(Newser) – Two astronauts endured a long spacewalk today to deliver the Columbus lab to the International Space Station, the Houston Chronicle reports. Rex Walheim and Stan Love struggled with heater cables, but guided the 15-ton lab while a station astronaut moved it with a robot arm. The 8-hour walk was the first of three scheduled this week to attach the lab to its orbital outpost.

"Welcome to spacewalking, buddy," Walheim told Love, the stand-in for a German astronaut who fell ill this weekend. "It's awesome," Love said.  Love and Walheim also prepped a nitrogen tank for replacement, and spotted a 2-millimeter ding on the station's exterior. The $2.1 billion research lab is Europe's contribution to the space station.
