Russia Plans Mission to Land a Rocket on Jupiter's Ganymede, Only Moon with its Own Magnetic Field --"100-Kilometer-Deep Ocean a Hotspot for Life"
In a video uploaded to YouTube on August 3rd (below), engineers from the Russian space agency, Roscosmos, proposed an orbiter and lander mission to Ganymede. The video suggests a launch could come in the next decade. Although the commentary is in Russian, the video appears to suggest that Ganymede may be as good a candidate or better for life than Europa.
In March of 2015, NASA's Hubble Space Telescope revealed the best evidence yet for an underground saltwater ocean on Ganymede, Jupiter's largest moon. The subterranean ocean is thought to have more water than all the water on Earth's surface. Identifying liquid water is crucial in the search for habitable worlds beyond Earth and for the search for life, as we know it. Video http://bit.ly/2bJvCbZ
