Chapter 865: Can we farm in space?

Chang Haonan would naturally take an active part in such an ambitious project as the ocean surveillance system.

However, he did not agree immediately.

After all, Ocean No. 1 is definitely still a civilian satellite belonging to the State Oceanic Administration to the outside world.

Therefore, the data obtained by other devices on the satellite also need to be processed.

However, this will put a lot of computational pressure on the system.

You know, it took him an entire night and a morning to process that picture using a supercomputer.

Although the single imaging area of ​​the ocean monitoring satellite will not be as terrifying as millions of square kilometers like Resources-01-, it will still be a huge burden for the onboard computer with poor performance.

After organizing his words, Chang Haonan raised his concerns to Luan Wenjie:

"Director Luan, you also saw it last time at the Tanzhou Measurement and Control Station. The calculations for data extraction and dimensionality reduction are quite complicated, and there are quite a few black box parts involved."

"As far as I know, the computers on satellites may have worse performance than ordinary commercial computers due to energy consumption and radiation protection issues?"

Luan Wenjie also decisively agreed with Chang Haonan's statement:

"Indeed, the performance of onboard computers cannot be improved in a short period of time. At least, it cannot be compared with supercomputers on the ground."

However, he then changed the subject:

"So our Ocean No. 1A satellite is still mainly for technical verification. As long as we can process part of it on the satellite side and ensure that the timeliness is improved compared with the resource series satellites, we will not deliberately pursue specific indicators and data."

With these words, Chang Haonan felt relieved.

After all, he didn't cross boundaries much in his previous life, and his understanding of the aerospace field was basically limited to the public part and a few pieces of information obtained during exchanges with peers. He couldn't figure out the specific development level of a certain technology like he did in his old profession.

However, the general trend is definitely to improve satellite computing power and reduce the pressure on ground stations as much as possible.

Otherwise, no matter how fast the data processing speed of the ground station is, it will have to go through one or more data transmission processes with the terminals that really need the remote sensing information, such as ocean-going strike formations or scientific expedition units.

It is difficult to achieve real-time or quasi-real-time reconnaissance.

"That's no problem."

Chang Haonan nodded:

"But I will probably spend most of my time in Shengjing for the next two or three months. The earliest I can participate in your project will be in December this year."

"Is the Taihang project about to be finalized?"

Ding Gaoheng, who was behind the desk, suddenly interrupted and asked.

After the establishment of the General Armament Department and the group restructuring of the five major military industrial corporations, the administrative approval authority for the design and finalization process was gradually transferred from the Science, Technology and Industry Commission to the former.

Anyone with a discerning eye can see that with the development of the national economy, especially the significant boost to the machinery industry brought about by the establishment of the Equipment Industry Department, the country is considering gradually removing the militarized color of the Commission of Science, Technology and Industry for National Defense.

For example, Zhang Hongbiao, the recently transferred deputy director, and Luan Wenjie, who is rumored to be promoted to deputy director soon, both have no military status.

“Yes, the national appraisal is expected to begin at the end of September, and the design will be finalized before the end of the year.”

Chang Haonan replied.

Although the entire R&D process of the WS-10 went smoothly, the national certification process for design finalization is quite detailed and standardized, and no projects will be reduced just because you have been going smoothly before.

Even if you pass all the subjects in one go, it is not an exaggeration to say that it will take about two months.

And this is good luck, as it was almost winter. Otherwise, it would not be uncommon to wait for extremely cold temperature conditions to take half a year or even more than a year for identification.

"It doesn't matter."

After Ding Gaoheng and Chang Haonan finished their conversation, Luan Wenjie waved his hand:

"Ocean monitoring... well, the equipment requirements for ocean science satellites and land remote sensing satellites are different, so we are currently working on the final hardware. The integration with the software program will not start until the end of the year. Please make your own arrangements."

"Besides, your core algorithm should be ready-made, and you should only need to optimize it..."

……

After finishing the topic of Ocean No. 1, Luan Wenjie stood up and prepared to say goodbye to Ding Gaoheng:

"Then Director Ding, my work is done. You and Comrade Haonan..."

