Not all human bodies are prepared to travel in space. The warning was given by CNN in a report in which studies carried out in terms of aerospace medicine in the country are discussed, where the impact of weightlessness on the body is studied.
Ever since Neil Armstrong appeared on television right and spoke, from the moon, to an audience of over 530 million people across the planet that many aspire to do the same, while others have been intrigued by how the Apollo 11 mission managed to handle gravitational forces in the lunar environment.
The growing space exploration has led the medical community to investigate a new problem: the fact that the human organism is not prepared for weightlessness and this has health implications.
More than 50 years after this first trip to the moon, visits to space have become recurrent and will happen with increasing frequency. The most recent astrotourism flight took place on June 4th. This was the fifth time the New Shepard capsule had transported humans, and the team had five men and one woman.
The moon has one sixth of Earth’s gravity. This gravitational difference felt between the planet Earth and the natural satellite has an impact on astronauts and will, in the future, on astrotourists. The differences between the two gravitational forces are felt mainly in the heart, brain and muscles. The heart rate also drops significantly.
And there is still a “stretching” of the spine proven by NASA that came to compare the physiology of two twin brothers, one astronaut and the other not. Scott Kelly spent 340 days on the international space station while his identical twin, Mark Kelly, stayed on Earth. According to the US aerospace agency, Scott returned five centimeters taller than his brother. However, there was a decline in bone formation from Scott. There was still a slight Decreased cognitive abilities of Scott that it became slower and less accurate in its brain performance.
In Portugal, neurosurgery specialist Edison Oliveira and doctor Thais Russomano founded the first Center for the Study of Aerospace Medicine (CEMA) in the country, at the Faculty of Medicine of the University of Lisbon. Both also created the discipline of aerospace medicine, which is taught in partnership with the Portuguese Air Force, so that all questions about aeronautics are clarified. The bad news is that it only has 25 vacancies per year.
