(Highlights: Week of November 7, 2011)
Lead Increment Scientist's Highlights for the Week of November 7, 2011
-- As of Nov. 10, the Alpha Magnetic Spectrometer - 02 (AMS-02
) has recorded data for eight billion particle events. The AMS-02 uses the unique environment of space to advance knowledge of the universe and lead to the understanding of the universe's origin by searching for antimatter, dark matter and measuring cosmic rays.
The Hyperspectral Imager for the Coastal Ocean (HREP-HICO
) Experiment Payload has taken 4,451 images to-date. The most recent HICO images include the Florida coast near Choctawhatchee Bay and Panama City, Coral Bay in Australia and part of Lake Erie. The experiment analyzes the water clarity, chlorophyll content, water depth and ocean or sea floor composition for naval purposes.
Satoshi Furukawa completed building the Communications and Global Positioning Satellite on Nov. 9 for the LEGO® Bricks
To date, Furukawa has completed a total of 12 LEGO brick activities.
These LEGO activities allow crewmembers to demonstrate the difference between building LEGO bricks on Earth vs. in microgravity. They are designed to promote student interest in science, technology, engineering and mathematics (STEM).
Through Nov. 9, nearly 30,000 images have been received for reviewing and cataloging for the Crew Earth Observation (CEO
) experiment. Recent images include: Hawaii in sun glint; Pakistan; Great Barrier Reef, Queensland; Tashkent, Uzbekistan; Tarawa Atoll, Kiribati; and Mexico City, Mexico. For this experiment, station crew members photograph natural and human-made changes on Earth. These images provide researchers with key data to better understand the planet.
Furukawa made successful contact with Rehabilitationszentrum, a rehabilitation hospital in Switzerland, as part of the International Space Station HAM Radio experiment (ISS HAM Radio
) on Nov. 9. Nine children asked 13 questions. Local newspapers covered the event, and the audience consisted of about 50 people, the kids and hospital nurses. Mike Fossum made contact with the Donald P. Sutherland School in New York on Nov. 10. More than 200 attendees were in the audience and four television stations were on hand. By utilizing ham radios, this experiment gets students interested in space exploration by allowing them to talk directly with the crews living and working aboard the space station. To date, crew members have made 116 contacts in 2011 and 682 project events since ISS HAM inception.
Fossum and Furukawa completed sessions with the Biomechanical Analysis of Treadmill Exercise on the International Space Station (Treadmill Kinematics
) experiment. It is the first rigorous investigation to quantify the biomechanics of treadmill exercise conditions during long duration spaceflight. Exercise prescriptions are developed under the assumption that walking and running in microgravity have the same training effects as during normal gravity. However, if locomotion kinematics and kinetics differ between microgravity and normal gravity, understanding these mechanisms allows the development of appropriate exercise prescriptions to increase exercise benefits to crew health and well-being.
Furukawa completed a final session of the Cardiac Atrophy and Diastolic Dysfunction During and After Long Duration Spaceflight: Functional Consequences for Orthostatic Intolerance, Exercise Capability and Risk for Cardiac Arrhythmias (Integrated Cardiovascular).
This experiment determines how much cardiac atrophy, or decrease in heart muscle, occurs during spaceflight and how fast it develops, whether this atrophy causes problems with the heart's pumping or electrical function, and how both the atrophy and any associated changes develop.
In conjunction with Integrated Cardiovascular, Furukawa completed a final session with Vascular Echography (Vessel Imaging
). This European Space Agency experiment evaluates the changes in thickness and compliance of blood vessel wall properties and cross sectional areas of crew members during and after long-term exposure to microgravity.
