Everyone can finish their own work in less than an hour, and then their own time.

During this time, everyone has his own way to pass the time. Some people like to exercise, some people like to play basketball, some people like to raise flowers and plants, while Yang Lili likes to read quietly. She placed 20 books in her room early. Reading these books is the task she arranged for herself this time.

"It's also a good thing to mine asteroids. I finally have time to read my favorite books." Yang Lili said comfortably in bed.

You can enjoy the scenery outside in your spare time. At the beginning, you still feel very novel, but it becomes boring when you see more.

After 40 days of flight, endeavour finally reached the asteroid belt.

"Turn on the reverse engine!" Yang Lili has sat in the cab, operated the spacecraft and began to slow down. Under the action of the reaction force of the engine, the speed of the spacecraft slowly decreased.

At the same time, the detection radar is fully powered on and starts to check everything around in an all-round and three-dimensional way. The function of the detection radar is not only to check the content of various minerals in the asteroid, but also to detect the surrounding environment and prevent accidents.

Defenders are always ready. Once they find an asteroid threatening endeavour, they will immediately launch a laser to eliminate the danger.

Soon an asteroid appeared on their screen, displaying some basic data of the asteroid.

The small planet is about 1000 meters in diameter and has a mass of 800 million tons to 1 billion tons. 80% of it is iron and 10% is copper.

"I didn't expect that there are so many iron elements on this asteroid, which has reached 80%. This can be put into the alternative. We just don't worry. We must select the asteroid with the highest cost performance."

"Keep looking."

This is called the asteroid belt. Through astronomical telescopes, the distance between planets is very close, but when you come, you will find that it is not the same at all.

Planets are far apart. Although the location of asteroids can be found through previous exploration, it often takes a day or two to reach another planet, but there is no absolute difference.

This time endeavour decided to work in the asteroid belt for a month, during which the positions of the planets found will be marked and recorded.

Whether valuable or worthless.

"Eh, there are two asteroids rotating each other in front. This is Gemini."

The personnel on endeavour immediately studied the two planets, emitted detection light, calculated their own element composition, and then calculated the weight, volume and running speed of the two planets.

"Gemini 1 is about 300 meters in diameter, 80% of which is sulfur. Gemini 2 is about 320 meters in diameter, 30% of which is sodium and 60% of which is hydrogen."

The two planets have roughly the same weight, otherwise they won't rotate around each other. After listening to this, Yang Lili shook her head: "they're not what I want. Their value is too low."

Such an asteroid can't even count as a spare tire. If it is really pulled back, it will really become an international joke.
