Aside from giant laser beams, can eyes in the sky help save us from asteroid hits?

Canada thinks so, and it has launched a space telescope to track hazardous objects including asteroids, space junk, and satellites.

The Near-Earth Object Surveillance Satellite (NEOSSat) was launched from an Indian rocket this week as the first dedicated space-based sentinel of its kind.

Managed by the Canadian Space Agency (CSA) and Defence Research and Development Canada (DRDC), NEOSSat is about the size of a suitcase and orbits some 500 miles above Earth, circling every 100 minutes.
