From the Ground Up: Building an Earth Science Satellite (Part 3) Before a satellite is launched into orbit, scientists use instruments on NASA aircraft to calibrate, validate, and refine sensors that are part of current and future satellite payloads. In this video, data systems analyst Eric Fraim explains how an instrument called MASTER (MODIS Airborne ASTER Simulator) is being used to further develop Earth observing satellites. Flying on board NASA’s high-altitude ER-2, MASTER can detect therma

Scientists use computer programs called climate models to understand how our planet is changing. Climate models are simulations, a way for us to understand something that would be difficult to experience in real life. For example, the average person isn’t allowed to drive a race car. However, simulations—like video games—can help you experience what it would be like to zoom around a racetrack.
