It's called a space suit
The astronaut's space helmets allows them to breathe in space! It is connected to an air supply.An astronaut's space suit keeps him from harm from outer space objects!They live in an airtight environment (suit, ship, or station).
the suit of astronaut
The suit allows the person to walk in outer space, because the suit is designed to with stand the extreme heat and cold of outer space.
An astronaut needs a space suit that will allow him or her to stay safe in zero gravity. The astronaut also needs a camera that will record images from outer space.
their is no air on mars so if they do not have on a space suit they will die.
it has Scuba tanks of oxigen.
All parts of a space suit are important, if any part fails it can lead to the death of the astronaut.
A space suit, a really good spacecraft, and astronaut food.
Because space is a vacuum, there is no matter in it- no air, no oxygen, no water, etc. Therefore, the sun's temperature effects are very great upon the human body. A space suit provides oxygen for the astronaut to breathe, and it maintains an okay temperature for the astronaut.
He/she would suffocate and/or freeze.
If he took a monkey with him, presumably for scientific purposes, it would need to wear a suit just like the astronaut so it could breath and be protected from space.
