Neptune, the farthest planet from the earth, has now revealed its mysterious face.
The whole Neptune is bright blue. It looks very beautiful.
It's not because Neptune is full of sea water and has nothing to do with water.
Neptune shows this color because its atmosphere is full of methane.
The methane gives Neptune a light blue color, which is why the planet seems to be full of seawater, which has nothing to do with the real water.
Neptune was named after the Roman god of the sea because it looked like it was covered with sea water.
In fact, Neptune doesn't even have liquid water, let alone the sea water that covers the entire planet's surface.
So Neptune's name does not conform to his state, this is not the territory of Neptune, it is just a human fantasy.
Yesu is very interested in Neptune, at least the appearance of the planet makes him like it.
Looking at the light blue planet in front of her eyes is getting bigger and bigger, Ye Su's curiosity is even stronger.
This time Yesu arrived at Neptune on the pioneer, not just for a test voyage.
Exploring Neptune is also an important purpose, and it is also the reason why Ye Su decided to choose the destination of this test voyage.
Neptune has never landed before, and it is an unknown land for human beings.
Except for Voyager II's brief passing, humans know nothing about Neptune.
What's on this planet, what's on the earth's surface, we don't know anything about it.
It is precisely because of Neptune's mystery to mankind that Yesu wants to find out.
Yesu has a special probe on board the pioneer, which is to land on Neptune.
While Yesu was still enjoying the beauty of Neptune, a crew member came to him.
"Captain, now that the ship has reached Neptune's orbit, will it slow down?"
Now everyone is used to reporting to Ye Su and regards him as his captain.
The real captain has now been ignored by all, and can only watch Yesu command over there.
After arriving at Neptune, the spacecraft must slow down for a period of time before it can get close to Neptune's orbit.
If the trailblazer continues at its current speed, it will head into Neptune.
If you hit Neptune at such a fast speed, I'm afraid even one person on board will not survive.
No one wants to see this situation, so we have to slow down now.
Slowing down from half the speed of light to rest is not to say that it can be reduced by decreasing.
The spacecraft needs to slow down from 150000 km / s to a standstill.
The whole deceleration process also takes some time, so the crew came to ask Ye Su's opinion.
"Start slowing down now, and slowly dock the spacecraft into Neptune orbit."
"Remember not to be too close to Neptune, in case the spacecraft will be captured by Neptune's gravity."
After hearing the crew's inquiry, Ye Su turned his head and gave his own instructions.
With Yesu's command to slow down, the pioneer's thrusters adjusted their direction and began to spray flames in the opposite direction, producing a thrust in the opposite direction.
This thrust will continue to slow down the spacecraft until the trailblazer is able to dock smoothly in Neptune's orbit.
It took more than ten minutes to accelerate to the highest speed of the spaceship. Of course, it took the same time to slow down. This is determined by the power of the spacecraft. It is impossible to be faster.
After more than ten minutes of deceleration, the spacecraft slowly approached Neptune.
Now the entire Neptune in Yesu's eyes, has become very large.
Looking at Neptune all over the place, it's a completely different picture.
What used to look like a sea water planet can now see the flow of clouds.
Light blue clouds move at surface height, as a result of storms on Neptune.
Don't forget that Neptune's storm is the most violent in the solar system, and its maximum speed can exceed 2000 kilometers per hour.
The landscape caused by such a violent storm looks magnificent.
Yesu sees one fast-moving storm after another, colliding with Neptune.
When the trailblazer finally came to a standstill, the trial was half done.
The next step is to explore Neptune, and then you can set out to return to earth.Ye Su then sat back to the captain's exclusive seat and began to direct the crew to land the probe.
"Start releasing the detector and pay attention to the status of the detector."
"Don't let the probe go too fast. Neptune's atmosphere is full of methane. Too fast will make the detector burn."
After Ye Su finished the precautions, the crew members under Ye Su began to take action.
A spherical probe was released by the Pathfinder and began to fly toward Neptune.
Soon the probe skimmed Neptune's atmosphere and approached Neptune's surface.
This detector has been specially designed by Yesu and can withstand very extreme environments.
First of all, the spherical shape of Neptune can withstand less impact force in the severe storm, so that the detector can avoid being damaged by the storm.
You know, Neptune has the most severe storms in the solar system, so it's impossible to use a spherical design.
In addition to its spherical appearance, the detector is also strictly protected from cold.
The heat insulation layer on the surface of the detector is all re developed by Yesu, which can withstand very low temperature.
Neptune is always below - 200 degrees low temperature, if the insulation layer performance is not good enough, I am afraid the internal parts will be frozen out of effect.
From the harsh environment above Neptune, we can know why Yesu is going to land with a probe instead of a manned one.
In this extremely harsh environment, manned landing is too difficult.
