The Mars Atmosphere and Volatile Evolution mission (MAVEN) launched on November 18, 2013, and entered orbit around Mars on September 21, 2014. The mission’s goal is to explore the planet’s upper atmosphere, ionosphere, and interactions with the Sun and solar wind. Scientists will use MAVEN data to explore the loss of volatile compounds—such as CO2, N2, and H2O—from the Martian atmosphere to space. Understanding atmospheric loss will give scientists insight into the history of Mars' atmosphere and climate, liquid water, and planetary habitability.
