As Nguyen Lin expected, the indicator continues to work after such a long time.

The human eye does not have corresponding sensory cells and cannot observe ultraviolet beams. After the conversion, it is also necessary to simulate a visible image in false color.

The current Titan is also 1,300 kilometers away from the location of the indicator.

"WIT, photoelectric conversion, color simulation, I need to see this ultraviolet beam on the screen." Ruan Lin is now a little anxious.

In less than five seconds, the conversion was complete.

I saw that the 'sharp sword' in the lower part of the indicator was aimed straight at a certain point of Europa, and the six flying wings around it began to run at full speed, and they were moving around the main body of the spacecraft in a regular compass motion, as if collecting energy.

The ultraviolet beam emitted by the indicator, after the image is converted, Ruan Lin can clearly see the lilac laser directly emitted by it, as if it is a straight line with no end in sight. The visible width of this straight line is about 40m. Far beyond the diameter of this indicator. Its power consumption in those few seconds is terrifying! And the energy it produces is also incalculable.

The 5 milliwatt laser emitter that children on Earth play with can cause permanent vision damage if they accidentally shoot directly into both eyes. Hand-held laser-emitting toys are only about 1 watt, but they can still ignite clothes or burn our skin.

The energy emitted by the pointer first burns the atmosphere on Europa's surface in a very short period of time. Make it directly converted to the plasma state.

It then passes through the atmosphere, causing the ice and permafrost on Europa's surface to be rapidly heated to an incandescent state within 100 seconds, and finally a large hole is broken through at a precise location.

That's the right answer! Once you arrive on Europa, your questions about the indicators and even about this extraterrestrial civilization will be solved.

But Jupiter is now about 670 million kilometers away from Mars. At the fastest flight speed, it would take another year for Ruan Lin to reach Jupiter. After that, you have to reach Europa, and the fuel consumed will increase exponentially.

It is necessary to use a gravitational slingshot to accelerate the spacecraft and save fuel. In Ruan Lin's plan, Titan must carry out two gravitational slingshot accelerations of Mars and Jupiter.

The simplest example is that when Titan passes near Mars, it will be affected by the gravitational pull of the planet and change direction along a hyperbolic orbit.

The planets are also moving at a high speed without interruption. The average orbital velocity of Mars is 24.13 km/s, which is greater than the speed of Titan.

The gravitational pull is mutual.

If Titan flies behind Mars, Mars will also be slowed down by Titan, and the kinetic energy that caused Mars to slow down is transferred to Titan. It's just that the mass of Titan is too small relative to Mars, and the impact is almost negligible.

Until then, Nguyen Lin must be fully prepared.

In order to deal with the dangers that may arise on Europa, Nguyen Lin must first build more hydrogen bombs as soon as possible!

Building a hydrogen bomb is as simple as making a toy for Ruan Lin.

To build a hydrogen bomb, you first need to make an atomic bomb and use it as a fuse.

But the two are not simply bundled. Because the hydrogen bomb is the nuclear fusion of the element hydrogen, and nuclear fusion requires high energy to overcome the repulsion between the nuclei, and this high energy is high temperature. It's about 40 million K, and this temperature has to be provided by nuclear fission in the atomic bomb.

The heavy hydrogen required for the hydrogen bomb can be easily extracted in the Martian underground and atmosphere.

Ruan Lin's headache is uranium-235, the raw material for the atomic bomb, which is an extremely scarce resource on the planet, and the uranium ore available for mining on the earth may only be about 5 million tons.

The spacecraft's fuel also needs to be mined for uranium ore refining, which in turn takes a long time to replenish.

So before starting these big constructions, it is very necessary to lay more robot assembly lines.

Ruan Lin looked at Jupiter's location, and at this time he was like a nagging old woman: "Wit, record all the data, and then we need to return to the location of the surface robots." The next step is to continue building.

We need to build a rudimentary base outside the ship to keep out the Martian sandstorm. We now need to lay out a few more robot assembly lines. From this nesting doll, I need Mars to bloom everywhere! ”

Ruan Lin stroked the porthole of the Titan: "And in order to combat the strong radiation of Jupiter, the Titan must use titanium metal several centimeters thick to mask the electronic instruments inside. Without the use of titanium shading, the visible light camera and astronomical telescope carried by Titan would have been scrapped after only 7 orbits around Jupiter. This renovation work also needs to be put on the agenda. Also, I'm going to design a uranium refining robot that's suitable for Mars! In addition to refueling, create a number of small hydrogen bombs. And you also have to spare some computing power to cooperate with me to complete the theoretical refinement and manufacturing of quantum computers. ”

WIT didn't think Ruan Lin was nagging: "The specific pointing location of the laser pointer has been recorded. I take care of the rest of the production. Transforming the Titan won't take us much time. ”

After Ruan Lin planned to build a quantum computer, he would upload his consciousness. His body will be sent to the sleeping pod to be frozen.

Consciousness is immortal, and Ruan Lin can be said to be immortal.

The construction soon began, and the remaining robots on Mars began to build an initial improvised base not far from the ship. This will be a new starting point for Nguyen Lin.

All the robots are working in an orderly manner under the deployment of WIT.

In less than 12 hours, the first simple base was built, and the next step was to lay more robot assembly lines in the base.

This is followed by matryoshka work, and the assembled robot is about to be driven to the next location for base laying. Until the quantity is sufficient, they will be able to mine uranium ore and extract heavy hydrogen.

At this time, Ruan Lin also completed the design of the first material refining robot. The robot is also equipped with two tracks based on the rugged terrain of Mars.

Above his 'chest' is a small gas centrifuge that consumes too much electricity. Ruan Lin also attached an oversized battery to its back. Further down are the collection units, where the uranium ore mined by the excavation robots is delivered to them, where the all-important refining step is completed.

The refining base is composed of such robots, which will save a lot of materials and electricity without the need to build a refining base.

In less than an hour, WIT opened a new production line for refining robots.

The first refining robot also started work in earnest.

Ruan Lin can see its perspective from the screen: it is like a tireless overseer, watching near the excavation robot, which will hand over the brown uranium ore to it after it has mined it, and its mechanical arm will put it into its own 'mouth', and then pass through a gas centrifugal separator with up to 20,000 revolutions per minute in the body to continuously increase the concentration of uranium-235, and finally the extracted high-concentration uranium-235 will be put into the inner chamber.

Mars is full of such hot scenes at this time, and the big construction plan before leaving Mars begins!
