Today is Tang Yue's fifth day of being trapped on Mars.

He didn't have time to care about whether the earth appeared today, according to the plan, the Eagle spacecraft would be launched in the next twelve hours, and the old cat asked him to rest, after all, Tang Yue had been working for more than ten hours in a row, but the cargo lay on its stomach in the living compartment for half an hour and came out again.

"Aren't you going back to rest?" The old cat is adjusting the computer in Kunlun Station, and the old charging cable is still dragging behind his buttocks.

"I've rested enough."

"You're not afraid of sudden death?"

"Wait for the Eagle spacecraft to be successfully launched, and then die suddenly." Tang Yue was wearing a pair of pants and wrapped in a thermal blanket, "Then I will die as I deserve." ”

The time at this moment is 4:55 a.m. on August 16, 2052 in the Earth calendar.

Outdoor wind speed is 39 meters per second.

Tang Yue stood on the edge of the porthole, opened the lid and lifted it, squinted his eyes and glanced out, frowning, the sandstorm was raging, and the night was dark and the wind was high.

As the night passed, the wind speed rose from 35 meters per second to 39 meters per second. The sandstorm is the first hurdle that the Eagle spacecraft needs to pass, if the wind speed cannot be lowered, then the lander will not be able to take off safely, and the subsequent orbit, rendezvous and docking will not be able to talk about.

"If you don't sleep, then come and help me out." The old cat left his seat and gestured to the chair in front of the workbench, "Sit here." ”

Tang Yue stood on the side with a glass of water, munching on bread, stunned for a moment.

"How can I help?"

Tang Yue walked over and put the water cup on the table, with bread in his mouth, and then sat down on the chair.

"The system computer is being self-tested and tested, you help me look at the point, notify me in time if there is a problem, and then stare at the wind speed......" The old cat turned around and took off the cabin suit from the wall, unzipped it and drilled in.

The old cat was silent for a few seconds.

"Tang Yue, help me take a look, why can't the zipper of the spacesuit be closed?"

Tang Yue turned his head and glanced at it.

"Because your charging cable wasn't unplugged."

Old Cat: ......

It's so charged and so forgetful.

Tang Yue bent down and leaned over to help the old cat pull out the charging cable, zip it up, and then put the helmet on it, "Are you going out?" What are you going to do? ”

"Go to the Eagle spacecraft for one last routine inspection before launch." The old cat buckled up his helmet to make sure there was no problem with the airtightness, and then locked the safety rope to his spacesuit, "I need to turn on all the systems of the lander and keep it on ready for launch." ”

Tang Yue nodded, "When can you come back?" ”

"An hour and a half at most."

"If you don't come back for an hour and a half, then I'll take back the safety rope." Tang Yue said, "Pay attention to safety. ”

The old cat nodded, dragged the safety rope to open the hatch of the airlock room, Tang Yue returned to the workbench, green numbers and graphics flashed on the computer screen, several sine waves of different colors moved slowly in a chart, and the dense parameters changed accordingly, I don't know what software this is running, and I don't know what it is doing, anyway, Tang Yue can't see it, in order to protect his eyes, he chooses to turn his head to look at the anemometer.

The number on the LCD screen is 38.89m/s.

38.89 meters.

The launch security line drawn by the old cat is 30 meters.

Nine meters.

As long as the wind speed drops by another nine meters, they will be able to launch the Eagle spacecraft.

The reduction of wind speed is the premise of all actions, and this is a condition factor that cannot be affected by manpower, and it can only be seen whether God appreciates the face...... Tang Yue sat on the chair and stared at the display results of the anemometer for a long time, as the minutes passed, the numbers on the anemometer occasionally beat, and Tang Yue's heart also beat violently.

His heart was very uneasy and nervous, every slight change in this number could affect Tang Yue's nerves, even if it was a change in a number of two decimal places, the wind speed decreased by 0.01 meters, which could surprise Tang Yue.

Descend! Descend! Tang Yue clenched his fists and said silently in his heart, I beg you to come down quickly! Come down, I'll erect a monument to you! Offering you up!

He knew that his prayers could not affect the climate on Mars at all, but when people were cornered, they always pinned their hopes on metaphysics.

38.24 meters.

Drop again! Push harder, go down a little more! Tang Yue roared silently in his heart, his mouth was dry, he was holding a water cup in his hand, but he forgot to drink water.

38.17 meters.

That's just a little bit close! That's just a little bit close! Descend a little further and you'll be able to break through the 38-meter mark! Tang Yue clenched his fists fiercely, his face was hideous, and he didn't know whether he was cheering up the anemometer or the wind speed.

38.02 meters.

Fall! Fall! Drop drop!

Tang Yue was almost about to shout, he saw hope, the Eagle spacecraft could be launched! Mai Dong is still saved! The wind speed is gradually decreasing! Although the drop is small, at least it is still falling, and as long as the wind speed is declining, there is still hope, and according to this trend, the wind speed will definitely drop below 30 meters per second!

He couldn't sit still any longer, got up and leaned on the table, staring at the scarlet number on the anemometer display.

You can do it!

You can do it! A little further down! Tang Yue clenched his fists and roared, you can do it! It was as if he was watching a snail race, and even though the snail was slow, as long as it kept running, it would definitely reach the finish line.

38.01 meters.

38.00 m.

It's done! It's done! Tang Yue is excited, the wind speed is about to break through the 38-meter mark!

The numbers are beating again.

41.25 meters.

Fall...... Tang Yue was stunned, he couldn't shout, all the strength in his body was instantly emptied, Tang Yue sat down on the chair weakly, his heart was empty, the wind speed rose back in an instant, and now it seems that the previous slight drop is not a precursor to a decrease in wind speed at all, but a normal fluctuation of wind changes, it drops from thirty-nine meters per second to thirty-eight meters, and then rises to forty-one meters, only floating up and down within this speed range, there is no intention to descend at all.

Then something even more terrible happened, and the anemometer measurements began to change continuously.

42.33 meters.

42.74 meters.

42.89 meters.

43.12 meters.

43.58 meters.

The wind speed soared all the way at an extremely fast speed, unstoppable, so fast that Tang Yue didn't have time to react at all, a series of continuous heavy blows shattered the little hope left in Tang Yue's heart, Tang Yue's whole brain was in a daze, he even wanted to get into the anemometer, use all his strength to climb this damn number, and use his strength to suppress its rising speed.

The wind speed finally stopped at a desperate 44.28 meters per second.

44.28。

Finished.

Tang Yue sat in the chair, he wanted to say something, but his throat was so dry that he couldn't make any sound.
