Russian "Internal" Spacewalk Complete
Expedition 20 Commander Gennady Padalka and Flight Engineer Michael Barratt completed an “internal” spacewalk Wednesday at 3:07 a.m. EDT.
Padalka and Barratt replaced a Zvezda hatch with a docking cone. The excursion took place internally with the spacewalkers attached to umbilicals in Zvezda for life support. It lasted about 12 minutes.
Docking antennas, a docking target and electrical connectors were installed on the exterior of the Zvezda service module during their first spacewalk Friday.
The station is now ready for the docking of the Mini-Research Module 2, or MRM2, later this year. The MRM2 will dock automatically to the zenith port of Zvezda and will serve as an additional docking port for Russian vehicles.
