Chapter 124 Super Earth

With the experience of the previous thousand-year voyage, this fifty-four-year voyage is also a breeze.

Because of the technological progress in the Ross 154 star system over the past decade, there is no need for hibernation rotation this time. You can take long-term hibernation medicine directly, 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 the hibernation technology improved, but humans are really afraid of another thousand-year voyage because of the experience of the thousand-year voyage. Under such pressure, various high-performance materials have emerged in an endless stream.

Based on the progress of material technology, the stability of human machinery and equipment is now very good. For example, electrical equipment can run for seven or eight hundred years without any problems.

So this voyage can be regarded as the most comfortable one for humans since the disaster.

In the fifty-four-year voyage, humans woke up from hibernation one after another after fifty-three years.

In addition to adapting to the mental trance and some adverse physical reactions caused by long-term hibernation, the purpose is to brake the Hope and then send the pioneer probe to the Wolf star system for exploration.

Sending probes is a routine operation.

Humans who know the dangers of the universe will not rashly rush into an unknown star system if they are prepared.

When the Hope was about 0.2 light years away from the Wolfe star system, it began to adjust its attitude.

The steering thrusters located in various parts of the Hope structure began to work, turning the Hope from pointing its head to the destination to pointing its tail to the destination. Then, the five main fusion thrusters were started to decelerate.

After the deceleration was completed, the Hope continued to sail to the destination at a speed of 1% of the speed of light for a period of time. During this process, the Hope will turn the direction of the ship back again, and wait until the probe completes the detection of the Wolfe star system, and then the Hope will speed up again and enter the interior of the galaxy.

These actions do not seem complicated, and they are indeed not complicated for human current technology, but they are quite time-consuming, especially on the probe.

According to scientists' calculations and speculations, in order to wait for the probe to confirm the target situation, the Hope may need to stay in the Wolfe star system for a year.

This is already fast. If there is no fusion thruster, this kind of action of detecting the interior outside the star system will take at least fifty years.

The probe for the mission was built before humans hibernated, and now they just need to launch it.

It is worth mentioning that although the probe is called a probe, it actually looks like a spaceship, but it is relatively small. Humans designed its appearance into a melon seed shape. According to the designer, this also takes into account the possibility that the probe may fly in the atmosphere inside the planet.

The power used is of course a nuclear fusion propulsion system, which is a single-engine engine.

The entire probe, or the exploration spacecraft, is about the size of a passenger plane, but it has no wings, and the melon seed-shaped streamline makes it look very technological.

Its appearance is undoubtedly more in line with the general public's fantasy of spacecraft than the large barrel-shaped Hope.

Humans sent ten such probes to the Wolf star system at once. They will be assigned to the main sequence stars and various planets for various types of exploration according to different focuses.

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

The first is the main sequence star of the Wolf 1061 star system, which is a red dwarf. There are many red dwarfs in the universe. These guys are small in size and long in life. 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. Its diameter is 0.307 times that of the sun, which is 427159.8 kilometers. The surface temperature is 3342K, that is, 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 iron-hydrogen ratio of this star and the iron-hydrogen ratio of the sun is -0.09. Because humans use the sun as a measurement standard according to their own habits, that is, the sun's Fe/H is zero, so what this means is that the metallicity of this star is lower than that of the sun.

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

These data may seem useless, but they are actually very important to humans, because they include other star data, which are important data for humans to understand stellar evolution and even explore the theory of cosmic evolution. Not only that, they can also enrich human databases, which are of great significance for various positioning, routes, and star map making in future interstellar navigation.

The probe data show 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 outside are Wolf 1061 c and 1061 d.

All three planets are rocky planets. Wolf 1061 b, which is closest to the main sequence star, is the smallest, but its diameter is 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 sent back by the orbiting probe, its surface is yellow and has been severely weathered. The average surface temperature is 446.5 degrees Celsius, but there is no sign of volcanic eruption.

As for Wolf 1061 d, it is a planet with a diameter 1.98 times larger than that of the Earth. This planet is not only large, but also has a beautiful dust ring similar to Saturn's ring in its orbit. Compared with Wolf 1061 b, this planet is very cold because of its distance from the main sequence star, and the surface temperature is calm at around -121 degrees Celsius.

Of course, neither of these two planets is the focus of human exploration this time. Humans are most concerned about Wolf 1061 c. Indeed, as humans know before, this planet is located inside the habitable zone.

Its surface calm temperature is 56.5 degrees Celsius, which is rare for the universe. Other data of this planet were quickly transmitted to Hope.

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

Although there is sulfur dioxide in the atmosphere, other parameters are so good for humans that it is truly worthy of being called a super-Earth by experts in the 21st century.

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

If there is no silver fog threat in this star field, humans will even want to settle here. Generally speaking, Wolf 1061 c is a mild planet with a super ocean.
