I'd try to establish contact with one of the space stations out there, I mean, they should also have survived... right? However, it will be a long and difficult journey to find NASA's headquarter or something, so I'd first stock up on supplies and probably find a gun of some sort (because you just never know, right? Better safe than sorry).
Also, I'd check the internet for any signs of other survivors before going on my journey.
