"If we don’t adopt large-scale structures to block solar radiation, there will be no obvious traces," another academician said.
Huang Xiuyuan said an idea, "Maybe we can consider transforming irregular asteroids to camouflage the spacecraft in the future."
In fact, many people in the Federation have studied this technical direction, and their research projects are all around the camouflage technology exhibition
Including natural asteroid bunker, imitation asteroid bunker and modulated radiation camouflage technology.
The ultimate goal of these technical directions is to let observers see that the sun is not artificial but a large natural asteroid.
The most advanced and difficult technology is the modulation radiation camouflage technology 2.
The principle of this technology is very simple, that is, absorb the radiation from the outside and emit the modulated radiation.
We should know that the most intuitive observation technology at present is to judge the temperature, quality and planetary class through star radiation.
What gravitational waves and mesoscale classes can’t judge whether a star is intelligent or not.
Unless human beings actively edit gravitational waves and launch them in all directions, it is possible for alien texts to discover the secrets of the sun by deciphering gravitational waves and neutrinos.
However, magnetic wave and light wave communication are actually difficult to be received by alien languages due to energy exhaustion and cosmic background radiation interference.
Unless the distance between two texts is very close, it usually takes no more than 1 light-year between the two parties to have a certain chance to receive the ultra-long wave communication signal sent by the other party.
The Space Investigation Bureau has focused on all the stars with a solar radius of 3 light years, and no signs of alien languages have been found so far.
Therefore, long-wave communication is temporarily available, and gravitational waves and mesoscopic phenomena have been brought into strict control by the Federation.
Even if gravitational waves and mesoscale experiments are to be carried out, they must be carefully examined to avoid exposing the sun coordinates during the experiment.
When Huang Xiuyuan and others discussed it,
A wood-building synchronous track is projected from the surface of the test elevator cabin to give the elevator cabin an initial speed by arranging the surface magnetic catapult.
Because the synchronous orbit to the near-earth orbit is a near-real environment, the elevator cabin will fly to the blue star ground at high speed after being ejected by the magnetic catapult.
The distance of 360 thousand kilometers is only 120 thousand seconds, that is, 2 minutes, for the average speed of 3 kilometers per second.
Actually, the speed of the elevator cabin can be faster, so there is no need to control and brake because the speed is too fast.
Moreover, the cruising speed is 3 kilometers per second, which is synchronous orbit, and the low-earth orbit speed is close to the ground at an altitude of 200 kilometers. This speed must be adjusted.
In the stage of entering the atmosphere, if the speed of cargo transportation elevator cabin is generally not higher than 24 kilometers per hour, it will decelerate at a constant speed; If it is a passenger ship, the speed is generally not higher than 12 kilometers per hour, and it is also decelerated at a uniform speed.
In addition, the elevator cabin can be stopped halfway, but it is usually not chosen to stop halfway.
And if you want to transport materials to low-earth orbit and middle-level orbit, you can use special elevator cabins.
When the elevator cabin reaches the specified track height, the cargo cabin will be ejected while running to ensure the smooth rope of the elevator.
After 3 hours and 2 minutes, the test elevator cabin finally descended from the wood-building synchronous orbit to the ground of Bell Island.
The ground is like a concentric elevator cabin, which is quickly unloaded by workers and sent to the maintenance room for surface inspection.
At the same time, another elevator cabin is launched from another cable on the ground and adopts magnetic ejection mode at the same time.
Chapter seven hundred and seventy Venus
The test of the wooden ladder is going on in an orderly way.
On the other hand, the atmosphere of Venus is located in the floating city of Yingzhou Island in the Antarctic circle of Venus, and it has gradually expanded to an area of 3 square kilometers.
Yingzhou Island is the Venus agricultural testing ground for the construction of Shennong Basin.
After more than a year of testing, Venus Agricultural Testing Site has gradually completed the testing of various agricultural products and various cultured animals, and some agricultural products have been officially approved to obtain mass production qualification.
Another batch of new astronauts came to Venus to change shifts one after another, and the number of astronauts who came to change shifts this time reached more than 24.
The Venus Agricultural Test Site is divided into two parts: Venus Shennong Company and Venus Agricultural Research Institute.
Naturally, China Venus Institute of Agricultural Sciences will continue to test agricultural products and cultured animals.
