FINAL ACT: Space shuttle Atlantis landed in Florida this morning, bringing an end to NASA's 30-year shuttle program. Just 21 minutes before the de-orbit burn, a photographer in Germany snapped what may be the last-ever photo of a shuttle in space. He caught Atlantis transiting the face of the sun, silhouetted against a backdrop of solar fire in conjunction with nearby sunspot AR1254.
