International Space Station Gets a New "Eye" on the Cosmos

By photographing oblique views with different sun angles, the astronauts can use the Cupola to give scientists a view of the Earth that is not available from satellites. Astronaut photographs of Earth have been used to understand Earth processes such as melting of icebergs, noctilucent clouds, dust storms, and the structure of hurricane eyes.

The crew of the International Space Station (ISS) is about to get a new "eye-pod." The Tranquility node headed for the space station early in 2010 will feature a viewing dome unlike any other window ever flown in space. The dome, called the Cupola, is literally studded with windows for observing Earth, space, and the marvelous expanse of the ISS itself.

The Cupola, named after the raised observation deck on a railroad caboose, is designed as an observation platform for operations outside the station--e.g., robotics, spacewalks, and docking spacecraft. Computer workstations inside the dome will give astronauts full control over the space station's robotic arm and dexterous manipulator, while the windows offer unparalleled views of these devices in action.

"Crews tell us that Earth gazing is important to them," says Julie Robinson, the ISS Program Scientist at NASA's Johnson Space Center. "The astronauts work hard up there and are away from their families for a long time. Observing the Earth and the stars helps relax and inspire them."

Until now, space station astronauts have been confined to looking out small portholes or at best the 20-inch window in the US Destiny Laboratory. The Cupola will dramatically expand their view.

"The Cupola's 80-cm diameter circular top window is the largest window ever built for space," says Robinson. "Rather than peering through a little porthole, the Cupola will allow a stunning look at the cosmos and unprecedented panoramic views of Earth. Astronauts will share these views with the world through photographs taken through the windows and posted online."
