Google Earth

Does anyone know of a website with more current satellite images than google earth. I have checked a few different sites, and the most current I can find, is from sometime in Spring 2011.

I know the image date, by the drilling pad placed on a specific location, and the well was completed during fall of 2011. The site I pull up, still only shows the drilling pad, nothing more.

I would now like to see updated shots, as well as current activity from earlier 2013 if possible. A site that charges a fee would be considered also. Even a site with 2012 updates would be nice.
