“A bird cannot fly with one wing only. Human space flight cannot develop any further without the active participation of women.” – Valentina Tereshkova

“If we want scientists and engineers in the future, we should be cultivating the girls as much as the boys.” – Sally Ride

“International cooperation is very necessary. Chinese have a saying, ‘When all the people collect the wood, you will make a great fire.’” – Liu Yang

As of Feb. 29, 2024, 75 women have flown in space. Of these, 47 have worked on the International Space Station as long-duration expedition crewmembers, as visitors on space shuttle assembly flights, as space flight participants, or as commercial astronauts. This article recognizes the significant accomplishments of these women from many nations as well as the pioneering women who preceded them into space. Many other women contributed to the assembly of the station and the research conducted aboard on a daily basis, including those on the ground who served as center directors, managers, flight directors, and in many other roles to pursue the exploration of space. Their achievements will contribute to NASA’s efforts to land the first woman and the first person of color on the Moon and possibly send the first crews to Mars in the coming decades.

Tereshkova, and Zhanna D. Yorkina, with an unidentified woman at far right. Right: Tereshkova just before boarding her Vostok 6 capsule for her historic spaceflight. 

The era of women in space began on June 16, 1963, when Soviet cosmonaut Valentina V. Tereshkova launched aboard the Vostok 6 spacecraft. Chosen from a group of five women selected for training, Tereshkova completed a three-day mission and entered the history books as the first woman to orbit the Earth. Nearly 20 years passed before another woman flew in space. In January 1978, NASA announced the selection of 35 new astronauts including six women for the space shuttle program. In response, the Soviet Union secretly selected a group of nine women cosmonauts in 1980. On Aug. 19, 1982, one of these women, Svetlana Y. Savitskaya, launched with her two crewmates aboard Soyuz T-7 for a week-long mission. The next day, they joined the two long-duration resident crewmembers aboard Salyut 7, marking the first time a space station hosted a mixed-gender crew. Ten months later, on June 18, 1983, astronaut Sally K. Ride made history as the first American woman in space, spending seven days aboard space shuttle Challenger during the STS-7 mission.

Savitskaya made history again on July 25, 1984, as the first woman to participate in a spacewalk during her second flight to Salyut 7. Less than three months later, on Oct. 11, Kathryn D. Sullivan completed the first spacewalk by an American woman from space shuttle Challenger during the STS-41G mission. With Ride as one of Sullivan’s crewmates, the flight marked the first time a space crew included two women.

Helen P. Sharman has the distinction as not only the first person from the United Kingdom in space but also the first woman to visit the Russian space station Mir. During her eight-day privately funded Juno mission in May 1991, Sharman conducted a series of life sciences experiments and talked to British schoolchildren. The next month marked the first time that a space crew included three women – NASA astronauts M. Rhea Seddon, Tamara E. Jernigan, and Millie E. Hughes-Fulford – during the STS-40 Spacelab Life Sciences 1 mission.

Selected in 1983 as one of the six members of the initial cadre of the Canadian Astronaut Program – later incorporated into the Canadian Space Agency (CSA) – Dr. Roberta L. Bondar became the first Canadian woman in space during the STS-42 flight of Discovery in January 1992. As a payload specialist and the first neurologist in space, she performed and participated in more than 40 experiments during the eight-day International Microgravity Laboratory-1 (IML-1) mission. NASA selected Dr. Mae C. Jemison as an astronaut in 1987. In September 1992, she became the first African American woman in space as a crew member of Endeavour’s STS-47 Spacelab-J mission. During the eight-day flight, she conducted numerous life and materials sciences experiments. Selected in NASA’s 1990 class of astronauts, Ellen Ochoa became the first Hispanic woman in space in April 1993 as a mission specialist on the STS-56 flight of Discovery, the second Atmospheric Laboratory for Applications and Science mission. An accomplished flautist, she played the flute during her spare time during the mission. Ochoa completed three more space shuttle flights and served as the first Hispanic director of NASA’s Johnson Space Center in Houston from 2013 to 2018. Selected in 1985 as an astronaut by the National Space Development Agency of Japan, now the Japan Aerospace Exploration Agency (JAXA), Dr. Chiaki Mukai became the first Japanese woman in space in July 1994 when she spent 15 days as a payload specialist on the STS-65 IML-2 mission aboard Columbia. She became the first Japanese astronaut to make two spaceflights when she returned to space in 1998 aboard STS-95.

The honor of the first woman to complete a long-duration mission belongs to Russian cosmonaut Elena V. Kondakova. She launched aboard Soyuz TM20 on Oct. 3, 1994, and spent 169 days aboard the space station Mir as a member of Expedition 17, returning to Earth on March 22, 1995. The first American woman to complete a long-duration mission, NASA astronaut Shannon W. Lucid, launched aboard space shuttle Atlantis on March 22, 1996, as part of the STS-76 crew. The second NASA astronaut to fly as part of the Shuttle-Mir Program, Lucid spent 188 days aboard Mir, setting a new record for the longest single flight by a woman, as a member of Expeditions 21 and 22, returning to Earth with STS-79 on Sep. 26.

With Lucid still onboard Mir, the August 1996 flight of Claudie André-Deshays, France’s first woman astronaut visiting the station during her Cassiopée research mission, marked the first time that two women lived aboard any space station. After marrying fellow French astronaut and Mir veteran Jean-Pierre Haigneré, she returned to space in October 2001, this time during her eight-day Andromède research mission to the International Space Station, becoming the first woman to live and work aboard two different space stations.

When on-orbit assembly of the International Space Station commenced in 1998, female astronauts took part from the very beginning. As the first woman to reach the new facility, NASA astronaut Nancy J. Currie participated in the first assembly mission, STS-88 in December 1998. She used the shuttle’s robotic arm to precisely join the American Unity Node 1 module to the Russian-built Zarya module, launched three weeks earlier.

The second space station assembly mission, STS-96 in May 1999, included three women on the crew – NASA astronauts Jernigan and Ellen Ochoa, and CSA’s Julie Payette. Jernigan became the first woman to participate in a spacewalk at the space station to install crane equipment for future assembly tasks, with Ochoa as the robotic arm operator. Payette became the first Canadian of any gender to visit the space station and became the first Canadian to return to the space station during STS-127 in 2009.

NASA astronaut Pamela A. Melroy served as the first female pilot on a shuttle flight to the space station, the STS-92 mission in October 2000 that added the Z1 truss, control moment gyros, and a Pressurized Mating Adapter to the growing station. She returned to the station as pilot of STS-112 in October 2002 and as commander of STS-120 in October 2007. NASA astronaut Susan J. Helms holds several distinctions for women. As a member of Expedition 2, she became the first woman to complete a long-duration mission on the space station, a 167-day flight between March and August of 2001. She had previously flown to the station during STS-101, making her the first woman to visit the facility twice. A graduate of the U.S. Air Force Academy’s first woman-inclusive class of 1980, Helms was the first woman with a military background to visit the station. She co-holds the record for the longest spacewalk to date, 8 hours 56 minutes, completed with her Expedition 2 crewmate NASA astronaut James S. Voss.

NASA astronaut Eileen M. Collins had already made history three times before, first in 1995 as the first female pilot of a space shuttle mission (STS-63), the second time in 1997 when she served as the first female shuttle pilot to dock with a space station (STS-84 and Mir), and again in 1999 as the first woman shuttle commander (STS-93). In 2005, Collins became the first woman to command a shuttle mission to the space station, the Return to Flight STS-114 mission, the first after the Columbia accident two years previously. NASA astronaut Heidemarie M. “Heidi” Stefanyshyn-Piper conducted the first spacewalk by a woman from the station’s Quest Joint Airlock on Sep. 12, 2006, during the STS-115 mission that installed the P3/P4 truss segment on the station.

On Sept. 18, 2006, Anousheh Ansari became the first Iranian-born American in space when she launched with her Expedition 14 crew mates aboard Soyuz TMA9. Flying as a spaceflight participant through a commercial agreement with the Russian government, Ansari conducted four experiments on behalf of the European Space Agency (ESA) during her nine-day mission. She returned to Earth with the Expedition 13 crew. Eighteen months later, through a joint agreement between the governments of Russia and the Republic of Korea, Yi So-yeon, a researcher at the Korean Aerospace Research Institute (KARI), became the first Korean in space when she launched aboard Soyuz TMA12 with her Expedition 15 crew mates on April 8, 2008. During her 10-day mission aboard the space station, Yi carried out 18 experiments for KARI. She returned to Earth with Expedition 16 crew members NASA astronaut Peggy A. Whitson and Roscosmos cosmonaut Yuri I. Malenchenko, enduring a strenuous ballistic reentry caused by a spacecraft malfunction. The event marked the first time that women outnumbered men during a spaceflight landing.

