November 18th.

The whole world is watching a big news.

Another landmark event occurred in the field of aerospace, which can be said to be recorded in history.

Brother Long is about to ascend to heaven.

Literal ascension.

He will be an astronaut, together with another partner, on the Falcon manned rocket, into space, and then into the 'Dragon 4' spacecraft, which has been assembled and built, and then go to Mars after a little adaptation.

Whether or not he makes it to Mars or not, he has achieved many feats that no one else has done.

That is, among all astronauts, he is the most valuable, more than 100 billion meters.

Among all the billionaires with a net worth of more than 100 billion dollars, he was the first to enter space and the first to participate in the farthest travel program with a range of more than 100 million kilometers.

If the landing on Mars is successful.

Then he was the first rich man to stand on Mars.

If that fails.

He was the first rich man to die on Mars.

Because he has already spoken: "Whether I am dead or alive, my body will appear on Mars!" ”

Anyway, both horizontal and vertical can set records, and horizontal and vertical will not suffer.

Of course, it is to exclude Wei Ming's hanging ratio.

……

Black Hole Cosmos Development Corporation.

Large aerospace command and control room.

On the giant screen on the wall, thousands of miles away from the United States, the Kerbal Satellite Launch Base, standing under a recyclable Falcon rocket on the launch stand, Elon Musk, wearing a spacesuit, is facing the live broadcast of the audience's speech.

The live stream was watched by 3.5 billion people worldwide.

There are only 45 minutes left until the countdown to launch.

"I love you Dela, I love you Heroise...... I love you forever! ”

in the picture.

Elon Musk, who is about to enter the rocket, is hugging and saying goodbye to his family, and tears are spilling down the scene.

Sensational music also sounded at the right time.

It can be said that a certain tragic atmosphere is brought to the extreme.

The audience applauded.

Countless viewers in front of the screen are either clasping their hands together and praying in their hearts, or their eyes are moist, wiping the corners of their eyes, silently chanting blessings.

At this moment,

With the exception of a very small number of people, they all hoped that he would return safely.

The vast majority of scientific and technological workers and pacifists also hope that he can succeed in igniting the space fever of all mankind, stop internal contradictions and wars, shift attention to the universe, concentrate resources and wisdom, solve the problem of human living space through the method of opening up the universe, and obtain all kinds of resources needed by mankind from beyond the blue star, so that every human being, every nation and country has enough living space.

Make the cake bigger!

Instead of going to destruction in mutual hatred.

Therefore, no matter how you look at it, any space exploration and attempt is a positive thing and deserves support and encouragement.

"Long Gong, what do you think is the success rate of his Mars landing plan?"

Wei Ming watched the live broadcast with interest with interest, and turned his head to ask Long Tianhao beside him.

"No more than 30 percent, and it would be a miracle if it worked." Long Tianhao pondered for a while and said.

"70% chance of landing into a box?"

Wei Ming said in surprise: "This is too exaggerated, if you are not more than ninety percent sure, who dares to gamble like this, why are you so optimistic about him?" ”

"Mr. Wei, to be honest, I also hope that his success rate can be above 90%, but my years of experience in systematic engineering tell me that the success rate is at most 30%."

Long Tianhao shook his head and said: "Musk is indeed a madman with dreams, for this mission, he lost fifty pounds in half a year, developed a sturdy figure, studied sixteen aerospace courses, and all of them were qualified...... Personally, I admire him very much. ”

"But I dare to conclude, not to mention whether he can set foot on Mars, the probability that he will come back this time will not exceed 30%, and it is a miracle to succeed."

"Why do you say that?"

Wei Ming was still puzzled: "In order to ensure success, you can see that the combined body of the 'Dragon 4' spacecraft weighs more than 300 tons, which is 50 tons more than the 'Dragon 3' spacecraft, and heavier than our country's Tianhe space station. ”

"Three hundred tons, hehe~"

Long Tianhao smiled: "Mr. Wei, are you being frightened by those fuel canisters that are tied together and numbering dozens of them?" But do you know what kind of material these fuel tank shells are made of? Double-layer vacuum stainless steel, the kind that can be bought in the ordinary civilian market, looks like a bunch of bluffing, but it is loaded with the cheapest compressed natural gas and liquid oxygen, which is only one-third of the high-performance fuel, and throws one after another on the road, creating a large amount of space junk. ”

"In addition, the equipment and parts in the spacecraft, in addition to the control system and communication system are more advanced, the others can be saved, try to purchase products for the civilian market, redundancy design is seriously insufficient, such as the Mars landing module, he used to do experiments with aluminum alloy sealed tanks, I thought that in the official landing mission on Mars, he would use better carbon fiber materials, but I didn't expect it to be aluminum alloy, it can be seen that he put cost control in the first place, and human life in the second place."

"Isn't that a good idea?"

Wei Ming said: "If you can save it, you can save it, and use the most expensive one for everything, how many people can afford it?" If this model is feasible, after maturity, cheap space will definitely be developed, and ordinary people will be able to enter space. ”

"I'm not against this model."

Long Tianhao said: "But the space environment is far from being as simple as people imagine, it is full of high-energy particles, cosmic radiation, the high temperature side can have two or three hundred degrees, and the low side has more than 100 degrees below zero, how can ordinary materials withstand this test?" ”

"If the redundancy design is insufficient, the circuit protection is insufficient, an electronic component is damaged by high-energy particles, there is no backup, it means that there is a piece of function that is completely unusable, although this is only a low-probability event, the reliability of each subsystem can be 99%, but there are dozens of systems on a spaceship, there are tens of thousands of important parts, if there is a 1% failure rate, then its risk will be high and scary."

"That's why I'm not bullish on him."

In addition, Long Tianhao hates Elon Musk's behavior of throwing space junk all the way, which is completely irresponsible and creates huge security risks to other people's space launch activities.

There is no shortage of wasted resources, even if they are cheap.

"Makes sense."

Wei Ming nodded, if stainless steel fuel tanks, aluminum alloy landing capsules, cheap materials and civilian parts could support a Mars landing mission with a 90% success rate, then a colony base would have been established on Mars a long time ago.

Humanity has entered at least the rudimentary era of interstellar colonization.

“5、4、3、2、1…… Launch! ”

Then.

The Falcon rocket in the picture carried Elon Musk and another partner into the sky, fortunately, this rocket is an unused first-hand rocket, with high reliability, and after more than 800 seconds of flight, Brother Long successfully entered space.

The first stage was successful.
