The answer is an umbilical cord. It keeps astronauts from floating out into the universe.
No the astronauts wear their space suits when they are launched, but they remove them later.
They literally used Silly Putty.
The spacecraft that astronauts go up in, have their own life support systems which regulate conditions to keep the spacecraft hospitable.
The astronauts wear tethers whenever they exit the space station so that they remain attached to the station. Otherwise, without sufficient gravity to keep them close by, they could easily drift away into space.
i dont think usally since they useally try to keep the foood as fresh as possible in space
No the astronauts wear their space suits when they are launched, but they remove them later.
what astronauts do to keep their mouth healthy is to brush their teeth obviously (and what do suits have to do with your mouth) NOTHING!
To keep us from floating in to space.
To continue exploring space, carrying out experiments, and learning how to live in space.
gravity and oxygen
They literally used Silly Putty.
They only have their body heat to keep warm.The only heater they have is in their space gloves
They have oxygen tanks attachted to there backs which have pipes with masks on the end which the astronauts keep on there face.
The force that keep's us (or you) is the gravity.
They just keep floating around.
In a space station to keep warm you would use a space heater(heater) to keep warm. Space is cold so wearind heavy cloths would help.
There's no gravity in space - this affects their muscles. Exercising keep the muscles toned.
