CTOnews.com, May 7 (Xinhua) Mars is the next target for human space exploration, but who will be the first human on Mars? Women may be better suited for this difficult task than men, according to a new study.

Back in the 1950s, the National Aeronautics and Space Administration (NASA) conducted a study that came to the surprising conclusion that women are better suited for space travel than men. Women tend to be smaller and lighter, and their reproductive systems are relatively less vulnerable to cosmic radiation. However, despite this knowledge, NASA decided in the 1960s to select only male astronauts.

In April, the European Space Agency (ESA) conducted a new study at the Astronaut Center in Cologne, which was published in the journal Natural Science report. The study further confirmed the validity of the original NASA report written in 1959 by General Donald Frickjinger and Dr. Wlandov Lovelace and recommended that NASA consider selecting all-female astronauts for long-term missions.

So far, only 76 women have been into space, less than 10% of all astronauts. But that is about to change. Half of the astronauts in NASA's Artemis program are women, and new research points out that "female astronauts will play an important role in future space exploration missions."

The study points out that women have many advantages over men: they weigh less and need less fuel to get into orbit; they consume less oxygen; they have a lower risk of heart disease; and, according to the results of the original NASA test, they are better tolerant of small spaces and long-term isolation.

The distance from Earth to Mars is about 140 million miles, the one-way flight time can be as long as seven months, and the payload per kilogram is crucial. Therefore, female astronauts with the same ability but eat less, consume less oxygen and weigh less may be the best choice.

The first woman in space was Valentina Tereshkova in 1963, and the most recent was Anna Zina, a Russian astronaut on the SpaceX Falcon mission in 2022. NASA has announced that a woman will be involved in the Artemis-3 mission, which is expected to land on the moon in 2025. ESA researchers say the next step should be to send all-female astronauts to Mars.
