As Artemis' astronauts returned to their spacious cabin to lie down dreamily as they toured the Moon, feasted on the magical Oriental cuisine, and partyed, they finally understood why Dr. Anna had made that tweet.

Compared with Artemis's "cramped", "backward", "messy", and "hard", the configuration of the Invitation Moon can indeed be regarded as a cruise-level scientific research ship - except that there is no independent toilet and bathroom.

Even if it is a public toilet and bathroom, the bathroom conditions of the invitation moon are also very good, although it is a public toilet, but it can be used to enjoy a toilet and bathroom for every four people.

Therefore, for the first time in two months, the crew of Artemis "washed" in a real sense.

……

"Joseph, are you sure you want to stay?"

In the bow command room, Captain Yang, Professor Huo Liang, Joseph and other three people sat at a rectangular "glass" table, and one of them was chatting with a cup of tea.

Joseph took a sip of his coffee and nodded slightly: "We still have to drive the spacecraft back into orbit." ”

This time, the three of them really had to stay for one more day before taking off, and then they had to go into orbit with the ISS for orbit checks, and then wait until the launch spacecraft on Earth brought repair parts to complete the repairs, and finally they could return.

Professor Huo Liang said with a smile: "Then let's take off together tomorrow, we will merge in the air, and then dock, you will be transferred directly, and then you can go home together." ”

Joseph laughed.

He shook his head while laughing, but inadvertently looked through the entire command hall of the ship.

The more he looked, the more uneasy he became.

As the commander, he is also the captain of Artemis.

But own ship...... and people's boats......

They can even grow vegetables, cook rice, and even fry sugar in space!

- Tonight, they ate the freshest vegetables.

All right...... Not comparable.

Taking another sip of the teacup, Joseph hid his emotion and embarrassment.

Putting down the cup, feeling the gravity that is the same as the earth, he hesitated for a moment and asked, "By the way, did you land through the anti-gravity force field?" ”

Professor Huo Liang and Captain Yang looked at each other, and the two of them smiled and nodded at the same time: "It is more convenient to have this take-off and landing, and then the artificial gravity is more comfortable, and the others are actually of little use." ”

From the moment the Moon Invitation decided to broadcast live, it meant that the anti-gravity force field and the gravity force field would become an open secret, and at this time, there was no need to hide it.

However, although it is public, the degree of secrecy of this force field is very high...... It's unimaginable.

Let's put it this way, even Captain Yang and Professor Huo, one captain and one of the ship's chief scientists, don't have any technical access rights.

It's just that Professor Huo Liang is involved in the design of the spaceship, and he knows that the anti-gravity force field and the gravity force field are both hidden in the hull of the ship - you have to take it off, unless you dismantle the spaceship, you don't want to see what the gravity module looks like.

Hearing Captain Yang say that it was not "of great use", the expressions of the three Artemis astronauts became strange.

"That's ...... Technology that can change the world! ”

"Where? Didn't you come up in the same way? Professor Huo Liang smiled and said modestly: "It's useless, just enjoy it more." ”

"That's different." An astronaut took over and said, "If anti-gravity technology is applied to cars, then in the future, it will be possible to realize aerial flying cars on the ground in science fiction worlds." ”

Professor Huo Liang laughed: "The air car may be a little difficult, because the attitude is not easy to adjust, and the driving track is not easy to plan. However, it is estimated that it can be used on airplanes......"

"That's also remarkable, and the Inviting Moon's engine can also support the ship's design to be larger, which can be used for ocean trade......"

"Haha, that's not our concern." Professor Huo laughed: "After all, we have just entered the era of fusion, and we have only just taken the first step to develop the moon, and it seems that it is still too early to achieve energy freedom." ”

"That's not necessarily, at your speed, next time you come, it's another factory......"

"No, no, it can't be that fast."

"You've always been fast."

"Hehe, we're just a little bold, it's just a fluke." Captain Yang smiled and glanced at his watch: "It's almost 0 o'clock, why don't we get ready to rest?" ”

……

Seeing the three of them climb the gangway and walk to the living cabin, Captain Yang and Professor Huo Liang looked at each other again, and both of them smiled at the same time.

Artemis's astronauts are really very disciplined after they come up - astronaut manual, Artemis has a lot more terms on his side than here.

But abiding by the rules doesn't mean that they are not "curious" and want to inquire about the follow-up of the Yueyue.

These people are inseparable from the follow-up mission and lunar development of the Yueyue, so naturally there is no way to continue the conversation on this day.

"Lao Mei is indeed a little anxious." Professor Huo Liang smiled and sighed: "I heard Mr. Ye say that they are going to get Musk's ship to land on the moon and build a space factory." ”

"But they don't have a gravitational force field, so it's certainly inconvenient." Captain Yang thought about it, reached out and pressed it under the glass table, and the glass lit up.

This table is actually a monitor panel.

"You see, without an anti-gravity force field, they can only land vertically, although SpaceX has a lot of experience in vertical landing and recovery, but that is operating on Earth. When you land on the moon, you have to get equipment down......"

The screen shows a mock-up of a spaceship with its butt on the ground.

Captain Yang shook his head: "Even if the support frame is opened, it is difficult to dance on the tip of the knife." ”

Professor Huo smiled: "Actually, it's nothing...... Mainly, if they see us going up to the sky next time, not only will the Yueyue come up, but there will also be a 3,000-ton cargo ship behind them...... Do you think their mentality will explode? ”

"Hahaha!" Captain Yang's voice resounded in the command room.

……

The next morning, the Moon sent two lunar rovers to bring Joseph and the other three who were to be left behind back to Artemis, and then began the final preparations before takeoff.

First of all, the ground equipment, everything that should be taken away should be taken away, and what should be left behind should be thoroughly inspected.

The second is the warehouse inspection, even if there is an anti-gravity force field, but the cargo box in the material compartment must ensure that Ah Quan and stable, especially the helium 3 storage tank, that is not a problem at all.

Then there are the astronauts' personal belongings, which must be put into the box when taking off to ensure that there is no random flight during acceleration.

At last...... Nature is a variety of lunar soils and minerals.

This time, they brought back five tons of lunar soil and water ice.

Anyway, if various scientific research institutions want to study, it is enough to put it in a sack, and there is no need to talk about grams as before.

When everything was ready, the Invitation Moon finally activated the force field on the night of July 28 and slowly lifted into the air.

Three days later, the Moon decelerated to a predetermined speed in Earth's orbit and began to follow Earth's gravitational pull and embark on a journey back to Earth.
