"It's getting closer and closer to the Sand Star, this guy is really a few sizes bigger than Earth!!"

Future has successfully slowed down and entered the gravitational range of Alpha Centauri B. Now that it was heading towards the Sand Star, Lynn looked excitedly at the huge pale yellow planet suspended in the starry sky outside the window, and his complexion looked slightly better today.

"And the dung star on the side is not small, and it can be seen so clearly at this distance. Also, sure enough, the more I look at it, the more it looks like shi~t! ”

Smith looked with interest at the Dung Star next to the Sand Star.

"This is the end of our interstellar journey that has lasted nearly 9 years!!" Yuan Haochen muttered to himself.

As the distance got closer, the Sand Star began to become larger and larger, and gradually occupied the field of vision of Yuan Haochen and others.

"It's incredible! Our previous spectral analysis was correct, and the blue-green patches were the lake and the greenery. cough~cough~"

The agitated words added a burden to Lynn's respiratory system, and he quickly took out the oxygen supply device and took a deep breath.

"Lynn, you better not talk too much." "But it's really exciting to discover a habitable planet," Smith advises with concern. ”

Lynn nodded, but still couldn't hide her excitement.

"Coming into orbit around the target planet." Future's intelligent navigation flight system issued operational reminders to the three of them.

Because all the operating parameters of the Mirai spacecraft, as well as the information of the real-time camera, will be packaged and transmitted back to Earth as soon as possible, they do not need to do additional communication work, and the Earth command center will know what is happening on the Mirai spacecraft today in more than 4 years.

"Has entered the orbit of the target planet." The Intelligent Navigation Flight System continues to broadcast.

Looking at the sand star in front of him, Yuan Haochen suddenly became full of ambition.

After all, it took a long time and a distance of 40 trillion kilometers to finally stand in front of this habitable planet.

"Under this alien land, is there any hope for the earth's civilization...... this is the question that Yuan Haochen has always been most concerned about.

In addition to the scientific and technological heritage of the Creator World buried in the planets, there is also a high possibility that it is a satellite left in the universe, or other probes, space stations and other devices and equipment.

Therefore, after entering the orbit around Sand Star, the Future spacecraft launched three exploration satellites in the outer space of Sand Star.

Each of the three satellites will have its own duties, each covering Sand at an angle of 120 degrees, and the electricity obtained on the satellites will be mainly converted by the light energy of Alpha Centauri B.

On the one hand, these three satellites will continue to search the outer space of Sand Star, in the hope of finding satellites or probes left over from the Creator's civilized world.

On the other hand, they can also set up a communication detection system to help the Mirai spacecraft fully grasp every move on Sand Star.

............

"The spacecraft begins to enter the atmosphere of the target planet." The Intelligent Navigation Flight System continues to broadcast flight conditions.

Hara, Smith and Lynn were already sitting firmly in the safety seats.

According to previously proven data, the mass and gravity of Sand Star exceed that of the Earth, and even the concentration of the atmosphere is slightly higher than that of the Earth.

Therefore, the process of entering the Sand Star will definitely be more bumpy than expected.

All three began to stare with bated breath, and the only sound of breathing and various electronic devices running in the entire Future control room was the sound of breathing and various electronic devices.

"The spacecraft is 9,000 kilometers from the planet's surface."

"The spacecraft is 5,800 kilometers from the planet's surface."

"1,200 kilometers from the planet's surface."

"180 kilometers from the planet's surface."

"Start adjusting the spaceship's flight attitude!"

......

As Future's flight speed decreased, its inertial centrifugal force also began to decrease, and it was gradually pulled to the ground by the strong gravitational pull of Sand Star.

Although through observation, there were no risk factors on the surface of the Sand Star, for the sake of safety, Yuan Haochen and the others finally chose a plain with a relatively pure environment as the landing site of the Future for the sake of safety.

The landing site is about 5 kilometers away from the nearest oasis, and the reason why it did not land directly near the oasis was because of the fear of unnecessary trouble.

They believe that if there are movable life forms on the surface of Sand Star, then it is more likely that the area where they operate is near the oasis.

If the Future landed on the edge of the oasis, there was a great risk.

After confirming the coordinates of the landing area, the intelligent navigation flight system calculates the re-entry angle and flight trajectory of entering the atmosphere of Sand Star, and formulates a set of accurate and reasonable deceleration plans.

Against the backdrop of two dazzling "suns", a bright spot suddenly appeared in the sky of the Sand Star.

The bright spot gets bigger and darker.

It was the first interstellar spaceship in the history of earth civilization that flew from the distant earth - Future, which flew across the sea of stars all the way.

Perhaps Future: The first spacecraft to visit Sand in 2.1 billion years, following the departure of the Creators.

The Future began to slowly descend towards a vast sandy and gravel desert, and the powerful air currents instantly rolled up the billowing sand and dust in the sky.

"The spacecraft has successfully landed, and now the analysis of the atmospheric situation begins." The intelligent navigation flight system is still working.

"Main components of the atmosphere: carbon dioxide 48.1%, nitrogen 36.2%, oxygen 12.9%, argon 1.2%, methane 0.9% ......"

The results of the atmospheric composition analysis came out quickly, and they were basically the same as the previous spectral analysis conclusions of Yuan Haochen.

"In the universe, it's pretty good to be able to encounter such air quality." Yuan Haochen looked at the results of the analysis of atmospheric composition and said, "There are no toxic gases in the atmosphere, but the carbon dioxide content is too high, the oxygen content is low, and direct breathing will still have a negative impact on our health." ”

Carbon dioxide is stable and non-toxic, but it cannot supply human breath and is a suffocating gas. When the amount of carbon dioxide in the air is too high, it also puts a burden on human breathing.

The oxygen level of 12.9% is roughly equivalent to the oxygen content at an altitude of 4,000 meters on the earth, so if they stay on the Sand Star for a long time, Yuan Haochen and others will be like being on the plateau for a long time.

"The air temperature outside the spacecraft is 35 degrees Celsius, the atmospheric pressure is 1.3 standard atmospheres, and the gravity is 122% of the Earth......"

(According to the formula for calculating gravitational acceleration: g\'=gm/(r^2), g is the gravitational constant.) Combined with the mass and radius of the Sand Star, the actual gravity level can be calculated. ）

The gravity level of 22% in multiple places will of course not affect Yuan Haochen's movements, but it feels like carrying a 15-kilogram package, and time will naturally add a certain burden to their body. (To be continued.) )
