The Science Fiction World of Xueba

Time passed day by day, and before you knew it, it was time for the system to open a new plane.

At 24:00 on October 5, 2019, the system sound rang in Pang Xuelin's ear on time.

"The new plane is about to open this month, please prepare the host, ten, nine, eight, seven, six, five, four, three, two, one..."

Pang Xuelin lay on the bed and closed his eyes.

In the next second, Pang Xuelin opened his eyes again, and what appeared in front of him was a misty dark yellow. To be precise, through a transparent glass helmet, he could see the sky with countless silver iodide suspensions floating in it.

Pang Xuelin was lying on the ground, a memory was injected into his mind out of thin air.

Planes: The Martian

Identity: Pang Xuelin, mathematician, communication expert, member of the Ares III mission team. Due to the sudden global dust storm on Mars, the Joint Headquarters of the Ares Project canceled the 30-day scientific expedition, and ordered the eight members of the Ares III mission to return on a Mars Ascension Vehicle (MAV). On the way to enter the MAV from the habitat, Pang Xuelin and Mark Watney were knocked unconscious by the satellite communication antenna that fell from the base.

Background: Project Ares is a Mars landing operation led by the International Astronautical Federation and participated by many countries, aiming to establish an international Mars joint scientific research base. Ares plans to first establish a giant international space station with a mass of 50,000 tons in geosynchronous orbit. Subsequently, the International Space Station was used to build Hermes, the largest nuclear-powered spacecraft in human history. The Hermes is driven by an ion engine, and uses the electricity generated by the nuclear reactor to eject argon atoms at high speed, giving the huge Hermes a slight acceleration. After a long period of accumulation, this kind of acceleration can bring the Hermes quite a high speed. The main members of the Ares Project are China, the United States, Russia, Europe, and Japan, and the European Union joined as a whole.

Mission: Rescue Mark Wodani and return to Earth alive.

mission rewards:

1. The eyes of astronauts. (As an excellent astronaut, how can I tolerate four hundred degrees of myopia? As long as the task is completed, the host's vision in the real world will return to normal)

2. Randomly select a technology from this plane as a reward.

"Didi, warning, the oxygen concentration exceeds the standard, Didi, warning, the oxygen concentration exceeds the standard..."

On the wrist monitor, the oxygen concentration is as high as 80%.

Pang Xuelin's face was pale, his head was dizzy, and he felt sick.

Pang Xuelin knew that this was a sign of oxygen poisoning.

The bottleneck of the spacesuit life support system is not how much oxygen you bring, but how much carbon dioxide you breathe out and emit.

In the Hermes spaceship or habitat cabin, there is a large oxygenation machine that can decompose carbon dioxide into oxygen, but the spacesuit is different, it can only carry an absorption device filled with sodium peroxide, once the inside is over The sodium oxide absorbs the saturated carbon dioxide and the filter fails.

At this time, the computer that comes with the spacesuit will open the vent to discharge excess carbon dioxide, and at the same time, release nitrogen for pressure compensation.

Engineers call this emergency mode "bleeding."

If the nitrogen is released again, the system will perform the final step, supplementing the pressure with pure oxygen-this is equivalent to slow suicide.

Excessive oxygen concentration can cause damage to the lungs, nervous system and retina, causing a series of complications such as dyspnea, retinal detachment, pulmonary fibrosis, and mental disorders!

Pang Xuelin is in this state now.

"No, we must return to the habitat as soon as possible!"

Pang Xuelin barely got up from the ground, staggered and walked a few steps, and found Matt Vodani fainted aside, his abdomen was pierced by a signal receiving antenna,

Fortunately, the water in the blood evaporated in the low pressure and strong air flow, leaving a viscous residue that sealed the hole, reducing the leakage of the space suit to an acceptable level.

"This guy is so lucky, he can survive in this situation!"

Pang Xuelin squatted down to check Mark Watney's condition. Then, according to his memory, he touched a patch bag from the side of the helmet and took out the high-viscosity gum inside.

Pang Xuelin held one end of the antenna, exerted a little force, and quickly pulled it out.

"ah!"

Mark Wodani was suddenly awakened by Pang Xuelin's actions. The severe pain made him tremble all over, and even his muscles twitched.

Pang Xuelin quickly blocked the opening of the hole with gum, blocking the whirring airflow.

The air pressure in the spacesuit began to rise, and Mark Vodani opened his eyes wide, panting heavily, trying to hold back the pain.

“Wodani, how are you? Can you hear me?”

Mark Wodani looked at Pang Xuelin blankly.

"Wodani, can you hear me?"

Mark Wodani opened his mouth to say a few words, but Pang Xuelin couldn't hear anything.

"The spacesuit communicator is malfunctioning!"

