MOSCOW. Sept 6 (Interfax) - Cosmonauts will have to take nine spacewalks in order to fully launch the new Nauka module onboard the International Space Station (ISS), Alexander Kaleri, head of the Flight-Space Center of Russia's Energia Rocket and Space Corporation, said.
"It takes nine spacewalks for it to be put in service and start working," Kaleri said during a livestream by the Russian space corporation Roscosmos on Friday.
Three spacewalks will be dedicated to integrating the module's and the station's systems. Another three spacewalks are needed to install the Era manipulator. Cosmonauts will use the last three spacewalks to install additional equipment, he said.
