Because the system prompts that the alien spaceship is on Europa.

If you want to find this ship, you have to lay it out in advance.

But how to design this satellite.

Now it's also a problem.

Although now Long Han can have the ability to make satellites.

However, the satellites designed by Longhan Technology are all small satellites.

It's okay to provide an Internet service.

The level of detection is so-so.

Fortunately, Su Han now has the ability to acquire aerospace mid-level technology.

It should be possible to build more powerful satellites.

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

Aerospace technology is one of the largest categories of all Suhan's technologies.

Upgrades are also the most expensive.

Just one project costs four trillion Chinese coins.

However, this is nothing to Su Han, who has a net profit of more than 10 trillion a year.

Su Han donated the money to the Xinlong Foundation this time.

Among Su Han's public welfare projects, the Xinlong Foundation currently burns the most money.

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

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

Once again, it shook the world.

Four trillion Chinese coins are equivalent to more than 600 billion meters of gold.

Now the second-richest people on the list are not convinced, and all of them are not worth so much money.

And Su Han donated all in cash.

Naturally, it is not comparable to those paper billionaires who rely on stocks, real estate, and securities to pile up.

It's just that what makes countries around the world blush is that Su Han's money is donated to Huaxia.

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

But Su Han didn't bird these people at all.

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

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

I rely on excellent products.

without buying their own products.

You don't have any products available.

I make money by my ability.

How you spend the money you earn is also your own choice.

It's nothing to do with anyone else!

……

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

The body of knowledge gained this time is very powerful.

A lot of black technology makes Su Han simply breathtaking.

There are even space weapon systems in it.

High-power laser weapons can shoot through the atmosphere.

From outer space it is possible to burn out missiles inside the atmosphere.

There are also completely new radar systems that can be anti-stealthy with the transmission of tiny photons and microwaves.

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

Of course, there are also some super fighter design methods.

These are almost all well ahead of their time.

In fact, Su Han has long wanted to lay out the production of weapons.

Especially space weapons.

Because now a lot of Su Han's net worth is in space.

If you don't have the ability to protect yourself.

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

In any case, you have to create high-energy laser weapons to protect your space station and base from being affected.

However, it is best to keep a low profile as much as possible so that no one can know about the creation of weapons.

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

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

And not only can it be launched from the air.

It can also be recovered by air.

That's awesome.

Because take-off and landing are generally the riskiest part of the rocket launch.

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

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

It also significantly reduces fuel consumption.

Increase the payload.

Naturally, there are many benefits.

The only problem is that this unmanned aerial system needs to be wirelessly transmitted over short distances to support its large energy consumption.

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

But he has chameleon batteries.

Its power far exceeds the needs of wireless power transmission.

It's just that it is troublesome to design and produce such a super-large UAV take-off and landing platform.

Many critical parts have to be redesigned and produced.

Naturally it takes a little time.

There is also a new graded ion engine in the black technology.

Although Longhan Technology already has its own ion engine.

And it has been applied to the Tianlong satellite and the lunar space station.

But the thrust of these ion engines is pitifully small.

Only milli-bull thrust.

It's okay to maintain the track height in normal times.

It's a bit of a stretch to propel large devices.

This staged ion engine can produce a thrust of more than 1,000 N on a single unit.

The thrust is certainly amazing.

However, a 10MWh power supply system is required to generate such a powerful thrust.

This amount of electricity requires nearly 1,000 square meters even with nuclear solar panels.

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

Su Han had no choice but to reduce the size of its design.

Su Han decided to design a small staged ion engine with a thrust of 20 N.

It is believed that the performance of these small engines should be far better than that of current ion engines.

Of course, these technologies are only the tip of the iceberg of Su Han's new aerospace black technology.

Now Su Han has made all-round progress in rocket launch, satellite platform, material technology, remote control technology, and application technology.

As time goes by, Su Han will slowly upgrade all the rockets of the vast company.

And it's not just space rocket technology here.

There is also aircraft building technology.

However, Su Han did not have the idea of entering the field of weapons manufacturing in a high-profile manner.

For the time being, the related technology can only be hidden.

[It's not that the cat doesn't want to write about weapons technology.] It's just that there are too many places that are easy to violate now. In general, there are two categories that cannot be touched, this cannot be touched and that cannot be touched. In order not to get into trouble! Weapons technology is on hold for the time being. Thank you for subscribing, monthly passes, and recommended tickets for supporting the creation of Huamao. Thank you! 】

……

After obtaining a variety of aerospace black technology.

Su Han's level of satellite production and manufacturing has also been greatly improved.

Although the original purpose was to produce a detection satellite that was ahead of its time.

Used to detect Europa.

But due to the improvement in the level of satellite design.

Let Su Han think of a Fang Eucalyptus who strengthened the Celestial Dragon Satellite.

In fact, the current shortcomings of Tianlong satellite.

It has gradually emerged.

With a significant increase in the number of free users.

The traffic rate gradually reached the upper limit.

If it's all calling, it's not a big problem.

But with the popularization of smartphones, more and more people are surfing the Internet, and the burden on bandwidth is also increasing.

Tianlong's solution is to increase the number of satellites per unit area.

But this situation is only a symptom and not a cure.

The technology in Su Han's mind now can create a satellite array technology.

The new satellites don't just have more bandwidth.

This combination of satellites also includes huge relay satellites.
