Zhang Guoqing, who was standing in front of an international aerospace aircraft airport, looked at the aerospace plane that had just taken off overhead, turned around and said to the young man holding a suitcase who followed him:

"Yangyang, you've been with me for five months, do you regret retiring from the army and following me, an old man?"

"You are the one who made me see life other than the army, and I don't regret it!

I'm afraid that your grandson will be angry with you when he sees me discharged from the army. Pen & Fun & Pavilion www.biquge.info

Afraid that he thinks I robbed his grandfather. ”

Li Yang shrugged his shoulders and said helplessly.

"This world has never regretted medicine, and if you choose to follow in my footsteps, you must continue to move forward.

You have to know that as soon as you walk through the doors of this airport, you will not be the same person you used to be. ”

Zhang Guoqing patted Li Yang's shoulder and said.

"I like the name Zhang Yang very much, I'm your grandson!"

Li Yang smiled and took Zhang Guoqing's hand and stepped on the first step, not at all like the eighty-year-old man in Zhang Jun's mouth.

"What a good grandson!"

“……”

With the progress of science and technology, the International Space Station in the sky has been retired with the United Nations space station, and the only one in the space station of Huaxia has developed to more than 30, which has been completed in a hundred years, all of which are energy changes.

Since the advent of nuclear fusion power stations a few decades ago, the fate of the planet has changed dramatically.

From the beginning of only astronauts, to a hundred years later, the International Space Station was commercialized, and tens of thousands of people travel and live on the ISS every year.

Even so, the space aircraft ISS travel is still very expensive, in addition to the local tyrants are pure tourist vacation clothes, many small countries of astronauts will also be willing to pay for the high cost.

There is also a group of people who go to the International Space Station for treatment, especially for people with low height complex, and it has always been their dream to be tall.

Compared with the high cost of surgery to forcibly break the leg to grow taller, living in space can grow taller, and the cost of space travel is no longer a high cost for them.

And then there's the people who work on the International Space Station.

Compared to those who travel to the International Space Station, some scientists, elites, and local tyrants fly to the moon in high-efficiency aerospace aircraft.

"The Moon is the only natural satellite of the Earth, and like the Earth, it does not emit light, but only reflects sunlight.

The Moon revolves around the Earth, and there is a revolution around the Sun along with the Earth.

The moon's autobiographical cycle is the same as its orbit around the earth, so the moon always faces us in the same way, and it was not until the era of interstellar navigation that we humans first saw the beauty of its back in the photographs taken by spaceships.

Through laser ranging, humans know that the distance between the moon and the earth is 384,401 km.

The average diameter of the Moon is 3474. 8km。

The gravitational acceleration on the surface of the Moon is smaller than that of the Earth, only one-sixth of the gravitational acceleration on the Earth's surface, that is, the weight of a person on the Moon is only one-sixth that of the Earth.

A slight jump on the surface of the moon will take you into the air, and even the high jump champion on Earth will be in the dust.

We used a telescope to see that some of the dark areas on the lunar surface were actually lunar seas.

There is no water in the Moon Sea, but it is a vast plain.

Most of the Moon Sea is on the front side of the Moon, and the largest is called the Storm Ocean.

There are very few lunar seas to the north of the moon.

High in the area of the Moon Sea, scientists became Moon Land.

There is also a series of precipitous Goldman Sachs III on the lunar surface, with the highest peak reaching 9,000 meters, which is higher than Mount Everest on Earth.

The moon is covered with craters, large and small.

The famous Copernicus craters and the valley craters all have bright radiation questions, which extend outward from the center for 1,800 kilometers.

There are also large fissures on the surface of the moon that stretch for hundreds of kilometers and are several kilometers to tens of kilometers wide, like the Grand Canyon on Earth.

With space exploration, the far and frontal sides of the Moon vary greatly.

The northern lunar sea area is less, and there are more craters, and the surface is uneven and undulating.

The back York is thicker than the front, reaching 150 kilometers at its thickest point, while the front is only about 60 kilometers away.

There is almost no atmosphere on the Moon, only very small amounts of gases, the main components of which are helium and argon.

Since there is no atmosphere, there is no liquid water on the Moon, because the temperature of the Moon is as high as one hundred and twenty-seven degrees Celsius during the day and becomes minus one hundred and eighty-three degrees at night.

However, there is a large amount of ice water in the two-stage region of the moon, and human beings can exploit the lunar water source and use the moon as an intermediate station for more distant space navigation and exploration.

From the very beginning of the establishment of a space station on the moon, to the space platform, orbital maneuvering vehicles and manned maneuvering vehicles, to the current establishment of a lunar base.

There are now only five countries that can establish bases on the moon.

The stations that have been divided by various countries now have cities on the moon that belong to each country.

Compared with life on Earth, going to the moon for a vacation has become the most extravagant expense.

The aerospace plane that Zhang Jun and Li Yang are going to take is to fly in space with an officially approved aerospace plane powered by antimatter, and the destination is the moon.

From the moment the aerospace plane was born, it was a space transportation system that was researched and developed by the space powers more than 100 years ago.

It can be said that the aerospace plane is a manned spacecraft that integrates spaceflight, aircraft, space carriers, and spacecraft, and after so many years of research, it can fly back and forth hundreds of flights.

Compared with the aerospace plane more than 100 years ago, it ran from the airport to takeoff, flew in the atmosphere at hypersonic speed, went directly into space, became a spacecraft, and when landing, it could land on the airfield like an airplane.

Since the advent of antimatter-related clean energy engine systems, aerospace aircraft have seen qualitative overflights, almost all of which are flying at speeds close to the speed of light.

Theoretically, it takes only 1.28 seconds to get from Earth to the Moon.

Due to the initial velocity and the cushioning at the time of landing, the time it actually takes to reach the moon from the Earth and the space plane together becomes ten minutes.

Unlike the Earth, which has the protection of the atmosphere, many meteorites have been filtered when they enter the atmosphere, but the Moon is a crater full of holes.

These craters are often also inhabited by cities on the Moon, and from the moment they step aboard the spaceplane, each of them must wear a spacesuit made of nanocoats.

Compared with the spacesuit of the 21st Historical Record, the spacesuit of the 22nd is more close-fitting and lighter, and the helmet is just a transparent oxygen mask made of special materials.

The so-called aerospace aircraft airport is also extremely tall and noble, by opening the huge transparent window, Zhang Guoqing and their aerospace plane at the moment of landing, the window is also closed for the first time.

When they walked out of the airport, they lived on the moon in spacesuits on a leased basis...... (To be continued.) )
