They would have spend some time readjusting to Earth and in many cases doing medical checks to see what condition they were in after their time in space.
Just like on earth, it comes down. Most astronauts entertained themselves by throwing things on the moon. They found out that things fly much further on the moon due to the lower gravity. However, the astronauts could not throw things as far because their suits were very constrictive.
Gravity depends largely on mass, the bigger the planet the greater the gravity should be
Their bones, heart, and muscles begin to waste away because they cannot strengthen themselves by working against Earth's gravity; if they return from over 8 months in space, their bones would instantly break. It's not a pretty picture.
What happens to your bones when you are weightless, is that your bones will get weaker and weaker. That is why everyday, astronauts, have to spend two hours on a treadmill everyday of there space expedition.
In weightlessness people lose about 1 to 2 percent of bone mass each month. This loss is largely in the lower bones -- the lumbar vertebrae and the leg bones.
Astronauts' muscles atrophy in space due to the decreased work they do without Earth's gravity.
Gravity Happens was created on 2011-05-19.
Astronauts do not completely leave the earth's gravity, they only enter a state of free fall orbiting the earth causing weightlessness. The astronauts that went to the moon technically do not leave the earth's gravity, they simply get close enough that the moon's gravity has a stronger effect than that of the earth's gravity. The distance at which this happens is called the sphere of influence. The moon's sphere of influence is approximately 66 000 km, this would be about 315 000 km away. In the Sun earth system, the earth's sphere of influence is 925 000 km. Therefore if you are within 919 000 km of the earth's surface, it's gravity will be the primary gravitational force experienced. The only exception is if you come within 64 500 km of the moon's surface.
they weaken Because there is no gravity in space muscles go unused. Because of the lack of use they weaken and even begin to deteriorate. Astronauts must exercise for hours daily in order to maintain there strength.
They weaken
Just like on earth, it comes down. Most astronauts entertained themselves by throwing things on the moon. They found out that things fly much further on the moon due to the lower gravity. However, the astronauts could not throw things as far because their suits were very constrictive.
the gravity increases
They die and their heads get crushed from pressure.
Nothing. Gravity exists in vacuum as well.
it's gravity increases
there sweat starts to float in the space shuttle because once the astronauts are exercising in space they would start to sweat
Their bodies would become very weak.
