Technology invades the modern world

Chapter 274 Lin Ran Lands on the Moon
Aldrin took a deep breath and looked out the porthole at the moon, which he had longed for for the past fifty-two years.

With the advancement of technology, he was able to see it through photos and videos, but humans never set foot on the moon again, and the feeling brought by photos and videos can never compare to that of the naked eye.

“Professor, I feel like I’m forty years old again. My body and soul are telling me that they are fully prepared.”

Lin Ran patted him on the shoulder: "Old buddy, get ready, we'll be going up soon."

At this time on Earth, after the Lunar Exploration Mission officially entered lunar orbit, the simplified Chinese internet was filled with nothing but joy and celebration.

Everyone is looking forward to the moon landing, and many companies are giving their employees a day off so they can go back and see it.

Even in companies that don't give employees a holiday, it's tacitly approved if you watch the live stream on your phone during the moon landing, since the boss is watching it too.

And the external network, especially Reddit.

In 2019, there was a popular post on the Space subreddit titled "Why can't we rebuild the Saturn V? Is it because we can't build the parts or tools, or have we lost some engineering knowledge?"

The accompanying image is an aerial view of the Saturn V rocket from the 1960s.

The most upvoted reply below says this:
"Well, firstly, the technology is outdated; secondly, it's too expensive—we can build better rockets for less money; and thirdly, the acceptable level of risk has dropped dramatically, while the Saturn V is fraught with risk."

There are other reasons, but why build something from decades ago when modern technology already exists and can do the job cheaper, safer, and better?

Look at starships; even the SLS is cheaper and safer.

The SLS is a heavy-lift rocket developed by NASA for the Artemis program, tasked with launching the Orion spacecraft into lunar orbit.

The project was officially launched in 2011 and received launch permission from Congress at the end of 2016. However, until the end of 2021, this super-heavy launch vehicle has not experienced a single launch.

The manufacturer of the SLS has a familiar name: Boeing.

China's Saturn V spacecraft successfully entered lunar orbit twice in a row, causing this post to resurface.

The comments below were all refutations, including the highly-rated replies within the thread, which were filled with doubts, accusations, and humiliations.

"The $1.85 million in 1969 is equivalent to $14 billion today. Even with this conversion, the Saturn V only cost half as much as the SLS. Not to mention that the SLS is facing constant delays and ever-increasing costs!"

"We have ready-made, mature solutions, yet we have to reinvent the wheel again, while those damned Chinese are already taking our solutions to the moon."

“NASA today is an organization made up of a bunch of idiots. Even if the Saturn V could be easily replicated, they would tell the public no, that the Saturn V is outdated. Why? Because they can’t get enough money out of the Saturn V or enough budget from Congress. A new heavy-lift rocket can undoubtedly achieve this goal!”

"And it's precisely because of idiots like you that NASA can fool Congress and the public, making us keep pouring money into the bottomless pit of Artemis. Do you know how much money China's lunar landing program actually cost? Less than $2 million!"

"The cost estimate of SLS is a lie, NASA's promise is also a lie, and what's even more frightening is that there will always be fools who believe such lies and even actively defend them."

The American people were very surprised by China's moon landing. They won the space race in the 20th century, and in the space race of the 21st century, China won quietly.

The Soviets were making a big fuss about the space race, actively dragging America into it, and then losing the race.

China's space program never announced that it would participate, yet it looks like it's about to win.

This naturally put the Americans on the defensive, making them feel that China was launching a sneak attack.

What broke their defenses even more was the cost. On the surface, Apollo Technology only spent 12 billion RMB. Compared with the Artemis Project, this budget was pitifully small, which was what made the Americans even more vulnerable.

It feels like the money has been swallowed up by NASA's parasites, and NASA officials are on vacation while everyone else is stuck in a tiny house.

Qian Fei and Zhao Jianguo are still resting at Tongji Wenchang Hospital, and they are also watching the live broadcast.

After successfully entering lunar orbit, Qian Fei remarked, "As expected of a professor, he is indeed very skilled."

Zhao Jianguo added, "I was wondering why our astronaut training class professors often sit quietly and listen in; it turns out he was also preparing for a lunar landing."

