Time does not depend on human will; although Yang Qinyun felt very unhappy, time still moved forward firmly! The day of glory is rapidly approaching!
Early in the morning on May 1st, before dawn, Yang Qinyun got up! Cheers, cheers. Also, because the hotel said today that it is a holiday, if the guest needs help with anything - please postpone it, or you can do it yourself. The key to the hotel's warehouse, kitchen, etc. is hung on it; of course, As compensation, we don’t need any money today, well, we don’t need any money tomorrow or the next two days, because we also have a holiday tomorrow and the next two days!
Looking at the empty hotel, with not a single service person to look at, and the warehouse door just hanging open with the key, Yang Qinyun was more shocked than smiling bitterly. But it makes the people of the Republic have to think!
Keeping the door open at night and not picking up lost things on the road were once just exaggerated metaphors and beautiful longings left in ancient history books, but on Venus, they have been realized. But to be honest, seeing the waiters with guns on their waists is quite heartbreaking for people from Earth! However, Yang Qinyun was not prepared to miss today's grand occasion.
As the imperial capital, Longxing City was huge, and the central square was said to be a holding square that could accommodate one million people. The only pity is that the empire has not held any military parades and so on since its establishment. However, maybe people don’t bother to do this at all! But now such a huge square is already crowded.
The sun has just come out, and the square is already crowded with people selling snacks and having fun. Occasionally, you can see panicked squirrels running through the crowd. People consciously park their vehicles on the outside and enter the square on foot. In the center of the square, there are several erected antennas, which are said to be used for positioning.
Compared with other cities, the live broadcast here in the Imperial Capital, according to the news, will be directly projected from space, except for the problem of scale. The rest is basically guaranteed to be 100% true. Projecting directly from space to the ground is a technology that, to be honest, is the first time I have heard of it. Yang Qinyun was shocked. Fortunately, it is said that this is only the latest technology developed, and this is also the first time it has been used. But this still surprises people on earth too much.
Time gradually passed, from the scorching sun in the sky to the setting sun, but the crowds grew larger and larger, so much so that they could hardly move.
When the sun goes down, a gray-white color appears in the sky, just like the startup screen. It's just that this screen is a bit big, with a radius of more than a thousand meters, and it's also hanging thousands of meters in the air. But even at an altitude of thousands of meters. It still seems to be hundreds of meters in size. If you use one word to describe it, it is simply: covering the sky with one hand! More importantly, this projection of the Imperial Capital was projected directly from space!
Maybe. The only flaw is that there is no sound! Also, if it is projected directly from space, there will be no problem with the light, but there will be a problem with the sound. But it doesn’t matter, you can’t spread it directly, you can do it indirectly. Staff on the ground have been debugging the sound in every corner of the square.
As the last trace of light in the sky disappeared. Before the starry sky appeared, the huge projection flickered a few times, and then a huge spaceship image appeared!
That is the huge Clairvoyance Space Factory, 1,700 meters long. But now, even if the projection is only one thousand meters away, the shock of the spacecraft entering the atmosphere is still there. It also made Yang Qinyun breathless.
It seems as if a real spaceship is coming from a thousand meters in the sky. If you don't know in advance that this is just projection technology, it will definitely make people who don't know why panic. It’s simply blocking out the sky! Then, the camera started to zoom in quickly. When we got closer, we could even see a 100-meter-sized glass canopy, which reflected the sun's shadow and faint streamer.
The screen switched and entered the glass cabin cover. Yang Qinyun saw the working environment of the Imperial scientists in space. They were lying, standing or leaning. Everyone had their own space for activities and various expressions. Anyway, there is no gravity, so everyone can play however they want.
However, as the picture got closer, Zhang Wenliang's figure gradually appeared. Zhang Wenliang's clothes are still simple, and if you look closely, you will even find that they are a little starchy; Dongfang Xiaoyun next to him is still beautiful, and he looks like a fairy in white clothes. Sharp-eyed people even discovered that Zhang Wenliang’s clothes were from last year!
