Imagine living in a place where everything floats, where there is no up or down, and where you can see 16 sunrises a day! This is the daily life of astronauts in the ISS, a giant laboratory orbiting Earth at 28,000 km/h.
Note:
Weightlessness or microgravity is a state where objects appear to have no weight. In the International Space Station, gravity is still present at 90% of Earth's gravity, but because the station is in a constant free fall around Earth, everything inside seems to float.
On Earth, you lie down in your bed. In space, it's very different! With almost no gravity, your body floats in all directions. You can't "fall out of bed," but it's also hard to stay in place!
To help them sleep well, the station's light changes color: blue in the morning to wake up the body, and red in the evening to signal it's time to sleep.
Did you know?
Astronauts sleep an average of 6 hours a night, a bit less than on Earth, because the noise from fans and the constant movement of the station sometimes wake them up.
Eating in space requires a lot of ingenuity. Nothing stays in place... everything floats! So, you have to find clever solutions to eat without making a mess.
Did you know?
Astronauts don't taste food as well in space because blood flows a bit more to the head and the nose gets slightly congested. So, they like spicy food!
Taking a normal shower is impossible in space: water would float everywhere and could damage equipment! Astronauts must find other ways to stay clean.
Did you know?
Water is so precious in space that it is almost 100% recycled: vapor, sweat, and even urine are purified to become drinking water. Nothing is wasted!
In space, the body weighs nothing. Muscles and bones no longer have to support the body's weight, and they weaken very quickly! To avoid becoming too weak, astronauts must exercise every day, about 2 hours a day.
Being an astronaut is a dream for adventurers and scientists alike! In space, everything you do on Earth becomes an incredible experience: you float, you fly, you see the Earth as a whole, and you are part of a team that explores for real.
Did you know?
When the rocket takes off, astronauts feel up to 3 times their weight due to acceleration. And a few minutes later, everything becomes lighter... they almost become birds!
Being an astronaut means learning to live without gravity, marveling at Earth, and discovering the secrets of the cosmos. Maybe one day, you too will see the stars... from up there ✨
Becoming an astronaut isn't just about putting on a helmet and getting into a rocket! You have to prepare like a true scientific and athletic adventurer.
Did you know?
Astronauts continue to train throughout their careers: each mission brings new experiences and discoveries.
So, if you love stars, challenges, and adventure, starting to learn science and staying fit is already the first step to becoming an astronaut. Who knows? Maybe soon you'll be floating above Earth too! 🌟
