Astronauts from the US space shuttle Endeavour were to venture into open space Monday on the mission's second spacewalk aimed at helping complete the International Space Station. Astronauts Dave Wolf and Tom Marshburn spent part of Sunday preparing special tools, reviewing procedures and beginning their campout in a special decompression chamber in preparation for the walk,
which is set to start at 11:28 am (1528 GMT). The bulk of the Sunday's schedule was taken up with moving equipment from the Endeavour onto the ISS and fixing a malfunctioning toilet system aboard the ISS. The toilet was likely flooded earlier in the day when its dose pump failed after running for about 15 minutes, NASA officials said. As a result, about six liters of pre-treated water may have flowed into the pump separator and other areas, flooding the separator. On 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.
