Spacewalkers Scott Parazynski and Dan Tani have disconnected nine power-and-data cables running between two truss segments atop the U.S. Unity module as work to relocate one of them continues outside the International Space Station.
Parazynski has loosened four bolts that secure the P6 solar array truss to the base its been mounted atop since its delivery to the station seven years ago. Tani also has released four grounding straps.
Live images are being beamed back from the astronauts' "helmet-cams" -- small cameras the size of lipstick tubes that are mounted to their helmets. You'll hear the spacewalkers refer to them as their "WVS" -- Wireless Video System.
Check out the faint numbers in the bottom right corner of the helmet-cam images to determine who is giving you an up-close view of the work going on outside the international outpost. The number 18 indicates the view is coming from Tani's helmet-cam. Views from Parazynski's helmet-cam have the faint number 16. It's the next best thing to being there.