"Hello, citizens of the empire." Zhang Wenliang said with a smile, but the direct projection speed was faster. After saying hello, the sound was transmitted from the speakers on the ground.
"Long live your Majesty..." I don't know who started it first, but people almost sent out blessings from their hearts. This is not pretentious, but a real cry from the heart!
"Sorry, due to various reasons, my information transmission here is one-way, and I cannot see or hear the voices of citizens. Please listen to what I have to say.
First of all, while we are all taking a break, our great and lovely scientists are working overtime. For this, let us express our gratitude to them. It is them who make us live the life we have now.
In addition, there is the problem of the launch of the starry sky cannon. Someone told me before that such an advanced experiment might fail. If it were broadcast live, failure would be a blow to the majesty of the empire. It is best to render the successful plot and then release it after success.
But I denied it. I think, whether it is success or failure, this time is our first step into the universe. Success is gratifying, but we continue to work hard if we fail. We are not afraid of failure, but we are too afraid to face failure!
Nothing never fails, not even a star cannon that has been checked a thousand times can avoid this problem. All I can say is that even failure is proof of our unremitting efforts; the worst we can do is start all over again! If we can do the first one, we can do the second one! The Clairvoyance Space Factory is always on standby!
Also, the fact that the empire has come so far is not the result of the efforts of one or two people, but the result of the joint efforts of everyone. Therefore, I think this historically significant moment not only belongs to the empire and scientists, but also to every citizen!
We like success, but we are not afraid of failure! In half an hour, we will usher in the pinnacle moment of human history. Let us look forward to it and pay attention to this miracle that belongs to all of us! ”
"Long live... long live..." people shouted wildly, with passion and fighting spirit shining in their eyes. Yes, even if we fail, it is still our most precious wealth! To go into space, you have to be prepared to fail. therefore. We are not afraid of failure! We refuse to be afraid of failure!
Half an hour is not long, and everyone also saw the busy figures of scientists during this half hour. Under the spotlight, they remained meticulous and carried out final calculations and inspections.
Ding dong... countdown begins: 10 minutes...
The camera starts to zoom out. The panoramic view of the tens of thousands of kilometers of starry sky cannon is displayed in front of everyone, and there are even a few close-up shots. This is a real monster!
There is no sound in the video because it is impossible to transmit sound in space. However, as the saying goes, silence is better than sound. For three minutes, the video kept switching, and everyone saw the complete appearance of this surreal product. One hundred thousand pairs of blades - photovoltaic cells, surrounding cables, smooth guide rails that reflect the starry sky, some unknown complex components, etc.
Suddenly, a small space shuttle appeared, but this space shuttle was carrying a disproportionately huge object! Above the huge robot hand, grabbing something that is 50 meters long but only 50 centimeters thick, there is a two-meter-long metal head that looks like blue spray paint. The rest is a golden tail.
But soon, there was a commentator explaining. His voice was a little old, and his Mandarin was not very standard. To be precise, he had a strong local accent - obviously. It was a scientist explaining.
"What you are seeing now is the space probe that is about to be sent to space. Because it uses a large amount of lightweight and high-strength new materials, its mass is only 200 kilograms, and it has a small plutonium (bu) nuclear reactor built in. This is The most mature technology at present. This small nuclear reactor can operate stably for fifty years, with a power of 10 kilowatt hours per hour, which will be enough to complete our goal this time. .
in addition. The body of the space probe is the blue metal cabin in front, which is fifty centimeters in diameter and two meters in length. It contains a nuclear reactor and weighs a total of 87 kilograms. And the rest of the tail. It is a solar sail weighing 113 kilograms.
It is known that the speed of light is the fastest and constant in the universe. However, if the object moves differently, a red shift or blue shift will occur to compensate for the speed of light. Among them, red shift represents a decrease in energy - objects move in the same direction as the speed of light, and blue shift represents an increase in energy - objects move relative to the speed of light.
