This week in Space emission, the pupils of the elementary school Pasteur in Montmorency take the microphone to ask all their questions relating to the behavior of the body of the astronauts in space. Once again, despite an already busy schedule on board the ISS, Thomas Pesquet took the time to answer them.
When you have to take precise measurements while remaining still and relaxed but weightlessness does not lend itself to the game … you take out the straps! Myotones experience@ESA on resting muscle tone. #straplife #MissionAlpha @Astro_Megan https://t.co/0erUtU5uG5 pic.twitter.com/AEbaHGayTE

Rachel, 8 years old, a big fan of the space mission, has a lot of questions about astronauts, but most of all, she really wants to know how the brain behaves in zero gravity.
You know, in zero gravity, the brain behaves almost the same as on Earth. But what happens is that when you arrive, it’s a new environment and you have to learn to use your body in a slightly different way: you have to learn to float, you have to learn how to move … Your brain learns to do these things.
Clara, 9 years old, addressed to Thomas Pesquet: “What do you feel in your body when you are in space?”. The astronaut replies that he felt a lot of things, especially at the start of the mission, but for him, what matters is that “we feel a lot of freedom”.
Oscar, 8 years old, this “visceral” question arises: “In weightlessness, do the organs move in your body?”.
The organs of the body cannot move all over the place, but they do move a little bit.
And finally, Camilya, 8 years old, ask this last question: “Is it true that we age faster in zero gravity?” The astronaut answers him: “We lose muscle mass, we lose bone mass, our arteries become a bit rigid. We have lots of small effects like that which are due to the fact that we are in space and in weightlessness, which look a lot like the symptoms of aging. It’s not aging, but it looks a lot like it. So we do a lot of scientific studies on ourselves to understand the mechanisms of aging. “
