Reborn in 2011, I am the chief designer of aerospace.

Soon, the simulation training ended, and the day for the official departure arrived.

Suzhou Launch Control Center.

The countdown has passed the six-minute mark.

Current time: T minus 5 minutes and 51 seconds, timer continues.

The "Search God" spacecraft stands majestically on launch pad 39A, ready for launch.

All ground checks proceeded smoothly and according to plan, and ignition and liftoff were expected in 37 minutes.

The spacecraft test commander has completed the status confirmation of all positions in the control room, all personnel have reported that they are ready, and the situation has been reported to the test director.

The test director is conducting a final review.

The mission manager has submitted the final confirmation report to the launch pad.

The Jingzhou Mission Control Center reported that all systems of the "Search God" on-orbit booster assembly were operating normally and were ready for deployment at any time. To ensure precise docking later, the spacecraft must maintain millisecond-level synchronization with the booster assembly in orbit upon launch, making today's launch window extremely short.

The launch director officially issued the clearance to launch. There are 4 minutes and 50 seconds left until launch; the countdown continues.

T -4 minutes, timer confirmed. Fuel valve heater activated, main engine enters ignition preparation state.

T minus 3 minutes and 54 seconds, timing confirmed. The final fuel line purging procedure of the main engine was initiated, and puffs of white, low-temperature steam rose and dissipated around the massive body of the Great Wall-5 rocket, slowly spreading beneath the steel launch pad.

The liquid oxygen supply system has been shut off, and the launch-stage storage tank has begun pressurization.

The ground wind speed was below ten knots, and there were only a few thin clouds at high altitudes. The launch weather was perfect, fully meeting the mission parameter requirements.

T minus 3 minutes and 40 seconds, timing continues.

T minus 3 minutes and 20 seconds, timing confirmed. "Search God" disconnected the external cable and successfully switched to internal power.

T minus 3 minutes.

T minus 3 minutes, countdown continues.

Engine universal joint oscillation testing is underway to ensure the thrust vector control system operates smoothly and is ready to take over the rocket's flight attitude at any time.

T decreases by 2 minutes and 52 seconds. The secondary liquid oxygen vent valve closes, and the fuel and oxidizer storage tanks begin pre-flight pressurization.

T minus 2 minutes and 25 seconds, timing confirmed. Liquid oxygen tank has reached rated flight pressure.

Two minutes until launch.

After crossing the T minus 2 minute mark, the timer is confirmed. Two minutes remain until liftoff.

The liquid hydrogen discharge valve has been closed, and the liquid hydrogen storage tank's flight pressurization procedure is underway.

T minus 1 minute and 50 seconds, timing confirmed. All parameters are currently normal, and no abnormalities have been found.

Commander No. 01 sent his final blessings to the astronauts over the communication channel: "Have a safe journey."

Changsheng Tianhong responded to the mission instructions: "Received, thank you very much, we are ready to embark on an exciting journey."

T minus one minute and thirty-five seconds, time confirmed.

T minus one minute and ten seconds, timing confirmed. All liquid hydrogen tanks have reached flight pressure.

T minus one minute. Mark, count.

The underwater acoustic suppression system ignition device is about to start, with only a few seconds remaining.

The launch system's thermal components have been unlocked and are ready to launch.

T minus forty-five seconds, the count continues.

T minus forty seconds, countdown begins. Flight test recorder activated, ground and "Search God" synchronized.

Astronaut Sheng Tianhong reports: "I feel good."

T minus 30 seconds.

With only seconds remaining before the redundant launch sequence is activated, this is a critical system for controlling the automatic engine shutdown.

T minus 27 seconds, timer continues.

Redundant transmission sequence has taken over control.

Twenty seconds decrement from T, countdown begins. The water spray noise reduction system in the deflector channel is activated, and the rocket engine is ready.

T minus 15, 14, and 13.

T minus ten, nine, eight.

The main engine is ignited.

……

Song Xingye, Mila, and Sheng Tianhong, all wearing orange pressure suits, were crammed into a small space, their elbows pressed tightly against each other.

They were isolated in darkness; inside the command center, only a few fluorescent lights barely illuminated their vision.

A loud bang startled Song Xingye back to his senses, and he hurriedly looked at his teammates beside him.

"The fuel pump has started," Sheng Tianhong said.

Song Xingye heard a muffled rumble, like thunder rolling from the horizon, and a chill seeped through the cushioned seat, reaching every part of his body.

