A unique recording will be featured at the 9/11 Memorial Museum when it opens in 2012: Frank Culberston, the only American not on Earth on September 11, 2001, watched the burning towers from the International Space Station.
"It was pretty difficult to think about work after that, though we had some to do, but on the next orbit we crossed the US further south. All three of us were working one or two cameras to try to get views of New York or Washington," Culberston wrote in his journal the following day.
Below is Culberston's transmission from space on September 11, 2001.
