The speed of the Ocean spacecraft has been reduced to only a few kilometers per second, and it has been captured by the gravitational pull of Mars very smoothly and has begun to orbit Mars.

"Mars is so inhospitable that you can clearly see the surface of Mars from space, with sand dunes and gravel all over the place, and a red world all over the eyes."

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

"These are the colors formed by iron oxide, the sandstorm on Mars is really powerful, you look here, the wind speed has reached an unprecedented level of 21, which is impossible on the earth, flying sand and rocks, dust is not enough to describe."

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

"The Martian storm mainly occurs in the southern hemisphere of Mars, and now the time is almost the summer solstice in the southern hemisphere of Mars, which is the perihelion of Mars, the air is particularly hot, very unstable, and the huge temperature difference on Mars, so it is very easy to form a super hurricane, and the surface of Mars is sandy, and a super hurricane can even sweep the entire Mars once it is formed, it seems that we should be more careful and pay attention to it when exploring Mars."

Li Fu on the side was also admiring the big storm on Mars at this time, and 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 is a lot of sand and tiny particles on the surface of Mars, so it is easy to form this kind of spectacle that only exists on Mars.

"Release the probe satellites and establish a global positioning communication system."

"Release the unmanned probe."

"Release the unmanned Mars landing vehicle."

“……”

Arriving on Mars, all kinds of probes and exploration satellites don't need to be thrown out like money, and launching a satellite used to be a big deal and had to be broadcast on the news, but now, countless private space technology companies in China have many of their own satellites, not to mention Fuyun Group.

The large number of applications and popularization of aerospace aircraft have reduced the cost and launch cost of satellites, spacecraft, etc. to an almost negligible level, of course, this is also for a super behemoth like Fuyun Group.

"Didi!"

All kinds of probes soon began to transmit all kinds of information back to the "ocean-going" spacecraft, established a global positioning system and a communication system on the Martian side, and began to send information to the earth, transmitting detailed information from here on Mars back to the earth, so as to facilitate scientists on the earth side to conduct in-depth research on Mars.

"This Phobos and Deimos are probably the smallest moons in the entire solar system, the mass of the two satellites is too small, even the shape is not spherical, Phobos looks like a potato, the escape speed is only 17.2m/s, and the Phobos is even smaller, the average radius is only 6.2 kilometers, and the escape speed is only 5.6m/s."

"The mass of these two satellites, the mass of Phobos is only 1.38×10^14 kilograms, and the mass of Phobos is only 1.8×10^13 kilograms, the mass is very small, you must know that the mass of the moon is 7.349×10^22 kilograms, which is not a weight class at all, and Phobos and Deimos can only be regarded as a relatively large asteroid at most."

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

The exploration satellite has calculated the shape, volume, orbit, speed and other detailed information transmission of the two moons, so close distance, the mystery of the two moons of Mars has finally been revealed, in fact, there is nothing strange at all, it is not the moon at all, just a larger asteroid.

"I guess Phobos and Deimos should be asteroids captured by Mars' gravity, and their masses are so small that if they are placed on Earth's side, they are not even enough to cause any tides."

Tang Boyuan looked at the data of the two satellites and speculated about the source of the two satellites.

"Send some probes up and take a look, take some samples and come back and analyze them."

Dong Zhifei also nodded, studying Mars' satellites in space is the easiest and most aspect, because the two satellites of Mars are very close to Mars, the average distance of Phobos is not even 10,000 kilometers, and the distance of Phobos is only about 23,000 kilometers, which is very close.

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

In the outer space of Mars, on the huge "Ocean" spacecraft, a small unmanned spacecraft slowly flew out, constantly changing orbits in space, and soon headed straight for Phobos.

At this time, Mars is still in constant motion around Mars, flying around Mars for three days every day, and the unmanned spacecraft has been adjusted to the orbit of Phobos at this time, and the speed is faster than Phobos, so the distance between the two is constantly approaching.

The unmanned exploration spacecraft is already very close to Phobos, and it is slightly affected by the gravitational pull of Phobos, but the gravitational pull of Phobos is too weak, and it does not have much impact on the unmanned exploration spacecraft with a plasma engine installed.

The unmanned spacecraft slowly approached Phobos, as if it was close to a space port in space, and the mechanical arms on the spacecraft slowly stretched out and began to collect samples from Phobos, so that scientists could analyze these samples, so that they could know the approximate time period of Phobos' formation, analyze the source and formation of these substances, etc., and then we can roughly know the history of Phobos, the reasons for its formation, and when it became a satellite of Mars.

Even if you are lucky, you can even know some information about the origin of the solar system from Phobos, because according to scientists' speculation, small moons like Phobos and asteroids in the asteroid belt may have been produced by the early evolution of the solar system, carrying some information about the early solar system.

Large planets such as Earth, Mars, Venus, etc., because of their too much mass, coupled with their own activities, etc., carry information and so on have long been difficult to explore, and do not have much effect on the formation of the solar system, but these asteroids and so on are very likely to carry early information.

After collecting the samples, the unmanned spacecraft slowly left Phobos, and began to change its orbit in space, and began to approach Phobos.

In the space of Mars, the "Ocean" spacecraft is extremely busy, and scientists have a clear division of labor, each controlling unmanned probes, unmanned exploration spacecraft, unmanned landing spacecraft and so on to explore the entire Mars.

PS: I wish you all the best and a healthy family in the new year!
