00:00My name is Luca Parmitano and I'm an Italian astronaut with the European Space Agency and I'm your space correspondent.
00:10We are entering into the third month of my mission here on space.
00:15We have had a lot of interesting science and exciting science performed here on the space station.
00:21One of them is called fluid shift.
00:25What we know about the human body in microgravity is that our blood and all the fluids in our body tend to float toward the upper body because of the difference in the effect of the heart pumping in microgravity versus the earth.
00:44That fluid shift has many consequences.
00:48It increases the pressure in our eyes, it increases possibly the intercranial pressure, it changes our cardiovascular behavior.
00:56So this study is trying to figure out what changes and how to measure these changes that happen in our body.
01:06Together with that, I am personally undergoing an experiment for which I'm a subject called vascular aging.
01:12When we go back down to earth after a long permanence in space, our cardiovascular system has aged in a way that is inconsistent with the way it would have happened on the ground.
01:24We don't know what that is due to. It could be dieting, it could be our performance here in space is different when we move around, when we do sports.
01:33But this study is trying to figure it out and connect the dots.
01:38And finally, like I said, we are getting ready for a lot of exciting science.
01:42So stay tuned and I will talk to you soon.
01:45And finally that happened.
01:48Should we check that out?
01:49Would say what?
01:50I am not yet
