Chapter 351 Interstellar Exploration
Chapter 351 Interstellar Exploration
【Interstellar exploration has begun. It will be a lonely and long journey, but it is also full of charm. Next, please listen to the light music brought to you by Ark 5.0】
Soothing music sounded in the spaceship. Gu Feng ate the food made by No. [-], picked up Coke, and toasted No. [-].
The can that No. [-] picked up was not filled with cola, but an electric current drink, specially prepared for the mechanical team.
It drinks the current drink, which is equivalent to charging.
"Boss, where is our first destination?"
Zero asked excitedly.
"This trip has no destination."
Gu Feng did not lie. In 5 years, the ark floated wherever it went, and then it took 5 years to return. The scenery and information collected during the journey are all the results of exploration.
"So where are we now?"
Zero asked curiously.
Fang Zhou replaced Gu Feng to answer No.[-]'s question.
【Dear passengers, we are now in the solar system】
[Solar system: the system of celestial bodies centered on the sun and bound together by the sun's gravity, including the sun, planets and their satellites, dwarf planets, asteroids, comets and interplanetary matter.
The solar system is located about 2.4 to 2.7 light-years away from the center of the Milky Way.
The sun moves around the center of the galaxy at a speed of 220 km/s, and it takes about 2.5 million years to go around once. As a result, the earth's climate and the overall nature also undergo periodic changes of 2.5 million years.
As of now, the earth data show that the solar system includes the sun, 8 planets, nearly 500 satellites and at least 120 million asteroids, as well as some dwarf planets and comets.If the orbit of Neptune is taken as the boundary of the solar system, the diameter of the solar system is 60 astronomical units, or about 90 billion kilometers.If the heliosphere is used as the boundary, the distance from the sun to the solar system boundary can reach 100 astronomical units (the thinnest point).If the Oort cloud is used as the boundary, the diameter of the solar system may be 20 AU. 】
"Well, it's quite detailed."
Zero interrupted Ark's introduction and walked into the cab.
There is a radar display on the big screen, marking the specific location, as well as various asteroids around it.
The traveling route of the ark is far away from the solar system.
The most likely next stop is Mars, the second closest planet to Earth.
"Boss, are we going to stay on Mars?"
The mechanical dog asked again. If it didn't speak, it would feel uncomfortable.
Gu Feng also walked into the cab slowly.
This Ark 5.0 is a small spaceship with the advantage of fast speed. Unlike ordinary manned spaceships that can carry a large number of people, it has high maneuverability and defense.
"Mars, you can go and see it when you arrive, and collect some soil for research."
Gu Feng said.
"Roger that!"
Zero raised his dog's paw and made Gu Feng laugh.
……
[Ark 5.0 has arrived in the field of Mars]
【Mars, the fourth closest planet to the sun, the second smallest planet after Mercury in the solar system, and one of the four terrestrial planets in the solar system.
The diameter of Mars is about half that of Earth, the inclination of its axis of rotation and the period of rotation are similar to those of Earth, but its orbital period is twice that of Earth.Mars brightens up to magnitude -2.9, but is dimmer than Jupiter most of the time.
The atmosphere of Mars is dominated by carbon dioxide (95.3%). It is thin and cold, full of impact craters, canyons, sand dunes and gravel, and there is no stable liquid water.
The southern hemisphere is the old, impact-cratered highlands, while the northern hemisphere is the younger lowland plains. 】
Gu Feng is no stranger to Mars. Although this is the first time he has seen this reddish-brown planet, Mars has the largest known mountain in the solar system—Olympus Mons and the largest canyon—Sailor Canyon. Of all the planets in the universe, the planet most likely to have life forms.
A long time ago, someone proposed a plan to emigrate to Mars, but it is a pity that technological strength has not been able to achieve it.
It is also impossible to further detect the mysterious Mars, and the people on earth know too little about Mars.
Since it is an interstellar exploration, it will last for another 10 years. Gu Feng has time and is also obliged to explore Mars.
Ark 5.0 did not land, but first flew around the planet at low altitude to get a panoramic view.
Seeing it with your own eyes is naturally more intuitive and shocking than literature.
Gu Feng and Zero were in the cab, observing the environment of Mars through the thick glass windows.
