Will Enceladus finally answer, ‘Are we alone?’ - by ET_Exists
A two-image mosaic of geysers on the south pole of Enceladus imaged by NASA’s Cassini spacecraft and published on February 23, 2010. organic materials, water vapor, carbon dioxide, carbon monoxide, and a mixture of volatile gases within these geysers, whichindicate the presence of life. Not only do the active geysers indicate the presence of an internal ocean, but it’s also indicative of a source of energy within Enceladus.
With the Cassini mission ending in 2017, there are currently no active missions exploring the Saturn system, let alone Enceladus. However, there are several future missions currently under study which could help us further understand Enceladus and whether it can support life. This includes NASA’s, whose science goals include determining if Enceladus has life, how it has life, and also to locate a suitable landing site for a potential surface mission.
While we wait for another spacecraft to re-visit Enceladus, scientists continue to pour over data from the Cassini mission to try and squeeze every last bit of science about Saturn’s icy moon. We know it has an ocean, which indicates the possibility for life, but what kinds of life could be thriving in its oceanic depths? How has it evolved, and is it similar to life on the Earth?
