The construction period of the "Kunpeng" is longer than that of the "Eagle Falcon", not because of the large size of the "Kunpeng", but because of the more advanced technology used in the "Kunpeng".

The space inside the "Kunpeng" is far larger than that of the "Eagle Falcon", and even if the "Eagle Falcon" is not used to land on Mars, the "Kunpeng" alone can transport all 12 astronauts to the surface of Mars at one time.

Of course, this situation is only a backup situation, which means that this method will only be used if the "Falcon" has problems and cannot be used. According to the normal plan, when landing on Mars, the "Eagle Falcon" and "Kunpeng" will be dispatched at the same time.

The appearance of the "Kunpeng" can be said to be another insurance for the Mars spacecraft. The Kunpeng's fuel tanks are loaded with up to 280 tons of chemical fuel, which is equivalent to the chemical fuel stored in 12 fuel tanks if the Kunpeng is not used.

And if the "Kunpeng" does not pull astronauts to land and completely pulls all kinds of materials to land on Mars, the materials carried by the "Kunpeng" alone will be enough for the astronauts to build a small forward base on the surface of Mars. The life-sustaining system installed in this small forward base can accommodate 12 astronauts for up to six weeks.

The appearance of "Kunpeng" also made Tang Feng have a small adjustment to the manned Mars exploration plan, that is, to build a small forward base on the surface of Mars. If you're going to do it, why not make it bigger?

Of course, all of this will take a year and a half to materialize, after all, the next Mars launch window alone will not be until November 2021. Because of the increased speed of the Martian spacecraft, the Mars launch window will be delayed for a while.

After all, when the Mars launch window was calculated in the past, it was calculated based on the seven months of the Mars spacecraft's flight, and that time window was in July 2011. Now the speed of the Mars spacecraft has been greatly improved, and it will take less than two months to reach Mars, so this launch time window must be postponed, otherwise according to the previous launch window, when the Mars spacecraft arrives at the designated location, Mars has not yet flown over

Now Tang Feng and they are about to start the real moon landing operation. Of course, in order to test the functional indicators of the "Kunpeng", the "Kunpeng" also participated in the lunar landing operation this time.

The "Eagle Falcon" is still made by Han. is coming to serve as the commander of the Frenchman Jean. Renault served as the pilot of the "Falcon", and the Englishman Jimmy. Johnson was a crew member on the Falcon.

The "Kunpeng" was developed by the Russian Alexander Anderson. Comrade Borisov served as the commander, and the Canadian beauty Emily. Singh served as the pilot of the "Kunpeng", and the American Bob Singh served as the pilot of the "Kunpeng". Arnold is the crew, and as for Tang, play soy sauce

In accordance with the predetermined procedure, the two landing spacecraft detached from the Martian spacecraft in turn and began to cut into the landing orbit at a certain angle.

Because the gravitational pull of the Moon is much smaller than that of the Earth, both landing spacecraft flew with considerable ease. Whether it is adjusting the falling attitude in the air or igniting the main recoil rocket at the end, it is much easier than on Earth, and the fuel consumption of the two landing ships is also very small.

Dr. Schmitz, who is far away in the ground control center of the Princess Belle Island Space Center on Earth, immediately calculated how much fuel the two landing spacecraft would consume if they landed on Mars, and the final result was naturally very satisfying.

In other words, whether it is the "Eagle Falcon", which has carried out three moon landing operations, or the "Kunpeng", which has carried out the landing mission for the first time, the performance is almost perfect.

When the two landing spacecraft landed safely at the predetermined location, Tang Feng, who was wearing a new spacesuit, or simply called a "Mars spacesuit", was the first to step out of the "Kunpeng".

This Mars spacesuit is a new generation of spacesuit specially developed by Rockwell International commissioned by Star Exploration Company, and is specially prepared for astronauts landing on Mars.

You must know that the first moon landing and the second moon landing of Star Exploration Company are the kind of extravehicular spacesuits that are still used in the fourth generation. This kind of extravehicular spacesuit, which costs up to 12 million US dollars, has a dry weight of up to 90 kilograms alone, and it is not that it is to act in space or on the moon, so this extravehicular spacesuit will not bring much weight to the astronauts.

But if you wear this spacesuit to land on Mars, I'm afraid the astronauts will have nothing else to do, and the weight of this spacesuit alone is enough to make the astronauts exhausted.

The gravitational pull of the Moon is only one-sixth that of the Earth, so the 90-kilogram spacesuit weighs almost 15 kilograms on the Moon, which is enough for astronauts to bear. But the gravitational pull of Mars is more than one-third of that of the Earth, and if you wear this kind of spacesuit, it is equivalent to carrying more than 30 kilograms of weight on Mars.

Maybe it's okay for a short time, but if you are active on Mars for a long time, you can't exhaust the astronauts to death?

Therefore, as early as after the first moon landing, Tang entrusted Rockwell International to develop a new generation for Star Exploration, that is, the fifth-generation spacesuit. After spending almost $300 million in research and development expenses and more than three years, this new Martian spacesuit has finally been successfully developed.

The new Martian extravehicular spacesuit, which weighs only 41 kilograms on Earth, has an internal life-support system that allows an astronaut to continue to move outside the space for more than 16 hours. Crucially, the new extravehicular spacesuit can have an internal pressure of up to 0.76 atmospheres, far exceeding the 0.54 atmospheres internal pressure worn by astronauts during the last two lunar landings.

In the past, it was a very troublesome and dangerous thing for astronauts to go out and enter the capsule, and if one did not pay attention, there was a great possibility of inducing "caisson disease" in astronauts, and in serious cases, it could even threaten the lives of astronauts.

So in the past, when entering and exiting the cabin, it took at least a few hours to prepare, and you also had to inhale pure oxygen. However, after the adoption of this new extravehicular spacesuit, because of the increase in the internal pressure of the spacesuit, the astronauts can enter and exit the capsule very freely, without having to prepare for several hours in advance and inhale pure oxygen.

The internal pressure of 0.76 atmospheres is only equivalent to the air pressure on the top of a high mountain at an altitude of 2,200 meters on the earth, which is absolutely tolerable for human beings, and this air pressure is enough to prevent the occurrence of "caisson disease".

However, the cost of such an extravehicular spacesuit is far more than the one worn during the previous two moon landings. The cost of such a spacesuit is as high as $25 million, more than double the cost of the previous generation.

However, in order to protect life, even if the cost is high, Tang Feng is willing to spend this money to equip such a spacesuit.

Now, the seven astronauts led by Tang Feng have all walked out of the two lunar spacecraft in such spacesuits and began to move on the surface of the moon. (To be continued.) )
