How do astronauts cope without gravity?

Answer 1

They cope because an environment without gravity is still livable. Its not like gravity is oxygen. However without gravity certain chemicals are gone mainly because they arent able to condense in a gravity-free environment in which could cause minor problems.

Also, there is no up or down without gravity. Therefore it is a pain accessibility wise and also can cause more nausea than roller coasters.

Its a livable environment but its not a fun one.

Answer 2

They adjust.

For example, short term memory is affected in the first few weeks of an extended space mission. Once in zero g, astronauts for the first several days or weeks are unable to easily remember what they did the day before. (The mind equates zero g with sleep, and insists that waking activities are dreams...) Each individual adapts differently. Once adapted, memory is fine.

Their spines expand - sometimes upwards of an inch in height are gained.

Snoring almost entirely ceases in zero g because the soft palate does not droop like it does in 1 g.

They lose bone and muscle mass because the body thinks it no longer needs as much because of the lessened load.

Their faces get plumper because of the body's lessened ability to force fluid down the body.

Answer 3

They have to exercise a lot while in space to maintain muscle mass. Unfortunately there is no known way to maintain bone mass, so they just loose bone mass until they come back down. The longest anyone has been in space is a year. This is one of the barriers to a flight to Mars, because the round trip takes more than a year they would be in weightless space so long that they might loose too much bone mass.

Answer 4

Training

Answer 5

With no gravity you would fly endlessly; the gravity is just lowered.
Otherwise if they're working on space projects like satellites then they have a cord in their suit attached to the ship so they don't drift away.

Answer 6

when they are in 0G (zero gravity) they loose muscle mass because they aren't working hard to move (they primarily push of walls to go place to place). they have to train ALLOT to build muscle mass. when they are in the shuttle they have special work out equipment (i haven't looked but i guess they would be the same basic idea as elastic work out bands)even then they loose some muscle mass.

Answer 7

I expect they have a heap of fun, especially if they suffer from varicose veins - but it must be a pain having to anchor everything down. Oh well, such is life...

Answer 8

they can live perfectly
if they got to take a turd or a tinkle they use sucktion force to pull the .... waste out, same goes for garbage
their food doesn't have too much floating particles so no choking

Answer 9

I have no idea
All i know is that the moon has no gravity
