“ESA's Hera Spacecraft Resolves Didymos Binary Asteroid System from 197 Million km Away” — what this page in the network covers. The European Space Agency's Hera spacecraft has achieved a major milestone in planetary defense, resolving its two target asteroids separately for the first time. The spacecraft, currently some 197 million km (122 million miles) from Earth, has confirmed the binary nature of the Didymos system, reve The spacecraft, currently some 197 million km (122 million miles) from Earth, has confirmed the binary nature of the Didymos system, revealing the primary asteroid Didymos and its smaller moonlet Dimorphos as distinct objects.
This achievement underscores Hera's advanced imaging capabilities and marks a critical step in its mission to study the aftermath of NASA's DART impact. By precisely measuring Dimorphos's mass, shape, and orbital changes, Hera will provide essential data to validate kinetic impact as a viable asteroid deflection technique.
