The Space shuttle crew then moved back into their shuttle to undock their ship. Endeavour’s commander Mark Kelly thanked the space station's crew members for their support and hospitality and called their mission a success.

Mark Kelly said, “We got the Alpha Magnetic Spectrometer installed, which is really a remarkable thing for physics and for science. That sensor's already collecting massive amounts of data and we're looking forward to hearing what those discoveries are.”

The astronauts in the final spacewalk moved the robotic arm of Endeavour to its new home. The robotic arm is 50 foot in size and it will be placed on International Space Station.

The spacewalk was the last spacewalk of NASA’s space shuttle mission. In the 12 years of shuttle missions, NASA astronauts completed 1000 hours of spacewalk.

Astronauts did the spacewalk for about five hours and passed the 1000 hours of spacewalk mark. Astronauts and cosmonauts have spent this time for the maintenance of space shuttles and space station.

The spacewalk lasted for six hours and 19 minutes and came to an end after the sensor in the spacesuit of one of the astronauts brokdown. A carbon dioxide sensor in Greg Chamitoff spacesuit brokdown and the space walk came to an end at 9:29am Eastern Time.

As the carbon dioxide sensor failed, the officials did not have any way to monitor the carbon dioxide level in his suit, however he was not in any danger at that time.
