French astronaut Sophie Adenot engaged in a live radio communication from the International Space Station (ISS) on March 19, 2026. Speaking with participants from the Space Louis Center for Educational Research, Adenot shared fascinating facts about daily life on the space station, the importance of multidisciplinary skills, and her perspectives on the future of space exploration.

Communication and Language in Space

During the radio event, Adenot highlighted the importance of language proficiency for aspiring astronauts. English serves as the primary language aboard the ISS, enabling seamless cooperation between international partners. Russian is also vital due to the significant Russian contributions to the station’s modules and operations. French and other languages may add value but are not mandatory. Adept communication among international teams underscores the collaborative spirit of space exploration.

Working as an Astronaut: Skills and Inspiration

Essential Skills for Astronauts

When asked about the skills needed to become an astronaut, Adenot stressed the importance of a broad knowledge base. "All subjects matter, especially those in science and technology," she explained. Beyond technical knowledge, qualities like teamwork, adaptability, and physical fitness also play crucial roles in astronaut training. The diversity of experiences and skills is what prepares astronauts for the unpredictable nature of their work.

Personal Inspiration

Adenot shared how her fascination with women adventurers and aviators shaped her dream of becoming an astronaut. Reading biographies of trailblazers, such as the first French female astronaut, deeply inspired her. These personal stories fueled her passion for exploration and encouraged her to pursue what once seemed like an impossible goal.

Scientific Research on the ISS

Medical Research

Adenot expressed her enthusiasm for the medical research conducted aboard the ISS, calling it her favorite area of study. The unique environment of space offers valuable insights into the workings of the human body. By understanding how the body responds to microgravity, astronauts and scientists can contribute to solutions for medical challenges on Earth.

Experiments and Daily Responsibilities

In response to questions about daily tasks, Adenot described how the crew performs various experiments, including cultivating plants. The research contributes to understanding resource sustainability for future missions and life on Earth.

The Challenges of Space Life

Dealing with Space Risks

Adenot addressed the dangers astronauts must prepare for in space. The three most alarming emergencies aboard the ISS are fires, depressurization (loss of air pressure due to structural damage), and toxic gas leaks. Astronauts undergo rigorous training to handle these situations, ensuring they are prepared for the worst.

Health Concerns

Upon returning to Earth, astronauts face significant health challenges, such as muscle and bone density loss. Adenot likened the recovery process to healing after a long illness but remained optimistic about the effectiveness of post-mission rehabilitation programs. While aboard the ISS, astronauts use specialized equipment, such as a weightlifting machine installed near a window with a view of Earth, to maintain their physical fitness.

Sleep Quality

Adenot also noted the difficulty of getting good-quality sleep in space. She advised limiting exposure to technology before bedtime to improve sleep, a practice that is just as applicable on the ISS as it is on Earth.

Looking to the Future

Preparing for Lunar Exploration

When asked about the next steps in space exploration, Adenot emphasized the need for well-designed spacesuits that allow mobility and endurance for extended periods on the lunar surface. Such advancements are crucial as NASA and international partners work towards establishing sustainable operations on the Moon.

The Ethical Question of Terraforming

Adenot responded thoughtfully to a question about changing the environments of other planets, such as terraforming. She expressed her belief that planets are beautiful in their natural state and should not be altered. However, she acknowledged this as her personal opinion, leaving the question open for future debate among scientists and ethicists.

Encouragement for Future Generations

Adenot encouraged young listeners to hold onto their dreams, no matter how impossible they may seem. She emphasized the importance of methodical preparation, reminding everyone that what once seemed unattainable can become a reality with persistence and effort.

Practical Takeaways

• Proficiency in English and Russian is crucial for working on the ISS. Aspiring astronauts should focus on building strong communication skills.
• Key skills for astronauts include scientific knowledge, physical fitness, teamwork, and adaptability.
• Health monitoring and recovery protocols are integral to long-term space missions.
• Ethical questions, like terraforming, will play a role in shaping the future of space exploration.
• Those interested in space careers should gain experience in STEM fields and participate in team-focused activities.
