The International Space Station, after the launch of the first component in 1998, the Dawning functional cargo module, successively added a number of components, and finally reached 15 pressurized modules, plus trusses, 4 large solar cell wings, and a bunch of big guys composed of human science miracles, the total mass of the equipment reached an unprecedented 400 tons.

This huge man-made device has been operating in space for almost 20 years, and it will be retired in two years because of the aging of the capsule and many problems between the components.

Once the International Space Station is scrapped and burned down, there will be only one country in outer space, the Tiangong space station, operating in low-earth orbit.

Generally speaking, this big guy of about 400 tons will circle the earth in an hour and a half, and there are only three astronauts stationed on the station every day, which has increased to 5 this time, including a geological expert, but the remaining four experts have not survived the catastrophe of the past few days.

Nina didn't know why she was the only one who survived.

The International Space Station became a huge nuclear fuel substance, and high-energy radiation filled each capsule.

Nina had smashed all the Geiger counters in the cabin, or the devices would have been ringing all the time.

In the service module of the "Star" on the International Space Station, the control panel kept flashing warning signs and screaming "Lethal radiation!" Lethal radiation! She can't turn it off even if she wants to.

Nina recorded alone on the International Space Station.

"An unknown disaster occurred in the universe, and 48 hours later, the structure of the space station was abnormal, 80% of the oxygen leaked, the pressure in the cabin was less than one atmosphere, and the radiation concentration was rising rapidly."

"Mike, a French astrophysicist and materials scientist, has discovered that the materials on the space station have undergone abnormal changes, and the iron element has begun to become extremely radioactive! According to Mike's measurement, the half-life of iron radioactive elements is only about 10 years, but the peak period will last for a long time, and the metal stress and strength have decreased significantly, and the hardness of titanium-iron alloy can no longer support the operation of the space station. They all died of massive bleeding after several hours of intense radiation! ”

At this, Nina burst into tears.

As the youngest astronaut ever in human history, Nina is only 23 years old, but she has already earned doctorates from many of the highest universities in the United States and Europe.

In the field of space physics, he has taken over the mantle of Hawking!

This time she went to the International Space Station for a 200-day mission, and she never thought that she would die alone in the harsh environment of the space station, which was radiated, hypoxic, and lacked materials.

……

"This may be the last time I send data, the space station won't last long, and the instruments have recorded drastic changes on Mars, observations indicate a huge starquake on Mars, etc., I just received a video signal from Curiosity, oh my!"

Nina looked at the final image coming from Mars, and the little girl in the spacesuit was stunned.

"I will start sending this video message in real time immediately, I don't know if anyone on the earth can receive this data, the space station is running out of power, I will use the clear code to send it to the world, NASA!"

Wearing a spacesuit, Nina was inconvenient to operate.

Without the slightest hesitation, she took off her thick spacesuit in the cold, energy-starved space station laboratory.

For a moment, she felt countless tiny high-energy particles on her skin hitting her like raindrops, making her life come to an end quickly.

She couldn't care about any of this anymore, so she only wore thin underwear and started operating the computer, concentrating the last power of the space station and sending it to the world!

Ten minutes later.

"God willing!" Nina curled up hard, waiting for the final moment of death.

On the communication station, a small light is flashing.

Nina glanced at an unknown source requesting a call, and a flame of hope burned in Nina's heart, and her heart cheered, "Is it Houston?" ”

When the channel was opened, an unfamiliar voice sounded, speaking in Huaxia, which she couldn't understand.

"Oh, well, can you hear me? Can you hear me? I'm the earth, the earth over there, can you hear me? ”

Nina grabbed the microphone and shouted in English, "I can hear you, I don't understand what you're saying, can you speak English?" Answer me! ”

"Oh, Saorui, Saorui, I forgot in a hurry, I'll see where the automatic translation module is, military computers don't have this function? I'll write one myself, wait a minute...... Werther, ah, three Kende (Wait a second! The unfamiliar voice spoke authentic Northwest English, and Nina's brain was a piece of mush.

After waiting for a few minutes, the voice continued to sound.

"Okay, got it this time, right? (English)", this time the voice was a little weird, with a serious sense of mechanics, but Nina finally understood.

"I'm the International Space Station, I'm Nina, Nina Hamilton, I need rescue, please, help me", five days without talking to anyone, Nina is going crazy.

"Don't cry, I want to bring you down, but I don't have rockets or spaceships at hand, but you can get down by yourself! Do you know that there was a cow fork movie a few years ago, have you seen it? (English)"

“？” Nina was dumbfounded.

"Gravity!" This sentence is repeated twice in Huaxia and English.

Nina is completely insane.

