Chapter 1793: Deimos

Chapter 1793 Deimos

At this time, Zhao Zhongyao looked at the bottom of the crater in the distance and said, 'I think we can fly directly there. '

After hearing what his father said, Feifei said in puzzlement, 'How can we fly to the bottom of this crater? It's almost impossible. '

Zhao Zhongyao said, ‘This Phobos has very little gravity, only one-thousandth of that of the earth. As long as we jump, we can fly to the bottom of this crater. '

‘Then what if we fly directly into space! It doesn't mean that the gravitational force of Phobos is very small, whether we will be launched into space directly like a rocket when we jump up. ’ Feifei thought, if the gravitational force of Phobos is very small. Then they might fly directly into space like a rocket.

After hearing Feifei's words, Zhao Zhongyao said again,'This is unlikely, we can't launch into space like a rocket. After all, we alone are too small compared to this planet. Although this one Phobos doesn't have much mass. But compared to a person, it is still very large.

We don't have to worry about flying into space. I don't see that possibility at all. It doesn't matter if we fly into space! Our spaceship can catch up to us very quickly. We don't have to worry about anything. As long as your mother and sister are in the spaceship, we can just jump.

Even if we really fly into space, just let your mother and sister pick us up in a spaceship. You don't have to worry about us flying into space. '

When Zhao Zhongyao said this, Feifei felt that it made sense. If this is the case, there is nothing to worry about.

So, Feifei looked at Dad again and said, 'Dad, let's start flying up! '

After speaking, Feifei wanted to jump up. But as soon as he jumped, Zhao Zhongyao caught him. Then I looked at him and said, 'Don't jump in a hurry, let's dance together. I'll take your hand, it's not that much safer. '

After finishing speaking, Zhao Zhongyao grabbed his son's hand. Then Zhao Zhongyao called one, two, three. They jumped up together.

This jump up is really incredible. The two of them really flew into space like launching a rocket.

Feifei was a little scared now, he looked at his father and said, 'No, we are going to fly into space. '

Zhao Zhongyao smiled and said,'It doesn't matter! We are just flying. We can't fly very far, and soon we'll be coming down again. '

Sure enough, after Zhao Zhongyao said this, Feifei felt that his ascent slowed down. At this time, they had already flown to an altitude of several hundred meters. But this time? Their ascent speed slowed down.

After they climbed another hundred meters? They stopped rising. It seems that they have been pulled by this satellite? Then they will not continue to rise.

'Dad, we're not going any further up. ’ Feifei looked at his father and said.

'Of course? We can't keep going up? We'll be going down soon. Zhao Zhongyao said so.

Sure enough, after Zhao Zhongyao said this, they began to descend slowly. Soon, they dropped more than a hundred meters. After that? They descended another few hundred meters. Then it slowly fell to the bottom of this huge crater.

Feifei saw that he and his dad had landed safely? He felt relieved.

'Dad, we're all right, we landed safely. ’ Feifei looked at his father with a happy face and said.

'Yes, we landed safely. 'Zhao Zhongyao also looked happy.

The two have now landed safely on the bottom of this huge crater. This huge crater is part of the original larger crater. After the huge crater was formed, it was formed by the impact of an asteroid.

Zhao Zhongyao and Feifei conducted an investigation in this crater. What do they feel? At the bottom of this one crater, there's something very special. These things? They are things like ice.

Feifei looked at these things and asked Dad? 'Dad, what is this thing? Why does it look like ice cubes! '

Zhao Zhongyao looked at these white substances and said, "These things? They should be the wreckage of some comets." This one crater was probably formed by the impact of a small comet. When this comet hit the original huge crater, this smaller crater was formed again. '

'oh! It turned out to be like this. Does that mean that there is water in the ground of Phobos? Since a comet has hit the surface of this Phobos, will there be a lot of fresh water under this Phobos? ’ Feifei felt that since a comet hit this Phobos. So should there be fresh water in the ground of Phobos?

After hearing Feifei's words, Zhao Zhongyao said,'This is also possible. After all, a comet is a moving reservoir. As long as it is a planet hit by a comet, there may be water resources on it. Billions of years ago, our Earth was hit by a huge comet to form what it is today. '

Feifei nodded after hearing what her father said, but didn't say anything more.

Next, Zhao Zhongyao and Feifei inspected this crater for a while. But nothing special was found.

Feifei saw that there was nothing more to investigate in this crater, so he said, ‘Then we have almost inspected this satellite now. I

Should we go to another satellite to have a look. '

After hearing Feifei's words, Zhao Zhongyao said, 'Okay, then let's go to another satellite of Mars to have a look! '

After finishing speaking, Zhao Zhongyao took Feifei and jumped again, and flew out from the bottom of this huge crater again, and flew directly to the vicinity of their spaceship.

After flying near the spaceship, Zhao Zhongyao and Feifei boarded their spaceship again.

Just now, the actions of Zhao Zhongyao and Feifei also surprised Qu Yuqian and Tiantian. After the two of them went in. Qu Yuqian and Tiantian also asked Zhao Zhongyao and Feifei. How did the two of them think of flying on this Phobos in this way.

Feifei smiled and said, 'Of course our father thought of this. What a smart man our dad is, of course he can think of such a method. '

After listening to Feifei's words every day, he looked at his father and said, 'Dad, you are really smart, you can think of such a way to fly on Phobos. '

After hearing what Tiantian said, Zhao Zhongyao smiled and said, Haha, what's the matter with this! As long as you use your brain a little, you can think of it. '

Feifei was anxious to go to Deimos to have a look. So, I looked at my dad and said, 'Dad, let's go to Deimos quickly! I want to see what Deimos looks like. '

‘Well then, let’s hurry to Deimos! Zhao Zhongyao said this again after hearing what his son said.

