I ask you to build tractors, but you build rockets?

After the Shuguang and Tianmu projects had a smooth start and achieved great success, the ambitious Mars project became the next goal pursued by astronauts, and they immediately began to expand the previous "Tianwen" series of plans.

The previous four Mars rovers from Tianwen 1 to 4 remain unchanged, and the planned scientific payloads have entered the manufacturing stage, so there is plenty of time.

Then at a recent regular meeting, someone proposed launching the Tianwen-25 mission.

The proposal of this mission is based on three emerging technologies: humanoid robots, fully automatic fuel synthesis systems, and the "Nine Chapters" spacecraft.

First, there are more than a dozen modular self-propelled equipment that are used to verify the moon in the ice and snow. They are programmed to simulate lunar conditions as much as possible, and even need to be regularly sprinkled with simulated lunar dust to conduct all-round verification work.

So far, the test has been very successful, all equipment works well, and the synthesis amounts of hydrogen, oxygen, and methane are also fully up to standard.

This system only needs a few minor improvements to work on Mars, so it can be regarded as an increase in the progress of the Mars base construction.

Then there was the "14" robot that had been sneaking around on the moon. The ground was actually a little worried when it was decided to board the Dawn-3 spacecraft.

After all, the essence of "14" is a modified robot No. 2 put on a simple spacesuit. It was improvised and had many shortcomings. However, it is still active on the moon and actively exploring.

14 The main job now is to collect information about the cave where Artemis 2 crashed, and conduct inspections with an explorer. The latter has been modified to charge itself with the isotope battery it carries. It has already explored The cave, which is more than ten kilometers long and 150 meters deepest, has sent back a lot of precious data.

Since the 14 that was put on the shelves can work so well, will it be possible to use robots on a larger scale on Mars, which is more "mild" than the moon?

Therefore, Mission 5 is to send more than 10 robots and equipment weighing at least 50 tons, including fuel production, 3D printing and other multi-functional equipment to the surface of Mars, so that the robots can build Mars outposts and accumulate supplies in a long few years. Reduce preparations for manned exploration.

After all the carriers were considered, the XH40 was used, but the maximum take-off mass was also limited to 200 tons. In this way, while other designs remained unchanged, it could still have an up and down transport capacity of 60 tons, enough to accommodate the required equipment and robots.

This is just enough for the Xinyuan 4 rocket to fly to Mars and land safely, and it also has the ability to carry a small amount of payload into orbit again. If the spacecraft that lands on Mars in the future fails, this spacecraft can continue after adding fuel. Send people up.

The Tianwen-5 plan can be prepared before the window period. What is needed is either already available or can be completed immediately. The feasibility is very high.

But this also means a significant increase in task costs, as well as risk issues.

There has not yet been a successful Mars mission in China. No probe has ever touched the orbit of Mars. It was such a big deal from the beginning. What if it fails?

The Aviation Development Committee is currently discussing this issue. If it is to be implemented, then the No. 5 plan must start preparations immediately before it is too late. If it is delayed, the window period will be exceeded, and a decision needs to be made as soon as possible.

Academician She's inner objections still prevailed. The proposal of Task No. 5 has shown that many people within the Aviation Development Commission have developed the idea of ​​​​"go big and fast" and "reach the sky in one step". He is very clear about the consequences of this trend of thought prevailing. Squeezing is not a bad thing.

And now that he is already ahead enough, in his opinion, there is no need to rush this time. Isn't there another window period in 2020?

The third window period of 2022 is only five years away now. It is fast enough for China Aerospace to land on the moon five years after the moon landing. He believes that Aramco will need at least 10 years.

As for Lin Ju's opinion, he didn't even have to think about it. The radicals on the Aviation Development Commission just let the wind out and he flew over. His attitude was already quite obvious.

Perhaps because the Tengyun project successfully made its first flight within the deadline promised by Serev, Academician She feels that there will be fewer and fewer "old aerospace" in the future.

…

Edo.

There were noisy sounds outside the hotel where the IAEA expert team was staying. Tomarsov, who was having breakfast, opened the curtains and saw a large group of people walking across the road holding promotional signs.

Tomarsov couldn't make out what they were shouting or their slogans, but he could barely see the picture on the big billboard at the front of the crowd. It seemed to have an airplane on it, and then there was a big red cross.

He called the waiter and said a few words, and the latter immediately trotted out. After a while, he came back and said something in Tomarsov's ear. The latter was stunned for a moment and then let out a scary laugh.

Others looked sideways, and Academician Zhou who was closest to him asked curiously:

"what happened?"

Tomarsov laughed so hard that he held his stomach and said:

"Zhou, do you know what they are protesting? They are protesting against the aerospace aircraft!"

"What? Why are you protesting against the aerospace plane?"

"Because they believe that the one that flew over a month ago was Tengyun, the aerospace plane is the source of all chaos, and it must pay compensation to the island country before it can fly."

"..."

Academician Zhou was also shocked and speechless by this strange reason. What kind of brain circuit is this?

In the end, he attributed this to the fact that the spirit of the islanders might not be normal to begin with, and he put it aside and got down to business.

"Yuri, what are the results of your calculations?"

"Oh, I think there shouldn't be much error. The equivalent of 150,000 to 200,000 tons is very suitable."

This is the same as his calculation. Academician Zhou nodded and said:

"Then let's make an official announcement as soon as possible. Our first phase of the mission has been completed."

What he and Tomarsov were talking about was the first air-explosion hydrogen bomb to be used on Fukushima. It was mainly for verification purposes, as long as the yield was sufficient.

Whether hydrogen bombs can effectively clean up nuclear radiation is only a possible guess, and there are many ways to clean up. Currently, there are two types that are considered feasible: one is that the high energy of the super-large-yield two-phase hydrogen bomb causes the decay of the ability to release radiation residue; instead, using Neutron bombs bombard radiation residue with a stream of neutrons to cause it to decay.

Only one test is enough for both solutions. After all, two-phase hydrogen bombs can also produce neutron jets.

And with the deepening of research, experts have almost determined the limit of the cleaning effect: in the short term, the radiation value rises to 10% of the level before the air explosion, but the radiation produced by the hydrogen bomb will quickly decay to the threshold acceptable to humans in one to two years. It can reduce pollution by at least 85%, and the feasibility of the technical solution can support specific tests.

However, in fact, when the expert team said that they would use hydrogen bombs to clean up radiation, the island government showed extremely strong opposition, but they did not dare to speak out, because when Nakayama asked John for his opinion, the other party's answer was "you must trust the judgment of the experts." .

Believe in a ghost!

These days, the expert group has been receiving the highest level of hospitality, not only staying in the best luxury hotels but also receiving personal services, just to make them change their minds.

On the surface, the expert team accepted all comers and seemed to have stopped their inspection work, but in fact they were collecting data and sending it back to their country for model calculations.

The purpose of this action of the IAEA is clear. How could it be possible to easily bribe a few experts?

I’m done, I’ll start increasing the code size tomorrow
