"Bye, Dmitri!" tweeted Jonathan McDowell, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics.
It's unclear what Rogozin's next gig will be, but according to Russian news site Meduza, he could soon be overseeing operations in eastern Ukraine after repeatedly threatening neighboring countries with missile strikes — a move that would blur the lines between firing and promotion.
The news comes after Rogozin repeatedly lashed out at Western partners, particularly following Russia's invasion of Ukraine. He has garnered a reputation for making thinly-veiled threats, provocative statements, and going on countless unhinged rants, sometimes directed at fellow Twitter addict, SpaceX CEO Elon Musk.
Rogozin went as far as to threaten the US with a plummeting International Space Station during the early days of the Russia's invasion earlier this year.
"Since the invasion of Ukraine, Rogozin has been increasingly bellicose and made numerous threats about Russian participation in the station," Ars Technica senior space editor Eric Berger, a close Rogozin watcher, tweeted in response to the news of the sacking. "While most of those threats have ended up being hollow, they have damaged working relations with the west."
Berger himself has repeatedly butted heads with Rogozin on Twitter, with the former space program head even accusing Berger of war crimes last year.
The news could take a massive load of pressure off NASA, which has been trying to keep operations on board the ISS going in spite of Rogozin's provocations.
The space agency is still planning to go ahead with a scheduled astronaut seat swap, allowing Russian cosmonaut Anna Kikina to travel to the ISS on board a SpaceX Crew Dragon spacecraft in September.
"No one is happier this morning than [NASA's] Johnson Space Center, from the astronaut office to the corner office to comms," Berger wrote in a follow-up. "Rogozin was a nightmare to work with and a destabilizing force in the ISS partnership."
"He was also a nationalist asshole, of course," Berger concluded.
While the international space community can breathe a little easier, having a belligerent and trigger-happy crony at the helm of an active warzone isn't exactly the most reassuring of prospects either.
The Kremlin has yet to announce what its official plans for Rogozin are next — but we already dread to hear where he's headed next.
