Atlantis astronauts spacewalk again

Atlantis mission specialists Stephen Bowen and Michael Good kicked off the second mission spacewalk on Wednesday morning.

Bowen's first job was to try to free a snagged cable on the end of the shuttle's inspection boom. The tangled cord is preventing the astronauts from thoroughly inspecting their ship for any possible damage.

The rest of the spacewalk was devoted to battery work. Bowen and Michael Good replaced three old space station batteries. Three more will be replaced Friday during the third and final spacewalk of the mission.
