Astronauts from SpaceX's tour groups contribute to scientific research on the effects of space travel on the human body
In a groundbreaking study published in the prestigious journal, Nature, researchers have shed light on the impact of space travel on the human body, particularly for space tourists. Led by Christopher Mason of Weill Cornell Medicine, the study compared data from the four American tourists aboard the Inspiration4 mission with that of 64 astronauts.
The Inspiration4 mission, a three-day space flight, marked a significant milestone in the new era of space exploration, with companies like SpaceX and Blue Origin leading the charge. This era includes ventures to Mars and the Moon.
During space travel, the human body undergoes various changes. The study revealed alterations in health indicators such as blood, heart, skin, proteins, kidneys, genes, mitochondria, telomeres, cytokines, and more. However, a promising finding emerged: approximately 95% of these biomarkers returned to their normal levels within three months after the space flight.
While the majority of changes reversed, the study raises intriguing questions about the long-term effects of space travel on human health. Researchers are particularly interested in understanding how microgravity and space radiation impact physiological systems, immune responses, and aging processes. Additional research is necessary to fully elucidate potential health risks and develop effective medical countermeasures.
The findings from the Inspiration4 mission have garnered attention from over 100 institutions worldwide, including The Washington Post, which has reported on this research. The study suggests that our bodies undergo various changes during space travel, most of which return to normal within a few months of returning to Earth.
As space tourism becomes more accessible, understanding the impact of space travel on the human body is crucial. The findings from the Inspiration4 mission provide valuable insights that can help scientists protect both space tourists and professional astronauts. The journey to understanding the full extent of space travel's impact continues, with the ultimate goal of ensuring the health and safety of all space explorers.
