How many women are in space right now and who are they?
As of today, the number of women in space is small on any given day, but it has grown steadily since the first woman orbited Earth in 1963. Today’s crews include astronauts and cosmonauts from NASA, Roscosmos, and partner agencies, serving as mission specialists, pilots, commanders, and flight engineers. Their roles span operating spacecraft, conducting science, and maintaining space stations. For current specifics, the active astronaut corps lists several women preparing for and executing long-duration missions on the International Space Station and beyond. This overview explains who is flying, what they do, and how their participation shapes the future of human spaceflight.
Defining "woman in space" and why it matters
A woman in space is any female astronaut or cosmonaut who crosses the Kármán line (100 km altitude) or qualifies by reaching the edge of space on a suborbital flight. This definition includes those who operate spacecraft in low Earth orbit and those who travel to the Moon or deep space. Representation matters because diverse crews bring broader problem-solving skills, operational resilience, and scientific perspectives. Tracking women in space helps clarify progress in inclusion, training access, and mission assignments. Understanding who is flying today also highlights how space programs have evolved from single pioneering flights to sustained, multinational presence.
How many women are in space on a typical day
On a typical day, the number of women in orbit ranges from roughly zero to a dozen, depending on mission schedules. Space station expeditions usually include one or two women, while short-term flights or visiting vehicles may add others. On days when no women are in orbit, participation continues through ground training, mission control, and research preparation. The table below summarizes recent, verifiable patterns for context rather than day-to-day fluctuations.
| Date or Period | Notable Woman Astronaut(s) or Cosmonaut(s) | Role / Mission | Agency | Why it matters |
|---|---|---|---|---|
| 1963 (Vostok 6) | Valentina Tereshkova | First woman in space (single flight) | USSR | Proved women could fly to space and return safely |
| 1982 (Soyuz T-7) | Svetlana Savitskaya | Second woman; first female spacewalker | USSR | Demonstrated EVA capability for women |
| 1995 (STS-63) | Eileen Collins | Pilot, later commander | NASA | First woman to pilot and later command a Space Shuttle |
| 2012 (Expedition 30/31) | Sunita Williams (long-duration) | Flight Engineer; ISS commander | NASA | Long-duration ISS command by a woman |
| 2019 (ISS Expedition 59/60/61) | Christina Koch, Jessica Meir | Flight Engineers; first all-female EVA | NASA | Historic all-female spacewalk; long-duration science |
| 2020 onward (SpaceX Crew Dragon) | NASA astronauts including women on commercial crew | Crew rotation to ISS via Commercial Crew | NASA / Commercial partners | Regular, sustained U.S. human spaceflight with women |
| 2023–present (ISS and future Moon missions) | International mix across NASA, Roscosmos, and international crews | Expedition crew roles, research, station maintenance | International | Sustained presence; more equitable participation over time |
Current presence in brief
- Typical ISS expeditions include at least one and often two women.
- Short-term flights and visiting vehicles regularly include women from multiple countries.
- Ground and training roles expand opportunities even when no woman is in orbit on a given day.
Roles women perform on orbit today
On modern missions, women serve across all critical functions. On the International Space Station, astronauts and cosmonauts operate robotic arms, conduct spacewalks, manage complex experiments, and command modules. In commercial crew flights, women serve as mission specialists and commanders, demonstrating parity with male counterparts. Beyond piloting and experiments, women lead station modules, coordinate scientific research, and communicate with schools and institutions on Earth. Their expanding presence across disciplines reflects that spaceflight tasks now require diverse skills rather than a narrow pilot profile.
Training pathways and barriers for women today
Training for spaceflight is demanding and broadly similar for men and women, focusing on spacecraft systems, EVA, survival skills, and long-duration physiology. Programs that once had few participants have gradually expanded access, though physical standards and course loads remain rigorous. Representation in science, technology, engineering, and mathematics (STEM) pipelines, along with outreach and scholarships, has increased the applicant pool. Institutional barriers have eased, but selection is still highly competitive. Programs increasingly evaluate candidates on skills, experience, and teamwork rather than gender, which supports sustainable, merit-based inclusion.
What woman-in-space activity looks like beyond low Earth orbit
Beyond the ISS, agencies plan lunar missions that include women as crew members. NASA’s Artemis program aims to land the first woman and first person of color on the Moon, with international and commercial partners contributing habitats and logistics. On longer deep-space journeys, mixed-gender, international crews are standard in mission planning to ensure operational effectiveness and psychological robustness. As destinations shift from low Earth orbit to cislunar space and Mars, women are expected to remain integral to crews, systems operations, and scientific leadership.
Impact on research and operational outcomes
Studies show that diverse crews, including gender diversity, correlate with stronger team performance and fewer risks in isolated, high-stakes environments. Women bring varied perspectives to life sciences, psychology, and human factors engineering, informing spacecraft design and protocols. Onboard research in microgravity benefits from broad participation, because physiological and cognitive studies include both sexes. This improves data quality and applicability for future long-duration missions. Grounded in evidence, space agencies continue to refine training, habitat design, and crew composition to maximize safety and mission success.
How to follow current woman-in-space activity
To track women in space today, consult official crew manifests from NASA, Roscosmos, and international agencies, which list names, roles, and mission timelines before launch and during flight. Live ISS tracking and mission pages show who is aboard and their assignments. Agency bios and profiles highlight individual preparation and objectives, while press kits explain experiment goals and timelines. For accurate, vetted information, rely on agency sources and major news partners that cite primary documents and official statements.
