Traveling to space is often seen as an eye-opening experience, providing a new perspective on humanity’s role in the universe. However, recent research has suggested that space travel could actually have a detrimental effect on cognitive abilities, making individuals slightly less intelligent.
The influx of travelers embarking on private space missions, led by companies like Blue Origin, has sparked scientific interest in how regular people respond to time spent in outer space. With billionaires and celebrities venturing into space, researchers are getting a unique opportunity to study the effects of space travel on non-astronauts.
A recent study conducted by the New York Times revealed the impact of space travel on individuals who spent a short amount of time in orbit during the 2021 Inspiration4 mission. The findings showed modest declines in cognitive function, stressed immune systems, and genetic changes in their cells. While most of these changes reverted to normal upon returning to Earth, it raised concerns about the long-term effects of space travel on the human body.
The study participants, including billionaire Jared Isaacman, doctor assistant Hayley Arceneaux, community college professor Sian Proctor, and engineer Christopher Sembroski, provided valuable data through samples of blood, urine, and cognitive assessments. The researchers discovered that kidney function was affected by space travel, increasing the likelihood of kidney stone formation. Additionally, genetic markers indicating age were altered, making individuals appear genetically younger in space.
Cognitive performance tests conducted on the astronauts revealed a decline in their ability to focus and maintain attention in space compared to when they were on the ground. This decline was attributed to distractions caused by the awe-inspiring views of space. Despite the limitations of the study’s sample size, findings like these are crucial as more people venture into space in the future.
Research of this nature will be essential for missions like NASA’s Artemis program, as it can help in developing signals and control manuals for individuals in orbit. Furthermore, it can influence the design of next-generation space stations to accommodate the needs of future space travelers. This ongoing research is vital for understanding the impact of space travel on cognitive function and overall well-being.
