Astronauts wear this space suits as the body can not face the atmosphere when they walk outside the craft it could be to hot or to cold or the preasure is far to much for the body.

They don't; you can fly in a spacecraft in your shirtsleeves - as long as you don't lose cabin pressure! Of course, if you lose cabin pressure, you need a way to keep oxygen and warmth around you.

Where do astronauts come from?
Astronauts can come from various backgrounds, such as military pilots, engineers, scientists, and medical doctors. They are selected and trained by space agencies like NASA and ESA to prepare for missions to space. Applicants must meet rigorous physical, educational, and experiential requirements to become astronauts.
Why must a astronaut were a pressurized suit in space?
Astronauts wear pressurized suits in space to protect themselves from the vacuum of space, which has no air pressure. The suit provides a breathable atmosphere, regulates temperature, and maintains the necessary pressure for survival in the harsh conditions of space. It also shields astronauts from harmful radiation and micrometeoroids.
Why are space suits heavy?
Space suits contain many important gadgets and other things to keep the user alive. Also, they must be pressurized, and be easily movable, with protection from radiation. Besides, in space, they don't weigh anything.
Can astronauts breathe on the moon?
No, astronauts cannot breathe on the moon because there is no atmosphere. It lacks oxygen and air pressure required for humans to breathe. Astronauts must rely on oxygen supplies within their spacesuits or habitats.
How do astronauts keep their food fresh in space?
Astronauts use special packaging and processes to ensure food stays fresh in space. Foods are dehydrated, vacuum-sealed, or thermally stabilized to prevent spoilage. Refrigeration is not possible in space, so food must rely on other methods to stay fresh.
When astronauts travel in space they must wear special helmets. Why?
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.

Is there little air to breath on the moon at all?
There is not even a little air to breathe on the moon. There is no oxygen at all. This is why astronauts must wear space suits with self contained breathing equipment.

What must astronauts have to travel to space?
A rocket.

What would conditions be like on the moon for humans?
The Apollo 8 astronauts described the moon as very inhospitable. The moon has no way to support humans, Everything man needs to live must be carried with him when he goes into space, that includes the moon. The astronauts who walked on the moon could feel the cold in the lunar shadows. They also felt the heat of the sun through theid suits.
What is bad about space suits?
It must be having an itch. true and it must be heavy to wear

What is the effect of space vacuum pressure on astronauts during extravehicular activities?
The space vacuum pressure can cause a variety of effects on astronauts during extravehicular activities, including the potential for decompression sickness, known as "the bends," and the expansion of gases in the body which can lead to tissue damage. Additionally, the lack of atmospheric pressure can cause a rapid drop in body temperature and the potential for the lungs to collapse. Astronauts must wear specialized suits to protect themselves from these effects while working in the vacuum of space.
Can astronauts breathe on the moon?
No, astronauts cannot breathe on the moon because there is no atmosphere. It lacks oxygen and air pressure required for humans to breathe. Astronauts must rely on oxygen supplies within their spacesuits or habitats.
Why are switches in a space shuttle cockpit so big?
During the launch and re-entry of the Space Shuttle, the Astronauts must wear the large bulky gloves that are part of their space suits. The controls and switches are made larger so that they are easier to use while wearing those golves.
