President Barack Obama says he is extraordinarily proud of the astronauts aboard the linked shuttle-space station complex.
During a video conference call Tuesday, Obama questioned the 10 astronauts about everything from how fast they are traveling and to exercising in space. He also asked what they do besides work on experiments and how weightlessness affects their sleep.
Students from Washington area middle schools and members of Congress joined him for the call.
