No, it’s not aliens watching you.
In this case, it’s a security company with satellites watching trucks with hazardous materials. According to this article on Space Daily, Satellite Security Systems has developed a system for tracking trucks hauling hazardous-waste or petrochemical products and, if they become targets of terrorists, shutting them down. In fact, this system is so new that they just tested it this month! And, the test was successful, so I’m sure we can see this technology becoming a standard in those industries. Anyone care to speculate on the implecations of that?
