HOUSTON — Since humans first flew in space, nothing has captivated astronauts more than the view of home out the window of their spacecraft. In honor of Earth Day, April 22, NASA will make those views available to people here on Earth with an event highlighting imagery taken by astronauts and the science behind it.
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.
