This three-person International Space Station crew mission saw the relaunch of the two crewmembers from the aborted Soyuz MS-10 flight six months prior. They were joined on this flight by NASA astronaut Christina Koch who, after launching for a six-month mission, ended up staying on the ISS for a year and breaking the longest single-spaceflight record for a woman by more than two months. Hazza Al Mansouri landed on this mission after launching on Soyuz MS-15. If you ask Russia and NASA what spaceflight number this was for Ovchinin and Hague, you'd get a different answer. Russia uses the internationally recognized Kármán line at 100 km as the marker of where space begins and NASA uses the US-only 80 km mark. Thus, on Soyuz MS-10, Russia does not consider Ovchinin and Hague to have reached space, but NASA does. This is either Hague's first or second spaceflight and Ovchinin second or third... depending on who you ask.
