"Autonomous testing of the mobile service tower for the rocket carrier is successfully completed at the Vostochny Cosmodrome," Rogozin posted on his Twitter account.
The mobile service tower, standing 52 meters high and designed for the pre-launch processing of Soyuz-2-type ILV rockets, is the tallest vertical structure of Vostochny Cosmodrome.
The first launch of a rocket carrier from the Vostochny Cosmodrome was initially scheduled for late 2015 before being postponed. The new rocket launch date has been set for April 25 2016.
The Vostochny Cosmodrome has been under construction in the Amur Region of Russia's Far East since mid-2012. Once Vostochny is completed, it will enable Russia to launch most missions from its own soil, reducing the country's reliance on the Baikonur Cosmodrome in Kazakhstan.
