That’s crucial information for mission scientists preparing NASA’s Europa Clipper spacecraft, which will use radar to scan beneath the ice shell to see if Europa’s ocean could be hospitable to life.
The study was led by The University of Texas at Austin, which is also leading the development of Europa Clipper’s ice-penetrating radar instrument.
Knowing what kind of ice Europa’s shell is made of will also help determine the salinity and habitability of its ocean.

According to co-author Donald Blankenship, the research is validation for using the Earth as a model to understand the habitability of Europa.Blankenship is a senior research scientist at UTIG and principal investigator for Europa Clipper’s ice-penetrating radar instrument.
“We can use Earth to evaluate Europa’s habitability, measure the exchange of impurities between the ice and ocean, and figure out where water is in the ice,” he said.Wolfenbarger is currently pursuing a doctoral degree in geophysics at the UT Jackson School and is a graduate student affiliate member of the Europa Clipper science team.
