Maine in Space

Today marks Maine astronaut Chris Cassidy's final spacewalk, the fifth of the shuttle Endeavour's current mission at the international space station, according to WMTW.

Cassidy and Thomas Marshburn will rearrange some power cable hookups, fold down a piece of popped-up insulation on a small robot arm install TV cameras on the porch of the new Japanese lab on the international space station.

NASA will be watching for possible carbon dioxide buildup in the astronauts' space suits during the walk.

You can watch the spacewalk live online on WMTW's website.
