Chapter 1792 Comes to Mars’ Satellite Phobos

At this time, Feifei looked at Zhao Zhongyao and said, 'Dad, I'm ready to land on Mars, and I must have a good trip on Mars this time. Mars is one of my favorite planets. '

'Okay, then let's start flying to Mars! After Zhao Zhongyao finished speaking, he drove the spaceship to Mars again.

Only when flying hundreds of thousands of kilometers away from Mars, Feifei thought that Mars still has two small natural satellites. He thought, since he wanted to travel and explore Mars, he might as well visit the two small moons of Mars first. After all, these two small satellites are not well understood by ordinary people.

As far as Feifei is concerned, although he has learned some knowledge about Mars, he doesn't know much about what the two small moons of Mars look like. He wanted to learn more about the two small moons.

Thinking of this, Feifei looked at Zhao Zhongyao and said, 'Dad, why don't we go to the two small satellites of Mars to have a look first! Are these two small satellites also very special, why don't we go on a trip to these two small satellites first. '

After hearing Feifei's words, Zhao Zhongyao also smiled and said,'Okay, then let's travel to the two small satellites of Mars first. '

After hearing what Dad said, Feifei said again, 'Dad, then which satellite should we travel to first? '

Feifei knows that Mars has two moons, Phobos and Deimos. Both moons are very special, very small planets in the solar system.

After hearing Feifei's words, Zhao Zhongyao said, 'Of course I went to travel on Phobos first. Because this is a very special small satellite. '

‘Okay, then let’s go to Phobos first! ’ After listening to what Dad said, Feifei also agreed with Dad.

So, Zhao Zhongyao drove the spaceship to Phobos. The spaceship is fast. In just a short while, they flew near Phobos.

Now the spacecraft is tens of kilometers away from Phobos. From this place, the situation of the entire Phobos can already be clearly seen.

‘Dad, this is really a very special little satellite! Then your dad, do you know this small satellite very well? Can you tell me more about the knowledge about this small satellite. ’ Feifei looked at Dad again and said.

'I know a lot about this small satellite, so let me tell you some more about this small satellite! '

Next, Zhao Zhongyao talked about some knowledge about this small satellite.

Phobos is a small, irregularly shaped body. Phobos is one of the faintest objects in the solar system. It moves around Mars, orbiting Mars three times a day, and the average distance from Mars is about 9378 kilometers.

Phobos is potato-shaped and circles Mars three times a day, with an average distance of 9,378 kilometers from Mars. It is the larger and closer of Mars' two moons. The distance between Phobos and Mars is also the shortest among all satellites in the solar system and their main star, only 6000 kilometers from the surface of Mars. It is also one of the smallest moons in the solar system,

Phobos is a small, irregularly shaped body. Moving around Mars, the orbit is about 9400km from the center of Mars, which is 6000km from the surface of Mars. Phobos is closer to its parent star than any moon of any other known planet. Phobos is one of the celestial bodies with the lowest reflectivity in the solar system. There is a huge impact crater on Phobos? It is called Stickney impact crater. Due to its close orbit to Mars, Phobos rotates faster than Mars does. So from the surface of Mars, Phobos rises in the west, crosses the sky and sets in the east in 4 hours and 15 minutes or less. Due to the short orbital period and the effect of tidal force, the orbital radius of Phobos is gradually decreasing? Eventually it will hit the surface of Mars? Or break up to form a Martian ring.

Is Phobos an irregularly shaped celestial body? It is roughly 27 kilometers long, 22 kilometers wide, and 18 kilometers high. It orbits Mars every 0.319 days at a distance of 9,235.69,518.8 kilometers from Mars? Is this faster than Mars' rotation rate? So, if humans reach Mars, they can also see the Martian 'moon' rising in the west and setting in the east? Phobos and Deimos is mostly considered to be a captured asteroid? There are also some people who believe that they originated outside the solar system? Not from the asteroid belt.

In December 1971, the American Mariner 9 Mars probe took the first pictures of Phobos and Deimos. The outline size of Phobos is 26.6 km x 22.2 km x 18.6 km? It is shaped a bit like a potato. It orbits at an average distance of about 6,000 kilometers from Mars? It takes 7 hours and 39 minutes to make one revolution. Due to its small size and weight, Phobos has a relatively weak gravitational force, only 1/1600 that of Earth. In addition, Phobos' orbit is slowly decaying (down 9 meters every 100 years), and it will crash into Mars in another 40 million years.

Phobos has always been the object of study for scientists? Understanding Phobos can give us a lot of information about the early history of the solar system. Alexander Zakharov, chief scientist of Russia's "Phobos-Soil" program, said: "It may provide us with clues about the formation of Earth's satellites and other planetary satellites? role." Phobos' longest axis always points toward Mars? Does one side always face Mars? Making it an ideal spot for observing most of the surface of Mars.

At the end of the last century, the former Soviet Union/Russia successively formulated and implemented two plans to use autonomous probes to study Phobos

Unfortunately, due to the failure of the detector and the launch vehicle, it was not successful. The first plan began in the late 1970s? Due to technical and financial considerations, it was planned to manufacture two spacecraft, one hovering at an altitude of 50 meters above Phobos for television photography and scientific experiments; Execute the Phobos sample return mission. The two probes were launched in 1988, so they are called the "Phobos-88" project. In addition to Phobos, the research targets of the mission also include Mars, the sun and space.

Zhao Zhongyao looked at Feifei, and then told some knowledge about Phobos. After hearing this, Feifei became a little curious about this small satellite.

