South Korea's Compact Advanced Satellite (CAS) 500-2 successfully launched from Vandenberg Space Force Base in California on a SpaceX Falcon 9 rocket. The satellite entered low-Earth orbit and made first contact with a ground station in Norway. The Korea AeroSpace Administration (KASA) confirmed it is operating normally.
Scientists have discovered that the Southern Ocean releases 40% more carbon dioxide during winter than previously estimated. Using laser satellite data and machine learning, researchers pierced the polar darkness to reveal this hidden emission burst. The findings reshape understanding of the ocean's role in the global carbon cycle.
