Determine and Overcome the Astrophysics Challenges of Deep Space Journeys

Because biological sensors work in the human blood circulatory system to coordinate the blood pressure with the heart`s pulse pressure via organizing the diameter of blood arteries that exist in each organ to organize the pressure in each organ (with the heart pulse pressure), the functions of these biological sensors distort during a microgravity environment that may create imbalances in the blood pressure in the human blood circulatory system, but during a long space journey, these distortions will last a long time, as long as the duration of the long space journey. Therefore, the health deteriorations of the astronauts after the long space journey are due to permanent distortions of the blood circulatory system that happened during the long space journey; therefore, it could result in permanent physical distortions of the blood circulatory system that make the astronauts suffer from high liquid pressure in some specific organs and even have some effects on eye health and causes health deteriorations generally. Therefore astronaut's room in the spacecraft should be a spinning room to generate the centrifugal force as an artificial gravity force to prevent astronauts from any sort of health deterioration due to the lack or absence of gravity force during the space journey. In the meantime, it should be in a temperature range of 25 °C, depending on the central heating of the spacecraft. Therefore, we should consider several concerns when designing a spacecraft that can generate a centrifugal force as an artificial gravity force, docking spacecraft safely, and learning from our previous mistakes to avoid spacecraft accidents. Where the operation temperature was the main technical reason behind the failures of SpaceX spacecraft. Therefore, all spacecraft should be able to guarantee the required heat for all equipment and engines within the limits of their operating temperature during space journeys, using multi-layer tissue composed of high-density metals and ultra-high-strength alloys for the external body of the spacecraft to prevent any failure due to reducing the temperature as much as the spacecraft’s travel away from the sun`s heating rays.
