Chapter 489

Seven days later, as the data collection near the lunar orbit was almost the same, Zhao Feng and his team also flew their space plane. After two or three days of flight, they successfully returned to the Tiangong science and technology desert Aerospace Center.

At the same time, on the second day after their return, Zhao Feng and them put into intense and orderly preparations.

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

At the same time, unlike the previous officials, they use detectors to land on the moon. After all, the official lunar exploration has been carried out and has enough data. Therefore, I directly use phoenix-kt2 to land on the moon.

And they have to carry a lot of equipment to the moon. After all, the weight that an aerospace plane can carry is very large.

According to the data of the space plane, after the space station is filled with oil, the space plane can carry more than 40 tons of materials to and from the moon.

Therefore, in addition to shoelaces and a lunar rover for astronauts, they will also carry a number of unmanned exploration robots, or unmanned lunar exploration vehicles, as well as various scientific research and exploration equipment, and all the weight of these equipment and lunar exploration vehicles will add up to only 30 tons.

However, considering the limited volume of the space plane and the fact that this lunar landing will be their first lunar landing by Tiangong technology, and it will also be a vertical take-off and landing landing landing, for the sake of safety, the space plane does not need to land on the moon with full load. After all, the space plane itself will be under great pressure if it lands on the moon with full load. After all, nothing else, The weight of the space plane itself and fuel alone is as high as more than 100 tons. It is conceivable that it is difficult for such a huge monster to make a vertical landing on the moon.

When Zhao Feng and his team worked hard to train and prepare for their second trip to the moon, at this time, their second Phoenix kt2 space plane of Tiangong technology was successfully offline and carried out a series of test flights with the efforts of all scientific and technical personnel at Tiangong technology space center.

During this period, the second Phoenix II Series aerospace aircraft also went there many times. They use the Ziwei space station of Tiangong technology to supply materials and transport personnel.

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

In just seven days, when Zhao Feng and his team were preparing for their second trip to the moon, the space station Ziwei was a whole circle larger and had reached a mass of nearly 400 tons.

Like the last time they went to the moon, this time when they reached the orbit of the space station, Xinghe space station docked, and moved some astronauts and a small amount of materials to the space. Then, after the space station was filled with fuel, they went to the moon immediately.

But at this time. Seven days have passed. The distance between the earth and the moon has also been shortened.

It is about 390000 kilometers, so they went to the moon several times, and the speed is much faster. In less than two days, they have reached the lunar orbit and successfully entered the orbit.

"Relying on the command center, the Phoenix 2001 space plane has arrived near the moon and successfully captured by the lunar gravity. Now it has entered orbit. The space plane is 10000 kilometers away from the lunar surface. Now we are ready to land on the moon, and the command center agrees." with the successful entry of the space plane into orbit, Zhao Feng immediately sent his request to the command center.

At the same time, when the space plane was captured by the lunar orbit, he transmitted the real-time status of the space plane to the command center.

At this time, Wang Bin and others in the command center did not agree at the first time after receiving Zhao Feng's request. Instead, the R & D and technicians of Xianhe base checked various data of aerospace aircraft in detail, especially the data of vertical takeoff and landing engine.

After finding no problems, Wang Bin thought about it and said to the neutrino communicator: "Zhao Feng, the command center has received your login request. However, because your current position, that is, the orbital altitude is too high, and the speed of the aerospace aircraft is still a little fast, if you log in directly now, the risk factor is high. Therefore, according to the opinions of experts in our command center, I hope you can reduce the orbital altitude of the aerospace aircraft to 5 from the surface Land at a place of 0 km, so the safety factor is relatively high. "

At the same time, Qin and others standing beside Wang Bin also nodded. He was very happy that Wang Bin and others could take the lead in thinking about the personal safety of astronauts. No, because they neglected safety problems in order to land on the moon early.

"Understand!" hearing the command from the command center, Zhao Feng was confident that he would land safely at this altitude, but he also understood how dangerous it would be to land directly on the moon at this altitude? If it were not him, but other astronauts of their Tiangong technology, the landing success rate would never exceed 50%.

Then, he drove the space plane around the moon to lower the orbit. When he knew that it was less than 50 kilometers from the earth's surface, he put forward a login request to the command center again, and reported the location of his landing site to 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 aircraft again, began to brake the aircraft and adjust the flight track of the aircraft.

The landing site chosen by Zhao Feng and them this time is a flat place in a crater. Of course, this is only the most common crater with many moons. It is not famous and naturally has no name.

After all, large and small craters on the moon are all over the whole moon. If each one needs to be named, it can't be taken at all. Moreover, the landing site chosen by Zhao Feng is located on the back of the moon. Naturally, a most ordinary crater can't have a name.

Although the space plane has been braking all the time, the speed is still very fast. In less than 10 minutes, the self driving space plane they are driving is only more than 1000 meters from the lunar surface, but at this time, the speed of the space plane has been reduced, probably only 80 meters per second.

In this space-time, the engine of the space-time aircraft continues to work until the space-time aircraft is less than 100 meters from the lunar surface. At this time, the engine at the tail of the aircraft has stopped working, and only the vertical takeoff and landing engine of the space-time aircraft is continuing to work, and the descent speed of the space-time aircraft has been reduced to less than 10 meters per second, and continues to decline.

Just when the space plane is only one meter away from the ground, the descent speed of the space plane has dropped to 0.1 meters per second, that is to say, the space plane is hovering one meter on the surface of the moon.

Although it looks like a hanging screen, in fact, the space plane is still descending slowly, but this speed is very slow, only one meter away, but it took Zhang Feng and them nearly a minute to land steadily on the surface of the moon.
