Final Shuttle-Era Spacewalk On Tap At ISS

America's last shuttle-era spacewalk is on tap at the International Space Station today.

Station flight engineers Mike Fossum and Ron Garan will venture outside the outpost at 8:45 a.m., aiming to retrieve a failed ammonia coolant pump for a return to Earth and set up a robotic refueling experiment package outside the U.S. Destiny laboratory. The station's two-armed Canadian robot Dextre will work with the experiment after the shuttle crew departs the outpost.

You can watch the 6.5-hour excursion unfold right here in The Flame Trench. Click the NASA TV box on the right side of the page for live NASA TV coverage of the 160th spacewalk to be performed in the assembly and maintenance of the station.
