Mark Vande Hei: Breaking Records for Science

NASA astronaut Mark Vande Hei is returning to Earth after living in space for 355 days, the record for the longest single spaceflight by a NASA astronaut. This extended mission aboard the International Space Station provides researchers an opportunity to observe effects of long-duration spaceflight on the human body as the agency makes plans to return to the Moon under the Artemis program and prepare for human exploration at Mars. During his record-setting mission, Vande Hei spent many hours on scientific activities aboard the space station, conducting everything from plant research to physical sciences studies.
