NASA astronaut Mark Vande Hei reached a historic milestone this week, claiming the record for the longest single spaceflight of a U.S. astronaut.
Vande Hei arrived at the International Space Station on April 9, 2021, and is expected to return home on March 30, 2022, after spending 355 days in low-Earth orbit. This duration breaks the previous record for the most consecutive days in space by an American explorer, held by retired NASA astronaut Scott Kelly, by 15 days.
During his mission, Vande Hei has worked on hundreds of experiments and investigations to benefit life on Earth and expand NASA’s knowledge of how the human body adapts to long-term spaceflight. His contributions will help pave the way for more people to travel to space on longer-duration missions as NASA pushes the boundaries of exploration to the Moon and Mars.
Live coverage of the activities surrounding Vande Hei’s departure from the space station will air on NASA Television, the NASA app, and our official social media channels starting at 11:30 p.m. EDT on Tues., March 29. Coverage of the deorbit burn and landing of the Soyuz MS-19 spacecraft in Kazakhstan is expected to begin at 6:15 a.m. EDT on Wed., March 30.
