Padalka completed his sixth career spacewalk on 3 September 2004 when he and Mike Fincke ventured out into space. The spacewalk took place outside the Zvezda module. Padalka and Fincke began the spacewalk at 16:43 GMT, after emerging from the Pirs airlock. On the Zarya module, the two spacewalkers replaced a pump control panel that measures the module's coolant levels. They also installed three communications antennas at its aft end of the Zvezda module. The spacewalk lasted 5 hours and 21 minutes.
