Changes in Sławosz Uznański-Wiśniewski's body. Will he reveal details on tour?

• "IGNIS - Poland Reaches the Stars" is a nationwide tour undertaken by astronaut Dr. Sławosz Uznański-Wiśniewski
• There will be lectures and demonstrations of future technologies, question and answer sessions with the astronaut and the authors of the experiments.
• The tour will start on October 15 at the Warsaw University of Technology

Dr. Sławosz Uznański-Wiśniewski completed a pioneering research mission to the International Space Station (ISS) in July. In October, he will begin a two-month tour, "IGNIS - Poland Reaches the Stars," during which he will visit more than a dozen universities.

The IGNIS mission postflight tour is not only an opportunity to meet the astronaut and inspire them to choose a career path in the space sector, but also an opportunity for direct dialogue with the scientists and experiment creators of the IGNIS mission. There will be lectures and demonstrations of future technologies, question-and-answer sessions with the astronaut and experiment authors, as well as workshops and meetings demonstrating how science from orbit impacts everyday life and the development of modern industries in Poland.

Changes in the body after returning from space

As a reminder: On July 15, after 18 days on the International Space Station (ISS), the Ax-4 mission crew returned to Earth: Peggy Whitson (USA), Sławosz Uznański-Wiśniewski of Poland, Tibor Kapu of Hungary, and Shubhanshu Shukla of India. The Polish astronaut flew into space as part of the first Polish technological and scientific mission, IGNIS.

"During missions as short as IGNIS, the consequences of microgravity exposure are minor for well-prepared and healthy individuals. Astronauts who remain in orbit for longer periods inevitably experience muscle atrophy and bone loss. This means they are often unable to walk independently upon return to Earth, requiring long and intensive rehabilitation, " said Alessandro Alcibiade from the European Space Agency (ESA), flight surgeon for the IGNIS mission.

The doctor was responsible for preparing Sławosz Uznański-Wiśniewski for the flight to the International Space Station (ISS), monitored his health in orbit and was one of the first people present with him after his return to Earth.

Alcibiade also stated that changes in the human body that occur under the influence of space conditions are clearly visible to doctors and scientists. "And some are noticeable to everyone. Astronauts, especially at the beginning of a mission, have fuller, redder faces. This is a result of the flow of body fluids from the lower body in microgravity. Usually, the swelling, accompanied by dizziness and disorientation, subsides after a few days," the expert explained.

The effects of microgravity on the body are also visible in blood test results.

"There is no specific marker that would indicate a stay in space. However, astronauts usually have deficiencies in certain vitamins, such as B12 or D. This is related to limited access to fresh food and direct sunlight. Therefore, appropriate supplementation is used," noted Alessandro Alcibiade.

He added that similar research results were obtained by people who spent long periods of time, for example, at polar stations or in submarines.
