This week, news outlets reported that the head of Russia's Space Agency threatened to leave American astronaut Mark Vande Hei — the record-holder for the longest spaceflight — aboard the International Space Station (ISS) rather than allowing him to return to Earth on a Russian spacecraft. It turns out that the threat isn't true, Ars Technica reported.

Vande Hei began his mission on April 9, 2021, and is scheduled to return to Earth on March 30, 2022, meaning he will have spent 355 consecutive days in Earth orbit, according to NASA. The plan is for Vande Hei to land in Kazakhstan along with two Russian cosmonauts, Flight Engineer Pyotr Dubrov and Commander Anton Shkaplerov, aboard the Soyuz MS-19 crew ship, a Russian vessel.
