Nasa has asked scientists to consider ways that a Europa mission could search for evidence of alien life in the plumes of water vapour that apparently blast into space from Europa's south polar region. These plumes, which Nasa's Hubble Space Telescope spotted in December 2012, provide a possible way to sample Europa's ocean of liquid water, which is buried beneath the moon's icy shell, researchers said.

As currently envisioned, Clipper would travel to Jupiter orbit, then make 45 flybys of Europa over 3.5 years, at altitudes ranging from 25 km to 2,700 km. The $2.1 billion mission would study Europa's subsurface ocean, giving researchers a better understanding of the water's depth, salinity and other characteristics. Nasa also wants to add plume sampling to the Europa mission's task list, if possible. During a Europa plume workshop at the Ames Research Center in Silicon Valley earlier this week, Nasa science chief John Grunsfeld urged attendees to 'think outside the box' and come up with feasible ways to study the moon's plumes. Researchers would want to analyse bits of Europa material in well-equipped labs here on Earth, but bringing samples back is likely beyond the scope of the flyby mission currently under consideration. However, it may be possible to detect biomolecules onsite, using gear aboard a Clipper-like probe, researchers said. Spotting a set of amino acids that all display the same chirality, or handedness, in plume material would be strong evidence of Europan life, astrobiologist Chris McKay, of Nasa Ames, said at the workshop. Collecting enough plume material to perform such analyses will likely prove extremely challenging, 'SPACE.com' reported. It may require flying so low and so slowly that it makes more sense to send a lander down to the Europa surface through the plume, said astrobiologist Kevin Hand of Nasa's Jet Propulsion Laboratory in Pasadena, California. However, first the spacecraft should be able to find the water vapour when it gets to Europa. At the moment, the plume remains unconfirmed; scientists have pointed Hubble at Europa repeatedly since the initial 2012 detection, but have come up empty in attempts to spot it again. So, if the plume exists, it is apparently sporadic or episodic, not continuous like the powerhouse geysers that erupt from the south pole of Saturn's icy moon Enceladus, researchers said.
