If it is usual, no matter how effective the cancer suppressant drug is, Lao Mi will not agree to exchange all the research data of Pfizer's three major pharmaceutical giants, and at most give a part of it, even if it is very good.

However, the market price of a technically similar commodity is not fixed, but changes with the change of market background.

When it comes to cancer discoloration, human beings all over the world have a heartfelt fear of cancer.

If there are no cancer suppressant drugs, then it's fine, everyone depends on their fate, I die, you die, but if cancer suppressant drugs appear, Huaguo is enjoying radical cancer treatment, but they can't enjoy it......

People are dying and crazy, no one can guide emotions or anything, the cancer patient group and the families of the patients in Lao Mi will spontaneously attack the government to protest, which will cause great turmoil in the whole society of the country.

After all, their tradition is to pull banners on the street when they are unhappy, and they usually pull banners for environmental protection and animal protection, not to mention that this involves life.

So pinched this handle, on the twelfth day of the year, the Gregorian calendar time came to February 5th, Lu Yi and Li Yashan spent a few days blackmailing most of the mainstream countries, and the remaining third world countries were handed over to Li Yashan to follow up, and then they flew to the aerospace industry base.

"Commander-in-chief, the large detection instruments provided by Lao Mi have been sent over, our planet exploration instruments have also been put in place, and the spacecraft launch plan is scheduled for the 14th."

As soon as he got off the plane, Professor Su, who came to pick him up, told Lu Yi the latest situation of the Mars exploration plan, and the document on Lu Yi's appointment as the commander-in-chief of the Mars exploration plan had been issued two days ago, and the situation that someone was dissatisfied with Lu Yi as the commander-in-chief in the bloody plot did not appear.

One is that Lu Yi's prestige and knowledge are qualified, and the other is that the main reason why this project can be carried out, that is, the spacecraft that transports large exploration instruments to Mars are all private, what do you dare to say?

"So quickly, the leader told me that the construction was only completed in mid-February, and why was the launch planned on the 14th."

Lu Yi, who has been with Li Yashan for the past few days, has not been paying attention to this matter all the time, and when he heard that the planned launch of the 16th was a little surprised, I didn't even see my own spacecraft, so you plan to send it to the sky?

"Commander-in-chief, that's when the construction is complete and the three inspection tests are completed."

Professor Su smiled bitterly and explained: "Now that the spacecraft has been built as a whole, it is being commissioned and checked to confirm whether there are any omissions in the design and construction of the spacecraft, and if there are no problems, a test flight will be conducted."

After collecting data for a test flight, the second commissioning improvement is carried out and then the second test flight is carried out, and about three test flights are carried out, and the altitude and difficulty of each test flight will be increased until it is completely determined that there is no problem.

If there is no problem, then the process of testing and commissioning can be completed on the 12th, and it will take two days to arrange the detection instruments and equipment, and then it can be officially launched. ”

"Let's go, let's see what happened to my ship by the engineers at the Space Base."

Hearing that his spaceship had been built and was undergoing the final inspection, Lu Yi suddenly became interested, beckoned Professor Su to hurry back to the base, and said quickly as he walked: "In addition, let the other scientists in the project team prepare, and I will confirm the details of the entire spacecraft landing plan later." ”

"Yes."

Professor Su looked at Lu Yi's resolute appearance, and couldn't help but think of some friends who had participated in the controlled nuclear fusion project in the past, saying that Commander Lu did not treat himself as a human being, ate and lived in the laboratory or on the plane every day, and at the same time did not treat other scientists as human beings, and suddenly had a bad premonition in his heart.

When Lu Yi and Professor Su had just returned to the spacecraft manufacturing and inspection area of the aerospace industry base, three scientists and engineers who had followed the large exploration equipment and instruments of the United States were standing in the distance watching the engineers of the space base comprehensively inspect the spacecraft, and at the same time let out exclamatory comments from time to time.

“Oh God！ Lu, I'm so happy to see you in reality, is this delicate little treasure yours? It's simply amazing! ”

When Lu Yi and Professor Su appeared, one of the scientists in the United States suddenly showed a happy smile, stepped forward and opened his hand to give Lu Yi a hug.

"No, I don't like hugging men, maybe Professor Hill you transplant your already bald hair, and then go to Korea and Thailand to give it a makeover, I might accept it."

