(Highlights: week of April 15, 2013) - The Expedition 35 crew completed the Burning and Suppression of Solids (BASS) third test session aboard the International Space Station. BASS examines the burning and extinction characteristics of a variety of fuel samples in microgravity. The investigation will guide strategies for extinguishing accidental fires in space. Results from this investigation contribute to the combustion computational models used in the design of fire detection and suppression systems in microgravity and on Earth.

Canadian Space Agency astronaut Chris Hadfield, Expedition 35 commander, and NASA astronaut Tom Marshburn successfully completed Blood Pressure Regulation (BP Reg) sessions. The experiment is testing a simple in-flight method to predict which crew members are at greatest risk of fainting after returning to Earth. This test may in the future help to identify the astronauts who could benefit from countermeasures before returning to Earth. This method has great potential for astronaut health monitoring during future long-term spaceflights and it also has important implications for testing individuals on Earth, especially the elderly, who are at risk for fainting. The research also will demonstrate in space the feasibility of obtaining a set cardiovascular regulation indicators from the non-invasive measurement of continuous blood pressure.

The test session was completed for the Synchronized Position, Hold, Engage, Reorient, Experimental Satellites-VERTIGO (SPHERES-VERTIGO) investigation. This study uses the SPHERES facility free-flying satellites and is designed to demonstrate and test, in a complex environment, enhanced technologies and techniques related to visual inspection and navigation. This effort incorporates hardware and software that enables multiple SPHERES to construct three-dimensional models of a target object. Additionally, this investigation explores how well the SPHERES free-flyers then perform relative navigation solely by reference to these 3D models.

Human research investigations continued for various crew members including Circadian Rhythms, Repository, Nutrition, Energy, Space Headaches, Reaction Self Test, Dietary Intake Can Predict and Protect Against Changes in Bone Metabolism During Spaceflight and Recovery (Pro K), and the Space Linear Acceleration Mass Measurement Device (SLAMMD).
