The volcano that Erdan and Alice saw had already been discovered by the Mars probe launched by our Earth, and it had a very loud name, Olympus Volcano. That's right, it's Mount Olympus, which is embarrassed to have the same name as a mountain in Greece.

Olympus, Volcano is not only the largest volcano on Mars, but also the largest volcano that has been discovered among the nine planets of the solar system. The train has a gentle slope and looks like a giant shield, the same thing that Captain Captain is holding, and the two are very similar, with a 600-kilometer diameter of the bottom entrenched ring area larger than the land area of Great Britain, and its internal volcanic cavern can fit the entire island of Hawaii.

It is unthinkable that such a large volcano could be found on Mars, which is much smaller than Earth.

Regardless of the strong winds outside, there should be no sandstorms inside the crater. So Alice's mention is very feasible.

"Will there be Martians in the crater?" Erdan said suddenly, a little afraid, and a little expectant.

Alice smiled, patted Erdan on the shoulder again, and said, "Now that the sandstorm has affected most of Mars, there is no place safer than this crater." If the Martians really exist, it is really possible to hide in them. But don't be afraid, I'll protect you. Brother, from now on, Alice will cover you, and whoever dares to bully you will abuse him, and beat him all over the ground, even if my opponent is a country or an alien civilization. ”

Erdan was stunned, "Alice, why did you snatch my lines?" ”

"Love, it's all the same! Now let's head to this extinct volcano. Alice said shyly, "I haven't finished teaching me the eighteen kissing styles you taught me." Moreover, I seem to have forgotten what I taught. ”

"Forget it doesn't matter, you can teach it again, plus 108 styles in bed for men and women."

Yes, Type 108, I can't finish it until dawn in the South China Sea!

It is normal for lonely men and widows to be alone in the space and unable to hold on. Besides, they have nothing to do but be affectionate.

The flying saucer starts and flies towards the Olympus volcano on Mars. Whether it is a blessing or a curse waiting for Alice and Erdan, we will know when we get to the ground.

In the minute or two when the two of them rushed to the volcano, they talked about Mars, after all, Mars is still very talkative.

The nine planets are arranged in this way according to their proximity to the Sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto.

It seems that recently astronomers expelled Pluto from the list of the nine planets in the solar system because it was too small, and now it has become eight planets. But it doesn't matter, I won't discuss it here, who let Pluto get too far away from Earth. If one day Li Erdan drove a flying saucer to Pluto, and it has an impact on the direction of this book, let's talk about it again.

Among the nine planets, Venus and Mars are the two "neighbors" of the Earth, of which Mercury is the closest to the Earth, and Mars and the Earth are the most similar. At present, humans on Earth are more interested in Mars, sending more than twice as many probes as Mercury. The remaining seven planets have also been detected, but fewer probes have been launched, including Pluto, which is farthest from Earth.

The probe to detect Pluto is the "Horizon" made by Millican, which has been flying on the road for more than ten years, and finally flew to Pluto after a lot of hard work, and now it has circled Pluto, as for what he found, Millican did not announce it. In fact, we ordinary people don't care, what is love.

Mars is known as terrestrial planets, that is, planets that bear a strong resemblance to the structure of the Earth. Among the nine planets, the three stars of "water, fire, and gold" are all terrestrial planets. They are close to the sun, have plenty of light, and the temperature is not too high nor too low; The size is about the same size as the Earth, so the gravitational acceleration is not too different; All are made of rocks; There is an atmosphere in zài; Wait a minute. Since these three planets are "earth-like", and the earth has life, it is very likely that they will also have life. At least, that's what astronomers think. Mars and Earth have the highest degree of similarity, and the probability of life is also the highest.

Mars is the second most thoroughly studied extraterrestrial planet after the Moon. Although it is the second thorough, the earthlings still did not even touch the fur of Mars, only the dust on the fur.

Since the Soviet Union launched the first Mars rover "Mars-1" in 1962, more than 50 probes have been launched to Mars. Among them, Millican and the former Soviet Union and Russia have the most, and they are almost "equally divided into the world", and the remaining few places are occupied by the East and Europe, as well as the unexpected three countries of Afghanistan, and as a space power, we in China do not have one. But don't worry, we are a thick explosion, we will never fight an unprepared battle, now we are fully prepared for the launch, and strive for success at the first time, unlike Milliken and the former Soviet Union, the first one failed. Well, we have already failed the first time, and that is the "Firefly 1", but we will strive for the success of "Firefly 2", and the launch date will be in the next two or three years.

The Earth has launched so many Mars probes, and the harvest is quite a lot, although it only touches the dust on the fur of Mars.

The diameter of Mars is almost twice that of the Moon, half of the Earth, the inclination of the axis of rotation, the rotation period is similar to that of the Earth, the day and night are the same as the Earth is 24 hours, because it is a little farther from the Sun than the Earth, the orbital period is long, and one year is two years of the Earth.

It can be seen how similar Mars and Earth are! Of course, there are also many dissimilarities, for example, our earth has a lot of water, it looks blue, Mars has no water, or there is water, but the little is pitiful, negligible, the surface is covered with hematite slag, and the rocks, like deserts, look orange-red, that is, the color of rust.

The iron ore reserves on Mars are amazing, and when the iron ore on the earth is mined, it can be mined on Mars, and there should be no pressure to mine it for thousands of years.

The moon has a lot of helium-3 reserves, Mars has iron ore reserves, Jupiter has a lot of ore reserves, and Venus ,......。 Alice also said that she had seen a planet full of diamonds, agate, and emeralds. It can be seen that every planet has a treasure. As long as Li Erdan wants to make money and bring any treasure on the planet to the earth to sell, he can easily become the richest man in the world, and it is not impossible to compare the Rothschild family with the Louis family. It seems that Li Erdan doesn't have this consciousness now.
