New mortal danger of flying to Mars


An international team of scientists has discovered the deadly danger of long space flights to the health of astronauts. It has been turned out that microgravity causes  malfunction in the internal jugular vein. This can be a significant problem for a manned mission to Mars. This is reported by Science Alert.

Specialists examined 11 astronauts who visited the ISS. It turned out that after 50 days in zero gravity in the jugular vein there were stagnation and reverse blood flow. One of the crew members was diagnosed with thrombosis or blockage of a vein, which was first observed during a space flight. Until the end of the mission, the astronaut was forced to be treated with anticoagulants.
