CAPE CANAVERAL, Fla. (AP) -- A couple of husky astronauts whose first spacewalk was a tiring, difficult affair ventured back outside Saturday for another round of construction work on the international space station.
Spacewalk No. 2 got under way by late morning, with David Wolf and Piers Sellers resuming the installation of a new girder some 245 miles up.
"Here comes the hatch," said Sellers, the first one out.
The two men, visiting from space shuttle Atlantis, had trouble with stuck bolts, entangling shrouds and a balky construction crane during their spacewalk Thursday, which went into overtime at seven hours. The hardest part came near the end when they had to install a TV camera without the benefit of the space station's robot arm as a work platform.
