To explore the universe, we must first grasp the laws of the movement of celestial bodies.

It's like Mars.

It is the fourth planet in the solar system from the inside to the outside, affected by the movement of celestial bodies, and the parent star is about 55 million ~ 400 million kilometers away.

This 55 million kilometers refers to the Sun, the parent planet, and Mars, three points and one line.

This 400 million kilometers refers to the fact that Mars runs on the other side of the sun, Mars, the sun, and the home planet, three points and one line.

Since in the actual navigation of space, human beings do not have any propulsion system at present, which can be powerful enough to travel directly along the shortest distance between Mars and the parent star.

If you plan to go to Mars, the most time-saving and cost-saving way is to wait for the parent star to meet Mars closely, and let the launch vehicle follow an elliptical orbit, with the help of the orbital speed of the parent star, with the least fuel consumption, to throw the spacecraft to Mars.

This is known as the 'Hohmann Transfer Orbit'.

It is also the basis of Tiancheng's 'earth-moon orbit'.

However, according to the orbit of the parent planet and Mars, the two meet in close proximity and only occur once every two years.

And this phenomenon is called 'Mars opposition', and this time period is called 'launch window' for the aerospace field.

Overall, if you're going to land on Mars, or if you're going to launch a spacecraft on Mars, you'll have to wait for a 'window' that only happens every two years, and you'll have to travel three times longer than the shortest straight-line distance from your home planet to Mars to complete the entire project.

At present, the speed of the conventional spacecraft of the parent satellite is about 6~16km/s, and the range of 5500 km x 3 times of the 'Mars opposition' is calculated, and it takes at least 7 months to deploy and launch in advance.

During the long-term flight of the spacecraft, no one can guarantee that there will be no accidents, and once an accident happens, more than a billion Franklin will have to go up in the water.

Therefore, 03 has also become very important for the aerospace field.

Because after Mars and the parent star were 58.8 million kilometers away in 1988, on August 27 this year, the distance between Mars and the parent star was shortened again, breaking through to 55.76 million kilometers, which is the closest the parent star has been to Mars in 60,000 years!

Next time, we can only wait until 2018, and the rest of the time, it will exceed 60 million kilometers.

In order to welcome the arrival of Mars, major space agencies on the home planet have deployed in advance, some have launched exploration satellites, some have invested in radio telescopes that can penetrate the atmosphere, and some have launched the Hubble Space Telescope......

This is the main reason why Tiancheng has made public the 'aerospace construction contract offer' many times this year.

It's just that Tiancheng Aerospace Department did not make a plan to explore Mars, but aimed at Ceres, which is located between Mars and Jupiter, in the asteroid belt.

Well, between Mars and Jupiter, there is a huge planetary belt, and most of the meteorites that appear on the parent star come from there.

And Ceres, just inside this asteroid belt, rotates around the sun.

Its orbit is similar to that of Mars, which is also elliptical, and is divided into 'perihelion' and 'aphelion'.

When Ceres is on the same side of the Sun as its parent star, and the parent star is at aphelion and Ceres is at perihelion, the distance between Ceres and the parent star is about 159 million kilometers.

This is the closest distance between the two planets, and at a distance of 672 million kilometers.

Considering the influence of celestial orbit operation, orbit switching, daily maintenance and other factors, at the current speed of conventional spacecraft, the time to arrive at Ceres is about 3~10 years.

That is, when the shortest straight-line distance is 159 million kilometers, the spacecraft will travel along the orbit and it will take at least 3 years to reach Ceres.

When the straight-line distance exceeds 672 million kilometers, the spacecraft travels in orbit and it takes at least 10 years to reach Ceres.

Next year, when summer arrives in the Northern Hemisphere and the parent planet is at aphelion, it will usher in the shortest distance between the parent planet and Ceres.

If you miss this time, even if Tiancheng's spacecraft can use the 'gravitational slingshot' and use system resources for continuous acceleration, it will take at least five or six years to go to Ceres without a black technology engine.

And if we seize this opportunity, with the advantage of hanging, Tiancheng's spacecraft will only need one year to rush to the established orbit of Ceres ahead of schedule and meet Ceres from afar.

