RaginCajun, thanks for looking into that. You mentioned 437.7 days in space...was that in a single mission? What was the cosmonaut's condition upon his return to earth?Yes, that was a single mission. I have no idea what his condition was upon return but I will try to find that out also. I've only been here for 2 years so I'm still learning all of this "space stuff".

It helps but what I want to know is at what rate does an astronaut lose blood volume during space flight? I mean Stefanyshyn-Piper was only in space 12 days and NASA mentioned blood volume in her case. However, what happens to blood volume during a 6 month flight? That 10 to 14% volume loss information you found happens almost immediately upon entering space, and you don't get it all back until you return to gravity and recover. They haven't come up with an answer on how the gravity on earth actually stimulates muscle growth, but they know if you take out the gravity factor while trying to maintain muscle growth in space, it's never the same as being on earth...some kind of mechanical to chemical trigger the muscles receive when gravity is present!

| I spoke to several people today and none of them have ever heard of "losing blood volume". One of my buddies here has an older brother that was an astronaut and he had never heard of it either. Now everyone did say they heard of muscle and bone loss, which is why they don't like women to take long trips in space because they have bone loss when they get older anyway. Also, none of the people I spoke to knew anything about the Russian guy or how his extra long stay in space affected him. I hope this helps.

SMSB, you found the answer. One of those links you posted states that the body gets rid of some blood volume once the astronaut enters zero-g to compensate for excess fluid pressure in the upper body. Thanks!