"It's really a barren planet."
Zero sighed, looking around, there are red deserts and Gobi.
"Don't underestimate this barren planet, it is currently known as the planet most likely to have life."
Gu Feng explained with a smile.
"Boss, it is detected that the outdoor temperature is minus 55°C, and the density of the atmosphere is only about 1% of that of the earth. Is there really life in such an environment?"
Zero asked suspiciously.
"This is just a possibility, and we have to explore it to know."
One person and one dog communicated while continuing to observe.
Gu Feng took out the telescope, and after a week of observation, he got the same information as the known astronomical data.
Mars has the same diverse terrain as the earth, with mountains, plains and canyons. Mars is basically a desert planet with sand dunes and gravel on the surface.
The topography of the northern and southern hemispheres has a strong contrast: the north is a lava-filled lowland, and the south is an ancient highland full of craters, and the two are separated by obvious slopes; volcanic terrain is interspersed with many canyons. , there are polar caps composed of dry ice (solid carbon dioxide) and water ice at the north and south poles, and aeolian sand dunes are also widely distributed throughout the planet.
Eventually, Ark 5.0 landed in a cavernous region on the flank of Mars' Arsia volcano.
The opening width is 121 meters.
The reason for choosing to land here is mainly to detect the existence of life. First of all, if there were primitive life forms on Mars, these may be the only natural structures on Mars that can provide protection for life.
Second, if the conditions are right, these caves may serve as settlements for humans after landing on Mars in the future.
Data show that methane is emitted from these caves during the summer, raising the possibility of life in the caves.
The hatch of the Ark spaceship opened.
Gu Feng, who was wearing a thick spacesuit, and a mechanical dog with a vigorous gait set foot on the soil of Mars.
With the detector in his hand, Gu Feng was about to enter a cave, and checked the basic situation of the cave.
Zero's eyes automatically turned into searchlights, releasing light to dispel the darkness in the cave.
The cave is composed of rock structures, without liquid water, very dry, and the temperature is about 10 degrees Celsius higher than the outside world, but it is still not a temperature that humans can resist.
However, for the mechanical family, as long as they can develop electric energy here, they can live easily.
Number Zero is still holding various small tools in his hands, and from time to time he picks up a stone on the ground and throws it into his backpack, which he plans to take back as a souvenir.
It promised Jisha and Wusha, two compatriots with different sizes, to bring them souvenirs back home.
Gu Feng took out the instrument and measured the cave.
The cave is 500 meters wide and 130 meters deep, and it can effectively resist sandstorms in the cave.
Dust storms are the most common phenomenon on Mars.
No effective information was detected in the first cave. Gu Feng and No. 7 went to nearby caves, explored [-] caves in a row, and detected carbon materials in the largest cave.
"Is there really a living body?"
"Maybe it's just a coincidence."
"Take it back and have a look."
One person and one dog communicated, transporting a large stone slab into the spaceship.
Back in the spaceship, Gu Feng began to examine the stone to see if it was a fossil.
Finding carbon materials means that there are three possibilities.
The first type is cosmic dust.
The second, UV degradation of carbon dioxide.
The third, UV degradation of bioproduced methane.
If it can be proved that this is a fossil, then the exploration of civilization on Mars will go one step further, even a big step.
Looking at the busy Gu Feng, Number Zero finished sorting out the beautiful stones he had picked up, and asked puzzledly,
"In fact, the earth is still young, and the moon has become the second earth. Why should we explore Mars and other planets? What's the significance?"
"There are many reasons. The first is that Mars is close to the earth. This can be said to be our neighbor. Don't you think it's impolite for you to know nothing about your neighbor?"
Gu Feng made a joke, and then continued,
"Mars has a huge ozone hole, and the sun's ultraviolet rays shine on Mars unobstructed.
If we study this problem clearly, we can know what will happen to the earth once the earth's ozone layer disappears.
Although the earth is still very young, it has experienced many changes, especially the history of human beings is too short. If we do not rely on this knowledge and experience, we will be helpless when the earth faces disasters.
Research on Mars helps to understand the extreme consequences on Earth if the Earth's ozone layer disappears. "
"I see."
