Sunita Williams becomes the second astronaut to spend the longest time in space – see the astronauts who spent the most time aboard the ISS |

NASA astronauts have been the driving forces behind increasing human spaceflight by staying in space for lengthy durations to carry out essential analysis, aiding in mission objectives, and understanding extra about long-duration spaceflight. Let’s make clear the work and contributions of the astronauts who break information for being in space for the longest intervals.
They are representatives of the pinnacle of space exploration; spending years of their lives in space, and therefore, come to a complete understanding of long-duration space journey and the limits of NASA’s space applications.

Astronauts who broke information for longest space missions

Peggy Whitson – 675 days

Peggy Whitson is NASA’s longest-serving astronaut and has already logged 675 days in space. The whole quantity accounts for the work performed throughout three missions on the International Space Station (ISS) and one other 9 days in engaged on the Axiom-2 mission in 2023. With such a wealth of expertise, Whitson developed to develop into one in every of historical past’s most completed astronauts, being part of many NASA missions. Her management and expertise moved human exploration of the cosmos.

Sunita Williams – 606 days

Sunita Williams has spent 606 days in space. She will go down in historical past for her endurance. Her mission in 2024 Starliner was prolonged due to technical issues that added one other 284 days to her document. Williams has logged 4 space flights and took part in a few of the most necessary analysis and exploration missions on the ISS. Her work, notably in long-duration missions, locations her at the prime as a pioneer for NASA.

Jeff Williams – 534 days

Jeff Williams spent 534 days in space. His final long-duration space flight was in 2016 on Expedition 47, which he spent 172 days aboard at the ISS. One of his lengthy missions is an accumulation of 4 space missions. Assignment at the ISS concerned scientific experiments, servicing at the space station, and additional analysis into space expertise. The output of Williams has made him an indelible a part of operations at the space station by NASA.

Mark Vande Hei – 523 days

Mark Vande Hei spent 523 days in space, with the most necessary a part of this coming from a 355-day mission to the ISS between 2021 and 2022. That was a document for the longest single steady spaceflight by an American astronaut, damaged subsequently by Frank Rubio. This offered NASA with a singular set of knowledge on how the human organism holds up beneath spaceflight at these prolonged durations, that are completely important for missions planning to the Moon and ultimately Mars.

Scott Kelly – 520 days

Scott Kelly is finest recognized for his “One Year Mission” the place he spent 340 steady days aboard the ISS from 2015 to 2016. His mission was an necessary data-gathering expedition relating to the results of long-duration space flight on the human physique, and thus will present a precious useful resource in planning additional deep-space missions. His lifetime space time is 520 days. Kelly’s mission offered wealthy particulars about the organic and psychological issues astronauts face throughout long-duration space missions.

Barry “Butch” Wilmore – 462 days

Barry “Butch” Wilmore has spent 462 days in space. Much of his work on the ISS helped push the boundaries of understanding space journey. His prior missions, in addition to the Starliner mission in 2024, had been unexpectedly prolonged by technical delays, including days to his tally. Much of his mission operations and challenges of sustaining spacecraft had been mentioned.

Mike Barratt – 447 days

Physician-astronaut Mike Barratt flew on the ISS for 2 missions and gathered 447 days in space. Due to his medical background, he performed a serious position in researching human well being throughout long-duration spaceflights. The contributions of space drugs work by Barratt have been crucial to understanding the affect of long-duration space journey on the human physique and have ready astronauts for deeper space missions in the future.

Shane Kimbrough – 388 days

Shane Kimbrough flew for 388 days and added loads to the growth of the ISS. A 3-time veteran spaceflight astronaut, Kimbrough took half in quite a few spacewalks for station upgrading and servicing the ISS. His effort in direction of station upgrading was immense in sustaining the space station operational and selling the technological growth by NASA in space.

Michael Fincke – 382 days

Michael Fincke holds the document as one in every of the longest-serving astronauts in the historical past of NASA. His cumulative three separate missions made it to 382 days in space. His sequence of missions have contributed closely to analysis inside the ISS, corresponding to involvement with experiments and upkeep of techniques inside the ISS. Fincke’s work has performed an necessary half in NASA’s operational effectiveness inside its space applications, and he’s nonetheless an necessary a part of the story about space journey.
