The Return of the Black Technology of Immortal World

In this way, although its mass has increased, the energy consumed during takeoff has also increased, and it takes longer to accelerate in space, the attitude stability of the spacecraft has also been greatly improved, at least under normal conditions. Under such circumstances, uncontrollable spin will not occur in the universe.

Short and powerful, this kind of towing spacecraft can be described as such. In addition to the two reactors and spare parts, the reserved space is not large. The crew is reduced to ten robots, eight of which can carry humans. Consciousness comes.

The tractor spaceships do not have their own names, but they all have their own numbers, starting from the 1st and possibly continuing to the 10,000th.

Four years ago, right in front of Yang Qing's eyes, the two spacecrafts No. 1 and No. 2 departed from the moon's airport base and flew towards the asteroid belt.

Although the optimized spacecraft can reach a maximum speed of one-fiftieth the speed of light, the speed of these two spacecraft is only one-thousandth the speed of light.

And to reach this speed, it will take about ten days of acceleration.

This is because the structure of the spacecraft is strong enough and the pilots are robots, which are basically not affected by accelerations of more than 50 g.

The asteroid belt is 329 million to 478.7 million kilometers away from the sun and 1.77 billion kilometers away from the Blue Star. Because it is a ring that surrounds the sun and is almost evenly distributed on the ecliptic plane. In fact, as long as you start from the Blue Star and head towards You can reach it by flying away from the sun.

One thousandth of the speed of light is also 3,000 kilometers per second, which means that if everything goes well, at the highest speed, it will only take six days to enter the asteroid belt.

However, in fact, it takes ten days of acceleration and nearly ten days of deceleration before it can reduce its speed to one hundred kilometers per second.

The rest of the time is mainly spent searching for a suitable asteroid, and needs to grab it, drag it, and gradually slow it down until it enters the orbit of Mars.

A total of 120,437 asteroids have been discovered in the asteroid belt, which seems to be a huge number. However, in a ring 150 million kilometers wide, this number is actually pitifully small. It is difficult to find them within a range of tens of thousands of kilometers. An asteroid, even a meteorite is rare.

In fact, in the past few years since entering the moon, Xiaoai has never stopped observing the universe.

The lunar night is free of diffuse light pollution from the sun and lasts for half a month. It is an excellent observation period. The moon in a near-vacuum state has no interference from the atmosphere. In fact, it is almost the same as observations in space. .

And because this place relies on the entire planet, there is basically no vibration or other interference caused by the operation of mechanical equipment.

Because it is on land and is no longer limited by the size of the launch spacecraft, the lens can be made very large.

Even though it is still a combined lens, with Xiao Ai's control, there is almost no error. Therefore, on the high mountains on the front and back of the moon, she built two lenses with far larger apertures and more functions than the Webb Space Telescope in the United States. Lots of telescopes.

After the telescope was built, the first step was to observe our solar system. In fact, so far, Xiaoai has observed more than 200,000 asteroids with a diameter of more than one kilometer in the asteroid belt.

The orbits, speeds of these asteroids, and even the effects of disturbances from large planets have all been fully calculated.

In fact, inside Xiao'ai's computing core, a standard solar system model is running in real time, which includes the eight major planets and their satellites.

The asteroid belt, dwarf planets, and those stars in the Coinber belt that are always in the dark, all that are discovered are also moving in real time.

Because of the observation by space telescopes, the operation of this solar system model cannot be said to be exactly the same as that outside. It can only be said that there is almost no difference.

In fact, before the towing spaceships take off, their targets and routes have been clearly marked. When to accelerate, when to slow down, and what speed is required at what position.

In fact, what the towing spacecraft does is to fly to a suitable location, spread the net, wrap an asteroid, and then connect the towing rope to the tractor behind the spacecraft.

The most expensive part of the entire spacecraft is probably the tractor at the back, because it is entirely made of spiritual metal. It is several times harder than the outer shell of the spacecraft, and its tensile strength and toughness are also stronger than those of Blue Star. I don't know how much stronger metal is.

Only such a tractor can pull an asteroid with a mass of several billion tons.

Although asteroids have different compositions, even if they are made of pure gold, they will not exceed 20 billion tons.

Moreover, the vast majority of asteroids, in addition to their cores, are generally composed of minerals such as rocks, and indispensable large amounts of ice.

Because the material originally formed in the universe was hydrogen atoms, and the water formed by the combination of hydrogen and oxygen is also more stable.

Although methane produced by combining hydrocarbons is also very stable, its freezing point is too low and it is too volatile.

In the inner solar system, the power of sunlight is still very powerful, so unless it is deep in an asteroid, there is rarely a solidified state of methane.

As mentioned before, the status of the spacecraft at every moment has been predetermined. From here to the asteroid belt, it only takes a few dozen days. Even if you include the time to search for asteroids, it will not exceed one moon.

But it took them four full years to leave.

The main purpose is to change the orbit of the asteroid numbered 11605.

In fact, even with two spaceships, the traction provided to 11605 is almost insignificant compared to its huge kinetic energy.

If we want to take it down with thrust, I am afraid it will take ten years or even longer.

After all, the flight linear speed of celestial bodies in the asteroid belt is between 24.3 kilometers per second of Mars and 30 kilometers per second.

But outside the asteroid belt, there is a huge Jupiter.

As the second largest celestial body in the solar system, Jupiter has a huge impact on the entire galaxy. The asteroid belt and Jupiter are almost next to each other on an astronomical scale. Because of the huge mass gap, the orbits of the asteroid belt celestial bodies , disturbances often occur.

Those asteroids that exceed thirty kilometers per second are produced by the influence of this disturbance.

But Jupiter can speed up, and naturally it can also slow down. Every time the asteroid they pull is adjacent to Jupiter, it's time to slow down.

In fact, using Jupiter to slow down is the main way to slow down 11605.

After four blue star years, 11605 finally slowed down to the orbit of Mars, even slower than Mars.

And it will intersect with the orbit of Mars in two months. At that time, it will fall into the arms of Mars.