Qian Fei said, "I guess the professor had always planned to go by himself, but he probably intended to wait until the technology was fully mature before going. This time, he went by himself because of the circumstances."

Zhao Jianguo complained, "The Americans are really too bad; they'll stop at nothing to achieve their goals."

In a way, this is like shooting yourself in the foot; the professor going versus us going creates completely different levels of influence.

Indeed, the dramatic nature of the entire event has led to it receiving far more attention than if it had proceeded as planned.

This is true both in China and abroad.

"Yeah, the Americans are really bad." Qian Fei agreed, as the two of them were the biggest victims of the Americans' bad deeds this time.

The honor of being among the first Chinese to land on the moon was completely lost.

Frankly speaking, the fact that the two of them could remain calm and not resort to insults is already a sign of good manners.

Qian Fei continued, "When my son was on a video call with me, he asked me, 'The Americans are already so ruthless, why don't they be even more ruthless and shoot down the rocket?'"

Zhao Jianguo retorted instinctively: "Are the Americans crazy? They're just launching missiles at our homeland?"
Do they think our anti-missile system is useless, or do they think we're like we were twenty years ago, ready to bomb anything at any time?
Furthermore, from launch to separation, the Saturn V's first stage travels from an altitude of 0 to 67 kilometers and a speed of 0 to 2.7 kilometers per second in less than two and a half minutes. Could the US possibly intercept such a speed?
Even disregarding lateral maneuvering and acceleration, they probably couldn't achieve that speed alone.

Qian Fei nodded and said, "I didn't explain it to my son from a technical point of view. I just said that the Americans wouldn't dare. If they dared, they wouldn't have left the two of us lying here. They would have just blown up the Saturn V."

It's not like we're now stuck watching the professor go to the moon, only able to stare helplessly from Earth, and even have to feign a congratulatory gesture.

The gesture of blessing here refers to a reporter asking the White House press secretary during a White House press conference what they thought about China's moon landing and what they thought about Lin Ran's revelations during the interview.

The White House press secretary stated that Lin Ran's revelations were nonsense, and that the White House reserves the right to pursue legal action against those who spread defamatory statements. The press secretary also commented on China's lunar landing, saying that America had already accomplished this, and expressed pleasure at seeing another human nation venturing to the moon, wishing China success.

The White House press secretary's statement was watertight.

You say I did it, but I didn't. Are you going to do it now? I already did it. When I couldn't stop it, I offered my blessings openly.

Regardless of how well this White House performs, it has certainly done a good job of creating a good image.

However, such a statement failed to satisfy neither the Chinese nor the Americans.

How can you congratulate China on its success?

How can we continue to meet our performance targets?

The rednecks were particularly dissatisfied because they were clearly more satisfied with the former president's statements on truth-based social media.

"If I were in the White House, the Chinese would definitely not be able to go to the moon!"

Of course, if Lin Ran knew, he would definitely make you go to the deep mountains and forests of Baiyue.

任务进行到第100小时10分钟44秒，GET 100:10:44。

Lin Ran and Aldrin have entered the lunar module, wearing lightweight cabin suits, and completed system activation.

They checked the navigation, propulsion, communication, and life support systems one by one to ensure independent flight capability.

Lin Ran checked each item one by one: "Navigation computer online, RCS thrusters ready, oxygen pressure normal."

After checking the navigation computer, Lin Ran then calibrated the attitude control and confirmed the flight guidance attitude indicator, or FDAI: "Attitude calibration complete, ready for docking and release."

Inside the command module, Wei Xuhang operated the command module control panel, preparing for the separation procedure.

He confirmed via communicator: "Lunar module, command module received, system check passed, separation countdown in progress."

Lin Ran responded: "The command module and lunar module are ready to separate at any time."

The Wenchang Control Center sent a command via the Deep Space Network: "Lunar Lander, separation permitted, pay attention to attitude control."

Lin Ran confirmed: "Received, separation permission granted."

At 100:11:47, Lin Ran confirmed with Wei Xuhang, "Xuhang, we're ready. How's it going on your end?"

Wei Xuhang responded: "Everything is ready, 15-second countdown."

He initiated the separation sequence, and the screen displayed the docking lock status.

GET 100:12:03, the moment of separation has arrived.

