the people aboard sts-122 had several jobs to do. the main job was to add the new room, or module, "columbus", to the space station. to do this, a robot arm, called a remote manipulator system, or rms, will be used to lift "columbus" out of the space shuttle, and move it over to a gap in the side of the space station. two of the crew will then go outside, and fit parts to the module. "columbus" will be used for scientific research.
