And in the cabinet meeting a week ago, the Ming Empire's restriction that Zhu Lei must not be involved in civilian industries was also canceled, but it was not completely canceled, in the civilian industry, it can only involve various industries in space, and in the various civilian industries on the planet, it cannot be involved, even if the transformation of Mars is completed in the future, he must not involve the civilian industries inside.

Although Zhu Lei is not allowed to participate in the things on the planet now, but in fact, he doesn't care about the various civil industries on the planet, after all, he already has a company operating in various civil industries on the planet, although this company is nominally a royal industry, but in essence he still has an absolute controlling stake, although in the past ten years, this company has undergone various changes, and he now only has 51% of the shares, but this cannot change the fact that he has absolute control.

After all, his 51% stake is concentrated in his hands, and the other 49% of the shares are not only the royal family and the royal family, but also the shares of the aristocratic family, merchants and commoners, so the actual owner of this company is still him.

So it doesn't matter if he doesn't participate in the civilian industry on the planet, after all, if his current Yongan Group participates, then the survival of this company will become a problem, and the existence of this company will also solve most of the contradictions of the Ming Empire on the planet.

After all, Zhu Lei eats meat, and he also has to give a little soup to others, if the food is too ugly, then it will be too hateful.

And the industry in space, since the pigpen has opened up the right to buy plasma thrusters and anti-gravity engines, which is actually equivalent to giving its shipbuilders a mouthful of soup to drink.

After announcing the release of the right to purchase plasma thrusters and anti-gravity engines, Zhu Lei also launched a new spacecraft program at the shipyard on the moon, in addition to military ships, this time Zhu Lei also launched a special-purpose spacecraft project.

Among them, the space mining ship is one of the many projects, and this is also a very important project, after all, as the pace of human beings involved in space is getting deeper and deeper, the dependence of human beings on space resources will be higher and higher in the future, and this requires a large number of space mining ships and space transport ships.

Before, whether it was the military of the Ming Empire or Zhu Lei's own Yongan Group, they all focused on military ships and passenger spacecraft, so until now there are still very few large cargo ships in the Ming Empire, and there is not even one space mining ship until now, so most of the space mining ships launched this time have a tonnage of more than 100,000 tons.

However, on the cargo spaceship, Zhu Lei did not manufacture it, because the cargo spaceship is now the state-owned spaceship shipbuilding company of the Ming Empire, and now it has begun to manufacture, and the tonnage exceeds 500,000 tons, all of which belong to the second-class spacecraft.

This time, Zhu Lei's spacecraft research and development center has designed a total of three space mining ships, the largest of which is the aforementioned space mining ship with a tonnage of more than 100,000 tons.

The smallest tonnage is less than 500 tons, not even a spaceship, it can only be regarded as a space mining vehicle, although this kind of spacecraft has the smallest tonnage, but in fact, the use of this space mining ship is currently the largest.

This ultra-small spacecraft is also equipped with an electromagnetic shield generator, which can defend against the attack of the spaceminer by the solar wind, and the energy it uses is the same energy as the previous ordinary spacecraft.

The tonnage of this mining ship itself is about 480 tons, and the length is less than 50 meters, but don't look at the tonnage of this space mining ship, the overall size of the spacecraft is also very small, but its power is very strong, it has four powerful plasma thrusters, it can drag ore more than a thousand times its own mass.

In other words, this spacecraft with a volume of less than 50 meters and a mass of only about 480 tons, but he can drag about 480,000 tons of ore, which can be said to be a very amazing data.

And the speed of this spacecraft is not slow, in the case of no cargo, this spacecraft can reach the fastest speed of light 0.2%, that is, about 600 kilometers per second, such a speed is already very amazing, after all, the size of this spacecraft is only so big, this kind of space mining ship can only mine in the asteroid belt at most, and even the outer periphery of the solar system can't go out, let alone mine outside the solar system.

However, due to the very small size of this space mining ship, it can be carried as a sub-ship of a large space mining ship.

The second type of space mining ship, its tonnage is about 10,000 tons, the length is about 150 meters, this kind of space mining ship is installed on the ordinary nuclear power equipment, which can charge the batteries on the spacecraft, and this space mining ship can also drag about 1,000 times its own weight, that is to say, this space mining ship can drag about 10 million tons of ore.

The last kind of space mining ship is the aforementioned 100,000-ton space mining ship, the length of this space mining ship is more than 200 meters, this kind of space mining ship due to the use of controllable nuclear fusion technology, as well as plasma thruster technology mixed use, so the power of this space mining ship is quite strong, he can drag more than 10,000 times his own weight, that is to say, a 100,000-ton mining ship can drag an asteroid weighing about 1 billion tons.

However, the last kind of space mining ship, due to the immature technical conditions, the controllable nuclear fusion technology has not yet been completed, and it will not be able to start manufacturing until at least three months later, and the time required for manufacturing is at least half a year, that is to say, this kind of spacecraft will not be able to enter the sight of everyone in the Ming Empire until at least September next year.

However, the other two types of space mining ships are different, and there are no technical difficulties anymore, so construction can start immediately. And the first kind of space mining ship, the time required from the start of construction to the completion is very short, after all, the shipyard of Zhu Lei's spacecraft research and development center is very advanced, and all the positions in it have been replaced by robots, so the efficiency is very high, like such a spaceship of less than 1,000 tons, his shipyard can complete all the manufacturing in ten days, such a speed is simply a god speed compared with 20 years ago, Even now, there is no shipyard in the Ming Empire that can compare with the shipyard of the Spacecraft Research and Development Center.

Even the 10,000-ton space mining ship can be built in less than a month.

However, due to the limited shipyard shipyards of the spacecraft research and development center, only two shipbuilding platforms can be freed up to manufacture space mining ships, after all, in addition to space mining ships, the spacecraft development center still has many plans to be carried out, especially the manufacture of military spacecraft, which is absolutely indispensable.
