Scientists have verified that a method to look for cellular life on Europa, an ice-covered moon of Jupiter, just might work. The technique could be put to the test in the 2030s, when NASA’s Europa Clipper probe is due to make multiple flybys over the Jovian moon.
The technique involves analyzing grains of ice that scientists expect one of the instruments on Europa Clipper — known as the Surface Dust Analyzer, or SUDA — to pick up as it flies through plumes of frozen water rising up from Europa’s surface.
“It’s astonishing how the analysis of these tiny ice grains may tell us whether or not there is life on an icy moon. At least we now know that SUDA has these capabilities,” University of Washington planetary scientist Fabian Klenner told GeekWire in an email. Klenner is the lead author of a research paper about the process, published today in the open-access journal Science Advances.
