MTL - The Science Fiction World of Xueba-Chapter 481 Centauri alpha

"Alin, you are here."

Mu Donglai was surprised by the arrival of Pang Xuelin and Mu Qingqing.

All these years Pang Xuelin is entangled in everything, and he can meet with Mu Dong all year round.

That is, Mu Qingqing, occasionally come back when he has time.

Mu Donglai wanted to meet the two, it was not easy.

Especially in the past few years, Mu Dong came to learn that Pang Xuelin and Mu Qingqing were preparing to build an interstellar spacecraft to explore outer space. The old man exploded immediately, firmly opposed, and even let Mu Qingqing and Pang Xuelin divorce.

After all, the only daughter who was abducted by Pang Xuelin on a spaceship that would never be able to return is equivalent to a goodbye after separation.

Later, as the Ark plan aroused global attention, and the media's exhausted reports, the national and global governments and people's attitude towards the Ark plan changed greatly, and Mu Donglai gradually opened his heart.

In his words, if he is ten years younger, he also hopes to join this plan.

It is a pity that he is now a rare year, no matter from the physical condition or the function of the other boat plan, there is no way to join this plan.

Next, Pang Xuelin and Mu Qingqing lived in Chang'an.

Mu Qingqing spent most of her time with her father, while Pang Xuelin chatted with Ren Zhengfei, Ni Guangnan and Huang Zaixing every day to talk about the company's future and the company's future development direction.

If Pang Xuelin left, he and Mu Qingqing had no children, so how to deal with the assets under his name in the future became the focus of media attention.

In the past year, Pang Xuelin has cooperated with the government to complete the nationalization of some assets.

For the rest of his assets, he is prepared to take out 10% and set up an education foundation to support primary and secondary education in poor areas of the country.

Other assets are distributed step by step to the employees of Xinghuan Group in accordance with the real-world Warwick model.

Of course, employees only have the right to pay dividends and no control over their rights. Once they leave the company, they have to sell the shares to the company at the agreed price.

This is very beneficial to the stability of the company's future development, or to maintain the company's future vitality.

Pang Xuelin and Mu Qingqing spent nearly a month in Chang'an before leaving.

This time, they and 38 other reserve crew members will go to Ark One, which has been built in space, to perform a two-year sea trial and training mission.

Two years passed quickly.

Two years later, on December 21, 2012, the day of the end of the world in the Mayan calendar, Pang Xuelin was also selected as the expedition day.

Hainan, Wenchang Space Launch Site.

Hundreds of thousands of aerospace enthusiasts from all over the world gathered in Wenchang to crowd the entire Wenchang County.

If it is not the official deliberate control, there may be more people coming to see off for this expedition.

Global media have focused their attention on this expedition ceremony that attracts worldwide attention.

This is the greatest adventure in human history.

Its historical significance is comparable to that of the Magellan voyage around the world. Columbus even discovered the New World.

The heads of more than fifty countries of the United Nations and more than one hundred representatives from various countries also came to the scene.

At the expedition ceremony, Pang Xuelin, as the captain of Ark One, received the emblem of the Ark Project from the hands of the UN Secretary General. A metal disc made of titanium alloy was engraved with the sun and eight planets of the solar system.

In addition, the circumference of the disk is also engraved with basic parameters such as pi, Planck constant, gravitational constant, speed of light, and fine structure constant, which represent the basic cognition of the universe and nature.

Scientists originally hoped to mark the specific location of the solar system on it, but with the vigorous opposition of Pang Xuelin, it finally disappeared.

Of course, compared to the star exploration plan in China, the Ark plan proposed by Pang Xuelin has many more tasks.

Among them, the most important task is to release a small unmanned probe on the Ark One when approaching a star system.

The probe also carried solar sails, and then gradually slowed down into the stellar orbit by decelerating the solar sails.

In this way, the Ark project can not only meet the requirements of Pang Xuelin to explore as many stars as possible, but also provide in-depth exploration of every passing star.

Even in the detection of Proxima Centauri (the closest star to the solar system), scientists have also considered plans to return unmanned probes.

As for the ultimate success, everything is unknown.

