Scott Kelly

Dmitry Rogozin, director of Russia's Roscosmos space agency, shared footage of a large crater created by one of Russia's new Sarmat nuclear-capable missiles.

Kelly, a former astronaut, and retired army officer Mark Hertling published Twitter threads detailing weaknesses of the T-72 battle tank.

As Russia's space agency has become isolated due to global backlash over Ukraine, Kelly said he doubts the U.S. will ever work with them again under Putin.

Kelly told Newsweek some of his former colleagues believe the invasion of Ukraine was to "prevent Nazis and NATO from destroying Russia."

The "Communist Manifesto" author's name donned a study room at the University of Florida since 2014, but officials said world events led to the name's removal.

Kelly, a former NASA astronaut, said he will keep sharing "accurate news" about the war in Ukraine with his Russian followers.

Rogozin, director general of Roscosmos, blocked Kelly after apparently calling him a "moron" as Russia's space program becomes increasingly isolated.

Kelly hit out at the Roscosmos director after he shared footage of foreign flags being stripped from a Russian rocket.
