Rosetta is a European Space Agency-led unmanned space mission launched in 2004 intended to study the comet 67 P/Churyumov-Gerasimenko. Rosetta consists of two main elements: the Rosetta space probe and the Philae lander. The probe is named after the Rosetta Stone, as it is hoped the mission will help unlock the secrets of how our solar system looked before planets formed.
Rosetta is an American post-metal band incorporating elements of death metal, drone music, and ambient music creating a sprawling, atmospheric sound similar to Neurosis and Cult of Luna, and coined by some as "space metal". Their debut album, The Galilean Satellites, featured two separate hour-long discs (one of more metal-oriented music, and one of ambiance) that synchronize together.
