586: The cold, dark deep space

Professor Guo's creation is truly amazing!

Such a large spaceship.

According to the information Wang Mian received, the spaceship itself weighs over 420 tons, and its maximum takeoff weight can reach nearly seven hundred tons!

This is an extremely terrifying number!

Inside are various equipment and supplies, as well as various life support facilities.

For a behemoth weighing seven hundred tons to be able to take off and ascend into space, how incredible must the engine and propulsion system be.

Wang Mian found it somewhat hard to imagine; he was a science student, and in the past six months since being selected as an astronaut, aside from daily physical training...

...most of his other time was spent studying technology or more in-depth scientific and cultural knowledge, including the daily maintenance of spacecraft.

He had sufficient understanding of aerospace engines.

He knew very well how difficult it was.

Unbelievable! This propulsion system is actually driven by electrical energy!

This is even more incredible!

One must know that the explosive power of electrical energy can never compare to chemical energy, let alone sustained bursts.

Almost only specially formulated rocket fuel can produce enough chemical energy thrust to lift dozens of tons of weight off the Earth.

Of course, due to issues like energy efficiency ratio and thrust-to-weight ratio, for a rocket to carry dozens of tons of weight away from Earth...

...its own weight will far exceed that weight, especially the weight of the rocket fuel; hundreds of tons of rocket fuel is extremely normal.

There's no other way, this is inevitable.

Due to atmospheric gravity, and the desire to leave Earth, gravity consumes the vast majority of the fuel.

Furthermore, the rocket must reach the second cosmic velocity to leave Earth.

This process will consume the vast majority of the rocket fuel.

What finally leaves Earth is only the tip of the rocket.

The lower stages containing fuel tanks and rocket engines are discarded.

The amount of fuel that actually enters space is not much.

However, electric propulsion is completely different.

As Wang Mian understood, the Zhouguang spacecraft spacecraft he was on had two miniaturized Controlled nuclear fusion reactors.

The power generation is almost infinite.

It can reach the second cosmic velocity while flying within the atmosphere.

Then, in space, reaching a speed exceeding this speed is arguably effortless!

This is a true spacecraft!

Wang Mian felt a little emotional.

Under Earth's gravity, it can accelerate to such an extent; what speed can it reach in the zero-gravity environment of space?

The second cosmic velocity is approximately 11,200 meters per second, and this is the speed achieved under gravitational constraint.

In the universe, a speed of twenty to thirty kilometers per second is probably not difficult!

Wang Mian watched the constantly updated speed displayed on the spaceship's screen.

He was very curious about the maximum speed the spaceship was designed to reach. Although he had learned a lot over the past six months...

...he hadn't specifically studied data like the spaceship's design limit speed, and Wang Mian was currently unaware.

Before leaving the atmosphere, Wang Mian saw a speed.

12,000 meters per second!

Over forty-three thousand kilometers per hour!

At this point, the spaceship had already broken through the atmosphere.

Wang Mian felt his entire body lighten.

His gaze turned towards the window beside him.

In the vast expanse of the universe, stars dotted the sky, and against the backdrop of the huge Earth glowing brightly, he could see the land, mountains, and oceans.

"How is it? Shocking, right!"

Just as Wang Mian was staring blankly at this breathtaking scene...

...Xie Yang walked over from beside him and smiled as he spoke to Wang Mian and the other two.

At this moment, including Wang Mian, the three Deep Space Technology astronauts were all staring blankly at the scenery outside the window.

Xie Yang's voice broke their awe.

Wang Mian finally came back to his senses. He turned his head to look at Xie Yang beside him.

"Teacher Xie, it is truly shocking."

Wang Mian said sincerely.

"Haha, why call me Teacher? I just taught you a few classes; now that you've graduated, just call me Big Brother Xie!"

Xie Yang said with a smile to Wang Mian.

As veteran Moon astronauts, Xie Yang and the others were naturally qualified to teach Wang Mian and his group, and also share some of their experiences on the Moon and some precautions.

This is why Wang Mian called Xie Yang Teacher.

Since this was the trainee astronauts' first Moon landing, it was naturally led by Xie Yang and Qin Ming, the two most senior astronauts.

"Okay, Big Brother Xie."

Wang Mian quickly replied.

"This scene is indeed breathtaking!"

Xie Yang said with a slight sigh.

His gaze was fixed on the Earth outside the window, a hint of wistfulness in his eyes.

"No matter how many times I see this scene, there's an indescribable sense of awe! Even more breathtaking is seeing Earth from the Moon.

Looking at the desolate landscape of the Moon, and towards the distant Earth situated in the cold, dark expanse of the universe, that's when I truly understand how lonely we are in the universe."

Hearing Xie Yang's words, Wang Mian was thoughtful.

"Alright, everyone, get used to the zero-gravity environment of space. Use the straps to secure yourselves; the spaceship is currently flying along the route plotted by the computer.

We don't need to worry about it, but you should rest a bit. It will take about ten more hours to reach the Moon.

There will be a lot of work to do then!"

Xie Yang said with a smile to Wang Mian and the other two.

"Okay! Big Brother Xie!"

The others quickly replied to Xie Yang.

Saying this, everyone began to take out the restraint straps from their waists and tie themselves to the spaceship. This was to prevent themselves from drifting around in the zero-gravity environment.

The spaceship's cockpit was quite spacious; even with five people inside, it felt relatively roomy, and everyone could choose their preferred spot to stay.

Wang Mian chose a window seat and secured himself.

Watching the Earth gradually recede outside the window, a sudden, inexpressible sense of loss welled up in Wang Mian's heart.

His mind began to wander, and he slowly drifted into sleep.

After an unknown amount of time.

"Come on, wake up!"

A voice woke Wang Mian.

Wang Mian opened his eyes.

Xie Yang was standing in front of Wang Mian.

"Big Brother Xie, what's wrong?"

Wang Mian asked, looking at Xie Yang with a slightly confused expression.

"Look outside the window."

Xie Yang said with a smile to Wang Mian.

"Outside the window... ...we're here???"

Looking at the desolate scenery outside the window, Wang Mian stared at Xie Yang in shock.

"Yep! Put on your spacesuits, I'll take you down to have a look!!"

Xie Yang said with a smile.

Saying that...

...Wang Mian immediately unbuckled his strap, quickly put on his spacesuit according to the classroom instructions, and followed Xie Yang to the Moon.

After getting off the spaceship, what appeared before Wang Mian and the others was a busy construction site.
