A chat with NASA astronaut John Herrington

Commander John Herrington is a retired NASA astronaut and member of the Chickasaw Nation. In 2002, he became the first registered member of a Native American tribe to fly in space. During this previously recorded live discussion, we spoke with him about what it’s like sleeping in space, what he took with him on his mission and his role in the stunning new IMAX film Into America’s Wild 3D.