But for humans, the Ark Project is the first cry of human civilization to this universe.

After completing the expedition ceremony, Pang Xuelin, Mu Qingqing and the remaining 18 explorers went to the lounge to make a final farewell with friends and family.

In the lounge, Shuiwa and his wife, Liu Qi, Sanshou, Mu Donglai and others have been waiting for a long time.

Liu Qi is now nearly fifty years old and still maintains a weight of more than two hundred catties.

When embracing Pang Xuelin, the earliest partner who worked with Pang Xuelin couldn't help crying.

"Brother Pang, take care in the future. If it is not a child, I will definitely follow you."

When embracing Shuiwa, he red eyes, but just thumped Pang Xuelin's chest a few times.

"Brother Shuiwa, in the future, Uncle Mu and Aunt San will ask you to take care of you."

"Relax, I will take care of the second elder."

Shuiwa nodded heavily.

Finally, Pang Xuelin came to Mu Donglai.

Mu Donglai did not cry, but instead looked at Pang Xuelin with a smile.

Instead, Mu Qingqing was crying in his father's arms.

"Xiao Pang, Qingqing, I'll give it to you, you must take care of her."

Pang Xuelin took Mu Qingqing's hand and said in a deep voice: "Uncle Mu, I will definitely take care of Qing Qing."

The farewell time of more than an hour soon ended, Pang Xuelin, Mu Qingqing and the remaining 18 adventurers left the lounge one after another.

The eighteen adventurers who participated in the Ark program this time were carefully selected from the 15 million applicants all over the world and had undergone rigorous training.

Considering the dangers of the Ark project and the various crises that may be triggered in the future, these 18 adventurers have an average degree of master's degree or above, nine men and nine women. In the past two years, these people have been combined Couple.

At 21:25 in the evening, in the attention of the global public, the space shuttle officially launched.

Four hours later, the space shuttle docked with Ark-1 in geosynchronous orbit.

Eight hours later, the space shuttle and Ark One departed and returned, and Ark One began to change the angle of the solar sail, officially starting the long journey.

...

Alpha Centauri, also known as South Gate II, is a tri-star system located in the southern part of the sky, Centauri, the closest star system to the Sun.

The integrated magnitude is -0.27 (more than the fourth brightest Arcturus), and the absolute magnitude is 4.4.

Alpha Centauri was once known as the outermost guide of the Southern Cross. Because the Southern Cross is too far to the south, most of the Northern Hemisphere is not visible. It was rumored that Zheng He used to use it to guide the direction.

This is the closest star system to the Sun, only 4.37 light years (about 277600 astronomical units).

Its interior is divided into ABC Samsung, where A / B constitutes a double star system.

Alpha Centauri A is the main star in the South Gate two-binary system, slightly larger and brighter than the Sun. The star is yellow like the sun, and its star spectrum is classified as G2V. By determining the mutual orbital parameters, astronomers concluded that its mass is greater than the sun by about 10% to 12%, and its radius is greater than the sun by about 20% to 25%. The rotation speed of the star is 2.7 ± 0.7km · s, and the rotation period is 22.5 days, which is 3 days shorter than the rotation period of the sun (25.2 days).

Alpha Centauri B is a companion star in the South Gate two-binary system, slightly smaller and darker than the Sun. This main sequence star is orange, and its star spectrum is classified as K1V. Its mass is about 90% of the sun, and its radius is about 86% of the sun. The rotation speed of the star is 1.1 ± 0.8km · s, and the rotation period is about 41 days. Although Alpha Centauri B is darker than Alpha Centauri A, it emits more X-ray energy than A.

Alpha Centauri C, also known as Proxima Centauri, is the third star of the Centauri alpha triad, 0.25 light-years away from the A / B binary system.

This main sequence star is red, and its star spectrum is classified as M5Ve, which means that it is a small main sequence star. Its B? V color index is +1.9, and its mass is 0.122 solar mass (128 Jupiter mass).

Proxima Centauri is 4.24 light-years away from the sun and is also considered to be the closest star to the solar system.

