NASA’s Artificial Gravity Experiments May Help With Health Issues For Astronauts

NASA It explores how artificial gravity protects against the harmful effects of space travel on the health of astronauts. Humans, and all species on Earth, have evolved to thrive beneath the surrounding environment on this planet, with gravity being an important component. Every second of human existence, the circulatory system, digestive system, and central nervous system depend on the downward flow of fluids due to gravity. The muscles and bones It also maintains a basic level of strength and stamina by simply repelling the earth’s natural gravity.

When traveling to the Moon, Mars, and other planets in space, astronauts will have to endure extreme conditions, which can lead to serious medical problems. Even during their stay on the International Space Station, astronauts’ faces swell, their vision becomes blurry, their heart weakens, and they lose muscle and bone mass. Thus, they are required to engage in strenuous physical activity for several hours each day while in space, and are still at risk of long-term health problems even after they return to Earth. Astronauts aboard the International Space Station Exercising for up to 2.5 hours every day and eating a healthy diet to counteract the effects of microgravity.

NASA It investigated how the non-human species used in the laboratory were affected by the effects of space, including changes in gravity, radiation, and more. Drosophila is ideal for this study because its cellular and molecular processes overlap significantly with humans. The insects were flown to the International Space Station, where they were tested in a device that can hold flies at different levels of gravity. One group was subjected to weightlessness conditions in low Earth orbit, while the other group experienced artificial gravity caused by the centrifugation of the container. A third group remained on the ground as a control group.

Effects of artificial gravity on the nervous system

according to cell reportsAfter three weeks in space, fruit flies were back to earth To perform a comprehensive examination, including cellular changes in their brains, gene expression and the effect of aging. Both groups of space-faring flies showed symptoms of altered metabolism, cellular oxidative stress, and severe neurological effects. However, those preserved in artificial gravity appear to be protected from some neuronal abnormalities, including neuronal loss, glial cell number changes, oxidative damage and cell death.

The use of artificial gravity can temporarily reduce the challenging effects of microgravity on the nervous system of the fruit fly. Since fruit flies and humans are completely different creatures, despite their genetic similarities, these results cannot directly speak to what humans will experience over the course of their lives in space. However, it still paves the way for future research on protecting astronauts traveling to destinations with varying levels of gravity. NASA Scientists believe that artificial gravity could be the answer to safe, long-range space missions. Dr Janani Iyer, author of the study, stated,We are back again To the moon and then to MarsReducing the harmful effects of microgravity will be key to maintaining the safety of future explorers. This study is a step in the right direction to explore the protective effects of artificial gravity in space and to understand adaptation to Earth conditions after returning from space.”
