1.   Cosmonauts also install a new motion-control computer on the aging Russian outpost.

2.   The National Aeronautics and Space Administration plans for the shuttle to remain linked to Mir long enough for the cosmonauts to install and test the generator.

3.   Cosmonauts must install a metal support beam to the solar panel to provide reinforcement and stop it from breaking away.

4.   The cosmonauts will then install a special hatch that would help to eventually repressurize the Spektr.

5.   The two cosmonauts installed the second of two footholds before starting work on the solar panel, which was damaged in a collision with a cargo ship last June.

6.   Then the cosmonauts will install a new hatch designed to allow power to flow from Spektr into the rest of the station.
