This is the space shuttle Atlantis, en route to the International Space Station. The first flight of Atlantis was October 3, 1985. This flight will be the last. STS-132 is the 32nd flight for the 25 year old spacecraft. Because of its age – affecting parts for which the original vendor is no longer in business – NASA can no longer ensure the safety of the ground crew when the vehicle is pressurized for take off, much less the flight crew.
The retirement of Atlantis means that only Discovery and Endeavor will remain in the shuttle fleet. This point is nearly moot, as each of those shuttles have only one flight left before NASA shuts down the shuttle program to focus on flights to asteroids and Mars ordered by the president. Man, I feel like the 80’s are about to end or something.
