As soon as you get off the G1137 driving from Nanjing to Kunming, you immediately board a driverless electric car and head straight for a long-forgotten alley on Shulin Street in the old city.In this alley called "Smoke Alley", there is a Chongqing hot pot restaurant.This small hot pot restaurant has to "crash" every time to clean up, in order to cope with the several surprise inspections in the past year.Only in this way can this small hot pot restaurant meet the minimum hygiene standards.

You originally wanted to eat fried dough sticks with bait at Jiekou, but you failed to do so.I heard from the owner of the hot pot restaurant that the aunt who sold the roasted bait cubes had already sent her son to college by selling this simple "roadside breakfast", earned three houses by the way, and rented out two of them.Neighbors and neighbors said that now she travels around the world or dances in the square every day.Do you still feel a little regretful about not eating the fried dough sticks with bait that you have been thinking about all this time?
Eating Chongqing hot pot in a small restaurant in Kunming where the greasy molar floor will make the soles of your shoes sizzle?Are you afraid that you will be laughed at by colleagues from Sichuan and Chongqing when you arrive in Jiuquan in a few days?Haha, if you tell your friends in these two places that you think the food here is more spicy than in the original place, I am afraid that when you work in the space station, they will deliberately turn off the exhaust fan when you have a haircut, so that you will be diffused Shall I play with broken hair?

I heard that the three of you went to someone else's hot pot restaurant at noon yesterday. The owner of the hot pot restaurant just woke up at noon and served you hot pot, and then continued to eat until those old night owl bosses yawned?You really have to be thankful that you were born seven or eighty years late as a professional astronaut.

When you are still 30 meters away from the small shop, you will see the sign that has been hanging for decades, which says "Dogs waste food!".You also agree with this sentence, don't you?Hahaha!After all, you know that even in this era, materials, food, and all kinds of things are already so abundant and so cheap, but cherishing food and taking every grain, piece of meat, and leaf of vegetable seriously is still very precious virtue.

You should know that those old aerospace predecessors were not allowed to eat such spicy things for a long time before and after their missions.And you and many of your colleagues are still overeating such oily, spicy and salty food less than a month before the launch.If it wasn't for the aerospace test that proved that you don't have any psychological dependence on bridge rice noodles like many of your fellow villagers, you probably wouldn't be allowed to enter this mission.

But what makes others jealous and makes yourself a little proud is that you have eaten in a place like Kunming for 16 years, and when you were studying in the Department of Astronomy at Nantah University, you spent 12 years eating and drinking in the Yangtze River Delta with a scholarship. Able to maintain the physiological indicators required by space workers...

Today, on the G2283 high-speed railway from Kunming to Chengdu, you chatted happily and energetically with those two guys who study synthetic biology and biomedicine at Yunda University?But think about half a year later, even if they work in the L3 Tiangong space station on the earth, there will be at least a ten-minute delay in sending messages back and forth, and there will be at least a hundred pairs of eyes and a hundred pairs of ears watching these messages. Are you calling A little shiver?
After arriving at CASC Chengdu Station, the three of you actually declined the invitation to eat hot pot from Xiao Wang, the receptionist specially sent to guide you.But you should still firmly believe that the canned black tea that you brought with you before getting on the car today is still very popular with everyone.

The 87 bioengineers, astronomical observation experts, space station paid travelers, and changing guards who set off in the same batch gathered at the isolation and adaptation center of the Jiuquan Launch Center. The main goal in the next month is to make your already healthy body better. Quickly adapt to the work of the Earth L3 space station, the Mars L1 space station and the asteroid belt space station.You have to be mentally prepared. I heard that this month will be really, really, really hard.

In the past month, your rookie class has been so messed up by three regular astronaut training instructors that you don't even have the energy to write a diary, right?But later, when you heard that you only did 15.00% intensity and less than [-]% subjects for regular astronauts with military backgrounds, did you admire professional astronauts even more?Those two Yunda men seem to be inferior to you in terms of endurance?You guessed that it should be due to their moderate-intensity exercise for about ten hours a week at the Haigeng base. After squinting your eyes and inquiring, you learned that the unshakable [-] hours of physical training every week made you a little dizzy. one time?

