Russia's Progress MS-21 cargo spacecraft successfully docked with the Russian segment of the International Space Station (ISS) early Friday, the website of Russia's state space corporation Roscosmos reported.

The docking process was supervised from the ground by specialists from the Mission Control Center, and also by the ISS crew, including cosmonauts Sergey Prokopyev, Dmitry Petelin and Anna Kikina, Russia's state media TASS reported.
