First asteroid sightings push Hera’s camera to the limit

Asteroid (18805) Kellyday

ESA’s Hera mission has captured images of asteroids (1126) Otero and (18805) Kellyday. Though distant and faint, the early observations serve as both a successful instrument test and a demonstration of agile spacecraft operations that could prove useful for planetary defence.

Hera is currently travelling through space on its way to a binary asteroid system. In 2022, NASA’s DART spacecraft impacted the asteroid Dimorphos, changing its orbit around the larger asteroid Didymos. Now, Hera is returning to the system to help turn asteroid deflection into a reliable technique for planetary defence.
