Tank and spacewalker on robot arm
Schlegel and Walheim
Spacewalker rides robot arm while holding tank
Riding the space station robot arm, Rex Walheim is holding the nitrogen tank assembly, while robot arm operator Leland Melvin moves the arm toward the space station.
"This is a great ride," said Walheim, who also asked about his clearance as he moved out of the shuttle payload bay.
Hans Schlegel, meanwhile, climbed up the space station to meet Walheim.

The nitrogen tank assembly (NTA) sits in the payload bay beneath two European experiments, SOLAR and EUTEF. The spacewalkers will return the old tank to the payload bay.
