Vol 3 Chapter 297 eleven thousand six hundred and five

In this way, although its mass has increased, the energy consumed during take-off has also increased, and the acceleration in space will take longer, but the attitude stability of the spacecraft has also been greatly improved, at least in normal conditions. In this case, uncontrollable spins will not occur in the universe.

Short and powerful, this kind of tractor spaceship can be described as such. Except for two reactors and spare parts, the reserved space is not large, and the crew is compressed to ten robots, eight of which can carry humans. Consciousness descends.

The tractor spacecraft does not have its own name, but they all have their own numbers, starting from number 1 and may continue to number 10,000.

Four years ago, right in front of Yang Qing’s eyes, two spaceships, No. 1 and No. 2, set off from the moon’s airport base and flew towards the asteroid belt.

Although the optimized spacecraft can reach a maximum speed of one-fiftieth of the speed of light, the speed of these two spacecraft is only one-thousandth of 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 all robots, which are basically not affected by the acceleration of more than 50 G.

The asteroid belt is 329 million to 478.7 million kilometers away from the sun, and 170 million 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 move toward You can reach it by flying away from the sun.

One-thousandth of the speed of light is also 3,000 kilometers per second, that is to say, if everything goes well, at the highest speed, it only takes six days to enter the range of the asteroid belt.

However, in fact, it needs to go through ten days of acceleration and nearly ten days of deceleration before it can reduce its speed to 100 kilometers per second.

The rest of the time is spent mainly looking for a suitable asteroid, and it needs to be grabbed, dragged, and gradually slowed down until it enters the orbit of Mars.

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

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

The night of the moon, without the diffuse reflection light pollution of the sun, lasts for half a month. It is an excellent observation period. The moon in a near-vacuum state, without the interference of the atmosphere, is actually almost the same as the observation in space. .

And because it relies on the entire planet, there is basically no disturbance such as vibration caused by the operation of mechanical equipment.

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

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

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

The orbits of these asteroids, their speed of rotation, and even the influence of the disturbances of the large planets have been fully calculated.

In fact, inside Xiao Ai’s computing core, a standard solar system model is running in real time, including the eight major planets and their satellites.

The asteroid belt, the dwarf planets, the stars in the Kuiper belt, which are always in darkness, and everything that is discovered is also running in real time.

Because of the observations made by space telescopes, the operation of this model of the solar system cannot be said to be exactly the same as the outside, but there is almost no difference.

In fact, before the tractor spacecraft took off, their goals and routes had already been clearly marked, when to accelerate, when to decelerate, and what speed was required at what position.

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

The most expensive part of the entire spaceship is probably the tractor at the back, because it is entirely made of spiritualized metal, which is several times harder than the outer shell of the spaceship, and its tensile performance and toughness are also stronger than that of Blue Star. I don’t know how much stronger the metal is.

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

Although the 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, except for the core, are generally composed of minerals such as rocks, and a large amount of ice is indispensable.

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

Although the methane produced by the combination of hydrocarbons is also stable, its freezing point is too low and it is too volatile.

In the inner solar system, the power of sunlight is still very strong, so unless it is deep in the asteroid, there is very little condensed form of methane.

Just like what I said before, the state of the spacecraft at every moment has been predetermined, and it takes only a few dozen days from here to the asteroid belt, even if you add the time to search for asteroids~www.readmtl.com ~ It will not exceed a month.

But it took them four full years to go.

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

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

It may take ten years or even longer to take it down with thrust.

After all, the linear velocity of the celestial bodies in the asteroid belt ranges from 24.3 kilometers per second on Mars to 30 kilometers per second.

But on the outside of 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, and the asteroid belt and Jupiter are almost close together on an astronomical scale. Because of the huge mass gap, the orbits of the asteroid belt celestial bodies , disturbances often occur.

Those asteroids that break through 30 kilometers per second are produced under the influence of this disturbance.

However, Jupiter can speed up, and naturally it can also slow down. Every time the asteroid they pull is adjacent to Jupiter, it is 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, and that time is when it will fall into the embrace of Mars.
