My biological black technology

"continue!"

The operator follows instructions and switches pictures step by step, frame by frame.

The control center once again fell into a tense atmosphere.

"I hope the alien creatures from 100,000 years ago would have vision similar to ours."

"hope so."

A few minutes later, the 100 pictures have been switched. There are many defects and missing data in these 100 pictures. However, looking at the overall picture, the changes in the astronomical star diagram can still be distinguished.

However, the difference in image changes is very small, which means that the amount of information that can be obtained is very limited.

The control center became even more nervous.

Cheng Xiang took a deep breath and said, "Continue!"

A few minutes later, another 100 pictures were viewed.

"It seems that the frequency of this projection is about 120Hz." Cheng Xiang said.

Ding Qing nodded in agreement, "Absolutely. Although it's a bit higher than 60, but fortunately it's not too high."

"At 120Hz, we have about 10 seconds of images."

"It's quite a lot. I just hope that it won't just be this starry sky all the time, but at least I can see something else." Cheng Xiang joked nervously to lighten the atmosphere.

"I hope so." Ding Qing said slowly.

"continue!"

"good!"

The pictures continue to switch down, and the pictures go through frame by frame.

Every time dozens or hundreds of pictures pass, the image changes slightly. These changes made the atmosphere at the scene even more tense.

"Look, what is that!"

In the picture, a new discovery suddenly appeared.

As the frames continue to roll, new discoveries become more and more complete, and a light blue crescent moon appears in the starry sky.

"very beautiful."

"Like a blue moon."

Seeing this, Cheng Xiang explained with a smile: "If my guess is correct, it should be the earth. In space, the light reflected by the earth is light blue."

"The Earth's orbit is inside Mars, so it's not easy to capture such a scene."

"If you are interested, you can take a look at the pictures on display at the space center. There are similar pictures among them, and there are even better ones. On Mars, if you choose the right time, you can not only see the earth, but also the earth. To the moon.”

After Cheng Xiang's explanation, everyone understood. On the one hand, they were impressed by the magnificence of the starry sky, and on the other hand, they were also impressed by Cheng Xiang's vast knowledge.

They were really convinced that a biology student was so proficient in astronomy.

The camera is moving. Moreover, the perspective gradually changed from looking up to looking down, and the crescent moon of the Earth has almost disappeared on the other side of the picture.

"There are less than 3 seconds left. I hope I can see the edge of Mars."

"It's coming soon. At the current speed, there should be hope!"

"It should be okay. It would be a shame if it was always the starry sky!"

The number of remaining image frames decreases as time goes by.

At a frame rate of more than 100 frames, the camera moves slowly.

In the blink of an eye, another 100 pictures passed.

The lens was pulled down a little again. At this time, there seemed to be a slight change in the picture. A silver-white arc outline seemed to appear on the edge of the picture.

This newly emerged silhouette immediately attracted everyone's attention.

"what is that!"

"Look!"

"what is that!"

In the deep sky, another arc suddenly appeared. This change excited everyone who had been staring at the same starry sky for almost an hour.

Cheng Xiang and Ding Qing were both excited. The more discoveries in the picture, the greater the amount of information provided.

"The location where this appears should also be a celestial body."

"With this size and brightness, it should be a satellite of Mars."

"I just don't know if it's Phobos." Cheng Xiang said quickly.

Mars has two satellites, Phobos and Deimos.

Cheng Xiang frowned, staring at the picture and thinking carefully, trying to find more information from the picture.

The operator is still playing the pictures slowly.

Frame after frame passed, this newly appeared celestial body appeared in more and more parts. The more parts it appeared, the more Cheng Xiang frowned. As time passed, almost everyone in the research room noticed something strange.

This silver-white thing looks so familiar.

So familiar that they can relate to it without even thinking about it.

"Why does this thing look so much like our moon?"

"It does look very similar."

"Maybe it's just a similarity. Just now Cheng Suo also mentioned that there are two orbiting satellites on Mars, Phobos and Deimos."

"Perhaps, this is one of them."

"After all, the moon is also a satellite of the earth. They are both satellites, maybe more or less the same?"

Everyone was watching and talking carefully, but Cheng Xiang had no time to take care of it at this time. He didn't hear what the people in the control center were saying at all. He only saw the increasingly complete silver-white celestial body in the picture.

Ding Qing stood next to Cheng Xiang and felt something was seriously wrong at this time. Cheng Xiang's expression became more and more serious, with shock and disbelief in his eyes.

In her impression, Cheng Xiang was always calm and composed when facing anything. Take another look at the new celestial body in the picture and combine it with the following discussion.

An idea came to Ding Qing's mind that even she couldn't believe, "Is it possible that there is really something wrong with this new celestial body?"

"And the problem is... big?"

"This...could...not be possible." Ding Qing did not dare to continue imagining, "No, it's impossible, that would be...too ridiculous." Ding Qing couldn't help but swallowed.

A few minutes later, all the pictures finished playing and the picture stopped. The edge of Mars appeared vaguely on the edge of the picture, and above the edge, a round silver-white celestial body hung high in the starry sky.

Cheng Xiang's eyes were fixed on the silvery-white celestial body that finally appeared.

After several hesitations, Ding Qing finally asked tentatively, "Mr. Cheng, you...did you find something...wrong?"

"Is this round celestial body Phobos... or Deimos?" Ding Qing did not dare to directly state her guess, it would be too ridiculous.

"Phobos?"

"Deimos?"

Cheng Xiang shook his head vigorously. When shaking his head, his eyes did not leave the silver disk in the picture, "This is not Phobos, and it is definitely not Deimos!"

"Phobos is potato-shaped, with an average orbital distance of about 9,378 kilometers from Mars. The distance between Phobos and Mars is also the shortest among all satellites in the solar system and its host star, only 6,000 kilometers from the surface of Mars. It is one of the smallest satellites in the solar system and one of the least reflective objects in the solar system. The shape and brightness of the one in the picture are not right."

"Similarly, Deimos is very small, with an average radius of 6.2 kilometers, and its distance from Mars is 23,460 kilometers. Therefore, the size and brightness do not match up."

"In my impression, if there is a celestial body that matches the picture in front of me, there is only one that can match this one." Cheng Xiang spoke very slowly, and his slowness was full of dignity. Ding Qing's heart skipped a beat when she heard this.
