If reentry has to be delayed, due to adverse weather conditions or whatever, then they have to orbit again. Without Earth’s magnetic field and atmosphere to protect them from radiation, astronauts face radiation sickness, with symptoms such as nausea, vomiting, anorexia, and fatigue. 0000035487 00000 n He received a B.S. Indeed, the main difference between space and Earth is that in space there is almost no gravity, causing a feeling of weightlessness, resulting in the spacecraft or space station in which the astronaut is in to be in free fall toward the center of the Earth. NASA’s Twin Study took a deep look at the effects of space travel on the human body, even at the smallest levels. This process is similar to how human immune cells travel to areas with high blood flow, like the spleen and lymph nodes, to battle infection. Space radiation also increases the risks of cancer, damage to the central nervous system, and degenerative tissue diseases (such as cataracts and cardiac and circulatory diseases). In this video, we start off by using the road analogy to talk about the circulatory system. NASA found that space affects an aspect of DNA that is related to aging and cancer.
