Let the conspiracy theories run wild. For years, planetary scientists and astronomers have benefited from an unofficial arrangement with the U.S. Military. With access to data from the Defense Support Program satellite network (part of the Pentagon's early-warning system), they've had the ability to better study incoming meteorites -- but no longer.
While the breakup popped up on Space.com just last week, Nature.com reports that the relationship came to an effective end at the beginning of 2009. Interestingly enough, this roughly corresponds to the activation of the United States' latest $10 billion fleet of new-generation surveillance satellites.
The United States has used infrared satellites to monitor the Earth since 1970. If anyone launches a missile or detonates a nuclear weapon, theses satellites pick up on the heat signature. Likewise, if anything enters the Earth's atmosphere and burns a path through the sky, it'll note that as well.
Experts tend to believe that the deployment of new satellite technology is the reason scientists have been cut out of this particular information source. The government simply doesn't want details on the new gear and its capabilities leaking out. After all, the satellite network's primary purpose is to aid national security.
As sensible as that sounds, however, there's still no official reason for the arrangement's end. As such, by all means, dream up with some truly harebrained possibilities on your own. Is the U.S. government covering up the steady stream of incoming alien ships, which leave laden with probed human captives and choice cuts of beef? Are Pentagon nerds using the satellites to spy on sorority houses "Animal House" style?
