Question

Quizplus · Accepted Answer

During liftoff, astronauts experience high levels of acceleration, which can cause blood to be pushed downwards, away from the brain. This can result in a decrease in blood flow and oxygen to the brain, which can cause temporary loss of vision or consciousness. It is important for astronauts to undergo training and wear special suits to help mitigate the effects of this phenomenon, known as orthostatic intolerance.
