When I was watching the show I was wondering why they did not put a second probe right behind the first to observe the impact.

And when I went looking for more information about DART it turns out they did. the LICIACube. very cool.

So now the question is why was this not mentioned in the nasa show(perhaps I missed it) and why have I not heard anything about LICIACube from anywhere else(perhaps I missed this as well).

did LICIACube fail and every one is being quiet about it?
