Chapter 1605: Phobos

The first thousand seven hundred and ninety-three chapters Phobos
At this moment, Zhao Zhongyao looked at the bottom of the crater in the distance and said, ‘I see, we can fly over. ’
After hearing what his father said, Feifei said in a puzzled manner, ‘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’s not that Phobos’ gravitational force is very small. When we jump up, we will launch directly into space like a rocket. Feifei thought, if the gravity of this Phobos is very small. Then they might fly directly into space like a rocket.
After hearing Feifei’s words, Zhao Zhongyao said, ‘This is unlikely. We cannot launch into space like a rocket. After all, we are really too small for this planet. Although the quality of this Phobos is not great. But compared to a person, it is still very big.
We don’t have to worry about flying into space. I don't think this is possible at all. It doesn’t matter if we fly into space! Our spacecraft can also catch up to us soon. 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, let your mother and sister drive the spaceship to pick us up. You don't need to worry that we will fly into space. ’
When Zhao Zhongyao said so, Feifei felt very reasonable. Since this is the case, there is no need to worry about it.
So Feifei looked at Dad again and said, ‘Dad, then let’s start flying upwards! ’
After speaking, Feifei wanted to jump up. But as soon as he jumped, Zhao Zhongyao caught it. Then he looked at him and said, ‘don’t jump in a hurry, let’s dance together. I'll grab your hand, it's not much safer. ’
After speaking, Zhao Zhongyao grabbed his son's hand. Then Zhao Zhongyao called one, two, three. They jumped together.
This jump is really incredible. The two of them really flew directly into space like they were launching rockets.
Feifei was a little scared now. He looked at his father and said, ‘No, we’re going to fly into space. ’
Zhao Zhongyao smiled and said, ‘It doesn’t matter! We just started flying. We can't fly far, and soon, we will descend again. ’
Sure enough, after Zhao Zhongyao said this, Feifei felt his ascent slowed down. At this time, they had already flown into an altitude of several hundred meters. But at this time, their ascent speed slowed down.
After they had risen more than a hundred meters, they began to no longer rise. It seems that they have already received the traction of this satellite, and then no longer continue to rise.
‘Dad, we don’t go up anymore. Feifei looked at his father and said.
‘Of course, we cannot keep going up, we will go down soon. Said Zhao Zhongyao.
Sure enough, after Zhao Zhongyao said this sentence, they began to slowly decline. Soon, they dropped more than a hundred meters. After that, they dropped a few hundred meters. Then it slowly fell to the bottom of this huge crater.
Feifei was relieved to see him and his father land safely.
‘Dad, we are fine, we landed safely. Feifei looked at his father with a happy expression and said.
‘Yes, we landed safely. Zhao Zhongyao also looked happy.
The two landed safely to the bottom of this huge crater. This huge crater is part of the original larger crater. It was formed after the huge crater was formed and then hit by an asteroid.
Zhao Zhongyao and Feifei conducted an inspection in this crater. They felt that there was something very special at the bottom of this crater. These things are things like ice.
Feifei looked at these things and asked Dad, ‘Dad, what is this, why does it look like ice cubes! ’
Zhao Zhongyao looked at the white matter and said, ‘These things should be the remains of some comets. This crater may have been formed by a small comet impact. When the comet hit the original huge crater, it formed this smaller crater. ’
'Oh! It turned out to be so. Does that mean that Phobos also has water underground. Now that a comet hits the surface of this Phobos, will there be a lot of fresh water under this Phobos? Feifei felt that since a comet had hit this Phobos. So should there be fresh water in Phobos underground?
Zhao Zhongyao heard Feifei's words and 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. Our earth was formed billions of years ago because it was hit by a huge comet. ’
Feifei nodded after hearing what his father said, without saying anything.
Next, Zhao Zhongyao and Feifei inspected this crater for a while. But nothing special was found.
Feifei saw that there was nothing to investigate this crater, and then said, ‘then we have almost investigated this satellite now. Should we go to see another satellite? ’
After hearing Feifei’s words, Zhao Zhongyao said, ‘Okay, let’s go and take a look at another moon of Mars! ’
After speaking, Zhao Zhongyao took Feifei to jump again, and flew out from the bottom of this huge crater, and flew directly to the vicinity of their spacecraft.
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 they both 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 dad thought of this. How clever our father is, of course he can think of such a method. ’
After hearing Feifei’s words every day, I looked at my father and said, ‘Dad, you are so smart, you can think of such a way to fly on this Phobos. ’
After hearing what Tiantian said, Zhao Zhongyao smiled and said, ‘haha, what's the matter with this! You can think of it with a little thought. ’
Feifei was anxious to visit Deimos. So I looked at my father and said, ‘Dad, let’s go to Deimos! I want to see what Deimos looks like. ’
‘Okay, let’s go to Deimos! After hearing what his son said, Zhao Zhongyao said again.
