[*]Asteroids: It is believed that an asteroid strike eliminated the dinosaurs on the Earth. One of the benefits of space exploration is that we know about the thousands of asteroids and we can also be vigilant about their "drifts". May be we could prevent 'dinosaurian death of mankind', if and when an asteroid is positioned to repeat history. If it happens, it would be because of the knowledge which is the direct benefit of space exploration.

WASHINGTON — NASA's Hubble Space Telescope has observed a mysterious X-shaped debris pattern and trailing streamers of dust that suggest a head-on collision between two asteroids. Astronomers have long thought the asteroid belt is being ground down through collisions, but such a smashup has never been seen before. Image from Hubble:
