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.
Humans are used to being under constant gravitational pull on earth, and so Astronauts have to exercise in space, otherwise their bodies would atrophy in the zero-g environment. Otherwise they could not function properly when they return to earth.
When in space, the astronauts are experiencing weightlessness. The apparent lack of gravity causes your body's muscles to wither away and your bone density to decrease. To prevent this, they have to exercise.
When in space there is no gravity. The lack of gravity causes your body's muscles to wither away because they dont have to resist gravity. To prevent their muscles from withering away they have to exercise.
the microgravity makes there muscles very weak so they need to be very fit
they might be able to. that is not a very great question unless you are going into space
nothing is very stupid
their suits are very heavy.
Their bodies would become very weak.
The helmets are part of their space suits. They do not normally wear space suits unless they are going outside the spacecraft. Since there is no air outside and it can be very cold or hot. They need the suits to breathe and to protect them from the heat or cold and the vacuum of space which would kill them.
He make sure that his space probe was all good so that his other 2 astronauts (his friend) would be safety and that is because going outer space is very very dangerous.

Without gravity, food aromas waft away before making it to the nose. When you cannot smell very well you can't taste very well. And because of the fluid shifting to the head, astronauts' nose will be stuffy. Astronauts have to maintain a balanced and healthy diet that prevents them from losing weight.

No. Only a few astronauts have died in the line of duty, and very few (and no Americans) have died in space. The most dangerous part of any space journey is the launch and the landing. Three American astronauts were killed in a fire in the capsule on the launch pad during testing before Apollo 1. Seven astronauts were killed when space shuttle Challenger was destroyed during launch, and seven astronauts were killed when the shuttle Columbia disintegrated over Texas during re-entry. At least a few astronauts were killed in aircraft accidents. We believe that the Russians lost a couple of astronauts in space, but this has never been admitted. Several Russian astronauts have died during re-entry or during the landing.

No, we cannot breathe in space because the oxygen level is very low. astronauts have to carry oxygen tanks to space.
What Scientist do in Space?Scientist study things from outer space just like the sun,the moon,the planets,the Meteors,Comets,Asteroids.They also put Satelites outer space.Scientists are very useful to us they also tell what the weather is going to be
because it just is. deal with it. like jeez.
No astronaut has ever complained of boredom in space. NASA keeps the astronauts very busy during their valuable time in space. There is very little downtime in space.
It is difficult as it is very , very costly and quite dangerous there. And there will be people to protest the wasting of money and so on.
