In 2135, supported by the postwar dividend and led by the heaven-sent fierce woman, Dr. Fang, China began a grand leap forward in technology with great fanfare.
Space technology flourished, the aerospace industry grew increasingly badass, humanity's exploration and understanding of cosmic space kept improving, its ability to survive beyond Earth steadily increased, and the colonization of Mars was placed on the agenda.
However, Dr. Fang also put forth many conclusions: modern humans were not suited to surviving in space.
In the environment of space travel, even setting aside the obvious issues of extreme heat and cold, humanity still had many urgent problems to solve.
First, the body's resistance to cosmic radiation was far too weak. Human skin provided poor protection against cosmic rays, which could directly damage human chromosomes. As a result, every spacecraft and spacesuit had to pile on vast quantities of radiation-shielding materials, reducing the effective payload capacity of space vessels.
Second, space travel involved spending most of the time in a weightless state. In weightlessness, not only did daily life become a problem, but human health itself was continuously weakened.
In a weightless state, all matter naturally converged toward its center, taking on a spherical shape.
Humans were no exception.
All the blood in the human body naturally gathered toward the middle, placing enormous pressure on the heart while also bringing many unforeseen problems.
For instance, humans found it extremely difficult to reproduce in a weightless environment.
This was somewhat counterintuitive.
The effects of weightlessness penetrated every aspect of the internal organs, bodily functions, and blood flow. This whole set of human organs worked well on Earth, but in space, it was basically useless.
Third, and most importantly, there was time.
Objects in the universe moved far too quickly. In the blink of an eye, a