‘Dad, can our spaceship land on this small satellite? I thought of going to have a look on this small satellite. Feifei looked at Zhao Zhongyao and said.

After hearing Feifei's words, Zhao Zhongyao said, "Okay, what's the difficulty? Our spaceship can land on any planet it wants to land on." We can land on any planet or satellite in the solar system. '

'Well, let's go to this small satellite first to have a look. I heard that there is abundant groundwater on this small satellite! Can we go up there and explore it? Feifei looked at Zhao Zhongyao again and said.

‘That’s right, I also heard that there is abundant groundwater on this small satellite, why don’t we go to this small satellite to have a look first. '

After Zhao Zhongyao finished speaking, he drove the spaceship to this small satellite again. It's a small satellite that's a bit like a big potato. Just at one end of this small satellite, there is a huge impact crater. It may be that hundreds of millions of years ago, when an asteroid flew over this place, it collided with this small satellite.

Zhao Zhongyao is now flying the spacecraft to this mysterious small satellite-Phobos. Their spacecraft quickly flew over the small satellite.

Zhao Zhongyao directly drove the spacecraft to the end of this small satellite. That is, the sky above the impact crater.

Zhao Zhongyao decided to land the spacecraft into this impact crater. Then, he and Feifei can get out of the spaceship and go on an expedition to the surface of this small satellite.

Feifei also wants to explore the surface of this small satellite. He saw Dad drive the spaceship over the crater. I looked at my dad and said, 'Dad, let's land under this crater! '

'Well, we're going to land on the bottom of this one crater. This is a very strange impact crater, let's go inside and study it. '

After Zhao Zhongyao finished speaking, he drove the spaceship slowly towards the bottom of this impact crater. Soon, their spacecraft landed on the bottom of this huge impact crater.

Seen from the air, this impact crater is not particularly large. But when they landed the spacecraft on the bottom of this impact crater, they realized that it was a very huge impact crater.

This impact crater is Stickney Crater. There is also a smaller crater, about 2 kilometers (1.2 miles) in diameter, within Stinek, created by a later impact. Grooves and chain pits appear to radiate from Stickney.

These impacts, which led to the formation of Stickney Crater, all but destroyed the theory of Phobos. However, evidence from the Mars Express orbiter suggests that these are related to Stickney Crater and may have been affected by material ejected from Mars.

What is worth noting about this crater is that some material on the inside fell into the crater to form soil and rock pouring, resulting in obvious linear textures. Stickney Crater may be large enough to be seen with the naked eye from the surface of Mars. It is located in the center of the western edge of Phobos' frontal face facing Mars.

Zhao Zhongyao parked the spacecraft at the bottom of this huge impact crater. Then, he took Feifei out of the spaceship. Of course, the two of them also got out of the spacesuit after putting on their spacesuits. This is a very strange cold world. They have to wear spacesuits to come outside the spacecraft.

Just now, Tiantian had to make a noise to come outside the spaceship! But Zhao Zhongyao told her. There's nothing fancy about this Phobos either. He and Feifei just went outside for a while and will come back. Their goal is Mars, not this small satellite.

After listening to my father's words every day, I stopped clamoring to go out.

Zhao Zhongyao and Feifei got out of the spacecraft together, and then set foot on the hard rocky surface of Phobos.

Due to the small size and mass of Phobos. The gravitational force on it is also very small. About one-thousandth the size of the earth.

When Zhao Zhongyao and Feifei came out of the spaceship. Zhao Zhongyao looked at Feifei and said,'We should be more careful when we walk on this small satellite. This small satellite has very little gravity. We can't jump up. If we jump up hard, it is possible to fly into space. Of course, it is very possible to 'fall' directly to Mars. '

Because this small satellite is very close to its parent star, which is Mars. The distance between Phobos and the surface of Mars may be only more than 6,000 kilometers. This is a very close distance. You know, our earth is 300,000 kilometers away from the moon.

After hearing what his father said, Feifei quickly took his father's hand and said, 'It's so scary! Then we must hold hands. Otherwise, we'd both be flying into space. '

Zhao Zhongyao and Feifei walked forward holding hands together. After walking a certain distance, they saw another huge crater in front of them.

Feifei looked at the crater that appeared again, looked at Zhao Zhongyao and said, "Dad, is it strange that there is a huge crater in this huge crater?"

Meteor craters, this is really amazing! '

After hearing Feifei's words, Zhao Zhongyao smiled and said,'Haha, what's so amazing about this. This smaller crater was formed by an impact in this large crater after the formation of this large crater. '

‘Dad, can we go to this smaller crater and have a look! I heard that there are still a lot of water resources on this Phobos! ’ Feifei looked at Dad again and said.

After hearing Feifei's words, Zhao Zhongyao said,'Yes, according to data records, there are a lot of fresh water resources under the surface of this small Martian satellite. This is a very rare thing. '

'Then can we go to this smaller crater and have a look. Let's see if there is water in it. ’ Feifei looked at Dad again and said.

'Okay, since we have come to this place, let's see if there is any water resource in this smaller crater. Zhao Zhongyao said so.

‘Dad, how can we get to this smaller crater! Should we take a spaceship to this smaller crater again? ’ Feifei looked at Dad again and said.

Zhao Zhongyao is now standing on the edge of this huge crater and said, ‘Actually, we can also get to the bottom of this crater in a more fun way. '

After hearing what Dad said, Feifei said in puzzlement, 'Dad, then what method should we use! We didn't take a small planetary vehicle or other means of transportation. How can we quickly get to the bottom of this crater. '

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