In the satellite launch base, a giant with a diameter of 3.4 meters and a height of 24.6 meters is being slowly moved upright to the launch tower not far away via a mobile platform.
A group of researchers in the control center is methodically checking the rocket one item at a time. Among them, a specialized team of up to thirteen members is repeatedly running simulations of the latest Candy algorithm.
At first, everyone called the Candy algorithm the new attitude stabilization algorithm. However, when the second version of the new attitude stabilization algorithm arrived, the name became increasingly awkward. They thought of the encapsulated algorithm as a piece of candy, and somehow someone started calling the second version the Candy algorithm.
"Elder Chen, should we postpone the satellite launch a bit, to give the testing team more time to test the Candy algorithm a few more times?"
Chen Xihe patted his old partner Zhang Xianmin's shoulder and said, "Old Zhang, don't you trust my work? Since we got the algorithm, I've organized personnel to start testing, and so far, there hasn't been any problem at all."
"Besides, there's still three days before the launch. If there are any issues with the Candy algorithm, they'll definitely show up. By then, it's not too late to delay the launch. If all else fails, we can continue using the original attitude stabilization algorithm, don't you think, Old Zhang?"
Zhang Xianmin looked at the rocket slowly being pushed toward the launch tower on the central control's large screen, feeling a bit uneasy.
In Zhang Xianmin's view, a rocket without a satellite should be used to conduct a trial, and then based on the trial data, decide if the Candy algorithm is worth promoting. At that time, deciding to use the Candy algorithm for satellite launches would not be too late either.
Although this satellite launch is merely a regular backup weather satellite, even if the launch fails and the satellite crashes, or if shortly after the launch the satellite and rocket both explode, the cost is still within an acceptable range.
The technology for various rockets is indeed very mature, but each year there are still frequent rocket launch failures caused by unexpected minor issues.
On regular equipment, minor issues might not be a big deal, or even missing some parts might not affect normal operation.
However, rockets are different; in high-speed motion, minor issues can rapidly escalate and ultimately lead to launch failure.
At the current stage, this is the same for every country.
As long as issues don't occur with manned spacecraft launches, everything else is within the acceptable range.
Satellites and other equipment can be rebuilt if lost, but astronauts cannot.
Not only does the state have to spend enormous costs to train an astronaut, more importantly, an astronaut is a living person.
Three days passed in the blink of an eye.
Inside the launch tower, all staff collaborated with the command center to conduct the final pre-launch checks on the rocket.
After three days of testing, no problems arose with the Candy algorithm, and every test result showed that under the adjustment of the Candy algorithm, the rocket's attitude was maintained with great stability.
In the control center a few kilometers away from the launch tower, Chen Xihe and several white-haired elderly sat in the last row quietly watching the young people.
This stage requires swifter reaction capabilities to respond to any potential unexpected situations.
This is one of the reasons why the majority in the control center are always the younger generation during rocket launches.
"Attention all personnel, begin evacuation from the launch tower. The satellite will ignite and launch in ten minutes."
"Repeat! Attention all personnel, begin evacuation from the launch tower. The satellite will ignite and launch in ten minutes."
Upon hearing the broadcast, all personnel on the launch tower evacuated to the buses on the ground after completing the final inspection.
As the last bus started and left, the area surrounding the launch tower was already empty.
"One minute to launch preparation."
"Three... two... one..."
"Ignition! Launch!"
On the tall launch pad, accompanied by the chief commander pressing the red launch button, all the supporting arms initially attached to the milky white giant launch rocket retracted, and all the tracking and measurement equipment at the site powered up; high-speed cameras, tape recorders, and other recording equipment all started operating.
In a moment, the rocket launch site was immediately filled with uninterrupted deafening roars.
This roar, like mountain collapses and ground cracking, like tsunamis, shook the earth.
A second later, the gigantic rocket lifted off, slowly ascending, with brilliant flames streaming from its tail, straight up to the sky.
In the control center, although Chen Xihe said nothing, his eyes, under the reading glasses, remained glued to the big screen.
To say he wasn't worried would be false!
The rocket soared upward in the blue sky. Several seconds later, the vertically ascending rocket started to turn; dozens of seconds later, the gas expelled by the rocket condensed into a cloud of smoke in the air, resembling a white ribbon stretching out into the southeastern sky, eventually becoming a bright spot that gradually disappeared into the vast horizon, breaking through the atmosphere and vanishing from sight.
Meanwhile, from our mainland to the far-reaching ocean measurement fleet, hundreds of modern measurement communication equipment designed and manufactured by our country closely "bit" onto the small bright spot invisible to the naked eye, accurately determining, recording, and reporting the rocket's flight speed, altitude, and attitude at every moment.
At every moment, a large amount of measurement data converges from all corners of the country into the measurement and control data exchange center.
The measurement and control center, through a variety of precision equipment and lines, connects all participating units into a tense combat collective, timely gathering, exchanging data and information between participating units, continuously reporting the rocket flight data to each measurement station, guiding them to accurately track the rocket.
And the measured information from each station and the rocket's flight status is promptly relayed back to the launch site's control center and command center.
Good news keeps coming!
"Tracking well!"
"Working normally!"
"Flying normally!"
When Chen Xihe saw on the big screen that the final stage of the rocket detached, his long-held tense heart finally settled.
Just like in the simulation test results, the rocket maintained a remarkably stable attitude throughout the flight process.
Moreover, when the satellite adjusted itself and entered the predetermined orbit, the attitude stabilization algorithm performed exceedingly well.
"Hahaha, let's go, Old Zhang, my treat."
All of this, however, was completely unknown to Mo Jingchun, who was currently shopping in the supermarket, as after all, the country launches so many rockets every year, and not every time there is a platform for promotion and live broadcast.
With Little Candy nestled in a baby sling, Mo Jingchun joyfully maneuvered through the large shopping center spanning three floors with a shopping cart.
"Little Candy's favorite strawberries! Grab a box!"
"No! Two boxes! I want some too!"
