The controversial leader of Russia’s space enterprises, Dmitry Rogozin, has continued a spree of firings that have seen many of the nation’s top spaceport officials fired, arrested, or both.

Most recently, on November 27, Russian media reported that Rogozin fired the leader of the Center for Exploitation of Ground-Based Space Infrastructure, which administers all of Russia’s spaceports. Andrei Okhlopkov, the leader of this Roscosmos subsidiary, had previously faced a reprimand from Rogozin for “repeated shortcomings in his work.” The spaceport organization has more than 12,000 employees.

Earlier this month, Rogozin also fired Vladimir Zhuk, chief engineer of the center that administers Russian spaceports. According to Russian media reports, Zhuk was then arrested for abusing his authority in signing off on water supply contracts.
