Space station astronauts use robot arm, go Twitter
(AP) -- Robotic arm maneuvers and social networking sites are taking center stage at the international space station and space shuttle complex.
The 13 space station and Endeavour crew members were awakened early Tuesday by Mission Control with the Rascal Flatts' song "Life is a Highway."
Not long afterward, crew members began using the shuttle and space station's robotic arms to move a storage pallet holding three experiments from the belly of Endeavour to the outside of a Japanese laboratory at the space station.
The astronauts also will use social networking sites later in the day, taking questions from Earth via Twitter and YouTube.
