Barry and Forrester installed an Early Ammonia Servicer, or EAS, onto the International Space Station's P6 Truss. With the assistance of the shuttle's robot arm, they attached it to the truss and then attached cables that will supply the EAS with power and data from the station. They also installed the Materials International Space Station Experiment, or MISSE, onto the Quest Airlock. MISSE is housed in two containers and will be removed during a future space walk. This was the 25th space walk devoted to space station construction.

STS-105's second space walk focused on installing handrails on the Destiny Laboratory Module and installing heater cables onto the station's Destiny Laboratory. The cables may be used on shuttle mission STS-110 to power heaters on the station's S0 Truss segment. This was the 26th space walk in support of space station construction.
