If time permits, the pair also will deploy a Payload Attachment System on the Starboard 3 truss structure that will allow an external spare parts stowage platform to be installed on a future shuttle mission.

The six-and-a-half-hour spacewalk also includes an electrical cable swap and adjustment of insulation blankets on the Special Purpose Dexterous Manipulator. The HTV is scheduled to make its first deliveries to the station in September. The primary objective of the spacewalk is to install two cameras on Japan’s Kibo laboratory that will provide views to help with rendezvous and berthing of the H-II Transfer Vehicle (HTV). Spacewalkers Chris Cassidy and Tom Marshburn spent the night camped out in the Quest airlock. The final full day of activities for the joint crew of Endeavour and the International Space Station will focus on the fifth and final spacewalk of the mission.
