The Delta IV Heavy rocket makes liftoff in this photo, so named because it uses three boosters, and delta is the third Greek letter. After watching a video of the launch preparations, I was fascinated by how the Air Force managed to move one of the service towers on a track to get it out of the way. It just seemed amazing how something could be sturdy enough to tower hundreds of feet in the air and still be movable.
