ARED (Advanced Resistive Exercise Device)
The Advanced Resistive Exercise Device (ARED) uses adjustable resistance piston-driven vacuum cylinders along with a flywheel system to simulate free-weight exercises in normal gravity. Studies have found that without exercises like those possible on the ARED, astronauts could lose up to 15% of their muscle volume, which could be difficult or even impossible to regain back on Earth. ARED's primary goal is to maintain muscle strength and mass in astronauts during long periods in space. (Source: NASA)
Columbus Research Laboratory The Columbus Research Laboratory is a multifunctional pressurized laboratory permanently attached to Node 2 of the ISS. The Columbus laboratory’s flexibility provides room for the researchers on the ground, aided by the station’s crew, to conduct thousands of experiments in life sciences, materials sciences, fluid physics and other research in a weightless environment not possible on Earth.
