"What, what's the problem?"

Seeing Zhang Xiaobo's hesitation, Li Wei frowned and said.

"Well, no, basically not."

Zhang Xiaobo actually wanted to say that there were still a few problems, but he didn't understand them, but the strict prohibition of the engineering man told him that there was indeed no big problem, and the function was basically consistent with the description.

But...... He really wanted to think about it and study the black technology in it again.

"Since there is no problem, let's sign it quickly, don't delay my time, and don't affect the diplomatic relations between Xia and Gang."

Livi glared at him, and gave a vague warning, Xia has always attached great importance to diplomatic relations, coupled with the joint suppression of Western forces in recent years, Xia has made friends and won over friendly countries one after another.

Now that Levi's big hat of 'don't destroy the relationship between the two countries' has been pressed, Zhang Xiaobo, a small engineering man, obviously can't bear it, so he immediately picked up a pen and signed the document.

The review and testing of the satellite was thus passed.

"Levi, if you don't put that satellite here, we'll keep it for you, this thing is high-precision equipment, and it will be broken if you are not careful, so don't bring it back."

Zhang Xiaobo didn't expect that after he finished signing, that Levi took the satellite in his hand and put it back in his backpack, ready to take it back.

This disrupted his plan, and he was a little speechless, Levi didn't believe that he was still something, and he didn't even put the satellite here for safekeeping...... There is one of the safest and most advanced nitrogen storage boxes in the laboratory, and if you put the satellite in it, you will be able to take it out after 10 years.

It's safe and secure.

Levi didn't trust them, and the high-precision satellite was carried with him, if he bumped into it......

He had to popularize the storage and maintenance of satellites, and suggested that Levi put the satellites in the laboratory for safekeeping.

"No need,"

Livi looked at him lightly: "It is the national treasure of Gangbia, I must carry it with me, and with its quality, it will not be broken for a hundred years." ”

Then he put on his backpack and left the laboratory.

Looking at Levi's back and looking at the backpack, although the strong curiosity was like 10,000 ants gnawing on the heart, Zhang Xiaobo was still helpless.

……

Three days later, on July 3rd.

Li Wei and Lin Guoming returned to the aerospace science and technology company again.

Small meeting room.

They participated in a meeting of experts dedicated to the two of them.

Discuss the option of a launch vehicle to send a small satellite into space.

Looking at the dozen or so experts present to introduce the situation, Levi felt that they valued him and was very satisfied.

Green channel.

This is the so-called green channel.

At the meeting, Zhang Baohua, deputy chief designer of the aerospace science and technology company, opened a few PPT pictures and introduced to Livi:

"Mr. Li, for the country's first satellite, our aerospace science and technology company has prepared two sets of suitable launch plans."

"A launch plan: carrying our most reliable technology of the expedition No. 3 type rocket, the rocket weighs 244 tons, can launch the satellite into an orbit of more than 200 kilometers, and one of our newly developed 'Fengyun No. 4' meteorological satellites into space, in addition to carrying six domestic company network communication satellites, plus your country's communication satellites...... The total is eight stars with one stone. ”

"B launch plan: equipped with our company's most mature technology Expedition 2C rocket, the rocket weighs 242 tons, can launch the satellite into an orbit of more than 500 kilometers, accompanied by a remote sensing satellite, a marine satellite jointly developed by Xia and other countries...... The total is three stars with one stone. ”

Levi looked at the introductory picture on the PPT.

He thought for a while and asked, "Chief Master Zhang, what is the launch success rate of your company's Expedition 3A and Expedition 2C?" How reliable are they? ”

"Both types of rockets are the 'gold medal rockets' of the aerospace science and technology company, and they are among the best in the world in terms of reliability."

"Of course, there are slight differences."

Zhang Baohua paused and continued: "Yuanzheng No. 3A has carried out a total of 28 launch missions, all of which have been successful, and the launch success rate is 100%, so it is the most reliable. ”

"Expedition 2C has carried out a total of 71 launch missions, 69 successes, 2 failures, and a comprehensive success rate of 97.18%, but its two failures are distributed in the first 30 launches, and the next 41 consecutive launches have been successful, so it is the most mature technology."

"These two types of rockets are very reliable choices, and they are both worth recommending."

Listen to these explanations.

Levi's index finger tapped on the table and began to ponder.

According to Chief Master Zhang, the Expedition No. 3A has a very high launch success rate and has not missed a single miss, but it is a relatively new rocket, and the total number of launches is relatively small.

As for the Expedition 2C, there were two failed launch accidents in the early stage, but all the last 41 were successful, and a total of 71 rounds were fired, the technology is extremely mature, and the probability of the subsequent launch failure is extremely small.

"These two rockets, no matter which one, can indeed be chosen, and they are enough to be reassuring."

Levi said secretly in his heart, and suddenly another question came to mind.

He looked at Zhang Baohua and asked, "Chief Master Zhang, can you tell me when these two rockets will be launched?" ”

"You're asking about the launch window, right?"

Zhang Baohua nodded and said: "The launch window of Expedition 2C is in early to mid-July; The launch window of Expedition 3A, from late July to early August, is the closest to the two, and the interval will not exceed a month. ”

Early July?

Hearing these words, Livi's eyes lit up, and he immediately said: "That's not better than choosing again, just Expedition No. 2C!" We will send our satellites into the sky as quickly as possible. ”

"Mr. Li, please think about it safely!"

At this time, Zhang Xiaobo, who also participated in this meeting, suddenly spoke: "After all, Expedition No. 2 C has two failed experiences, and it is not absolutely reliable, if you want to ensure higher reliability, I suggest you choose Expedition No. 3A, which is a gold medal rocket with a 100% success rate." ”

Zhang Xiaobo didn't understand why he wanted to intervene like this, maybe he had been thinking about it in his heart for the past few days, and his mind was all occupied by the little blue satellite, and he faintly seemed to want it to go to the sky.

He really wants to study that little satellite again!

"Now 100%, does that mean there will be no problems in the future?"

Levi glared at him with displeasure: "You are still a scientist, the success rate is a matter of probability, and daring to open your mouth to guarantee 100% success is not in line with science, so I value the maturity and reliability of the technology more than the simple success rate." ”

"In my opinion, the reliability of Expedition 2, which has experience of failure and excludes potential hidden dangers, is higher than that of Expedition 3!"

"So, I'm going to go Expedition Two!"

This is naturally Levi's high-sounding words, he actually chose the annunciator earlier.

"Good! Then, according to what Mr. Li said, we will immediately start the relevant arrangements on the Expedition 2C. ”

Zhang Baohua nodded.

The type of launch vehicle on board was determined on this.
