Kind: launch · Impact: low

## In brief

- ESA's Hera spacecraft is visiting the Dimorphos-Didymos asteroid system.
- The mission is examining the aftermath of NASA's 2022 DART impact.
- Hera is taking a close look at the asteroid's moonlet.

## Why it matters

Hera's close-up survey of the impact site gives planetary scientists direct data on how a kinetic impactor changed a binary asteroid, which informs future planetary defense planning.
