719-What A Night(505)

To give you an idea of the celestial traffic in our neighborhood, on a recent clear night, using our 60 inch telescope on Mt. Lemmon, Arizona, my Catalina Sky Survey teammate Hannes Groller posted 20 new objects on the Minor Planet Center's Near Earth Object Confirmation Page. In the future five of these asteroids may become a valuable source of raw materials for Martian colonists.
