The distance between the moon and the earth is about 384,000 kilometers.

to be honest.

If such a long distance is placed in the earth environment, it will definitely be a very long distance. Not to mention the communication delay problem, whether the signal can be accepted is a huge problem.

but.

The distance of 3.84 million kilometers is placed in a cosmic vacuum environment, which is not too far.

The Earth is about 630 million kilometers away from Jupiter, 55 million kilometers away from Mars, and 384,000 kilometers above the moon is simply a short trip.

For example, after the "Chang'e 4 probe" of Yanguo Space Group landed on the back of the moon, in order to transmit communication signals to the earth from the back of the moon, two "Magpie Bridge" relay communication satellites were launched at the "Lagrangian Point" between the earth and the moon.

In this way, Chang'e 4 will first transmit the signal to the "Queqiao Relay Satellite", and then launch it from the "Queqiao" to the earth to ensure communication between the earth and the probe.

This time, the communication function of the "Moon Orbiter" launched by Phoenix Group was also cooperated with Yanguo Aerospace Group, borrowing the signal frequency of its "Queqiao Relay Satellite" to ultimately achieve smooth communication system.

After thinking for a long time, Hu Lai still felt that there was no need to start a "large-scale phased array communication satellite" immediately.

Although the launch of the "large-scale phased array communication satellite" can make the delay between the earth and the moon lower, there is currently no project between the earth and the moon that has to use such good communication guarantees.

As for the "moon orbiter" that is being promoted now, we can completely use the "Queqiao Relay Satellite" of the Aerospace Group to complete technical experiments.

After thinking through this, Hu Lai temporarily put the idea of ​​producing "large phased array communication satellites" on hold and was ready to concentrate on the next step of the "Moon Landing Plan".

And on the other side.

The successful flight of Phoenix Group's "Moon Orbiter" around the moon was also a huge response from other countries and space agencies around the world.

In fact, after the Phoenix Group initially publicly launched the "moon landing plan", everyone thought that Phoenix Group was a fantasy and unrealistic.

Even after the big dog owners cooperated with Phoenix Group to "land land on the moon", many institutions still laughed at the big dog owners for being cheated with a joke mentality.

Unexpectedly...

Now Phoenix Group has really succeeded in the first step!

You know, it is this simple first step, "orbiter flying around the moon", which is enough to make the space agencies of countless countries jealous!

The one with the greatest pressure is naturally North American NASA.

In the previous incident of "comet hitting Jupiter", Phoenix Group won the favor of many scientific research institutions and universities because it generously provided the impact images and data of "Sky Survey Telescope" to all scientific research institutions around the world.

It also started live broadcasts in the world with historic global launch, which snatched the limelight of NASA and made NASA's prestige in the global aviation field plummet.

And now.

Phoenix Group successfully achieved a flight around the moon as a company, which made their global prestige reach a terrifying level!

NASA Headquarters.

In a senior conference room, many senior engineers from NASA gathered together.

At this moment, they all frowned with their lips and stared at the LED display in front of the conference room. The screen displayed was the latest large aircraft engine released by Phoenix Group - the "220-ton hydrogen and oxygen engine"!

At this time, a Western man wearing glasses stood next to the LED screen. It was NASA's top aircraft engineer, Rui Jackson.

He pointed at the picture of the hydrogen and oxygen engine named "Hot Wheels" on the screen with a serious look, looked at everyone present, and said in a low voice:

"According to data released by Phoenix Group, their 'moon orbiter' ignition from Earth's low-Earth orbit to the moon was successfully captured, which took a total of 80 hours."

"60 years ago, our Apollo spacecraft took 92 hours to fly. The latest flight of their Yanguo's Chang'e 4 took 114 hours, and now they only took 80 hours!"

"I don't need to say more about the reason, it is the 220-ton 'Hot Wheel' hydrogen and oxygen engine developed by Phoenix Group in front of you."

After the words came to an end, the atmosphere at the scene became a little dull, and the audience stared at the latest "Hot Wheels" hydrogen and oxygen engine in front of them.

After a moment, a blonde senior executive immediately raised his hand and asked:

"Ruy, have we verified this data?"

"Are you sure it's true?"

Rui Jackson glanced at the blonde senior who asked the question, then nodded and said:

"reality!"

"Although we have very little information about their 'Hot Wheel' hydrogen and oxygen engine, according to our full monitoring of their 'Moon Orbiter', there is no problem with the data they released."

"It took only 80 hours to be captured from ignition in low-Earth orbit to entering the moon orbit."

Rui Jackson's affirmative confirmation suddenly made the meeting room fall silent, and everyone present knew what it meant.

As we all know, in space environments, whether it is a rocket, an aircraft, or an orbiter, it is due to weightlessness and vacuum environments.