Liquid oxygen and kerosene are rapidly mixing in the combustion chamber of the giant first-stage engine, undergoing a violent chemical reaction.

He could feel his heart pounding in his chest. Don't panic, damn it.

A short, stout metal astronaut doll, suspended by chains above its head, swayed slightly with the rocket, its rounded helmet silhouette seemingly grinning menacingly from the shadows. Good luck.

The noise followed one after another, exceptionally clear, the roaring sound seeming to come from the mouth of some roaring behemoth.

Song Xingye heard it very clearly, and felt his eardrums throbbing with pain. Fortunately, he had experienced this before during training, and he could barely bear it.

Sheng Tianhong shouted, "Everyone, get ready! Standby! Standby!"

Subsequently, as the thrust continued to increase, the entire rocket system entered the "stretching" phase.

Everyone truly felt the upward thrust of the spacecraft and heard the fierce roar of the Great Wall 5 under the stress of the metal.

That's how it should be. This design... is truly ingenious.

Sheng Tianhong said, "Three, two, one, ignite."

They were fully committed. These robust rockets were like giant firecrackers; once ignited, they were unstoppable until the fuel was exhausted.

The clock ticked away rapidly.

zero.

Suddenly, a slight vibration was heard, and the explosive bolt of the booster snapped.

The cabin began to shake violently, and the seat fasteners and fittings made a jarring, clicking sound.

Sheng Tianhong said calmly, "Let's go."

Mira cheered, "Go! Full speed ahead!"

Takeoff. Oh my god, we're off the ground.

A surge of excitement welled up in Song Xingye's heart, and the pressure from the acceleration made it almost impossible for him to breathe.

"Go!" he shouted. "Go!" This outburst was Yuri Gagarin's own words.

The bumps continued.

Song Xingye was violently thrown to the right, then to the left, and crashed hard into Mira.

The Great Wall 5 rocket slowly ascended, passing over the launch tower, its movements even appearing somewhat unsteady.

Its automatic control system is rapidly adjusting the angle of the first-stage engine to cope with wind shear.

It swayed from side to side and bounced back and forth, a series of violent, spasmodic shaking that almost shattered his bones.

No simulation could have predicted this extent; it was as if it had burst out from the epicenter of an explosion.

"Takeoff thrust established," Sheng Tianhong shouted. "Leave the tower."

Yang Gang, the communications liaison officer in charge of this launch, has officially connected to the communications system.

"Search God, Jingzhou received. You have left the tower."

Song Xingye lunged forward, causing the entire spaceship to tilt abruptly. He leaned back in his seat, the deafening roar slamming into his back. (Don't miss Chapter 113: Departure - Full Text Available Now! Click Here!)

The rocket is heading southeast.

The command center was only the size of a small car; it was cramped and old.

The gray and yellow walls are densely covered with dials, control switches and circuit breakers, as well as scattered fragments of notes left by staff, emergency checklists, and hundreds of neatly pasted blue Velcro squares.

The three passenger seats are nothing more than metal frames with canvas padding.

Song Xingye lay supine on the seat on the right side of the command cabin, while Commander Sheng Tianhong sat on the left and Mira was in the middle.

The main hatch is located behind Mira's head, and the inside of the hatch is equipped with a sturdy control lever, resembling the hatch of a submarine.

"Search God, Jingzhou calling, flight path is completely correct, perfectly matching expectations."

"Received, Yang Gang," Sheng Tianhong replied.

"Received, okay."

Five times the speed of sound. Less than thirty seconds into the mission, they had already reached five times the speed of sound.

There was no fear or tension in Yang Gang's voice; to him, it was just another ordinary day in the office.

The tremors grew more intense, and a rustling sound came from their helmets, like seeds shaking in a gourd.

The entire cabin was shaking violently, making it almost impossible to concentrate on observing the swaying instrument array in front of me.

"Mach 0.9," Sheng Tianhong said, "Forty seconds, Mach 1."

Suddenly, the bumps subsided, as if we were on a smooth track.

Even the roar of the engines seemed distant; they were speeding so fast that it was as if their own voices had been left behind.

"Search God, you look to be in good shape."

"The engine will rev to reduce the stacking pressure on the rocket body until the maximum Q value is reached. At that point, the combined effect of air density and booster speed will cause the rocket body to experience maximum stress. Please proceed at full speed immediately."

"Roger that, full speed ahead."

Song Xingye's chest pressure continued to increase, making it increasingly difficult for him to breathe. His lungs were struggling to resist the continuous impact.

