Your New Desktop Wallpaper: The First Spacewalk of the Shuttle Program

From the archives: On June 7th, 1983, Astronauts Story Musgrave (left) and Don Peterson orbit the Earth at over 17,000 miles per hour, tethered to the cargo bay of the Space Shuttle Challenger on the inaugural spacewalk of NASA's Space Shuttle program. How's that for breathtaking?

I will never get over the sheer power of this photograph (which you really must experience at full resolution). Within it there is depth and there is scale. There is motion and there is stillness. There is power, humility, triumph and achievement. And it is all tremendous.
