On Friday astronauts completed their fourth and final spacewalk of the Endeavour’s last space mission.
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.
