Chapter 709: Facing mistakes requires more than courage

When everyone saw this main design drawing, they were stunned by the content above. No matter from which angle they were viewed, they were impeccable. Even a little closer, you can see unexpected results. Picture.
"Ugh?"
"That's not right!" Lao Feng, who was in charge of the rocket department, discovered that the standard of this drawing was not the Chinese standard, but...but the American standard. This...reasonably, Xu Mang could not commit this. The mistake made the standard wrong.
unless...
The main design above is the main design of NASA's Curiosity.
"This..."
"This is not the design drawing of NASA Curiosity?!" Lao Feng said in horror: "The above standards are completely different from ours. I don't believe that Professor Xu Mang, you think this is the case, unless this is NASA's Curiosity. Design of the rover."
As soon as the voice fell,
The meeting room was like boiling water, boiling instantly.
Everyone, including Zhang Ju, looked at Xu Mang together, hoping that he could give a reasonable explanation as to how NASA's rover design appeared in his hands.
"Cough!"
"This is a beautiful accident." Xu Mang said with a smile: "I forgot what I used in exchange for...oh! By the way... the Xu Yang structural formula I found uses an extension of this formula The equation is changed to NASA’s Curiosity rover design."
"???"
"???"
"???"
This this...
Is this a loss or a gain?
Everyone present knows Xu Yang’s structural formula. This is a Nobel-level discovery that was misread. But Xu Mang is more a thief and keeps holding his hands and does not publish it. However, it is because of this situation that many important things have been changed. technology.
but...
In private, he actually switched to NASA's Curiosity rover design drawings. This... it is simply unimaginable. The United States should have been deceived by Xu Mang once. They did not believe in evil and proposed a formula for replacing Xu Yang's structure.
"Process..."
"I won't go into details here." Xu Mang said awkwardly and politely: "Anyway, I was so angry at the time that there was a story about switching to aerospace engines."
Everyone smiled bitterly, this is really the case.
"Then what..."
"I have a showdown. The Bajie rover is copied from Curiosity, but don't worry...it has its own property rights!" Xu Mang said with a smile, "They dare not speak in America, they can only admit that we are ourselves. R&D, anyway, just say it’s me."
Immediately after,
Xu Mang began to introduce the main functions of the Mars Rover Bajie.
"In terms of hardware, I deliberately used the chip processor developed by my old husband's company, which can provide powerful computing capabilities. Of course, I will use a system specially developed by me in the future, which is a real-time operating system used in a large number of embedded systems."
"The use of the design life is two Martian years, but it should actually exceed it. In terms of ancillary equipment, the design is completely in accordance with the indicators given to me by the space agency. Except for the deceleration parachute and the heat shield, I replaced the power source with A multi-task radioisotope thermoelectric generator is provided."
"About 30 years of service life... This part is the mast camera. The Mars handheld lens imager is moved to this position. The original lens imager position has been changed to the Mars landing imager. At the end of the robotic arm, there are alpha particles. Roentgen ray spectrometer."
"This location..."
Xu Mang spoke for half an hour without letting go of every detail. Everyone present could not help being shocked by this Bajie Mars rover, and at the same time conquered by Xu Mang's unparalleled transformation ability.
Finished,
Xu Mang was about to drink, but Academician Jin found him with doubts.
"Professor Xu Mang?"
"I took a look... The weight control is very good, but after careful calculation, it seems that the weight is missing by five kilograms." Academician Jin said: "It is in the middle of the rover. Such a space is actually empty. No...this location is for the self-help program?"
Xu Mang took a sip of water, nodded and said, "Yes! It's the self-rescue program."
Next second,
Xu Mang clicked on another file.
"Under normal circumstances, nine accidents in ten accidents happen quickly, but once a car overturns on Mars, it is basically cool." Xu Mang said with a smile, "Although the center of gravity has been reduced to the lowest under my design, as long as it doesn't appear Martian storms can hardly cause overturns."
"But... if there is a car overturning situation, then there is a high probability that there will be a meteorite impact, geological activity, extraterrestrial creatures and even Transformers." Xu Mang said seriously: "But take a step back, if it does happen. Overturned, in fact, there is nothing I can do."
"???"
"???"
"???"
This...
How can I help myself?
When the fire was confused, Xu Mang turned the page, and a central processing system appeared in front of everyone.
"This is a data processor that I developed. It can systematically analyze the surrounding things. It is the last safety guarantee of the Bajiehao." Xu Mang said: "Automatically calculate the height and drop, cut the bevel, and plan a safe route."
"Sorry..."
