Military Technology

Indeed, the price difference of satellites is really huge, and ordinary small satellites can be developed and manufactured in hundreds of thousands or millions. And some large satellites often require hundreds of millions of dollars in research and development and manufacturing costs.

However, such large satellites are generally used for military purposes. For example, Lao Mi's military communication satellites, military reconnaissance satellites, and some military satellites with special functions, the R\u0026D and manufacturing costs can reach up to more than one billion US dollars.

As for some commercial satellite prices ranging from high to low, the quotation of hundreds of millions of dollars mentioned by Lao Ma is actually quite normal.

It can be seen that both Penguin and Ali have their own development plans in the aerospace field. It's no wonder that both companies have their own commercial map business, which is learned from G song. The reason why the map business of the two companies obviously lags behind G song is that they do not have their own optical remote sensing satellites.

The second is in the field of business communications, which is also the focus of the two companies. Compared with the old horse, Xiao Ma is more eager. This move has greatly promoted their overseas business expansion, and it is also a new direction for their business development.

As for Lao Ma, they also have the intention in this regard. Moreover, Lao Ma is more inclined to commercial satellite communication business, and has a strong interest in it.

Facing the eagerness of the two, Wu Hao naturally introduced the details to them enthusiastically and patiently. This is a very high-quality potential customer, how could Wu Hao let it go so easily.

I didn't stay at the launch site for long. On the one hand, I didn't want to disturb the on-site technicians who were making final preparations too much. On the other hand, the pure northwest wind outdoors made everyone's faces flushed by the wind.

So everyone left immediately and returned to the base, took a short rest in the lounge, drank a sip of hot tea to warm up their bodies, and then continued to visit under the guidance of Wu Hao.

This time Wu Hao took them to visit the biology and life science laboratory that Lao Ma wanted to see very much. However, due to the large number of visitors, the laboratory did not open the experimental subjects of life science and animal research, but attracted everyone To a huge glass greenhouse.

As soon as you walk into the greenhouse, it seems like you have come to spring. The climate is humid and warm, and the birds are singing and the flowers are fragrant. The scientific researchers have raised several parrots in the greenhouse here, which are everyone's group pets and are very pleasing.

"Dr. Yang, I'm interrupting your work." Wu Hao said with a smile as he looked at Yang Fang, who was wearing a white lab coat with a hot figure and a pretty face.

"Hehe, it's okay." Yang Fang shook her head at Wu Hao, then said with a smile at Er Ma: "Mr. Ma, Mr. Ma, you are welcome to visit our Haoyu Technology Institute of Biology and Life Sciences and Northwest Research Center.

The greenhouse you see so far is the species cultivation center of our drought-tolerant plant cultivation project. Of course, some plants of other projects will also be cultivated here.

Here, I will mainly introduce to you the basic situation of our entire drought-tolerant plant breeding project. "

Seeing that Erma nodded, Yang Fang introduced to everyone with a smile: "Our drought-tolerant plant cultivation project was established under the suggestion of Mr. Wu, and I myself was appreciated by Mr. Wu to be in charge of the research and development of this project. .

As the name suggests, the main topic or goal of our project is to use biological gene editing and transgenic methods to study and cultivate drought-tolerant plants.

Different from ordinary drought-tolerant plants, we hope to breed new plant varieties suitable for growing in arid areas, which can play the role of windbreak and sand fixation and improve the ecological environment.

To give an example of our ongoing project, everyone knows that the growth rate of moso bamboo is very fast. Basically, within a dozen hours, the bamboo shoots of moso bamboo can be drilled out of the ground, and in a short period of time, the bamboo shoots can grow several meters or even In ten seconds, a new moso bamboo is formed.

In addition, the growth rate of Moso bamboo is also very fast. In just a few years, a dense bamboo forest can be formed, which is ideal for wind and sand protection.

Moreover, the root system of moso bamboo is also very developed. Not only can the root system be connected into one piece, but it can also go deep into the ground for tens of meters or even tens of meters.

However, this kind of bamboo is not frost-resistant and is not suitable for growing in the north. Once the temperature is too low, the moso bamboo may be frozen to death.

Secondly, this kind of bamboo is not suitable for growing in arid areas. It likes water and generally grows in relatively humid areas with abundant precipitation.

So our goal is to use biological gene editing and transgenic technology to transfer and integrate the drought-tolerant genes in some drought-tolerant plants into moso bamboo, so that moso bamboo can adapt to the growth and survival of arid areas.

Also, there is a reverse engineering. That is to extract the fast-growing genes in moso bamboo, and then transfer them into some drought-tolerant plants and crops to accelerate the growth of these plants and crops.

Maybe everyone can't understand what I said, so let's give another example or imagine.

If we successfully develop this technology, we can transfer this fast-growing gene into some woody trees. This allows for the development of high-quality tree species that grow faster, resulting in a consistent and environmentally friendly wood output.

Or, we can transfer this fast-growing gene into some high-stalk crops and pastures, so that we can provide high-quality and low-cost pastures and silage for animal husbandry. It can not only reduce the cost of animal husbandry, but also solve the contradiction between animal husbandry and environmental protection to a large extent.

Of course, there are many such examples, and we also hope to apply this technology to more fields, so as to benefit the entire human being. "

Hearing Yang Fang's introduction, Lao Ma and Xiao Ma also showed very interested expressions on their faces.

As for the quick-witted little Ma, he immediately asked a very sharp and direct question: "At present, the safety of this type of genetically modified plants and crops has not been verified, how to ensure that these plants and crops will not It will have an impact on the local ecology, even cause serious consequences, and ultimately threaten us humans."

The question raised by Brother Xiao Ma is also a question that is often asked about genetically modified technology, and it is also a major reason why genetically modified technology cannot be widely promoted at present.

In fact, whether we like it or not, genetically modified technology has penetrated into our daily life. For example, some of the food we eat may be genetically modified crops.

In addition to this kind of direct food, like the vegetable oil, soy sauce, vinegar, and wine that everyone holds every day, as well as the soy products you eat, such as tofu, yuba, and spicy strips you hold, there may be genetically modified crops in them .

The raw materials in these foods, such as soybeans, corn, sesame, peanuts, and rice, may all be genetically modified crops.
