European Space Agency astronaut Christer Fuglesang is visible in the reflection of NASA astronaut Danny Olivas's helmet visor during this, the STS-128 mission's third and final spacewalk.
Olivas and Fuglesang deployed the Payload Attachment System, replaced the Rate Gyro Assembly #2, installed two GPS antennae and worked to prepare for the installation of Node 3 next year.
