Study suggests individual ice grains ejected from Saturn and Jupiter's moons may contain terrestrial-like life detectable by future missions, like NASA's Europa Clipper.

A study led by the University of Washington indicates that individual ice grains ejected from Saturn and Jupiter's moons might contain enough material to be detected by instruments onboard future missions if extraterrestrial life exists. The study demonstrates that even a tiny fraction of cellular material can be identified by a mass spectrometer onboard a spacecraft, increasing confidence that lifeforms similar to those on Earth could be present on ocean-bearing moons. The upcoming NASA Europa Clipper mission will carry more instruments to explore these icy moons in detail.