Pang Xuelin immediately realized the problem.

Pang Xuelin patted Mark Wodani's helmet, and pointed to the habitat cabin more than 100 meters away. Mark Wodani seemed to be aware of the situation of the two, and made an OK gesture to Pang Xuelin.

Pang Xuelin helped Mark Wodani up from the ground, and the two staggered to the habitat cabin step by step.

Fortunately, the Habitat withstood the sandstorm without any damage.

Pang Xuelin opened the outer hatch of the airlock, helped Mark Wodani in, and opened the inner hatch again after the air pressure in the airlock stabilized.

"call……"

As soon as they entered the habitat, the two collapsed on the ground. Pang Xuelin quickly took off the helmet of the space suit, and helped Mark Wodani take off his space suit.

"Thank God, Pang, we...we're all still alive!"

Mark Wodani gasped heavily, thankfully.

Pang Xuelin said: "Wodani, are your wounds okay?"

Speaking of the wound, Mark Vodani frowned and said, "There should be something in the wound, and it hurts to breathe now!"

"Wait a minute, I'll help you deal with it!"

Pang Xuelin took off his heavy space suit, and helped Mark Vodani take off his space suit, and then cut open his T-shirt, which had been covered with scabbed blood, revealing the scarlet wound inside.

Then, Pang Xuelin found a first aid kit, under local anesthesia, took out a small screw in the wound with tweezers, rinsed and disinfected it, and sutured the wound.

In the end, Pang Xuelin put a box of antibiotics in front of Mark Vodani and said, "Here, just take it for a few weeks."

Mark Wodani looked at Pang Xuelin with a wry smile and said, "Pang, we still have a few more weeks? In this ghost place, if the oxygenator breaks down, we will suffocate to death. If the water circulation device breaks down, We'd die of thirst, if the Hab leaked we'd be blown up, and even if that didn't happen, we'd end up starving to death! Just before entering the Hab, I spotted the MAV (Mars Ascension Vehicle) Gone! They must have thought we were all dead and evacuated early!"

Pang Xuelin said: "Watney, it's not their fault. Our mission stipulates that if teammates die, their bodies must be abandoned on Mars. This will reduce the MAV's return load and increase the system's fault tolerance. , In that case, they have no choice. As for how to live in the future, it is up to man, believe me, we will definitely find a way!"

Even though he said that, Pang Xuelin was also a little anxious.

In the movie, Mark Vodani finally survived untold hardships, but this time is different. This time, there are two people on Mars, and the amount of various resources that need to be consumed is twice the original.

And in the movie, because the MAV prepared for Ares IV needs to enter the same orbit as Hermes, it has to unload a lot of equipment to reduce the empty weight.

Even so, Mark Watney nearly died in space during the space docking.

Now that there is one more person, only one person will be able to return to Earth by MAV, which means that they must be prepared to live on Mars for a long time.

Of course, there is hope.

In the memory instilled by the system, the background of this mission is somewhat different from the background in the movie.

In the movie, the Ares Project is a mission proposed by NASA. In order to cater to the Chinese market, a scene where China National Space Administration helps NASA rescue is specially added.

But in this world, the Ares project requires trillions of dollars of investment (including the geosynchronous orbit space station and the Hermes spacecraft) that no country can afford. A project that will lead.

Whether it is a super space station with a mass of 50,000 tons or a huge Hermes spacecraft, they all embody the wisdom of scientists around the world.

The Ares III mission team is composed of astronauts from eight countries: China, the United States, Britain, France, Russia, Italy, Germany, and Japan. Pang Xuelin is from China, and Mark Watney is from the United States.

Therefore, the supplies they carry are not the same as those in the movie.

In Pang Xuelin's memory, the Chinese payload of this mission contained many mealworms, fungal spores and plant seeds used to test space reproduction.

Pang Xuelin's eyes couldn't help but light up. It seemed that next, he had to give full play to his racial talent.

Mark Wodani smiled bitterly: "Pang, I don't blame them, but in this situation, the chances of us surviving are too low!"

Pang Xuelin stepped forward and patted him on the shoulder and said: "Don't think too much, we must have other ways, now let's eat something first, let's talk about it after a night of sleep!"

"Okay, bring me a packet of Kung Pao Chicken Rice!"

Pang Xuelin laughed. In order to adapt to the different tastes of astronauts from various countries in the Ares mission, each NASA has contributed its own special space meal, and Kung Pao Chicken has become Mark's favorite food.

Pang Xuelin found a pack of Kung Pao Chicken and Yangzhou Fried Rice respectively, heated them in the microwave, and made two cups of instant drinks.

The two gobbled it up.

After eating, they went back to their respective beds and fell into a deep sleep.
