Super technology leader

Flying to the universe, vast and boundless.

The universe is not only vast but also silent to human ears.

Here, you can't hear the noisy sounds of the ground, nor rows of barrages, only constantly running spacecraft.

The International Space Station flew by, the Tiangong Space Station flew by, the Starry Sky Inn docked with the orbital shuttle flew by, and the inflatable space station under renovation also flew by.

Originally, humans didn't have any Earth orbit space station plans in the near future, only commercial space station plans, which would be at least a few months later. But now, a space station core module flew over immediately, docking with a manned spacecraft slightly smaller than itself.

However, this spacecraft is not an Earth orbit space station, but a lunar orbit space station. It's not even a specially launched lunar space station project, but a lunar space station built along the way while conducting a manned lunar landing mission.

Watching the combination of the new manned spacecraft and the lunar orbit core module circle the Earth's orbit, all the projects underwent self-inspection, and seeing a row of green checkmarks, the Far Voyage super-heavy rocket ignited and took off.

The upgraded Long March 9 rocket has a lunar orbit transport capacity of nearly 60 tons, and it is easy to transport the new manned spacecraft and lunar orbit core module combination weighing less than 50 tons in recovery mode.

The Far Voyage super-heavy rocket is not as capable, its lunar orbit transport capacity is only 45 tons, and it can only send the Benyue spacecraft weighing just over 40 tons.

The orbital docking was very smooth. Tianxia's automatic docking technology has always been very clever. Even with the addition of the Pathfinder now, because of the use of unified standards, the synchronization rate between the two sides can reach 100%.

Even with the addition of the Pathfinder, this "100%" purity is higher, and the docking process is simpler and faster.

When the docking device of the lunar orbit core module captured the docking device of the Benyue spacecraft, the two sides locked and jammed, then slowly approached and adhered, and finally measured that the connection was airtight and seamless, and would not cause pressure loss and air leakage, the docking procedure was completed.

[Docking successful!]

When this sign appeared on the screen, the four astronauts on the manned spacecraft breathed a sigh of relief.

The four lunar landing astronauts who performed this mission were all carefully selected elite astronauts, specially formed and trained for this lunar landing mission, and the training program was more than the American lunar landing astronaut program back then, after all, they were going to stay there for a long time, not just come back in two days.

Cheng Dong is the mission commander this time. He is the second batch of astronauts in Tianxia and has performed a station mission in a space laboratory. The reason why he was appointed as the commander of this lunar landing mission is because of his age.

He is 43 years old this year, which is the golden age for astronauts. Experience, qualifications, physical condition, etc., are all very suitable.

After all, the age of the first batch of astronauts is generally close to 60 years old. It can't be said that they can't go into space, but most of them have already switched to teaching or administrative work, and some have retired due to physical reasons.

This time, they are going to the moon, which is far from the protection of the Earth's magnetic field, and it has little magnetic field protection ability itself, so the impact on the human body is much greater than in near-Earth space. The first batch of astronauts who are close to 60 years old are really not suitable for performing the task.

The deputy commander is a female astronaut, who is the same as Cheng Dong, is the second batch of astronauts, and is also 43 years old. She has participated in manned space missions and has rich spaceflight experience.

The main and deputy commanders are both astronauts from the Air Force, and are the second batch of astronauts. The remaining two are not from the Air Force, they belong to the more specialized third batch of astronauts.

Peng Zizhen is 36 years old this year. Before being selected into the third batch of astronauts, he was a geologist. The purpose of letting him participate in this lunar landing mission is quite clear.

Whether it is studying the moon itself, studying the mineral resources around the landing site, or clarifying the reserves of water ice, etc., it will be useful.

The last one, Tong Anfu, is the youngest of the four, only 34 years old, and is a mechanical engineer.

This lunar landing mission is different from any previous one. They will stay on the moon for a long time. The initial plan is two months, and then start to rotate.

His task, in addition to the daily maintenance of the Moon Palace II survival cabin and the Benyue spacecraft, there is also a lot of modification work.

Last time, Moon Palace II brought eight lunar rovers up, which can be remotely controlled by the ground, or can autonomously detect according to mission objectives. They weigh 500 kilograms and are used to find water and explore the moon.

Now that the astronauts are here, the astronauts can't rely on jumping to travel, that's too slow, so they turned their attention to these lunar rovers.

As long as some modifications are made, they can be turned into buses and trucks, which can be used to carry people and goods.

When these lunar rovers autonomously perform tasks, the walking speed is calculated in centimeters, when they are controlled by ground personnel, they are calculated in meters, and when they are actually driven by people, they can be calculated according to the speed of Earth vehicles.

Of course, don't expect them to be able to speed up to hundreds of kilometers per hour. With that little gravity on the moon, even if highways are built, it is impossible to speed up to that speed.

It is easy to drift if it is a little faster, and it will overturn if it drifts.

Road construction is definitely necessary. The astronauts from Tianxia have gone up, and they will not allow the roads they walk on every day to be uneven.

At least a road must be built between the landing site and the water ice mine.

The four of them will not stay in the lunar orbit space station. Everyone will land on the moon. The lunar orbit space station is the task of the next section of the space station module and the stationed astronauts.

The four astronauts, each has their own full-time job, and each needs to complete a lot of cross-work.

There is no way, it seems that there are many lunar landing astronauts, twice as many as the previous single lunar landing record, but compared to what they have to do, it is far from enough.

Fortunately, more lunar surface modules will land later, providing a safe place to live and work for more astronauts in the future.

The latest novels are first published on Liǔ 9 Shū Bā!

After Cheng Dong reported the mission and said a few words to the audience watching the live broadcast all over the world, the spacecraft combination adjusted its attitude, the manned spacecraft ignited, and carried them to the moon.

The excitement on Earth has nothing to do with them. Except for interacting with netizens a few times before departure, the rest of the time is in contact with the ground control center.

After completely entering orbit and the manned spacecraft no longer accelerating, they can finally get out of their seats and move around.

At the same time, they have to go through the gate to see the lunar orbit core module and the Benyue spacecraft.

Especially the Benyue spacecraft, they have trained in the phantom space, but that thing is virtual after all, not the equipment they will officially ride when they land on the moon.

"Okay, let's start, first check the items that need to be checked."

After opening the gate between the manned spacecraft and the lunar orbit core module, Cheng Dong floated in first.

"Understood." The other three replied.

Because of the emergence of the phantom space, coupled with the full cooperation of the Space Administration and the Pathfinder, they can do a lot of training in the phantom space, and it is simulated weightlessness training, so they are now not only clear about every corner of the lunar orbit core module, this state of weightlessness has not caused much impact on them.

It stands to reason that the Benyue spacecraft is similar, not to mention training, they have dismantled this spacecraft three times in the phantom space, so naturally they are familiar with it.

But when they checked the core module, opened the hatch and entered the cockpit of the Benyue spacecraft, and continued to check smoothly to the exit, and saw the extravehicular spacesuits placed on both sides, they realized that something was wrong.

"Ah, this..."

"Captain, this is different from the extravehicular spacesuit we used for training?"

"Captain, is the extravehicular spacesuit like this?"

"Captain, are you sure this is a spacesuit, not... power armor?"

The four astronauts were stunned, because the "spacesuit" in front of them was a bit strange. The color was right, the classic spacesuit white, but the outside was not covered with the fabric of a regular spacesuit, without the classic fabric wrinkles, but pieces of hard shell.

Of course, if you say it is plate armor, it may be more appropriate.
