Voyage of the Stars

With the experience of the previous thousand years of sailing, this fifty-four year voyage is considered to be very familiar.

Even because of the technological progress of the Ross 154 star for more than ten years, this voyage does not require hibernation shifts. You can directly take long-term hibernation pills, then lie down in the hibernation cabin, close your eyes, and wake up to your destination.

In the past ten years in the Ross 154 star system, not only has hibernation technology improved, but because of the experience of a thousand-year voyage, humans are really afraid of another thousand-year voyage. Under such pressure, various high-performance materials have emerged in an endless stream.

Based on the advancement of material technology, the stability of human machines and equipment is now very good. Electrical equipment, for example, can run for seven to eight hundred years without any problems.

Therefore, this voyage can be regarded as the most comfortable time for mankind since the disaster occurred.

After a fifty-four-year voyage, human beings gradually woke up from hibernation after walking for fifty-three years.

The purpose, in addition to adapting to the mental trance and some adverse physical reactions caused by long-term hibernation, is to have the Hope brake and then send the Pioneer probe to the Wolf star system for detection.

Dispatch of probes is routine.

Human beings who understand the dangers of the universe cannot rush into an unknown star system carelessly if they are well prepared.

About 0.2 light-years away from the Wolf star system, Hope began to adjust its attitude.

Steering push machines located throughout the structure of the Nozomi begin working, turning the Nozomi from a head-pointing position to a tail-pointing position. Then, start the five main fusion thrusters to slow down.

After completing the deceleration, the Hope continued to sail toward its destination at 1% of the speed of light for the next period of time. During this process, the Hope will turn the direction of the ship back again. After the probe completes the detection of the Wolf star system, the Hope will speed up again and enter the galaxy.

These actions don't seem complicated, and they are indeed not complicated with current human technology, but they are quite time-consuming, especially on detectors.

According to scientists' calculations and speculations, Hope may need to stay in the Wolf Galaxy for a year in order to wait for the confirmation detector to confirm the target situation.

This is already fast. Without fusion thrusters, this kind of exploration of the interior of a star system would have taken fifty years.

The probe that performs the mission has been built before humans went into hibernation, and now it just needs to be launched.

It is worth mentioning that although the probe is called a probe, it actually looks like a spacecraft, but it is smaller. Humans designed its shape into a melon seed shape. According to the designer, this took into account the possibility that the probe may fly in the planet's internal atmospheric environment.

The power used is of course also a nuclear fusion propeller, which is a single-engine engine.

The entire detector, or detection spacecraft, is about the size of a passenger plane, but it has no wings and its melon-seed streamlined shape makes it look very technological.

Its appearance is undoubtedly more in line with ordinary people's fantasy of spaceships than the large barrel-shaped Hope.

Humanity immediately sent ten such detectors to the Wolf star system. They will be assigned to main sequence stars and various planets for various types of detection according to their different focuses.

Time passed slowly in the detection and processing of various detection data, and the internal situation of the Wolf star system gradually became visible to human vision.

The first is the main sequence star of the Wolf 1061 star system, which is a red dwarf star. There are many red dwarfs in the universe. These guys are small and long-lived. Wolf 1061 is a typical red dwarf.

Its age is 7.29*10^9 years, and its mass is 0.25 times that of the sun. The diameter is 0.307 times that of the sun, which is 427159.8 kilometers. The surface temperature is 3342K, or 3068.85 degrees Celsius, and the rotation period is 8.47 Earth days.

The Fe/H metallicity is -0.09, which means that the logarithmic difference between the star's iron-to-hydrogen ratio and the sun's iron-to-hydrogen ratio is -0.09. Because humans use the sun as the standard of measurement according to their own habits, that is, the solar Fe/H is zero, so what this means here is that the metallicity of the star is lower than that of the sun.

These parameter data are brought to humans by detectors that mainly observe stars. In addition, there are also spectral data, apparent magnitude, absolute magnitude, axis inclination, surface gravity acceleration, stellar activity parameters, etc. of the star. .

These data may seem useless, but in fact they are very important to humans because they include data on other stars, which are important data for humans to understand stellar evolution and even explore the theory of universe evolution. Not only that, they can also enrich human databases and provide future information for humans in the interstellar space. Various positioning, routes, and making star maps during navigation are of great significance.

Detector data shows that there are three planets in the Wolf star system. Humans named the one closest to the main sequence star Wolf 1061 b, and the two outer ones are Wolf 1061 c and 1061 d.

The three planets are all rocky planets. Wolf 1061 b, which is closest to the main sequence star, is the smallest, but has a diameter of 15,372 kilometers, which is 1.2 times that of the Earth. However, because it is too close to the star, this planet is very hot. According to the data returned by the orbiting detector, its surface is yellow and has been severely baked and weathered. The average surface temperature is 446.5 degrees Celsius, but there is no sign of a volcanic eruption.

As for Wolf 1061 d, it is a planet with a diameter 1.98 times larger than the Earth. Not only is this planet large, but it also has a beautiful dust ring similar to the rings of Saturn in its orbit. Compared with Wolf 1061 b, this planet appears to be very cold because of its distance from the main sequence star, with a surface temperature of about -121 degrees Celsius.

Of course, these two planets are not the focus of human detection this time. The most important thing for humans is Wolf 1061 c. It is true that as humans have known before, this planet is located inside the habitable zone.

Its surface calm temperature is 56.5 degrees Celsius. For the universe, such a surface temperature is considered rare. Other data about this planet were also quickly transmitted to the Hope.

This is a planet with a large amount of water. Its atmosphere is mainly composed of water vapor, oxygen, carbon dioxide, nitrogen, sulfur dioxide and a small amount of rare gases. The overall mass is 3.4 times that of the Earth, its diameter is 1.54 times that of the Earth, and its surface gravity is 1.4299G.

Although sulfur dioxide is present in the atmosphere, other parameters are so excellent for humans that it is indeed worthy of its name as a super-Earth by experts in the 21st century.

Judging from the various parameters of this planet, although due to greenhouse gases, the peak surface temperature of the planet will reach 70 degrees Celsius, and the atmospheric pressure will also reach 7 standard atmospheres, these problems are not major.

If there was no silver mist threat in this star field, it would be no problem for humans to even want to settle here. Overall, Wolf 1061 c is a mild planet with a super ocean.
