IMPACT SUCCESS! Watch from #DARTMIssion’s DRACO Camera, as the vending machine-sized spacecraft successfully collides with asteroid Dimorphos, which is the size of a football stadium and poses no threat to Earth. pic.twitter.com/7bXipPkjWD

“…As for the details of that impact, we’ll have to wait. The best images we’ll get are from an Italian Cubesat called LICIACube that has been trailing DART since the two separated a few weeks ago. LICIACube will be about 50 km from the point of impact and will get even closer over the three minutes after impact before passing behind Dimorphos. But it will take some time to transmit images to Earth—possibly a day or more for processing and release.
So, the first images are likely to come from ground observatories, which are looking for brightening caused by the debris plume spreading from the point of impact. When asked how much ground-based hardware was dedicated to watching for the plume, Cristina Thomas of Northern Arizona University said, “I don’t know, but there’s a lot of them—it’s very exciting to have lost count.” Nancy Chabot of APL said the count was up to three dozen, and they’ll be joined by the Hubble and Webb Space Telescopes. Some of those images are likely to show up online by tomorrow. https://arstechnica.com/science/2022/09/dart-goes-silent-after-hitting-an-asteroid/
