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

Chapter 659 Canopy-4

Beijing, United Mining Headquarters.

The lively scenes of the Tianmu-3 mission are once again reproduced here, but the difference from last time is that there is a more tense and depressing atmosphere.

The current CEO Wu Yi stood on the podium with a serious face, which made Zhu Bingguang and Yang Xinjun sitting together below feel anxious.

The results of field experiments on space cement and 3D lunar soil printing technology have been sent back. Although the samples have not yet been sent back, the testing at the Yushu base has been very detailed and provided sufficiently convincing arguments.

After more than two months in the extreme alternating hot and cold environment of the moon, the pavements manufactured by both technologies have withstood the test. Although some parameters are higher and lower, they are generally similar and exceed the minimum requirements.

There is not much difference in quality, so the fate of the two technologies is determined by convenience and cost. Time and energy are also very important resources on the moon.

The judging panel, composed of personnel from the Aviation Development Commission and Xinyuan, completed the final decision late at night and will soon announce the results.

Yang Xinjun, who was crossing his hands vigorously, glanced at Lin Ju, who was looking at ease beside him. The latter went to visit the tomb early in the morning and looked a little absent-minded.

"Based on the joint review of 22 aerospace experts, we confirmed that we will start the lunar highway construction plan within 6 months, and after careful discussion, we will select the most suitable party from the two bidding groups."

Wu Yi didn't speak very fast. He paused here and glanced at the restless two people, then calmly read out the final result:

"After comprehensive comparison in many aspects, we believe that space cement technology is more suitable for the lunar highway construction plan, and hope that the Beijing Hangzhou University team led by Professor Yang Xinjun will undertake the research tasks of related equipment and construction plans, and complete the first lunar highway with quality and quantity. Basic road construction plan!”

Yang Xinjun, whose whole body was tense, had already relaxed when he heard the words Space Cement. After the words were finished, his whole body relaxed, and then he slumped down on the chair and smiled stupidly into the air.

With a construction plan of three hundred kilometers and led by them, how many key technologies will be mastered at once?

This is a completely new field of research, and the benefits gained by the first person to eat it are unimaginable!

Warm applause immediately erupted in the venue, congratulating each other on the official launch of the largest infrastructure project on the moon.

The only ones who lost were Zhu Bingguang and his assistants. The 3D lunar soil printing technology was first eliminated within the space agency, and also lost the second time it participated in the competition. Is there really a mistake in the technical route?

He was lost in thought until the applause ended, and he didn't even hear Shen Zuozhou calling his name.

"Professor Zhu, Professor Zhu Bingguang?"

"...Ah, I'm here, I'm listening."

Wu Yi on top had been replaced by Shen Zuozhou at some point. He did not hold a position in United Mining. Standing on top made Zhu Bingguang a little confused.

"Ahem, let me announce one more thing:

Because of the good performance of 3D lunar soil printing technology in terms of plasticity and compatibility with complex surfaces, the Aerospace Development Commission hopes to use this technology for the development of the lunar underground and the construction of the outer protective layer of the permanent base, and will officially launch it within three months. "

Due to the special environment of the moon and the different structures of basic components, the construction difficulty of space cement is actually higher than that of 3D printing technology in terms of forming complex surfaces.

Besides, Lin Ju had no intention of choosing one or the other. Both technologies needed to be developed as reserves. The huge lunar project could not only support one route.

It is divided into two according to its characteristics. The cost of 3D printing technology is higher, so it is used in the construction of smaller residential areas to make the best use of everything.

The sudden turn of events stunned both Yang and Zhu. Yang Xinjun was the first to react and congratulate the latter:

"Okay, Lao Zhu, you can move faster than me."

"I... really didn't expect..."

Zhu Bingguang just sighed in the end. In any case, his long-term efforts finally paid off, and that was enough.

Both teams achieved a happy ending, and Wu Yi stepped forward again and read out today's main topic:

“After two months of compilation, all the data obtained by the Tianmu-3 mission has been analyzed. According to the Yushu mine development schedule of United Mining, I announce that the Tianmu-4 inspection mission will be launched immediately from April 7.

This mission mainly includes exploring the hydrogen bomb test explosion point, confirming the test explosion yield and test objects. It is tentatively scheduled to conduct the reporting mission on May 9, and complete the post-explosion effects summary to provide information for the formal large-scale mine development mission of Tianmu 5. in accordance with.

There are a total of 27 members in the Tianmu-4 inspection mission, which is expected to require five to seven landing missions. Now, please let the winning bidder of the mine blasting project speak in order! "

…

The Tianmu 4 mission was mainly about blasting. Because it involved a lot, the preparatory meetings were very lengthy. Lin Ju left quietly not long after, but he did not go back to the hotel but went straight to the Aviation Development Committee.

As time enters April, the flashpoints of various tasks have begun to gather.

The Long March 18 rocket has begun preparations for launch again and is scheduled to be launched on May 7, which is still 32 days away.

Just like its predecessors, Jiuzhang's sister ship Zhurong also flies to Yizhou and then travels by sea. It is expected to arrive in Qiongzhou a week later for the combined launch.

Tianwen 1, 2, 3, and 4 are four consecutive missions of the same detector. They will launch a new one every two days on April 29, May 1, 3, and 5 respectively. Far-2 rocket.

Two were launched in Jiuquan, with the Beijing Command Center in charge, and two were launched in Qiongzhou, with Xinyuan in charge, to reduce the pressure on the command team.

But the busiest thing should be the Yuanwang fleet at sea, which needs to continuously monitor the rocket flight trajectory.

The last "Super Big Cup" Typhoon is scheduled to be launched on May 22 due to its complexity, and is not expected to leave the factory before May 5.

However, due to the abnormal acceleration of its nuclear power and the lack of need to slow down on Mars, Typhoon arrived at Mars incredibly quickly. It could complete the journey in just 40 days. It would fly past Mars at high speed around July 2 and release the probe's At the same time, it uses its gravity to continue accelerating, and then uses Jupiter's powerful gravitational slingshot to accelerate one last time. Soon after, it will begin to decelerate and park into the orbit of Saturn.

It takes more than 4 months from Mars to Jupiter. The acceleration period from Jupiter to Saturn will last for 3 months. The remaining 3 months need to be used to slow down, and it will take exactly 12 months to reach Saturn.

The missions of Tianwen 1 to 5 will take about 6 months, and they will not reach Mars until mid-October of the second half of the year, which is far behind.

Even in theory, "Lihuo" should arrive "simultaneously" at that time, but the base planned to have it appear in August or September, claiming that it was accelerated a little by the ion thruster on the detector.
