  1. Question

    If you werent prepared to the thing that fly in to jupiter this morning, how can you be sure this is not gonna happen to us?

    We can’t be sure; that is why we are conducting the Spaceguard Survey to find and track near Earth asteroids (see impact.arc.nasa.gov and neo.jpl.nasa.gov or Google “NEO” or “Spaceguard”). But of course, Spaceguard is concentrating on objects that come close to the Earth. We are not surveying near-Jupiter space, but near-Earth space. Thus I am not surprised that we did not find the recent Jupiter impactor before it hit.
