Jiang Yiming looked at his hand-built spaceship, and a sense of accomplishment came spontaneously, even though it looked so simple and rough on the outside.

The original streamlined shape of the aircraft has disappeared, and it is covered with chunks of hard alloy, more than a meter thick, to withstand space meteorites the size of a grain of rice. If you look closely, these external armors look like patches with no aesthetics.

Titanium alloy is used to reinforce the internal structure of the spaceship, playing a supporting role, otherwise these one-meter-thick, thousand-ton armor alone would have flattened the original aircraft.

Ten Ark reactors were enough as a power source, but the engines were somewhat unable to keep up, and ion engine technology could only be reluctantly used. After a long period of acceleration, it was able to accelerate the heavy spacecraft to a speed of hundreds of kilometers per second.

Jiang Yiming's use of ion engines is also a last resort, and there is no problem with buying traditional chemical fuels in small quantities, but if they are in large quantities, they will be regulated, because this thing can make long-range missiles.

Conventional rockets are propelled forward by spewing high-speed gas from the tail, and the ion engine also uses the same jet principle, but it does not use fuel combustion to discharge hot gas, but ejects a bundle of charged particles or ions.

The propulsion provided by the ion engine may be relatively weak, but the key point is that the ion thruster requires much less fuel than a normal rocket. As long as the ion engine can maintain stable performance for a long time, it will eventually be able to accelerate spacecraft to higher speeds.

Compared to the Ark reactor, the ion engine is already an outdated technology, but it is easy to operate and not difficult to deal with. Fortunately, Jiang Yiming personally built the Ark reactor, and his hands-on ability has increased a lot, otherwise it would be difficult to install the ion engine on the spacecraft.

When working, the ion engine will emit a wake of blue flames, as if alien technology, and there will be no thick white smoke like traditional rockets, which is full of a high-tech feeling.

Jiang Yiming turned on all the ion engines, and the ten holes arranged in the tail of the spacecraft suddenly erupted ten streams of dark blue high-speed ion streams, which looked very beautiful: "All the engines are working normally, there is no problem." ”

With the Ark reactor providing the energy, the power of the ten ion engines is also very powerful, and after ten minutes, it has begun to push the heavy spacecraft slowly and glide slowly.

Don't look at the fact that it takes so long to take ten minutes, compared with the ion engines of other countries, the acceleration time of a few hours can only push hundreds of kilograms of satellites to change their orbits, which has improved the efficiency countless times.

As for the spaceship's attack weapon, there is no such thing, it is all up to Jiang Yiming to clean up the threat by himself. Who made him not know how to make weapons that can be used on a spaceship, and it is already remarkable to be able to barely install an ion engine.

"It's really an inferior spaceship, but it's not bad to use it for transportation, and it can save a lot of mental power." Jiang Yiming looked at the spaceship in the spacious warehouse and sighed.

Under the dark night, the original No. 1 spaceship was wrapped in a thick white fog and began to slowly rise into the air, this is Jiang Yiming transformed into a green Jiao, pulling this spaceship to space.

Why didn't he start all the ion engines? Because the instantaneous burst power of the ion engine is insufficient, it cannot get the spacecraft weighing several thousand tons out of the earth's gravity, and it is useless to accelerate for a long time.

What's more, the ion engines are all located at the tail of the spacecraft, which can only provide forward acceleration. Individuals build by hand, and naturally it is far less than the spaceship designed by the power of the state, and it can only be like this.

Jiang Yiming pulled the spaceship weighing several thousand tons, and he didn't feel too hard. It's just that the distance of 500 kilometers away from the dense atmosphere of the earth, that is, the lift-off, took much longer than the last time he was alone, and it took half an hour.

This is because the spacecraft is huge, and it can only sacrifice speed in order to conceal it, especially when it first lifts off in Hong Kong, it can only slowly rise to avoid the detection of Huaguo's radar.

After arriving at 500 kilometers, Jiang Yiming started the spacecraft's ten ion engines, and the brilliant blue tail flame erupted for more than ten meters, which was extremely beautiful. However, this beautiful scenery also has a disadvantage, that is, it is out of the white fog and exposed to the outside world.

At NASA headquarters in the United States, a female monitor stared at the screen nonchalantly, not knowing where she had flown to. Suddenly, she saw a visible image taken by a satellite, and then her eyes widened and she reported her discovery.

"What is this, the body is a white cloud, but the tail is a blue ion stream? Which country has a new stealth technology? ”

"You see, this unknown flying object is getting faster and faster, and it is almost out of the satellite's field of view, do we have any other satellites to use?"

"No, there are no other satellites anymore, and Talos 3 needs to be re-orbited to be able to observe it. Ah, it's already flown away! ”

Jiang Yiming no longer needed to contribute personally at this time. There is no drag in space, and the acceleration provided by the ion engine can keep the spacecraft accelerating, and the speed will get faster and faster, and the speed is now more than twenty kilometers per second.

The distance between Mars and the Earth is not a fixed value, but between 55 million kilometers and 400 million kilometers, and now is not the closest time for the two, it is probably more than 100 million kilometers.

"Even if it is 100 million kilometers, when the spacecraft accelerates to 1,000 kilometers per second, it will only take 100,000 seconds, which translates into 27 hours. Even if you need to slow down and double the time, it will only be more than two days. ”

Jiang Yiming calculated it and felt that it was not a waste of time to spend two or three days on a trip to Mars. Of course, he only made a rough calculation, and the specific time spent was not calculated in this way, but it depended on the power of the ion engine.

When passing by the moon, he didn't slow down, because he had already been there once last time, and there was nothing new to feel about it.

"Hey, it's not that I'm dazzled, there seems to be a big dark spot on the moon." The primordial No. 1 spacecraft passed by a very close distance from the moon, and Jiang Yiming was still in the form of a green Jiao at this time, and his eyesight was amazing, and he suddenly saw something unusual.

However, the speed of the spaceship was very fast, and the black spots flashed by, and the sight was still the desolate and dead moon surface. He plans to wait until he returns from Mars to take a closer look.

According to the space star map obtained by Li Chaoren from the United Kingdom, the original spacecraft No. 1 went straight to Mars, reaching a speed of 200 kilometers per second, and it is still accelerating.

"It's boring!" The water-blue earth is getting farther and farther away, and it is almost impossible to see, Jiang Yiming is gradually getting bored, and he doesn't even have a mobile phone to play.

The spaceship has no life support system at all, and the temperature is as low as minus 100 degrees Celsius, and no mobile phone can withstand such low temperatures. (To be continued.) )