In other words, even if the aircraft loses power, the aircraft will not fall directly on the ground as if it is on Earth, but will float in space all the time.

so.

In view of this weightless feature in space, such as starting from the Earth's orbit and flying to the moon, which is more than 400,000 kilometers long, in order to save fuel, engineers will generally adjust the flight speed of the rocket to a relatively fuel-saving speed.

This situation is similar to driving on earth. The fuel consumption of running 120KM/H and the fuel consumption of running 70KM/H must be relatively lower.

And what about Phoenix Group now?

80 hours!

What is this concept?!

Running 400,000 kilometers in such a short time can only explain one problem.

Phoenix Group has strong engine strength and its fuel combustion efficiency has reached a very high level.

To be honest, I run fast and the fuel consumption is low!

hiss……!

Everyone present could not help but feel the tremendous pressure, but Kerui Jackson did not finish his words.

He gently tapped the screen and a "track path" picture appeared on the screen.

"In addition, we should also pay special attention to the fact that the Phoenix Group's 'moon orbiter' this time did not perform orbital adjustments in low-Earth orbit. Instead, after the rocket was pushed to low-Earth orbit, the 'orbiter' would ignite it directly, and then fly directly to the 'earth-moon transfer orbit'!"

"To put it bluntly, their orbitals did not make any orbital adjustments at all. They rushed straight and flew to the moon on the 'direct route'!"

After saying this, Rui Jackson pushed his glasses, and everyone present had a completely changed face.

You should know that in space, all aircraft and satellites are affected by the gravity of celestial bodies and orbit around celestial bodies.

Under normal circumstances, for example, if humans want to fly from the earth to the moon, they must first enter space at the "first speed of the universe" (7.9KM/S), enter the earth's orbit, and begin to rotate around the earth.

Immediately afterwards, the aircraft will wait for the aircraft to circulate the earth's orbit and then move to the orbit position calculated in advance. The aircraft will begin to change its orbit, escape from the attraction of the earth at the "second speed of the universe" (11.2KM/S), enter the "earth-moon transfer orbit", and then fly to the moon.

When you want to reach the lunar orbit, the aircraft must slow down and change orbit again at a suitable orbit position to enter the "lunar orbit".

For example, when Chang'e-1 flew from the Earth orbit to the "earth-moon transfer orbit", it orbited the earth for 7 days and made three orbital adjustments. The purpose is to save fuel and obtain longer propulsion time.

And what about the Phoenix?

There are not so many fancy ones, and they are so reckless that they can fly directly on the "direct route" to the moon, and they don't have to consider changing orbits at all!

The Phoenix Group can do this, combined with their flight speed of only 80 hours, is not just a problem of engine combustion, but the high-thrust hydrogen and oxygen engine developed by Phoenix may have reached an unprecedented top level, and its thrust is more than enough to cope with the transportation between the earth and the moon!

The engine is great, but it can be reduced by one force to ten times. Everything is much easier!

Thinking of this, everyone present was frightened and chilled!

Not long after, the rocket technology of Phoenix Group has developed so fast?!

Everyone looked at me, and I looked at you, their eyes were full of shock.

It took a long time before someone said:

"It seems that it is not surprising that Phoenix Group's 'recyclable rocket technology' has made rapid progress. They have even solved the problem of high-thrust hydrogen and oxygen engines, and small-thrust engines are naturally no problem."

Rui Jackson nodded and took the conversation.

"It's not the time to discuss their 'recyclable rocket technology', and now our NASA is in a very troublesome situation!"

After saying this, he glanced at everyone and said:

"Although Phoenix Group has only verified the first step in flying around the moon, they have undoubtedly solved the problem of rocket thrust. Maybe they can really land on the moon, or even land on the moon one step ahead of us!"

"Now they have gained great prestige and reputation in the entire aerospace field. If they really let us land our moon in advance, it would be a historic disaster for us NASA!"

"We will completely lose our position as a leader in the aerospace field!"

As he spoke, Rui Jackson's tone became heavier and his eyes finally fell on NASA Director William.

"Chief William, we are having trouble now."

"The International Space Station will be facing retirement soon. Once retired, we will no longer have space stations to use. Our allies will all go to the Yanguo Space Station or the Phoenix Group's 'Voyager Space Station'!"

"And once the Phoenix Group lands on the moon or leads the moon landing, we will face a bigger blow!"

"As for our SLS Rockets, our 'Artemis Plan' is now full of problems, and we can't see the possibility of landing on the moon in the short term!"

"so……!"

"We have reached a very dangerous level now. The last time we could shake our position as a leader in aerospace was when the Soviets sent astronaut Gagarin into space in 1961!"

"We, now we have to do everything we can to compete with Yanguo and Phoenix Group for time!"

After the words came to an end, not only all the NASA executives present, but also Director William, who was in a high position, felt huge and heavy pressure.
