ESA’s Hera Mission Arrives at Didymos, First Human‑Shifted Asteroid

ESA’s Hera asteroid detective, accompanied by CubeSats Milani and Juventas, has reached the Didymos double‑asteroid system after a two‑year journey. The mission marks the first time a Solar System object has had its orbit altered by human intervention. Upon arrival, Hera will conduct a series of observations while the CubeSats detach to perform close‑up examinations of Dimorphos, the smaller companion. The event is highlighted in the new episode of ‘The Incredible Adventures of the Hera Mission,’ which explains the spacecraft’s objectives and the CubeSats’ departure for detailed study. The mission provides critical data on asteroid composition, structure, and the effectiveness of kinetic‑impact techniques for planetary defense.
