New Atlas | High-speed cannon simulates water-delivering asteroid impacts @gizmag | Uploaded April 2018 | Updated October 2024, 1 day ago.
A water-rich impactor collides with a bone-dry pumice target at around 11,200 miles per hour. The target was designed to rupture partway through the experiment in order to capture materials for analysis. This high-speed video (taken at 130,000 frames per second) slows down the action--in real time, the experiment is over in less than a second.