Lin Ran pressed the "CSM/LM Sep" button, detonating the separation device. All 12 docking latches were released simultaneously, accompanied by a low "bang," and the command module separated from the lunar module.

The lunar module drifted away slowly under a weak thrust, at a speed of about 0.3 meters per second.

Separation is achieved using a docking mechanism, with 12 latches released via a rupture cord, and an RCS thruster providing a separation speed of 0.3 m/s.

The DOI uses a landing engine (DPS), propelled by liquid oxygen and liquid hydrogen, with a thrust of around 9800 pounds and a Delta-V of 23.3 meters per second. Its attitude is controlled by a navigation computer, similar to an AGC.

It's worth mentioning that this moon landing was a replica of the Apollo moon landing, so imperial units were used.

If the metric system is fully adopted, there is a high possibility that major problems could arise if even one place fails to adapt.

Therefore, to be on the safe side, imperial units will still be used throughout the entire process.

Looking through the porthole, Wei Xuhang saw the lunar module, wrapped in gold and silver foil, shimmering in the moon's reflection.

He used his camera to record the separation and confirmed: "Separation was normal, landing legs deployed, structure intact."

At the same time, it was reported via communicator: "Wenchang Control Center, separation successful, lunar lander enters free flight state."

With the moon landing imminent, Bilibili succumbed to pressure and sold the moon landing livestreaming rights to major domestic platforms including Kuaishou, Douyin, and Migu.

It was a steal; each one sold for 50 million.

This is both to divert traffic and to exert internal pressure, preventing them from monopolizing this massive influx of traffic.

You can also watch the live stream on Weibo.

However, all of these were broadcast live on Apollo Technology's official live stream channel.

At the same time, these major platforms have all issued announcements guaranteeing that all donations will be given to Apollo Technology after taxes are deducted in accordance with the law, and they will not take a share of the profits.

In the live broadcast room, the host from Apollo Technology said softly, "The Lunar Lander has successfully separated! Our astronauts have taken a crucial step towards landing on the moon."

This style has been criticized for lacking passion.

After all, many viewers love watching live streams with a shouting and yelling style.

Inside the lunar module, Aldrin had already closed his eyes to rest, preparing for the final moments to come.

Lin Ran focused intently, preparing to adjust his posture.

Lin Ran operated the RCS thrusters to stabilize the lunar lander's attitude and prevent it from rolling over.

The speed has been reset to zero, and yaw has begun.

The forest fire monitoring radar confirmed the distance to the command cabin.

The distance starts to increase steadily from 10 meters away.

Wei Xuhang then performed a yaw maneuver inside the command module, causing the command module to rotate around the lunar lander to inspect its exterior.

He reported: "The landing radar antenna is normal, and the thruster nozzles are undamaged."

Lin Ran replied: "Received, we're off!"

Wei Xuhang felt a pang of envy, but this feeling was quickly replaced by anticipation.

He knew very well that, as one of the three members of the lunar landing team, according to Lin Ran's grand plan and the abilities he had demonstrated during the year of lunar landing, he would eventually be able to personally go to the moon to carry out a mission.

At 100:13:30, Lin Ran said, "Baz, the moon is right beneath our feet!"

Aldrin replied with a smile, "Of course! Photos and videos don't have that kind of presence!"
Professor, I never imagined I'd have the honor of going to the moon with you!

After separation, the lunar lander entered independent flight mode and prepared to descend to orbit and ignite.

Wei Xuhang continued to monitor the situation from orbit, providing support for the subsequent rendezvous.

At GET 100:20:32, the Wenchang Control Center sent the DOI scheduled motion data: "TIG 101:36:14.07, Delta-V x -75.8, y 0, z +9.8 fps, orbit 57.2 x 8.5 nautical miles, attitude Roll 0°, Pitch 293°, burn time 30 seconds."

Lin Ran recorded the data and entered it into the navigation computer: "Data entered, attitude calibration in progress."

The landing engine DPS was then checked: "Engine condition is normal, fuel pressure is stable, thrust is 9800 pounds."

He confirmed the propulsion system's vector control TVC: "TVC calibration complete, ready for ignition at any time."

Wei Xuhang sent auxiliary data from the command module: "Lunar module, CSM orbit synchronization, post-DOI estimated orbit 105.9 x 15.7 km."

