Looking inside icy moons

University of California - Davis
Peer-Reviewed Publication

The outer planets of the Solar System are swarmed by ice-wrapped moons. Some of these, such as Saturn’s moon Enceladus, are known to have oceans of liquid water between the ice shell and the rocky core and could be the best places in our solar system to look for extraterrestrial life. A new study sheds light on what could be going on beneath the surface of these worlds.

University at Albany, SUNY
Grant and Award Announcement

Mustafa Aksoy, an associate professor in the University at Albany’s College of Nanotechnology, Science, and Engineering, is part of a large research team that was awarded a two-year, $1.1 million grant to develop radio frequency interference detection and mitigation strategies for future U.S. weather and climate satellites.

Scientists identify strongly cohesive behavior of Chang'e-6's far-side lunar samples

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

A research team led by Prof. QI Shengwen from the Institute of Geology and Geophysics of the Chinese Academy of Sciences (IGGCAS) conducted fixed-funnel and rotating-drum experiments to measure the angle of repose, a key parameter reflecting the flowability of granular materials. The results showed that Chang'e-6 soil has a substantially higher angle of repose than near-side samples, exhibiting flow behavior characteristic of cohesive soils.
