Does an astronaut cry tears in space?
Astronauts can cry tears in space. Tears will not run down your face, because there is no gravity, but they don't need gravity to form. When the tears get big enough they will break free of the eye when you blink and will float around in space forever until they freeze.
What is the training astronauts go through?
Astronauts go through a great deal of training prior to going into space. It can take years for astronauts to go through all the training they need, which includes learning to work in zero gravity and going through a variety of realistic simulations.
Why do astronauts need rigorous exercise in space?
their suits are very heavy.
Do astronauts need to have a passport while in space?
No , but for astronauts visiting from other nations they do need passports to travel to the respective countries who are launching them into space e.g. the U.S. , Russia .
Why do Astronauts have to be very fit before going into space?
Why have scientists developed exercises for astronauts living in outer space for long periods of time? Due to lack of gravitational field all the systms of the body but especially the musculoskeletal system is affected, in terms of bone resorption. To mninimize the effects of zero gravity exercises are developed.
How do astronauts shower on the space shuttle?
need gravity and you wash off with a wet washcloth
Why do astronauts need exercise in space?
There's no gravity in space - this affects their muscles. Exercising keep the muscles toned.
What does a artificial limb have to do with space?
Artificial limbs, especially advanced prosthetics, are being developed for astronauts to use in space to help with mobility and dexterity in the microgravity environment. These artificial limbs need to be lightweight, durable, and functional to assist astronauts in performing tasks on spacecraft and during spacewalks.
How do astronauts have a bath?
in space there will be no microbial activity hence no need of bath for astronauts and there will be zero gravity in space and also it occupy hell lots of place to store it......... hence waste of money,time.and full nonsence
Will astronauts be able to survive in space without their specially made outfits if not why?
no because there is no air in space their is less gravity so need to wear special outfits
Why do astronauts need to do special exercises?
Astronauts need to do special exercises in space to prevent muscle and bone loss due to the lack of gravity. Without the effects of gravity on their bodies, muscles and bones can weaken and deteriorate over time. Special exercises help maintain their physical health during space missions and upon return to Earth.
Does an astronaut cry tears in space?
Astronauts can cry tears in space. Tears will not run down your face, because there is no gravity, but they don't need gravity to form. When the tears get big enough they will break free of the eye when you blink and will float around in space forever until they freeze.
When you come back from space do you have to learn how to walk?
Yes, astronauts need time to adjust to gravity upon returning from space. Referred to as "space adaptation syndrome," it can include issues with balance and muscle strength. Through rehabilitation and physical conditioning, astronauts gradually regain their ability to walk.
How will astronauts get oxygen out of space?
They need to take it with them. There is no oxygen in space
Why do you lose bone density in space?
In space, the lack of gravity-induced pressure on your bones leads to decreased bone density because your body does not need to support its weight in the same way as it does on Earth. As a result, astronauts in space experience bone loss due to reduced mechanical stress on their bones, which can lead to weakened bones and an increased risk of fractures.
What is the training astronauts go through?
Astronauts go through a great deal of training prior to going into space. It can take years for astronauts to go through all the training they need, which includes learning to work in zero gravity and going through a variety of realistic simulations.
Do astronauts need to know biology?
The depends. If they're researching the affects of zero gravity on biological tissues, then yes. If not, then they just need to know the effects that being in space will have on their own body, such as loss of bone mass.
