NASA ISS On-Orbit Status 23 December 2014

Today: Neuromapping: The crew supported operations to complete objectives of the NeuroMapping Neurocognitive Test.
After connecting a control pad to the HRF laptop, Virts launched the NeuroMapping application and completed the Mental Rotation I Test, the Sensorimotor Adaptation Test, the Dual Task Test while tethered, and the Mental Rotation II Test while free-floating. Wilmore took photographs of the subject Virts completing the tasks. The Neuromapping experiment studies whether long-duration spaceflight causes any changes to the brain, including brain structure and function, motor control, and multi-tasking; as well as measuring how long it takes for the brain and body to recover from those possible changes. Previous research and anecdotal evidence from crewmembers returning from a long-duration spaceflight suggests that movement control and cognition are affected in microgravity. The NeuroMapping investigation utilizes structural and functional magnetic resonance brain imaging (MRI and FMRI) to assess any changes to crewmembers after a six-month mission on the International Space Station.

ISS SERVIR (“to serve” in Spanish) Environmental Research and Visualization System (ISERV): Wilmore will retrieve the hard drive plugged into the ISERV laptop and connect it to an SSC for imagery downlink. ISERV is an automated system designed to acquire images of the Earth’s surface from the International Space Station (ISS). It is primarily a means to gain experience and expertise in automated data acquisition from the ISS, although it is expected to provide useful images for use in disaster monitoring and assessment, and environmental decision making.

Bone and Muscle Check: Cristofotetti will collect Saliva and urine samples to support Bone and Muscle Check. Salivary Markers of Metabolic Changes during Space Missions (Check-Saliva) tests crewmembers’ saliva, blood, and urine before, during and after spaceflight to study whether saliva tests can serve as reliable health monitors. Microgravity reduces bone and muscle mass, which is related to changes in certain substances in the bloodstream and urine. Some of these changes can also be detected in saliva samples. Tests using Check-Saliva can validate whether saliva and/or urine can be used as simple, non-invasive tools to monitor crewmembers’ bone and muscle status during a space mission

Skin-B: Cristoforetti conducted her second Skin-B data collection using the Tewameter probe to measure the skin barrier function; the Visioscan Camera to measure skin surface topography; and the Corneometer probe to measure skin hydration. The Skin-B experiment will improve understanding of skin aging, which is slow on Earth but very much accelerated in space. This will also provide insights into the aging process in other (similar) bodily tissues in general. The data could help in determining impact on astronauts on future missions to the Moon and Mars for example where environmental conditions are more challenging.

Dragon cargo operations: Virts and Christoforetti continued cargo operations to prepare hardware for return on Dragon.

Nitrogen/Oxygen Recharge System (NORS) Hardware Search: Wilmore performed a search for a bag of NORS hardware had been displaced and successfully found the hardware. The NORS system when installed replaces the Space Shuttle capability to deliver high pressure nitrogen and oxygen to replenish the ISS High Pressure Gas Tanks (HPGTs).
