STS-110 Mission Specialists Jerry L. Ross and Lee M.E. Morin work in tandem on the fourth scheduled EVA session for the STS-110 mission aboard the Space Shuttle Orbiter Atlantis. Ross is anchored on the mobile foot restraint on the International Space Station's (ISS) Canadarm2, while Morin works inside the S0 (S-zero) truss. The STS-110 mission prepared the Station for future spacewalks by installing and outfitting a 43-foot-long S0 truss and preparing the Mobile Transporter. The 27,000 pound S0 Truss was the first of 9 segments that will make up the Station's external framework that will eventually stretch 356 feet (109 meters), or approximately the length of a football field. This central truss segment also includes a flatcar called the Mobile Transporter and rails that will become the first "space railroad," which will allow the Station's robotic arm to travel up and down the finished truss for future assembly and maintenance. The completed truss structure will hold solar arrays and radiators to provide power and cooling for additional international research laboratories from Japan and Europe that will be attached to the Station. Milestones of the S-110 mission included the first time the ISS robotic arm was used to maneuver spacewalkers around the Station and marked the first time all spacewalks were based out of the Station's Quest Airlock. It was also the first Shuttle to use three Block II Main Engines. The Space Shuttle Orbiter Atlantis, STS-110 mission, was launched April 8, 2002 and returned to Earth April 19, 2002.

Launched aboard the Space Shuttle Orbiter Atlantis on April 8, 2002, the STS-110 mission prepared the International Space Station (ISS) for future space walks by installing and outfitting the 43-foot-long Starboard side S0 (S-zero) truss and preparing the first railroad in space, the Mobile Transporter. The 27,000 pound S0 truss was the first of 9 segments that will make up the Station's external framework that will eventually stretch 356 feet (109 meters), or approximately the length of a football field. This central truss segment also includes a flatcar called the Mobile Transporter and rails that will become the first "space railroad," which will allow the Station's robotic arm to travel up and down the finished truss for future assembly and maintenance. The completed truss structure will hold solar arrays and radiators to provide power and cooling for additional international research laboratories from Japan and Europe that will be attached to the Station. STS-110 Extravehicular Activity (EVA) marked the first use of the Station's robotic arm to maneuver space walkers around the Station and was the first time all of a shuttle crew's space walks were based out of the Station's Quest Airlock. In this photograph, Astronaut Jerry L. Ross, mission specialist, anchored on the end of the Canadarm2, moves near the newly installed S0 truss. Astronaut Lee M. E. Morin, mission specialist, (out of frame), worked in tandem with Ross during this fourth and final scheduled session of EVA for the STS-110 mission. The final major task of the space walk was the installation of a beam, the Airlock Spur, between the Quest Airlock and the S0. The spur will be used by space walkers in the future as a path from the airlock to the truss.

STS-110 mission specialist Lee M.E. Morin carries an affixed 35 mm camera to record work which is being performed on the International Space Station (ISS). Working with astronaut Jerry L. Ross (out of frame), the duo completed the structural attachment of the S0 (s-zero) truss, mating two large tripod legs of the 13 1/2 ton structure to the station's main laboratory during a 7-hour, 30-minute space walk. The STS-110 mission prepared the Station for future space walks by installing and outfitting the 43-foot-long S0 truss and preparing the Mobile Transporter.

Hovering in space some 240 miles above the blue and white Earth, STS-110 astronaut M.E. Morin participates in his first ever and second of four scheduled space walks for the STS-110 mission. He is seen toting one of the S0 (S-Zero) keel pins which were removed from their functional position on the truss and attached on the truss' exterior for long term stowage. The 43-foot-long, 27,000 pound S0 truss was the first of 9 segments that will make up the International Space Station's external framework that will eventually stretch 356 feet (109 meters), or approximately the length of a football field. This central truss segment also includes a flatcar called the Mobile Transporter and rails that will become the first "space railroad," which will allow the Station's robotic arm to travel up and down the finished truss for future assembly and maintenance. The completed truss structure will hold solar arrays and radiators to provide power and cooling for additional international research laboratories from Japan and Europe that will be attached to the Station. The mission completed the installations and preparations of the S0 truss and the Mobile Transporter within four space walks. STS-110 Extravehicular Activity (EVA) marked the first use of the Station's robotic arm to maneuver space walkers around the Station and was the first time all of a shuttle crew's space walks were based out of the Station's Quest Airlock. It was also the first Shuttle to use three Block II Main Engines. The Space Shuttle Orbiter Atlantis STS-110 mission was launched April 8, 2002 and returned to Earth April 19, 2002.
