SpaceX's Spent Rocket Could Create a Telescopic Moon Show

A spent SpaceX Falcon 9 upper stage is forecast to crash into the sunlit edge of the Moon near Einstein crater on Aug. 5 at about 6:34 UTC, potentially kicking up a visible plume of debris through telescopes. Simulations suggest roughly 12,700 kg of material could eject, with a plume spanning up to 183 km and peaking about 90 seconds after impact, though visibility depends on impact angle, brightness contrast with the Moon, and local weather. Best viewing opportunities are in the U.S. Southeast, and the event could help researchers understand debris impacts for future lunar exploration.
