On May 1, 2029, the weather was cloudy, and Zhou Yu and Xinghuo Technology scientists were already wearing spacesuits, and they were about to land on the Endeavour spacecraft.

Zhou Yu comforted Chen Jin, who saw him off at the door of the Endeavor spaceship, and said, "Xiao Jin, don't worry!

The safety of today's spacecraft is excellent, and the spacecraft has withstood tens of thousands of missions without a single accident.

The safety of a spaceship is more advanced than that of a high-speed train, and it is far more secure than an old-age car.

I go on a scientific mission, not to live in space permanently, at least a few days, at most a month or two and then come back. ”

"Zhou Yu, you must come back safely, I and the children are waiting for you at home." Chen Jin held back tears and waved goodbye to Zhou Yu.

"Start boarding." Zhou Yu commanded.

The scientists of Xinghuo Technology, the basic personnel of the spacecraft, and the logistics personnel began to board the ship in batches.

The Endeavour spacecraft began to levitate in the air, accelerated rapidly with the help of the sun's gravitational pull, and soon disappeared into Earth's space.

The Endeavour spacecraft is a scientific research ship, and most of the main equipment it carries is used for scientific research activities.

Zhou Yu held a meeting inside the Endeavour.

"Our target this time is the asteroid belt, and we will first go to the center of the asteroid belt to investigate the only dwarf planet there, Ceres.

After the investigation of Ceres, collect some resources and specimens of the asteroid belt, and complete the preliminary exploration of the asteroid. ”

Zhou Yu's target this time is the asteroid belt, which is the airspace in the solar system where resources are concentrated.

Most of the resources in the asteroid belt still exist in the form of asteroids, which are very easy to screen, and it is not difficult to smelt such resource-rich asteroids.

The Endeavour spacecraft flew out of Earth's orbit and, with the gravitational pull of the Sun and Jupiter, began to gallop towards the asteroid belt.

Scientists are looking at the asteroid belt.

The asteroid belt is a dense area of asteroids within the solar system between the orbits of Mars and Jupiter.

The asteroid belt is the region with the highest concentration of asteroids, accounting for 98.5% of the number of asteroids in the solar system, with an estimated number of up to 500,000, so this region is called the main belt.

It is about 2.17~3.64 astronomical units (an astronomical unit is equal to 149597870700 meters, which is about the distance between the sun and the earth).

More than 500,000 asteroids have gathered, forming an asteroid belt.

With so many asteroids being able to be condensed in the asteroid belt, Jupiter's gravity plays an even bigger role than the Sun's gravitational pull.

The asteroid belt is formed by a group of stars (planetary predecessors that are smaller than planets) in the primordial solar nebula.

However, because of Jupiter's gravitational resonance, these stars are prevented from forming planets, causing many stars to collide with each other and form many debris and debris.

The three largest asteroids in the asteroid belt are Homo sapiens, Marriage and Vesta, all with an average diameter of more than 400 kilometers.

There is only one dwarf planet in the main belt, Ceres, with a diameter of about 950 kilometers.

The rest of the asteroids are smaller, some even the size of dust.

The material in the asteroid belt is very thin, and the asteroids in the main belt are divided into three groups, carbonaceous, silicate and metallic, according to their spectrum and main form.

In addition, collisions between asteroids may form groups of asteroids with similar orbital characteristics and color, and these collisions are also a major source of dust that produces zodiacal light.

Asteroids carry 4 of the most common families of small planets, which are carbonaceous asteroids, silicate asteroids and metallic asteroids, and comet asteroids.

The vast majority of asteroids in the asteroid belt are carbonaceous and silicate asteroids.

On the outer edge of the asteroid belt, close to Jupiter's orbit, carbonaceous asteroids dominate, accounting for more than 75% of the total.

Compared to other asteroids, the color is reddish and the albedo is very low. Their surface composition is similar to that of carbonite meteorites, and the chemical composition and spectral characteristics are the same as those of the early solar system, but they lack some lighter and volatile substances such as ice.

The part near the interior, 2.5 AU from the Sun, is more common with silicate asteroids.

Spectra show that the surface contains silicates and some metals, but the composition of the carbonaceous compound is not obvious.

This suggests that they are significantly different from the composition of the original solar system, possibly due to the melting mechanism of the early solar system, which led to the result of differentiation.

These asteroids have a high reflectivity compared to carbonaceous asteroids. It accounts for about 17% of the entire population in the asteroid belt.

There are also asteroids of the third category, which account for about 10% of the total number of metal asteroids.

Their spectra contain iron-nickel-like lines that appear white or slightly red, without the characteristics of absorption lines.

Metallic asteroids are presumed to have been formed by devastating impacts of a core dominated by iron-nickel matrix. Within the main belt, metallic asteroids are mainly distributed in orbits with a half-major diameter of 2.7 AU.

Metal asteroids are people's favorite asteroids, they are simply a moving vein.

The speed of the Endeavour spacecraft was very fast, and they had only traveled for half a month before they were already approaching the edge of the asteroid belt.

The Endeavour spacecraft has been able to clearly receive the satellites placed in the asteroid belt in the early stage and transmit the signal back.

The high-definition camera on the satellite clearly captures the true face of the asteroid.

Many asteroids have rugged surfaces filled with impact craters, large and small, and many boulders of various sizes on the surface.

Like Earth, they have many trenches, rifts, and fissures on the asteroid.

Unlike the vast majority of trenches and fractures on Earth, the causes of fractures are formed by violent collisions.

Arranged in the asteroid belt of the satellites, they even passed back a wonderful video.

The center of the asteroid belt, perturbed by Jupiter's gravity, collides with a carbonaceous asteroid and a metallic asteroid.

The two small stars collided together to form a slightly larger asteroid, and a lot of material broke away and floated in the universe.

This is a very common scene in the asteroid belt, which is mainly affected by the gravitational pull of the Sun and Jupiter, and asteroids often collide with each other.

The asteroids that collide are different and will have different results.

Most of the collisions result in two asteroids shattering, forming more asteroids.

With only a few collisions, it could allow two asteroids to merge with each other to form a larger asteroid.

The Endeavour spacecraft soon flew into the asteroid belt, navigating between asteroids nimbly.

Although there are many asteroids in the asteroid belt, it also covers an extremely large area, and the gaps between asteroids are large.

Some asteroids with small voids, they are even smaller.

The Endeavour spacecraft tossed and turned, avoiding slightly larger asteroids, and even a tiny asteroid hitting the spacecraft would not harm Endeavour.

The spacecraft moved quickly in the direction of Ceres.
