Seven days later, as the data collection near the lunar orbit was almost done, Zhao Feng and the others also drove their aerospace plane. After two or three days of flying, they successfully returned to the Tiangong Technology Great Desert Space Center.

At the same time, on the second day after their return, Zhao Feng and the others were engaged in intense and orderly preparations.

Because according to the plan, 15 days later, they will set off for the moon again, and this time the purpose is no longer just to fly around the moon in lunar orbit.

At the same time, it is not like the official one before, using detectors to carry out lunar exploration. After all, the official lunar exploration has already been carried out, and there is already enough data, so I am using Phoenix directly for this moon landing. -kt2 type, the aerospace plane directly lands on the moon.

Moreover, they have to carry a lot of various equipment to the moon this time. After all, the aerospace plane can carry a very large weight.

According to the data of the aerospace plane, after the space station is fully refueled, the aerospace plane can carry more than 40 tons of materials to and from the moon.

So this time, in addition to a lunar rover for astronauts, they will also carry multiple unmanned detection robots, or unmanned lunar exploration vehicles, as well as various scientific research and detection equipment. The weight of all these equipment and the lunar exploration vehicle is added up, but it is only a mere 30 tons.

However, considering the limited size of the aerospace plane, and the fact that this moon landing will be their first moon landing by Tiangong Technology, and it will be a vertical take-off and landing landing, for the sake of safety, the aerospace plane does not need to Landing on the moon with a full load. After all, if you land on the moon with a full load, the pressure on the aerospace plane itself is also great. After all, not to mention other things, the weight of the aerospace plane itself and its fuel is as high as more than 100 tons. Such a huge behemoth, want to The difficulty of vertical landing on the moon can be imagined.

Just when Zhao Feng and the others were training hard and preparing to go to the moon for the second time, their second Phoenix-KT2 aerospace plane of Tiangong Science and Technology finally arrived at Tiangong Science and Technology Space Center with all scientific research and technical personnel. With hard work, it was successfully rolled off the assembly line and a series of test flights were carried out.

During this period, the second Phoenix II series aerospace plane also visited many times. Their Ziwei space station of Tiangong Technology carries out supplies and personnel transportation.

Of course, for the construction of the space station, during the training period of Zhaofeng and others, their Tiangong technology did not fall behind, but continued to carry out the construction project at a normal speed.

In just 7 days, when Zhao Feng and the others were preparing to go to the moon for the second time, the volume of the Ziwei space station had grown a whole circle, reaching a mass of nearly 400 tons.

Just like the last time they went to the moon,

This time when they reached the orbit of the space station, the Xinghe space station docked, and moved some astronauts and a small amount of supplies in the plane to the space, and then went to the moon immediately after the space station was filled with fuel.

But because of this time. 7 days have passed. The distance between the earth and the moon has also shortened a lot.

It is about 390,000 kilometers. Therefore, correspondingly, they went to the moon several times at a much faster speed. In less than two days, they have reached the lunar orbit and successfully entered orbit.

"Relying on the command center, the Phoenix 2001 aerospace plane has arrived near the moon and was successfully captured by the moon's gravity. Now it has entered orbit. The aerospace plane is 10,000 kilometers above the surface of the moon. Now we are ready to land on the moon. Request, the command center agrees." As the aerospace plane successfully entered orbit, Zhao Feng immediately sent his request to the command center.

At the same time, he transmitted the real-time status of the aerospace plane to the command center as soon as it was captured by the lunar orbit.

At this time, Wang Bin and others in the command center did not immediately agree to Zhao Feng's request after receiving Zhao Feng's request. Instead, the research and development and technical personnel of the Xianhe base checked the various data of the aerospace aircraft in detail, especially the vertical plane. Take off and land engine data.

After not finding any problems, Wang Bin thought about it, and said to the neutrino communicator: "Zhao Feng, the command center has received your login request, but since your current location is too high in the orbit, High, and the speed of the aerospace plane is still a bit fast. If you log in directly now, the risk factor is high. Therefore, according to the opinions of the experts in our command center, I hope you can reduce the orbital height of the aerospace plane to 50 kilometers from the surface. Then land in a place where the safety factor is higher.”

At the same time, Mr. Qin and the others standing beside Wang Bin also nodded. He was very happy that Wang Bin and the others were able to take the lead in thinking about the personal safety of the astronauts. They did not, because they neglected safety issues in order to land on the moon early. .

"Understood!" Hearing the command center's order, although Zhao Feng was confident that he could land safely at this altitude, he also understood how dangerous it would be to directly land on the moon at this altitude? If it wasn't him, but other astronauts of their Tiangong Technology, the landing success rate would definitely not exceed 50%.

Afterwards, he drove the aerospace plane around the moon and lowered its orbit. When he knew that the distance from the surface was less than 50 kilometers, he submitted a login request to the command center again, and also reported to the Over there at the command center.

The command center naturally agreed to Zhao Feng's request immediately.

As the command center agreed to their login request, Zhao Feng immediately adjusted the flight angle of the aerospace plane again, started to brake the plane, and adjusted the flight trajectory of the plane.

The landing site chosen by Zhao Feng and the others this time is a flat place in a crater. Of course, this is just that there are many moons. The most common one among the craters is not well-known and naturally has no name.

After all, there are large and small craters on the moon all over the moon. If each of them needs to be named, it is impossible to get a name. What's more, the landing site chosen by Zhao Feng and the others is on the back of the moon. Naturally, the most common crater is not May have a name.

Although the aerospace plane has been braking, the speed is still very fast. In less than 10 minutes, the self-driving aerospace plane they were driving was only more than a thousand meters away from the surface of the moon. The speed has already dropped, only about 80 meters per second.

At this time, the engine of the aerospace plane continued to work until the aerospace plane was less than 100 meters away from the surface of the moon. At this time, the engine at the tail of the aircraft had stopped working, and only the vertical take-off and landing engine of the aerospace plane was still working. Work, and the descending speed of the aerospace plane has also dropped to less than 10 meters per second, and it is still falling.

Just when the aerospace plane was only one meter away from the ground, the speed of the aerospace plane's descent had dropped to 0.1 meters per second. That is to say, at this time, the aerospace plane seemed to be hovering one meter above the surface of the moon. .

Although it looks like a hanging screen, in fact, the aerospace plane is still descending slowly. It's just that the speed is very slow, only one meter away, but it took Zhang Feng and the others nearly a minute for the aerospace plane to stabilize. landed on the surface of the moon.
