Why does an astronaut need a space suit?

Posted by Keshav Jain on


A space suit enables an astronaut to survive by providing him artificially with conditions like those he is used to on earth.



    These conditions can be reproduced in a large space craft or space station in orbit, but an astronaut still needs a space suit for operations outside the craft or for an emergency.



     In space men lack the air needed for breathing, the pressure required to stop their blood from boiling and the natural protection of the atmosphere against radiation. All these must be supplied by the space suit which also must withstand the cold of space.



     When an astronaut ventures into space, he leaves behind the safety of the atmospheric blanket which we, on earth, take for granted. His space suit becomes his own personal little world.