"The most important thing is that after you find out the reason, you can try to restore the ecological environment of Mars, transform Mars, and make it a real second, oh no, third Earth. The resources on Mars are more abundant than the moon, and the volume is also larger. Large, with a moderate distance from the sun, once the earth changes, Mars is the best refuge."
"I always feel that in your eyes, the earth is very dangerous."
Zero made a complaint.
Gu Feng wiped the sweat from his forehead, probably due to the influence of the simulator, there is always a feeling that a catastrophe will erupt on the earth one day.
But isn't the mission of scientists to plan for a rainy day?
If you really waited until that day to think of a solution, it would be too late.
After testing with sophisticated instruments, it was found that this stone is not a fossil, but a meteorite, which is the first case, cosmic dust.
Zero also imitated Gu Feng's movements, and put the small stones he picked up one by one on the instrument for testing.
For it, this is not scientific research, but a game.
"Hey, the instrument is on."
Zero said in surprise.
Gu Feng walked over with a coffee in his hand, looking at the stone placed on the instrument by No. [-] and the test results given by the instrument, his pupils dilated instantly.
"This is a fossil, number zero, you picked up the fossil."
"Huh? Fossils?"
Zero looked surprised. It just wanted to play, but it didn't expect to pick up fossils.
"Yes, this is an insect fossil, showing that life really existed before."
Gu Feng put down his coffee cup, and excitedly patted Zero's dog's head, "Where did we find it? Let's go back to that cave and dig deeper to see if we can find other fossils."
"Marked as being in Cave 3."
No. [-] replied that its memory is very good, it is almost impossible to forget, which is also the benefit of mechanical life.
Later, Gu Feng and No. [-] dug a large number of fossils in Cave No. [-], which proved Gu Feng's guess at the beginning.
Perhaps these caves were the refuges for the creatures in times of disaster.
By detecting the age of these fossils, we can judge how long life on Mars has existed, and infer what kind of disaster they encountered and finally became extinct.
Gu Feng released the mechanical bug explorers and let them continue to probe outwards. The purpose is not only to find fossils, but also to find possible oases.
If there are any remaining oases on Mars, it may be the beginning of life.
Through the study of these fossils in the simulator, Gu Feng discovered the amazing history of life on Mars.
Life existed 40 billion years ago. Mars and Earth have almost the same landforms. There are also rivers, lakes, and possibly oceans, where the first life-cyanobacteria were born.
This cyanobacteria fits perfectly with the first life on Earth.
But the difference is that Mars lacks plate movement.
This also caused the first batch of life on Mars, which has been continuously continuing and developing.
Cyanobacteria continue to evolve and become highly intelligent creatures.
In order to satisfy a certain need of cyanobacteria, they promote the birth of other life, including insects, reptiles, and mammals.
And these animals all serve the cyanobacteria.
Of course, in the end, I don’t know what caused the hole in the ozone, all the animals became extinct, and the cyanobacteria no longer existed.
"Boss, actually, I think it's better to re-create Martian civilization if you spend time studying history."
Number Zero flipped through the outdated newspapers, sat opposite Gu Feng, and said slowly.
"You don't know the joy of exploration."
Gu Feng smiled and shook his head, "Wait, recreate? What's your opinion?"
"Didn't the boss use the cosmic life tree seed on the moon? You can also use one on Mars, so that life can reappear on Mars. Maybe in a few decades, people on earth will be able to immigrate to Mars."
Zero explained.
Gu Feng was stunned for a moment, and found that Zero was right.
Instead of studying the past here, it is better to completely transform this planet.
Of course, this is also because all his probes returned to the Ark and got the result that there are no oases and signs of life on Mars.
If there are living organisms, there is no need to transform here, just wait for Mars to develop naturally.
Maybe Mars is the next Earth, but it will take billions of years to transform.
When leaving Mars, Gu Feng planted the seeds of the tree of life in the universe.
The spacecraft slowly left Mars and continued to explore.
Gu Feng wrote a paper on the history of life on Mars, and planned to publish it after returning to Earth. This is also a part of exploration, and knowledge needs to be recorded to facilitate future dissemination.
"Where do we go next?"
asked the mechanical dog.
"Jupiter."
