NASA has even created a fun acronym for the issues: RIDGE, which stands for space radiation, isolation and confinement, distance from Earth, gravity fields, and hostile and closed environments. New research adds to the worries by describing how being in space destroys your blood. Or rather, something about space—and we don’t know what just yet—causes the human body to perform hemolysis at a higher rate than back on Earth.
