This technology is now integral to the JUICE mission to Ganymede and the upcoming Europa Clipper mission to Europa. Dr. Elena Pettinelli of Roma Tre University, a seasoned expert in planetary exploration using ice-penetrating radar, will soon highlight the potential insights these missions could provide during her upcoming presentation at the European Geosciences Union General Assembly EGU24.
Dr. Pettinelli's prior work includes contributing to the discovery of a stable subglacial water body on Mars. She plans to outline the historical and future applications of ice-penetrating radar in space exploration, focusing on how this technology helps map and analyze liquid water reserves.
The application of ice-penetrating radar is anticipated to reveal the depth and composition of sub-surface water on Jupiter's moons. Dr. Pettinelli notes that the radar's efficacy is influenced by the salinity of the ice, which can hinder radar signals. "By analyzing the response of radio waves, we can better understand salt distribution," she mentions. These findings are further verified through lab experiments by her team.
Dr. Pettinelli emphasizes the importance of this research: "Our knowledge of water distribution in the solar system has grown significantly, and it's fascinating to utilize this technology to pinpoint potential water locations," she concludes.
