The start of science and technology
Chapter 73
"Captain, we can find a place to land!" said Su Peng.
"OK." Du Xingyu finished his work and said to the crowd, "everyone, let''s take a picture before landing!"
"Mars, here we are!" in the camera, members of the Mars mission team shouted with smiling faces.
Du Xingyu recorded the video and sent it to his "trembling" short video account.
In station B, his fans are already the first in the whole station and can''t break through any more. In order to get more energy points, Du Xingyu registered the hottest trembling short video account, with an ID called "earth observation", and released his first video.
Boring fragments of time to brush short videos has become a habit of many people.
In front of the bus stop, Xiao Wang, an office worker, was brushing a short video between waiting for the bus. He brushed a bunch of videos of his little sister expressionless. Suddenly, he saw a video. His eyes glowed and excited.
"This is Du Xingyu''s chattering account? Has Du Xingyu opened chattering?"
In the short video, the content is not much, only Du Xingyu''s brief self introduction said: "Hello, I''m Du Xingyu, next to my team. After 39 days of space flight, we have reached Mars."
"We will land on Mars soon."
"Mars, here we are!" a group of players shouted at the camera.
"It''s really them! They''re going to Mars!" Xiao Wang excitedly praised and quickly left a message: "first!"
Unfortunately, more than a second after he left his message, thousands of similar comments appeared in the comment area.
"Du Xingyu entered the station, shaking? Ha ha, second attention!"
"Come on!"
"Oh, my God, look who I brushed?"
"Isn''t this account earth observation? Why are you observing Mars?"
"Are you going to land on Mars? Please update! Why is there no live broadcast on the Internet?"
The delay between Mars and earth is too high, and the signal is sometimes unstable. Du Xingyu naturally can''t live broadcast.
Du Xingyu''s trembling fans are soaring, with an increase of more than 100000 in a minute, but now he has no time to pay attention to these.
"We have adjusted our position and expect to land in three minutes!" Du Xingyu''s voice was sent to Changhai command center four minutes and 45 seconds ago, which means that when he Jingcheng and others heard the voice, they were already landing.
"Finally landing!" in the command center, he Jingcheng cheered up and stared at the screen.
In the northern hemisphere of Mars, over a lava plain, the Mars spacecraft Yinghuo is slowing down.
"The ion thruster has been closed, the extended structure of the spacecraft has shrunk, and the nuclear thermal thruster has been used to slow down. The atmospheric density here is only one percent of that of the earth, and our deceleration needs to be adjusted..." in the spacecraft, people are constantly adjusting the orientation and speed, and the spacecraft has been retracted to the shape of "rocket".
"The height is 1000 meters. The deceleration is completed. The terrain below is flat and can land."
The Yinghuo spacecraft landed slowly and landed on the ground against the reverse thrust of the tail propeller. The automatic support at the bottom automatically adjusted the height, inserted into the soil and rocks and fixed it to ensure that the spacecraft would not collapse.
"Report to the command center, the landing is completed, and we''ll prepare for landing!" Du Xingyu stood up and said to the people in the cabin: "Shen Yan and Jiao Mengyun, you stay in the cabin for the time being, responsible for liaison and command, and the rest go out with me to explore the surrounding environment."
"Yes!" everyone has put on their spacesuits and is ready to get out of the cabin.
At this time, the micro camera on the spacesuit will record these pictures and transmit them to the command center.
Countless people on earth will witness this moment together, and mankind will land on Mars for the first time!
"Open the hatch!" Du Xingyu stood in front of the connecting hatch and started the button. The hatch slowly opened, and the sun shone on his face again. The enhancement of the light made him subconsciously narrow his eyes. Outside the hatch, there was a red sand and stone Gobi!
This is the Chris plain of Mars, with low altitude, flat terrain, close to the equator of Mars, long daytime time and high solar altitude, which is suitable for the landing team to carry out tasks.
Du Xingyu stepped on the sand on the surface of Mars. The camera recorded this moment. Maybe it will be published in the history textbooks of various countries in the future.
"Insert the red flag!" Xu Lianqiu took the red flag and inserted it under the sand. It was sounded by the Martian wind!
This photo was also sent back to the earth command center. Seeing the moment when the red flag was flying, he Jingcheng and others felt tearful.
Finally, one day, the footprints and red flags of Chinese people are printed on the surface of Mars, and they are the first in the world!
Du Xingyu looked around. The landing point they chose was empty, only sand and brown rocks.
"Modular robot, geological exploration!" Du Xingyu commanded.
From the Mars spacecraft, small module robots were put down one by one. They are activated one by one, like running in all directions, and begin to use ultrasound to explore the surrounding environment.
The astronauts are carrying all kinds of materials and preparing to build a Mars base.
It''s about 9 a.m. on Mars day. A Martian day is 24 hours, 39 minutes and 35 seconds. Because the atmosphere is thin and cannot retain the heat of the sun, the temperature here is below zero degrees Celsius even in sunny days.
At night, the temperature will suddenly drop to minus 70 or 80 degrees, which is a very dangerous temperature for human beings on earth.
So before the night comes, Du Xingyu and others will return to the Mars base to rest until they have completed the construction.
At this time, the ground command center has received the video of their landing.
When Du Xingyu walked out of the landing module and Xu Lianqiu planted the red flag, everyone cheered in the command center!
"We have successfully landed on Mars! The first in the world!" shouted the members of the Mars mission team.
"In 39 days, we set a record and reached Mars in 39 days!" Zhang Yan said excitedly. "From then on, the distance between the earth and Mars will no longer be limited by the so-called orbital window period! The launch of spacecraft will not have to take the hohman transfer orbit!"
"Well done!" Liu Yuan wrinkled and laughed loudly.
"Congratulations, when you come back, all of US astronauts will celebrate for you!" he Jingcheng said to the communicator, "now, build the base as soon as possible!"
The pictures of their celebration were also captured by the camera and appeared in the real-time news.
State television: "an interim news was broadcast on the spot. At 9:08 Chris plain time in the northern hemisphere of Mars, China''s Mars mission team successfully landed on Mars. Team leader Du Xingyu and vice captain Su Peng are leading the team to carry out geological exploration... We are the first country to land on Mars in the world!"
