Chapter 205, Exploring Mars ([-])

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

"Mars is so desolate. You can clearly see the surface of Mars from space. Sand dunes and gravel are everywhere, and the world is full of red."

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, especially with the help of a telescope.

"These are the colors formed by iron oxide. The sandstorm on Mars is really powerful. Look here, the wind speed has reached an unprecedented level of 21. This is impossible on earth. Flying sand, rocks, and dust are all It's not enough to describe."

Pointing to an area in the southern hemisphere of Mars, Liu Yi 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.

"Great storms on Mars mainly occur in the southern hemisphere of Mars. The current time is almost considered to be the summer solstice in the southern hemisphere of Mars. It is considered 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 hurricanes, the surface of Mars is full of sand, once a super hurricane is formed, it can even sweep the entire Mars, it seems that we should 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, and carefully analyzed the reasons for the formation of this big storm. One is that the temperature difference on Mars is too large, and the other is that there are a lot of sand and tiny particles on the surface of Mars, so it is easy to It formed this kind of spectacle that only exists on Mars.

"Release the detection satellite and establish a global positioning communication system."

"Release the unmanned probe."

"Release the unmanned Mars lander."

"..."

After arriving on Mars, all kinds of probes and exploration satellites don’t need to be distributed like money. In the past, launching a satellite was considered a big event, and it was broadcast on the news. But now, countless private space technology companies in China They all have many satellites of their own, not to mention Fuyun Group.

The large number of applications and popularization of aerospace aircraft has 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.

"Drip!"

Various probes soon began to send back various information to the "Ocean" spacecraft, established a global positioning system and communication system on the Mars side, and began to send information to the Earth side, which will The detailed information here on Mars is sent back to Earth, which is convenient for scientists on Earth to conduct in-depth research on Mars.

"This Phobos and Deimos are probably the smallest satellites in the entire solar system. The mass of the two satellites is too small, and they are not even spherical in shape. Phobos looks like a potato, with an escape velocity of 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 mass of these two satellites, the mass of Phobos is only 1.38×10^14 kilograms, and the mass of Deimos is only 1.8×10^13 kilograms, both of which are very small. You must know that the mass of the moon is 7.349× 10^22 kilograms is not a weight class at all, and Phobos and Deimos can only be regarded as relatively large asteroids at best."

The cosmic and astronomical scientists who followed this time were still Dong Zhifei and Tang Boyuan, and they easily and accurately calculated the masses of the two Mars satellites.

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

"I estimate that Phobos and Deimos should be asteroids captured by the gravity of Mars. Their mass is too small. If they are placed on the earth's side, they will not even cause any tides."

Looking at the data of the two satellites, Tang Boyuan speculated on the origin of the two satellites.

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

Dong Zhifei also nodded. It is the easiest and most convenient way 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 even less than 1 kilometers. The distance between the two is only about 2.3 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 the mass is very large like the moon, the corresponding distance will continue to increase.

In the outer space of Mars, on the huge "Ocean" spacecraft, a small unmanned spacecraft slowly flew away, constantly changing orbits in space, and soon went straight to Phobos and go.

At this time, Mars-[-] is still moving around Mars, and it has to fly around Mars for three days every day. The unmanned spacecraft has adjusted to the orbit of Phobos at this time, and the speed is faster than Phobos. Therefore, the two The distance between them is gradually approaching.

The distance between the unmanned spacecraft and Phobos is very close, and it is slightly affected by the gravity of Phobos, but the gravity of Phobos is too weak. For the unmanned spacecraft equipped with plasma engines Nothing much.

The unmanned spacecraft slowly approached Phobos, as if approaching a space port in space. The robotic arms on the spacecraft slowly stretched out, and began to collect samples on Phobos, so that scientists By analyzing these samples, we can know the approximate time period when Phobos was formed, and by analyzing the source and formation of these substances, we can roughly know the history of Phobos, the reason 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 satellites like Phobos and asteroids in the asteroid belt, etc. It may be produced by the early evolution of the solar system, carrying some early information of the solar system.

Large planets such as Earth, Mars, Venus, etc., have long been difficult to find because of their huge mass, coupled with their own activities, etc. On the contrary, these asteroids and so on are very likely to carry early information.

After collecting the samples, the unmanned detection spacecraft slowly left Phobos, and began to change its orbit in space, and began to approach Deimos. In the same way, it successfully obtained the samples on Deimos, and then began to carry The sample returned to the "Ocean" spacecraft.

In the space of Mars, the "Ocean" spacecraft is extremely busy. Scientists have a clear division of labor, each controlling the unmanned probe, unmanned detection spacecraft, unmanned landing spacecraft, etc. to explore the entire Mars.

PS: I would like to wish the book lovers an early year, and wish them all the best and good health in the new year!
