Chapter 548: Set foot on Mars

Ground command room and Yanhuang main cabin.
The feedback sounds and the command sounds one after another, and the speed of the spacecraft decreases rapidly.
"Real-time speed Mach 38.1, ready to start the landing procedure."
"The real-time speed is Mach 30. The landing procedure is started."
"Attention departments, reconfirm the landing site."
"The landing site is determined and the landing site conditions are in line with plan expectations."
"Yanhuang began to lower its height!"
...
As the command sounded, Yanhuang, which was in Mars' orbital position, began to gradually lower its altitude.
"Real-time speed Mach 25, relative altitude 200 km, landing distance 5567 km!"
In order to allow sufficient buffer time for the spacecraft to slow down, the spacecraft did not land vertically.
Instead, draw an oblique line in the air to reduce the speed and altitude while continuously approaching the landing site.
"The real-time speed is Mach 20, the relative altitude is 187 kilometers, and the landing distance is 4,517 kilometers."
"The energy system is normal, the anti-gravity system is normal, and the speed of the spacecraft continues to decrease ..."
...
With successive sounds, Yanhuang and Zhurong kept narrowing the distance from the surface of Mars.
At the rear of the ground command room, a number of media reporters couldn't help lowering their voices at this moment, holding their breath and staring at the picture on the front holographic screen.
Countless viewers are watching the live broadcast, and at this moment can not help but raise their hearts, staring nervously at the surface of Mars approaching in the picture.
In the No. 1 villa in the rest area of ​​Huanhe Park.
Zhang's father and Zhang's mother were also watching the landing of Yanhuang.
In the living room, Zhang's mother squeezed Zhang's arm tightly with one hand and looked at the live broadcast picture on the holographic TV.
Zhang's father was pinched, but his attention was also focused on Yan Huang's landing live broadcast, and watching Huang Yan's height decrease continuously, his heart seemed to mention his throat.
"Rest assured, I asked Professor Hu of Xiacheng Space Center before. The manned ascent plan has perfect protection for Xiao Zhai's safety. It's okay. "
"Are you waiting for a landing problem, right? Besides, even if Xiao Zhai is OK, is it a good thing to have a manned landing problem?" Zhang mother said angrily.
"My fault, I made a mistake, and I shouldn't say that." Zhang's father instantly acknowledged.
...
On the ground command room, the atmosphere became more tense.
"The real-time speed is Mach 10.12, the relative altitude is 101.2km, and the landing distance is 814km."
"The life support system is operating normally and the cabin data is normal."
"The real-time speed is Mach 5.1, the relative altitude is 81.2km, and the landing distance is 112km."
As the landing procedure continued, the Yanhuang in Mars's low-Earth orbit quickly swept across the surface of Mars.
Torn canyons, bulging mountains, towering peaks, bottomless craters, and extinct volcanoes ... Various scenes on the surface of Mars are constantly captured by the external camera of the spacecraft and presented to everyone .
As Yanhuang approached the landing field continuously, the topography of Mars's surface began to gradually flatten out in the pictures captured by external camera equipment, and a vast plain appeared.
Finally, in the tense expectations of countless people, a feedback sound rang in the ground command room and inside the Yanhuang cabin.
"The real-time speed is Mach 3 and the relative altitude is 48km. The spacecraft has entered the planned landing area."
"Command the spacecraft to lower its altitude and start landing."
The command sounded, and Yan Huang, which was already above the landing site, changed course instantly and began to land vertically towards the landing site.
The relative altitude of the spacecraft began to plummet. In the picture captured by the external camera equipment, the vast confusing city has been clearly visible, and as the height of the spacecraft plummets, it seems to be approaching. Collision.
"Real-time speed Mach 1 and relative altitude 10 km."
"Yingaocheng Intelligent Control System Yingyue has taken over the control of Yanhuang, and is preparing to access the starry port of Yingwucheng."
"The real-time speed is Mach 0.5, and the relative height is 2km.
At the same time as the feedback sounded, the two external hatches at the top of Yinghuo City Star Harbor opened simultaneously.
Yanhuang and Zhurong, which have been taken over by the Intelligent Control System of Yingwucheng, have begun to fine-tune according to the position of the opening hatch of the interstellar port.
"The real-time speed is 80m / s and the relative altitude is 200m. The spacecraft is about to land."
"Attention, the spacecraft is about to land!"
at last!
Under the control of Yingwucheng Intelligent Control System, Yanhuang and Zhurong passed the outer hatch of the berth perfectly.
"Relative height 20m ... 8m"
Instantaneously, the speed and height values ​​on the holographic screen are reset to zero at the same time.
Yanhuang successfully landed!
Suddenly, the unstoppable cheers sounded inside Yanhuang and the ground command room, and the ground personnel either stood up to embrace each other to congratulate or applaud.
Behind the ground command room, a group of media reporters who could not help but hold their breath just now boiled.
"... After more than ten days, Yanhuang and Zhurong, which started from Earth, successfully landed on Mars at this moment. This is the first manned spacecraft to land on Mars in human history, and the Zhaicheng Space Center has made history again. "Pioneer of the human race!" A journalist forced his inner excitement and said quickly to the camera.
"... Here is the live broadcast of Zhai Cheng ’s manned landing on the penguin news. Just at that moment, history was born. The first human manned landing spacecraft perfectly landed on the surface of Mars. We witnessed history together!" The news reporter blushed and roared into the camera with excitement.
"... The manned ascension plan was successful at this moment. This is a historic moment. This is the first time that human beings have stepped on the surface of Mars. This will be an important step for humans to move towards the starry sky. Center, great human! "
...
With the excitement of the media, countless people watching the live broadcast couldn't help but stand up, cheer, be excited, and be proud of it.
In the starry port of Ghost Town, Yanhuang's main cabin,
Zhang Zhai listened to the boiling cheers from the ground command room through the quantum communication equipment, and looked at the excited researchers in the main cabin, with a smile on his face.
Untie the protective strap, get up from the fixed seat, pick up the communicator, Zhang Zhai said to the people in the cabin and said:
"Everyone, get out of the cabin!"
"Yes!" The crew responded with excitement.
"Close the berth door, start pressurizing, and inject air!"
The moment the sound goes down ~ EbookFREE.me ~ The top door of the berth closes to the external hatch, and the berth begins to infuse air,
"The berth is pressurized, and whether the hatch is open."
On the holographic screen of Yanhuang's main cabin, a virtual image of Yinghuo Intelligent Control System 'yinghuo' appeared.
"Open the hatch." Zhang Zhai glanced at the holographic screen.
The moment the voice fell, the doors of Yanhuang opened slowly, and the metal ladder extended down to the floor of the berth.
"Mars time 18:05, Mars surface temperature -25 ℃, Ying Huo city temperature 22 ℃, relative humidity 60, welcome to Mars-Ying Huo City." Ying Huo City intelligent control system sounded.
"Start out of the cabin!"
The words fell, and the researchers did not move, but looked at Zhang Zhai.
Feeling everyone's gaze, Zhang Zhai smiled, said nothing, and walked towards the open hatch.
Twenty researchers, just behind Zhang Zhai, started to leave the cabin.
"Hmm ..."
Through the hatch and down the metal ladder, Zhang Zhai first stepped on the surface of Mars.
