Nebraska astronaut Anderson makes final spacewalk

Nebraska Astronaut Clayton Anderson completed his final space walk Tuesday for the shuttle Discovery mission.

Clayton Anderson ventured out for his 3rd and final space walk of the mission.  Tuesday entailed some tricky handy work fixing a stubborn tank with one of his fellow colleagues.  Nebraska's own Clayton Anderson along with one of his crew members floated out of the International Space station for their 3rd and final space walk for the shuttle Discovery mission.

Anderson and another crew member finished installing an ammonia tank. The activated tank is used for cooling the International Space station.

Floating over 200 miles above earth the pair ran into a problem.  “We ran into some trouble with one of the bolts today and we know the engineers design these devices to have tight tolerances and things just change in space and we understand that,” Anderson said.

The 6 ½ hour spacewalk finished with some last minute prep work for the next shuttle visit…and a few minutes spent taking in the moment.

“Really stunning view…oh baby you're going to want to take this one to the grandkids,” Anderson said.

Discovery will depart the Space Station Saturday and Clayton Anderson and his colleagues will be back here on Earth on Monday.

NASA has only 3 more shuttle missions scheduled before they plan to put the program on hold…
