Episode Description from the Publisher

Discover how ESA's Hera spacecraft saw the Didymos and Dimorphos asteroids as two separate objects for the first time. Learn why the pair previously looked like a single dot, how the 18 October image from about 1,280 km revealed tiny Dimorphos, and how NASA's 2022 DART impact shortened Dimorphos's orbit by about 33 minutes — and why Hera's close-up study matters for planetary defence.Become a supporter of this podcast: https://www.spreaker.com/podcast/science-made-simple--6610397/support.
