➀ The European Space Agency's Hera spacecraft is en route to the asteroid impacted by NASA's DART mission in 2022. The probe is part of a mission to study the 'kinetic impact' technique for asteroid deflection. ➁ Hera will conduct detailed surveys of the asteroid Dimorphos and perform deep-space technology experiments. ➂ The spacecraft is expected to arrive at the binary asteroid in autumn 2026, providing valuable data for planetary defense.
