Manned space flight is a round-trip flight activity in which humans drive and ride on manned spacecraft in space to conduct various exploration, research, testing, production and military applications. The purpose is to break through the barrier of the Earth's atmosphere and overcome the Earth's gravity, expand the scope of human activities from the Earth to space, fully understand the entire universe, and develop rich space resources.
This is a highly difficult system project that integrates the country's political, military, economic and technological strength. In order to complete this huge project, we must overcome three major technical difficulties.
The first is that we must have high-thrust launch vehicle technology to send very heavy spacecraft into low-Earth orbit. The second is satellite safe return technology. The third is a good environmental control and life support technology system. Each of these three points is crucial and indispensable.
All things are difficult at the beginning. The first step in building the Great Wall is also the most arduous. From the first day the plan was established, Su Qingyun became unprecedentedly busy. He wished he could run when walking, and he was even thinking while eating and sleeping. The researchers in the entire launch center were in almost the same state. But while they were busy, everyone also felt fulfilled and satisfied, because everyone's hearts were united, and they all had the same goals and ideals, and even their walks were like the wind.
In such busyness, the book of time turned another page and came to 1981.
Su Qingyun dragged her tired body out of the laboratory. She was extremely exhausted. The strong wind blew and she shivered with cold, and she quickly woke up.
She looked up at the sky in front of her and was stunned. The sky was dark, with a faint red glow. The visibility was extremely low, and the wind and sand blew into her mouth and nose. Su Qingyun was choked and coughed instantly. Her eyes were blurred and she could not open them. She could only lower her head to protect her mouth and nose.
"Researcher Su, why are you still here?" A voice came from the dimness, surprised and anxious. "A sandstorm is about to blow. Go back quickly and stay indoors. Don't come out!"
Su Qingyun couldn't see the face of the person who came, but he could tell from his voice that it was Brother Jiang, who was in charge of security at the launch center. He turned on the flashlight in one hand. Su Qingyun rubbed his eyes and shed emergency tears, and finally he could see things clearly.
"I just came out of the lab." Su Qingyun said with difficulty, "Why is there a sandstorm? What level is it?"
Su Qingyun has been in the launch center for almost two years and has experienced sandstorms before. This is a desert area, and sandstorms are not uncommon. However, there has never been a large-scale sandstorm like the one today that looks so powerful.
"The weather monitoring center said it's probably a sandstorm with wind speeds of level nine."
"What?!" Su Qingyun's face changed and his heart tightened.
A sandstorm with a wind speed of level nine is already a strong sandstorm. It is extremely harmful to life and production, not to mention their crucial launch center. Sandstorm weather will bring very serious consequences, can destroy many things, and is very destructive.
Su Qingyun only felt that the wind in front of her was getting stronger and stronger, with a momentum that could crush her to the ground. She was almost unable to stand, and Brother Jiang quickly supported her.
"Researcher Su, let's go, let's go inside quickly, otherwise the sandstorm will come and we won't be able to leave."
"Where are the others?" Su Qingyun asked.
"The other researchers are safe. Director Zhao didn't see you, so he asked me to come find you." Brother Jiang explained.
"That's good." Su Qingyun breathed a sigh of relief, then suddenly thought of something and his face changed drastically. "What about those test facilities and equipment?"
"What?" Brother Jiang didn't understand.
Su Qingyun didn't have time to explain in detail, he just ran away, feeling extremely anxious. Many of the test facilities and equipment in the launch center were placed in the open air at various locations. Once a sandstorm came, those launch towers, experimental workshops, radar antennas and other equipment and facilities would be very dangerous, and their previous efforts would be destroyed.
She ran in the wind and sand, unable to see the direction clearly. She could only run to the surrounding points based on the route she remembered. The anxiety in her heart made her unable to care about anything else.
"Researcher Su, don't run, it's dangerous!" Brother Jiang was also anxious and hurriedly chased after him with a flashlight.
When Su Qingyun arrived at the launch center, the wind and sand were getting stronger and stronger. The whistling sound was like the howling of ghosts and wolves, which made people panic. However, she didn't care about anything else. The only thing in her eyes was the radar antenna that was about to collapse. She ran over as fast as she could.
"Researcher Su, it's dangerous!" Brother Jiang was so scared when he saw her running over to hold the radar antenna.
"Come and help!" Su Qingyun yelled at him.
Brother Jiang ran over and held the radar antenna together with her. However, the weight of the antenna, coupled with the terrible destructive force of the wind and sand, made it impossible for the two of them to hold on.
"Where are the others?" Su Qingyun asked through gritted teeth.
"At other locations." Brother Jiang answered with difficulty.
How could they not think of protecting these equipment and facilities? The security of the entire launch center was dispersed to various points, but the wind and sand were too strong and they did not have enough manpower. Brother Jiang originally planned to send Su Qingyun back safely before going to help.
Su Qingyun could only grit his teeth and persevere. In the yellow sand, they were like floating duckweed, unable to support the heavy radar antenna, which was on the verge of collapse.
A pair of hands came over to support me.
The pressure was relieved, Su Qingyun was stunned, and when she saw who was coming, she couldn't believe it.
"Captain Zhao, why are you here?"
"You little girl are here, why can't I come?" Zhao Suo pretended to be relaxed, but his hands moved with such force that veins popped out on his forehead.
"And me!" It was another familiar voice.
"I'm here too!" This was Chen Jingru's voice.
"I'm here too!"
“…”
Voices echoed in the wind and sand.
A pair of hands joined in, and then another pair, and another pair...
Knowing that there were not enough guards and worried about damage to the test equipment, researchers from the entire launch center came, formed a circle, and stubbornly supported the radar antenna. Others went to check every place to see if there was anything missed and to minimize the damage caused by the sandstorm.
The wind and sand were getting stronger, and the city was covered with dark clouds, just like the Devil City in the story, which was daunting. But everyone stood still and did not move an inch.
"Everyone, hold on, this is our hard work!"
"Don't worry, even if I fall, it won't fall!"
"Try harder, hold on!"
“…”
These words are cheering everyone up and also encouraging myself.
In the yellow sand, Su Qingyun was so moved that she burst into tears. Even though she couldn't see the people around her clearly, she knew that at this moment, they were all standing together.
