Indeed, the price difference between satellites is really large, and ordinary small satellites may be able to be developed and manufactured in hundreds of thousands or millions. Some large satellites often cost hundreds of millions of dollars in R&D and manufacturing.

However, large satellites like this are generally used for military purposes. For example, Lao Mi's military communication satellites, military reconnaissance satellites and some military satellites with special roles have a maximum R&D and manufacturing cost of more than one billion US dollars.

As for the prices of some commercial satellites from high to low, the hundreds of millions of dollars quoted by Lao Ma are actually relatively normal.

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

The second is in the area of business communications, which is also the focus of both companies. Compared with the old horse, the little horse brother is more eager. This move has a great role in promoting their overseas business expansion and is also a new direction for their business development.

And for the old horses, they also have the intention of doing this. Moreover, Lao Ma is more inclined to commercial satellite communication business and has a strong interest in it.

In the face of the eagerness of the two, Wu Hao naturally introduced the details to them very enthusiastically and patiently. This is a very high-quality potential customer, how can 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 outside made everyone's faces red from the wind.

So everyone immediately said goodbye and returned to the base, rested a little in the lounge, drank a sip of hot tea to warm up, and then visited 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, but because of the large number of visitors, the laboratory did not open experimental subjects in life science and animal research, but led everyone to a huge glass greenhouse.

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

"Dr. Yang, I'm sorry to interrupt your work." Wu Hao looked at Yang Fang, who was wearing a white lab coat with a hot figure and a good face, and said with a smile.

"Hehe, it's okay." Yang Fang shook her head at Wu Hao, and then smiled at Erma and said, "Teacher Ma, Mr. Ma, welcome to our Haoyu Institute of Science and Technology Biology and Life Sciences, Northwest Research Center to visit.

The greenhouse, which you see at the moment, is the species cultivation center of our drought-tolerant plant cultivation program, and of course, some plants from other programs will also be cultivated here.

Here, I would like to introduce to you the basic situation of our entire drought-tolerant plant cultivation project. ”

Seeing that Erma nodded, Yang Fang smiled at everyone and introduced: "Our drought-tolerant plant cultivation project was established at the suggestion of Mr. Wu, and I myself was appreciated by Mr. Wu to be responsible for the research and development of this project.

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

Different from ordinary drought-tolerant plants, we hope to be able to breed new plant varieties suitable for growing in arid areas, which can play a role in preventing wind and sand fixation and improving the ecological environment.

For example, we know that the growth rate of moso bamboo is very fast, basically in more than ten hours, the bamboo shoots of moso bamboo can be drilled out of the ground, and in a short period of time, it rises several meters or even more than ten seconds to form a new moso bamboo.

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

Moreover, the root system of moso bamboo is also very developed, not only the root system can be connected, but also can go deep into the ground for more than ten meters or even dozens of meters.

However, this kind of bamboo is not frost-tolerant and is not suitable for growing in the north, and if the temperature is too low, the bamboo may freeze to death.

Secondly, this kind of bamboo is not suitable for growing in arid areas, it likes water, and generally grows in areas with more humidity and abundant precipitation.

Therefore, 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.

In addition, there is a reverse engineering. That is, the fast-growing genes in moso bamboo are extracted, and then transferred and fused into some drought-tolerant plants and crops to accelerate the growth of these plants and crops.

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

If we succeed in developing this technology, we will be able to transfer this fast-growing gene into some of the best woody trees. This makes it possible to breed some high-quality tree varieties that grow faster, resulting in a stable and environmentally friendly wood yield.

Or, we can transfer this fast-growing gene into some tall crops and pastures, so that we can provide high-quality and low-cost forage and forage 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 more such examples, and we hope to be able to apply this technology to more fields for the benefit of humanity as a whole. ”

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

As for the quick-witted little brother, he immediately threw out a very sharp and direct question: "At present, the safety of such genetically modified plants and crops has not been verified, how to ensure that these plants and crops will not affect the local ecology after they appear, and even cause serious consequences, and ultimately threaten us humans." ”

The question raised by Xiao Ma Ge is also a question that is often asked in genetically modified technology, and it is also a major reason why genetically modified technology cannot be promoted on a large scale.

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

In addition to this direct food, such as vegetable oil, soy sauce, vinegar, and wine, as well as the soy products you eat, such as tofu, yuba, and spicy strips you hold, there may be genetically modified crops.

Raw materials such as soybeans, corn, sesame, peanuts, and rice may all be genetically modified crops.
