Beijing, United Mining Headquarters.

Once again, the lively scene of the Skycanopy 3 mission is reproduced here, but unlike last time, there is a more tense and oppressive atmosphere.

The current CEO Wu Yi stood on the podium with a serious face, which made the hearts of Zhu Bingguang and Yang Xinjun, who were sitting together, hang.

The results of field experiments with space cement and 3D lunar soil printing technology have been returned, and although the samples have not yet been sent, the tests at the Yushu base have been detailed and provide enough convincing arguments.

After more than two months of alternating hot and cold conditions on the Moon, the pavement created by both technologies has withstood the test, and although some parameters are high and low, they are generally about the same, exceeding the minimum requirements.

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

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

Yang Xinjun, who crossed his hands and forcefully glanced at Lin Ju, who was at ease with the old god on the side, who went to sweep the tomb early in the morning and looked a little absent-minded.

"Based on a joint review of 22 astronauts, we confirmed that the Lunar Highway construction program will be launched within six months, and after careful discussion, the most suitable party will be selected from the two bidding panels."

Wu Yi's speed of speech was not fast, and he paused here to scan the restless two people, and calmly read out the final result:

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

Yang Xinjun, who was tense all over, had already relaxed when he heard the space cement, and his whole body was relaxed after the words ended, and then he slumped in his chair and smirked at the air.

A full 300-kilometer construction program, and still led by them, how many key technologies will be mastered at one time?

This is a completely new field of study, and the benefits obtained by the first person who ate crabs are unimaginable!

The venue also burst into warm applause, congratulating the official launch of the largest infrastructure project on the moon.

The only thing that is lost is Zhu Bingguang and his assistants, the 3D lunar soil printing technology was first eliminated within the space agency, and the second time to participate in the competition, is it really a mistake in the technical route?

He was distracted until the applause ended, and he didn't even hear Shen Zuozhou shouting his name.

"Professor Zhu, Professor Zhu Bingguang?"

“…… Ah, I'm here, I'm listening. ”

Wu Yi above doesn't know when he has been replaced by Shen Zuozhou, he does not hold a position in United Mining, standing on it makes Zhu Bingguang a little confused.

"Ahem, let me announce one more thing:

Because of the good performance of 3D lunar soil printing technology in plasticity and complex surface compatibility, the Aviation Development Commission hopes to use this technology as a protective layer for the development of the moon's underground and the construction of the outer protective layer of the permanent base, and it will be officially launched within three months. ”

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

Besides, Lin Ju didn't plan to choose one or the other, both technologies had to be developed as reserves, and the huge lunar project could not afford more than one route.

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

The sudden turn of events made both Yang and Zhu stunned for a moment, and Yang Xinjun was the first to react and congratulate the latter:

"It's okay, Lao Zhu, you're moving faster than me."

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

Zhu Bingguang only sighed in the end, no matter what, the long-term efforts have finally paid off, and this is enough.

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

"After two months of summarization, all the data obtained by the Tianmu 3 mission has been analyzed, and according to the Yushu mine development schedule of United Mining, I announce that the Tianmu 4 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 object, tentatively scheduled to report the task on May 9, and completing the summary of the effect after the explosion, so as to provide a basis for the official large-scale mine development task of Tianmu 5.

There are a total of 27 members of the Tianmu No. 4 inspection mission, and it is expected that five to seven landing missions will be required. ”

……

The mission of Tianmu No. 4 is mainly based on blasting, because it involves a lot of preparations, so the preparatory meeting is very lengthy, Lin Ju left quietly not long after, but did not return to the hotel but went straight to the Aviation Development Committee.

Fast into April, and the flashpoints of various missions have begun to concentrate.

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

Like its predecessors, the sister ship of the Jiuzhang Zhurong, it also flew to Yizhou and then sailed by sea, and is expected to arrive in Qiongzhou for a combined launch in a week.

Tianwen-1, 2, 3, and 4, four consecutive missions of the same probe, will launch a Xinyuan-2 rocket every two days on April 29, May 1, 3, and 5 respectively.

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

However, the busiest should be the long-range fleet at sea, which needs to continuously monitor the flight trajectory of rockets.

The last "Super Cup" Typhoon, because of the complexity of the scheduled launch on May 22, is expected to leave the factory before May 5.

However, because of its nuclear-powered metamorphosis acceleration and the fact that it does not need to slow down on Mars, the Typhoon arrived on Mars in an astonishingly fast time, completing the entire journey in just 40 days, passing Mars at high speed around July 2, releasing the probe while using its gravitational pull to continue accelerating, and then using Jupiter's powerful gravitational slingshot to accelerate one last time, and soon after that it will begin to slow down and dock into Saturn's orbit.

It takes about 4 months from Mars to Jupiter, the acceleration from Jupiter to Saturn lasts for 3 months, and the remaining 3 months need to be used to slow down, just 12 months to reach Saturn.

The Tianwen-1 to 5 missions will take about 6 months, and they will arrive on Mars after mid-October in the second half of the year, which is far behind.

Even theoretically, the "Departure from Fire" would have to arrive "synchronously" at that time, but the base planned to make it appear in August or September, and claimed to have accelerated it a little bit with the ion thrusters on the probe.
