STS-104 Delivers Quest to International Space Station
Space Shuttle Atlantis spent 13 days in orbit, eight of those days docked with the International Space Station. While at the orbital outpost, the STS-104 crew delivered the Quest Airlock and installed it on the station's Unity Node.

Expedition Two Flight Engineer Susan Helms used the space station's robot arm, Canadarm2, to lift Quest from the orbiter's payload bay. At the same time, STS-104 Mission Specialists Michael Gernhardt and James Reilly conducted a space walk, guiding Helms' movements as she installed Quest onto the station.

A week later Gernhardt and Reilly would use the brand-new airlock for the third space walk of the mission.

Three Space Walks Prepare Quest for Use
Mission Specialists Michael Gernhardt and James Reilly conducted three space walks while Space Shuttle Atlantis was docked to the International Space Station. They spent a total of 16 hours and 30 minutes outside.

During the first space walk, Gernhardt and Reilly assisted in the installation of the airlock. During the second and third excursions, they focused on the external outfitting of the Quest Airlock with four High Pressure Gas Tanks, handrails and other vital equipment.
