Ice-penetrating radar, a geophysical tool, has shown capable of identifying liquid water on Earth and beneath Mars South polar cap.Now, this instrument is aboard the JUICE spacecraft and it is on its method to Jupiters icy moon Ganymede and will also be aboard the Europa Clipper spacecraft, which will be released to Europa later this year. Pettinelli, who was part of the team that discovered a subglacial stable body of liquid water on Mars, will trace the historic applications of ice-penetrating radar in planetary expedition before she dives into potential uses of ice-penetrating radar in locating and characterizing liquid water.Scientists hope to utilize ice-penetrating radar to identify the depth and chemistry of water beneath the icy surface of Jovian moons. “Theres much more water than we thought 20 or 30 years ago, and its really fascinating to use this strategy to attempt to understand where the water might be.
