"Okay, we're free." After the communication, the girl said happily to Logic.

"Yes... I'm free." The logic said meaningfully.

Didi! Didi...

The sound of electromagnetic communication suddenly sounded in the UFO of Tomorrow.

"Hello, two, I am the captain Yu Yifeng. I will open the isolation wall for you. At that time, you can see the universe directly from the window. Please don't move around. The universe is very dangerous. Please wait and wait to arrive at Mars."

"I know." Logic said calmly.

The days that followed were full of boredom. The girl held her smartphone-like thing all day long, and didn't know what energy it used to support it for so long.

But the comfortable days are over.

Just as they were about to approach the orbit of Mars, Deep Space detected that two asteroids collided together on their necessary path.

There is no sound in the universe, so you can only see a trace of light.

Fortunately, the two asteroids are not big, but even so, the fragments generated are very threatening, and some of them are even attacking the Underworld of Deep Space.

Didi! Didi...

"We found some asteroid fragments, logic, do you have any good suggestions?" Yu Yifeng's voice rang out in Tomorrow.

"You first use a micro nuclear bomb to bomb the dense asteroid fragments, and then use a laser weapon to smash the asteroid fragments in the straight line. The next one is left to us. Please give us the authority to use the weapon." Logic said.

"Okay." Yu Yifeng pondered for a while and agreed.

Next, Logic sat on the operating table, while the girl sat next to her staring at the asteroid fragments on the screen in front of her.

In the number below the deep space... Yu Yifeng stared at the asteroid fragment belt on the screen. When the distance was perfect, he suddenly pressed the launch button, and the two miniature nuclear bombs instantly flew towards the two asteroid fragment belts.

As for the Underworld and Tomorrow, Hope quickly began to slow down.

After reducing to the predetermined speed, the three UFOs are arranged in the formation.

The general and a team member operated the Hope number remotely, Yu Yifeng and another team member operated the Underworld number in Deep Space, while Logic and Girl operated the Tomorrow number.

The girl was a little excited, and looked at the asteroid fragments on the screen with a nervous look, waiting for Yu Yifeng to give the order.

Two miniature nuclear bombs exploded quickly, and the light generated was transmitted. Yu Yifeng ordered "Gradually restore navigation speed and fire at will."

The girl was waiting for this sentence. Suddenly, a laser light was launched from the Tomorrow and shot rapidly towards the nearest asteroid fragment.

The next second, the girl's smile froze on her face.

Her laser greeted the asteroid fragments and flew into the vast universe.

"I Cao!" The excited girl burst out and sweared, looking at the logic, shooting one by one accurately. She had already cleaned up about one percent of the asteroid fragments.

The girl suddenly felt unyielding.

"Du Lei Lou Mother!" The girl shouted loudly, almost frightened the logic and shot the laser light into the deep space.

The laser ejaculated for no money, but the girl was just a girl in her twenties after all, and could only get one shot in five shots.

After a while, Yu Yifeng's helpless voice came from the tomorrow account.

"I said Miss, you're wasting so much energy, it's hard for us to explore on Mars."

The girl stuck out her tongue and returned, "I know, I know, can't you shoot far if I'm close?"

After saying that, the girl picked up those closer shots, and the effect was better with just one shot.

Two shots can hit one.

However, this scared Yu Yifeng and the others into fear.

I was afraid that one would miss it and hit it.

However, there are not many asteroid fragments, so the logic just keeps its eye close to it. If the asteroid is too close, he will take action.

In this way, all the threatening asteroid fragments were wiped out, and everyone except the girl was shocked and sweated.

"Hahaha, it's so fun." The girl had a lot of fun.

Logic wiped the sweat from his forehead and looked at the girl helplessly.

Are you here to play or witness history...

It seems to be different from what I told me before coming.

The three UFOs quickly approached Mars and successfully entered its orbit, and entered the interior of Mars with gravity.

"Wow!" the girl sighed at the vast fiery red earth.

"Do you know Mars?" Lu Zhi asked with a thrilling heart when he came here for the first time.

"I don't understand." The girl shook her head.

"Then I'll give you some science." Logic said.

"Mars is one of the eight major planets in the solar system, the fourth planet in the solar system from inside to outside. It is an earth-like planet with a diameter of about 53% of the earth and a mass of 11% of the earth. The axis of rotation is inclination and rotation periods that are similar to the earth, and the revolution cycle is about twice the time of the earth's revolution. The orange-red appearance is hematite on the surface, that is, iron oxide. In ancient Chinese books, Mars is called "Yimer Star", and in ancient Western Western, that is, ancient Rome called "Marces of War".

