DENVER — An extraordinary war of words is transpiring between the head of Russia's space agency and one of NASA's most famous former astronauts as the U.S.-Russian partnership at the International Space Station hits its lowest point since its inception.

Scott Kelly, who famously spent a year in space aboard the station, has been blocked on Twitter by Roscosmos Director General Dmitry Rogozin after Kelly criticized Russia's invasion of Ukraine and Rogozin's repeated threats to pull out of the International Space Station, typically a venue of cooperation immune from geopolitical chaos.

"Get off, you moron!" Rogozin said in a quickly deleted Tweet. "Otherwise, the death of the International Space Station will be on your conscience."

"Dimon, why did you delete this tweet?" Kelly replied in Russian. "Don't want everyone to see what kind of child you are?"

In an interview with CNN, Kelly described it as "the first Twitter argument I've ever had."

On Wednesday, Kelly announced on Twitter — in Russian — that he was returning a medal awarded to him in 2011 by former Russian President Dmitry Medvedev.

"Mr. Medvedev, I am returning to you the Russian medal 'For Merit in Space Exploration,' which you presented to me," Kelly wrote, according to a translated version of the tweet. "Please give it to a Russian mother whose son died in this unjust war. I will mail the medal to the Russian embassy in Washington. Good luck."

The tweet came in response to a post from Medvedev that wished women a "Happy Holidays."

Social media propaganda

Kelly said in an interview earlier this week that he felt compelled to speak out after Rogozin shared a Roscosmos-produced video showing two Russian cosmonauts floating inside the space station waving goodbye to NASA astronaut Mark Vande Hei, who is supposed to return to Earth with them on a Russian Soyuz spacecraft on March 30.

"If he's going to act like a child, then I'm going to treat him like one," Kelly said. "It's just unimaginable that the Russian space program would leave a person behind in space that they were responsible for bringing home. I don't see that happening."

But Kelly quickly reconsidered after remarking how he also thought it was inconceivable that Russia would launch a full-scale invasion of Ukraine.

"Even though I just said it was unimaginable, maybe they might leave a person behind. I don't know," Kelly said.

There are currently four NASA astronauts, two Russian cosmonauts, and one European Space Agency astronaut living and working aboard the International Space Station. But Vande Hei is the only NASA astronaut featured in the fictitious Roscosmos video.

"If I was him, I would feel like I'm just going to keep doing my job," Kelly said. "And if they (Roscosmos) want to leave me up here, then I'll find another way home."

Kelly, who is fluent in Russian after spending several years training in Moscow's Star City, commends most Roscosmos employees for being "professional, reasonable people" who "want this partnership to continue."

International cooperation

NASA has remained silent on Rogozin's most recent threats to abandon Vande Hei and detach the Russian segment from the space station. But last week, NASA said there were no signs Russia was withdrawing its support from the International Space Station as a result of U.S. sanctions.

"We are not getting any indications at a working level that our counterparts are not committed to ongoing operation on the International Space Station. We as a team are operating just like we're operating three weeks ago," said Kathy Lueders, NASA's associate administrator for space operations.

The space station has been a beacon of international cooperation for more than two decades, and Kelly remains confident it can continue.

"NASA can do really amazing things when they put their minds to it, and I do think they can hold this partnership together," Kelly said.

But he also noted that "sometimes things become more important than spaceflight. In this case, it's Russia waging a war against an innocent country. And if I have the ability to speak up and get attention, and to help the Russian people see the truth, then I'm going to do it."

Ridesharing in space

For nearly a decade, Russia's Soyuz vehicles had been the only means of getting astronauts to and from the space station. But that reliance ended after SpaceX debuted its Crew Dragon capsule in 2020, and the U.S. regained human spaceflight capabilities.

There are, however, tentative agreements for U.S. astronauts to ride on Russian Soyuz vehicles and for Russian cosmonauts to fly with SpaceX in the future. NASA said in a statement Tuesday that it "continues to work toward an agreement with Roscosmos."

In addition to Vande Hei's slated to return to Earth on a Soyuz vehicle later this month, NASA astronauts routinely travel to Russia for training and vice versa.

Boeing is also working on its own crewed capsule that could be capable of ferrying astronauts to the space station for the United States and its partners. That project, however, is years behind schedule. It is beleaguered with hangups. The latest update on that spacecraft came from NASA in January, when NASA and Boeing revealed they were looking toward a May launch of an uncrewed test flight of Boeing's spacecraft, Starliner.

In a statement Wednesday, NASA said it "remains focused on continuous safe operations of the International Space Station and there is no change to the agency's support for ongoing in-orbit and crew return operations."

"Staffing levels for NASA personnel in Russia fluctuate based on operational demands," the statement reads. "The agency is in constant contact with U.S. Embassy Moscow and the Department of State regarding the presence of NASA personnel in-country."