The principle of a solar sail is the same as that of a wind sail, except that the sail uses natural wind. Solar sails use sunlight. Wind has pressure; sunshine also has pressure!
The intensity of sunlight in Earth orbit is about 4.8 kilograms of force per 10,000 square meters. On Venus, because the light is increased by one-tenth, every 10,000 square meters of natural light can produce about 5.3 kilograms of thrust.
In order to add this power, we use a large number of reflectors to capture sunlight. The densely packed reflectors in space are prepared for this purpose. We can gather a hundred thousand times more light. Of course, given the solar sail's ability to withstand high temperatures, we'll actually be using a thousand times more light. In other words, the combined light pressure is approximately 5.3 tons of thrust per 10,000 square meters.
This time, the effective area of the solar sail is 7,000 square meters, and it will get an effective thrust of about 3.7 tons; of course, this refers to a stationary state. Considering that as the detector accelerates, the light will produce a red shift, further reducing the energy, the efficiency will be about 75%, and the final thrust will be about 2.7 tons. In the design, we will accelerate the detector to a predetermined speed of 0.7 times. The specific amount depends on the actual situation. Because according to the mass-energy formula, it can be known that the greater the speed, the greater the mass; and as the speed increases, the time of the object will also change. We have never tried to build something so fast, and the specific physical state is not particularly clear. But one thing is certain, that is, the target of this exploration will be the star T in the Cetus constellation 12 light-years away. Here, based on our current astronomical observations, it has been basically determined that there is a planet suitable for human settlement, and It is very possible that there is life. Okay, everyone, please watch carefully what happens next. Let me remind you, because the speed is too fast, it only takes about 0.4 seconds from the start of the detector to the time it is sent! This will be the first time that everyone intuitively feels the speed of the interstellar era. From today on, the unit of speed in the interstellar era will be the speed of light. A few tenths of the speed of light is calculated in this way, instead of the calculation unit of kilometers and so on. ”
It only takes 0.4 seconds to cross a distance of 10,000 kilometers! This is an unimaginable number! Yang Qinyun felt that his brain could no longer change. 0.4 seconds, speed increased to 0.15 times the speed of light! Looks very powerful! No wonder it is said that the Star Cannon is the representative of the empire’s most advanced technology! It seems to be really advanced!
The countdown ended quickly, and the 100-meter-long detector was placed into the entrance of the guide rail and gently slid into the starting position. Then light blue light waves flashed, which was a super strong magnetic field and a large number of charged particles!
One hundred thousand pairs of wings have been fully opened, and thousands of plasma engines have begun to work, slowly accelerating forward with the guide rails. But this is for the upcoming shooting. Accelerating a 200 kilogram object to 0.15 times the speed of light in 0.4 seconds will produce a huge unimaginable reaction force. And these plasma engines are meant to balance these reaction forces.
Ding dong...the countdown has entered 10 seconds! Everyone became nervous.
3…2…1…
Yang Qinyun was equally nervous. Although this was not the technology of the Republic, we all belonged to the same nation!
0! ! !
In an instant, only electric light flashed, red, blue, purple, and invisible colors, all arcs of electricity, instantly covering the entire starry sky cannon. At that moment, the starry sky cannon seemed to transform into the God of Thunder! A divine thunder pillar!
At the same time, a light blue aperture instantly appeared at the tail, with a diameter of a hundred meters, and then quickly pushed forward and expanded rapidly. It was a violently fluctuating electromagnetic field!
0.4 seconds!
As if in an instant, before the countdown '0' disappeared, an object wrapped in light blue electric light was ejected from the cannon in the starry sky and rushed into space in an instant. In an instant, it was out of sight. Even if the starry sky is projected here, you can only see a point of light that quickly disappears and merges into the bright starry sky, never to be seen again.
It can be said that by now, the audience on the ground has watched the entire video - a wonderful video of only 0.4 seconds! Live broadcast!
In fact, in space, it is at this time that scientists have entered into truly intense work!
