The BO administration has been on a tear for the US's satellites. Not sure exactly what its all about but it could be that he wants to focus those satellites on their primary mission of nuke detecting as part of his "decrease the stockpile of nukes" plan. Either that or he thinks 2012 is real and he doesn't want people to panic. If its cost cutting then anytime you can get GOV to cut costs that is a good thing but if it leaves the country vulnerable to attack that is a bad thing. But these satellites are supposed to be used to monitor the world's nukes so they need to do that job. Maybe it will get people to put their own damn satellites up and stop piggie backing off of Uncle Sam. But some science will not get done in the mean time. So the question is, which is the bigger threat, giant asteroids or nuclear weapons? Tough call.