Lin Ran responded: "Received, thank you for your support."

At 101:35:00, the spacecraft entered the far side of the moon, and communication was lost.

The control center screen displayed "LOS," and the engineers waited anxiously, expecting to regain the signal at GET 102:16:25.

The viewers in the live stream listened to the commentator's explanation: "The lunar module has entered the far side of the moon, and communication has been lost! The DOI burn is about to take place without human monitoring. This is a tense moment in the Apollo moon landing!"

Everyone's hearts were in their throats.

"It must be completed successfully!"

"Praying.jpg"

Bilibili hastily released "Successful Moon Landing" emojis, which cost one yuan each and have filled the screen.

Inside the lunar module, Aldrin said, "Professor, you've trained countless times. Believe in yourself."

Lin Ran asked, "I've only practiced this technique for a week at most, right?"

Aldrin explained, "Professor, in my mind, your week of training is equivalent to countless times of training for others."

GET 101:36:14.07, landing engine ignites on time.

The engine spewed out scorching flames, the cabin vibrated slightly, and the thrust pressed the astronaut against the seat with an acceleration of about 0.3G.

Lin Ran stared intently at the Delta-V counter: "Delta-V 30 fps...50 fps..."

He monitored the speed changes to ensure the combustion proceeded as planned.

Meanwhile, in FDAI: "Posture stable, Roll 0°, Pitch 293°".

He silently counted down the seconds, preparing to shut off the engine at 29.8 seconds.

Inside the command module, Wei Xuhang monitored the system alone, thinking to himself, "Damn, the professor definitely isn't nervous. I feel like I'm even more nervous than the people on the lunar module!"

The combustion lasted for 29.8 seconds, after which the engine automatically shut down, the vibrations disappeared, and the astronauts regained weightlessness.

Lin Ran confirmed: "Engine off, Delta-V 76.4 fps."

Then, the data was entered, and the computer displayed the new orbit: "Perilunar point 15.7 km, apolunar point 105.9 km".

Lin Ran breathed a sigh of relief.

It has now entered low lunar orbit.

At 102:16:25, the lunar module rotated out from the far side of the moon and regained signal.

Lin Ran reported: "Wenchang Control Center, DOI successful, orbit 105.9 x 15.7 km, residual has been cleared."

Applause erupted in the control center, which responded: "Lunar module, well done! Prepare for PDI."

PDI, or powered descent process, refers to the transition from lunar orbit to low lunar orbit.

After PDI is completed, manual control is then implemented to guide the lunar lander to a landing site, ensuring that it lands on a flat area.

At 102 hours and 33 minutes into the mission, GET 102:33:00, Lin Ran was preparing for powered descent inside the lunar module. The Wenchang Control Center transmitted the PDI scheduled action data: "TIG 102:33:04, Delta-V 2917 fps, attitude Roll 0°, Pitch 55°, burn time 756.3 seconds."

Lin Ran input the data into the navigation computer and confirmed: "Data has been entered, attitude calibration in progress."

"Engine is functioning normally, fuel pressure is stable, and thrust is 10500 pounds."

"TVC calibration complete, ready for ignition."

Lin Ran then calibrated the flight guidance attitude indicator to ensure that the spacecraft was aligned with the landing trajectory with its feet down: "Attitude lock, Roll 0°, Pitch 55°."

Wei Xuhang sent auxiliary data from the command module: "Lunar module, CSM orbit synchronization, predicted landing point coordinates after PDI: 0.67409°N, 23.47298°E".

Lin Ran replied: "Received."

Wenchang Control Center confirms: "Lunar module, proceed with powered descent!"

Lin Ran took a deep breath: "Received."

The professor, who was never nervous, felt a slight tension at this moment.

In the live broadcast: "Powered descent is about to begin! The lunar landing is entering its final landing phase, and we are about to make history!"

The commentator, who had been calmly providing commentary, finally showed signs of emotional fluctuation.

At 102:33:04, the landing engine ignited, with an initial thrust of 10%, approximately 1050 pounds, lasting for 26 seconds, before increasing to full thrust, approximately 10500 pounds.

The lunar module shook, and the engines spewed out scorching flames, slowing the spacecraft down.

Lin Ran observed FDAI: "Attitude stable, thrust direction correct. Radar locked, altitude 15 km, speed 500 m/s."

