Astronauts prepare for second space walk
Astronauts aboard the international space station are gearing up for a second space walk today, preparing to work on the outside of the new Harmony addition and inspect a couple areas of concern on the orbiting outpost.
Space walkers Scott Parazynski and Daniel Tani also plan to detach a 35,000lbs space station girder so it can be relocated later in the mission.
Once the pair detaches the bolts and cables that hold the girder in place, astronauts inside the station plan to use a robotic arm to move the truss to a location where it can be temporarily parked. Installation is set for Tuesday during the mission's third spacewalk.
