The strange phenomenon that astronauts encounter when hovering in outer space
Checking the health of the astronauts, NASA discovered the phenomenon of 'blood flowing in the opposite direction' when the blood of astronauts flowed in the opposite direction to normal people. Doctors warn this phenomenon ...
When the astronauts were scanned for health checks before performing missions in space, NASA doctors detected blood clots in an astronaut's blood vessels. This surprises the doctors.
'We have never encountered this case, nor do we expect to see a phenomenon outside of our studies , ' NASA scientist Karina Marshall-Goebel told The Atlantic.
The astronaut did not have blood clotting symptoms, but because of this strange phenomenon, he had to use blood thinners during the mission.
The phenomenon of 'reverse blood flow' is a new danger for humans in outer space. However, things have not stopped there. NASA doctors performed ultrasound neck veins (vena cava) for 11 astronauts working on the International Space Station.
Blood flow in the neck veins of 5 of 11 people has stalled, does not flow continuously, even back and forth motion in the veins. Blood stasis in the veins is extremely rare, only a few cases of vein clogged legs after long flights.
The neck vein is very important, it connects the head and the heart, helps to transfer oxygenated blood from the head to the heart, helps reduce pressure in the brain. Therefore, stagnant blood that leads to blood clotting can cause lung damage, even life-threatening.

2 of the astronauts also have a strange phenomenon when blood flows from the heart to the head . Doctors call this 'extremely unusual phenomenon' . They think the blood has reversed because of a blockage. However, this phenomenon completely ceases when they return to Earth.
Although not affecting health, doctors still warn that this phenomenon is extremely dangerous.'However, it is good to discover this early, the monitoring and prevention of this symptom will be focused on our research immediately,' concluded Dr. Karina.
NASA currently plans to open a tour to the International Space Station in 2020, but to join you need to 'spare' about 39 million pounds (over 1 trillion VND).
