Astronaut Mark Vande Hei made fast work of greasing the big robot arm's new hand. Vande Hei and station commander Randy Bresnik replaced the latching mechanism on one end of the 58-foot robot arm last Thursday. "I finish six months on the space station," Vande Hei replied. As the space station approached Italy early in the spacewalk, Mission Control urged Bresnik and Vande Hei to take some photos for their crewmate, Paolo Nespoli.
