  • Summary

  • In September 2022, a small spacecraft called DART hit the surface of a tiny asteroid moonlet called Dimorphos. That spacecraft was the first test of a planetary defense system, attempting to change an asteroid's orbit in the hope of being able to do so under a real near-Earth threat. The test succeeded, shortening the moonlet's orbit by 32 minutes. Now, a follow-up mission called Hera is on its way to the system, complete with an orbiter and a lander. The European Space Agency plans to observe the impact site and measure any changes to the shape and any craters left behind. Join communications specialist Beth Johnson as she chats with Hera's principal investigator, Patrick Michel, from the Université Côte d'Azur about the mission, the science, and the technology being tested.
