However, the medium resolution camera again experienced telemetry issues.

The cosmonauts then removed a worksite interface adapter attached to a portable data grapple fixture on the Zarya cargo module. The adapter removal work will ensure that future operations with the Canadarm2 robotic arm will not be impeded.<\/p>\n\n\n\n<p>This was the fourth spacewalk conducted during Expedition 38 and the 178<sup>th<\/sup> in support of space station assembly and maintenance.

Both spacewalkers wore Russian Orlan spacesuits bearing blue stripes.<\/p>\n\n\n\n<p>The first two spacewalks were conducted Dec. 21 and Dec. 24 by NASA astronauts Rick Mastracchio and Mike Hopkins.
