International Space Station Testbed for Analog Research

NASA Public Affairs Officer Kelly Humphries interviews Sandra Fletcher, EVA Systems Flight Controller. They discuss the International Space Station Testbed for Analog Research (ISTAR) activity that mimics robotic and remotely controlled activities that may one day be used on a voyage to Mars. The station offers a unique platform to test future exploration systems and operations because it provides a long-duration, zero-gravity space environment and the opportunity to evaluate many factors not available in other analog missions.
