Jupiter’s icy moon Europa puzzles astrobiologists and sparks the imagination of extraterrestrial life seekers.
It is believed that the moon has a subsurface ocean of liquid water, where life could possibly be similar to microbial life forms on Earth.
The likely presence of liquid water has ignited persisting calls to send a probe there. Currently NASA and ESA plan their own missions to the potentially habitable moon. Europa Clipper mission has just got approved for $30 million in the 2016 NASA budget and ESA’s Jupiter Icy Moon Explorer (JUICE) is scheduled for launch in 2022.
