Although the metal elements on Blue Star are rarer than on Earth before the time travel.
But Jiang Yu is still working hard to research construction materials suitable for interstellar spacecraft.
Materials are the foundation. If we don’t even have the basic materials, how can we talk about interstellar civilization?
Finally, Jiang Yu fused nickel, titanium and other elements in a certain proportion to create nickel-titanium alloy.
Nickel-titanium alloy performs well in all aspects, has extremely high strength and radiation resistance, and is suitable for building interstellar spacecraft.
Although nickel-titanium alloy is good, its reserves on the Blue Planet are too scarce, especially nickel metal, which is so precious that it is almost calculated in grams.
“Does it have to be titanium-nickel alloy?”
"Is there no other way?"
Jiang Yu muttered to himself somewhat unwillingly.
Jiang Yu continued to search the Blue Star metal materials warehouse.
But the result made Jiang Yu somewhat disappointed and even desperate.
In addition to nickel-titanium alloy, several more ideal alloys have been synthesized.
But without exception, the reserves of these metal elements on the Blue Planet are pitifully small.
Even if all the metals on the blue planet were used to build interstellar spaceships, only a few could be built.
Not to mention building a massive fleet of interstellar spacecraft at the village, township, town, and county levels.
Jiang Yu did not inform the scientists of this hopeless result so as not to dampen their enthusiasm for scientific research.
Jiang Yu continued to study basic materials with amazing perseverance and rich knowledge base.
But as time went by, Jiang Yu became more and more desperate.
"Is it because of material problems that the technological human race cannot enter the interstellar age?"
Jiang Yu believed that there must be materials for building interstellar spacecraft on the Blue Planet, it was just that they had not been discovered yet.
But the problem is that Jiang Yu doesn't have that much time and patience to spend on basic materials, which is extremely unprofitable.
"Maybe I'm too tired these days, and my mind has gone into a dead end..."
Jiang Yu sighed and decided to relax his tense nerves first.
As an outstanding scientist before the time travel, a high-dimensional creature after the time travel, and also the owner of the system.
Jiang Yu deeply believes that in scientific research, sometimes an inspiration is more important than a hundred times the effort.
He stood up, stretched his muscles, and came to the simulated star map of the Alpha Galaxy.
Alpha Star, the sun of this galaxy, is so bright and dazzling.
There are three rocky planets and two gaseous planets orbiting Alpha Centauri.
Based on his habit before the time travel, Jiang Yu named the other four planets Venus, Mars, Jupiter and Saturn.
Between Mars and Jupiter, there is a dense asteroid belt, and outside Saturn is the Oort Cloud region.
Jiang Yu believed that all the metal elements he needed were found on other planets and asteroids in the Alpha Galaxy.
But the problem is that he can't even build an interstellar spaceship capable of traveling between planets.
How could he possibly obtain the metal elements he needed from other planets and asteroids?
At this moment, a bright spot flashed by on the star map of the Alpha Galaxy.
Jiang Yu's mind was immediately attracted, and he quickly expanded the area where the bright spot flashed.
You don’t know until you see it. Jiang Yu was shocked when he saw it.
Because he saw that bright spot flying towards the blue star.
"Asteroid hitting the blue planet?"
Jiang Yu suddenly had a bad feeling.
Although the Blue Planet also has a satellite, just like the Earth before the time travel.
This satellite also has one side facing the blue star and the other side always facing away from the blue star. Jiang Yu calls it the moon.
This satellite, like the Earth’s moon, has intercepted countless asteroids that are impacting the blue planet.
But Jiang Yu immediately made a rough calculation and concluded that the asteroid would not be intercepted by the moon and there was a high probability that it would hit the blue planet.
Jiang Yu broke out in a cold sweat instantly. He knew too well the terrible consequences of an asteroid hitting the blue planet.
"Call the director and the scientists..." Jiang Yu immediately instructed his temporary assistant.
The temporary assistant did not dare to slack off at all and hurried to call the scientists over.
Soon, one scientist after another came to Jiang Yu's laboratory.
"Your Majesty, what is it that you summoned us for?"
The Director of the Space Administration asked respectfully.
The other scientists also looked at Jiang Yu expectantly.
Could it be that His Majesty the Human Emperor has developed materials for building interstellar spacecraft?
Unexpectedly, Jiang Yu pointed to a faint bright spot on the star map and said:
"There's an asteroid that could hit our planet."
"I need you to observe and calculate it immediately."
"Calculate its course, size, and probability of impacting the Blue Planet."
When Jiang Yu said this, all the scientists were struck by lightning.
Jiang Yu was talking about asteroids that might hit the blue planet, not meteorites.
If this is true, scientists know what it will mean.
They did not dare to hesitate and immediately contacted the heads of various departments including astronomy, mathematics, physics, and supercomputing.
All departments took immediate action, and they indeed saw an asteroid flying towards the direction of the blue planet.
Observe the asteroid immediately and calculate its course, size and probability of impacting the blue planet.
Their high work efficiency allowed them to quickly reach a conclusion. The Director of the China National Space Administration reported to Jiang Yu:
"Your Majesty, after calculating the trajectory, speed, and position of this asteroid, we know:"
"Although asteroids will not hit the blue planet, they will pass by it."
"This asteroid has been flying towards the Blue Planet for six years."