"Mars is basically a desert planet, with surface dunes, gravel and only a small amount of stable liquid water. The atmosphere dominated by carbon dioxide is both thin and cold, with sand and dust suspended in it, and dust storms often occur every year. The poles of Mars are all filled with extreme crowns composed of water ice and dry ice, which will grow with the season."

Compared with the Earth, Mars is less active in geological activities, and most of the surface landforms were formed during the more active periods in ancient times. They were densely packed with craters, volcanoes and canyons, including the highest mountain in the solar system: Mount Olympus and the largest canyon: Mariner Canyon. Another unique topographic feature is the obvious difference between the northern and southern hemispheres: the south is an ancient, crater-filled highland, and the north is a younger plain.

Mars has two natural satellites: Phobos and Phobos, which are irregular in shape and may be captured asteroids. On Earth, Mars can be visible to the naked eye, with the highest brightness up to -2.9, and among the eight major planets, they are darker than Jupiter and Venus.”

The logical voice was vaguely excited, and he was about to officially set foot on this planet.

"Mars is so cruel... will there be life?" the girl shook her head and asked.

"I don't know, but it's almost impossible. Even if there is, it's a microorganism." Logic replied.

"Is that Olympus taller than Mount Everest?" the girl said curiously.

Logic a black line "That's the Olympics...ah, it's Olympus, and Mount Everest is a child in front of him."

"Then tell me about Mount Olympus." The girl's eyes lit up.

"It's the Olympics, ahhhh...Olympus."

"No matter what he is, tell me."

"Okay." Logic nodded.

"Olympus Mountain is the parasitic volcanic cone of the largest volcano in the solar system. Its slope is gentle and shaped like a huge shield. The bottom diameter of the volcano is 600 kilometers. The bottom area is larger than the British land area. It has an altitude of more than 27 kilometers and an average height of 22 kilometers. It is three times the height of Mount Everest on Earth. The crater diameter reaches 80 kilometers and is about 3 kilometers deep. It is more than enough to accommodate two Londoners. For comparison, the largest volcano on Earth, the Great Tamu Volcano, is located on the Pacific Ocean bottom 1,000 miles east of Japan. It covers an area of ​​120,000 square miles. The circular dome extends more than 650 kilometers, but it is much smaller than the Martian volcano Olympus. The peak is about 2,000 meters below the sea surface and the bottom is about 6.4 kilometers deep."

"It was named Olympus Mountain after taking photos of it from orbit by Sailor 9 in 1972, and it was determined that it was higher than any mountain on Earth."

"So amazing." The girl exclaimed.

"A mountain is actually bigger than that of Britain? Then do you think there is life in the mountain?" asked the girl.

"...How can I know? Then I just apply to go to that mountain to take a look." Logic spread his hands helplessly.

"Really?" The girl's eyes lit up.

"I don't dare to lie to you either."

"Then tell me more about Mars. If you can do this, I'll visit one by one." The girl said excitedly.

"Oh..." Logic sighed helplessly and started speaking.

"There is another canyon on Mars, called Mariner Canyon. It is the largest canyon on Mars and the largest and longest canyon in the solar system. It is located in the eastern part of the Talses Plateau, 4,000 kilometers long, 200 kilometers wide, and 7 kilometers deepest, forming a complex canyon system. It is 10 times longer and 5 times deeper than the American Grand Canyon on Earth. It is formed by the cracking of the crust when the Talses Plateau is formed. It starts from the Noctis maze in the west, passes through a large chaotic terrain in the east and then turns north into the Chris Plain. There are several canyons "flowing in", such as the Kasse Canyon and the God of War Canyon. At the ends of each canyon, there are often teardrop-shaped "islands" - prominent flat-topped highlands, which are the terrain eroded by water flow."

"There are some strange caves on Mars, which were discovered by Mars exploration orbiter and Opportunity respectively. There were clues about water on the surface of Mars and that Mars might have groundwater. Recently, American scientists discovered seven strange caves on Mars with the help of the "Odyssey" probe.

These seven caves are distributed on the sides of the Alcian volcano on Mars. The width of the cave entrance is between 100 meters and 252 meters. Since the hole cannot be basically observed at the bottom of the cave, scientists can only estimate that the caves are at least 80 meters to 130 meters deep.

The discovery of these caves is of great significance. First, if there were primitive forms of life on Mars, these may be the only natural structures on Mars that can provide protection for life. Second, if the conditions are appropriate, these caves may serve as residence points for humans to land on Mars in the future.

Every summer, methane will pop up in these caves, which will increase the possibility of life in the caves."

"Life!" The girl suddenly became interested.

"You can not go to other places, you must go to this place!" the girl said firmly.

"I want to go too, and I will apply for it with all my might." Logic said.
Chapter completed!
