Xu Xingchen listened to Yuanwang No. 1's feelings and compared the situations of the two planets again, and immediately found that these two planets were really awkward...

If there were no guidance missions left by "they", Xu Xingchen would definitely feel very regretful about the state of these two planets, just like Yuanwang 1.

But when you have a mission, you will feel that they are specially prepared for themselves and the ship girls, the transformation objects used for the planetary environment transformation guidance mission.

Xu Xingchen recalled the technologies and equipment in the planetary environment transformation technology package that he obtained, and immediately found the corresponding transformation equipment and solutions.

The transformation of Planet II is to collect greenhouse gases to produce oxygen, collect excessive nitrogen to convert it into food and fertilizer, and generally reduce atmospheric concentration and temperature.

The transformation of Planet IV is to harvest ice to create a complete atmosphere, including greenhouse gases, nitrogen and oxygen, increase the overall temperature and melt the ice.

Then, both planets have to build their own biospheres. Since they are built from scratch, they can directly copy the ship girl star without worrying about biological invasion like the big moon.

In comparison, after the transformation of these two planets is completed, the conditions of Planet II will be better and more livable than the Great Moon.

Because gravity is slightly lower than that of the earth, but not particularly low, it will make people feel more relaxed and all kinds of machines without causing diseases and damage.

Although the area of ​​Planet IV is larger, its gravity increases by 20% compared to the Earth. Although this proportion is not very high, it will eventually give people the feeling of load-bearing activities.

After a very simple consideration, Xu Xingchen decided to choose Planet 2 as the mission goal of the environmental transformation mission.

The space base that he sent to the two planets, the part that went to Planet 2 was about to arrive soon.

After arriving, you can obtain detailed information and you can start preparing a renovation plan here.

Xu Xingchen was so focused in his heart that he briefly talked about his plan to Yuanwang No. 1:

"Sister Yuanwang doesn't have to regret that the planetary environment is not suitable for our lives, so we can transform it to the right one by ourselves.

"We think most planets cannot be as perfect as our home planet, and environmental transformation technology should be a must-have.

"These two seemingly regrettable planets can be used as our goal in practice, and they are likely to be specially prepared for us like this.

"We have mastered environmental transformation technology at the doorstep of our home planet, and we will be more confident if we go to other galaxies in the future."

Yuanwang No. 1 was stunned for a moment after hearing this, then slapped his palms with obvious exaggeration, and said with a self-deprecating smile:

"I'm thinking a little bit. The overly superior conditions of our galaxy, the existence of the natural and habitable planet of the Great Moon, has pushed my expectations for other planets too high..."

Xu Xingchen was also shocked. He had never seen Yuanwang No. 1's reaction.

This elder sister of the Yuanwang family has always looked like she was in control of everything. She always had a calm smile on her face and had never had too much fluctuations.

Yuanwang No. 1 really quickly returned to its usual state. She sighed and said with a smile:

"If it is put into the entire universe, the state of Venus, Mercury, Mars, or a completely desolate superplanet is the real normal.

"It is absolutely rare to place these two planets in the entire universe. A pure atmosphere dominated by liquid water and nitrogen is already in the past.

"If it is an ordinary space agency on Earth, if these two planets are discovered, it will definitely cheer and announce the world.

"The commander said it well. Environmental transformation is a very important technology. These two planets that are close to livable can be used as experimental fields for overall environmental transformation."

As Yuanwang 1 was talking, a flash suddenly appeared on the projection interface in the middle of the hall, and a notification jumped out at the same time.

And there were immediately cheers in the entire hall:

"It's here, it's here, it's finally here!" Gu Jing

"That flash is our space base!"

"The second planet space base successfully arrived at the orbit of Planet 2!"

"Entering the track, the track is about to begin!"

Yuanwang 1 also showed joy in his face, and immediately adjusted the picture in front of him, enlarging the picture of the second planet to the entire projection.

After clicking on the message notification, the flash turned into a square, an enlarged planetary space base.

This space base has been flying in space for five months and finally met the second planet that has turned around. This is one of the important reasons why Xu Xingchen rushed back.

Now in front of the model image representing the space base, a spiral orbit around the second planet appeared, which is the orbit that the space base is performing.

All programs are pre-set. If no exceptions occur later, you can just wait now.

Although the space base of the second planet is relatively traditional, it is only about the direct route to Neptune.

Compared with the common elliptical orbits that approximate the Homan transfer, the radius of the flight trajectory of the space base is still relatively small.

The acceleration when leaving the orbit of the ship girl star and the acceleration when entering orbit after arriving at the second planet are all very large.

Because the launch time is not in the appropriate window period, and we can only rely on greater speed to chase it.

When starting from the space base, the base was piled up with a large number of boosters like a rocket, and used these discardable boosters to push the base to a sufficient speed.

The built-in engine of the space base itself is only responsible for the acceleration (deceleration) of entry into orbit after reaching the target.

Even simple fuel consumption is still large, because the unusual satellites or small probes that need to enter orbit are space bases of more than 20,000 cubic meters.

The space inside the space base that should have been left empty is basically filled with fuel for slowing down.

When approaching the second planet, the space base turns around and starts to decelerate relative to the second planet (accelerate for the star system).

In a very outrageous squirting, the space base reached its junction with the second planet, about 3,000 kilometers above the planet.

After sweeping over the planet's orbit inside, and decelerating with the help of a gravitational slingshot, the speed was finally reduced below the escape speed.

However, the semi-major axis of the track is still extremely huge at this time, so the base engine continues to rush and continuously shorten the length of the base's operating track.

When the track height was shortened to 200 kilometers, the base finally shut down most of its engines on this almost quasi-circular low track.

This altitude has entered the edge of the rich atmosphere of Planet 2. If there is no power, it will slowly fall into the atmosphere, so a small number of engines are retained to maintain orbital height.

Then a large number of telescopic collection pipes extend out of the base to extract the atmospheric components at the edge of the planet's atmosphere.

The resource conversion equipment in the base will use the extracted atmospheric components as raw materials to convert them into resources used by ship girls.

Then through manufacturing equipment, resources are converted into fuel for rocket engines and charged into all functional modules of the base.

After filling all the module fuel tanks, the space base will accelerate the lifting track again and enter a relatively stable orbit operation of about 500 kilometers.

Then the base gathering automatically disintegrated and transformed into 64 giant cube satellites with a side length of 16 meters, and began a comprehensive personal inspection of the second planet.

At the same time, small ground detectors began to be deployed to enter the interior of the second planet's atmosphere and the surface of the planet to obtain more direct samples and data.
