NASA has found that human health will not be affected by long-range space missions such as a visit to Mars, as the space agency feels comfortable sending people on long-range adventures after an in-depth study of the twin astronauts.
According to the British “Metro” site, US astronaut Scott Kelly spent nearly a year in orbit aboard the International Space Station while his twin brother Mark remained on the ground using data collected from both men before, during and after the 340-hour space mission. US scientists conducted 10 separate investigations.
The results of the investigations, published in the journal Science, review the impact of the longest space flight on humans, with many changes in Scott that did not occur to his brother. Some of these effects persisted after his time in space, but many of them are still in the next six months.
“Given that the majority of biological and human health variables remained stable or returned to normal after the 340-day space mission, these data indicate that human health can often be maintained during this space flight,” the study said.
The twinning study, which was 50 years old at the start of the study, gave scientists a unique opportunity to compare people with the same genetic material to different environments. Radiation exposure, low gravity, less exercise, limited diet and irregular sleep were among the potential risks. To spend time in space.
