Long time space missions could be dangerous for human life


The mice showed increased fat storage  as well as a loss of retinol, an animal form of Vitamin A. Potential early indicators for the beginnings of fibrosis, which can be one of the more progressive consequences of NAFLD were observed. “If a mouse is showing nascent signs of fibrosis without a change in diet after 13.5 days, what is happening to the humans?” Karen Jonscher, an associate professor of anesthesiology and a physicist at the University of Colorado’s Anschutz Medical Campus asks. Referring to humans, researchers also know about a loss of bone and muscle mass, as well as changes in vision and brain function in people, that spaceflight can cause. It’s proved that microgravity plays a role in liver damage. More, astronauts often returned with diabetes-like symptoms which however usually resolved quickly. If such things can’t be stopped or at least influenced, long time space missions could be dangerous for human life.
