Astronauts develop health problems when they spend a lot of time off Earth, such as cardiovascular disease and sleep, and scientists may have an idea why, when they published research indicating that mitochondria, the “power generation centers” of cells, may be responsible, as is often the case.Mice with eye and liver problems in studies had mitochondrial abnormalities, while NASA astronaut Scott Kelly may have found changes in the immune system aboard the International Space Station in 2015 also due to of mitochondrial problems.
According to “Engadget,” samples of body fluids taken from many other astronauts also support these claims that mitochondrial activity changed while in space.
The discovery came thanks to NASA’s open source platform, GeneLab, where the tool collects vast amounts of space biology data from around the world, including cell information, as well as DNA, RNA and proteins.
The findings reinforce fears that astronauts may face major health challenges in the future, especially for travel to the Moon and Mars.
Despite this, this discovery could be crucial to overcoming these problems, as study lead researcher Afshin Beheshti told NASA that this could lead to countermeasures and drugs that keep people well in space for long periods.
In the future it may be safe to spend months in orbit or traveling in deep space, and precautions may only need to be taken until you are within the relative safety of Earth.
