Russia has confirmed that it will not leave an American astronaut stranded on the International Space Station.

Rumors that Russia might abandon astronauts on the space station started when Russian state media posted a trollish video on Telegram, made by Roscosmos according to NASA Watch, depicting the Russians abandoning the International Space Station and leaving it to de-orbit because Russia controls critical propulsion systems. As part of that video, the Russian astronauts can be seen saying goodbye to American astronaut Mark Vande Hei and leaving him behind. Vande Hei has spent more than 300 days in space, an ongoing world record.
