Interstellar Motivations
From Encyclopedia Superheroica -the Encyclopedia of Superheroes
It is not just invasion by alien armada that threatens the Earth. We also face microbial menaces and even "extinction level events" as the result of interaction with completely inanimate objects.

Astronomical Allies
With such names as "Argus", "Sentry", "Sentinel", "Spaceguard", and "Project Blue Book", there have been countless efforts to protect the citizens of Earth from death from above.
NASA
In 1998 NASA commenced its part of the "Spaceguard" effort, with the goal of discovering and tracking over 90% of the near-Earth objects larger than one kilometer by the end of 2008. An Earth impact by one of these relatively large objects would be expected to have global consequences and, over time scales of a few million years, they present the greatest impact hazard to Earth. Approximately 60% of the estimated 1,000 to 1,200 large near-Earth objects have already been discovered, about 45% since NASA efforts started, and each of the five NASA-supported search facilities continue to improve their performance, so there has been good progress toward eliminating the risk of any large, undetected impactor.
