Voyage of the Stars

The departure of the first space mining robot awakened the Hope, which had been sleeping for thousands of years.

Before landing on the Danros 154-4 planet, humans first set the target on its satellite. The mining robot will conduct mining operations on this irregular satellite that is only more than 200 kilometers away. Then, through a transport boat, a Ships of ore are transported to the Hope.

Then the engineering workshop on the Hope will operate at full capacity, continuously producing various items for mankind. At the same time, the battleship construction plan was also restarted.

Everything is waking up.

At about the same time, in a small conference room, Yue Yuan was exchanging opinions on landing matters with more than a dozen scientists and related geological workers.

"Currently, judging from the planet we have observed based on satellite images, the planet's surface is mainly composed of ravines and low hills, and no other tall mountains or peaks have been found. Well, several planetary evolution experts seem to have something to say. Say. But please hear me out."

Looking at the hesitant planetary evolution expert, the forty-year-old female geologist continued: "Because of the small number of satellites, we have not yet obtained comprehensive geological data for this planet, but As far as the situation captured so far, I think there are two things that are a bit strange. Look at this picture."

The geologist pressed the button in her hand to send a signal to the big screen. After the picture was displayed, she pointed at the picture: "Look, the dark place under the mound looks like a cave, something like a cave. Four have been discovered from satellite images. This is the first point. The second point is that our satellite spectrometer discovered this."

Looking at the changes in the picture on the screen, he found that this picture was different from the others. It was a bit similar to infrared imaging, but different, so Yue Yuan asked: "What is this?"

"The mine, or the exposed metal mountain, contains various elements such as iron, aluminum, tungsten, manganese, and titanium, and the amounts are very large. From preliminary analysis of the spectral data, we believe that their purity is very high! Do you think a planet Is it reasonable to have so many open-pit mines in the world?”

An astronomical research expert nodded and said: "From the perspective of planetary evolution, because the temperature of the planet reaches an extremely high level in the second stage of its evolution, which is the differentiation stage, in this case it is equivalent to a molten The planet is affected by gravity, and its heavy elements should be deposited in the underlying rock layers. From this perspective, it is indeed unreasonable.

However, there are also special cases. If it is hit by a massive celestial body after cooling, it is possible that the heavy metal elements inside it will be thrown out of the geological outer layer, such as our earth.

And have you discovered that this planet does not have a massive satellite, so we cannot rule out the possibility that during the formation of this planet, due to various complex factors, its satellite collided with it, and then After a long evolution, they merged together, and such a powerful impact may throw heavy elements into the outer geological layer of the planet. "

"What about these caves? How to explain them?" The female geologist switched the picture to the previous one. She felt that these large caves were very unusual. However, since they were only shown in satellite images, there was too little data to explain them, but they Keep expressing your concerns.

"Well, it is normal for a planet to have structures such as caves. It shows that it has a hot core and there are geological movements."

"No, I don't think it's that simple."

"Then what do you mean, it can't be an alien cave, right? The atmosphere of this planet doesn't even have oxygen, and there are poisonous gases such as carbon monoxide and sulfur dioxide. It's unlikely that there is life, let alone aliens." Another An expert shook his head: "Besides, we can't give up on landing just based on limited data guesses!"

"I didn't say give up on landing, I just think this planet is very strange. It is recommended to send robots to conduct preliminary exploration before landing personnel, and then conduct personnel landing after confirming that it is safe." said the female geologist.

The Hope had finally arrived here, so how could it give up, knowing that there were still so many exposed metal mines on this planet?

At this time, an expert suddenly said: "Is it possible that it is the cosmic Zerg?"

"You have watched too many science fiction movies! This planet is bare. Even if there is life, what do they eat? They can't eat dirt, right?" Someone immediately scoffed at this question.

Indeed, the so-called Zerg is also a living form, and to be a living form, it needs to absorb negative entropy. The average surface temperature of this planet is -118.3 degrees Celsius, which theoretically makes it impossible to have life.

Observed from satellite images, no ice layer was found on its surface, nor was there any sign of life.

"It's not impossible," the man muttered.

As soon as these words came out, the people who refuted him were speechless, and they couldn't even talk about science.

Seeing that the conference room looked like it was about to start a quarrel again, Yue Yuan waved his hands and said: "Then let's do it. First, let the unmanned detector carry the landing craft to land. The location will be near the caves and exposed mines. After confirming safety, personnel will be logged in."

After what the female geologist said, he felt a little strange.

Moreover, according to the normal landing procedures, unmanned detection should actually be carried out first. However, humans were really too excited to formulate a plan of direct personnel landing.

It took thousands of years to arrive at such a promising land rich in materials. Everyone was excited, but not everyone lost their minds because of the excitement.

The experts have not forgotten to hold a seminar before landing.

Yue Yuan was very satisfied with this.

The login has not officially started yet. There is no problem in temporarily adding a normal procedure. At most, the first batch of people who are ready to log in will have to wait ten days and a half.

Yue Yuan did not need to arrange the specific details personally. He only needed to tell his assistant Long Xiaolin and she would arrange everything.

You have to be careful, you have to be cautious.

The people who make up the current Callisto base are not a group of prisoners, nor a group of loose people put together temporarily, but a group of people who have inherited all the systems and civilization information of the Callisto base. They are organized and disciplined. They used to be flower growers. The set of space exploration procedures and lessons are still clearly written in the central computer.

Under normal circumstances, one should follow procedures and use scientific steps to treat anything encountered in the universe, even if it is landing, something that humans are already familiar with.

So first, the unmanned detector needs to land, then investigate the suspicious location, then sample the suspected target ore and return it, and then analyze the sample

After this, the planet will be evaluated and analyzed based on the analysis results, and only then can large-scale landings of personnel be carried out.

There are many types of unmanned ground detectors, including wheeled detectors with solar panels, tracked detectors, and small unmanned aerial vehicles.

Since the planet's atmosphere is thin and unsuitable for propeller-type drone operations, this unmanned exploration was mainly based on ground vehicles.

In order to cooperate with unmanned ground probes, Hope launched several artificial satellites to the Ross 154-4 planetary orbit. In addition to serving as signal relays, these satellites are also equipped with CCD stereo cameras.

This kind of camera can perform push-broom scanning of ground targets when an artificial satellite is flying, thereby obtaining three different angle images of the same target on the surface. These three angle images are the subsatellite point, that is, the front view, and the front view. View 17°, backsight 17°.

After obtaining the three two-dimensional original data, the image is corrected by radiometric calibration, that is, the gray value of the target image is converted into the actual brightness value of the target, and then combined with the satellite position and attitude during imaging, a three-dimensional stereoscopic image of the surface target is reconstructed. .

This will provide more detailed data for target detection.
