"How much?
Based on the measurements, the team estimated that there was about 220 pounds (100 kilograms) of water in the view of their instruments, which took in the area of the impact crater (about 66 feet or 20 meters across) and the ejecta blanket (about 200 to 260 feet across, or 60 to 80 meters), Colaprete said. That amount of water is roughly the equivalent of a dozen 2-gallon buckets."
