Mars Atmosphere and Volatile EvolutioN Mission (MAVEN) is a space probe designed to study the Martian atmosphere while orbiting Mars. Mission goals include determining how the planet's atmosphere and water, presumed to have once been substantial, were lost over time.

A maven (also mavin) is a trusted expert in a particular field, who seeks to pass knowledge on to others. The word maven comes from Hebrew, meaning "one who understands", based on an accumulation of knowledge.
