Some Problems and Risk Factors That Are Encountered by Astronauts and Cosmonauts in Space
Outer space can be dangerous, and there are certain things that should be considered by the Astronauts and Cosmonauts upon going into the outer space. These are the risk that they might get encountered into the outer space upon their explorations. These risks could endanger them as far as their safety and health is concern.
The weightlessness is among of the things to be considered. Usually we are affected with the gravity of the earth when we are in the force of the gravity. The force of the gravity or the pull of the earth is about 1g (g stands for gravity); this condition is different in the outer space.
The humans in space are said to be lighter in weight as feathers. This condition is due to the state of zero gravity resulting to the weightlessness. In space you will drift around and it is hard to do your usual activities; such as even as simple as drinking water from a glass or eating the usual foods you eat. The water from the glass will not pour unto your mouth and the foods could drift out from your hands because of the absence of gravity.
Man in space deals with these problems by providing their cabins with lines. With these lines, humans can be able to pull their selves towards the direction they want to go. They are also trained to live in a weightless condition before going into space mission. Astronauts or Cosmonauts usually have their especial physical exercise in order for them to keep in good health, thus avoiding possible damage of the heart, the blood vessels as well as their muscles because of the weightlessness condition.
Another consideration is the space sickness. Due to the motion of the spacecraft there are tendency that humans inside it could suffer from so called space sickness.
Life support is also a thing to consider. There is no oxygen in the outer space making it hard or impossible to breathe, unlike in the earth’s environment. Due to this situation, scientist developed a life support system that will support breathing as well as comfort once in the outer space. The cabins where the human use to stay in space are pressurized. There are also light as well as comfortable space suits that are designed to make free movement on a space environment; an air-conditioning system also protects humans from the heat of the sun.