In order to seize this opportunity, the Tiancheng Aerospace Department made a quick decision, gave up exploring Mars, and even terminated the orbital launch project, and sent the No. 2 aircraft to drive the 'Super Sky Monkey' that would never return, and went straight to the established orbit of Ceres.

As for why explore Ceres?

Ceres is 950 km in diameter, about one-third the size of the Moon and one-thirteenth of its parent planet.

When the space shuttle in space is locked through the space telescope and analyzed by observation, the center console, which belongs to the system product, gives a hint:

It is likely to be a divergent planet, with a rocky core, a large amount of icy water in its mantle, a large number of water-carrying minerals on its surface, and a preliminary estimate of 40% of the planet's volume, in addition to the planet's ability to obtain energy from stars, a certain climate on the surface, and a suspected magnetic field. '

It is well known that three basic elements are needed for life to survive: liquid water, energy sources and certain chemical components (carbon, hydrogen, nitrogen, oxygen, phosphorus, sulfur, etc.).

According to the system, it is clear that Ceres has the conditions for life to survive, and it also has an advantage over other potentially habitable planets.

At least people don't have the ability to travel to other potentially habitable planets right now.

In addition, if today's Chenghang Taibu has denied the possibility of developing real estate on the moon, and Mercury and Venus are not currently able to play with technology, North America has not made much progress in exploring Mars for decades, Jupiter, Saturn, Uranus, and Neptune are all gaseous, and Ceres, which is located between Mars and Jupiter, has become the best choice.

However, what I never expected was ......

The space telescope in outer space, without the cover of the atmosphere, actually photographed two points of light on the surface of Ceres, and an object that resembled a pyramid.

Of course, after systematic scientific analysis, it was finally determined that it was an ocean and a volcano.

Or rather, volcanic eruptions that melt the water-carrying minerals on the surface and form an ocean that has not yet been frozen.

Since Ceres has no atmosphere, the light intensity is extremely high, and it eventually forms a reflection of one left and one right.

But......

Other countries with astronomical telescopes and space telescopes on their home planet do not have a system to help analyze them.

If it goes out......

...............

On September 21st, the Panda Guardian no longer brushed 'Ge xx', but blew up!

No matter which plate it is, it is frantically brushing up on entries such as 'alien creatures', 'alien civilizations', and 'home planet crisis'.

Even major news media, including Huaxia Channel, have also carried out long-term and large-scale objective reports on Ceres' new discovery.

It's sensational.

Even the North American fight against Iran and the anti-Japanese war parade some time ago are far less than the repercussions caused by today's news.

Coincidentally, a UFO crashed into the Great Lakes of North America last year, and this year there was an outbreak of kangaroos in Australia......

Tie them all together......

Even the parties involved, the North American NA space agency, believed it!

The first time to contact the Tiancheng 101 Laboratory, which had a good relationship with his family in the name of 'science without borders', asked for space coordinates, and then activated the Hubble Space Telescope, which he had been reluctant to use, to lock on Ceres.

Subsequently......

"Yes, indeed!"

Five hours later, not only the North American NA responded, but also the European Union Galileo Laboratory, the Nordic Astronomy Research Laboratory, the Wajima Aerospace Research Institute, the Nanyang Taimei Aerospace Information Company, the Non-Regional Alliance Space Group, and the Southern Union Space Development Company (Montenegro Odyssey), ......

'Light clusters' and 'pyramids' taken from different angles are also given.

And then.

England was shocked, "Where did you get so many space telescopes? Big brother and Northern Europe have, I believe, but you poor ghosts?"

Montenegro: "Who do you say is poor? The 200 million loan is gone." ”

England: "......"

In the aerospace industry, no one will explain the truth to the competition.

Therefore, for a time, there was an endless stream of aerospace construction orders to Tiancheng.

Tiancheng International Holdings also hung various celebratory titles on the company's official website.

