SPACE causes the human body to destroy its own red blood cells and scientists don't know why.

A new study published in Nature Medicine found that space causes the human body to destroy red blood cells at a faster rate than on Earth.

The medical term for the destruction of red blood cells is hemolysis.

After a year, their red blood cell destruction was still found to be higher than in people who hadn't been to space.

Space is making human blood DESTROY itself and scientists are totally baffled
