Suddenly.

It's so sudden.

Before the afterburner take-off of that space shuttle in the shape of a delta wing.

Country Z has never announced an early manned landing on the moon.

According to the established "three-step moon landing" plan, the first step is to first realize the "orbit" of the exploration satellite to the moon, which was successful 17 years ago in 20X7.

The second step is to "land", to realize the landing of unmanned probes on the surface of the moon, release a small lunar exploration rover, and walk on the surface of the moon...... This step was successful 11 years ago with the launch of Chang'e-3.

The third step is "return", launch a large unmanned probe, land on the surface of the moon, use robots or robotic arms to collect lunar soil, put it into the return capsule, and launch the return capsule carrying lunar soil back to Earth.

But the "orbiting", "falling", and "returning" here are nothing to do with human astronauts.

Even if it is returned with lunar soil, it is a "no one to the moon" operation.

The real "manned landing on the moon" was scheduled for 20X0 years later.

During the struggle for hegemony between the Soviet Union and the Soviet Union in the sixties of the last century, the manned lunar landing mission of 10 billion knives was carried out seven times in a row, and only the people of country M were so rich and capricious.

And the purchasing power of 10 billion dollars in the sixties of the last century, converted into the current yuan, is roughly equivalent to 300 billion.

Of course, the level of science and technology is rising, and the cost of space launch activities is decreasing.

If the manned lunar landing program is implemented at this stage, it will cost more than 100 billion yuan each time, and country Z can send a group of astronauts to the moon.

But the people of country Z don't do it, it's expensive, it's too expensive, and they pay hundreds of billions of dollars just to get back a few hundred kilograms of lunar soil from the moon, which is not cost-effective, and this deal is too cost-effective.

If it is known by some brick families, they will definitely criticize the "labor and money" and "face project".

Therefore, the "manned landing on the moon" has always been a plan that stays in words and has not been implemented on paper.

Unless the time is ripe, it is possible to implement the project.

But this time, the NASA of country Z suddenly built a "Feitian" space shuttle and suddenly announced a "manned moon landing" plan, which caught everyone off guard.

Is this fake news or amplification, and how credible is it? Is it true that astronauts from country Z can set foot on the surface of the moon?

Everyone's faces were full of doubt.

You know, it's only been 20X4 years now.

But it's true.

After the "Feitian" space shuttle entered outer space, it quickly connected with the "Tiangong-3" space station, which filled the "Feitian" with fuel and replenished some materials, and then the "Feitian" sped up, got rid of its orbit around the earth, and headed straight for the moon.

Live on TV.

An aerospace expert explained:

"We are 100% sure that the manned mission to the moon completed by the Space Shuttle Feitian will be successful."

"Generally speaking, using the traditional manned lunar landing method, we have to launch a large spacecraft weighing hundreds of tons to the moon, the composition of this spacecraft includes a lunar orbital module, a landing module and a return module, most of which carry fuel, astronauts can only be active on the lunar surface for two or three hours, carrying less than 100 kilograms of lunar soil back, but the cost is as high as two or three hundred billion."

"Such a high-cost moon landing, country Z really can't afford it, we can't afford to play such an expensive game."

"And now the reason why we dare to carry out the 'manned moon landing' is that we have found a way to save costs."

"That is, directly let the space shuttle 'Feitian' land on the surface of the moon, carry out scientific experiments, collect lunar soil, and then lift off vertically, turn around and return."

"It stands to reason that this way of landing on the moon is not possible, but we can do it!"

"Because the detonation engine carried by the 'Feitian' is more than five times more efficient than the rocket engine, the Feitian carries 10 tons of fuel, which is equivalent to 50 tons carried by ordinary spacecraft."

"In addition, the 'Feitian' carries the 'high-energy No. 1' battery with the highest energy density, and the large amount of electrical energy stored can be used as a power source for several 'Hall engines' at the tail of the Feitian."

"The Hall engine, also known as the 'ion engine', uses an electric field to accelerate the injection of particles at a speed of more than 100 km/s, which is the engine with the highest specific impulse, and can save more than 90% of the thrust medium compared with other engines."

"And Feitian carried the most efficient solar panels to charge the batteries in the space shuttle."

"During the Feitian journey to the moon alone, the electricity generated by the solar panels alone is equivalent to saving nearly a ton of fuel."

"It's the same with coming back."

"In the end, in the process of landing and taking off on the lunar surface, the vertical take-off and landing method was adopted, and the small engine at the bottom of the Feitian was used to achieve vertical landing and vertical take-off...... The Moon's gravity is only one-sixth that of Earth's, and it doesn't need much thrust for Feitian to take off. ”

"The combination of a variety of technologies, Feitian not only has enough fuel and materials to go to the moon, two astronauts can stay on the lunar surface for more than 12 hours, and transport back more than 1 ton of lunar rock and lunar soil, the total cost of landing on the moon does not exceed 1 billion yuan."

"So when the time was ripe for a manned landing on the moon, we decided to do it right away, and we were 100 percent sure."

Hear here.

The audience, who had a little scientific literacy, all nodded, I see!

30 hours later.

Under the gaze of billions of people around the world.

The spacecraft descended altitude, decelerated continuously, and finally landed steadily on the surface of the moon.

Opening the hatch, two astronauts from country Z stepped off the space shuttle and planted a bright red five-star red flag on the surface of the moon.

"It worked!"

"We made it to the moon!"

"Unbelievable, I can't even believe it's real?"

"Thousands of years of dreams of lunar exploration and moon landing have been realized so easily?"

The whole land of country Z was boiling, some people cheered, some people couldn't believe it, and more people burst into tears.

On the Internet, some netizens have not yet reacted.

"At the moment, I am not moved at all, only a look of confusion."

"yes, so suddenly! There was no warning at all, the manned moon landing was a success, and I didn't even have time to brew tears. ”

"I didn't have any psychological preparation, I didn't have time to brew feelings at all, and I felt very embarrassed."

"In a hurry, in a hurry, the foreplay was not done enough, and before I was fully lubricated, I boarded for a fast month, so how did I reach the climax?"

"Poof~! Dude, I've only heard of fast shots, never of fast moonshots. ”

"Huh, Ascend to the Moon? This description is quite apt, my brother is a talent! ”

So under the spread and spoofs of countless netizens, this significant, serious and tense moon landing operation of country Z was called "a fast moon landing" by the majority of netizens.

But for the people of country M on the other side of the Pacific.

Country Z suddenly landed on the moon successfully.

Watching the live TV broadcast, the astronauts of country Z were playing and jumping on the surface of the moon, and all the people of country M were stunned at the same time.

It was also a huge shock to the collective.
