WASHINGTON -- Two members of the Expedition 35 crew will venture 
outside the International Space Station on April 19 for a six-hour 
spacewalk to deploy and retrieve several science experiments and 
install a new navigational aid.

NASA Television will broadcast the spacewalk live beginning at 9:30 
a.m. EDT. Russian flight engineers Pavel Vinogradov and Roman 
Romanenko will open the hatch to the Pirs airlock and docking 
compartment to start the spacewalk at 10:06 a.m.

The spacewalkers' first task will be to install the Obstanovka 
experiment on the station's Zvezda service module. Obstanovka will 
study plasma waves and the effect of space weather on Earth's 

They will retrieve the Biorisk experiment, which studied the effect of 
microbes on spacecraft structures. If time permits, they also will 
retrieve one section of the Vinoslivost experiment, which exposed 
materials samples to space.

While at the far end of Zvezda, Vinogradov and Romanenko will replace 
a faulty retro-reflector device, one of a suite of navigational aids 
that will provide assistance to the European Space Agency's Albert 
Einstein Automated Transfer Vehicle 4 cargo ship during its final 
approach for an automated docking to the space station in June.

This spacewalk will be the 167th in support of space station assembly 
and maintenance, the seventh for Vinogradov and the first for 
Romanenko. Both spacewalkers will wear spacesuits marked by blue 
stripes. Romanenko's suit will be equipped with a helmet camera to 
provide close-up views of the spacewalk activity as it progresses.

This is the first of as many as six Russian spacewalks planned for 
this year. Two U.S. spacewalks are scheduled in July.
