Hera: Final approach to Didymos begins
ESA · Didymos & Dimorphos · expected ~October 20
Hera arrives at Didymos — the asteroid system we punched with DART in 2022 — to survey the crater and measure exactly how much the impact moved Dimorphos. It's the follow-up visit that turns a one-off deflection test into a repeatable planetary-defense technique.
