Shuttle Mission: STS-111
Orbiter: Endeavour
Date: June 5, 2002

Image: Montage of images including the Space Shuttle and American FlagThe primary objectives of the STS-111 crew are to perform the fourth crew exchange aboard the International Space Station, install the Mobile Base System or MBS, and repair the Station's robotic arm. The crew will also transfer hardware and experiments from the Leonardo Multi-Purpose Logistics module, built by the Italian Space Agency.

The MBS is the second part of the Canadian-built Mobile Servicing Structure that will give the Station's robotic arm, or Canadarm2, its unique mobility. During the first two of three spacewalks, mission specialists will attach the MBS to the Mobile Transporter that was installed during STS-110 and transfer the Station's robotic arm from the U.S. Destiny Lab to the MBS. This will allow the arm to travel the length of the S-Zero Truss that was delivered during our last mission, as well as future truss segments.

During the third and final spacewalk, the astronauts will repair the wrist/roll joint on Canadarm2. A new unit, called an Orbital Replacement Unit, will be installed next to the Latching End Effector at the end of the arm. The wrist/roll joint is one of seven joints that contribute to the arm's flexibility.
