The deployment of the interstage on the Saturn V rockets used for the moon landings. From Apollo VI. The author is NASA, and the picture is in public domain.
It's a beautiful shot, I just wish it wasn't so grainy at high resolution, If it weren't it would have been my desktop right here right now. But still worthy, I believe, of a good 9/10 in anybody's book.
Just FYI, this is the separator ring between the first and second stages. My dad was director of test for the second stage, so I had the privilege (once) to see it being transported to a ship which took it to Cape Canaveral, FL.
Too bad I couldn't have sat on top of the rocket with a trusty tripod and camera - though it's probably better for my health. Great image - though I enjoyed the thumbnail more than the high-res.
thnx for sharing degaboh
