Chapter 229 Knicks Star

"...Now it's the most critical moment! Our A001 spacecraft is constantly decelerating in the reverse direction, and the engine is emitting a light blue ion flame... Here it comes! It's coming! According to the plan, its relative speed with Noah cannot exceed 1500m/s! Of course, the lower the relative speed, the better..."

"The lower, the safer!"

"This scene reminds me of the previous aerial refueling technology, which is equivalent to the relative approach of two aircraft... But obviously, our technology is more difficult... OK, the data is out, the speed is 1000, 900... in line with expectations... It is rapidly approaching the circular orbit!"

"It's landed! Ah!"

With this exclamation, even this senior reporter held his breath and stared at the screen. He even forgot his commentary work!

At this moment, the A001 spacecraft was rushing straight into the circular orbit at a speed of 800 meters per second relative to Noah!

This speed is equivalent to the normal flight speed of the "Boeing 737" aircraft on Earth. But if the "Boeing 737" landed on the ground at this speed, it would definitely be smashed into a pile of rubble, causing a major flight accident, and the probability of survival of the people inside was less than one in ten thousand.

But now it is different, this relative speed is still within the design standard. Of course, it is impossible to land hard, but to slow down through a long circular track!

The powerful magnetic levitation force in the track began to work, and the A-001 spacecraft was instantly subjected to huge pressure from all directions, as if it was firmly grasped by an invisible giant hand in the middle of the track...

The spacecraft floated in the middle of the circular track, moving around the track at high speed, but it did not touch the walls on all sides!

It began to decelerate at an acceleration of 3g, that is, 30 meters per second squared. After about 20 seconds, it turned a quarter of a circle around the circular track, and the speed was successfully reduced to 20 meters per second.

At this time, the magnetic levitation pressure in the track turned into electromagnetic attraction. The scaffolding fell, the spacecraft landed steadily on the ground, and then slowly docked at a nearby three-dimensional docking station.

"Perfect...success!"

The reporter shouted subconsciously, and then realized that he was broadcasting live. He quickly said: "Let us cheer for the flying warrior Matt Beach with the warmest applause. Let us also praise those researchers who have worked hard silently..."

Noah has already cheered! People shouted and witnessed all this with their own eyes, as if they were there, and their hearts are still beating wildly!

Don't look at the spacecraft like a ping-pong ball, it stopped before it turned half a circle around the orbit.

This is a high speed of 800 meters per second!

Such a landing technology is something that earthlings could not do in the past!

In the captain's room, Yu Yifeng also excitedly high-fived Xu Yunjin and others.

While everyone was talking, several researchers had already started to analyze the data very quickly. They played back various details of manual flight, fault tolerance, and various possible emergency measures, etc.

After analyzing all the data, everyone breathed a sigh of relief.

In other words, with human physical ability, as long as the pilots are properly trained, they can still control these high-speed spacecraft.

However, such a spacecraft is almost the limit of human flesh.

If the spacecraft is faster, the human nervous system may not be able to control this speed, unless it is a superhuman like Yu Yifeng...

Let's not talk about other things for now. The successful completion of the last flight test also means the maturity of human aerospace technology.

People can finally calm down and deal with the upcoming landing on Nix!

...

At the current distance, Nix can be clearly seen through the radio telescope.

Astronomers have been observing it for a long time!

As expected, this dim planet is full of thick atmosphere, and three tiny satellites revolve around it. Of course, humans choose to land on Nix instead of the tiny satellites.

"Here... is our second home in the future?" Yu Yifeng stayed in the astronomical observatory and muttered to himself.

For some reason, he always had a faint feeling of discomfort. It was too dark and too cold. The overall environment was not even as good as Mars! Not to mention the earth!

He swore in his heart that people would never be satisfied with this planet of eternal night. Humanity will eventually become an interstellar civilization and find its true second home!

At eight o'clock that evening, a celebration meeting was held at the government square.

Three years of preparation time passed quickly, and most of the original plans have been completed. Even if they were not completed, it was indeed too difficult and beyond the current technological level. It was not that the researchers were not serious.

Of course, as the supreme leader of Noah, Yu Yifeng must also be present, talking to the staff, shaking hands to express gratitude, presenting trophies, etc.

After a series of ceremonies, everyone was filled with joy.

This is the honor they deserve. Many jobs not only require mental labor, but also some dangers, and even preparations for life!

For example, the soldier Matt Beach actually went to test fly with a kind of awareness.

So, no matter what, Yu Yifeng must thank them.

Needless to say, the process...

After the celebration, the next step is real observation and... landing!

People first use radio telescopes to observe from a distance, and then after a few days, the slowing Noah will be captured by the gravity of Nix, and then artificial satellites, drones, reconnaissance robots, etc. can be released.

Yu Yifeng is not idle either, he is checking various materials in the office.

The astronomy report in his hand lists various data in detail:

"Nix has an overall density of 0.68 times that of the Earth, and a radius of 1.96 times that of the Earth. The surface gravity is about 1.34 times that of the Earth!"

"Its rotation period is 38 hours, which is equivalent to a little more than 1.5 days for humans, and its revolution period is more than 100,000 years, which can be ignored..."

"The geological activity is intense, and the surface magnetic field strength is 13 times that of the Earth!"

"It has a thick atmosphere on its surface, and the surface pressure is 2.6 times that of the Earth's atmospheric pressure! Its composition: 80.3% nitrogen, 14.8% oxygen, 3.4% carbon dioxide, 0.9% argon, and the rest is a small amount of carbon monoxide, ammonia, hydrogen sulfide and other gases."

Yu Yifeng narrowed his eyes. There is such a high concentration of oxygen!

This means... Can it be directly breathed after filtering out toxic gases and microorganisms?

No, he shook his head. Even if microorganisms are excluded, such high air pressure will destroy the oxygen balance in the human body. Gases such as carbon dioxide will dissolve in the blood to a large extent, causing hypoxia in the human body.

The human body is still too fragile. Even if the atmosphere is more suitable for breathing, it is impossible to adapt to this air pressure. It is necessary to wear thick power armor.

Ordinary humans can withstand about 6 atmospheres, but that is only for a short period of a few minutes. 2.6 times the atmospheric pressure of the earth, although it is not unbearable, will definitely cause harm to the human body.

Fortunately, people have fully enclosed power armor, so it doesn’t matter even if the air pressure is higher.

But then again... where does so much oxygen come from?

Generally speaking, the oxygen content of a lifeless planet cannot be so high! Only natural phenomena such as lightning can produce a small amount of oxygen.

But now, the oxygen concentration of 14.8%... does it mean that this planet has life?

Is there any large life?

This is a very critical point!

People have not found artificial satellites near Nix, so it is impossible for high-tech civilization to appear here...

He frowned and continued to read the report: "This planet has a carbon dioxide concentration that is 100 times that of the Earth, and a methane concentration that is 30,000 times that of the Earth. It has a very serious greenhouse effect and there are traces of active volcanic activity!"

"Because of the greenhouse effect of volcanoes and the atmosphere, although it is far away from the star, its surface temperature is higher than expected, with an average temperature of minus 120 degrees...but local volcanic areas may be above zero degrees Celsius, with abundant geothermal energy and conditions for the birth of life!"