I'm leaving tomorrow, I know you still have a lot of regrets.It seems that you need to say goodbye to the food that is not suitable for eating in space more than a month ago, that is, the food that will not be available in the space station for the next 100 years, for at least five years.The people at China Aerospace are really careful. Knowing that you have the habit of writing diaries on paper with a pen, they distributed a box of supercharged refills with three colors of black, blue and red, which can write [-] kilometers. Ballpoint pen for you.Although you know that this is the duty of the staff, the heart represented by each can of black tea should still make them leave a good impression on you.

It's been a few days since you arrived at the Tiangong-1 space station. Although you know the exact time when the Chaohu supply shuttle will leave here and fly to the Optical, even Mr. Sun from the navigation department can tell that you don't want to stay here for one more minute. .Because you failed to take the solar eclipse observation ship from Deseado Port to Accra in March next year, you missed the opportunity to experience the seven-minute total solar eclipse from the perspective of a witness, and then you may apply Do you feel anxious and depressed when you miss the opportunity to observe this solar eclipse outside the Earth-Sun-Moon system without the observation time for this common astronomical phenomenon in the solar system?It is also because all points A to B of the space station are connected in the most recent and concise way. This kind of form that others think is full of industrial style aesthetics made you draw lines and color blocks for several years following the online training class in elementary school. People who boast a bit of artistic ability feel that they have no sense of beauty?Really boring...

You can't believe that CASC didn't deliberately arrange the time, so that you, a person who works at a place 1000 million kilometers away from the earth when you first go into space, can wake up in a semi-trance state on the third day after voyaging for more than 100 days. During the recovery process, I had a video call with my family on the first day of the new year.Although the delay of more than seven minutes in the communication added some slight headaches to the trance of waking up, the two hours of communication with family members must still make you feel happy and comfortable, and there are some benefits to the organization. move.You still have to cheer up, there are another 48 hours, and the official work will start on the third day of the Lunar New Year.

You should be familiar with this observation space station, right?Your supervisor, Professor Li, and several NTU observational astronomy authorities participated in the design of the observation space station group. You have also done some related projects in the past few years, right?The inhabited area of ​​this space station is very advanced. It uses the centrifugal force generated by the spin to simulate gravity. This artificial gravity is slightly higher than that of Mars, about 50.00% of the earth's gravity.Such working conditions should save you from exercising as hard as Mars workstations or many small low-Earth orbiters.They maintain a lot of exercise every week to ensure that the impact of microgravity on their bodies will not burden their daily work.

Speaking of which, when designing this space station, you are preparing for the college entrance examination and repeatedly brushing questions every day, while the upsurge of cheers for the establishment of the permanent Mars base, legends made out of nothing, and some lace news are still being ignored in the public media. Repeat the hype.When Professor Li later gave you a lecture on Observational Astronomy in the Second Research Institute, he also lamented that this construction operation has improved hundreds of times compared to the arguing between major countries when the International Space Station was postponed more than 40 years ago.

He said that at that time, they took off from seven major launch sites around the world, each carrying 97 large-scale industrial ice sculpture machines, and headed towards Ceres, Eris, and Haumea, asteroids with solid water.In the next 11 years, they will send more than [-] cubic kilometers of carved ice components to the three assembly nodes. In the vast space of the asteroid belt and Mars orbit, they will assemble three [-]-kilometer-diameter The main objective lens of the Newton-class space telescope.These largest astronomical telescopes in history will increase the breadth and precision of human optical observations of deep space by hundreds of thousands of times compared with the equipment on the earth and near earth orbit at that time, which is a scientific project with epoch-making significance.Of course you also believe in this, after all, the power of science, data, facts, and experience is so powerful here.

The news you received half an hour ago made your stomach cramp until now. Fortunately, the previous observer on your rotation repaired the negative pressure washbasin she broke. Otherwise, the vomit in this half hour may have given you several headaches God.After throwing up all the food you've eaten in the past fifteen hours, you're probably going to tear up the rest of your grief, wondering what the news will look like when it's fully announced on Earth in a month's time.

Can you accept this cruel and weird fact?This asteroid, which may be the most important astronomical discovery in the history of mankind, and may at the same time press down the countdown to the extinction of mankind, is actually a person like you who has just obtained a doctorate, worked in space for the first time, and applied for the optical number for the first time. The observation time was only discovered by a short-haired female observational astronomer who had only talked about two boyfriends in the past 30 years?