Lu Yi hurriedly dodged away, looked at Professor Hill and said in English with some surprise: "Why did Mi Guo let you come over this time, there is no one in NASA?" ”

"We came with the detection equipment, otherwise you are not familiar with the equipment and will not be able to use it accurately."

Professor Hill explained, then picked up a spacecraft parameter table in his hand, pointed to the data on it and said to Lu Yi in amazement: "Lu, is this spacecraft yours, the total mass of the spacecraft is 236.31 tons with full propulsion fluid, but the engine thrust is as high as 236,000 kN, which is enough to send more than 13,000 tons of instruments and equipment to Mars, is your Huaguo's space engine already so advanced?" ”

"If you look at the general description of the engine at the back, you will understand that this thrust is very reasonable."

Lu Yi said a word and looked at the spacecraft being inspected, the shape was very similar to the Kunpeng fat girl, but the belly was bigger, there were hidden engine vents in other directions on the side, and there were two spacecraft launch ports in the lower abdomen.

Because the thermal expansion engine uses continuous work output, the original engine involves the use of superconducting graphene wires, and the magnetic field blocking limit can withstand a thrust of up to 28,000 kN.

After replacing the metallic hydrogen, the magnetic field strength was increased without expanding the engine compartment and nozzle space, and the thrust of the tolerable limit was 24.5 kN, and the actual output limit was set at 23.6 kN for safety.

"Only adding 50 tons of propulsion fluid can support us to fly to Mars for a round trip?" Lu Yi looked at it for a while, then turned his head and asked an engineer from the space base next to him.

The initial spacecraft design was only 136 tons, of which 20 tons were propulsion, and when it was learned that it was going to Mars, the spacecraft designers changed the spacecraft design and added a large fuel tank to add 50 tons of propulsion fluid.

"Commander Lu, you underestimate the energy output of the nuclear fusion reactor and your thermal expansion engine that uses metallic hydrogen as a superconducting coil, after landing on Mars and unloading the exploration instruments, the spacecraft will have no problem going back from a trip to Uranus."

The engineer of the space base said confidently: "The 70-ton fully loaded propulsion fluid is designed to be fully loaded with 13,000 tons of equipment and instruments to complete the longest distance of Mars in four days. ”

"The apogee of Mars is 400 million kilometers, and one round trip in 4 days, the sailing speed must reach 2,500 kilometers per second, and the spacecraft's protection ability is so strong? And how much overload can the ship's structure and materials withstand? ”

Lu Yi was a little surprised when he heard this data, the energy shield technology is still a million miles away from humans, and the current spaceships rely on armor to resist the impact of space meteorites.

If the speed is really increased to 2,500 kilometers per second, according to the kinetic energy formula Ek=mv^2/2, a small meteorite of 1 gram hits the spacecraft head-on at a relative speed of 2,500 kilometers per second, and the energy of the explosion is 3.1 billion joules, which is equivalent to the explosion of nearly 750 kilograms of TNT explosives.

And there are quite a lot of small meteorites of about 1 gram in the space in the galaxy, and it is a high probability event to travel 100,000 kilometers and collide two or three times, and there is a large amount of space dust in the galaxy, although their mass is very small, but when the speed increases to a certain extent, it is also a big obstacle to the spacecraft.

On the one hand, the issue of protection is also a very important indicator of how much overload the spacecraft's materials and structural design can withstand.

This also determines whether the spacecraft can accelerate faster, and whether it can complete the quick dodge operation when it finds a large meteorite in front of it when traveling at high speed.

Overload is not good, the spaceship accelerates slowly, and high-speed sailing will not be able to quickly dodge the obstacles in front of it and crash into it, or forcibly dodge but directly tear the spaceship apart due to excessive overload.

When he was a child, seven-year-old Lu Yi was very obsessed with mobile suits, and he liked the Gundam battles on the cartoon very much, and he went to his grandmother's house with Lu's mother during the summer vacation to grab the remote control to watch, and he was curious to ask his cousin, who came back from college during the summer vacation, if he could become a Gundam fighter when he grew up.

It just so happened that at that time, his cousin was unhappy because he was robbed of the remote control in the Legend of Sword and Fairy, and he was also a wonder.

took out a pen and paper, drew a schematic diagram while cooperating with gestures with emotion, and vividly explained to Xiao Lu Yi what inertial overload is and what is rotational centrifugal force with the phenomenon that people will tilt when turning in a car, and then told Xiao Lu Yi that it is impossible for humans to become Gundam fighters, and everything on TV is a lie.

