Garan conducts CsPINs Experiment Operations

ISS027-E-017840 (28 April 2011) --- NASA astronaut Ron Garan, Expedition 27 flight engineer, supports the Dynamism of Auxin Efflux Facilitators responsible for Gravity-regulated Growth and Development in Cucumber (CsPINs) experiment in the Kibo laboratory of the International Space Station. CsPINs studies the phenomenon of tropism, i.e., the growth or turning movement of a biological organism, usually a plant, in response to an environmental stimulus. Specifically focusing on gravity, the new JAXA life science experiment investigates how plants sense gravity as an environmental signal and use it for governing their morphology and growth orientation.
