ESA title

As part of the world’s first test of asteroid deflection, Hera will perform a detailed post-impact survey of the target asteroid, Dimorphos – the orbiting moonlet of a binary asteroid system known as Didymos. Now that NASA’s DART mission has impacted the moonlet, Hera will turn the grand-scale experiment into a well-understood and repeatable planetary defence technique. Demonstrating new technologies from autonomous navigation around an asteroid to low gravity proximity operations, Hera will be humankind’s first probe to rendezvous with a binary asteroid system and Europe’s flagship Planetary Defender.

Hera Launch: October 2024

Target: Dimorphos

DART impact date: 26 September 2022

Hera rendezvous: October 2026

1081 kg launch mass
