Vasilis Mavratsas, a Cypriot doctor specialising in Space Medicine, recently braved the harsh conditions of the Antarctic and South Pole for two months, with temperatures plummeting to -30°C. His mission involved delivering medical care in one of the planet’s most extreme environments, an experience that has brought him closer to his childhood aspiration of becoming an astronaut.

From Cyprus to the Cold
At just 32 years old, Mavratsas has already made significant strides in his medical career. Born in Larnaca and raised in Nicosia, he developed a fascination with space early on, inspired by tales from his mother about the Moon landing. He recalls a defining moment before undergoing surgery at the age of four when he told a nurse, “I want to be an astronaut.”

After moving to Texas to further his education, Mavratsas pursued his dream with encouragement from his family. He initially studied Chemistry at Rice University before transitioning to medicine at The University of Texas Medical Branch (UTMB). Now in his fourth year of residency, he has completed two years in General Pathology and is on the verge of finishing his specialisation in Space Medicine.
Training in Extreme Conditions
As part of his training, Mavratsas participated in the US Antarctic programme, working at both McMurdo and South Pole Stations. He describes the experience as both challenging and rewarding. “During our summer visit, we had 24-hour daylight,” he explained. Living in dormitories with fellow researchers, Mavratsas faced unique hardships, including meals consisting of food that had been frozen for up to 20 years.
“What I missed the most was fresh salads and fruit,” he shared. Despite the limited variety, the experience of living and working in such a remote location was exhilarating. With temperatures ranging from -5 to 3°C at McMurdo, and dropping to between -20 and -30°C at the South Pole, Mavratsas and his colleagues were equipped with thick clothing and adequate gear for outdoor excursions.
The Wonders of Antarctica
Mavratsas found the Antarctic landscape breathtaking. “In just 15 minutes outside, you could feel the moisture on your nose turning to ice,” he remarked. The sight of seals and penguins up close added to the adventure, which he described as a once-in-a-lifetime experience. At the South Pole, he noted the vast, snow-covered expanse, referring to it as the “End of the World.”
“It’s a flat, snow-covered desert. I visited an area called ‘The End of the World.’ It’s hard to describe—it’s just white as far as the eye can see,” he recalled, highlighting the stark beauty of the region.
Insight into Space Medicine
Mavratsas’s work in Antarctica is closely related to the challenges faced by astronauts in space. He elaborated on the critical role of space doctors, who are responsible for monitoring astronauts’ health throughout their missions. “Today, missions on the International Space Station last between 6 to 12 months. During these missions, space doctors conduct tele-sessions to monitor astronauts’ health remotely,” he explained.
The human body undergoes significant changes in space, including issues such as Space Motion Sickness (SMS) and muscle atrophy due to the lack of gravity. “Bodily fluids shift upwards, causing congestion and swelling, which is why astronauts must exercise for two hours every day,” he noted. This preparation is crucial for maintaining their health during and after missions.
Continuing Care Post-Mission
Mavratsas pointed out that medical care for astronauts doesn’t end upon their return to Earth. “Most astronauts return with low blood pressure and sometimes faint,” he explained, underscoring the importance of ongoing medical oversight. He also dispelled common myths about astronauts’ diets, clarifying that they enjoy a varied menu in space, although this is set to evolve as missions extend to the Moon and Mars.
As he prepares to complete his residency, Mavratsas looks forward to integrating his experiences from the Antarctic into his practice in Space Medicine. His journey is not only a testament to his resilience but also a reminder of the human spirit’s unyielding pursuit of exploration.
