Dmitry Rogozin has been removed from his post as director general of the Roscosmos, the state corporation that runs Russia’s space program, according to press reports. Rogozin is being replaced by former Deputy Prime Minister Yuri Borisov.

Rogozin was appointed head of Roscosmos in May 2018. He was previously deputy prime minister overseeing the military-industrial complex, which included the space and defense sectors. Borisov replaced him in that role at the time.

Rogozin has been increasingly bombastic since the Russian invasion of Ukraine earlier this year. He made threats that Russia would launch nuclear weapons at nations supporting Ukraine. Rogozin also said Russia would pull out of the International Space Station program, which is a partnership of the United States, Europe, Japan and Canada.

Rogozin got into Twitter fights with a number of former NASA astronauts, who had nothing good to say about his tenure leading Russia’s space program.

Although he is out at Roscosmos, Rogozin’s career in the Russian government doesn’t appear to be over, according to Anatoly Zak of RussianSpaceWeb.com.

“Following its tumultuous tenure as the head of Roskosmos, Rogozin was expected to move to the presidential administration and, possibly, lead it or ‘curate’ the Russian occupation of the Eastern Ukraine, the independent Meduza publication reported,” Zak wrote.
