Chapter 613 (2/2)

As the task was assigned, soon the scheduled departure time came, and all the personnel on the spacecraft were in place one after another, waiting for captain Qiu to give the order to start.

”The scientific research survey ship Dijiang is ready for departure!” after putting down his children's private affairs and receiving the task, Captain Qiu picked up the walkie talkie in the bridge and asked the ground command center.

The ground command center also replied as soon as it received the request of the Dijiang.

”Dijiang scientific research ship, this is the ground command center. We have received your request and can set sail. I wish you a safe journey. Now please leave the Earth Moon system with the assistance of the pilot aircraft.” the ground command center replied!

With the command from the ground command center, the Ziwei space station immediately flew out a space fighter to guide the Dijiang to float slowly into the distance.

After all, human activities in the space of the Earth Moon system are becoming more and more frequent. A large number of aerospace vehicles and spacecraft are active in the Earth Moon system. Large spacecraft such as Dijiang are extremely inconvenient to operate in the Earth Moon system. If there is no pilot aircraft, it is very easy to collide with other spacecraft.

Although such a collision is nothing for a large spacecraft like Dijiang, it is extremely fatal for small spacecraft or aerospace vehicles.

After all, Dijiang has a huge body and heavy armor. Even if it is armored by aerospace aircraft or small space aircraft, it is impossible to destroy its armor. Once small aircraft or aerospace aircraft collide with it, it will definitely be powdered and broken.

It was to prevent such things from happening, so when Dijiang was manufactured, Wang Bin and his team had formulated the flight rules of the Earth Moon space vehicle.

As Dijiang flew away from the Ziwei space station and continued to accelerate, Wang Bin and the people in the command center quietly watched the video of the spacecraft flying away on the screen.

Ziwei spacecraft is a large-scale spacecraft. In addition, it uses a controllable nuclear fusion reactor to provide power for the spacecraft, so the spacecraft does not need to worry about energy. In addition, with the frequent activities of human civilization in the Earth Moon system, it does not circle the earth first like other aircraft and use the gravity of the earth to make the spacecraft obtain a greater initial speed.

But fly away from the Earth Moon system directly under the guidance of the pilot aircraft, and then fly directly to the depths of the universe and the direction of Mars.

When the spacecraft flew out near the Ziwei space station and reached the lunar orbit, the speed of the spacecraft had reached 50 kilometers per second.

After all, the power of the spacecraft is provided by an ion medium engine, and the specific impulse of the ion medium engine is definitely not comparable to that of an ordinary chemical rocket engine.

In addition, the ion medium engine used by the spacecraft is the latest engine of Tiangong technology. Each engine can provide hundreds of tons of thrust for the spacecraft.

Therefore, even if the engine of the previous spacecraft was not turned on at full power, its thrust was only about one-third of the highest value, but the spacecraft had reached a speed of 50 kilometers per second at this time.

However, the engine of the spaceship did not slow down and speed up for the speed increase of the spaceship, and the speed is still increasing.

In fact, if it weren't for captain Qiu and others, in order to take care of those scientific researchers on the spacecraft, they didn't need to speed up so slowly, and they could speed up with full power.
