Many of us have fantasized about the idea of exploring outer space, but the reality is far harsher than the movies make it seem. In order to survive the hostile environment of space, astronauts rely on spacesuits to provide the necessary air, water, pressure, and protection. But what would happen if someone found themselves without one of these vital suits?
Sci-fi films like “2001: A Space Odyssey” and “The Expanse” have depicted astronauts enduring and surviving brief exposures to space without a spacesuit, while others have shown graphic deaths. However, the real-life consequences are far more severe.
According to Stefaan de Mey, a senior strategy officer at the European Space Agency (ESA), the lack of oxygen in space would cause a person to lose consciousness within 10 to 15 seconds. The expansion of oxygen in the body would result in the rupture of the lungs, leading to the boiling and bubbling of blood, ultimately causing fatal embolism. Without the ability to breathe in space, the oxygen supply becomes a major issue.
To minimize the risk, individuals would need to empty their lungs as much as possible before entering space. The complete absence of pressure would also lead to other lethal problems. For example, bodily fluids, such as saliva and tears, would boil, and the human body would expand. However, the skin would remain elastic enough to withstand the pressure change, debunking the myth of exploding humans.
In the best-case scenario, a person would have only a few precious seconds before their oxygen supply is depleted, causing them to lose consciousness. Brain death would quickly follow unless the individual is promptly rescued and resuscitated in the safety of a pressurized spacecraft.
Apart from providing essential oxygen and pressurization, spacesuits also shield astronauts from other threats. Extreme temperatures ranging from minus 240 to 250 degrees Fahrenheit (minus 150 to 120 degrees Celsius) are experienced in low Earth orbit (LEO), posing risks of burning or freezing. Radiation is another hazard that spacesuits protect against. Prolonged exposure to solar radiation can result in radiation sickness and an increased risk of cancer, while UV light can cause skin burns. The added danger of micrometeoroids and space debris further emphasizes the importance of spacesuit’s multiple layers.
In conclusion, being in space without a spacesuit is a deadly proposition. Immediate unconsciousness due to oxygen deprivation, bodily damage caused by pressure changes, extreme temperatures, and radiation threats make survival impossible without the protection of a spacesuit. While the idea of space exploration is intriguing, it is crucial to acknowledge the immense challenges and risks it entails, emphasizing the significance of spacesuit technology in ensuring the safety and well-being of astronauts.
