Speaking of this, Wu Hao pointed to the introduction video played on the large screen hanging next to him, and introduced to everyone with a smile.

"The main body of our inflatable expandable space experiment cabin is a new type of polymer composite material specially developed by us. Compared with some traditional polymer composite materials, our material has many advantages.

For example, in general, this kind of material is prone to aging, hardening, and loss of toughness in the long-term alternation of cold and hot temperatures. But our material does not. It can maintain toughness for a long time in such an environment of alternating cold and heat, and its anti-aging performance is very good. "

"And this polymer composite material is also very strong, because of its high strength, it has strong tensile and impact resistance.

Of course, no matter how strong it is, it is difficult to withstand the impact of those space debris at six or seven kilometers per second or even more than ten kilometers per second.

Not to mention this kind of polymer composite material, even the hardest metals in the world, chromium and titanium, cannot bear it.

Therefore, our human spacecraft did not expect to rely on materials to prevent these debris from hitting, but established an accurate debris detection and prediction mechanism.

Monitor the status of debris in space in real time, so as to adjust the orbit of the spacecraft and avoid debris. "

"Secondly, this is to have good self-healing and repair capabilities. That is to say, after being hit by these debris, the spacecraft can repair itself in time, or quickly repair. This will prevent the situation from deteriorating and threatening the safety of the spacecraft , and even the safety of the astronauts inside the spacecraft.

This time, we put a special liquid into the interlayer of the capsule's polymer composite shell on this inflatable expandable experimental space capsule.

When a leak occurs in the inflatable expandable space capsule, this special liquid will block the leak in the shortest possible time, preventing the internal pressure of the spacecraft and the outflow of air in the cabin.

In addition, the inflatable and inflatable shell constituting the inflatable inflatable test chamber is also made of overlapping materials.

This will further improve the strength of the inflatable expandable space capsule, and its comprehensive performance has even surpassed the metal material shell of traditional spacecraft, which is even better. "

Speaking of this, Wu Hao said with a smile: "We have been closely monitoring this inflatable expandable space test module since it was launched. It has been nearly three months since it was launched, and its orbit has been in good condition. .”

Here, folks, here's what's going on inside this inflatable, expandable space capsule. What we host internally is the space farm experiment project.

After the inflatable expandable space capsule was launched, the space experiment capsule was inflated and expanded, and the space farm experiment project began immediately.

This time, more than 20 kinds of plant seeds accompanied the spacecraft to space. In addition to some vegetables, there are also some wheat and rice, corn, and other food crops such as potatoes and sweet potatoes.

In addition to plants, this time there are also several protein-rich insects and some microorganisms to build a complete space ecosystem at a time.

According to the plan, this inflatable expandable space capsule will fly in space autonomously for seven to eight months to fully verify its own reliability and safety.

In addition, it will also verify whether it is feasible to build space farms and space ecosystems in space capsules.

As you know, the food problem has always been one of the most important problems that plague us humans going into space. At present, the astronauts on all spacecraft in space rely on supplies from the earth to survive.

Every once in a while, the cargo spacecraft carrying these many supplies will take off, dock with the space station, and deliver important supplies to the space station.

For example, the most important water and food for astronauts occupy more than half or even more of the capacity and space of the entire cargo spacecraft.

In the future, humans will land on other planets, such as the moon, Mars, and even further planets

It is a bit unrealistic to rely on earth materials for resupply.

Unreliable and expensive.

Therefore, adapting measures to local conditions and self-reliance are the key issues that scientists are currently studying, and it is also one of the key problems that restrict our human exploration of space.

Speaking of this, Wu Hao smiled slightly: "A few years ago there was a not very famous space science fiction movie called "The Martian". I believe everyone has seen or heard of this movie more or less. The main story of the film is that the hero survived by planting potatoes on Mars.

This isn't entirely bogus sci-fi fantasies, many of which are based on our current scientific research.

For example, we display it based on the relevant data sent back by a series of previous detectors.

In the south pole part of the moon, as well as the landmarks of Mars, there will be a large amount of water resources.

For example, at the south pole of the moon, there are a large number of glaciers and frozen soil, which contain considerable water resources, enough for humans to use on it.

On the surface of Mars, according to NASA's latest detection and research results, there is liquid water on the surface of Mars that changes with the seasons. In addition, in the south pole of Mars, there are also abundant glaciers and frozen soil, and the water resource reserves are also very considerable.

With water resources, this lays the foundation for human survival. In addition to drinking water for astronauts, it can also be used as fuel.

The decomposed hydrogen can be used as rocket fuel, and the separated oxygen can not only satisfy human breathing, but also act as a combustion aid.

The carbon dioxide in the atmosphere of Mars, as well as the carbon dioxide in the exhaust gas of our human breath, is combined with the hydrogen from the decomposition of water to produce another high-quality rocket propellant, methane.

All of these can provide very favorable natural conditions for the survival of our human beings on distant planets.

Of course, the reality may be more difficult than this, and there are still many problems that have not been solved by scientists.

For example, these planets are very desolate, and there is no organic matter in the soil, let alone any nutrients. If you want to grow vegetables and food on these alien planets, you must constantly improve the soil.

This is a huge project that cannot be completed in a short period of time.

So for our human space exploration missions, the best way is this advanced factory soilless cultivation technology.

It does not rely on soil, directly uses hydroponics or air cultivation to carry out factory-scale planting, so as to provide sufficient food supply for astronauts.

And our space farm project also wants to explore this field, so as to achieve the ambitious goal of human beings living in space and on alien planets for a long time. "
