The Hope spacecraft passed through deep space. It happened to encounter Jupiter 12 days later. The huge planet was extremely shocking to see for the first time, even at close range. Each of the surging air currents was enough to blow the earth away. The rumored huge plaque also made Yan Xia couldn't help but take pictures. But there was no circle of friends to post. Yan Xia looked at some celestial bodies around Jupiter and suddenly thought of something. "Ella, stay for a while and launch a detection drone into Europa." Europa is an ice planet with a thick layer of ice on its surface. Scientists on Earth speculate that there may be a liquid ocean under these ice layers, and based on Earth's experience, where there is water, there will be life. Europa is likely to have life.
The reason why Yan Xia decided to launch a drone up is simple. 1 It is to collect life samples on it. 2 It can also replenish a large amount of liquid water for the spacecraft. The food originally carried by the spacecraft had been eaten long ago. He has been eating synthetic proteins, synthetic fats, synthetic carbohydrates, synthetic sugars produced by Ella... Everything is technology and hard work. A large amount of liquid water can be put into the water cycle, and the 18% agricultural space can also be used. Yan Xia remembered that he still had some seeds. The spacecraft stopped in the outer space of Europa. Thirty drones flew away from the spacecraft and landed on the surface of Europa. Yan Xia saw the landforms on Europa through the camera. It was indeed a snowfield. The drone began to dig deep, and finally broke through the ice layer after 57 kilometers deep and entered a water world. After electromagnetic detection, the depth of the ice layer and water of Europa is 113 kilometers, which is 102 kilometers deeper than the deepest part of the ocean on Earth. The drone began to store a lot of water, and then returned to the spacecraft through the cable hanging from the spacecraft. It took only 10 days to do all this. For the time scale of the universe, it can be ignored. The samples brought back were studied. Ella's two-dimensional leather suit was surprised. "Yan Xia, life is indeed widely present in the universe." "Traces of microorganisms were found in the water of Europa. This is a kind of microorganism that does not exist at all in my database."
A photo appeared on the screen. It was a microorganism similar to a grassworm, but it was ten times larger than a grassworm. This was already an extremely complex life form. If conditions allowed, intelligent life might be born on Europa in hundreds of millions of years. It took ten hours. Water had been stored for 5,000 meters, which was probably enough. "Ella, open the planting area and plant all those seeds." Yan Xia's words were not responded to. After a while, Ella appeared solemnly, and a picture was played on the screen in front of him. The sun became extremely bright in a short time. He knew. It was the fragments of the earth falling into the sun. A strong solar storm came, and it reached the X level almost instantly. The value on the screen rose from X1 to X122, and it was still increasing. Under the special energy monitoring lens, the originally dim sun turned orange-yellow, and a series of terrifying energy released from its surface spread to the surrounding universe in the blink of an eye. This solar storm released the energy equivalent to 150 billion hydrogen bombs exploding simultaneously in just 10 seconds, which is unprecedented. It swept everything like a cosmic sandstorm, and everything except celestial bodies involved would be ruthlessly destroyed. "Fly at maximum speed, Ella!" "Okay, Yan Xia!" The only good news is that the main material speed of this terrifying invisible sickle is only 679km/s. ... Yan Xia entered the dormant cryostat again after the Hope entered the flight state. This time it is the second-generation cryostat, which is much safer than the previous generation, and there is no need to drink the anti-coagulant. Sleep. Eternal sleep. This time it will be longer, so long that he himself does not know when he will wake up. Ella manages everything in the spacecraft alone, and uses all computing power to calculate the most cutting-edge technology. It uses the huge gravity of Jupiter to accelerate. The speed increased from to 815km/s. In addition to facing some rays, it escaped the proton impact of the solar storm.
… 88 days later, the Hope spacecraft arrived in the orbit of Pluto, which is 41 astronomical units away from the sun. This dwarf planet, once the ninth largest planet in the solar system, carries too many stories about the development of human astronomy. At its farthest point, Pluto can reach the dark deep sky 49 astronomical units from the sun. It is a boundary marker, standing in the Kuiper belt, and there is only the Oort cloud outside. Most of the matter in the solar system is in the Kuiper belt, and there is only the vast universe outside, which is even more empty. Pluto is not in the direction of their advance at this time, and Ella did not observe Pluto. Here, Ella controlled the huge camera with a diameter of ten meters outside the spacecraft to take a photo of the way it came. The whole photo was occupied by a bright spot, which was very small but extremely bright. The sun was still in intense activity at this time. Venus, Mars, the asteroid belt, Jupiter and Saturn have all been swallowed up by violent energy. It is unknown whether the machines left in the asteroid belt can withstand it. ... Another 773 days passed. After enduring 6 shock waves at the edge of the heliosphere, the Hope completely escaped from the solar wind. That means they are safe. Here, Ella received a signal. It used a telescope to shoot in that direction. After a lot of analysis, it found a small black dot that was inconspicuous in the universe. It analyzed that it was the "Voice of the Earth". It should be Voyager 1, and its route is also Proxima Centauri. This is the farthest probe launched by humans. Today, 168 years after it left the earth, the Hope spacecraft caught up with it. It is now 2145. The battery of this probe has run out of energy, and Ella caught up with it and captured it. It carries the human fantasy of the universe. Some people on Earth once wondered whether Voyager 1 and Voyager 2 would be captured by other civilizations, and then other civilizations would detect human civilization. This worry is completely unnecessary. The time when Voyager reaches the edge of the solar system should be 42145 AD, which is 40,000 years later. For advanced civilizations that can travel long distances in interstellar space, they can already detect the existence of Earth civilization outside the solar system. Voyager is just the icing on the cake for alien civilizations to determine the form of Earth civilization. Ella made some minor modifications to the probe, reinstalled the nuclear battery, and then launched it to the same orbit at the original speed of 17km/s. It replenished the power.
After that, it will send its own information back every year. However, this probe no longer knows that its voice will not be received by anyone. At this time, they have reached a distance of 420 astronomical units from the sun. However, the long road has just begun. ... 9 years later. Hope entered the edge of the core of the Oort Cloud. This place is also called the comet cloud, the legendary home of comets, and is filled with water ice, methane, ethane, carbon monoxide and hydrogen cyanide. Ella collected some samples for research. … After another 279 years, the Hope broke away from the huge core layer of the Oort Cloud and entered the boundary of 50,000 astronomical units. … 288 years passed in a flash again, and the Hope spacecraft completely broke away from the Oort Cloud, and the surrounding area became a dead black space. Looking at the sun here again, it has merged with the starry sky background. At this time, the voyage time is 578 years, and the distance from the sun is 100,000 astronomical units, about light years, which is also the boundary of the sun's gravity. The Hope has truly flown out of the solar system. It also represents the first time that mankind has gotten rid of its main star. … After 86 years of flying out of the solar system and 664 years of space travel. A bright beam of light came from the side of the Hope and hit the Hope. "Alarm!" "Alarm!" "Traces of extraterrestrial civilization have been found AU away, and the spacecraft has been attacked by extraterrestrial civilization." Yan Xia was awakened again, and what he saw was the flashing red alarm.
