"Measuring Europa's Ice Thickness with Impact Crater Images"

Planetary scientists have used physics and images of impact craters to estimate the thickness of the ice shell on Jupiter's moon, Europa. By studying large craters on Europa's surface, researchers concluded that the ice shell is at least 20 kilometers thick, challenging previous estimates of a thin ice layer over a thick ocean. This finding is crucial for understanding the potential for life on Europa, as the ice shell's thickness influences processes within it and the exchange of material between the surface and the ocean.

"Icy Moon Ocean Temperatures Revealed by Ice Thickness"

Scientists are exploring the possibility of warm oceans under icy shells on various Solar System objects, which could potentially support life. Researchers at Cornell University have developed a method to determine the temperature of an icy world's ocean by measuring the thickness of its ice shell and associated properties, known as ice pumping. This method could provide insights into the ocean temperatures of distant worlds without the need for direct exploration. The study has implications for upcoming missions, such as NASA's Europa Clipper, which aims to measure Europa's ice thickness more accurately and potentially uncover clues about the potential for life in these ocean worlds.

Decades of Antarctic Ice Sheet Data Unveiled

A comprehensive dataset on Antarctic ice thickness and bed topography, compiled over the past 60 years by more than 50 institutions, has been released, providing valuable information for predicting future ice loss and sea level rise. The dataset, known as Bedmap3, includes 52 million new data points and 1.9 million kilometers of measurements, doubling the amount of available data. The freely accessible dataset will aid in the development of more accurate models and help policymakers address the impact of Antarctica on rising oceans.