During the initial descent, the spacecraft pitched at a 55° angle, feet down, and the engines continued to decelerate.

"Altitude 10 kilometers, Delta-V 1500 fps."

Through the porthole, details of the lunar surface gradually became clear.

At GET 102:40:00, the altitude dropped to about 5 kilometers. Lin Ran reported: "Radar data is stable, Delta-H 1000 feet."

Lin Ran then initiated program P64, reducing the pitch angle to 45° and tilting the porthole downwards to provide a better view.

Aldrin observed through the porthole: "The Tranquil Sea is flat, but has some small craters."

At 102:41:00, at an altitude of approximately 7.9 kilometers, the lunar module entered the high-door phase, about 5 miles from the landing site.

Lin Ran adjusted his posture to ensure that the engine thrust was aligned with the trajectory.

Then monitor Delta-H, the altitude difference between the radar and the computer: "Delta-H 500 feet, stabilizing."

In the live broadcast room, Xiao Wang shouted: "The lunar lander has entered the high-door phase, only a few kilometers from the lunar surface. The landing countdown has begun!"

Meanwhile, far away on Earth, all of Lin Ran's relatives and friends, anyone who had crossed paths with him during his childhood, were watching the live stream, their hearts pounding with anxiety.

Despite only being able to see a simulated animation on Bilibili, everyone's tension, excitement, and anticipation remained unaffected.

At GET 102:44:00, the altitude dropped to 152 meters. Lin Ran observed through the porthole and found that the automatic system was guiding them toward an area full of boulders, possibly a jet of material from a crater near Jinghai.

He immediately decided to switch control modes: "Switch to P66, I'll control it manually."

Manual operation was prepared in advance.

The spacecraft's automatic navigation system was already quite outdated. On the lunar surface, where there was no complete data collection and the ground conditions were complex, it was rare for it not to be manually operated.

Lin Ran quickly adjusted the control panel.

"P66 has been activated."

Aldrin glanced at the fuel: "Fuel 20%, approximately 120 seconds remaining."

Lin Ran gripped the control lever and calmly said, "I need to avoid that area of ​​boulders and find a flat spot."

The Wenchang Control Center communicated via communicator: "Benyue spacecraft, fuel 60 seconds."

Lin Ran nodded, focusing on the controls. He gently pushed the control lever, adjusting the lunar module's horizontal speed and direction, avoiding boulders, and searching for a flat area. Outside the porthole, the details of the lunar surface became clearer, and dust began to be blown up by the engine airflow, forming a hazy cloud.

GET 102:44:30，高度降至300英尺，奥尔德林报告：“燃料15%，90秒倒计时。”

Lin Ran was completely focused: "I can see flat ground, 200 meters ahead."

He made minor adjustments to his posture to maintain a descent rate of approximately 5 feet per second.

GET 102:45:02, Control Center reminds: "Lunar module, 60 seconds."

Lin Ran responded: "Received, target area seen."

As the altitude dropped to 100 feet, dust billowed up, obscuring part of the view, and the shadow of the lunar module was cast on the ground.

GET 102:45:32, “30 seconds!” Aldrin shouted, his voice slightly tense.

The old man has finally realized the importance of being careful.

Lin Ran remained calm: "We're almost there. Prepare to make contact."

At a height of 20 feet, 10 feet, dust swept in like a storm, blurring the portholes.

GET 102:45:40, “Contact!” Aldrin shouted.

The lunar lander's contact probe touched the lunar surface, and the indicator light lit up.

Lin Ran quickly shut down the engine, and the lunar lander landed steadily, accompanied by a slight tremor.

He took a deep breath and reported through the communicator: "Wenchang Control Center, the lunar lander has landed safely in Jinghai, coordinates 0.67409°N, 23.47298°E, fuel remaining for about 25 seconds."

Holy crap! Professor is awesome!

"President Lin is awesome!"

"We did it!"

The Wenchang control center erupted in enthusiastic applause, and the engineers cheered and embraced.

This is where the difference becomes apparent: engineers at Apollo Technologies generally address each other as "professor."

This is because the original backbone of Apollo Technology, namely those old NASA staff, were used to calling Professor Lin Ran, and this habit formed.

