This is a particularly interesting self-portrait, in part because it was taken by an astronaut of himself in space, but even more so because of the reflection in the glass of his helmet. Visible in the image, working in from the outer borders, are the edges of the reflecting helmet of a space suit, modules of the International Space Station (ISS), the Earth, the arms of Expedition 15 astronaut Clay Anderson, and the digital camera used to snap the image. This picture was taken during the shuttle orbiter Endeavour’s mission to expand the space station last August.
