On September 21, 2014, NASA's Mars Atmosphere and Volatile EvolutioN mission, or MAVEN, went into orbit around the Red Planet. Its goal: to understand how a changing atmosphere transformed Mars from a warm, wet environment in its youth to the desert world that we see today. Building such a mission and sending it to Mars is a hugely complex task, requiring the close coordination of hundreds of individuals around the country. In this video, several of the team members who made the mission possible share their experiences of working on MAVEN.
