NASA astronaut Mark Vande Hei arrived at the International Space Station on April 9, 2021, and will return home today (March 30, 2022), after spending 355 days in low-Earth orbit. This duration breaks the previous record, held by retired NASA astronaut Scott Kelly, by 15 days.
Vande Hei will return in a Soyuz spacecraft as scheduled alongside cosmonauts Pyotr Dubrov and Anton Shkaplerov.
While clocking the single longest spaceflight by a NASA astronaut, Vande Hei contributed to dozens of studies from the hundreds executed during his mission, including six science investigations supported by NASA’s Human Research Program, or HRP.
