444 Roaming 2

The world's media gathered together to build momentum for the space complex's maiden voyage; but this real space adventure was rarely touted by public opinion.

Because this is not a stage for ordinary people. Ordinary people can spend money to enjoy the weightless environment of low-Earth orbit for a few hours, but they cannot endure the torture of weightlessness for nearly ten days. This is originally a mission for well-trained astronauts.

Now it has been replaced by new human superpowers.

Five days later, a very ordinary-looking 959 took off from Narita Airport. From its appearance, it was basically impossible to tell that it was special. Instead, people paid more attention to RB-753 and RB-755, which have frequently appeared in media headlines in recent times. Pay attention to them.

Everything, including two island country pilots in their prime.

Bei Haiyang was forgotten intentionally or unintentionally. This is the selfishness of the nation. They care more about their own children.

Only the plane's hull number still vaguely reveals its difference, Orient Express 01.

In the cockpit, there was only one pilot, Bei Haiyang.

After several months of flying on space routes, people found that two pilots are not necessary for space voyages. It is different from traditional civil aviation that requires the cooperation of two people to check each other's doubts and fill in the gaps. The uniqueness of spiritual power makes the entire flight process

The captain is the one who makes the decision, and the co-pilot rarely has the opportunity to make suggestions.

Because there are no rules and regulations for mental manipulation. Since there are no unified rules, how can we cooperate?

Moreover, ordinary space routes are now very short of people, so they simply implemented a single-pilot strategy; the existence of two pilots can also provide a substitute when one of them becomes unwell, but for these new human superpowers,

Life enhancement makes the body more controllable, and sudden illnesses will no longer affect driving.

Bei Haiyang likes this method very much and is more free to do whatever he wants.

When Orient Express 01 reaches low-Earth orbit, it will basically have to rely on itself for future voyages, and space traffic control will not impose too many restrictions on it, including how to fly to the moon.

"East Pacific Aviation Control, this is Orient Express 01. I have entered low-Earth orbit. It is expected to change orbit within half an hour and enter the Earth-Moon Transfer Orbit in due course!"

East China Sea Space Navigation Control, "Okay, you can control the orbit change conditions yourself. I wish you good luck."

The traditional moon landing flight is a winding journey! It consists of an orbital segment around the Earth (also called a phase-modulating orbital segment), an Earth-moon transfer orbital segment, and an orbital segment around the moon.

The reason why it is so troublesome is actually because of the shortage of power, so it has to rely on gravitational orbit change to achieve the purpose of near moon;

Of course, the spacecraft can fly directly from the earth to the moon, and to be honest, it is not difficult, but the premise is that it must decelerate before landing. No one would like to have a mushroom cloud or fireball attached when landing.

The time can be the traditional 3 or 5 days, but it can also be shorter. The shorter the flight time, the greater the energy required, and the greater the flight speed required when the satellite is at perigee. It brakes when it reaches the perigee of the moon's scheduled orbit.

The greater the force, in other words the greater the force the car requires when braking, the greater the risk.

In order for the aircraft to safely enter the lunar orbit, 5 days is the minimum energy orbit. In the traditional sense, it can carry the least fuel, the smallest load, and the lowest accident rate.

If you want to land gently on the lunar surface, that means that the relative speed of the spacecraft when it reaches the lunar surface is best 0.

A feasible solution is to work the engine in reverse to slow down when it is about to reach the moon. For the audience, the rocket roars away and then makes a beautiful turn and stops. It is undoubtedly very handsome.

However, the aesthetics of most aerospace engineers are different from those of the public. A beautiful turn and emergency stop is a stupid waste of propellant in their opinion. A precise "throwing ball" is more in line with their aesthetics.

"Out" the spacecraft uses the gravity of the earth to gradually decelerate, and the speed decelerates to 0 when it reaches the moon.

This is a standard operation for traditional near-lunar landings. When the collision of civilizations comes and the use of spiritual power to mobilize planetary energy becomes a reality, handsome movements will become possible, because the pilot no longer has to worry about fuel propellant.

A combat spacecraft can easily do this, but a space passenger plane is almost impossible. The consensus is that their kind of space passenger plane does not need to use the traditional winding way to approach the moon, nor can it approach the moon like a combat spacecraft.

The best way to speed up brutally is to circle the earth to speed up, find the right time window to directly enter the earth-moon orbit, break away from the earth's gravity at the farthest end, and change orbit again into the lunar orbit.

It is a compromise and is more suitable for the capabilities of aerospace aircraft.

Bei Haiyang felt that if he exerted all his mental power, he could control even this huge space passenger plane to fly directly to the moon. Whatever orbit was not orbiting, he could just catch Sister Chang'e and chase it, but this might be possible.

It was a bit shocking, but not necessary. He was not in a hurry, and Sister Chang'e was not waiting for him on the moon to drink flower wine.

Therefore, just circle the earth in an honest circle and continue to change orbits.

In traditional aerospace, such a winding orbit requires at least three circles around the earth to reach the earth-moon orbit, but since he does not need to worry too much about fuel, one circle is enough.

In fact, his current orbit is not fixed at all, but is constantly changing, accelerating towards the far orbit!

If an object moves around another object only under the influence of gravity, according to Kepler's law, its trajectory must be an ellipse. Therefore, before the engine ends and the spacecraft approaches the moon, its orbit will be a perigee near the earth.

The apogee is an elliptical orbit 38W kilometers away from the earth, which is the earth-moon transfer orbit.

This can be heard from his constant reports to the ground,

"East Pacific Aviation Control, this is Orient Express 01. My current orbit is 300 kilometers close to the earth and 5,000 kilometers far away..."

"East Pacific Aviation Control, I am currently 400 kilometers away from the ground and 50,000 kilometers away from the ground..."

"Entering the Van Allen radiation belts, everything is normal with the aircraft."

"500 kilometers near the earth, 380,000 kilometers far away, goodbye earth..."

Once entering orbit, you cannot accelerate casually! If you accelerate too fast, you will not be able to stop the car when approaching the moon, and it will rush out of the moon's gravitational field, and you will not know where it will fly.

Therefore, it should be a controllable acceleration state. After flying halfway and 200,000 kilometers away from the earth, he has to consider decelerating.

At his current average speed of 10 kilometers per second, the time it takes to reach the near-lunar orbit is between 10 and 15 hours. It depends on how he slows down, whether he brakes hard or reduces the accelerator and brakes lightly?

The moon is much smaller than the earth, with a weight of 1/80 and a gravity of 1/6. In other words, when approaching the moon, it must slow down to 2.4 kilometers/second or less before it can be successfully captured by the moon.

Doesn't it seem difficult?
