"Space Junk" continued to vex the US space agency, NASA and its crew at the International Space Station that were forced to reposition the ISS and the space shuttle Discovery, on Sunday, to dodge a piece of space debris, which could come dangerously close during the scheduled spacewalk on Monday.

NASA reported that on Sunday, the shuttle commander Lee Archambault fired up steering jets of the space shuttle Discovery, still docked at the International Space Station, to move the shuttle to a new position, to reduce the chances of its collision with a piece of space debris.

According to the space agency, the ISS and the shuttle were turned 180 degrees with the shuttle leading the station as it orbits Earth. The new position will help the station and shuttle to avoid the potentially dangerous piece of debris.

NASA said, "Had we not taken this action, the first time of closest approach would have been about two hours into Monday's spacewalk."

The space agency told that the space debris is part of a spent Chinese satellite. The agency also revealed that the astronauts will take today's Space walk to fix an improperly installed cargo platform attachment. NASA also told that it has called off tests of the urine recycler of ISS on Sunday after problems developed.
