Spacecraft are often inhabited by one or more astronauts that launch into outer space through a powerful rocket launched from Earth, thanks to which he is able to reach the moon. It is required by it, and the spacecraft is launched consisting of three main sections, the vehicle itself that roams in space, a special external tank for liquid fuel, and finally two solid fuel rockets for propulsion.

There is great interest in space vehicles and atmospheric pressure through aeronautical medicine. This branch focuses on the effects of acceleration factors on humans. Because the high altitude causes serious problems to human life.

Pressure inside the spacecraft

When spacecraft begins to rise to more than 10,000 feet, the amounts of oxygen and atmospheric pressure begin to gradually decrease; Therefore, the symptoms of lack of oxygen and atmospheric pressure begin to appear on humans, as a person becomes more likely to lose his life after reaching an altitude of more than 50,000 feet, even if he breathes 100% of oxygen, so it requires him to wear his space suit that provides him with the ability to withstand the great drop that Atmospheric pressure, temperatures, and oxygen occur in altitudes. When the astronaut reaches a height of 40 thousand, the atmospheric oxygen pressure may drop automatically and at a high speed, which poses a threat to life. As for the critical height, it is considered if it reaches 87 mm / Hg.

Atmospheric pressure in spacecraft is closely related to the lack of oxygen; As the oxygen concentration in the astronaut’s blood inside the spacecraft rises automatically when he exceeds an altitude of more than 10,000 feet, that is, more than 16,000 feet above sea level, the blood pressure rises and the speed of blood circulation increases. nervous.

Interior condition of the spacecraft

From the inside, the spacecraft lives in a state of microgravity as soon as it enters a space orbit, as the contents of the spacecraft begin to fall automatically as a result of the weightlessness inside the vehicle, so this condition is known as zero gravity as well, and the fall is towards the ground and not randomly, and it is indicated that to avoid this situation Gas is pumped into the fuel depots at high pressure to prevent the hot air from rising, but activates the air circulation through the fans, so dust and water particles begin to spread in the cabin and collect in the fan filters.
