Russian cosmonauts Oleg Kotov and Maxim Surayev have completed this year's first spacewalk and returned to the International Space Station, Mission Control said Thursday.
Wearing Orlan-MK computerized spacesuits, the Russians connected cables between the Poisk and Zvezda modules, installed docking targets and Kurs aerials and attached additional handrails to exit hatches.
They also had to remove the Biorisk-MSN experiment container from the exterior of the ISS.
The container was in position for 30 months and will be returned to Earth in the spring to allow scientists to study the effects of space flight on microorganisms as part of research into the problems of ecological safety and planetary quarantine.
Besides Surayev and Kotov, the ISS crew comprises U.S. astronauts Jeff Williams and Timothy Creamer as well as Japan's Soichi Noguchi.
