Lead Increment Scientist's Highlights for the Week Ending January 6, 2012
(Highlights: Week Ending January 6, 2012) -- The Hyperspectral Imager for the Coastal Ocean (HREP-HICO) Experiment Payload has taken 4760 images to date. The most recent HICO images include part of the New Zealand coast, part of Lake Victoria and Wake Atoll in the Pacific Ocean. The experiment analyzes the water clarity, chlorophyll content, water depth and ocean or sea floor composition for naval purposes.

Crew members continue weekly entries for the Behavioral Issues Associated with Isolation and Confinement: Review and Analysis of Astronaut Journals (Journals) experiment. This study, which requires three entries per week, obtains information on behavioral and human issues that are relevant to the design of equipment and procedures and sustained human performance during extended-duration missions. Study results will provide information to help prepare for future space missions and could help to improve the behavioral performance of people living and working under a variety of conditions here on Earth.

Don Pettit completed his first session with Integrated Resistance and Aerobic Training Study (Sprint). This experiment evaluates the use of high intensity, low volume exercise training to minimize loss of muscle, bone and cardiovascular function in station crew members during long-duration missions. Data gathered from the investigation may help scientists develop or enhance aerobic training and resistance protocols that may be used on Earth to aid in muscle, bone and cardiovascular health.

Three crew members completed runs with the Psychomotor Vigilance Self Test (Reaction Self Test). The experiment is a portable five-minute reaction time task that allows crew members to monitor the daily effects of fatigue on performance while aboard the station. It helps crew members to objectively identify when their performance capability is degraded by various fatigue-related conditions that can occur as a result of station operations and time in space.

Andre Kuipers completed his daily questionnaires for the European Space Agency's Space Headaches experiment. The investigation involves obtaining both current in-flight data and retrospective post-flight data via questionnaires to evaluate the prevalence and characteristics of crew members' headaches in microgravity. Space Headaches investigators use this data to assess crew member headache episodes, analyze characteristics of the headaches and provide the basis for developing future countermeasures.

Selectable Optical Diagnostics Instrument -- Diffusion and Soret Coefficient (SODI-DSC) runs are continuing nominally. This European Space Agency experiment will study diffusion in six different liquids over time in the absence of convection induced by the gravity field.
