In fact, spaceflight doesn't happen like the starry sky in the movie. In fact, the cosmic scale is too large, and no matter how fast the plane is, even if it is the speed of light, it is insignificant compared to the cosmic scale.

Of course, Long Xinsheng also knew a little bit about it, so he reacted quickly. Only now, the plane is flying straight towards the moon, opening out of the porthole, only the bright starry sky, and nothing else can be seen.

The plane accelerates slowly, because there is no air resistance in space, and theoretically, as long as the engine is kept running, the acceleration will increase indefinitely. Of course, after reaching a certain level, there will be another kind of resistance, a theoretical resistance—now it is only theoretical, and it has not yet been proven, that is, the resistance of space itself. The basis of the theory is the theory of relativity.

But for today's passengers, they are experiencing rare acceleration. For a short period of time, a healthy person is able to withstand three to five times the acceleration of the Earth's gravity; But only for a short time. Just like strenuous exercise, everyone can run a certain distance, and it is not a problem to grit their teeth and run up to three or five hundred meters; But if you want to run thousands of meters, you can only be a professional.

And that's it, acceleration in a short period of time can be counted as enjoyment, such as bungee jumping; However, a long period of time can cause a great burden on the body, especially the cerebrovascular system. Therefore, the master company has specially set up an alarm device, as long as anyone feels unwell, the acceleration will gradually decrease within a reasonable range, until the gravity is doubled. And in a gravity environment of double the body, the human body can maintain its best condition.

Long Xinsheng felt the gradually extremely extreme pressure on his body, which had exceeded three times the gravity, and when the plane took off on the ground, there was no such pressure. In the gravity environment, it is not like carrying a heavy load, as if every corner of the body is infused with mercury.

Five times the acceleration due to gravity!

Looking at the prompts on the screen, Long Xinsheng felt the pressure, although he usually pays more attention to sports, and after signing up, the master company also conducted simple training for flight personnel, but after all, the essence of the body is still weak, and the perennial city life makes Long Xinsheng even if he pays attention to maintenance, his body is also in a sub-healthy state.

It's just that it's a bit embarrassing to press the button, and it's a wonderful pleasure to have such a limit speed.

Fortunately, before Long Xinsheng could decide, someone had already pressed the button. Long Xinsheng turned his head to look at it, it was Qin Shifang, the person in charge of the Second Construction Group of Qingzhou Province, who was relatively close to the master company, after all, he was older, and he was about to pay for his life with 5 times gravity, and now his face was pale, and it was obvious that he had reached the limit.

Then, Long Xinsheng felt the plane shake slightly, and then the acceleration began to decrease slowly. In this case, once the acceleration is drastically reduced, it can directly cause the collapse of the cardiovascular system; Without professional training, it is directly murder. Fortunately, the master company is also experienced, and the acceleration is decreasing at a speed of 0.1 per minute, which is just enough to allow the body to adjust.

The acceleration gradually decreases until it is reduced to 0.8 times the force of gravity. At this time, Qin Shifang had fully recovered, and looked at the screen next to him with some fear.

With 0.8 times gravity, the aircraft has reached a speed of 22 km/s.

In just one moment, the speed of the plane was doubled! Sure enough, space is not the Earth's atmosphere. Not only Qin Shifang, but even the other fifteen people were watching. After all, it's a bit boring to look at the almost unchanged starry sky outside now.

After about five minutes, the plane began to accelerate again, but this time it only accelerated to 2 times the gravity, and there was no improvement, and everyone was a little stressed, but not so uncomfortable. Of course, the body still can't stand it for a long time, and there is no problem with monofilament for three or five hours.

The driver's majestic voice sounded: "Everyone, we are very fortunate that we are very close to Mars now, and you can observe Mars with a telescope. What a lucky journey. ”

"Mars!" Everyone was stunned for a moment, and then they began to observe with the delicate astronomical telescopes that they had prepared. For this space trip, everyone spent tens of thousands of yuan to buy that extremely delicate portable space telescope. After all, 1.5 billion yuan has been spent, so I don't care about tens of thousands of yuan.

As a person with a dream, Long Xinsheng spent millions of oceans to buy an optical and laser dual-purpose astronomical telescope, and the progress of science and technology has made such a delicate telescope a portable binocular, but the function is extremely powerful.

From space, Mars is indeed red at first glance, but a closer look reveals that the thin atmosphere, like Earth, is also blue. However, this is also a good explanation, because the ground is rich in iron, it is red; Dust in the air scatters light, and like the Earth, the sky is blue.

The potted surface of Mars made Long Xinsheng look at it with relish. The journey to the moon is reported by the master company for 3-5 hours, and the specific situation depends on the endurance of everyone's body. Therefore, now someone has started to sleep.

But...... There is always a discordant voice: I'm going to the bathroom!

The journey has been four hours now, and even on the ground, it has been dealt with in advance, and now most people have reached the limit.

"Wait a minute."

The plane began to slow down, and gradually, the gravitational acceleration disappeared. Of course, the speed of the aircraft has reached 30 km/s, almost 110,000 km/h. Even though the engine has stopped, the plane is still moving at high speed.

The gravitational acceleration all disappeared, and at that moment, Long Xinsheng felt that he was as light as a feather again.

"The toilet is at the rear of the cabin, please hold on to the handrails along the way, now the plane is traveling at 30 kilometers per second, please pay attention to safety."

In space, people and planes are now in a relatively static state, Long Xinsheng also felt a little uncomfortable, opened the seat belt, grabbed the handrail, and flew forward, a wonderful experience. With a slight push on your fingers, you can push yourself out of the way.

Awesome airplanes use air circulation, and excrement is discharged directly into space and becomes space junk. This is due to the huge load and low price of the master company's aircraft, which does not require everyone to drink the circulating filtered water with a strange smell - which, in other words, is really disgusting.

This space junk will soon fall into the sun, or other stars.

Twenty minutes later, the plane began to accelerate again, gradually exceeding 50 kilometers per second.

"Everyone, please note that we have reached the sky above the moon, and the next step will be to use the moon's gravity to slow down, pay attention to the seat belt, and count down 10 minutes to 9 minutes......"

The countdown ended, and gradually a huge centrifugal force acted on everyone, changing direction indefinitely, as the plane also flipped in space.

The Moon in space is not as beautiful as it is on Earth, just a gray and potholed world; And now, there are some artificial buildings dotted on it, which are fully automated mining bases in space. However, these things are very small, usually only 100 meters in size.

The sunrise on the Moon is not as spectacular as on Earth because there is no air to scatter. Only a blinding ball of light could be seen rising above the surface of the earth - not the moon's rotation, but an alternative sunrise caused by planes orbiting the moon.
