The Rise Of Space Technology

"Can you tell us about your current situation?"

"The acceleration is over, and the Houyi is in inertial flight. You can freely move on the Houyi for 2 hours. After 2 hours, please return to your seats."

"When any spacecraft is flying in the universe, it will basically rely on inertia to fly, because relying on inertial flight, the energy it consumes is 0."

The 'Houyi' continued to accelerate, and it was getting farther and farther away from the earth.

With the gradual shutdown of the engine on the Houyi, the Houyi still flew towards the moon at a terrifying speed of 120 times the speed of sound, and the vibration on the spacecraft disappeared all at once.

30 times the speed of sound~

"Many people have never been to space and have not undergone any training. Liu Yuan, the boss of Xinghai Technology, is also there. They have considered all aspects."

"From here we can also know the vastness of the universe."

"If this speed is put on the earth, it is really terrible. At 100 times the speed of sound, it does not take a few minutes to go from our northernmost Mohe to our southernmost Nansha."

In the live broadcast room of the TV station, this manned moon landing is being broadcast in real time.

The three foreigners, Katerina, Rogowski, and Bassong, are also conducting live broadcasts at this moment. They can also contact the ground in real time and send back their thoughts on the Houyi. .

"In addition, the reason why Houyi will not accelerate after reaching this speed is to save fuel. We all know Einstein's mass-energy formula. To achieve a faster speed, it needs to consume more energy."

The host thought about it and asked.

70 times the speed of sound~

Closer to the moon, farther from the earth.

"It's just beginning to come out now. In the future, it still has the possibility of infinite development. Maybe in the future, it is possible for our spacecraft to reach a thousand times the speed of sound, ten thousand times the speed of sound, and even calculate the speed at the speed of light in the future. , only when we reach a certain speed can we truly be qualified to look up at the stars and the universe."

"After the accelerated process is over, we will have about two hours for everyone to move freely."

The vibration and oppression caused by the acceleration just made everyone very uncomfortable. Now that the engine is turned off all of a sudden, there is no vibration anymore, and everyone can breathe a sigh of relief.

40 times the speed of sound~

"The distance between the earth and the moon is 380,000 kilometers, which is the shortest and shortest distance in the universe, but even with the Houyi at the speed of 100 sound, it will take more than 3 hours to arrive."

During the half-hour acceleration process, the speed of the 'Houyi' was also fully opened, and finally stopped accelerating when it reached 120 times the speed of sound.

"So it will not continue to accelerate. The fuel consumption is very large, but the speed increase is very limited. In addition, when it is about to reach the moon, it needs to decelerate, and it also needs to consume a lot of energy."

"The so-called inertial flight is a term exclusively used in astronomy. In theory, in a vacuum environment, the motion will always maintain its original state."

"Gentlemen and Ladies~"

The antigravity engine and rocket engine on the Houyi began to start, and the strong thrust pushed the Houyi to escape the earth's gravity and fly towards the moon.

"In two hours, we are about to arrive at the moon. Before arriving, we also need to go through a deceleration process that lasts for half an hour, so everyone needs to go back to their seats and fasten their seat belts. ensure your own safety.”

"It's just in space, you can experience this feeling all the time, but when you get used to it, it's nothing, and in the sky you will feel very relaxed, and your body will not have that sense of gravity, I I think if a fat man came into space, it would definitely be very comfortable."

"Why should Houyi shut down the engine when it accelerates to 120 times the speed of sound, and then rely on inertial flight to go to the moon?"

"At the predetermined speed, turn off the engine and enter the coasting mode!"

Soon, with the sound of an alarm sounding, everyone only felt a vibration from the Houyi, and suddenly a strong feeling of pushing back came, pressing everyone on the air seat.

"Actually, it is necessary to distinguish between the two concepts of speed and acceleration. The so-called acceleration refers to the change of speed in a unit of time, which causes huge pressure on astronauts. Speed ​​is not the key. The real key is acceleration, that is, in the unit. How much the speed suddenly increases or decreases in time will create a huge pressure.”

