What does 11,863 tons of carrying capacity mean in spaceflight?

The largest launch vehicle in human history, Saturn V, has a lunar capacity of 45 tons, and the Tomorrow trip is 263 times that value, and it is still going to Mars.

The large communication satellites of mankind are about 2 tons, and the large detection satellites that Lao Mina claims to be able to shoot people's faces in space are less than 2 tons, which means that ignoring the space factor, Tomorrow can transport 5,000 large satellites at one time.

"Commander Lu, 6 Mars global communication satellites have been arranged, 12 optical exploration satellites, 78 remote sensing exploration satellites have also been arranged, and the spacecraft is descending to the surface of Mars for the deployment of exploration instruments, collection robots and rovers."

On the third day after the launch of Big Fat Girl, the Mars communication system composed of satellites and the space exploration system composed of optical detection and remote sensing detection satellites were arranged.

"Activate communications, optical detection and remote sensing satellites first." Lu Yi looked at the crimson planet on the screen and ordered.

In 4 billion years, apart from the occasional meteorite fall, Mars has welcomed the largest extraterrestrial visit.

Next, Tomorrow will deploy 138 large fire seismometers and 138 large heat flow probes in various areas of Mars, and will cooperate with space optical detection satellites and remote sensing detection satellites to conduct a three-dimensional and all-round accurate analysis of Mars.

In addition to the fire seismometer and heat flow probe, 60 amphibious rovers integrating surface exploration, ground drilling and diving detection will be launched, and each probe will be equipped with three multi-purpose collection robots and corresponding analysis instruments to track and detect suspicious areas on Mars.

At this time, there are still a few months before the Martian window, and the distance between the Earth and Mars is still more than 150 million kilometers.

Through the satellite communication station of the Mars exploration group, the command is transmitted to the communication satellite in the earth's space, and then the electromagnetic wave spends more than 8 minutes to transmit the command to the satellite system of Mars.

All the satellites were activated and began to take high-precision photographs and remote sensing of Mars according to the instructions, and more than an hour later, a more accurate Martian data was returned through the link of the communication satellite.

The supercomputer is rapidly analyzing these data, and the images of Mars on the screen are constantly refreshed, rows of parameters are refreshed on the screen, and red, green and yellow areas are marked, which are all abnormal and suspicious areas where the material composition is different from the environmental soil.

The red signal area is the most, which is suspected to be the metal accumulation area, and the green area is less, from the remote sensing signal feedback, it is the underground lake or ice deep in the earth's crust, and the yellow one is less than 100, which is suspected to be a coal mining area.

"This ......"

When the latest remote sensing data of Mars was refreshed, everyone in the Mars exploration team was stunned with wide eyes.

It's so regular, these signal areas are too regular!

Fortunately, the green suspected groundwater is good, there are not many large and small signal points, and most of the range is concentrated in the polar region, which is not surprising to everyone, because the water ice at the poles of Mars has long been confirmed.

What really stunned everyone was the yellow signal area of suspected coal, the signal was very clear, and 93 of the 97 signal areas were concentrated in the equatorial region, like a skirt around the Martian equator.

What shocked everyone even more was that the signal response of the metal with relatively high purity detected by remote sensing was almost mixed with these coal areas, and the red metal signal response in other areas of Mars was not of high purity, which was not much different from the general ore veins in nature.

"It's definitely a trace left by the Martians!"

"With such a strong carbon signal response, this must be carbon-based life, and from the point of view of the location in the equatorial region, it is a life with a high demand for light!"

The people in the exploration team became emotional, and the Mars InSight probe found anomalies from seismic wave parameters to determine that Mars once had civilization, but that was only a seismic wave parameter, and the specific details were not known.

However, the data fed back by the large satellite remote sensing system is a macroscopic exposure of the traces left by the Martians, and from the perspective of intensive carbon reactions, there is no doubt that it is carbon-based life, and it is densely distributed in the equatorial region, indicating that this is a life race with a relatively high demand for light.

The most important thing is to determine that the Martians are carbon-based life types, which can determine that the Martian magnetic field was a very stable existence during the existence of the Martians, and it only disappeared later after an unknown accident.

If there is no magnetic field on the planet, carbon-based life may be able to survive under the solar wind, but it is absolutely impossible to develop advanced life and intelligent civilization.

"There is a question about this, since it is carbon-based life, then referring to the ecological environment of the earth, not only the equator, but also other regions will definitely have life reproducing."

While everyone was excited, some people calmly asked: "I think that under the premise of the existence of a magnetic field, the atmosphere is not thin and there is water vapor transpiration, the ambient temperature of Mars will be lower than that of the Earth, but it will not be much lower, and it will definitely not be only the equator where life can reproduce."

The long reproduction of carbon-based life deposits large amounts of carbon, which is also the origin of coal and oil.

From this point of view, the coal area detected by Mars remote sensing should not only be around the equatorial region, but also in other temperate regions and even cold regions. ”

"Could this be the use of coal and oil by the Martians, collecting the world's coal and oil into the equatorial city area, and eventually the extinction of civilization will be left in the equatorial region."

"The use of coal and oil is nothing more than burning, and the carbon in coal and oil will also become carbon dioxide and carbon monoxide will be re-emitted into the atmosphere after combustion, and even if you don't burn a single place, the exposed air will slowly weathered and undergo a slow chemical reaction to convert into carbon dioxide or carbon monoxide emissions to the atmosphere.

The carbon emitted into the atmosphere is absorbed and redeposited by vegetation, which is the carbon cycle of the entire planet.

The existence of the carbon cycle determines that carbon may be enriched in a certain area of the planet, but it will not be like now, except for the equatorial region, there are almost no coal enrichment areas in the rest of the region......"

"Commander Lu, this ......" Everyone couldn't debate, and they all looked at Lu Yi.

"It's too early to draw conclusions."

Lu Yi shook his head and ordered: "Change the original release plan, except for the placement of the fire seismometer and heat flow probe according to the original plan, 60 rovers will be put into Mount Olympus and directly opposite Mount Olympus, two will be put into the north and south poles of Mars, and the remaining 50 will all be put into the top ten shallow areas of 93 coal-rich areas on the equator!" ”

The Martian magnetic field is conservatively estimated to have disappeared for 4 billion years, which means that the civilization above it has been dead for at least 4 billion years.

Ordinary paper will rot after a few months of being buried in the soil, and it will turn gray after decades of exposure to the air.

As for electronic storage items, if they are buried in permafrost, it is fine, they can be stored for a thousand years, but if they are in an ordinary environment, because of the influence of thermal movement on the storage medium, the information stored inside will be completely lost without a hundred years.

The higher the precision of electronic products, the higher the temperature and humidity of the environment, and the shorter the storage time of stored information.

With the existence of thermal motion, unless the temperature is lowered to absolute zero, the particles at the microscopic level of any object will be mixed together for a long time.

Therefore, Lu Yi has no hope at all about finding the information storage items of the Martian civilization and the civilization information left by the Martians, and this stored information may have been completely lost within thousands of years after the disappearance of the Martians.

He only hopes to find out the cause of the extinction of the Martian civilization from the fossils, from the decay of the elements, from the geological evolution of the planet.

The unexplained and strange demise of a civilization that is in the same solar system and no less powerful than human beings feels too terrifying and terrifying......
