Event Summary

Scientists analyzing images from the United States===NASA's (NASA) United States===Double Asteroid Redirection Test (DART) mission have found the first visual evidence that small asteroids exchange rocks and dust. Images captured by the United States===Double Asteroid Redirection Test (DART) spacecraft moments before it struck Dimorphos revealed faint, fan-shaped streaks across its surface. Researchers, led by Jessica Sunshine of the University of Maryland, College Park, believe these streaks were formed by debris spun off from Dimorphos' binary companion, Didymos, that drifted between the two bodies and landed in slow-motion impacts. This discovery provides the first direct proof of recent material transport in a binary asteroid system and visual confirmation of the YORP effect, where sunlight gradually speeds up asteroid rotation, causing material to break free. The European Space Agency's International===Hera (space mission) mission is scheduled to arrive at the Dimorphos-Didymos system in December 2026 to conduct a detailed post-impact survey.
