Back of an Astronaut in the center.
At the end of six and a half hours, astronauts Steve Bowen and Al Drew completed some relocation of station exterior tools and rails, and moved the 800-pound broken ammonia pump. It was quite a list of tasks to accomplish. They were assisted with use of the robotic Canadarm operated by astronaut Mike Barratt and Commander Scott Kelly. Kelly is the twin brother of Commander Mike Kelly who will be commanding STS134, and who is also the husband of Congresswoman Gabriella Giffords who was wounded in the head in the infamous Arizona shooting recently.
And they pay them to do this!?!
Steve Bowen has another record. Not only is he the first astronaut to do back-to-back missions, he is also the first astronaut to do spacewalks on consecutive missions. He replaced astronaut Tim Kopra, who was injured in a bicycle accident before the launch.
