Spacewalk (STS-110) Poster

Astronaut Jerry L. Ross, STS-110 mission specialist, anchored to the mobile foot restraint at the end of the International Space Station’s (ISS) Canadarm2, works in tandem with astronaut Lee M. E. Morin (out of frame), mission specialist, during the fourth and final scheduled session of extravehicular activity (EVA) for the STS-110 mission. The major task was the installation of a beam, which is called the Airlock Spur, between the Quest Airlock and the S0 (S-zero) Truss. The spur will be used by spacewalkers in the future as a path from the airlock to the truss. Ross and Morin also installed handrails onto the S0, partially assembled a platform, installed two floodlights and performed several other tasks preparing for upcoming assembly missions.
