the …
Russian Joint Research (RJR) Surface Sampling: Serova performed air sampling in USOS Segment Modules (Columbus, Japanese Pressurized Module (JPM), Lab, Node 1, 2, and 3). The investigation refines locations and surfaces prone to microbial contamination throughout the ISS, share monitoring technologies and data between NASA and Roscosmos, and provides a scientific basis for decisions about …
Circadian Rhythms: Gerst donned instrumentation to begin the 36 hour Circadian Rhythm experiment which investigates the role of synchronized circadian rhythms, or the “biological clock,” and how it changes during long-duration spaceflight. Researchers hypothesize that a non-24-hour cycle of light and dark affects crewmembers’ circadian clocks. The investigation also addresses the effects of reduced physical …
