The crew prepared for the mission's third and final spacewalk on Flight Day 10.

On the final spacewalk, planned for Wednesday, they will install the tool carrier on the airlock and add another camera to the outside of the station.

The crews spent the remainder of their day configuring tools and reviewing procedures for the flight's final spacewalk.

It was their third and final spacewalk since the shuttle docked with the International Space Station on July 6 for a 13-day mission.

Following the wake up call, the two crews got to work preparing for the mission's final spacewalk.

Flight day 7 featured the third and final spacewalk of mission STS-115.

Afanasyev and Munarov performed the third and final spacewalk of the mission on April 25.

To that effect, mission managers cut the mission's final spacewalk short by two hours, allowing them to land a day earlier than originally planned.

Astronauts retrieve two open-to-space experiment cases from outside station and install a new one before ending the final spacewalk.

The crew will be able to ingress it tomorrow, but the window covers will not be opened until after the third and final spacewalk.
