Exploring the World of the Oldest Woman in Space

As of my last knowledge update in January 2022, the oldest woman in space is Dr. Peggy Whitson, an American astronaut who holds several records for her time in space. Here is an exploration of her remarkable journey:

Peggy Whitson:

  • Peggy Annette Whitson is a retired NASA astronaut who has made significant contributions to space exploration. Born on February 9, 1960, she hails from Beaconsfield, Iowa, USA.


  • Dr. Whitson embarked on three spaceflights during her career, all of which were aboard the International Space Station (ISS).

Expedition 5 (June 2002 to December 2002):

  • During her first mission, she served as a flight engineer on Expedition 5. This mission was notable for its scientific research, including experiments in various fields such as biology and physics.

Expedition 16 (October 2007 to April 2008):

  • Dr. Whitson returned to the ISS on Expedition 16, this time as the commander. She was the first woman to command the ISS and oversaw numerous experiments and operations.

Expedition 50/51 (November 2016 to September 2017):

  • On her third and final mission, she served as commander of Expedition 50 and Expedition 51, spending a record-breaking 288 days in space. This extended stay made her the oldest woman in space, as she was in her late 50s at the time.

Notable Achievements:

  • Peggy Whitson holds several records and distinctions in space exploration:
    • She is the first woman to command the International Space Station.
    • She has spent more cumulative time in space than any other American astronaut, with over 665 days.
    • Whitson is the world’s oldest woman to go to space, highlighting her resilience and dedication to space exploration.

Scientific Contributions:

  • Throughout her missions, Dr. Whitson conducted numerous experiments and research in fields such as biology, microbiology, and physics. Her work has contributed significantly to our understanding of how the human body reacts to long-duration spaceflights.


  • Peggy Whitson retired from NASA in 2018, leaving behind a legacy of remarkable achievements and leadership in space exploration.

Please note that developments may have occurred since my last knowledge update in January 2022, and there may have been new records set or other women who have since ventured into space. Peggy Whitson’s achievements, however, remain an integral part of the history of human space exploration.