"Wait a minute, wait a minute..."

Chang Haonan quickly stopped the other party:

"I have already said what Director Luan wanted to talk to me about, but I haven't said what I wanted to talk to Director Luan about."

As soon as he entered the room, he was drawn into the other party's topic, and it turned out that he had not yet finished the main business he came here for.

How could I let Luan Wenjie run away like this?

Luan Wenjie, who had already picked up the briefcase, sat back down.

"It seems like you two are destined to be together..."

Ding Gaoheng half-jokingly looked at the two people on the sofa and said:

"You both came to me on the same day to ask each other for favors?"

"It's a coincidence indeed."

Luan Wenjie looked at Chang Haonan:

"I don't know why Mr. Chang came to me..."

"Look, I have a project on hand, hoping to use space breeding to obtain some beneficial crop traits. It just so happens that there is a launch mission for Shenzhou II early next year, so... can you arrange a space for it in the mission payload?"

The latter is also straightforward.

We are all working on serious projects, there is nothing to be embarrassed about.

"Space breeding..."

Not only Luan Wenjie, but also Ding Gaoheng showed some surprise on their faces:

"Isn't this research in the field of agronomy... Xiao Chang, are you secretly researching this?"

"It's definitely not me. I don't know much about agriculture... I don't know the difference between the five kinds of grains, but it's not much different anyway."

Chang Haonan made a joke, not too big, and then continued to explain:

"Actually, this matter is also related to the Ziyuan-2 remote sensing satellite that Director Luan just mentioned."

Hearing this, Luan Wenjie and Ding Gaoheng instantly became interested.

"I have processed several photos taken by the Resource-01 satellite of the central and western regions of my country. I found about 80 pieces of abnormal information data that had never been observed before. Then, based on the recent geological exploration results, we found that desert terrain that meets certain characteristic conditions has the potential to be improved into soil..."

"..."

Chang Haonan spent a few minutes briefly introducing his plan to turn sand into soil.

Of course, the specific technical parts have been removed.

After all, he couldn't possibly take out a small blackboard and teach the other two people.

"In short, according to Professor He Guangyou, who has extensive experience in sand control, after completing soil transformation, it is best to plant some plants such as tall fescue and cosmos to stabilize the soil base, and then use soybeans, alfalfa and ryegrass to maintain the soil."

“It just so happens that researcher Zhuang Bingchang, who happens to be involved in our project, is an expert in soybean breeding, and it was he who wanted this opportunity.”

"Zhuang Bingchang..."

Seeing that Ding Gaoheng had no intention of making the first decision, Luan Wenjie raised his head slightly and pretended to recall:

"I seem to have an impression of this name. He seems to have submitted an application during the Shenzhou 1 mission. However, we took into account that soybean seeds are relatively large in size and weight, so under the same conditions, the priority was relatively low, and he probably was not selected..."

Then he looked at Chang Haonan:

"However, since this is the situation that President Chang mentioned, it meets the conditions that may promote key projects. There is definitely no problem in raising the priority."

"Of course, in principle, this matter still needs to be communicated with the chief design team responsible for the specific task, but I will coordinate it. You can ask Researcher Zhuang to submit a supplementary explanatory document to us..."

It was even smoother than Chang Haonan had imagined.

It was not until the two of them finished discussing this matter that Ding Gaoheng, who had been silent until now, suddenly spoke:

"Xiao Chang, the main body of your sand-to-soil technique, I mean the main body before the transformation, doesn't it have to be sand?"

This somewhat difficult question made Chang Haonan think briefly:

"I haven't calculated the others, but theoretically, as long as some basic conditions are met, such as a certain degree of binding force and shear resistance, and the climate conditions and water and fertilizer conditions are not too bad, there will be corresponding improvement methods."

"Well……"

Ding Gaoheng lowered his head to think and did not continue speaking.

"Director Ding, what you mean is..."

After a short period of silence, Chang Haonan asked tentatively.

"Oh, just some half-baked ideas."

Ding Gaoheng then raised his head again:

"I was thinking, after decades or hundreds of years, when we land on an extraterrestrial planet, is it possible to use your technology to farm there?"
