“Feminine” Cosmos: Myths, Physiology and New Reality

The concept of “feminine” cosmos has long existed at the intersection of political propaganda, gender stereotypes, and real physiological differences. Today, it is transforming, giving way to the concept of inclusive cosmonautics, where scientific data, not prejudices, play a key role.

Historical Breakthrough and Ideological Context

The first flight of a woman into space on June 16, 1963, was a triumph for the Soviet Union not so much in terms of humanism as in terms of ideology. The choice of Valentina Tereshkova was due not only to her outstanding parachute and physical qualities but also to her social origin — “a simple girl from a factory,” which perfectly fit into the narrative of Soviet equality of opportunities. However, her flight on “Vostok-6” revealed problems: discomfort with the spacesuit, poor tolerance of weightlessness, and difficulties with spacecraft control, which forced Korolev to declare: “I won’t let any more old maids into space.” For decades, cosmonautics returned to the “male” format.

Only in 1982, Svetlana Savitskaya went into space for the second time, and in 1984, she became the first woman to perform a spacewalk. Her preparation, like that of the first American Sally Ride (1983), was already devoid of showy ideology and based on strict professional criteria.

Physiological Aspects: Myths vs Data

For a long time, it was believed that the female body was less adapted to cosmic loads. However, modern research shows a more complex picture.

Ionizing Radiation. Tissues in the female breast and pelvic organs are considered more radiosensitive. Calculated risks of oncological diseases from cosmic radiation for women are 5-10% higher at the same dose of exposure. This is not a ban, but a parameter for planning mission duration and developing protection.

Bone-Muscle System. Women, on average, have lower bone mass and muscle strength, which theoretically increases the risk of osteoporosis and atrophy in weightlessness. However, individual differences outweigh average gender indicators. The decisive role is played by a strictly selected, individual program of physical exercises on trainers.

Cardiovascular System. In weightlessness, there is a redistribution of fluids to the head. Data from NASA indicate that women may be more susceptible to orthostatic instability (pressure problems upon returning to gravity), but the statistics are ambiguous.

Psychophysiology. Research on isolation experiments (Mars-500, SIRIUS) shows that mixed crews demonstrate better indicators of group cohesion and conflict resolution. Women often show higher resistance to monotony and better fine motor skills under stress conditions.

Paradoxical fact: according to NASA, women are, on average, more efficient than men in conditions of long-term space restriction and resource limitation. They have less body mass, consume fewer calories and oxygen, and produce less waste. This is a critically important resource argument for long-term lunar stations or Mars missions.

Contemporary: From “Firsts” to Systemic Participation

Today, gender parity in space is not a slogan but an engineering and management task.

Records and “firsts”.

Peggy Whitson (USA) — holder of the record for the total duration of stay in space among Americans (665 days) and the first woman commander of the ISS.

Cristina Koch (USA) — author of the longest solo space flight among women (328 days) and participant in the first fully female spacewalk in history (with Jessica Meir, 2019).

Yelena Serova — the first Russian woman cosmonaut on the ISS (2014).

Wang Yaping — the first Chinese woman cosmonaut (“taikonaut”) to perform a spacewalk.

Changing infrastructure. Space technology is becoming gender-neutral. Example: the development of the new xEMU NASA spacesuit, which is finally being created with the anthropometry of women (over 90 sizes compared to the outdated 5-6). This includes adjustments for the body, length of arms and legs, and the location of control elements.

Future: Reproduction, Motherhood, and Interplanetary Flights

The most complex questions of the “feminine” cosmos lie in the future.

Reproductive health. The question of the impact of weightlessness and radiation on fertility remains open. Animal experiments show the possibility of conception and embryonic development in microgravity, but data for humans are lacking. This is a key ethical and medical challenge for colonization.

Pregnancy and childbirth in space. Hypothetically possible, but associated with unexplored risks: the impact of radiation on the fetus, difficulties with adapting the child’s vestibular apparatus to gravity after birth, medical care. This is still the realm of science fiction, but already discussed by experts in bioethics.

Social-psychological climate. Forming stable mixed crews for flights lasting 2-3 years (Mars) is a new task for space psychology. The participation of women is recognized as necessary for long-term psychological stability of the crew.

Conclusion:

The era of the “feminine” cosmos as a separate phenomenon is coming to an end. Modern cosmonautics is moving towards an individualized approach, where the criterion is not gender, but specific psychophysiological indicators, professional competencies, and the ability of a specific person’s body to respond to challenges of extraterrestrial environments. Women cosmonauts have stopped being symbols, becoming full-fledged operators of complex systems, researchers, and key participants in the upcoming interplanetary expansion. Their presence is not a quota, but proof of the maturity of the space industry, which has learned to work with human diversity as a valuable resource, not as a problem.
