what are the major effects on body in zero gravity?

[sunofsky]

are there any such things are present in which the astronomer is getting trouble especially for his body in zero gravity. Though he is acquainted with the similar environment in the "practicing simulator on earth", but in actually space zero gravity, does the same person complaining any of outstanding trouble shooting?

their is tons of problems in zero gravity. The easiest way to think of "zero gravity" is that there is no such thing as "0". All you are doing is constantly falling. Now, thing of how you would feel if you fell off a cliff, and you NEVER reached the bottom....Theirs 0 gravity in a bottle. Of course if its an astronomer, we all know another major problem *cough*hubble*cough*. Our telescope lenses are ground on earth, taking in the effects of earths gravity. You take them to 0 gravity, they no longer have that pressure on them, and reform =p
If you really want to learn lots about z-g, go to this site,

Of course, i have to include this typo that i just saw on that page...

(NASA) - In order for astronauts to safely travel to Mars and other planets, new technologies must be developed to dope with the ill effects of space."
hehehe.... crazy Americans, always doping up their pilots...

well Buldric thanks for the link, your reply is marvelous one. I follow your suggestions.

just glad to be of assistance =D even if the reply was a tad bit late =p

Oh, Buldric awesome.

I am going to make one question, that the photo looking in your window is of your research, or observation, or it is just a photo of interest, or you capture it through your canon eos rebel xti (400D). just casually asking.

Sunil, my friend, zero gravity is bad news for the human body,
and 'simulators' on earth not come close. But more, outside the
magnetosphere, radiation is the real problem that no amount of
'simulation' can contend with. Cellular damage is inevitable without
a protective shield we have yet to develop, against the radiation
that permeates outer space. We also have to develop a gravity
technology that balances out the loss of gravity as we move further
from the earth, one that will keep our feet on the ground 'so to speak'.
Sunil, the effects due to zero gravity are cumulative on the body,
relative to ground level. Calcium in the bone is compromised along
with many other disorders.
We have solved many problems in our exploration of our deep oceans.
We will find a way in space.

Do you mean in my signature? Its a composite of photo's from....pretty much everywhere. Mostly from Nasa.

thanks nokton and buldric for the replies above.

how it would be amazing if the one part of earth become gravityless!! but it is not going to happen though.

My dear Sunil, stop the bus my friend, you are well outside known
physics now. But, one thing in my knowledge and experience.
Have knowledge of monks levitating and been blown about by the wind.
But feel you know of what I speak Sunil.....

Nokton, infact I was waiting for your reply very eagerly, and finally I got it, I understand what you quote. do you think that the less surface tension on any object to compel that object gravityless ! or in consideration of gravity the surface tension is not playing any role to grab the material properly.
