Neptune's lunar spacecraft is partly brought to space in the form of ship girl equipment, deployed to the airport module of the Space Force Port, and finally generated by consuming resources.

The size of these aircraft has reached the scale of large transport aircraft, with a maximum take-off weight of more than 200 tons.

The second phase of expansion is an unfinished space force port. It is a block with a side length of 64 meters. The expansion is a block with a side length of 128 meters.

In the atmosphere, a 64-meter-long runway, let alone a large transport aircraft of 200 tons, would be difficult to take off in World War II propeller fighters.

Even if it expands to a 128-meter runway, a 20-ton modern carrier-based aircraft must use catapults to take off.

But now times have changed. Here are the space military ports and space airports. Everything here is theoretically flying in the sky.

So the plane here does not need a runway at all, just throw it out.

Inside the 64-meter-long military port, only a lunar aerospace transport aircraft can be inserted into one floor, and the original block isolation wall must be opened, occupying a large amount of space.

Therefore, such large transport aircraft can only use external space terminals or airports.

The so-called external dock is actually a few long metal poles that can be retracted. They are based on the frame of the space base and extend in four directions around them.

There are fixtures on the long pole, which can tie the plane to the pole like a sheep.

Because aircraft and military ports are relatively stationary, as long as the aircraft and base do not re-strengthen the orbit, these two hundred-ton large aircraft can be fixed by not being too strong.

However, the need for afterburner changes is often present, so the aircraft at the space base will only be generated when used, and the first thing to do is to leave the fixed pole when taking off.

Neptune and Yuanwang 1, the two leaders, flew out of the space base with another 10 aircraft carriers that transported cargo and 4 battleships responsible for working, flew out of the space base and drifted into the transport plane closest to the space base.

Neptune and Yuanwang 1 guided the 12 ship girls to sit down, tied their seat belts, and then sat directly in the driver's seat.

Press the start button and wait until the transport aircraft system self-test is completed. Neptune selects the lunar route from the navigation system, then presses the tower communication button and reports to the microphone:

"Yun-101 lunar aerospace transport aircraft, the self-inspection of the No. 001 aircraft has been completed, preparing for the first lunar exploration mission, and now apply for takeoff!"

Within the Space Force Port, Wuhu, a ship girl, has taken over the management mission of the Space Force Port Terminal Airport with the assistance of Yuanwang 2 and Polaris.

After receiving Neptune’s application and reviewing the relevant tasks, press the communication button to reply:

"The mission has been confirmed and the takeoff is allowed."

The sound of Wuhu sounded in the plane at the same time, followed by the automatic return communication of the military port system:

"The transport plane is being unlocked, wait a moment.

"The lock is released and you can take off."

Neptune was a little excited. After confirming the news, he took a deep breath, pushed the control rod, and controlled the plane to slowly leave the space military port.

At this time, the trajectory of the moon's aerospace transport aircraft is highly consistent with the space military port, which means it is still orbiting the ship girl star.

If a lunar spacecraft is directly launched into space from the surface of the planet, it usually needs to fly around the planet at least one or even many circles.

The engine is turned off when flying around the track, so it won't waste fuel when flying around, it will just waste time.

The relevant personnel happened to check and verify the status of the spacecraft during this period.

Even satellites that fly out directly at once, such as Chang'e-2, have to fly most of the way around the earth, check and accelerate in the process, and then run along the earth-moon transfer orbit.

The spaceship that takes off in space driven by Neptune does not need this process, and the self-test is completed before taking off, so it directly enters the next stage - orbit change.

Valley

Even if this direct orbital change is completely different from that of ordinary Earth and Moon aircraft.

Ordinary Earth-Moon aircraft usually accelerate in the Earth's orbit, constantly lengthening and flattening its orbit, making its aliquots farther and farther away.

Until his apogee coincides with the orbit of the moon, and he and the moon fly to the same point at the same time, and he is just perturbed by the moon's gravity.

Then he slowed down and changed his orbit again, broke away from the super flat orbit around the planet, and moved to the flat orbit around the moon.

Then continue to slow down around the moon, shortening the orbit around the moon from a long time until it falls to the surface of the moon. This process usually requires several circles.

After Neptune's plane left the military port, it directly adjusted the direction of the transport plane, pushed the engine's power to the end, and flew hard towards the orbit of the moon.

Even if you fly to the moon in a straight line, considering the relative position and rotation of the planet and the moon, the final actual trajectory will be an arc.

However, the trajectory of the spacecraft itself relative to this system can be regarded as a straight line.

Neptune's plane can run to more than ten kilometers per hour. Calculate the orbits of the planet, moon, and planes, and only takes more than ten hours to reach the moon.

The reason why Neptune's spacecraft does this is because normal earth-moon flights are too wasteful.

The simple flight of the Earth-Moon transfer orbit starts at more than 100 hours, and it takes longer to enter the moon into orbit.

The big moon of the Ship Girl Star has a longer orbit than the moon on Earth and takes longer.

The reason why Neptune's spaceship dares to fly directly is because the plane carries more than a dozen "ships" and the fuel is almost infinite.

The fuel that the plane filled itself is enough to fly directly to the moon. When you come back, just ask the ship girl to refuel it.

In the end, Neptune's lunar aerospace transport plane flew about 16 hours and arrived at the orbit of the large moon more than 400,000 kilometers away.

Since it was a calculated trajectory, when the plane arrived, it happened to meet with the bypassing moon.

According to the prompts of the navigation system, Neptune had already started to slow down on the way, so the spacecraft flew upside down at this time.

The engine exerted force in the reverse direction to offset the speed of the spacecraft's advance.

But at this time, Neptune only turned on two auxiliary engines, and the deceleration momentum did not increase to the maximum.

Because what Neptune is considering is that if the speed is slowed down too much, the plane will fly slowly, and it will take longer to arrive on the moon.

So when the plane is about to converge with the moon, its overall speed is still higher than the second cosmic speed of the current galaxy.

If the plane continues to fly like this, it will turn a small turn next to the moon and continue flying outward.

The goal of this mission is the moon, so of course we cannot continue flying out.

So Neptune pressed several buttons in a row to turn on all the engines of the plane, so that the speed of the plane would plummetly decrease.

After the plane circled the big moon for half a circle, it finally completely stopped its momentum of flying out and entered an extremely flat and long orbit around the moon.

Neptune allowed the plane to continue to maintain full-force reverse acceleration, causing the orbit to shrink to an altitude of only 200 kilometers in just two hours.

On this track, you can basically perform tasks normally.

After confirming the orbital stability state again, Neptune turned off all engines and allowed the plane to start flying around the big moon.