"NASA didn't give me a design concept for the self-rescue program. It was all my own." Xu Mang said helplessly: "Once the rover overturned, it was basically impossible to save. It was all expensive instruments. If you don’t, it’s useless."
"and so!"
"Safety lies in preventing trouble before it happens." Xu Mang said: "Once the Bajiehao's self-rescue program senses danger, it will intervene and finally get out of danger."
Words fall,
Xu Mang glanced at several people present and found that they were all silent, while their eyes were fixed on the projection.
"well!"
"This system is very important!" Zhang Ju relied on his keen intuition and said seriously: "Xu Mang...can you use this patent for us in the future?"
"Take it away!"
Xu Mang smiled and said, "I have nowhere to use it anyway."
Words fall,
Xu Mang regretted it, and hurriedly said, "Wait...it can be used, but the patent is mine!"
Zhang Ju smiled: "Did you find any business opportunities? Can it be used in cars?"
"Sorry..."
"I want to support my family, my wife... is a shrew, if she knows that such an important technique is given to others, I am afraid I will be beaten when I go home." Xu Mang directly threw the pot to Xiaoman, anyway she Not here.
"..."
"..."
"..."
I dare to say too!
But it's a shame to get married so young.
"the following."
"It's about... the sky crane design plan." Xu Mang opened the third file, then raised his head and said: "The sky crane design, I didn't get the relevant drawings, it was I based on the NASA photos to design myself. From here."
however,
These words touched everyone's heartstrings. If what Xu Mang said is true, then this technology is not that mature. Immaturity represents danger, but it is different from self-help programs, which are just computer programs. That's it, but the sky crane is mechanical equipment.
If something goes wrong, it will be too late to operate, so during the period from entering the atmosphere to landing, it will be in the black for ten minutes and it will be operated by the sky crane.
If in case,
A certain detail was not done properly, and the result was a crash, the tens of billions of investment was gone, and several years of hard work was wasted.
"We need to drop from 20,000 kilometers per hour to 0.5 meters in ten minutes..." Xu Mang said indifferently: "So the sky crane must be combined with the Bajie, in a safe range. Inside, use a cable to hoist the Eight Rings from the sky crane and hang it below."
"When the distance to the ground is a certain height, the cable will be automatically cut off, and the sky crane will then land within a certain safe distance from the Bajie." Xu Mang said, "It's probably like this. In fact, the sky crane is not complicated."
"This... the process is very troublesome." Xu Mang did not want to hide the truth, and said helplessly: "A series of actions need to be successfully completed, including using a parachute to slow down and igniting a rocket to prepare for landing, so that the mass of the rover can reach 3 tons. The speed of the lander was reduced from a bullet to a smooth landing."
"It must accurately execute hundreds of programs and 700,000 lines of program code. As long as there is an error in one of them, the Ba Jie rover is very likely to hit the surface of Mars and be broken."
Words fall,
The expressions of everyone present became very bad.
Hundreds of programs, 700,000 lines of program code, who can be sure that there will be no fatal errors?
"I disagree!"
"This is too risky!" Academician Qian said solemnly, "Professor Xu Mang...I don't doubt your ability. You have been amazing, but people will make all kinds of mistakes, in case you show up. What should I do if I make a mistake?"
For this view,
Xu Mang did not have the power to refute, pondered for a long time, and said: "I admit that this process is very dangerous. A little carelessness will lead to accidents, which will lead to the collapse of the entire plan. Everyone will fall into the pressure of public opinion, but the problems we have encountered , NASA also encountered it."
"Why can they?" Xu Mang asked, "But we can't? Or else... Regarding the landing method of the rover, you can show it to the public, and then put me in front of the public, even if there is a problem. I can carry it alone."
"..."
"..."
"..."
Zhang Ju looked at Xu Mang and said solemnly: "You will not be allowed to face all of this alone. As a whole, you will have to bear the consequences together. But what you just said made me very touched by the path of aerospace development. Originally, it was full of unknowns. Who doesn't know what will happen next."
"to be frank..."
"We flinched a little~EbookFREE.me~ Zhang Ju took a look at everyone present and smiled bitterly: "Isn't it normal to fail?" You could face failure before, why can’t it now? "
"About the landing method."
"Officially adopt the sky crane method, Professor Xu Mang...The problem of the program code behind, it is up to you to solve it." Zhang Ju said seriously: "Go bold and rest assured. If anything goes wrong, everyone will carry it together!"
"but..."
"I have a request." Zhang Ju smiled and said, "Bajie is too ugly. Change a name!".
Xu Mang pondered for a while, and said cautiously: "White Cat?"
