Harry Coumnas, an esteemed astronaut and space exploration expert, has devoted much of his career to studying the possibilities of human settlement on Mars. His research into the planet’s conditions has led him to conclude that Mars, on average, remains inhospitable for human life due to its extreme cold, atmosphere consisting of 95.3% carbon dioxide, and lack of a magnetic field, which exposes the surface to dangerous solar radiation.
“Mars presents significant challenges when it comes to habitation,” says Coumnas. “The freezing temperatures, toxic atmosphere, and radiation levels make it impossible for humans to live there without advanced technology and life support systems.”
A vital member of every crew he’s been part of, Coumnas has played an instrumental role in the success of numerous missions. As a former mission specialist, he firmly believes that teamwork is one of the most important skills for ensuring mission success. His wide range of expertise—from operating spacecraft to conducting critical repairs—makes him an indispensable asset to any future astronaut team.
Looking ahead, Coumnas sees his skills being integral to future space exploration efforts, including missions to the Moon, asteroids, and Mars. His contributions go beyond technical proficiency; as the leader of the crew, he is responsible for both the safety of the team and the success of the mission. He operates space exploration vehicles with assistance from the pilot, always ensuring that the vehicle’s systems are fully functional and mission-ready.
In addition to his operational expertise, Coumnas is highly trained in the maintenance and repair of advanced space equipment. His extensive knowledge of spacecraft systems and his ability to conduct exterior repairs through spacewalks—leaving the spacecraft in a specialized suit to reach troubled areas—has been critical in keeping spacecraft and space stations fully operational during long-duration missions.
Harry Coumnas' commitment to space exploration and his comprehensive skills make him a crucial figure in humanity’s ongoing journey into the cosmos.