"Congratulations to Tiancheng for winning the 4.5 billion Franklin Space Launch Carte Liberty construction order invested by Montenegro Odyssey. ”

"Congratulations to Tiancheng for winning the order for the construction of a 2.7 billion Franklin space launch site, invested by the African Regional Alliance (South Africa). ”

"Congratulations to Tiancheng for winning the Nanyang Taimei ......"

"Congratulations to Tiancheng ......"

"Congratulations to Tiancheng, the total amount of overseas construction orders in 03 years has exceeded 200 billion Franklin, including Dubai World Island, Dubai Submarine Complex, Greek Olympic Island, Asia-Europe Bridge, South African Railway, South African Sports System, Viking Paradise ......"

When the business world was shaken by Tiancheng, and netizens were also stimulated by the 'alien civilization', the Internet changed its direction and returned to the VR world again.

Tiancheng Stone Light Machine has long been recognized by netizens as the most stable, domineering, and strongest server on the home planet, and there is no one.

In the past three years, although there has been a jam, there has never been a 'outage' incident.

What's more, this time it was hastily closed on the grounds of 'irresistible factors'.

There is no need to open your mind, netizens have connected 'Ceres', 'UFOs', and 'Australian Kangaroo Incident', and finally concluded that the Ceres civilization invaded the home planet.

In this way, all of this has an answer.

Netizens who firmly believe in this gathered in the Panda Guard-Tiancheng plate, Boss Aitege.

"MMP, this guy is really in the eyes of money, and Aite has to charge!"

"No charge, someone Aite you every day, are you annoyed?"

“......”

Long.

"Lao Ge, it's almost enough, in the past ten minutes, you have earned it, come out and answer the question!"

"Okay, here we go!"

"Huh, why is it 'Big Black'?"

"Uh...... Sorry, I used the wrong vest. ”

“......”

"Brothers, if you want to know anything, just ask. ”

"The people in the world in VR are really aliens?"

"Sorry, we are further confirming, and the relevant information will be shared as soon as the conclusion is reached.

However, in order to experiment, we are preparing to open another set of servers on September 28th, at which time, everyone can log back into the VR world and participate in the new exploration of the 'virtual home planet'.

It should be noted that if someone finds an 'unknown person', please be sure to lock them down through the interactive button and contact the VR guardian.

This helps us to further study the unknown, and it is also one of the means by which we humans come together to protect our own civilization. ”

"Lao Ge, so in the new VR world, it is also possible that they or them?"

"It's hard to say, our spacecraft has already gone to Ceres, and I also plan to transfer hundreds of millions of funds to increase investment in Tiancheng Aerospace Taibu, Daqin Bingfeng, Tianwei Group, etc., which have science and technology and armed forces.

I believe that everyone should not know that the annual investment of the mother star in the aerospace field is actually very small, and it is not even comparable to the military expenditure of a medium-sized region.

If we can concentrate on doing great things, I believe that with the massive amount of money and the joint efforts of countless scientists, we will definitely be able to protect the home planet!

Believe in Tiancheng, we can do it!"

"Lao Ge, listen to what you mean, it seems to represent...... Is there a possibility that we will have an interstellar war?"

"It's hard to say.

Because according to the principles of the Tiancheng universe, in fact, alien creatures, like us, are currently in the novice village and cannot get out of their respective local galaxy groups.

As for some unscientific events, or unexplained extraterrestrial events.

I'm sure it's all fake, and even if one case is true, it's just like the guys in the game who were born with kryptonite, and they just happened to pass by our novice village.

This kind of big guy doesn't care about us, and just wants to find a higher-level wild monster area.

Of course, we don't have to be disappointed, because the mother goddess Nuwa is a super VIP, and when we leave, we have prepared a big gift package and a 'super plug-in', and we will soon catch up with the kryptonite bosses. ”

"Lao Ge, I'm panicking now, don't talk nonsense. ”

"How can it be called nonsense, as I said in an interview with Tacheng before, it turns out that if we stay in the home planet to study the universe, we will never be able to fly out of the solar system, because this is a kind of cosmic rule.

It's like dividing the map into a novice village, a low-level monster area, an intermediate monster area, and a high-level monster area in the game......