So, Zhao Zhongyao flew to Deimos again in his spacecraft. The speed of the spacecraft was very fast, and after a while, it flew to Deimos again.
Phobos is the smallest satellite of Mars, with an average radius of 6.2 kilometers (3.9 miles) and an escape velocity of 5.6ms (20kmh). It is the smaller and outer known satellite of Mars. The other is Phobos. . The distance between Deimos and Mars is 23,460 kilometers (14,580 miles) orbiting Mars in a period of 30.3 hours, with an orbital speed of 1.35 kilometers per second. The orbit of Deimos is approximately 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 both Phobos and Deimos are almost the same It is circular and close to the equatorial plane of Mars. It is said that a mechanism is needed to turn the orbit that was originally a high flat heart rate into a circle, and to adjust its inclination into the equatorial plane. The most likely cause is atmospheric resistance and tidal force. It is not clear how long it will take for Deimos to undergo such a change.
Viewing from Mars to Deimos, its apparent diameter will not exceed 2.5 arc minutes (60 arcs divided into 1 degree), but only one-twelfth of the moon viewed from the earth, so it looks like a star point to the naked eye. When it is at its brightest ("full moon"), its brightness is approximately close to that of Venus seen from the earth; the brightness of the upper and lower strings is similar to that of Vega. Watching 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 revolving at a very high speed, it actually rises from the west to the east; Deimos rises from the east to the west, and Deimos is gradually moving away from Mars. However, the rendezvous period of Deimos and the Sun is about 30.4 hours, which exceeds the Martian solar day ("sol") of 24.7 hours on Mars. This slight time difference makes observers on the Martian equator observe it every 2.7 days. Once, because the orbit of Deimos is relatively close to Mars, and its tilt to the equatorial plane is also very small, it is not visible in the polar regions at latitudes higher than 82.7° on Mars.
Mars can still see Deimos regularly passing in front of the sun. But it is too small to cause a total solar eclipse, only a small black spot that crosses the surface of the sun. Its angular diameter is only 2.5 times the apparent diameter of Venus when Venus is seen transiting from the earth. On March 4, 2004, the Mars rover Opportunity captured the image of the transit of Deimos; on March 13, 2004, the Valor also captured another transit.
Zhao Zhongyao is now driving the spacecraft, and soon flew to Deimos. Deimos is more than 20,000 kilometers from Mars. It is a very small satellite. The diameter is just over six kilometers.
For Zhao Zhongyao, such a small satellite is of little value for investigation. When he flew over this small satellite, he looked at Feifei and said, ‘this is Deimos, is it not worth investigating? We just have to look inside the spacecraft. This is just a big rock in space. ’
Feifei heard what Dad said, and looked at the big rock outside the spaceship. He also felt that this Deimos was nothing good.
So Feifei looked at this Phobos satellite for a while, then looked at his father and said, ‘Dad, let’s go to Mars! This Deimos is nothing good. ’
Zhao Zhongyao heard Feifei’s words and said, ‘Okay, then we will go to Mars. Mars is our destination this time. ’
After that, Zhao Zhongyao flew to Mars again in his spacecraft. From here, the distance to Mars is more than 20,000 kilometers. This is nothing at all for the 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. All on Mars is a layer of hematite sand.
Just looking at Mars from a high altitude, there is nothing to look at. This Mars is here, since there are no green mountains and green waters, there is no blue sea and blue sky. There are huge deserts everywhere.
Feifei looked at his father and said, ‘Dad, we have already flown over Mars. Where shall we go now? Is there any place on Mars that is worth traveling and exploring? ’
After hearing Feifei’s words, Zhao Zhongyao said, ‘On Mars, there are three places worth seeing. One is the highest mountain on Mars-Mount Olympus. There is also the largest canyon on Mars-Mariner's Canyon. In addition, there are ice caps at the poles of Mars. These three places are the most valuable places for tourism on Mars. ’
‘Dad, then we should go and see 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 first! I heard the fresh water there. Maybe, some signs of life will be found. ’
After hearing what my father said, Feifei said, ‘Okay, let’s go to the poles of Mars first. Let's see if there is life on the poles of Mars. ’
‘Okay, 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 we can find some signs of life at the north pole of Mars. Said Feifei.
So, Zhao Zhongyao piloted the spacecraft and flew 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 life. After all, besides the earth, Mars is the most suitable planet in the solar system with surface temperature for life.
The next planet we humans can migrate to is Mars, which is more suitable for human habitation. If humans want to colonize the stars next, then the first consideration should be Mars.
