HOUSTON (AP) -- Two spacewalking astronauts floated out of a hatch on the international space station on Monday to help install a new European lab, while a crewmate who was supposed to participate in the outing helped from inside.
Spacewalkers Rex Walheim and Stanley Love ventured outside as the space station passed over Asia.
"Welcome to spacewalking buddy," Walheim said as Love made his way through the hatch for his first spacewalk.
"It's awesome," Love replied.
German astronaut Hans Schlegel was supposed to be Walheim's spacewalking partner, but he was pulled from the job Saturday because of an undisclosed illness. Schlegel looked and sounded well Sunday and was expected to take part in the second spacewalk of the mission on Wednesday. On Monday, however, he was helping choreograph the outing from inside the station.
The first job for the spacewalkers was attaching a handle to Columbus that will allow robotic arm operator Leland Melvin to grab hold of the module and delicately lift it from Atlantis' cargo bay.
Perched at the end of the robotic arm, Love carefully unbolted the handle from the side of the shuttle's cargo bay. Meanwhile, Walheim disconnected cables from the shiny RV-sized Harmony module and removed debris shields to make room for the handle. Then both began bolting the handle to the module, struggling a bit with some of the connections.
"Try jiggling it a little bit," Walheim told Love about one of the bolts.
"I think it's in," Love said with a laugh a few moments later.
Later Monday, Melvin will install Columbus on the right side of the Harmony module, which Discovery's astronauts delivered in December.
The 10-ton Columbus laboratory is Europe's main contribution to the space station.
The original plan called for the module to be launched in 1992 to mark the 500th anniversary of Christopher Columbus' voyage to the New World. Since then, the $2 billion lab has endured space station redesigns and slowdowns, as well as a number of shuttle postponements and two shuttle accidents.
"It's getting more exciting here for us every day," a European flight controller said Monday. "... We're looking forward to a successful Columbus installation today."
"This will be a big day for us," replied French Air Force Gen. Leopold Eyharts, who arrived at the station aboard Atlantis to spend a month setting up and activating the new lab.
With their flight now 12 days long because of the spacewalk delay, Atlantis' astronauts conducted another survey of a thermal blanket that has a torn corner; the stitching came apart at the seams, and the corner pulled up.
Engineers were analyzing the problem to determine whether the blanket would stand up to the intense heat of re-entry at flight's end, or whether spacewalk repairs might be needed. The blanket is located on the right orbital maneuvering system pod, back near the shuttle's tail.
NASA is vigilant when it comes to the shuttle's thermal shielding, ever since Columbia was destroyed in 2003 following a foam strike to its wing during launch.
John Shannon, chairman of the mission management team, said the thermal covering on the wings, nose and belly of Atlantis have no areas of concern and have been cleared for re-entry in just over a week.
