The space shuttle Endeavour's seven-member crew spent a busy day on the International Space Station (ISS) on Sunday, preparing for the second of five scheduled space walks, NASA said.
The crew were awakened at 5:13 am Central Time (1013 GMT) to the sounds of "Learning to Fly" by Tom Petty and the Heartbreakers, a song chosen by one of the crew members.
The bulk of the day's schedule was taken up with moving equipment from the Endeavour onto the ISS, and with preparations for Monday's space walk.
Astronauts Dave Wolf and Tom Marshburn will prepare their space suits and tools for the walk, while four other members of the crew install the Integrated Cargo Carrier, which is loaded with replacement batteries for the ISS.
Later Sunday, Canadian astronaut Julie Payette and flight engineer Bob Thirsk are scheduled to talk with Canadian news media and dignitaries via audiolink, the US space agency said.
Saturday, Tim Kopra and Wolf carried out a five hour and 32 minute spacewalk to complete construction of the Japanese Kibo laboratory.
"The third and final piece of Japan's Kibo laboratory was assembled on orbit Saturday, a symphony of robotic and spacewalking performances by the 13 member orchestra aboard the International Space Station complex," NASA said in a statement.
The 1.9-tonne unit known as the Japanese Exposed Facility (JEF), will serve "as a type of porch for experiments that require direct exposure to space," NASA said.
Earlier, on their first full day in space, the Endeavour crew of six Americans and one Canadian tested rendezvous equipment, installed a camera for the orbiter docking system and extended the docking ring that sits on top of the system.
The Endeavour mission aims to help fulfill "Japan's hope for an out-of-this-world space laboratory," as the shuttle delivers state-of-the-art equipment to conduct experiments in the vacuum of space, according to NASA.
The shuttle successfully docked at the space station Friday amid questions about the integrity of the shuttle's heat shield tiles.
However NASA on Saturday said that a close analysis of pictures of Endeavour's heat shield confirmed the absence of any damage.
During the delicate docking maneuver Friday the two space vehicles traveled at 28,000 kilometers (17,398 miles) per hour as they approached each other, giving Commander Mark Polansky a margin of error of 4.5 centimeters (1.8 inches) to complete the procedure, NASA said.
The entry of Endeavour's crew aboard the ISS brought the number of astronauts inside the orbiting space station to a record 13.
Endeavour crew member Kopra will be staying aboard the ISS, taking over from Japanese engineer Koichi Wakata, who has been in space for 124 days.
The ISS should be completed in 2010, also the target date for the retirement of the US fleet of three space shuttles.
