Chapter 401 Red Ribbon

"Zhurong's Lin Zihan calculated a navigation plan that will allow the Zhurong to return to Mars. According to his design, the Zhurong can fly past Mars before the 549th Earth Day."

There was a moment of dead silence.

"Are you kidding me?"

"549? How is this possible? If the supply ship does not explode, it will not land until the 588th day."

"The supply spacecraft is a point-propulsion aircraft. The power source of the Zhurong is a Hall propulsion engine that can continue to advance. It is constantly accelerating. In addition, the current speed of the Zhurong is very high. During their current journey into Earth's orbit, the next

The moon must slow down to match the speed of the Earth."

"...549, this is 35 Earth days earlier than he will run out of food. All problems have been solved."

Lei Jiayin's potato farm was destroyed, and the food that could have lasted for more than 800 days could only last for nearly 600 days no matter how frugal it was.

The hastily manufactured supply spacecraft that sacrificed countless functions also failed to launch.

Even if we don’t consider how long Lei Jiayin can persist, even if it takes 50 days to build a supply aircraft again, there will be no second Long March 9, and there will be no second Long March 9 propeller.

According to the rover's solar charging efficiency, power, range and speed, as well as the need for major modifications to the launch rocket after arriving at the destination, it is necessary to set off at least a hundred Earth days in advance when the Zhurong passes by Mars.

It took 50 days to cross 3,200 kilometers to reach the destination, and then another 40 days to modify the rocket.

Lei Jiayin used a knife to cut a hole in the palm of his left hand. Air jets shot out and collided everywhere in the narrow spacecraft, but he still seized the opportunity and flew out of the hole.

Every time a manned fire detection is carried out, an aircraft must be used to place the lift-off vehicle rocket to help the astronauts evacuate to Mars in advance, and some materials will also be dropped on Mars in advance.

Five lives, and a spaceship worth hundreds of billions.

The Zhurong will not enter the earth's orbit, but will get close to the earth to use the earth's gravity to adjust its course. During this period, they will dock with the supply spacecraft launched from the earth to obtain the supplies needed to extend the voyage.

After the initial excitement and exclamation, the audience was mesmerized to enjoy the unique audio-visual spectacle of "The Martian".

When he opened his eyes again, his chest hurt and he gritted his teeth.

Of course it’s impossible!

Amidst the ethereal music and the tight breathing of the audience, Lei Jiayin, who passed by Wu Yue, reached out and grabbed the red ribbon flying in space.

Male protagonist: "Habitat capsule canvas? Is this used for orbital launches!?"

Human value, human nobility, and people's belief in the country and human society are priceless and cannot be summarized by the paradox of the trolley problem.

The two people holding each other, separated by a mask that reflected stars, sunlight and Mars, glass touched glass, joyful smiles reflected in each other's eyes, and fluttering red ribbons surrounded them.

Male protagonist: "So, you mean, I'm going to launch in a spaceship with a big hole in the bow?"

"Exploring Mars and landing on the moon are not at the same level of difficulty. The journey is measured in years. Anything can happen during such a long space journey, so all possible plans will be designed..."

The audience in the theater was stunned. This dialogue without any visual spectacle shocked the audience more than most visual spectacles.

The significance of the rescue plan itself has surpassed that of the Apollo program, surpassed the Yinghuo program in the movie, and surpassed all ambitious space programs in human history.

However, it was too fast to enter orbit and could only fly past Mars. The remaining route will bring all astronauts back to Earth 211 days after passing Mars.

The rover's left front wheel sank in, and the sudden tilt caused the right rear wheel to completely lift off the ground and slide into the dust.

But this meeting, which confused the audience in the theater, caused another uproar.

"Oh my god..."

Wu Heng stared at the big screen with his eyes wide open amid the exclamations in the theater. Impossible, could Chen Jingxing really have a be ending?

Pressing his left hand backward, Lei Jiayin shook his bulky spacesuit with the jet of air, crossed the quiet night sky, stepped on the red planet under his feet, and flew towards Wu Yue.

In the boundless space, against the background of the red planet, a long red rope fluttering like a ribbon connects Lei Jiayin and Wu Yue, spinning and approaching, as if they are dancing a space waltz.

After that, Zhurong will fly to Mars along an accelerated orbit and arrive on the 549th Earth Day after the protagonist lost Mars.

But the relative speed exceeding 6 meters made the two hands unable to separate.

Fortunately, the pressure chamber was intact and Lei Jiayin escaped death again.

It seems that many other viewers also thought of the same scene as Wu Heng.

Wu Heng once again seemed to see the astronaut played by Lei Jiayin in "Gravity" find the heroine played by Wu Yue floating in space. The two held each other tightly, in the dim night sky and vaguely on the ground. They hugged each other joyfully while whirling around in the visible city lights.

In addition, the rover also needs to carry all the food, water, solar panels, additional batteries, tools, and spare parts needed by Lei Jiayin.

Some things are not just for the parties involved, or only for the dead, some things are meant to be seen by the people who are still alive.

