Deja Vu

"The sense of déjà vu," originally called "Deja Vu" in French, translates to 'seems like a previous encounter'. In 2124, when humans gaze upon the sky from their lunar base and see a blue planet, that feeling of déjà vu harmonizes with the ancient's appreciation of the moon on Earth, a shared sentiment. It seems that there has always been a subtle connection between the moon and earth. The design of the lunar base combines a new rocket launching method to concretize this connection and continuously promote the development of human civilization.

 The development of civilization is inseparable from the support of resources, and since the industrial age, human exploration of the earth and the development of resources have been accelerating. These huge resources have greatly promoted the development of mankind. At the same time, the development of human beings has also led to the rapid depletion of the earth's resources, according to the surface of relevant studies, the use of some of the earth's main resources such as energy exploration and exploitation is not proper for the rapid consumption of non-renewable energy and the price of energy continues to rise. The impact of resource depletion is not limited to the stagnation of scientific and technological development, in the future of a hundred years, the huge resource crisis will have a huge impact on global politics, economy and culture.

By 2124, humans plan to build the first lunar base. This is an era of crisis, the construction of the base not only needs to promote space research, but also slove the more realistic problem that the base ought to quickly provide lunar resources for the earth to alleviate the earth's serious resource crisis, so as to continue to promote the development of human science and technology.

As early as a hundred years before the construction of the base, humans have experimented with a new type of rocket launcher, which continuously accelerates the rocket to a set speed by making it pass through a circular orbital device and then launched. Compared with the traditional solid fuel rocket launch method, this new launch method greatly saves energy consumption with low cost and high efficiency. However, due to the influence of the gravity and air resistance, it is difficult to accelerate rockets to faster speeds on Earth while on the moon with the low gravity and vacuum environment, this launch method was perfectly realized and can be put into use.

The lunar base is built on a smaller branch of the Rain Sea Rift Valley, and humans take advantage of the low gravity of the moon to erect the foundation on the Rift Valley. At that time, the developing direction of the lunar base will have the potential on both horizontal and vertical. Humans can go to the lunar surface through the base bridge and use the advantages of the rift valley to quickly reach the depths of the moon for mining and research. The construction of the lunar base will be quickly assembled and built by industrial robots and the prefabricated integrated module will be launched to the moon through 3D printing technology. All cabins are built by modular manufacturing to make it convenient to the construction and renewal of the base. People can assemble the corresponding cabin on the base with the help of robotic arms according to the actual functional needs, meanwhile, the damaged or aging cabins can be replaced in time to realize the self-renewal of the base. The outermost part of the base is an advanced ring rocket accelerator, which can efficiently and quickly transport resources collected on the moon back to Earth, and receive cargo rockets from Earth to make close material connection with Earth.

We want humanity's first base to be a milestone for the important role of the base is playing in not only helping humanity alleviate the planet's resource crisis but constantly promoting the connection between extraterrestrial planets and human beings, furthermore helping human beings quickly realize space colonization. As the first lunar base of mankind, through its efficient launch method, it can continuously transport important resources to other lunar bases (without launching from the earth), assisting more and larger bases to be built quickly on the moon. At the same time, bases in different regions of the moon can also transmit the surrounding unique resources (water ice, mineral deposits, rare elements, etc.) to other bases through this launch method, so that it is more comprehensive and stable for the development of human beings on the moon. Until the lunar colonization reaches a mature stage, larger bases could use this launching form to the extreme and the lunar base will serve as a transit station for humans to travel from Earth to other extraterrestrial planets such as Mars (humans only need to use a small amount of fuel on Earth to reach the large lunar base, and then enter farther space exploration at a higher speed through accelerators)

Finally, the lunar base can be used as an important reference for the construction of any bases on other planets.