Because the overload generated by the sharp turns and sudden changes of direction of the Gundam at high speed will exceed the limit of the human body, will make people unconscious, and even crush and explode people into a pile of flesh and bones......

That cousin's narration directly ruined Lu Yi's childhood, and indirectly prompted him to choose physics as a neurological major in college.

So now when I hear that the spacecraft has traveled back and forth to Mars in 4 days, and the sailing speed has reached 2,500 kilometers per second, in addition to the protection against meteorite collisions, the spacecraft will also be noticed to be overloaded.

Even if you don't need to carry people, the design of materials and structures must follow the basic laws of mechanics, and there will be overload limits.

"The front of the spacecraft will use a layer of modular reactive armor that can be intelligently replaced, and behind the reactive armor is a high-strength titanium alloy and carbon fiber material to form a matching armor, so as long as the armor protection does not hit a meteorite weighing tens of kilograms, it will be safe and sound.

If you really want to encounter a meteorite of more than 10 kilograms, the spacecraft is equipped with a high-precision long-range radar, and the intelligent system can identify and dodge in advance. ”

The engineer at the space base explained: "As for the overload of the spacecraft, because we use the latest carbon composite materials, the toughness and strength of the material have been greatly improved, and with the latest spacecraft structural design, the maximum overload can reach 72 G." ”

"72 Gs? 705.6 meters of acceleration? Are our materials so good? ”

Lu Yi frowned, the spaceship is not a solid piece of iron, because of the welding and connection of various internal parts, and the precision of the internal equipment is also very high, and the overload bearing capacity is really not as good as ordinary air-to-air missiles.

The general air-to-air missile overload is between 40 and 50G, but its own spacecraft can reach 72G? What kind of material is used to make it so awesome.

"Tell me how much my spaceship costs?"

Lu Yi had a bad premonition in his heart, he really didn't pay much attention to the specific manufacturing of the spaceship, or he hadn't paid too much attention to the matter of spending money, and only said the best.

"Uh...... The latest carbon composite materials used in the spacecraft have just entered the stage of industrial mass production, so the cost of materials is quite high. ”

Hearing Lu Yi ask about the cost, the engineer of the space base said with some embarrassment: "Because this is the task arranged above, and the landing is to command your spacecraft, our manufacturing costs and labor costs are exempted, so if you calculate the price of equipment and materials alone, it will cost about 38 billion yuan." ”

"Without counting nuclear reactors and engines?"

"This ...... Not counted. ”

The engineer of the space base saw that Lu Yi's face suddenly darkened when he saw that he had just finished speaking, and hurriedly explained: "But I assure you that this spacecraft is definitely worth the money, and the design and technology used on it are absolutely the best in the world."

Even if you don't use it yourself for a long time, the large spacecraft of various countries has not yet been completed at this stage, and you can use it for commercial business to fly more than ten times into space, and you can turn it back. ”

"You guys really don't feel sorry for spending my money."

Lu Yi rubbed his forehead with a headache, the previous space rockets, spacecraft, space stations and other expenses were very strict, it is conceivable that these engineers have definitely been holding back for a long time, this time when they encounter their own wronged bosses, the various technical ideas in their hearts can't help but roll, while swaying their knowledge and enthusiasm, the cost of the spacecraft is also rising slowly......

Nearly 10 billion US dollars, 60 billion yuan to build a spaceship with a mass of more than 200 tons, how extravagant this should be.

"When will the spacecraft be able to test fly?"

Lu Yi didn't care about the cost of the spaceship, this matter was really distressing, it was also his capital boss Li Yashan was distressed, and she estimated that after knowing about it, she was going to scold him for how to lose.

Of course, in other words, it is really not enough, after all, there is no shortage of money for tomorrow group with cancer suppressant drugs on the market.

is really short of money, Lu Yi can also apply to the above, I believe that tens of billions of funds will come in an uproar, although it is refreshing to use public funds for research without personal funding.

"It will take about 20 minutes to check and commission, and then you can conduct a test flight." The engineer who spoke to Lu Yi inquired about the progress and gave an answer.

"Then as soon as possible, I'll see how this 60 billion guy flies."

Lu Yi nodded, the relevant test runway has already been built, and even the huge thrust of the metal hydrogen thermal expansion engine is no problem to directly launch and take off without the runway.