Observing the universe from the vicinity of Nanmen II, you will see many celestial bodies seen by observers on Earth. Most of the constellations have little change, such as Orion and Ursa. But the brightest star in Centauri will disappear, and the sun will become a star of magnitude 0.48 in Cassiopeia.

In general, the shape of Cassiopeia will change from \\\\ / \\\\ / to / \\\\ / \\\\ /, and the sun will be at the tail end of Cassiopeia ε.

Bright stars near the sun observed from Nanmen II, such as Sirius and Nanhe III, will appear in a very different location. Sirius will become part of Orion, appearing at a distance of 4 degrees 2 degrees from the constellation, and slightly dimmer than observed on Earth (-1.2 etc.).

Although Beiluojimen and Vega are far apart, they will be replaced.

Proxima Centauri will become an unobtrusive 4.5-magnitude star, considering that it is only 1/4 light-year away from Centauri alpha star A and Centauri alpha star B, which shows that Proxima star is so bleak.

If there is a planet around Alpha Centauri A or Alpha Centauri B, on this planet, they will be very bright double stars.

For example, if there is a planet similar to the Earth at the position of A1.25 astronomical unit of Alpha Centauri (revolution period is 1.34 years), the brightness of Alpha Centauri A is similar to the sun for the planet, while Alpha star B will be dimmed from 5.7 to 8.6, but will still reach -21.0 to -18.2. Although it is 190 to 2700 times dimmer than Alpha Centauri, it is still 170 to 2300 times brighter than the full moon.

Conversely, if there is a planet similar to the Earth at the position of astronomical unit B 0.71 Centauri (revolving period is 0.63 years), the brightness of Centauri alpha B is similar to that of the sun for the planets, while Centauri alpha Star A will be dimmed from 4.6 to 7.3, but will still reach -22.1 to -19.4. Although it is 70 to 840 times dimmer than Alpha Centauri B, it is still 520 to 6300 times brighter than the full moon.

For a planet orbiting one of the stars, the second sun does not adversely affect climate or photosynthesis (approximately equal to the distance between Saturn and the sun).

But this means that for about half a year, the night sky is not dark, but dark blue, and people can walk around and even read without artificial lighting.

In the "Three Body" series, the Centauri alpha Samsung system was written by Da Liu as a triad of similar mass and distance, because the orbital instability of the three stars led to the planetary orbit in which the three-body civilization lives It is also extremely unstable, sometimes captured by one of the stars, and sometimes wandering around the three stars, the era of the era and the chaotic era alternate, one after another, thus forming a very unique three-body civilization.

But in this world, Centauri alpha is basically consistent with reality.

Because of the launch of the Ark Project, before Pang Xuelin and their departure, scientists on Earth mobilized a lot of resources to observe Centauri α.

Among them, a team of scientists at the Geneva Observatory in Switzerland has discovered an exoplanet around alpha Centauri B.

The size and composition of this exoplanet seem to be very close to Earth, and the planet itself is also in the habitable zone of Alpha Centauri B.

In addition, the European Southern Observatory also discovered a planet around Proxima Star. This planet is named Proxima b, and its mass is about 1.2 to 1.3 times that of the Earth. , The revolution period is about 11 days, and its location is just in the livable zone.

The team of astronomers at the Andalusian Institute of Astrophysics in Spain used the ALMA radio telescope array to detect the presence of three dust bands around Proximity Star. Holding a multi-planet system.

Therefore, according to the orbit planned by Pang Xuelin and physicists, Ark-1 will directly release the unmanned probe at a light-year distance from the neighboring star.

In the future, the detection mission of Proxima Star will be mainly performed by unmanned detectors.

The Ark One is aimed at the A / B binary system of Alpha Centauri.

November 8, 2045 AD.

The Ark One hibernation warehouse.

Pang Xuelin opened his eyes suddenly, the door opened silently, and MOSS's voice rang in Pang Xuelin's ear.

"Professor Pang, you have been hibernating for 22 hours and 26 minutes on August 12, 30th. The MOSS will wake you up according to the predetermined procedure. The Ark spacecraft will pass the Proxima star one month later and arrive at the A / B binary star two years later. Next, You will have two years to research the Centauri alpha Samsung system! "
