Its orange-red appearance is due to the fact that the surface is covered with hematite (iron oxide). The diameter of Mars is about half that of the Earth, and the inclination and rotation period of its rotation axis are similar to those of the Earth.
Since the development of aerospace, Mars has always been a second home that humans are eager to transform.
NASA's Ares 3 exploration project sent a small team of scientists to Mars to begin preliminary research.
As a botanist, Mark Watney focuses on water temperature, soil science and environmental science. His research work will be the key to whether humans can complete plant cultivation and obtain food stably.
But after living on Mars for 135 days, Mark Watney was not in a good mood because his teammates abandoned him and left Mars on the eighteenth day of the research mission.
On the eighteenth day of the research mission, he and five other astronauts encountered a huge storm, and their journey into outer space had to end early. During the evacuation process, Mark was blown away by the building rolled up by the storm, and the anchor penetrated him.
life detector.
He was left on Mars because he was mistakenly thought to be unable to survive, and became Space Robinson.
Like Robinson Crusoe, he had the supplies left over from the entire spaceship, but these supplies could only support his survival for more than ninety days.
Mark used everything a botanist could do. He used the poop left by himself and his teammates to make fertilizer, used rocket fuel to create oxygen and water, and successfully cultivated potatoes on Mars.
If the plan goes well, he can take the Ares 4 rocket and return to Earth during the next Hohmann transfer window.
But this is if the plan goes well, he will survive alone on Mars for 868 days, together with the potatoes he grows.
However, all plans were shattered last night.
On the night of the 134th day of his life on Mars, when Mark went to check his potato cultivation warehouse, the isolation material ruptured, causing the cultivation warehouse to lose pressure.
The plants all died. The complete loss of pressure caused the plants and surrounding water to vaporize. The bacteria that survived in the poop and used as fertilizer also died in the subzero temperature of Mars.
Without the breeding barn, Mark could no longer plant and could only eat his remaining potatoes and strictly follow the rationing system to survive until the 609th Martian day.
The next spacecraft rescue will require 868 days on Mars, and death on Mars has become a foregone conclusion.
It takes 414 days to launch a rocket from the earth to Mars. The efforts of the earth have become the key.
Mark could only place his hope on the earth's efforts. After cleaning up the plantation, he could not care about dealing with his own wounds.
While talking to the monitor, Mark recorded his psychological activities and life, which can be used as research materials for those who come after him, and can also be used as proof that he has lived.
While dealing with the injury at the corner of his eye, Mark said a little naggingly: "On the 135th day, my breeding warehouse exploded. I can only place my hope on the earth. I know in my heart that I have done everything I can, and hope that the goddess has given up.
Got me."
With a self-deprecating laugh, Mark continued: "I don't know if it's an illusion. When I recognized the reality clearly, I could already feel the god of death knocking on the door. It was like the loneliness of flying alone on a space station. I felt like there was someone there.
Banging on your cabin door outside…”
"Just like this..."
Mark was tapping on the table as he spoke, and the tapping sound gradually overlapped with the sound he heard.
With a swipe sound, Mark bounced up and yelled: "This is not an illusion! There is really something knocking on the door!"
But this is on Mars! There is no life on Mars! How could anyone knock on his cabin door?
Mark was frightened and quickly put on his Mars protective suit. The weak protection provided by the protective suit gave Mark some confidence.
Arriving at the cabin door cautiously, Mark indeed heard the knocking sound outside.
‘嗵~嗵~嗵~’
Be regular, rhythmic, and even patient.
In order to ensure safety, the hatch of the Mars base is not designed with an observation window.
Mark could only do some mental construction for himself through the cabin door.
Things are already so bad, how much worse can they get? Will we meet aliens?
Mark suddenly laughed when he thought of this. He turned on the camera on the protective suit and prepared to start recording.
After taking a deep breath, Mark began to adjust the pressure of the isolation cabin and then opened the door.
"Oh my god, big brother, you really take a long time to think!"
After Mark opened the hatch, before he could see the surrounding environment clearly, this sentence appeared in his ears.
The atmospheric pressure of Mars is 500 to 700 Pa, and the density is less than one percent of that of the Earth. But speaking at such a close distance allowed Mark to successfully distinguish that this was the language of the Earth.
Mark, who breathed a sigh of relief, was in the mood to look around. He saw a team of eleven people. They were all wearing full-coverage spacesuits. The spacesuits looked somewhat similar to those used in the space station, but their lightness had surpassed that of the space station.
Clothes.
After all, an extravehicular spacesuit weighs 120 kilograms. No one can wear it and move freely on Mars and still knock on the door.
When Mark was dazed, a hand slipped in front of his eyes. The person he had just communicated with was waving in front of his eyes, trying to awaken his consciousness.
"Are you ok? Old Nov, please tell me a few words, my English is not good!"
"No wonder you have been flying airplanes for a long time. Teacher Wang asked you to learn, but you don't want to."
Zhang Peng looked at Galaktionov with a sad look on his face and said: "It's my fault. At first, I only had to memorize a few sentences and shout from a distance. Later, I joined the coalition government. There is no need to learn a translator.
…”
Mark didn't know how he got back into the cabin. The small Mars base suddenly became lively.
After taking a small earplug and putting it in his ear according to the instructions, Mark finally understood the words that made people cry.
"I said it's not easy for you to live here alone. Wait a minute and take our spaceship, and we'll send you back to Earth properly!"
Zhang Peng's carefree voice gave Mark the best comfort.
We can finally return to Earth! Although it is not the power of NASA, as long as we are people on Earth, we are one family.
Mark was not pretentious. After he was moved, he started to pack his things. The recorded video of life on Mars and the results of later experiments were imported into a USB flash drive and carried with him, and then he only carried a frozen potato seedling.
There are strict standards for the rocket's load. If there is one more person, Mark will have to throw away a lot of supplies. Life on Mars makes Mark feel that it is not easy. This dead potato seedling is his only thought.
However, Zhang Peng saw Mark's cautiousness and persuaded him: "Bring something else. It's so hard to come here. Why don't you bring some souvenirs back? If it weren't for the bureau's request, I would dig up a stone and take it back. Maybe
Being able to show off to that boy Peiqiang..."
Mark asked doubtfully: "Does it not matter the rocket's load?"
Zhang Peng squatted down and played with the potatoes in the box, and said carelessly: "Hey! What's the matter? Even if you take all these potatoes back, it will be fine. Your potatoes are growing very well..."
Suddenly Zhang Peng turned around, looked at someone in the crowd and asked: "Director, can we have potatoes and beef stew tonight? I haven't eaten the potatoes grown on Mars..."
