ESA's Hera reaches Didymos to study DART's 2022 impact

ESA's Hera spacecraft has arrived at the Didymos asteroid system, positioning 25–30 km from Dimorphos to study the aftermath of NASA's 2022 DART impact. Hera will examine Dimorphos's altered shape and debris distribution, providing key data to assess whether kinetic impactors can effectively defend Earth from asteroid threats.
