After a morning off, Discovery astronauts got back to work moving equipment and supplies to and from the International Space Station and preparing for Tuesday's spacewalk, the third and last planned for their mission.
Mission Specialists Rick Mastracchio and Clayton Anderson configured their tools in the Quest airlock. After a review of spacewalk procedures with other crew members, they will again spend the night in the airlock, its pressure reduced to 10.2 psi. That campout is aimed at reducing the nitrogen in their blood to avoid decompression sickness.
The spacewalk, replanned after difficulties bolting down an ammonia coolant tank on Sunday caused some rescheduling, is to begin at 3:11 a.m. EDT Tuesday and last 6Â½ hours. Activities include finishing the complicated change out of the large ammonia tank assembly, retrieving micrometeoroid shields from outside the airlock and retrieving a light-weight adapter plate assembly.
