I didn't know what section to throw this in, but are any of you guys worried about the security of our satellites? I guess I noticed just how much of our everyday life has to do with satellites. Cell phones, television, etc.. The way I've seen computer viruses becoming much more sophisticated lately, and it doesn't seem like the government is on the ball when it comes to keeping updated. Maybe I'm just being paranoid.

most satellite use custom OS's, software and hardware. it would not be easy to hack one and impossible for a virus to infect it unless a hacker on the ground had access to the OS and software used. besides, most of the functions accessible from the ground are relay functions with manouvering operations on an isolated system.
