Top 17 Things That Happen When You're in Outer Space

22 astronauts reported losing their nails after missions to the International Space Station. A study revealed that the specialized gloves they wear exert pressure on the nails, causing them to detach. This issue could potentially be resolved with a new glove design tailored for space travelers.

The human inner ear acts as an accelerometer: when we experience a change in motion, it helps prevent us from feeling sick. However, in space, this 'device' malfunctions. Astronauts have reported experiencing motion sickness for one or two days after arriving at the Space Station. Hopefully, this issue will be resolved if artificial gravity is successfully developed.

The absence of gravity causes a unique redistribution of bodily fluids. For instance, instead of flowing to the lower limbs as on Earth, blood moves upward toward the head. This explains why some astronauts appear 'puffier' when they return to Earth.

The heart undergoes significant changes in space. For example, it pumps less blood and becomes more spherical in shape. Research on astronauts not only helps prevent cardiovascular issues in space but also benefits people on Earth.

Astronauts must train consistently while in space. Muscle atrophy can weaken muscles and bones after extended space missions. As a result, all space travelers are required to engage in daily exercise routines.

Remember those sci-fi movies about people losing their mental stability aboard a spacecraft? It’s not entirely fiction. To prevent such psychological challenges, NASA and the Russian space agency 'Roscosmos' have conducted extensive research and continue to experiment to understand the effects of long-term space travel on astronauts.

If you’re wondering whether you could survive in open space if your spacesuit malfunctions, here’s what Mytour has discovered:

• You’ll lose consciousness within 15 seconds.
• This will be followed by suffocation or decompression.
• 10 seconds in open space can cause psychological instability and panic.
• Your lungs will collapse after 30 seconds.

In short, you wouldn’t survive for even a minute.

The microgravity environment has a profound impact on the human body in space. This is why scientists are increasingly researching ways to recreate it for astronauts, as it enhances their performance. Renowned physicist Stephen Hawking experienced this in 2007. 'Space, here I come,' he exclaimed after his zero-gravity journey.

Identical twins Scott and Mark Kelly became subjects of a study on 'the safety and performance of individual astronauts.' While Scott went to space, Mark remained on Earth. Both underwent identical medical tests. Scientists then compared the data, and the results were surprising. Scott’s C-reactive protein (CRP) levels, an indicator of inflammation, were notably high due to the stress he experienced during landing. The study is ongoing and could help us understand the changes the human body undergoes in space at a broader level.

Hypothetically, if a person falls into a black hole, they would experience extreme 'spaghettification.' Their perception of time would also alter. They might witness both the future and the past simultaneously. However, they would vanish instantly as their body and brain disintegrate into ions.

Being an astronaut is considered one of the most dangerous and challenging jobs in the world. A good sense of humor helps them cope with both physical and mental stress.

Space travel might be the most memorable experience for astronauts, but they all share a common longing for home and their loved ones.

Fortunately, astronauts haven’t harmed anyone, especially after spending extended periods in space, which can lead to both physical and mental changes. This Apollo Mission 10 photo serves as evidence of that.

If an astronaut drifts away from the space station due to a spacesuit malfunction or any other catastrophic event, things can turn grim quickly. Without rescue from the station crew, they would face the fate of floating in open space for 6 hours until their oxygen runs out. This is a terrifying prospect for any astronaut. However, NASA and other space agencies ensure astronauts have a chance to return safely using tools like EVA Rescue assistance.

Visual Impairment Intracranial Pressure (VIIP) syndrome is a vision deterioration condition reported by most astronauts after prolonged space missions. NASA has conducted research on this topic, but no specific cause has been identified yet. Mars missions may face challenges until scientists find ways to mitigate this syndrome for affected astronauts.

If you’ve ever wished to grow a few centimeters taller, a trip to space might temporarily fulfill that wish. The absence of gravity causes the human spine to stretch. A series of ultrasound tests have confirmed why astronauts return to Earth slightly taller.

In preparation for Mars missions, NASA scientists have studied the long-term effects of radiation on the human body. Mars' atmosphere is much weaker than Earth's, leaving astronauts less protected from cosmic radiation. The more we learn about shielding methods, the easier it will be for astronauts to safely explore Mars.