"At present, the Houyi is in a stage of orbiting the earth, and everyone can see the scenery outside the window beside me, this is the scenery in space, we can see the earth, and now we are facing exactly the Eastern Hemisphere, from We can clearly see Asia from space."

"When the speed is getting faster and faster, the energy it consumes will increase geometrically for each increase in speed, so in the process of flying, it is necessary to calculate a suitable speed, which not only ensures the speed but also can maximize the speed. Possible fuel savings, 120 times the speed of sound is the most suitable speed for Houyi!"

100 times the speed of sound~

Qian Xia is also experiencing the feeling of being in space, and she is also constantly answering questions from the audience in the live broadcast room.

120 times the speed of sound~

The reason why the live broadcast method can rise is entirely because it is highly interactive. It can see various comments from other people, express one's own opinions, and interact with the anchor.

In the pilot and control cabins, Liu Yuan looked at the huge monitor, which clearly displayed the relevant information of the Houyi. It was originally flying around the earth, and at the moment when it flew to the farthest apogee from the earth.

"Yes, what Professor Zhu said makes sense."

"Professor Zhu, the speed of Houyi is nearly 100 times the speed of sound. Isn't this speed too fast?"

"..."

"Okay, thank you Professor Zhu and Professor Li for answering some questions for us,

PS: Cough, everyone, don’t worry about the problem of this speed being too fast~

"But in space, because it is a vacuum environment and is not affected by any external force, it can fly by inertia."

"Houyi is a spacecraft, which is equipped with four super-large anti-gravity engines. Anti-gravity technology is the technology that scientists have identified as being used in the era of interstellar space."

"Professor Zhu, what is inertial flight?"

"Good host~"

"During this process, please fasten your seat belts and sit in your own position without any movement."

"Jingya, hello~"

"This is completely different on Earth, where everything is affected by gravity and air resistance, so the distance of inertial flight is very limited."

"Although the speed of Houyi is very fast, it is very stable throughout the acceleration process, and its acceleration is not large, so it will not cause too much pressure on the passengers in Houyi, which is why Xinghai Technology The side can confidently bring a lot of scientists, engineers and news media reporters.”

"Boom~" "Boom~"

"Okay, host, I'm in the cabin of the Houyi. You can see that all around me are news reporters from various TV stations."

Of course, everyone was talking non-stop, and when various live broadcasts were being carried out, the broadcast sounded, and suddenly these people hurriedly sat down on their seats and fastened their seat belts.

"Hello host~"

"Houyi is about to leave the earth's orbit and fly to the moon. During the flight, Houyi will continue to accelerate for nearly half an hour."

However, this acceleration is actually not large, and normal human bodies can easily withstand it. Compared with the daily training of astronauts, it is simply pediatric.

"When any object is flying, as long as the force is not re-applied to it, the speed of the entire flight process will continue to decrease, and the flight trajectory will continue to fall toward the ground."

"However, in the interstellar universe, this speed can only be said to be a very slow speed. The speed of light is 880,000 times the speed of sound, but even if we fly at the speed of light, our Earth will reach the nearest other planetary system. , that is, the Centaurus galaxy also needs 4.3 light-years."

"I think there was a little panic at first, just like the momentary feeling of weightlessness when we suddenly landed on a plane or a roller coaster."

"How does it feel to be weightless?"

"That is to say, after Houyi accelerates to 120 times the speed of sound, in theory, it can fly at this speed forever to the end of the universe."

With the sound of the broadcast again, everyone on the Houyi couldn't help but breathe a sigh of relief.

"However, at such a fast speed, can the astronauts, scientists and engineers in Houyi bear it?"

"..."

At the same time, you can see the speed display, the speed of Houyi began to soar rapidly, and everyone on the Houyi was pressed on the seat by this acceleration.

The host also finds time and opportunity to ask questions to the invited experts and scholars during the boring time, so that everyone can better understand the whole process.

The news media reporters in the cabin also began to be busy again, gushing about the feeling of the just acceleration process, and at the same time, they did not forget to compare the moon and the earth.

The moon looks bigger in the field of view, and the earth looks smaller in the field of view.

With the success of the connection, the screen of the TV station also changed, and soon it was switched to the cabin of Houyi, where Li Jingya was.