Whitson holds the distinction as the first female commander of the space station during Expedition 16 in 2007, her second long-duration mission to the orbiting lab. The busy expedition included the addition to the station of the Harmony Node 2 module, ESA’s Columbus research module, the first of the JAXA elements, and the arrival of the first of ESA’s Automated Transfer Vehicle cargo resupply vehicles. As noted above, Melroy commanded STS-120, the October 2007 mission that brought Columbus to the station, marking the first and only time that women commanded both the space station and the visiting space shuttle. In 2017, during Expedition 51 Whitson became the first woman to command the station for a second time. During this third flight, she spent 289 days in space, at the time the longest single flight by a woman. As of March 2024, Whitson holds the record for the most cumulative spaceflight time for a woman as well as for any American astronaut – o er the course of three long-duration missions aboard the space station, she spent a total of 675 days or about 1.8 years in space. She also holds the record for the most spacewalk time for a woman – during 10 spacewalks, she spent 60 hours, 21 minutes outside the station.

The first time four women flew aboard the space station at one time occurred between May 16 and 23, 2010. Expedition 23 Flight Engineer NASA astronaut Tracy C. Dyson had been living and working aboard since April when STS-131 arrived, with NASA astronauts Dorothy M. “Dottie” Metcalf-Lindenburger and Stephanie D. Wilson, and Naoko Yamazaki of JAXA as members of the shuttle crew – Yamazaki became the first Japanese woman to visit the space station. The mission brought four new research facilities to the station. Three weeks after the shuttle’s departure, Dyson and her crewmates welcomed a new trio of long-duration crew members including NASA astronaut Shannon Walker, making Expedition 24 the first to include two women. The next two-woman expedition took place between November 2014 and March 2015 – Expedition 42 included Roscosmos cosmonaut Elena O. Serova, the first Russian woman to make a long-duration flight aboard the space station, and Samantha Cristoforetti from Italy, the first female ESA astronaut on a long-duration mission, spending 199 days in space, a then-record as the longest by an international partner astronaut.

Serova, left, of Roscomos and European Space Agency astronaut Samantha Cristoforetti in the Automated Transfer Vehicle-5 Georges Lemaître cargo vehicle during Expedition 42.

Expedition crews including two women have recently become more common. During Expedition 57, NASA astronauts Serena M. Auñón-Chancellor and Anne C. McClain overlapped by about three weeks in December 2018. Between March and June 2019, McClain and NASA astronaut Christina H. Koch were aboard as part of Expedition 59, and NASA astronaut Jessica U. Meir joined Koch in September of that year during Expedition 61. Koch returned to Earth in February 2020, completing a flight of 329 days, the longest single mission to date by a woman.

The Expedition 61 crew conducted a record nine spacewalks between October 2019 and January 2020. Koch and Meir made history on Oct. 18 when they floated outside the space station to carry out the first all-woman spacewalk, one of several to replace the station’s batteries. The capsule communicator (capcom), the person in the Mission Control Center at NASA’s Johnson Space Center in Houston who communicates with the astronauts in space, for this historic spacewalk was three-time space shuttle veteran Wilson (who as noted above took part in the first four-woman gathering on the space station). “As much as it’s worth celebrating the first spacewalk with an all-female team, I think many of us are looking forward to it just being normal,” astronaut Dyson said during live coverage of the spacewalk. As if to prove her point, Koch and Meir conducted two more all-woman spacewalks in January 2020. Meir’s return to Earth marked the end of the longest period up to that time of a continuous female presence aboard the space station – 682 days (one year and 10 months) from June 8, 2018, to April 17, 2020.

The arrival of NASA astronaut Kathleen H. “Kate” Rubins on Oct 14, 2020, began the longest continuous period to date with at least one woman living and working aboard the space station. On Nov. 16, as a member of NASA’s Crew-1 mission aboard SpaceX’s Crew Dragon Resilience spacecraft, NASA astronaut Walker became the first woman to travel on a commercial crew vehicle. When she and her three crewmates joined the Expedition 64 crew abord the space station, they comprised the station’s first-ever seven-member resident crew. With Rubins already onboard, for the next five months two women once again called the space station home. NASA astronaut K. Megan McArthur, the first woman to pilot a commercial crew vehicle, arrived in April 2021 as a member of NASA’s Crew-2 mission, followed by Crew-3’s NASA astronaut Kayla S. Barron in November 2021.

In April 2022, when Crew Dragon Freedom lifted off, Crew-4 included first-time space flyer NASA astronaut Jessica A. Watkins and ESA’s Cristoforetti on her second long-duration flight, marking the first time two women flew aboard a commercial crew vehicle to the space station. Once they joined Expedition 67, Watkins became the first African American woman to join a long-duration crew. With Barron already aboard the station, this marked the first time three women on long-duration spaceflights lived and worked aboard the orbiting laboratory.

