STS110-E-5516
July 20, 2011
Astronauts Lee M.E. Morin (left, with feet in restraint) and Jerry L. Ross (partially inside truss at right) work on the International Space Station during the STS-110 mission's second extravehicular activity. Morin and Ross completed the structural attachment of the truss--the newest component of the orbital outpost, mating two large tripod legs of the 13-ton structure to the stations main laboratory during a 7-hour, 30-minute spacewalk. The station will ultimately span some 350 feet from end to end, slightly longer than a football field. The work of the two mission specialists complemented that of the previous day by astronauts Steven L. Smith and Rex J. Walheim.
