(Extra for Alliance Leader Feitian General Alliance, Brother Chen!!) Chapter 491: Chapter 80 Jask!
(Extra for Alliance Leader Feitian General Alliance, Brother Chen!!) Boom!!!!!!!!
A roaring boom erupted!
The entire cabin shook violently.
But what followed was the intense acceleration overload that pinned everyone to their seats!
Pinned down firmly!
It was as if an invisible force was pressing down on every inch of their skin, squeezing!
Pummeling!
The force not only lingered but grew more intense and persistent!
Their organs were twisted together!
This was the great overload caused by the rocket’s acceleration upon takeoff.
Luckily, the seatbacks were soft enough, and combined with the extensive adaptation training the group had already received at the Astronaut Training Base, this sudden overload impact merely caused an unexpected jolt of tension among them, without inducing any actual unbearable sensations.
“Altitude increasing…

2000 meters…
5000 meters…”
“Yaw nozzle ready, initiating attitude adjustment, 3, 2, 1, activate!”
Over the radio channel, the broadcast from the ground control center continued.
Twenty seconds after the rocket’s ascent, the passengers inside the Skyspace Aircraft could distinctly feel the rocket’s body starting to tilt, and their bodies involuntarily began to brace.
“Don’t be nervous, this is the rocket adjusting its course.”
Wei Cheng reassured everyone over the radio channel:
“The rocket doesn’t travel vertically into space as one might intuitively imagine.
After ascending to a certain height in vertical launch, the first-stage propulsion’s yaw nozzle will adjust the rocket’s posture, tilting it, so it can gradually enter Earth’s orbit.”
“So, our posture is going to tilt a bit soon, just relax, it’s the same as our usual training.
Moreover, the current overload value isn’t that great.
The real test will come when the second-stage propulsion starts.”
“Also, a reminder to everyone, pay more attention to the penguin toy hanging in the cabin; it’s a gravity indicator.
It will enable your brains to clearly understand the direction of gravity and avoid dizziness.
So, don’t look around, just focus on the little penguin to figure out where the ground is and where the sky is.”
…
In fact, Wei Cheng had already lectured on this knowledge many times on the ground.
But that was on the ground.
Now, being inside the rapidly ascending rocket, with the pitch-black fairing outside and no visible reference point, it was natural to feel a bit of panic.
Lin Xian, Gao Yang, Chu Anqing, and Liu Feng, following Wei Cheng’s words, began to watch the small penguin toy hanging by a thread from the cabin’s ceiling.
When everyone first boarded the rocket, the little penguin hung motionless, perfectly vertical.
But now, the little penguin was leaning to the side, as if blown by the wind, or as if an invisible hand were nudging it to lean left.
But in fact, it wasn’t the penguin that was tilted.
It was Lin Xian and the others.
The direction the little penguin leaned toward indicated the vertical direction of Earth’s gravity — it was the upright one.
Watching the little penguin.
The sensation of dizziness in the crew vanished instantly.
That was the benefit of a reference point: the brain’s judging of gravity direction instantly gained a benchmark.
After another long minute had passed,
The voice from the ground control center came through the radio channel:
“Altitude has exceeded 100 kilometers, entering the thin atmosphere, jettison the escape tower!”
Immediately.
Lin Xian felt a jolt.
It was the escape tower at the very top of the rocket detaching.
The purpose of the escape tower is to launch immediately with the cabin below it, flying out in case of rocket failure within the atmospheric boundary, separating from the rocket.
Then, after reaching a sufficient height and distance, it would deploy parachutes to allow the cabin to drift slowly back down to Earth.
In essence, the escape tower was a miniature rocket.
In the less advanced era of space technology, escape towers saved many astronauts’ lives.
But now, the rocket that Lin Xian and the others were on had crossed the 100-kilometer atmospheric Kármán Line and entered space.
The escape tower had outlived its purpose.
Moreover, only by discarding the escape tower could they proceed with opening the fairing and deploy the Skyspace Aircraft later.
“First-stage propulsion fuel depleted!
Prepare for separation!
Second-stage propulsion ready!”
“First-stage propulsion completely detached!
Second-stage propulsion starting!”
Another shake coursed through the cabin.
Wei Cheng had explained to them that the rocket’s propulsion was divided into three stages.
The main process of the first stage was to push the rocket out of the atmosphere with four fuel-laden first-stage propellers combined with liquid oxygen.
After that, these fuel-depleted propellers would fall away, triggering the second-stage propellers to continue propelling the rocket into higher altitudes.
Suddenly!
Another wave of intense acceleration overload!
The crew members’ bodies were firmly pressed into their seats!
Lin Xian felt as though he was nearly flattened, almost fused with the seat behind him!
The entire radio channel fell silent.
Even the previously cheerful Wei Cheng could not manage to speak under the heavy 4g acceleration overload.
Lin Xian felt his lungs were almost crushed, truly struggling to breathe.
At that moment, the voice from the ground control center came again:
“Entering predetermined space altitude!
𝑛𝗈𝘃𝕘𝘰.co
Thermal fairing detaching!”
Click.
A slight vibration.
Lin Xian and Chu An watched through the windows of the Skyspace Aircraft as the fairing that had enveloped it while breaking through the atmosphere split open!
At this altitude, which was close to a vacuum, there was no air friction to generate heat.
Therefore.
Naturally.
The thermal fairings had completed their mission of protecting the Skyspace Aircraft on its journey out of the atmosphere and had become redundant.
