Because the alien spacecraft prompted by the system is on Europa.

If you want to find this spacecraft, you must make an advance layout.

But how to design this satellite?

Now it is also a problem.

Although Longhan now has the ability to make satellites.

But the satellites designed by Longhan Technology are all small satellites.

It is pretty good to provide an Internet service.

The detection level is average.

Fortunately, Su Han now has the ability to obtain intermediate aerospace technology.

It should be possible to create satellites with more powerful performance.

Su Han decided to upgrade aerospace technology to intermediate level in one go.

Aerospace technology belongs to a super-large category among all Suhan's technologies.

The upgrade costs the most.

Just one project costs 4 trillion Chinese coins.

However, this is nothing to Su Han, whose net profit exceeds 10 trillion yuan in a year.

This time, Su Han donated the money to the Xinlong Foundation.

Among Su Han’s charity projects, the Xinlong Foundation is currently spending the most money.

Otherwise, the general foundation would have really digested so much money.

Su Han donated another 4 trillion Chinese coins to the Xinlong Foundation at one time.

It shocked the world again.

Four trillion Chinese coins are equivalent to more than 6,000 billion meters of gold.

Now the second richest man who is not convinced by the rankings does not have that much money.

Moreover, Su Han donated all the cash.

Of course, it is not comparable to those paper-based rich people who rely on stocks, real estate, and securities.

But what makes countries around the world jealous is that Su Han’s money is donated to China.

Although many international charitable organizations also want to ask Su Han to donate.

But Su Han never had these people.

This also made many people criticize Su Han for making money from the whole world but not contributing to world charity.

But in Su Han's opinion, the money he earned was not given by others.

I rely on excellent products.

Don't buy your own products.

You have no products available.

I make money by my ability.

No matter how much money you earn is spent, it is also your choice.

It has nothing to do with others!

...

After donating, Su Han once again gained a lot of relevant knowledge.

The knowledge system obtained this time is very powerful.

Many black technologies make Su Han simply amazing.

There are even space weapons systems.

High-power laser weapons can shoot through the atmosphere.

Missiles inside the atmosphere can be burned from outer space.

There is also a brand new radar system that can anti-stealth through the transmission of tiny photons and microwaves.

Stealth aircraft have nowhere to escape in front of such radars.

Of course, there are also some design plans for super fighter jets.

Almost all of these are ahead of this era.

In fact, Su Han had long wanted to plan for weapons production.

Especially space weapons.

Because now Su Han has a large amount of wealth in space.

If you do not have the ability to protect yourself.

Your rights in space may be violated by others anytime, anywhere.

In any case, you must manufacture high-energy laser weapons to protect your space station and base from affecting it.

However, it is best to keep a low profile when making weapons.

Su Han has obtained another drone take-off and landing platform technology.

In fact, a super-large drone was designed to directly bring the rocket into the air to launch.

And it can not only be launched in the air.

It can also be recycled by air.

This is so awesome.

Because takeoff and landing are generally the most risky links of rocket launch.

If such a drone take-off and landing platform can be built.

Not only will it reduce the risk of launch and recycling.

It can also greatly reduce fuel loss.

Increase payload.

Of course there are many benefits.

The only problem is that such drone systems require short-range wireless transmission to support their large amount of energy consumption.

Although Su Han does not have high-power wireless charging equipment now.

But he has a chameleon battery.

Its power is far beyond the demand for wireless power transmission.

It’s just that designing and producing such super-large drone take-off and landing platforms is more troublesome.

Many key parts need to be redesigned and produced.

It will naturally take a little time.

There is also a brand new grading ion engine among black technology.

Although Longhan Technology already has its own ion engine.

It has also been used on the Tianlong Satellite and the Moon Space Station.

But the thrust of these ionic engines is pitifully small.

Only thrust of thunder.

It is OK to maintain track height in normal times.

It is a bit unsatisfactory to use to push large devices.

This kind of ion engine can generate a maximum thrust of more than one thousand N.

The thrust is of course very amazing.

However, it takes a 10mwh power supply system to generate such a strong thrust.

Such a large amount of power even if you use nuclear solar panels, it will take nearly a thousand square meters to use.

It is inevitably a little too big to use as a weapon system target.

There is no way Su Han can only reduce his design volume.

Su Han decided to design a small trumpet-classified ion engine with a thrust of 20 nh.

I believe that the performance of these small engines should be far better than that of today's ionic engines.

Of course, these technologies are just the tip of the iceberg for Su Hanxin to acquire the black technology of aerospace technology.

Now Su Han makes comprehensive progress in rocket delivery, satellite platforms, material technology, remote control technology, and application technology.
