How much?
Based on the measurements, the team estimated about 100 kilograms of water in the view of their instruments — the equivalent of about a dozen 2-gallon buckets — in the area of the impact crater (about 80 feet, or 20 meters across) and the ejecta blanket (about 60 to 80 meters across), Colaprete said.
"I'm pretty impressed by the amount of water we saw in our little 20-meter crater," Colaprete said.
