Russia plans more ISS modules

Roskosmos chief Anatoly Perminov says the Russian space agency will build three new modules for the International Space Station by 2011.

The space station, a joint project between Russia, Europe, Canada, Japan and the United States, is likely to remain in operation until 2020, RIA Novosti said Friday.

Perminov said new energy modules will also be added to the station after 2011. The first ISS element, the Russian Zarya module, was put into orbit in November 1998, Novosti said.