He heard a faint thud, and the cabin shook violently, almost shaking him off his seatbelt.

The separation missile is activated, ejecting the propellant tank, which has run out of fuel, from the main thruster.

The thrust suddenly decreased, but then the core stage liquid propellant engine accelerated, and the thrust increased again, pressing him firmly back into the seat.

The booster fell like a matchstick, with smoke and flames billowing through the air.

He glanced at the G-meter; the gravitational acceleration had reached three times.

Although he was feeling somewhat unwell, he had endured even more intense shocks during centrifuge training.

Cold air blew in through the helmet, carrying a metallic smell.

Combustion in liquid fuel engines is much smoother than that in solid fuel engines.

He could clearly hear the gradually increasing roar of the engine and the continuous vibration of the equipment inside the command bay.

Everything was running smoothly and efficiently, in a regular and stable manner.

In this cramped cabin, they felt as if they were inside a giant sewing machine, and the gurgling vibrations made the sense of urgency brought about by the acceleration all the more real.

The engine was shut down as scheduled during the first phase.

The acceleration vanished instantly.

It was as if they were sitting on a catapult, and he was suddenly thrown forward, crashing into the instrument panel, his body tightly restrained by the seatbelt.

But the canvas seatbelt immediately pulled him back into his seat, and then he was pushed forward by inertia.

It's like a train collision. And, they weren't even told about this during the simulation training.

He heard the booming of the exploding bolts, which ejected the wrecked MS-IC rocket body.

Then came a series of explosions, shaking the seat he was leaning against. It was the roar of a small attitude control rocket, spraying liquid oxygen and hydrogen to stabilize the huge second-stage fuel tank.

When the second-stage engine ignited, another violent jolt struck, and he was shoved back into his seat.

A loud bang came from above, scaring him half to death, as if someone was hammering the outer shell of the command module.

Suddenly, flames shot into the sky outside the window, and thick smoke billowed out.

"Tower, report status," Sheng Tianhong reported.

"receive."

The emergency escape rocket detonated on its own, taking with it the cone-shaped escape shield above the command module.

The blinding daylight flooded into the cabin, casting dappled patterns on their orange pressure suits, making the instrument panel displays somewhat blurry.

Song Xingye looked out the window. Above him was a gradually darkening blue sky, and below him was a vast sea with churning clouds and magnificent waves.

Sheng Tianhong said calmly, "Jingzhou, we suggest that the visual design be finalized today."

Debris kept flying past the abandoned escape tower near the exposed portholes of the Search God.

These fragments, like colorful confetti, drifted off the arrow and swirled and shimmered in the sunlight.

Yang Gang said, "Shut down the engine as requested."

"Received," Sheng Tianhong replied. "Press the ECO button."

No matter what happens, the Search God must continue moving forward until the main engine completely stops and then successfully enters orbit.

"Search God, you started at 5:30. The ECO command will be executed at 8:34."

The Search God has reached fifteen times the speed of sound, its engines roaring continuously, and the spacecraft is still climbing higher. Earth's gravitational well is bottomless.

Eight minutes. "Search God, Jingzhou calling, 8:00 AM sharp, flight normal."

"It looks good," Sheng Tianhong said.

The engine's residual noise and vibration vanished abruptly, and the recoil was unusually strong.

Song Xingye was thrown forward again, then bounced back to his original position in the canvas safety belt.

"Execute ECO!" Sheng Tianhong shouted.

The engine has stopped, the second phase of the mission is complete, and the fuel has been exhausted.

This time, that heavy feeling of weight never returned. It was like the jolt of a car speeding onto the shoulder, never to return to a smooth surface.

Another muffled thud was heard, accompanied by a slight tremor.

Yang Gang said, "Received. We confirm that the Search God has completed the second-level separation."

"Uh, our value is 1.014 multiplied by 1.036."

"Received, received, 1.014 multiplied by 1.036..."

A near-perfect circular track, at an altitude of approximately 160 kilometers.

Sheng Tianhong's voice was as calm as Yang Gang's, as if it were just an ordinary day in the office.

But his "pil of documents" is currently hurtling through space at eight kilometers per second.

Song Xingye gazed out the window. The curves of the Earth's surface shimmered in the sunlight, the sea undulated like wrinkled leather, and the clouds were layered upon layered, like whipped cream, light and fluffy.

We're on track. Good heavens, he felt a tremendous sense of relief, knowing he was alive and had survived that massive energy surge.

Above their heads, the small astronaut figure was floating, with the chains that had been suspending it loosely coiled around it.