As the rocket continued to rise, the atmosphere became thinner, and soon the canvas stopped billowing and the sky turned from red to black.

This poem appeared again. After the commander played by Wu Yue finished his explanation, he read the autobiography written by the once legendary aerospace hero.

If it is he in the end, there is no more happy ending than this.

Of course, there is also Tianwen-1. As the only communication channel, Tianwen-1 has to ride on the roof of the rover.

Later, under the command of the Earth Control Center, in order to minimize the load and approach the orbital altitude of Zhurong's pass over Mars, the rocket underwent major modifications that stunned the audience.

One of the two rovers is used for driving and the other is used as a cargo trailer.

Even if destruction is right in front of you, you still have to give it a last try.

There is another unique beauty compared to the earth.

But there is still a constant distance from Lei Jiayin.

Lei Jiayin wore a space suit and climbed to the top of the impact crater ring to find a way out. Of course, the audience once again enjoyed a visual spectacle.

The wind speed was not fast, but the sandstorm blocked 80% of the sunlight, which not only affected the efficiency of the solar panels but also caused the male protagonist to accidentally drive onto the steep slope of the Mars crater.

Wu Yue struggled to grab the red rope and tried his best to recover it, while Lei Jiayin held on to the rope tightly. Under the force and speed of the two astronauts at both ends, the red ribbon began to rotate and fold, constantly pulling the two people.

close.

In addition, three of the five batteries were discarded, as were the auxiliary power systems. The orbital maneuvering system had three redundant thrusters, and the second and third communication systems were also discarded.

"ah!!"

"Of course it's worth it." Wu Heng, who didn't know much about aerospace knowledge, heard his companion's unconscious question and replied softly and resolutely: "On the battlefield, the army should try its best to drag the bodies of those who died in the battle back to the trenches, even if

Why risk death and bring back the bones after decades?

This is for living people to see."

"Don't go gentle into that good night... rage, rage against the dying of the light!"

The rover had rolled over to one side, and at the same time, all the solar panels stacked on the roof slid down and spread to the ground like a stack of playing cards.

"Is it worth it?"

The surprise for him was even better than the hero digging up the Tianwen-1 from twenty years ago and establishing contact with the earth.

"Don't!"

Throw away all life support equipment. Tanks, air pumps, heating, air ducts, carbon dioxide absorption systems, and even the insulation materials inside the hull. Lei Jiayin has to wear an extravehicular space suit throughout the entire flight.

He drove the rover into a sandstorm area.

Before that, on the Earth side, the Zhurong was about to go around the Earth at high speed, and the Long March 5 was preparing to launch supplies. The execution was theoretically feasible, but the docking had never been done at such a high speed in human history.

Under the light of stars that traveled 200 million kilometers, Lei Jiayin wore a space suit, exposed his upper body on the upper half of the rocket, and rotated upside down as the cabin rotated.

"It's too exaggerated..."

Earth: "The hull is originally for sealing. The Martian atmosphere is extremely thin and does not require much streamlined design. By the time the spacecraft reaches a speed where air resistance needs to be considered, it has already risen to a place where there is little air. We have already run away

After many simulation tests, there should be no problem."

He already understood what Chen Jingxing wanted to express over and over again.

The ground will also use the excuse of a malfunction of the spacecraft to disconnect the signal until the spacecraft adjusts to the return orbit.

The rolling Lei Jiayin and Wu Yue were getting closer and closer.

There was not much canvas covering the top of the rocket left, and only some rags were still floating around the edge of the big hole, which gave him and the audience in front of the screen an unobstructed view of Mars.

Therefore, the lift-off rocket must lose weight, and the male leader carried out major modifications to the rocket under the guidance of the space agency.

Wu Yue selected the female astronaut who is the petite among the five and needs the least food. If the material docking fails, she will be the only astronaut who can survive.

Directly in front of him, as the spacecraft accelerated at a geometric level, the bow patch on the canvas of the habitat cabin was also vibrating crazily.

"There are four minutes left." Wu Yue said into the microphone: "How do you feel down there?"

Also need to remove a first stage engine

What was even more eye-opening for all the viewers was that the entire bow of the rocket was also removed directly.

And most importantly, when the Zhurong passes the Earth at high speed, the Earth will launch a carrier rocket to deliver supplies, and high-speed docking is a big challenge.

The modified rover must carry the "three major pieces", an atmospheric regulator, an oxygenator, and a water circulation device. These three major pieces can only work under normal air pressure, but the space inside the rover is obviously not enough.

Moreover, these three major pieces require non-stop work.

A hymn to human exploration of the universe.

After finally driving out of the impact crater and sandstorm area, the rover drove over an inconspicuous ridge while going downhill on a seemingly ordinary slope.

Through calculation, if the maneuverable airlock cabin leaks and the bridge and reactor room are sealed, the Zhurong can be accelerated to 29 meters per second, and the relative speed will drop to 13 meters per second.
To be continued...
