As a planetary scientist and astrobiologist who studies ice grains from Enceladus, I’m interested in whether there is life on this or other icy moons. I also want to understand how scientists like me could detect it.
Saturn has 146 confirmed moons – more than any other planet in the Solar System – but one called Enceladus stands out.
This fall, NASA partnered with the Open University in the U.K., the University of Colorado, Boulder, and the University of Leipzig in Germany to launch a space orbiter to Europa,
If life exists on moons orbiting Saturn and Jupiter, instruments headed there in the fall may just need a tiny ice grain to find it.
Thanks to mass spectrometers, space probes should be able to detect cellular material on individual ice grains.
