Deflecting asteroids with DART and Hera
Ahead of Asteroid Day on 30 June, we take a look at NASA's DART and ESA's Hera mission. Starting in 2022, these two missions will work together to test how we might one day deflect a potential deadly asteroid. Later on, we interview Andrea Riley, the DART's programme executive and give you our stargazing tip of the month. See acast.com/privacy for privacy and opt-out information.