Gu Lanlan, Gu Lanlan, you actually want to leave your name in history in such a way, what will those elders who are still on earth think if they find out? !

Shouldn't you, as a well-trained observational astronomer, do more work in your limited life on this extinct asteroid that you discovered and may be named after you?Fear and ignorance of the universe can certainly break people and their will, but sometimes, they can also enable people to exert their greatest wisdom and tenacity. These two ultimate weapons that have been tried and tested in human history , I hope you and your descendants can solve this problem within 300 years.

This morning, at 300:[-] Earth Standard Time, you declined the offer of the International Asteroid Committee to name this ominous celestial body after your name "Gu Lanlan". Mars will be smashed in a few kilometers", "What is the probability that Gu Lanlan's fragments will hit the earth after colliding with Mars", after all, it is not a good thing to forcibly associate one's name with a disaster.

It is really luck and coincidence, you were approved on March 25th to have 27 minutes of observation time after orbit change and angle adjustment on March 170th, to conduct routine research on the Doradus Nebula 17 light-years away, And you find unusual transits and blueshifts the next day while collating data and images.After you reported to the International Astronomical Union, two other Newton-class telescope space stations joined the observations, and supported by microgravity measurements, more detailed spectroscopy, and direct imaging evidence in the ensuing week, the Union obtained the following disturbing results :
1. The asteroid numbered 2973161 is the ejecta of a type II-P supernova explosion 17 years ago, [-] light-years away from the solar system;

2. The diameter of the asteroid is 4000 kilometers, the mass is 90.00 billion tons, and the material composition is 56% nine is iron-[-];

3. The asteroid is moving at the initial speed of the supernova explosion 17 years ago. After several unknown decelerations, it is currently flying towards the solar system at a speed of one thousandth of the speed of light, that is, [-] kilometers per second;

4. In the past 17 years, the asteroid's orbit has shifted due to passing through several massive celestial bodies, causing its ultimate goal to be Mars in the solar system;
5，小行星与火星的正面碰撞将在地球标准时间2381年七月29日下午十七时23分37秒发生，届时火星将因为撞击解体；

6. The fragments of Mars disintegration will move towards the inner solar system at a speed of not less than ten kilometers per second, and there will be a 17.00% chance of hitting the Earth, an 11.00% chance of hitting Venus, and a [-]% chance of hitting Mercury , the fragments that have not collided with these planets will eventually be swallowed by the sun's gravity;

7. The destructive power of those Martian fragments that hit the earth will be no less than that of the asteroid impact that wiped out the dinosaurs at the end of the Cretaceous period 500 million years ago.

It seems that everything depends on what human beings do in the next 200 years...Hey...the chemical elements in the body that produce emotional power must have overcome those trivial rational considerations. You report to CASC and ask you to work more here Two years, although discovering that asteroid does not make you an expert on it, but since you are here, do as much as you can for yourself.

At the very least, you've got to try to do something so that the next 300 years of good-natured and obnoxious scumbags will put "Retribution Angel", "Doom Queen", "Speaker of Evil" around your name The title of the class.

Note: This diary holographic photocopy is included in the main text entry of "The History of Human Universe Development". It is a holographic photocopy of at least tens of thousands of paper diaries included in the "History of Development". museum city.In order to commemorate this ancient Chinese observational astronomer named Gu Lanlan who may have been unknown for a lifetime, but was engraved in the annals of history because of the discovery of asteroid 2973161.

After she discovered the asteroid, she has been applying to work on the Optics and never left. Her persistence and professionalism have always allowed the relevant agencies to approve her request until 53 years later because of common astronauts such as osteoporosis and muscle atrophy. Illness, together with anxiety and grief, hastened her life and passed away.

In these days, she seems to be over-consuming her life to study all the knowledge related to asteroids, maybe this is one of the reasons why she died at the age of 81, when the average life expectancy of a normal healthy human being can easily Cross the 100-year line.

The author excerpts here the text of her diary two months before and after the discovery of the asteroid, expressing her feelings for the time point that changed the overall development trajectory of mankind since then.Although, at her own request, she will not name any newly discovered natural celestial bodies or newly created artificial celestial bodies in the future, but her name, more than 3000 years later, is inhabited across hundreds of thousands of light-years. The place is still known to women and children.Perhaps, this is also the best consolation for this dedicated scientist.