The same is true of the universe.

Therefore, there is the first cosmic velocity, the second cosmic velocity, and the third cosmic velocity......

They correspond to the parent star, the solar system, the Milky Way, and the local group of galaxies......

If we want to reach our own galaxy group, the fourth universe, we must first develop the solar system and adapt to every planet environment in the solar system, and then develop the Milky Way and adapt to every planet environment in the galaxy.

Speaking of which, it has to be said that the mother goddess Nuwa is loving, and she has prepared for us, including the mother planet, nine celestial bodies with different environments to help us study the universe. (In 03 it was still nine planets, and in 06 it was removed Pluto)

It also includes numerous moons and dwarf planets.

It's like a rookie who has just established a game character and suddenly gets a super gift package from the GM.

Therefore, we must cherish these resources, and we must also make reasonable use of these resources as soon as possible.

So, don't worry about interstellar wars, because alien creatures are just like us, all staying in their respective novice villages, infinitely far away from us, and there will be no clash of civilizations at all, at least not in our generation.

And what we have to do now is to study hard and make progress every day!"

"Lao Ge, you may not believe it when you say it, just when you were just verbose, the previous VR world automatically opened. ”

"How is that possible?!"

Boss Ge hurriedly went offline.

Meanwhile.

Hundreds of millions of netizens have entered the VR world that should have been closed.

It's no surprise that I met those strange 'people'.

Thereinto.

A netizen passed by the school and saw an 'alien junior high school student' in class, and their teaching method was not a small blackboard, but a virtual AR, forming an image directly in front of him.

Moreover, the theory of the universe they learned is not the current popular dynamic map of the solar system of the parent star, or in other words, it is not the circle of the nine planets around the sun.

Rather, the sun led a group of little brothers who spiraled around him, circling around a nebula.

Among them is the Azure Star, which is its home planet.

"This ......"

The netizen uploaded a short video.

Soon, a vocational university lecturer commented: "That's correct, it's just that it's hard for our junior high school students to understand this cosmic form, so let's learn the sun-centered week form first." ”

"But, teacher, the 'gravitational force' of the universe they talk about is not gravitational force. ”

"It is also correct that in the universe, the so-called 'gravity' is just a kind of 'space-time bending', Tiancheng Secondary School Astronautics 02 Edition textbook, there are relevant explanations. ”

"No, what I used to see in textbooks was indeed gravity. ”

"No, you actually learned about centrifugal force before, but centrifugal force does not exist in the universe at all. You have to remember that the main cause of the celestial system is not gravity, but the curvature of space-time caused by mass. ”

“？？？”

"If you want to know more about it, you can sign up for Tiancheng Online School, or Tiancheng Technical Secondary School or Tiancheng Continuing Education, and the teachers there will help you correct the misconceptions left before. ”

“......”

Netizens who enter the world of VR are all instantly destroyed by the three views, and even overturn the previous cognition.

When I returned to the Panda Guardian Forum, I saw countless new 'popular science posts'......

"It's over, the alien civilization is too powerful!"

"Made, in terms of education, we are not at the same level at all!"

"Where's Lao Ge?"

.........

Ge Xiaotian was sitting in the Tacheng Aviation Department, looking through the server background.

The corners of Daoyi's mouth twitched, "Boss, I don't think it's a good thing to release all the scientific systems for teenagers who are in the education stage. ”

"Have you ever heard of a hundred schools of thought? If you always adhere to a scientific system, who can guarantee that it is correct? If multiple schools of thought are born, compete with each other, and learn from each other, you can merge more powerful 'disciplines', isn't this the strength of 'yours'?"

"Well, you have hanging, you're right. ”

"Let people learn and learn in the VR world first, and a week later, start the Western 11th Party. ”

"Okay, but boss, the 'heat pump' is about to be completed, and I guess it will trigger the upgrade conditions, can you go over and take a look?"

"The last building of the fifth-level mastermind?"

"If you don't miss anything, it should be, but this upgrade has nothing to do with the mastermind building, I suspect it is the control of capacity utilization. ”

"Let's go and see. ”
