LUMIO – New CubeSat Illuminating Lunar Impacts

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."
