Astronauts prepare to open new space station room

Their first wave of construction work successfully completed, the 10 astronauts aboard the shuttle Discovery and the international space station eagerly awaited their entrance today into the latest addition to the orbiting complex.

Astronauts added the school bus-sized room – called Harmony – during a 6.5-hour spacewalk yesterday, using a robotic arm to lift it from the shuttle’s cargo bay and install it on the station.
