The Aerover is a small helium-filled blimp that can be steered and moved up and down within the atmosphere to explore different altitudes. Three propellers are likely to be used to allow this maneuvering. Our first close-up look at Titan will be when the Cassini spacecraft arrives in the Saturn system in 2004. The spacecraft will deploy the Huygens probe to study Titan, gathering data that may lead to a mission after 2010, with the possible use of the Aerover Blimp for further exploration
