An oddly colored view of Lake Fitri, Chad was captured for the Crew Earth Observation investigation. The low-light view illustrates a complex climate history for this area of the Sahara offering both the landforms of alternating periods of flooding and desertification.

(Highlights: Week of February 20, 2012) -- Don Pettit completed his third session with Integrated Resistance and Aerobic Training Study (SPRINT). This investigation 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.

Several runs with two different samples were conducted with the Binary Colloidal Alloy Test-6: Phase Separation (BCAT-6-Phase Separation). The goal is to gain unique insights into how gas and liquid phases separate and come together in microgravity. These fundamental studies on the underlying physics of fluids could provide the understanding needed to enable the development of less expensive, longer shelf-life household products, foods and medicines.

Pettit continued flame tests for the Structure and Liftoff In Combustion Experiment (SLICE). SLICE investigates the nature of flames in microgravity. The results from these investigations could lead to improvements in technologies which aim to reduce pollution emissions and improve burning efficiency for a wide variety of industries.

Pettit conducted a test with the Capillary Flow Experiments - 2 (CFE-2). The test was to compare a recent run with one back in January to check for any delayed response in the critical angles of the vane gap vessel. CFE-2 is a suite of fluid physics investigations that study how fluids move up surfaces in microgravity. The results aim to improve current computer models that are used by designers of low gravity fluid systems and may improve fluid transfer systems for water on future spacecraft. On Earth, CFE-2 results are also being considered for improving fluid flow in miniaturized biological devices used for health screening and analysis.

Through Feb. 19, 57,793 images have been received for reviewing and cataloging for the Crew Earth Observation (CEO). For this investigation, station crew members photograph natural and human-made changes on Earth. These images provide researchers with key data to better understand the planet.
