Mars is the fourth closest planet to the Sun.

Its orange-red appearance is due to the fact that the surface of the Earth is covered with hematite (iron oxide), Mars is about half the diameter of the Earth, and the inclination and rotation period of the axis of rotation are similar to those of the Earth.

Since the beginning of aerospace development, Mars has been a second home that humanity has aspired to transform.

NASA's Ares 3 exploration project sent a small team of scientists to Mars to begin preliminary research.

Mark Watney's work as a botanist with a focus on water temperature and soil science and environmental science will be key to whether humans can complete plant cultivation and obtain stable food.

But after 135 days on Mars, Mark Watney was not in a good mood. Because his teammates left him on Mars on the eighteenth day of the research mission.

On the eighteenth day of the mission, he and five other astronauts were confronted with a giant storm that ended their journey into outer space early.

He was left on Mars because he was mistaken for not surviving, becoming Space Robinson.

Like Robinson, he had the supplies left over from the entire ship, but they could only support him for more than ninety days.

Mark did everything a botanist could do, making fertilizer from the poop he and his teammates left behind, making oxygen and water from rocket fuel, and successfully breeding potatoes on Mars.

If the plan goes well, he can return to Earth in the next Homan transfer window.

But this is when the plan goes well, and he will survive on Mars alone for 868 days, along 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 inspect his potato cultivation bin, the isolation material was broken, causing the cultivation bin to lose pressure.

The plants died, and the total loss of pressure caused the water in the plants and the surrounding area to vaporize, and the bacteria that were fortunate enough to be used as fertilizer in the poop also died in the sub-zero temperatures of Mars.

Without the breeding bin, Mark could no longer plant, so he could only eat his remaining potatoes and strictly follow the rationing system to survive until the 609th Martian day.

And the next spacecraft rescue will require 868 days on Mars, and dying on Mars has become a foregone conclusion.

And launching a rocket from Earth to Mars takes 414 days of flight. The planet's efforts became key.

Mark can only pin his hopes on the efforts of the earth, and he can only take care of his wounds after cleaning up the plantation.

While talking to the monitor, Mark recorded his mental activities and life, which can be used as research materials for later generations, and can also be used as proof that he has lived.

While dealing with the injury at the corner of his eye, Mark said with a slight chatter: "On the 135th day, my cultivation warehouse exploded. I can only hope for the earth. I knew in my heart that I had done everything I could, and I hoped that the Goddess had given up on me. ”

With a self-deprecating laugh, Mark continued: "I don't know if it's a hallucination, but when I recognize the reality, I can already feel the death knocking on the door, just like the loneliness of flying alone on the space station, and I feel like someone is knocking on your cabin door......"

"It's like this......"

Mark tapped on the table as he spoke, the sound of the bang gradually overlapping with the sound he 'heard'.

With a swipe, Mark bounced and yelled, "It's not an illusion!" Something is really knocking on the door! ”

But this is on Mars! Mars without life! How could anyone knock on his hatch!

Frightened, Mark quickly got on board his Martian protective suit, and the weak protection provided by the protective suit gave Mark some confidence.

Trembling at the hatch, Mark did hear the knocking outside.

'Tom~Tom~Tom~'

Regular, rhythmic, and even patient.

In order to ensure safety, the hatch of the Mars base is not designed with observation windows.

Mark can only do his mental construction through the hatch.

Things have gotten so bad, how bad can they be? Meet aliens?

Mark suddenly smiled when he thought of this. He turned on the camera on his suit and prepared to start recording.

After taking a deep breath, Mark began to adjust the pressure in the isolation chamber and opened the hatch.

"Oh mom, big brother, you've been thinking for a really long time!"

After Mark opened the hatch, before he could see his surroundings clearly, such a sentence appeared in his ears.

The atmospheric pressure of Mars is 500~700 Pa, and the density is less than one percent of that of Earth, but shouting at such a close distance allows Mark to successfully distinguish that this is the language of the Earth.

Relieved, Mark was in the mood to look around, a team of eleven. They all wore full-coverage spacesuits, which looked somewhat similar to those used on the space station, but the lightness was already beyond that of the space station spacesuit.

After all, an extravehicular spacesuit weighs 120 kilograms, and no one can wear it to keep knocking on the door after moving freely on Mars.

When Mark was stunned, a hand slipped in front of his eyes, and the person he had just communicated with was waving in front of his eyes, trying to awaken his consciousness.

“are you ok？ Old Noff to say a few words, I don't speak English well! ”

"No wonder you're a flyer when you're old, Teacher Wang asked you to learn, you don't want to."

Zhang Peng looked at Galaktyonov with an uncomfortable face, and said: "Blame me, I only had to remember two sentences at the beginning, just shout in the air, and then I joined the coalition government, and there is no need to learn the translator......"

Mark didn't know how to get back into the cabin, and the originally small Mars base was instantly lively.

When he took a small earbud and put it in his ear as instructed, Mark finally understood the crying words.

"I said it's not easy for you to live here alone, wait a while, take our spaceship, and we'll send you back to Earth properly!"

Zhang Peng's big grinning voice gave Mark the best comfort.

Finally able to return to Earth! Although it is not the power of NASA, as long as it is an earthling, it is a family.

Mark was not hypocritical, and after he was moved, he began to pack his things. The recorded video of his life on Mars and the results of the 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 load of rockets, and with him alone, I don't know how many materials to throw down. Life on Mars made Mark feel that this dead potato seedling was already his only thought.

However, Zhang Peng saw Mark's caution and persuaded him: "You bring something more, it's hard to come here, don't you bring some souvenirs back?" If it weren't for the bureau's request, I would have wanted to dig a stone and bring it back, maybe I could show off that kid Peiqiang......"

Mark asked suspiciously, "Doesn't it matter if the rocket load?" ”

Zhang Peng squatted down and fiddled with the potatoes in the box, and said with a big grin: "Hey! What's that. Even if you take all these potatoes with you. You're looking good at this potato......"

Suddenly, Zhang Peng turned around, looked at a person in the crowd and asked, "Director, can we eat potato and beef stew tonight?" I haven't eaten the potatoes grown on Mars yet......"
