The webinar focused on how and why they are searching for NEOs, (Near Earth Objects), and the DART mission, launching next month. Where they will impact an asteroid to push it out of its orbit. The TV channel is eye opening with, for me, tonnes of information on forthcoming space crafts sent to research asteroids and anything related to asteroids both in space and the ones that have reached earth in our recorded life time. I suppose it helps to be unemployed :).
