Half-immortal civilization

(Note at the beginning: This book will only introduce the corresponding planet information according to the needs of the plot. Avoid watering.)
Liu Haibo's words made a few people think about it, but more people didn't care.In fact, practice is not an easy path after all. There are only three people on the earth who have reached the golden core stage after tens of thousands of people practiced.

The spacecraft decelerates cumbersomely and slowly in space, and the powerful engine cannot provide more thrust even if it is fully turned on; and this is already the largest engine on the earth today.In fact, even if it is a master company, after the Tiger Dan-[-] engine came out, the subsequent research has come to a standstill.Restricted by materials (including materials for energy storage, transmission, conversion, metal shells, etc.), there are basically no research topics on the Tiger Bile II engine today.And the bigger the engine, the better - you always have to consider the weight of the spacecraft, the cost, and so on.In fact, any technology pays attention to the development of miniaturization.

It's far away... The engine roared, but the spaceship didn't see much deceleration for a while.But yes, the current speed of the spacecraft has reached 2000 kilometers per second, and the engine is working at full capacity, and it can only decrease by 640 meters per minute.In fact, after so many days of operation, the engine has suffered a certain degree of wear and tear. Today's engine works at full capacity for half an hour before it has to be shut down to cool down.This is a problem that was not considered before.The thrust of the engine is too large, and the bearing force on metals is a huge test.

From a distance, we can see the bright and unique appearance of Mars. The shallow atmosphere is red from the front, but around the edge, the bottom layer is red and the upper layer is light blue.The light blue is easy to understand, it is just scattering of sunlight; and the red is because there are a lot of iron oxides on Mars.

In fact, in many cases in nature, red is related to iron.

However, as it approaches, the two small satellites on Mars have a diameter of about 13 kilometers, which can be said to be among the smallest satellites in the solar system.The gravitational force of such a satellite is too small, and a person can "launch" himself into space with a single jump on it.

As we get closer, various terrains on Mars can be seen clearly; most importantly, there are more than 40 probes, large and small, in the sky and on the ground of Mars.

Mars is a planet full of fantasy. From ancient times to modern times, there are various legends about Mars. Some symbolize disasters, some symbolize war... Anyway, it is not a good sign.

In modern times, with the development of astronomical telescopes, it was once believed that those ravines on Mars were man-made canals.But with the development of technology, this wonderful fantasy was finally blown away by the ruthless reality.The fantasies of Martians and extraterrestrial life ended with a pause.

But as the saying goes, there is no way out of doubtful mountains and rivers, and there is another village in the shade of willows and flowers. With the development of science, humans have gradually discovered that there is sufficient water on Mars. To what extent is this water sufficient?If the ratio of water to the planet is compared with that of the earth, the earth is like a desert!At the north and south poles of Mars, there is a wealth of solid water and liquid water (underground); even some lake bottoms that were once thought to be dry were later discovered to be wet!

Some people estimate that if the Martian atmosphere is too thin to guarantee the existence of liquid water on the surface, maybe Mars is still a blue water world.

Of course, in order to explore Mars, humans have also paid a huge price.Many people only saw three or two Mars probes running rampant on Mars; they didn't see that, including Huaxia, at least dozens of Mars probes all over the world failed to send!
In the initial exploration, after the rocket left the ground, it was uncontrollable; to be exact, when the rocket was ignited, it was basically uncontrollable.At this time, you can only rely on the previous calculation.For the exploration spacecraft to fly from the earth to Mars, the rocket can only provide a speed of 70 kilometers per second at most, and the speed of the earth itself must be added to this.After that, you can only rely on inertia to accurately land on Mars across a distance of hundreds of millions of kilometers.But because of the unevenness of space, the thrust of sunlight (in space, the thrust of light cannot be ignored), etc., it will cause too many unpredictable problems.This difficulty is equivalent to throwing a stone in the northernmost part of China, and accurately throwing it into a cup in Singapore; the orbit cannot be repaired in the middle, and the original calculation and thrust can only be relied on; The effect of the wind.

Today, humans are still full of enthusiasm for the exploration of Mars; and Mars is the first stop for searching for extraterrestrial life-of course, it is now ruthlessly ruined by the master company and Ceres.However, today's search for life on Mars has been downgraded from intelligent life to microorganisms.Especially the several caves around the Alsia volcano on Mars; and such caves are now found all over Mars, and hundreds of them have been discovered.This is more like the breathing channel of Mars, full of reverie; and here, a large amount of methane is erupted every day.

However, due to various reasons, the plan to send humans to Mars has not been implemented. The most important thing is of course the limitation of technology.

However, today, the master company finally broke this peaceful world.

"\(^o^), I see Olympus Mountains. It's so high, it sticks out of the atmosphere of Mars!"

"What's so interesting about that, I saw the Sailor Valley, it's such a big valley!"

"Why do you like those ditches, valleys and the like!"

"Fuck off, I'm looking at the ice cap of the North Pole. This is almost equivalent to the North Pole on Earth. It's also a frozen world."

"Look quickly, the Mars-[-] satellite, wow, it's so beautiful. From this position, it looks like a red heart in space!"

Phobos thought that there was a crater with a diameter of ** kilometers on it, and it looked like a hole was missing; and Phobos itself was about a dozen kilometers in diameter, with one end slightly pointed, and it was in a suitable position. Looking at the position, it really looks like a red heart; especially because there is a lot of water (ice) on the top, reflecting the color of Mars, you will see a red color.

"Hurry up and take a picture!"

"It's late, we're past that position. I'm watching a tornado right now!"

"Everyone, everyone, pay attention," Liu Haibo's voice sounded, "We will circle Mars at a speed of 6 kilometers for a few laps, and then land on Mars. Now everyone, please make the following preparations. First, check the status of the qualified space shuttle, Especially the power and working medium; second, check your spacesuit for damage. We may stay on your Mars for more than a month, or even more time. The specific time is adjusted according to the actual situation.”

"Captain, shall we contact the headquarters about the situation here?"

"No need, the task has already been determined before." Liu Haibo would think of Zhang Jingyuan's crazy idea every time he came to this time.