Right: Cristoforetti, left, and Watkins, right, bid farewell to NASA astronaut Kayla S. Barron wearing her SpaceX launch and entry suit as she prepares for her return to Earth with her fellow Crew-3 team mates.

In September 2022, Cristoforetti assumed command of the space station, a first for a European woman. When Crew-5 launched aboard Crew Dragon Endurance in October 2022, NASA astronaut Nicole A. Mann became the first Native American woman in space and the first woman to command a Crew Dragon mission, and Anna Y. Kikina of Roscosmos became the first Russian cosmonaut to fly aboard a U.S. commercial vehicle. For the second time, two women commanders, Cristoforetti and Mann, greeted each other as Crew-5 arrived to join Expedition 68. The launch of Crew-5 also marked the first time that five women lived and worked in space at the same time – the four women aboard the space station and Liu Yang aboard China’s Tiangong space station on her second space mission. The launch of Crew-6 in February 2023 marked the first all-male long-duration crew aboard a commercial crew vehicle. The return of Mann and Kikina marked the end of the longest time period with at least one woman living and working in space, 879 days, or 2 years and 5 months.

The hiatus in women in space lasted less than six months, during which two women on the Ax-2 mission spent eight days aboard the space station (see below). Renewing a female presence in space, NASA astronaut Jasmin Moghbeli arrived aboard the station in August 2023 as part of Crew-7. NASA astronaut Loral A. O’Hara joined her three weeks later when she arrived as part of the Soyuz MS-24 crew and they together conducted research as part of Expedition 70 as the only two Americans in space. On Nov. 21, 2023, they conducted an all-woman spacewalk, only the second pair of women to do so.

Right: O’Hara, left, and Moghbeli, right, prepare for their spacewalk as Roscosmos cosmonaut Nikolai A. Chub assists.

The presence of women in space will continue uninterrupted when NASA astronaut Jeannette J. Epps and her fellow Crew 8 crew mates launch to the space station on March 1 for an expected six-month mission. The March 21 launch of Soyuz MS-25 will mark a milestone in spaceflight history as the first time women will form the majority of a crew at launch. Roscosmos cosmonaut Oleg V. Novitskiy will command the flight, accompanied by NASA astronaut Dyson and the first citizen from Belarus to fly in space, Marina V. Vasilevskaya. Dyson, on her second long-duration flight, will remain aboard the station as part of Expedition 71 while Novitskiy and Vasilevskaya return to Earth after 12 days, accompanied by O’Hara who will have spent more than six months aboard the orbiting laboratory.

The story of women in space would not be complete without mention of the two women from the People’s Republic of China who have flown in space. China’s first female astronaut, Liu Yang, launched on June 16, 2012, aboard the Shenzhou-9 spacecraft with her two crewmates, docking with the Tiangong-1 experimental space station two days later. The trio returned to Earth after a 13-day mission. One year later, on June 11, 2013, Wang Yaping and her two crewmates launched aboard Shenzhou-10 for a 14-day visit to Tiangong-1. She conducted science experiments and taught a live physics lessons to school children from aboard the station. Wang returned to space on Oct. 15, 2021, aboard Shenzhou-13 as the first woman to live and work aboard the Tiangong China Space Station. She also conducted the first spacewalk by a Chinese woman. Liu completed her second flight, a six-month mission aboard Tiangong as a member of the Shenzhou-14 crew.

Women have been at the forefront of commercial spaceflights. In September 2021, two of the four crew members of the private space mission Inspiration4 were women – Sian H. Proctor, the first African American woman to pilot a spacecraft, and Hayley Arceneaux. They conducted science experiments during their three-day mission aboard the Crew Dragon Resilience spacecraft. The next month, Russian actress Yulia S. Peresild and her director spent 11 days aboard the space station filming scenes for a film entitled “The Challenge” that premiered in April 2023. The second Private Astronaut Mission to the space station, the May 2023 Ax-2 flight included a crew of four spending nine days aboard the orbiting laboratory conducting experiments. Making her fourth visit to the space station, former NASA astronaut Whitson and director of human spaceflight at Axiom Space commanded the Ax-2 flight, becoming the first woman commander of a private space mission. Two mission specialists from the Kingdom of Saudi Arabia’s inaugural astronaut program, including Rayyanah Barnawi, the first Saudi woman in space, served on the crew. Private astronaut missions to the space station represent precursors to privately funded commercial space stations as part of NASA’s efforts to develop a thriving low-Earth orbit ecosystem and marketplace.
