00:00:00.000 --> 00:00:06.000
Intro music.

00:00:06.000 --> 00:00:10.000
On Tuesday, the crew of the International Space Station completed a spacewalk

00:00:10.000 --> 00:00:15.000
to maintain the station's exterior experiments and prepare for the outpost's future.

00:00:15.000 --> 00:00:20.000
Conducting the spacewalk were Station Commander Gennady Padalka and Science Officer Mike Finke.

00:00:20.000 --> 00:00:25.000
The location for the day's spacewalk focused on the station's Zvezda Service Module.

00:00:25.000 --> 00:00:33.000
The EVA began at 1:58 am Central Time as Padalka and Fincke exited the Pirs airlock connected to Zvezda.

00:00:33.000 --> 00:00:37.000
Once outside, the two spacewalkers made there way to the aft end of the Service Module.

00:00:37.000 --> 00:00:42.000
Their first task was to work on three containers holding material science experiments.

00:00:42.000 --> 00:00:49.000
The experiments have been in operation for as long as 2 1/2 years in a test to determine how various materials endure exposure to space.

00:00:49.000 --> 00:00:56.000
Afterwards, the pair changed out the vehicle's Kromka panels, which measure contaminants from the Service Module's thrusters.

00:00:56.000 --> 00:01:04.000
Next, the spacewalkers shifted to installing a cluster of reflectors and antennas for use with the arrival of next year's Automated Transfer Vehicle.

00:01:04.000 --> 00:01:11.000
With extra time remaining, the crew took the opportunity to inspect a rubber ring associated with the docking port of the Service Module.

00:01:11.000 --> 00:01:24.000
Completing the spacewalk ahead of schedule, Padalka and Finke climbed back inside the station after only four hours and thirty minutes.
