NASA to Broadcast Earth Views in HD

HOUSTON — Since humans first flew in space, nothing has captivated astronauts more than the view of home out the window of their spacecraft.

For the first time ever, NASA Television will air a special hour-long broadcast of views of Earth taken in HD, by astronauts on past space shuttle and International Space Station missions.
