An astronaut got a blood clot in space —now our study shows how to best protect crew

The microgravity environment seems to develop a multitude of physical and physiological problems. Although, the joy of floating around like amoebas in a petri dish is overwhelming to astronauts, who would not love the rush of the feeling of the constant free fall. In Sci-Fi all the "advanced" space stations have the feeling of boring gravity where your feet are planted and you have to walk upright. The author claims that there are remedies for all that ails you in the astronaut core. A pill for all that troubles you. I have bills to pay. Is there a pill for that? So, when will we design space structures with gravity in mind? We need to bring with us food, water, shelter, gravity and purpose. Hey! We got four out of five. That can't be too bad? When we send astronauts off to Mars, how will they respond to an environment that is totally free of that free fall feeling? Some have informed me that the astronauts would be under the sun's gravity. Like Icarus, they would be falling towards the sun? How much mass would they have to be in order to be affected by the sun's gravity? Would zero gravity produce no motion in the ocean? After six months of travel towards Mars, would they be DOA? Has anyone done a computer simulation on this, and if not; why? We want to give sacrifice to the God Mars? Astronauts, you will be sacrificed for the good of all humanity. Your deaths will not be in vain; for it will be in space.
