The Atlantic’s In Focus photoblog has a spectacular collection of imagery from the 30-year run of the Space Shuttle program at NASA. Next Friday (July 8) marks the final launch of the last Space Shuttle to go into orbit and will mark an end to the entire Space Shuttle program which will have sent 135 flights into Space.

I highly encourage you to click through and check out the NASA archives here.

The photo above shows a rare look inside the shuttle’s external tank as it gets ready for a launch.