Even those who initially called him "General Manager Lin" gradually changed to "Professor."

The engineers at China Aerospace called him General Manager Lin.

The commander in charge of communications responded: "Lunar module, well done! Welcome to the moon!"

Lin Ran's father was filled with mixed emotions. He didn't actually support Lin Ran applying for aerospace engineering. In his opinion, aerospace engineering couldn't compare to computer science. If he wanted to work in the industry, he should study computer science; if he wanted to go into academia, he should study statistics, which was his field.

Why study aerospace? Graduates can only work for state-owned enterprises. Once you're in a state-owned enterprise, forget about income. As for a sense of honor, it all depends on luck.

Unexpectedly, it turns out that the strong create the environment.

My son is truly a genius. Look at the environment he created! He created Apollo technology and sent me straight to the moon.

Lin Ran's mother, however, didn't have so many thoughts; she was only worried about whether her son could return safely.

Besides being happy for Lin Ran, Li Xiaoman thought that Lin Ran hadn't lied to her when he asked her for the Fabian Society badge back then; it really was to replicate Project Apollo. She then lamented that Bezos and Blue Origin were blind to his worth.

They let the real gold slip through their fingers, even though it was right in front of them.

"A historic moment! Apollo Technologies astronauts have successfully landed on the moon! The lunar module made a perfect landing in the Sea of ​​Tranquility, marking a new chapter in China's space exploration!"

We have faced countless doubts, such as whether the moon landing in a year and a half was just a boast or a lie fabricated to attract investment. We have explained countless times, but now there is no need to explain anymore. The facts are right in front of us: we did it!

Under the guidance of China's space program, we are the world's first organization to land on the moon, and we will soon once again leave human footprints on the moon!

I also want to say that Shanghai Jiao Tong University, which was deeply involved in the Apollo moon landing project, is truly the No. 1 university in Shanghai!

The comments were all filled with "6" and "tears in my eyes".

At this moment, the Tongji University student group is filled with excitement:
"No, we all went to the factory one by one to tighten screws, assemble, learn welding on the spot, help debug 3D printing equipment, and participate in engine manufacturing. Now, only Jiaotong University is deeply involved?"

"Yeah, @木子成舟, Director Li, no, you have to report this to the school! The school has to lodge a strong protest with Apollo Technology! What do you mean by Jiaotong University's deep involvement? We alumni who were just fixing screws aren't considered deeply involved, are we?!"

"We won't compete for No. 1 in Shenhai. It's fine for us to compete with Fudan for No. 2, but we can't let Jiaotong University monopolize this deep involvement."

Tongji alumni, especially those who had interned there and knew about the internship program, all spoke up in WeChat groups, saying that the host of the live stream was not qualified enough, how could they not mention Tongji's contributions at all!
At this moment, in the president's office of Jiaotong University, Chen Jie, Jin Li, and Lin Zhongqing are watching the live broadcast together.

At the moment of success, Jinli said weakly, "Old Lin, I think it's actually quite good to be able to screw in screws. We at Fudan University can do that too."

Lin Zhongqing smiled without saying a word, while Chen Jie was quite pleased with himself, thinking to himself, "See? We have to seize every opportunity to tighten screws."

After landing, Lin Ran and Aldrin exchanged a smile and breathed a sigh of relief.

Lin Ran said, "We did it, Baz."

Aldrin responded, "Yes, Professor, this is a great moment."

Through the porthole, they saw the grayish-white soil on the lunar surface, the distant craters, and the tranquil plains—everything appeared mysterious and magnificent.

Lin Ran reported to Wei Xuhang via communicator: "Xuhang, we've landed safely. How are things on your end?"

Wei Xuhang replied from inside the command module: "Everything is normal, command module, well done! I'll be waiting for you in orbit."

He was very envious.

Lin Ran then checked the system status: "Pressure is normal, power is stable, and there are no leaks."

"The ground is flat, which is suitable for EVA."

They began the post-landing procedures to prepare for extravehicular activities.

At the 104th hour of the mission, GET 104:00:00, Lin Ran and Aldrin began EVA preparations inside the landing module.

At least 500 million people around the world are waiting for the live broadcast of Lin Ran's exit from the spacecraft.