"Look at what scares you, my return plan has been calculated by the best laptop in Huaxia, and it is the most effective, rest assured (English)", in the voice of the call, the strange male voice conveyed that he was full of indifference and confident.

Nina stayed in the cold service module of the International Space Station "Star" for a long time, wiping a cold sweat, she didn't know what to say.

The service pod began to receive data, a TXT document, a jumble of wrong words, an inverted grammatical structure, costing Nina many, many brain cells.

After reading this Chinese man's plan, the only feeling in Nina's heart was that this Chinese man on the ground was teasing her?

"Is it a Chinese astronomy enthusiast? Assembled an antenna device yourself, so you kidding me? ”

The radio was still on, and the man's voice came out, "Hello, hello, are you still there?" I forgot to turn on the translator again, Werther, Werther, wait, outside, outside, there, monster, monster, I'll fight the monster first, we'll talk later. ”

The radio was silent.

So, Nina floated to the material warehouse, rummaged through the boxes and cabinets, scooped out a bag of tomatoes, and bit down to suppress the shock.

Nina is alone in space, more than 400 kilometers above the surface of the earth, and it is a little messy.

As she drifted back into the command module, she began to feel unreliable.

Nina thought about it, or should she ask the ground command center first, in case they troubleshoot?

Floated back to the command cabin and turned on the communication equipment, "Call Houston, call Houston, call Korolev, Korolev!" ”

Once again, the International Space Station has flown into the dark side of the planet.

The radio was silent.

Outside the small porthole was an absolute dark shadow.

……

Nina has always loved to see the night view of the earth.

Looking from the space station, entering the earth in the middle of the night, the light strip of the human city always makes the dark side of the planet, full of fantasy and warm light, and the bright city makes the space station flying at night no longer lonely, so that she will not feel lonely and lonely.

However, 6 days ago, there was no light to be seen on the dark side of the earth, and the light of civilization disappeared overnight, leaving the earth in its purest darkness.

Outside the small porthole, Nina could not see the continents and oceans on the earth, as if humans had never existed on this planet.

In the silence, the radio sounded again.

"It's back, it's back, on the way to send the panda just now, a large number of monsters appeared, some trouble, panda you know, Panda, Panda! It's far away, now listen to my plan. (English)! ”

Nina resigned to her fate, "Alpha (ISS codename) received, please identify yourself!" ”

Although she didn't know how this strange man got in touch with the space station. But his ability to connect to the space station at any time during operation shows that this man is not joking! Because if he had only sent a command from a location on the ground, the space station would have flown to the other side of the earth in an instant! After flying at high speed, he can't connect to the signal, so he has to have a communication network across the earth to do so.

"Me? Oh, forgot to introduce, my name is Jiayu, which translates to good fish? Forget it, just put it ...... I am an evolutionary in Qingcheng, N Province, northern China, and I am also an astronomy enthusiast, and "Gravity" is my favorite movie to watch......"

Nina's brain is a little insufficient, is there already such advanced technology on Earth? An astronomy enthusiast from a country on Earth casually cracked the key to the communication satellites of dozens of countries and contacted the space station?

What is an Evolutionary? Let's eat another tomato to crush the shock......

"The movie "Gravity" is good, but it's a little unrealistic, if you return to Earth, you can't do that, what about the return capsule? (English)" The male voice insisted on talking to himself, regardless of whether Nina agreed or not.

"I have to wait here, waiting for the ground command ......," Nina replied with some hesitation.

"Waiting for instructions? Got water in your brain? You've been shouting for three days, no, you've been shouting for six days, is there a fart on the ground? ”

"Let me tell you, the Baikonur Space Center in Russia has been reduced to rubble under a volcano, and the Korolev Ground Flight Command Center has been buried 15 kilometers underground in the earthquake! Your country's Houston ground command center has been affected by the great tear in the San Andres fault zone, and all the equipment is finished, and I am your only chance! ”

Nina was stunned.

As if she had given up all hopes, this time she began to break the jar, "The return capsule and the three laboratories have exploded and cannot be entered, and the other equipment is basically normal, what should I do?" ”

"Following what I just said, "Gravity" is a good movie, and finally relied on our Tiangong in Huaxia to go back to Earth, but the Tiangong space station in Huaxia has just started to be built now, only Tiangong-2, Tianzhou-1 has not yet had time to launch, and the Shenzhou spacecraft is also waiting, and it will be in vain to go......"

"Besides, you don't have any equipment to fly over, I know, your little chair for spacewalking will run out of power in twenty minutes, and you won't be able to reach Tiangong!"

The man seemed to be thinking, and Nina waited for his answer.

"Now there's only one way, and that's to build a return capsule yourself!"
