NASA's DART mission reveals insights on binary asteroid system

NASA's DART mission, which collided with the asteroid moonlet Dimorphos in 2022, has revealed new insights into the binary asteroid system Didymos-Dimorphos. Recent studies indicate Dimorphos is significantly younger than Didymos, with ages of less than 300,000 years and 12.5 million years, respectively. The findings enhance understanding of asteroid formation and surface characteristics, aiding future planetary defense efforts, including ESA's Hera mission set for 2026.
