The 2019 Chinese science fiction disaster film, based on Liu Cixin's novel of the same name, directed by Guo Fan, starring Qu Chuxiao, Zhao Jinmai, Wu Jing, Li Guangjie, Wu Mengda, and Sui Kai.
In 2075, the sun is aging and expanding rapidly, the earth is constantly plagued, and it has become no longer suitable for human habitation, and scientists have found that after a hundred years, the sun will engulf the earth, and the solar system will cease to exist after three hundred years. In response to this impending catastrophe, the world set up a coalition government and launched the Wandering Earth Project, trying to take the Earth out of the solar system and find a new home for mankind.
Humanity has done its utmost to build 10,000 planetary engines on the surface of the earth, using all its resources to fly the earth to a new home 42,000 light-years away. The entire plan period of 2500 years, need to last dozens of generations, and in order to ensure the continuation of human civilization, human beings built a pilot space station in space, storing embryos and seeds of earth animals and plants, once the wandering earth plan fails, the space station will carry human civilization to continue to move forward.
Leaving the solar system requires the earth to stop rotating, so the earth's temperature drops rapidly, the tides are abnormal, the surface is no longer suitable for human habitation, and humans build dungeons as temporary shelters, and can only live below before reaching a new home, but the number and space of dungeons are limited, only half of the human beings are accommodated, so they can only decide whether to go or stay by lottery. Chinese astronaut Liu Peiqiang gave up treating his wife with cancer and allowed his son and his grandfather to enter the dungeon, and the father-son conflict arose.
Fifteen years later, earth entered jupiter orbit, and scientists envisioned using Jupiter's gravitational pull to accelerate the earth. Liu Peiqiang, the first to enter the space station, has completed his service and is about to return to Earth to reunite with his family, and he has handed over his work to pack up and prepare to go home.
Liu Qi is his son, with his sister cheated two sets of equipment and identity after sneaking out of the dungeon to the ground to play, outside minus eighty degrees, Liu Qi stole his grandfather's driver's license to drive the carrier car to set off, because the technology is not home, was stopped by the traffic police to find the car stolen after detention, grandpa Han Ziang to the detention center to redeem people, people did not fish out and were also locked up together, just encountered an earthquake, the family took the opportunity to run out to drive the carrier with Tim to escape.
It turns out that the earth has changed its orbit due to the gravitational influence of Jupiter, causing a super earthquake, a large number of engines are turned off and stopped, if humans cannot restart the engine within 37 hours, the earth will be directly absorbed by Jupiter, causing irreparable consequences. The coalition government called for the planetary engine to be restarted at all costs, and all of humanity entered a state of emergency, calling for vehicles carrying flint stones to the nearest engine.
The rescue team requisitioned Han Ziang's carrier, and the group went to Hangzhou to restart the engine, passing through the frozen Shanghai in distress, because the gravitational force strengthened, the earthquake came at any time, the rescue team was trapped, and had to abandon the vehicle to go on foot. Liu Peiqiang learned that the earth was in danger, forced out of the dormant warehouse, found that the space station was about to be evacuated, because the artificial intelligence calculated that the earth would be attracted to Jupiter, there was no hope, so he decisively abandoned the wandering earth plan and started the tinder plan.
The rescue team tried to carry the flint through the building, but in distress halfway through, Han Ziang and a team member were killed in the building, Liu Qi blamed the rescue team for his grandfather's death, and parted ways with them. And Liu Peiqiang believes that the space station abandons the earth is a defection behavior, and the Russian small partner went out of the warehouse to the space station command center, ready to start manual operation, the result of the companion was killed, with his life to help Liu Peiqiang difficult to come to the control room, but found that it was the instruction of the coalition government, unable to manually control.
The rescue team continued to carry the flint to the Hangzhou No. 1 engine, but found that the engine and the dungeon had been destroyed in the earthquake, the female team members were angry and used their guns to extinguish the flint that brought them disaster, just when the rescue team was about to disband, Liu Qi found a carrier truck to meet them.
After Liu Qi and the two left, they encountered Li Yiyi, an emergency technical observer waiting for rescue, and failed to repair the engine, and he persuaded Liu Qi to drive to find someone to continue to save the earth. They prepare to go to Sulawesi in the equatorial region to turn the engine, and learned from the radio on the way that humans have repaired all the steering engines and 70% of the planetary engines, but the power generated is not enough to free the earth from Jupiter's gravity, that is to say, the earth is only a dead end, and the coalition government tells the survivors to use the remaining seven days to accompany their families and wait for the end to come.
In three hours, Earth will break through Jupiter's rigid Roche limit and disintegrate under the influence of Jupiter's gravitational pull, plunging humanity into desperate final madness.
In desperation, Liu Qi thought that Jupiter is a planet full of hydrogen gas, in case of fire and explosion, is it possible to use the shock wave of the explosion to help the earth get rid of Jupiter's control, Li Yiyi felt feasible, but the key is how to ignite Jupiter, gather all the earth engine energy pooled in the Sulawesi engine, maybe it works.
When everyone arrives at their destination, they are rescue teams that give up hopes to go home and enjoy the last time of their lives, and no one is willing to help them try, so they can only rely on themselves. Li Yiyi arranged for the soldiers to be divided into three ways, Liu Qi and Tim were responsible for installing new flint stones, Wang Lei led the rescue team to start the firing pin that hit the flint, and he was responsible for modifying the procedures of the main control room in order to maximize the power of the engine, let the tongue of fire touch Jupiter's atmosphere, and detonate Jupiter.
After the split action, Liu Qi's sister used Liu Qi's emergency call authority to contact Liu Peiqiang on the space station and said their plan, Liu Peiqiang informed all mankind of this plan through the radio, and the sister tearfully requested to move many rescue teams that did not want to sit still, they turned the front of the car and chose to come to support.
Several teams completed the scheduled task without any danger, although some paid the price of their lives, Li flicked the switch one by one, and the energy pooled and spewed out, but unfortunately there was still a distance of five thousand kilometers from Jupiter's atmosphere, and mankind fell into despair again. Liu Peiqiang saw that the space station's fuel was enough to replenish this last distance, so he acted arbitrarily, and the space station was ignited by a broken ship, and the coalition government had to grant it manual control, and after detaching the dormant bunker from the main body of the space station, he drove the space station to the flames.
After the last call with his son, Liu Peiqiang was buried in space, but his plan was successful, Jupiter was ignited, the shock wave of the explosion helped the earth out of Jupiter's gravity, and everyone rushed to hide in the dungeon to avoid the huge shock wave, and the earth was able to continue to wander in space.
