From the NASA website 7/22/10,
"The International Space Station has had guests from all over the world, representing myriad languages. But until NASA astronaut Tracy Caldwell Dyson came aboard, one language was still not represented. Said to be the fourth most commonly used language in the United States, American Sign Language, or ASL, made its debut on the space station in a special video recorded by Caldwell Dyson.
In the almost six-minute video, the American astronaut spoke directly to the deaf community about what she does on the space station and how she became interested in ASL. She even offered several words of encouragement for young deaf students."
