Do astronauts lose their memory when weightless?
No.
Why skeleton of astronauts turn red in space?
I don't think that they do. However astronauts skeleton's do tend to lose some of their calcium while in space. This is because the lack of gravity means that the skeleton is not stressed. To try and prevent this calcium loss astronauts try and exercise hard (to stress the bones) if they are in space for a long period.
How do you lose bones as you grow?
You do not really 'lose' bones but some fuse together. Particularly the bones in the cranium.
What happens to bones in space?
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.
What happens to your bones when you are weightless?
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.
Why do astronauts lose muscle mass during space travel?

Why do astronauts need to do special exercises?
In space there is no gravity for the muscles to work against so they tend to degenerate as do the bones they are attached to. Astronauts special exercises help to minimise these problems.
How long can astronauts survive in space?
No one knows, but typically astronauts do not stay in space for more than 1 year. Otherwise, the zero gravity will degrade their bones and muscles
Do you form new bones as an adult?
No, you actually lose bones. These bones join together during childhood years.
How much bone density do astronauts lose per month while in space?
1% of their bone.
What problems can be caused by an astronauts bones getting thinner?
When an astronaut goes to space, the lack of gravity in the capsule or the space station will make his bones and joints very weak. A period of 2-hour exercise is required every day so that his bones will not shatter when he returns to Earth. Technically the astronauts' bones will not get thinner, but instead weaker. Problems like osteoporosis can be caused if the astronaut stays in space for extended periods of time.
Why do bones ache during old age?
You lose cartilage between the bones, so the bones rub against each other.
