International Space Station Commander Mike Fincke and Flight Engineer Yury Lonchakov wound up a 5-hour, 38-minute spacewalk to install an electromagnetic energy probe and other experiments at 1:29 a.m. EST Tuesday.

They also took photos. The spacewalk, in Russian Orlan spacesuits from the station's Pirs docking compartment, began at 7:51 p.m. Monday.

Lonchakov, the lead spacewalker, completed his first spacewalk. Fincke completed his fifth spacewalk.

Lonchakov and Fincke worked together to install the electromagnetic energy measuring device, called a Langmuir probe, on Pirs. Measurements of electromagnetic energy could be helpful in the investigation of its effects on pyrotechnical separation bolts on Soyuz spacecraft. The bolts are suspects in the investigation of ballistic - steeper than normal -- entries of the Expedition 15 and Expedition 16 Soyuz spacecraft.

Hello All,

Did you ever see Santas in Space?