From Asia to Europe to the Americas, Chinese people all over the world are eagerly awaiting this moment.

Besides Chinese people, many foreigners were also waiting for the live stream.

This is a moment that belongs to all of humanity.

The spread of the virus has also contributed to the increase in viewership.

They donned spacesuits designed with reference to the Apollo A7L, made of white multi-layered material with red stripes, and embroidered with the Chinese national flag and mission badges on the chest.

The spacesuit is equipped with a portable life support system that provides oxygen, cooling, and communication capabilities. It weighs about 85 kilograms, but feels lighter under one-sixth of lunar gravity.

Lin Ran helped Aldrin connect the PLSS backpack and checked the sealing ring: "Oxygen interface locked, seal normal."

Looking at Aldrin wearing a spacesuit with the Chinese flag, and recalling the 60th era, Lin Ran stood in the locker room, where Aldrin was wearing a spacesuit with the American flag, hoping to hug him before starting his mission.

Lin Ran was filled with mixed emotions at this moment.

After putting on their spacesuits, they tested each of the PLSS functions.

Lin Ran tested the communication through the headset: "Wenchang Control Center, lunar module EVA ready, communication test, please respond if you hear me."

The Wenchang Control Center responded: "Lunar module, signal is clear, preparing for EVA."

Lin Ran checked the cooling system: "Water circulation is normal, temperature is 22 degrees Celsius."

Then confirm the oxygen supply: "Oxygen pressure 5 psi, expected to support for 3 hours."

Wei Xuhang sent support data from the command module: "Lunar module, CSM system normal, relay communication at any time."

Lin Ran replied: "Received."

At GET 108:50:00, Lin Ran opened the pressure relief valve, and the air in the cabin was slowly discharged through the exhaust port, and the pressure dropped from 5 psi to 0, a process that lasted about 5 minutes.

The instrument panel showed that the pressure was zero. Lin Ran said, "The pressure inside the cabin is zero. Prepare to open the cabin."

Both of them took a deep breath: "Alright, Buzz, the historic moment has arrived."

Lin Ran gave up his seat and let Aldrin go first.

Aldrin stopped moving: "Professor, you can go out now."

Lin Ran asked in confusion, "Baz?"

Aldrin said, "Professor, if it were me fifty years ago, I would have stepped out without hesitation."

But Buzz, who was over ninety years old, realized that fame and fortune were not important; what mattered was going to the moon.

Professor, thank you. During this process, I have repeatedly reflected on my life and searched for its true meaning.

I am happier than many people because I was able to find meaning in life at the end of my days.

Professor, please go first.

"Both times I was the second to exit the capsule; history will remember me for that too." Seeing that Lin Ran didn't react, Aldrin added.

In the live stream: "The lunar module is about to begin EVA! Burning God and Buzz are inside the decompression chamber, preparing to open the hatch. Don't miss it!"

At 108:55:00, Lin Ran pulled the rope, activating the modular equipment storage components on the lunar lander's descent stage.

A high-resolution television camera automatically deployed, aimed at the cabin door, ready to record this historic moment.

The camera transmitted images back to Earth via wireless signals, with a clarity far exceeding that of the black-and-white images from Apollo 11.

Lin Ran confirmed: "The cameras at the Wenchang control center have been deployed, and the video transmission is normal."

The control center responded: "Received, the picture is clear, the whole world is watching right now."

Lin Ran carefully opened the hatch, and the magnificent scenery of the lunar surface came into view: grayish-white soil, distant craters, and a deep black sky.

He climbed out of the hatch, stood on the front platform of the lunar module, looked around, then grabbed the ladder and slowly descended, taking each step with great care.

At the bottom of the ladder, he paused for a moment, gazing at the lunar surface, then gently stepped down, his footprints embedding deeply into the fine soil.

He said through the communicator: "This is a small step for me personally, but it will not be a giant leap for Apollo technology, much less a giant leap for mankind."

When everyone has the opportunity to leave their footprints on the moon, that will be a giant leap for mankind.

Apollo technology will achieve this, transforming the moon into a forward outpost for humanity's journey into space.

Unlike the past, when humans failed to set foot on lunar soil for 52 years after the Apollo moon landing.

We will imbue the moon with a more realistic meaning, rather than just a cold, impersonal space symbol!
