Manned spaceflight is a round-trip flight activity for humans to drive and ride on manned spacecraft in space to engage in various detection, 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, and expand the scope of human activities. Expand from the earth to space, fully understand the entire universe, and develop rich space resources.
This is a highly difficult systematic project that integrates the country's political, military, economic, and scientific and technological strengths. To complete this huge project, three major technical problems must be overcome.
The first is that high-thrust launch vehicle technology is required to send very heavy spacecraft to low-Earth orbit. The second is the safe return technology of satellites. The third is good environmental control and life support technology systems. These three points Every point is crucial and indispensable.
Everything is difficult at the beginning, and 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 even wanted to run when he walked. He was thinking even when he was eating and sleeping. The entire launch center The status of the researchers is almost the same, but while they are busy, everyone also feels full and satisfied, because everyone is in the same heart, has the same goals and ideals, and even walks with the wind.
In such busyness, the book of time turned another page and arrived in 1981.
Su Qingyun dragged her tired body out of the laboratory. She was extremely tired. The strong wind blew by, making her shiver with cold, and she quickly woke up.
She raised her eyes and looked at the sky in front of her, and was stunned. The dark sky was faintly glowing with red light, and the visibility was extremely low. It was also accompanied by wind and sand, blowing into her mouth and nose. Su Qingyun was instantly choked and coughed, and her eyes were blurred. I couldn't open my eyes and could only lower my head to protect my mouth and nose.
"Researcher Su, why are you still here?" A voice came from the darkness, surprised and anxious, "There is going to be a sandstorm soon. Go back quickly, stay in the house, and don't come out!"
Su Qingyun couldn't see the face of the person coming, but he could tell from the voice that it was Brother Jiang who was in charge of security at the launch center. He turned on the flashlight in his hand. After Su Qingyun rubbed her eyes and shed emergency tears, she was finally able to see. Something is clearer.
"I just came out of the laboratory." Su Qingyun said with difficulty, "Why is there a sandstorm? What level is it?"
Having stayed at the launch center for almost two years, Su Qingyun has not experienced sandstorms. This is a desert area. Sandstorms are not a rare phenomenon, but large-scale sandstorms that look as menacing as today have never really happened.
"The weather monitoring center said it was probably a sandstorm with wind speed of level 9."
"What?!" Su Qingyun's expression changed, and her heart tightened.
A sandstorm with a wind speed of level 9 is already a strong sandstorm. It is very harmful to life and production, not to mention their crucial launch center. Sandstorm weather will bring very serious consequences and can destroy many things. Very destructive.
Su Qingyun only felt that the wind in front of her was getting stronger and stronger, with a crushing posture, and she could hardly stand still. Brother Jiang quickly supported her.
"Researcher Su, let's go and get indoors quickly, otherwise we won't be able to leave when the sandstorm comes later."
"Where are the rest of them?" Su Qingyun asked.
"The other researchers are safe. Zhao didn't see you and asked me to come find you." Brother Jiang explained.
"That's good." Su Qingyun breathed a sigh of relief, and then suddenly thought of something, her expression changed greatly, "What about those test facilities and equipment?"
"What?" Brother Jiang didn't understand.
Su Qingyun didn't have time to elaborate, so he ran away. He was extremely anxious. Many of the test facilities and equipment in the launch center were placed in the open air at various points. The launch towers, experimental workshops, radar antennas and other equipment and facilities would be vulnerable once a sandstorm came. , it is very dangerous, and their previous hard work will be ruined.
She was running in the wind and sand, unable to see the direction clearly. She could only rely on the route in her memory to follow the surrounding directions. The anxiety in her heart made her unable to care about anything else.
"Researcher Su, don't run away, it's dangerous!" Brother Jiang was also anxious and quickly chased after him with a flashlight.
When Su Qingyun came to the launch center, the wind and sand were getting louder and louder, and the whistling sound was like a ghost crying and a wolf howling, which made people panic. However, she couldn't care about anything. All she could see was the radar antenna that was about to collapse. She used Run over as fast as you can.
"Researcher Su, danger!" Brother Jiang was almost frightened when he saw her running over to hold the radar antenna.
"Come and help!" Su Qingyun shouted at him.
Brother Jiang ran over and held the radar antenna with her. However, the weight of the antenna and the terrible power of the wind and sand destroyed it, and the two of them could not support it at all.
"Where are the others?" Su Qingyun forced out the question through her teeth.
"At other points." 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. However, the wind and sand were too strong and they did not have enough manpower. Brother Jiang was originally planning to send Su Qingyun back safely and went to help. .
Su Qingyun could only grit his teeth and persist. They were like swaying duckweeds in the yellow sand in the sky, unable to support the heavy radar antenna at all, and they were about to collapse.
A pair of hands came over.
The pressure was relieved, and Su Qingyun was stunned. When she saw clearly who was coming, she couldn't believe it.
"Zhao Suo, why are you here?"
"You little girl are here, why can't I come?" Zhao Suo pretended to be relaxed, but his hand movements were so hard that veins popped up on his forehead.
"And me!" It was another familiar voice to her.
"I'm coming too!" This was Chen Jingru's voice.
"I am also here!"
"..."
One voice after another resounded in the wind and sand.
A pair of hands joined in, and then another pair, and another pair...
Knowing that there were not enough security guards and worried about damage to the test equipment, researchers from the entire launch center came, formed a circle, and tenaciously held up the radar antenna. Others went to check various places to see if there were any missing items. place to minimize the harm caused by sandstorms.
The wind and sand became stronger, and the black clouds pressed down on the city, just like the devil city in the story. It was daunting, but everyone remained motionless and did not move a step.
"Everyone, hold on, this is our hard work!"
"Don't worry, it won't even fall if I fall!"
"Try harder and hold on!"
"..."
These words are cheering for everyone and encouraging myself.
In the sky full of yellow sand, Su Qingyun was moved to tears. Even though she couldn't see the people around her clearly, she knew that at this moment, they were all standing together.
