LUMIO is a newly approved CubeSat mission to observe meteoroid impacts on the lunar farside. This week, the ESA approved the next stage of the Lunar Meteoroid Impacts Observer (LUMIO) CubeSat mission, meaning it could be ready for launch as early as 2027. In 2023, Postdoctoral Research Associate Aleksandra Sokołowska was selected to be a member of the LUMIO Science Team. She shared her excitement for the project, saying "Being a part of this mission in its early stages has been incredibly fun and rewarding because members of our Science Team come from many different countries, work collaboratively, and the areas of expertise are very diverse. This final mission approval means that the journey continues."

For their AP environmental science and biology field trip, Barrington High School students visited the Blackstone River to learn about Rhode Island's history of pollution. The trip was supported by the RI NASA Space Grant. “We want to get students outside the classroom beyond the textbooks and internet articles they read about,” said Ralph Milliken, Program Director and DEEPS Associate Professor. “So they can understand the interplay on human society and the natural environment.”

Professor Jim Head commented on China's Chang'e-6 Moon-lander samples, saying, "Obtaining dates and compositional information from the many hundreds of fragments sampled by the Chang’e-6 drill and scoop is like a having treasure chest full of critical parts of lunar history, and will very likely revolutionize our view of the entire Moon."