So, Zhao Zhongyao drove the spaceship to Deimos again. The speed of the spacecraft is very fast, and it only took a while to fly to Deimos again.

Deimos is the smallest satellite of Mars, with an average radius of 6./s (20 km/h). It is the smaller and outer known satellite of Mars. The other is Phobos. Deimos is at a distance of 23,460 kilometers (14,580 miles) from Mars and orbits Mars every 30.3 hours at an orbital speed of 1.35 kilometers per second. Deimos' orbit is nearly circular and close to the equatorial plane of Mars.

Deimos, the outer satellite of Mars, may be an asteroid perturbed by Jupiter into an orbit that can be captured by Mars, but this hypothesis is still controversial and opposed. The orbits of Phobos and Deimos are almost Circular and close to the equatorial plane of Mars, Buhui said that a mechanism is needed to turn the orbit that was originally a high oblate heart rate into a circular shape, and adjust its inclination to enter the equatorial plane. Most likely it is atmospheric drag and tidal force, however It's not clear how long it would take for Deimos to undergo such changes.

Looking at Deimos from Mars, its apparent diameter will not exceed 2.5 arc minutes (60 angles are divided into 1 degree), which is only one-twelfth of the moon seen from the earth, so it looks like a star point to the naked eye. When it is at its brightest ("full moon"), it is about as bright as Venus as seen from Earth; at its upper and lower chords it is about as bright as Vega. Viewed with a small telescope, observers on Mars can see Deimos It takes 1.2648 days (the synodic cycle of Deimos) to complete a phase change.

Unlike Phobos, which orbits at a very high speed, it actually rises in the west and sinks in the east; Deimos rises in the east and sinks in the west, and Deimos is gradually moving away from Mars. But Deimos and the sun have a rendezvous period of about 30.4 hours, which exceeds Mars' 24.7-hour Martian solar day ("sol"). This small time difference makes it 2.7 days for observers on Mars' equator to observe it. Once, because Deimos's orbit is relatively close to Mars and its inclination to the equatorial plane is small, Deimos cannot be seen in the polar regions at latitudes higher than 82.7° on Mars.

Mars can still regularly see Deimos passing in front of the sun regularly. But it is too small to cause a total solar eclipse, just a small black spot across the surface of the sun. Its angular diameter is only 2.5 times the apparent diameter of Venus when seen from Earth as it transits the sun. On March 4, 2004, the Mars rover Opportunity captured images of a transit of Deimos; on March 13, 2004, Spirit rover also captured another transit.

Zhao Zhongyao is now driving the spaceship, and will soon fly to Deimos. Deimos is more than 20,000 kilometers away from Mars. It is a very small satellite. Just over six kilometers in diameter.

For Zhao Zhongyao, such a small satellite feels of no value for investigation. When he flew over this small satellite, he looked at Feifei and said, "This is Deimos, don't you think it's worth investigating, we just take a look inside the spacecraft." It's just a big rock in space. '

After hearing what his father said, Feifei looked at the big rock outside the spaceship. He also feels that this Deimos is nothing to look at.

So, after looking at this Deimos satellite for a while, Feifei looked at Dad again and said, 'Dad, let's go to Mars! This Deimos is also nothing to see. '

After hearing Feifei's words, Zhao Zhongyao said, 'Okay, then let's go to Mars. Mars is our travel destination this time. '

After finishing speaking, Zhao Zhongyao drove the spaceship to Mars again. From here, it is more than 20,000 kilometers away from Mars. This is nothing to a flying saucer spacecraft. They can fly to Mars soon.

In this way, Zhao Zhongyao drove the spacecraft and soon flew over Mars. Mars is a big rusty rock. Mars is covered entirely with a layer of hematite sand.

If you just look at Mars from a high altitude, there is nothing to see. On this Mars, since there are no green mountains and green waters, there is no blue sea and blue sky. There are patches of desert everywhere.

At this moment, Feifei looked at Dad and said, 'Dad, we have already flown above Mars. then we should now

Where to go to see it! Is there any place on Mars worthy of our travel and exploration? '

After hearing Feifei's words, Zhao Zhongyao said,'There are three places on Mars that are most worth seeing. One is the highest mountain on Mars - Olympus Mons. There is also the largest canyon on Mars-the Grand Canyon of the Mariners. In addition, there are ice caps at the poles of Mars. These three places are the places with the most tourist value on Mars. '

'Dad, then we should go to that place first. ’ Feifei looked at his father and said.

Zhao Zhongyao thought for a while and said, 'Then let's go to the poles of Mars to see it first! Heard about the fresh water there. Maybe some signs of life will be found. '

After listening to what his father said, Feifei said, 'Okay, let's go to the poles of Mars first. Let's see if there is life at the poles of Mars. '

‘Okay, then let’s go to the North Pole of Mars first! 'Zhao Zhongyao looked at Feifei again and said.

‘Okay, let’s go to the North Pole of Mars first! I hope that in the north pole of Mars, we can find some signs of life. ’ Said Feifei.

So, Zhao Zhongyao drove the spacecraft to the North Pole of Mars. Soon, they flew to the North Pole of Mars.

The north pole of Mars is very cold. Unlike other places on Mars. The temperature elsewhere on Mars is still very suitable for the existence of life. After all, Mars is the planet in the solar system with the most suitable surface temperature for life besides the Earth.

The next planet that we humans can migrate to is Mars, which is more suitable for human habitation. If humans want to colonize interstellar space next, the first consideration should be Mars.
