Astronauts add new room to space station

CAPE CANAVERAL, Florida (Reuters) - The shuttle Discovery astronauts added a room to the International Space Station on Friday, extending the orbital outpost so Europe and Japanese laboratories can be linked in as well.

The work, one of the primary jobs of the shuttle's 14-day mission, began with veteran spacewalker Scott Parazynski and rookie Douglas Wheelock slipping outside the space station's Quest airlock to prepare the module for installation.

Robot arm operators working inside the station's Destiny laboratory fished out the 31,500-pound (14,200-kg) Harmony module from the shuttle's cargo bay and hoisted it over the side of the shuttle and into a temporary position on the station's Unity connecting node.

Unity connects the Russian and American segments of the station.

Space station astronauts will reposition Harmony, which boosts the station's living space by 18 percent, to its permanent spot after the shuttle leaves the outpost on November 4. The module, which has six attachment ports for future station expansion, needs to be where the shuttle is now docked.

"I don't know that anybody ever told our crew that we bring harmony with us, but we sure bring fun," joked Discovery commander Pamela Melroy as Parazynski and Wheelock relaxed in the airlock after finishing the first of five spacewalks planned during the shuttle's visit.

Before placing the Harmony connecting node onto the station, the spacewalkers worked on a massive solar power structure that will be repositioned during spacewalks on Sunday and Tuesday. They also retrieved a broken antenna that will be refurbished on Earth and returned to the station as a spare.

During Sunday's outing, the spacewalkers will inspect a huge rotary joint that spins a pair of the station's solar power panels to face the sun. Engineers have noticed a vibration and want to know if anything is physically interfering with the gear.
