Chapter 756: Detecting Neptune

Neptune, the planet farthest from the earth, has now lifted the veil on his face, revealing his mysterious appearance.
The whole Neptune is shining light blue and looks extremely beautiful.
This blue color is not because Neptune is full of sea water, and has nothing to do with water.
The reason why Neptune shows this color is because the atmosphere is full of methane.
Methane stained Neptune with a light blue color. This is the reason why this planet seems to be full of sea water, and has nothing to do with real sea water.
Originally, Neptune was named because the planet looked like it was covered by sea water, so it was named after the sea in Roman mythology.
In fact, there is not even liquid water on Neptune, let alone the sea water covering the entire surface of the planet.
So Neptune's name does not fit his state, this is not the territory of Poseidon, it is just a beautiful fantasy of mankind.
Ye Su's interest in Neptune is still quite big, at least the look of this planet makes him really like it.
Seeing the light blue planet in front of him keep getting bigger, Ye Su's desire for knowledge became even stronger.
This time Ye Su came to Neptune on the Trailblazer, not just for the spacecraft's trial voyage.
Detecting Neptune is also an important goal, and it is also the reason why Ye Su decided on the destination of this trial.
Neptune has never landed by a probe, and it is a completely unknown land for humans.
Except for Voyager 2's short-lived accident, mankind knows nothing about Neptune.
Human beings don't know what is on this planet and what the specific conditions of the surface are.
It is precisely because of Neptune's mystery to humans that Ye Su wanted to find out.
Ye Su brought a special detector on the Pioneer this time, just to land on Neptune to find out.
While Ye Su was still enjoying the beauty of Neptune, a crew member walked up to him.
"Captain, now that the spacecraft has reached the orbit of Neptune, is it starting to slow down?"
Now everyone is accustomed to reporting to Ye Su, completely treating him as their captain.
The real captain was now ignored by everyone, and could only watch Ye Su command over there.
After the spacecraft reaches Neptune, it must decelerate for a period of time before it can approach Neptune's orbit.
If the Pioneer continues to maintain its current speed, it will bump into Neptune.
If you hit Neptune at such a fast speed, even one person on the entire spacecraft might not survive.
No one wants to see this situation, so we must slow down immediately.
Slowing down from half the speed of light to standing still does not mean that it can be reduced by reducing it.
The spacecraft needs to slowly descend from a speed of 150,000 kilometers per second to a standstill.
The entire deceleration process will take a while, so this crew member will come to ask Ye Su's opinion.
"Start to slow down right away, and slowly dock the spacecraft to the orbit of Neptune."
"Remember not to get too close to Neptune, lest the spacecraft is captured by Neptune's gravity."
After hearing the crew's question, Ye Su turned his head and gave his instructions.
Following Ye Su's deceleration command, the propeller on the Trailblazer adjusted its direction and began to spray flames in the opposite direction, generating a thrust in the opposite direction.
This thrust will continue to slow down the speed of the spacecraft until the Pathfinder can dock smoothly in Neptune's orbit.
It took more than ten minutes to accelerate to the highest speed of the spacecraft. Of course, it took the same time to decelerate. This is determined by the power of the spacecraft, and it is impossible to go faster.
After ten minutes of deceleration, the spacecraft slowly approached Neptune.
Now the entire Neptune has become very huge in Ye Su's eyes.
Observing Neptune in the entire position is a completely different scene again.
The planet that originally looked like sea water, can now see the flow of clouds.
The light blue clouds move at the height of the earth's surface as a result of the storm on Neptune.
Don’t forget that the storm on Neptune is the most violent in the solar system, with a maximum speed of more than 2,000 kilometers per hour.
The landscape created by such a severe storm still looks magnificent.
Ye Su saw one after another fast-moving storm, constantly colliding on Neptune.
When the Blazer finally stopped, half of the work was completed for this trial.
The next step is to explore Neptune, and then you can set off to return to Earth.
At this time, Ye Su returned to the captain's exclusive seat and began to command the crew to carry out the detector landing work.
"Start to release the detector. Pay attention to the status of the detector."
"Don't let the detector go too fast. The atmosphere of Neptune is full of methane. Too fast will make the detector burn."
After Ye Su finished talking about the precautions, Ye Su's crew began to take action.
A spherical probe was released by the Pathfinder and began to fly towards Neptune.
Soon the probe skipped the atmosphere of Neptune and approached the surface of Neptune.
This detector has been specially designed by Ye Su and can withstand very extreme environments.
First of all, the spherical appearance is in the violent storm of Neptune, which can withstand a smaller impact, so that the detector can avoid being damaged by the storm.
We must know that Neptune has the most violent storm in the solar system, so it will not work without a spherical design.
In addition to the spherical appearance, this detector has also been subjected to strict cold protection.
The thermal insulation layer on the outer surface of the detector is a new material developed by Ye Su, which can withstand very low temperatures.
Neptune is always at a low temperature of more than 200 degrees below zero. If the performance of the insulation layer is not good enough, the internal parts may be frozen and useless.
From the harsh environment above Neptune, you can know why Ye Su used a probe to land this time instead of manned landing on Neptune.
In this extremely harsh environment, the difficulty of manned landing is too high.
