After more than ten hours of "long" space flight, Yang Peiqi finally landed on Mars. He also became the first earthling to land on Mars.

It's just that no one knows about this qiē.

Mars is one of the eight planets in the solar system and the fourth planet in the solar system from the inside to the outside. It is a terrestrial planet, with a diameter of about 53% of the Earth, and the inclination angle and rotation period of the rotation axis are similar to those of the Earth, and the rotation time of one revolution is about twice that of the Earth.

Mars is known as the god of war in the West, perhaps because of its bright red color, which is why Mars is sometimes referred to as the "Red Planet".

Before the Greeks, the ancient Egyptians worshipped Mars as the god of farming. Later ancient Greeks regarded Mars as the god of war, Ares, while the ancient Romans inherited the mythology of the Greeks and called it "Mars", the god of war.

In Norse mythology, Mars is the god of war, Tyr. The month March also gets its name from Mars.

In ancient China, Mars was also known as the "Luminous Star", which is due to the fact that Mars is red, fluorescent like fire, and its brightness often changes in the five elements to symbolize fire; And in the sky movement, sometimes from west to east, sometimes from east to west, the situation is complicated, confusing, so in ancient China called it "glowing confusion", there is "glowing firelight, away from the chaos of confusion" meaning.

These legends about Mars are all related to its color. Even the origin of the name Mars is related to its color. And in fact, Mars is not a planet made of fire, the real planet made of fire, which is the star, is the sun. Mars is red because its surface is rich in hematite, also known as ferric oxide. This is an orange-red chemical.

Of course, in the memory of modern man. Mars is more of an equation with aliens than it is in countless science fiction novels or TV movies. There will be things like Martians and the like. This is related to the fact that human scientific research has shown that there may be zài life on Mars.

However, Yang Peiqi did not come to Mars to prove whether there are really aliens here, he came here for only one purpose, that is, to explore mineral resources, especially some high-grade materials. If such a substance can be found, it will be of great benefit to repair the wounds of Explorer VIII.

Mars is a small planet, it is about half the diameter of Earth, has a volume of 15%, and a mass of 11%. The surface area is equivalent to the Earth's land area and is much less dense than the other three terrestrial planets (Earth, Venus, and Mercury).

In terms of radius, mass, and surface gravity, Mars is about halfway between the Earth and the Moon that Yang Peiqi has just landed on: Mars is about twice the diameter of the Moon and half the size of the Earth; The mass is about nine times that of the Moon and 1/9 of the Earth, and the surface gravity is about 2.5 times that of the Moon and 2/5 of the Earth.

However, Mars is also a superstar, especially since the planet is rich in iron. The main element of Martian soil is oxygen, which accounts for about 50%, silicon is 15~30%, iron is 15~16%, aluminum is 2~7%, calcium is 3~8% and a small amount of potassium, phosphorus, sulfur, chlorine, tantalum, chromium, magnesium, cobalt, nickel, copper, etc. The amount of iron in the earth is only 5%. Mars contains more than three times as much iron as Earth!

Yang Peiqi, who was flying at a low altitude on Mars in a spacecraft and conducting mineral exploration, saw the fiery red earth, and he knew it. These are soils rich in ferric oxide. It can be said that those are iron ore.

Mars is not big, and the flight speed of the vehicle that Yang Peiqi is riding in is not slow. However, it is necessary to conduct a more comprehensive exploration of this planet. It takes a lot of time.

Because Mars is rich in iron, it is in this exploration process. Yang Peiqi's harvest is also huge. In the past few hours of exploration, he has discovered no less than 10 large iron ore mines with reserves of more than 10 billion tons. Such iron ore, if put on the earth, can definitely make countless mining companies crazy. However, on Mars, such iron ore is nothing. Yang Peiqi even discovered two super large iron ore mines with reserves of more than 100 billion tons.

Judging from the harvest alone, Yang Peiqi's trip to Mars was a success, and in the past few hours, he has gained even more energy points than he gained on the moon. So far, the range he has explored is only about a quarter of Mars.

In other words, if he fully explored Mars, the energy points he would get might even be more than four times that of the Moon!

It's just that Yang Peiqi is not very happy, because he didn't find any substances that exceeded the eighth level, the vast majority of them were ninth-level substances like iron, and there were a small number of eighth-level substances, and there were no seventh-level substances at all, not to mention the sixth-level substances and fifth-level substances above. And these low-level substances are completely useless for the restoration of Explorer 8.

Yang Peiqi, who was a little lost, suddenly said to Explorer Eight: "Eight, there are so many legends about Martians, do you think there is really a relatively advanced civilization on Mars?" ”

"A more advanced civilization?" Explorer Eight was stunned for a moment, "It's completely impossible. Judging from the area we have just explored, there was indeed life on Mars, but it was very primitive life, basically some single-celled prokaryotes, and even some low-level life that did not have a cellular form. These beings are probably similar to the lives on Earth more than three billion years ago. ”

"In other words, is there really life on Mars?" Yang Peiqi asked.

"Yes, to be exact, there was life." Explorer Eight said.

"What do you mean?" Yang Peiqi was stunned.

"Quite simply, those lives are now dead, and all I have detected are fossils." Explorer Eight said very blandly.

"All dead?" Yang Peiqi was stunned again, "Didn't some scientists on Earth say that there are still microorganisms on Mars?" ”

Explorer Eight said in a disdainful tone, "Do you believe those people?" What real evidence do they have that there is still life on Mars? It's just speculation. Mars, like Earth, is home to carbon-based life, which requires oxygen. But is there oxygen on Mars today? ”

"Not necessarily, aren't some life anaerobic and don't need oxygen to survive?" Yang Peiqi shook his head and said.

"It is true that anaerobic life does not need oxygen, and even obligate anaerobic life will die when it encounters oxygen. But this is just a direct need for oxygen. If there is no oxygen at all on a planet, anaerobic life will also die, unless it is other life forms such as silicon-based life, which really do not need oxygen. Explorer Eight said lightly.
