Dawn mission data reveals complex surface geology on dwarf planet Ceres (universetoday.com)

• Gravity anomaly at 50 km depth beneath Occator crater indicates brine reservoir
• Bright surface deposits from cryovolcanic eruptions linked to subsurface brines
• Findings support potential for a Ceres sample return mission

"New analysis of NASA's Dawn mission data, presented at EGU26 in Vienna, shows the surface of dwarf planet Ceres is more complex than previously thought. A gravity anomaly at 50 km depth beneath Occator crater indicates a subsurface brine reservoir that may have fueled cryovolcanic eruptions, leaving bright deposits. The findings have implications for Ceres' thermal history and future sample return missions."
