Universe dominance

The speed of the "Ocean" spacecraft has been reduced to only a few kilometers per second. It was successfully captured by the gravity of Mars and began to orbit Mars.

"Mars is so desolate. You can clearly see the surface of Mars from space. It's full of sand dunes and gravel, and it's a red world as far as the eye can see."

Liu Shiying looked at Mars outside the window. Because the earth on Mars is very thin, the surface of Mars can be seen very clearly even with the naked eye in space, and it can be seen clearly with the help of a telescope.

"These are the colors formed by iron oxide. The sandstorms on Mars are really powerful. Look here, the wind speed has reached an unprecedented level of 21. This is impossible to happen on earth. The flying sand, rocks and dust are all... Not enough to describe it.”

Liu Yi pointed to an area in the southern hemisphere of Mars and said in surprise that the big storm on Mars can be seen with the naked eye, which shows how terrible the big storm on Mars is.

"Mars major storms mainly occur in the southern hemisphere of Mars. The current time is almost the summer solstice in the southern hemisphere of Mars, which is the perihelion of Mars. The air is extremely hot and unstable. Coupled with the huge temperature difference on Mars, it is very easy to form. Super hurricane, the surface of Mars is full of sand, and once a super hurricane forms, it can even sweep across the entire Mars. It seems that we need to be more careful and pay attention when conducting Mars exploration. "

Li Fu on the side was also admiring the big storm on Mars at this time. He carefully analyzed the reasons for the formation of this big storm. One is that the temperature difference on Mars is too different, and the other is that there are a lot of sand and tiny particles on the surface of Mars, so it is easy to This forms a spectacle that is only seen on Mars.

"Release detection satellites and establish a global positioning communication system."

"Release the unmanned probe."

"Release the unmanned Mars lander."

"..."

After arriving at Mars, various detectors and detection satellites were thrown out for free. In the past, launching a satellite was considered a big event and would be reported on the news. But now, countless private space technology companies in China have They all have many satellites of their own, not to mention Fuyun Group.

The extensive application and popularization of aerospace aircraft has reduced the cost of construction and launch of satellites, spacecraft, etc. to an almost negligible level. Of course, this is also for a super behemoth like Fuyun Group.

"Didi!"

Various detectors soon began to transmit various information back to the "Ocean" spacecraft, established the global positioning system and communication system on Mars, and began to send information to the Earth, bringing Detailed information on Mars is transmitted back to Earth, allowing scientists on Earth to conduct in-depth research on Mars.

"Phobos and Deimos are probably the smallest satellites in the entire solar system. The masses of the two satellites are too small, and their shapes are not even spherical. Phobos looks like a potato, and its escape velocity is only 17.2 m/s, Deimos is even smaller, with an average radius of only 6.2 kilometers and an escape velocity of only 5.6m/s.”

"The masses of these two satellites, Phobos has a mass of only 1.38×10^14 kilograms, and Deimos has a mass of only 1.8×10^13 kilograms. They are both very small. You must know that the moon has a mass of 7.349× 10^22 kilograms is not a weight class at all, and Phobos and Deimos can only be regarded as larger asteroids at best. "

This time, the scientists majoring in cosmic astronomy who followed were still Dong Zhifei and Tang Boyuan. The two easily and accurately calculated the masses of the two satellites of Mars.

The detection satellite has calculated the shape, volume, orbit, speed and other detailed information of the two satellites. At such a close distance, the mystery of the two satellites of Mars has finally been revealed. In fact, there is nothing surprising at all. Not a moon at all, just a larger asteroid.

"I estimate that Phobos and Deimos are asteroids captured by the gravity of Mars. Their masses are so small that if they were placed on the Earth, they would not even be enough to cause any tides."

Tang Boyuan looked at the data of the two satellites and speculated on their origins.

"Send some detectors up there to have a look, collect some samples and come back for analysis."

Dong Zhifei also nodded. It is easiest and most convenient to study the satellites of Mars in space, because the two satellites of Mars are very close to Mars. The average distance of Phobos is less than 10,000 kilometers. The distance between the two is only about 23,000 kilometers, so they are very close.

Of course, this is also because the masses of the two are very small, so the distance can be so close. If it is like the moon, the mass is very huge, and the corresponding distance will continue to increase.

In the outer space of Mars, atop the huge Ocean spacecraft, a small unmanned exploration spacecraft slowly flew away, constantly changing its orbit in space, and soon headed straight for Phobos. And go.

At this time, Mars 1 is still in constant motion around Mars, flying around Mars for three days every day. The unmanned exploration spacecraft has now adjusted to the orbit of Phobos, and its speed is faster than that of Phobos, so the two The distance between them is getting closer and closer.

The unmanned exploration spacecraft is already very close to Phobos and is slightly affected by Phobos' gravity. However, Phobos' gravity is too weak. For an unmanned exploration spacecraft equipped with a plasma engine, No big impact.

The unmanned exploration spacecraft slowly approached Phobos, as if approaching a space port in space. The mechanical arms on the spacecraft slowly stretched out and began to collect samples from Phobos so that scientists could By analyzing these samples, we can know the approximate time period when Phobos was formed. By analyzing the source and formation of these materials, we can roughly know the history and cause of formation of Phobos, and when it became a satellite of Mars.

If you are lucky, you can even learn some information about the origin of the solar system from Phobos, because according to scientists' speculation, small satellites like Phobos and asteroids in the asteroid belt are all It may be produced by the early evolution of the solar system and carry some information about the early solar system.

Large planets such as the Earth, Mars, Venus, etc., have long been difficult to detect because of their large mass, coupled with their own activities, etc., and there is not much to study the formation of the solar system. effect, on the contrary, these asteroids, etc. are very likely to carry early information.

After collecting the samples, the unmanned exploration spacecraft slowly left Phobos, began to change its orbit in space, and began to approach Deimos. Following the same pattern, it successfully obtained the samples from Deimos, and then began to carry them. The sample is returned to the Oceania spacecraft.

In the space of Mars, the "Ocean" spacecraft is extremely busy. The scientists have a clear division of labor. They each operate unmanned detectors, unmanned exploration spacecraft, unmanned landing spacecraft, etc. to explore the entire Mars.
