Tang Yue and Lao Mao sat opposite each other, with pen and paper between them.

Dim lights fell from the top of the head, shining on the faces of one person and one cat. Tang Yue was very serious, and the old cat was also very serious.

"Is it okay to completely cancel the intermediate orbit, abandon this 280-kilometer-high circular orbit, and only accelerate once, so that the Eagle spacecraft can jump directly from the parking orbit into the orbit of the space station for rendezvous and docking?"

"Okay, but the risk is very high."

“How big is the risk?”

"Jumping from an altitude of 280 kilometers to 380 kilometers requires an acceleration and a deceleration, which consumes a lot of propellant."

"Is there enough propellant left for us to try a few more rendezvous attempts?"

"Reiji."

"In other words, no matter what strategy we adopt, we can only meet and dock once in the end?"

"right."

"So which strategy ends up with more propellant left?"

"I need to calculate."

The old cat sat on the chair, closed his eyes, and began to meditate.

Then it started to smoke.

Half a minute later, the old cat opened his eyes, picked up a pen and paper, and began to write and draw, "If we abandon the original plan of two intermediate orbits and two orbit changes, and use the strategy of jumping directly into the orbit of the space station, then

We will be able to save 10% of propellant and four hours of time...but it is more difficult to jump directly into the orbit of the space station and requires remote guidance from the Kunlun Station."

"Ten percent propellant savings?"

"Ten percent."

Tang Yue immediately agreed, "That's it! This is Plan B! Let the lander jump directly over! Don't waste a second! Don't burn a milligram of fuel! Old cat, you will be responsible for the control and guidance! I will be responsible for helping you

Find the signal!”

Tang Yue inexplicably gained confidence and chose the plan very decisively. The old cat looked a little dazed and thought to himself, when did this sad dog become so hard-working? It didn't know where Tang Yue's excitement came from. This guy was in a few minutes.

I was clearly feeling disheartened and depressed before.

"We are already dead." Tang Yue said.

The old cat was stunned and didn't understand what this meant.

"We are already dead." Tang Yue repeated, "The launch of the Eagle spacecraft has failed, and Ophiopogon japonicus was undoubtedly dead... But God gave us another 2.477% chance. Can you understand?"

Old Mao immediately understood what Tang Yue meant.

They were never forced into a desperate situation.

But they were already in a desperate situation! Tang Yue and Lao Mao, from the moment the earth disappeared, were already fighting against the odds.

The failure of the Eagle spacecraft to enter orbit was supposed to be a 100% dead end, but a powerful rocket engine gave them the last glimmer of hope.

This is putting oneself to death in order to survive.

"When is the nearest orbit change window?" Tang Yue asked.

"The latest time window was five minutes ago." Old Cat glanced at the time, "The next time window is one hour and fifteen minutes later."

Tang Yue turned around and dragged up the Mingguang Armor outer suit, "I'll get you an antenna. Leave the signal problem to me. I will let you contact the lander before the next orbit change window comes! You go and drive that violent Maozi."

Space tractor, give it a super big drift at apogee! I believe in your driving skills... Akinayama stroller car god!"

"Don't worry! I will also drive the tractor for you like a Lamborghini! Look at how I reverse the truck perfectly into the garage!" The old cat gave a thumbs up, "Good Luck!"

Tang Yue put on the Mingguang Armor, picked up the antenna, strode out, and shouted: "Dear Comrade RD-0172! Although the country is big, we can't take another step back! Because behind us is Moscow! Ula——!

"

The old cat watched him bend down and get into the airlock, and suddenly realized that he was right that he thought Tang Yue's back looked like a bear. He not only looked like a bear, but also a furry bear.

Tang Yue's inexplicable confidence may not only come from his awareness of risking his own life but also the Russian text on the RD-0172 engine.

Immediately afterwards, a loud roar came from the airlock.

"Vodka! Davarisi—!"

"Dear Mom and Dad, I am Maidong. I am writing this letter to you on the Mars United Space Station. I am fine here..."

Maidong was stunned, and then pressed the backspace key to delete all the words.

"Dear Mom and Dad, I am Maidong. When I wrote this letter, the sun had just risen from the other side of Mars. The golden sunlight illuminated half of the Crystal cabin. The scenery here is really beautiful.

ah……"

Maidong shook his head and deleted all the words he wrote again.

"Dear Mom and Dad, I am Ophiopogon japonicus, are you okay? I'm going to die soon..."

Delete again.

"Dear Mom and Dad, I am Maidong, and I will go to your place soon..."

Delete again.

Maidong typed and deleted over and over again. She felt that every sentence she wrote was inappropriate, from the beginning to the end.

The girl's slender fingers finally stopped on the keyboard, and she fell into a long silence. Her mind was clearly full of what she wanted to say, but when she really wanted to start writing, she was at a loss and didn't know where to start. This is just like you

I was full of words and wanted to talk to someone. I raised my head and looked around, but suddenly I found that the world was vast and I was alone.

Maidong was sitting on a chair with a seat belt on her body. She was staring straight at the computer screen, the cursor flashing every second.

Maidong has written many articles since she was a child, and writing has always been her strong point. But here, this girl has never written a suicide note, and she has never tried to leave a suicide note to the deceased. The earth has disappeared, and her parents, family, and friends

Her colleague is long gone. If she writes a suicide note here, who can she leave it to?

But she still wants to leave something to the world.

Mai Dong didn't know if Tang Yue and Lao Mao could really make the Eagle spacecraft successfully deliver supplies, but at the moment a sandstorm was breaking out at the Kunlun Station and communication was interrupted. Even if Mai Dong was not a professional flight expert, she knew how difficult it would be. Success

The hope is very slim. If the Eagle spacecraft fails to rendezvous and dock with the Joint Space Station, then she will be dead.

Maidong had to finish this while he still had a little strength to write a letter completely.

But after writing, where should you send the letter?

Maidong's eyes fell on the control panel, densely packed with complicated buttons and switches.

Use the communication system on the space station to convert this letter into an electromagnetic signal and send it to the vast deep space?

Just like the last cry of the last person in the universe, Maidong doesn't know how far the radio waves emitted by the space station can travel. Due to the existence of the interstellar extinction effect, the cosmic dust permeating the vacuum absorbs electromagnetic radiation, and the radio waves will

The attenuation accelerates as the distance increases, and finally weakens to the point where it cannot carry any information.

But this distance must be very, very long. This lonely beam of radio waves will carry the girl's last words and fly in the vast vacuum for hundreds of millions of years.

Just thinking about it makes me feel lonely.

If there is anything in this world that is the loneliest, then it must be the last radio wave sent by human beings, carrying a language that no one in the universe can understand, from birth to death, running towards an endless distance.

So leave this letter on the space station?

A few years after his death, the United Space Station ran out of life and crashed into the atmosphere, letting the letters burn along with the space station, turning into ashes and spreading on the vast plains of Mars?

Maidong sighed quietly and hugged himself tightly.

As the last person on the joint space station, she wanted to write a letter, but she didn't know who to leave the letter to.
Chapter completed!
