One study analyzed the effects of space travel on the human body: the recovery rate is high and occurs in a relatively short period of time.
NASA is looking towards Mars with future missions in which it intends to send manned spacecraft, but it must first evaluate the effect of the red planet on the human body. Current forecasts take into account data from astronauts and space tourists.
A recent study analyzed the impact of a stay in space for four SpaceX tourists In 2021. The research enjoys cooperation with 100 institutions around the world.
The most obvious effects on the human body are a Significant increase in stress, exposure to increased radiation, and disorientation Caused by weightlessness. This is in addition to studies conducted a few decades ago that highlight problems such as bone loss, cardiovascular, visual, and kidney problems.
The study sample is large, totaling 700 people who have previously traveled to space. The four space tourists spent just three days and will help understand the impact of short periods.
the First results Published in the magazine nature It coincides with previous studies. People experienced changes in heart rate, skin, proteins, kidneys and other health indicators.
The study showed that most of the effects of space travel are temporary. he 95% of the affected health signs returned to their previous level Three months later.
Christopher Mason, a researcher at Weill Cornell Medical College, confirms that “The most in-depth examination we have ever done of a crew.” This study will help scientists understand which medications or rehabilitation methods are most effective when returning to Earth.
Getting to Mars is more accessible than ever
Inspiration4's mission is to prove that space is available to people who don't have an extraordinary physique and haven't spent years training for it. The SpaceX crew was an example of this.
The four astronauts underwent numerous medical examinations, from heart tests to skin biopsies. The most surprising data was Lengthening telomeres (the cap that protects the end of chromosomes) Upon reaching space.
Telomeres returned to their original length within a few months of returning, but they offer insight into the aging associated with space travel. These elements wear out with age and are associated with the appearance of signs of aging on the skin.
Changes in vital signs are important, but the study shows there is no reason why humans could not travel to Mars. The recovery rate upon return to Earth is high.
Radiation would be one of the biggest concerns. Study conducted on mice They analyzed exposure equivalent to two and a half years in space It indicates an association with permanent kidney damage.
“If we do not develop a way to protect the kidneys, an astronaut may reach Mars, but may need dialysis upon his return.”According to Keith Siu, a researcher who participated in the investigation.
a favour how do we work On the computer today.
