28 March 2005 -- The two men aboard the International Space Station today began their second spacewalk since arriving at the station last October.
U.S. commander Leroy Chiao and Russian cosmonaut Salizhan Sharipov are scheduled to install antennas that will allow the future docking of a European cargo ship for the first time.
They are also due to manually launch a small experimental satellite.
The space ship will remain unmanned during the space walk that is expected to take up to six hours.
Chiao and Sharipov are scheduled to return to Earth in April.
