It's not time for you to actually die...... You never know what death is.

This is what Tang Yue, a crow's mouth, told Mai Dong before the launch, in the center of Jiuquan on the earth.

Mai Dong nodded very sincerely at that time, although she didn't understand what this meant, she still took it as a warning from her predecessors to herself, and kept it in her heart.

Although Tang Yue just wanted to pretend to be forced at that time.

At this moment, Mai Dong stretched out his hand, as if he could touch death.

The golden sunlight fell on the girl's fair cheeks, moving slowly at a speed almost visible to the naked eye, and death turned out to be as silent, as soft, as silent as the sun.

Mai Dong looked up at the porthole, in the core cabin of the Crystal, she could see the stout and huge frame crossing her head, like the boom of a super tower crane, all kinds of complex and rugged machinery attached to the frame, those twisted and knotted parts exposed in the vacuum, they are clearly the cutting-edge technology of the 21st century, but it gives people a retro feeling like the crankshaft of a steam engine in the 19th century.

In the distance, wide solar panels are lined up in a row, like rows of huge paddles on ancient warships, deflecting with the sunlight and casting huge shadows on the white bulkheads.

This is the Mars Joint Space Station.

100 million kilometers from the Earth.

Alone in the universe 100 million kilometers away, the girl is probably the farthest wanderer from home in human history, and homeless.

Just five days ago, her life wasn't like this.

Mai Dong is only 25 years old this year, graduated from Zhejiang University with a bachelor's degree, and just got her master's degree from the Chinese Academy of Sciences before leaving Earth.

Before applying for a PhD, her supervisor suggested that she try to participate in the Mars exploration mission, taking the most popular long-term space-related technology as her research direction, and taking it as the research topic for her doctoral degree. With the gradual deepening of the Mars exploration project, many problems in long-term and ultra-long-term space missions have been exposed on a large scale, and have become a popular research direction in aerospace medicine, physiology and other disciplines.

This is somewhat similar to the Apollo program of the last century, a huge space program with a huge cost that can lead to the progress of many research and industries in the country and around the world.

The four major sinkholes of biochemical ring materials are very excited.

Mai Dong's research direction is the ecological cycle in microgravity confined space, which is a topic that involves a lot, very difficult, but of great significance, there are not many people in China to do this direction, Mai Dong hopes to make results.

To be honest, she didn't have to suffer this hardship, participating in the Mars expedition mission is extremely dangerous, the conditions are difficult, flying into space looks romantic at first glance, but life is extremely boring as soon as the freshness is over, and it takes at least two years to go back and forth, and it is like going to prison for two years to completely detach from society, for a young girl, it is simply a waste of life.

Mai Dong has so many senior sisters, junior sisters, senior brothers and younger brothers, no one has ever thought of going to Mars, everyone chooses simple and easy topics, ready to send articles to brush the impact factor, mix a diploma and graduate, who would be so stupid? It's a good and comfortable life, but risking your life to run to Mars, where birds don't? What if something happens to the spaceship and you can't come back?

Dedicated to research?

You're so noble, why don't you go?

In the end, Mai Dong was the only one who stupidly contacted the Jiuquan Center and participated in the selection and training.

This cute and simple girl passed the assessment with great tenacity and superhuman perseverance, and was successfully selected into the team of this batch of Mars expeditions and became Tang Yue's colleague.

The moment he learned that he was selected, Mai Dong was really happy.

She was given a small area on Orion and the Union space station to house her incubator, which contained a batch of plant seeds.

During the six months that the Orion spacecraft traveled to Mars, Mai Dong tended to these fragile plant seeds, watching them take root, grow and bloom, and reproduce from generation to generation.

Mai Dong's original plan was to use the collected data to complete the dissertation after returning from the Mars mission, and then apply for a doctorate.

If nothing else, half a year later, Mai Dong will return to Earth, get his degree smoothly, and graduate with a doctorate happily.

How wonderful.

Mai Dong gently put her hand on the keyboard and began to type, and she wrote out the title.

"Dear Miss Mai Dong......"

She eventually decided to write the letter to herself.

Since this letter has nowhere to go, it is better to write it to yourself, this is a suicide note that you left for yourself.

"Dear Miss Mai Dong,

Good morning, this is the eleventh sunrise today, the sun is shining, life is beautiful, but the stomach is very hungry, and the piano song "The Sound of Silence" is playing in the space station......"

Mai Dong raised his head, and the glass porthole reflected the girl's pale and thin face, and a pair of big dark eyes were very clear.

She smiled, imagining that behind the porthole was another self, and she was writing a letter to Mai Dong behind the glass, and that Mai Dong was also writing to herself.

“…… I've always known you're a smart and beautiful girl, and seriously, I've never met a better peer than you, perfect in every way, better than everyone else around me - a big cut. ”

The girl smiled playfully, a little weak-hearted, the text was a little narcissistic, but since it was written to herself, she didn't mind praising herself a few more sentences.

“…… The space station is still unable to contact Kunlun Station, the sandstorm is still continuing, I am very worried about Mr. Tang Yue and Mr. Cat, I don't know what happened to them? Was the Eagle spacecraft launched successfully? Regardless of the final outcome of the plan, I hope they can live safe and sound, Mr. Tang Yue is a good person, and Mr. Cat is also a good person...... Good cats, they all take good care of me. ”

Mai Dong paused.

“…… I am 100 million kilometers away, the universe is really unimaginably big, Mr. Carl Sagan once said: we are all stardust, at this moment you live, it is an incredible thing. You live on this planet, breathe its air, drink its fresh water, enjoy the warmth of the star closest to us, and your genes are passed down from generation to generation.

Going back in time, every cell in your body, all the elements that make up it, was born in the great melting pot of a star. ”

Mai Dong wrote word by word, time slipped quietly through the girl's fingers, the space station circled the far side of Mars, the sun set again, and the horizon of Mars rose like a huge mountain.

The girl let out a faint sigh.

"The sun has gone down again, and in an hour it will rise again......

Dearest Miss Mai Dong.

The universe is infinite and time is infinite.

In this vast space and long time, it is the greatest and greatest luck in my life to be able to share a life with you. ”
