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

At 24:00 on the evening of October 5, 2019, the system sound sounded in Pang Xuelin's ears on time.

"A 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's eyes opened again, and what appeared in front of him was a foggy dark yellow, to be exact, through a layer of transparent glass helmet, he could see the sky that seemed to be floating with countless silver iodide suspensions.

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

Plane: The Martian

Identity: Pang Xuelin, mathematician, communications expert, member of the Ares 3 task force. Due to the sudden global dust storm on Mars, the Ares Joint Command canceled the 30-day expedition and ordered eight members of the Ares 3 mission to return on a Mars liftoff vehicle (MAV). On the way from the perch to the MAV, Pang Xuelin and Mark Watney were knocked unconscious by a satellite communication antenna that had detached from the pedestal, and the spacesuit's biochemical monitoring system failed, causing teammates to believe they were dead.

Background: The Ares program is a multinational Mars landing operation led by the International Astronautical Federation (IAF) to establish an international Mars joint research base. The Ares program will first build a 50,000-ton international space station in geosynchronous orbit. Subsequently, the International Space Station was used to build Hermes, the largest nuclear-powered spacecraft ever built by mankind. Powered by an ion engine, Hermes uses electricity generated by a nuclear reactor to eject argon atoms at high speed, giving the massive Hermes a tiny acceleration. This acceleration, accumulated over a long period of time, can give the Hermes a fairly high speed. The main members of the Ares plan are China, the United States, Russia, Europe, and Japan, and the European Union has joined as a whole.

Mission: Rescue Mark Vodani and return to Earth alive.

Rewards:

1. The eyes of an astronaut. (As a good astronaut, how can you allow 400 degrees of myopia?) As long as the task is completed, the host's real-world vision will return to normal)

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

"Didi, warning, oxygen concentration exceeded, drip, warning, oxygen concentration exceeded......"

On the wrist display, the oxygen concentration is as high as 80 percent.

Pang Xuelin's face was pale, his head was groggy, and he felt nauseous.

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

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

In the Hermes spacecraft or the perching module, there are large oxygenation machines that can break down carbon dioxide into oxygen, but the spacesuit can only carry an absorption device with sodium peroxide, and once the sodium peroxide inside absorbs the saturated carbon dioxide, the filter will be scrapped.

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

Engineers call this emergency mode "bloodletting."

If the nitrogen is released again, the system performs the final step, which is applied to pure oxygen – the equivalent of chronic suicide.

Excessive concentration of oxygen can cause damage to the lungs, nervous system and retina, resulting in a series of complications such as difficulty breathing, retinal detachment, pulmonary fibrosis, and mental abnormalities!

Now Pang Xuelin is in this state.

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

Pang Xuelin barely got up from the ground, and staggered a few steps before finding Matt Wodani fainted, his abdomen pierced by a signal receiving antenna, fortunately the moisture in the blood evaporated in the low pressure and strong air currents, leaving a viscous residue to seal the hole, reducing the leakage of the spacesuit 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, and then, according to his memory, he felt 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, and quickly pulled the antenna out with a slight force.

"Ahh

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

Pang Xuelin quickly blocked the entrance of the cave with gum and blocked the air flow that was bubbling out.

The air pressure inside the spacesuit began to rise, and Mark Vodani opened his eyes wide, gasping for breath in an effort to hold back the pain.

"Wardani, how are you? Can you hear me? “

Mark Wodani looked at Pang Xuelin blankly.

"Vodani, 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 perching cabin more than a hundred 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 front of the perching pod step by step.

Fortunately, the perching pod withstood the sandstorm and remained intact.

Pang Xuelin opened the side hatch outside the airlock, carried Mark Wodani in, and waited for the air pressure in the airlock chamber to stabilize, and then opened the inner hatch again.

"Hoo ......"

As soon as they entered the perching module, the two collapsed to the ground, and Pang Xuelin quickly took off the helmet of the spacesuit, and helped Mark Vodani take off his spacesuit as well.

"Thank God, Pong, we ...... We're all alive! “

Mark Vodani gasped for air, rejoicing.

Pang Xuelin said: "Vodani, are your wounds okay?" ”

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

"Wait a minute, I'll take care of it for you!"

Pang Xuelin took off his heavy spacesuit, helped Mark Wodani take off his spacesuit, and then cut open his T-shirt that had been stuck to the scabbed blood, revealing the scarlet wound inside.

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

Finally, Pang Xuelin put a box of antibiotics in front of Mark Wodani and said, "Here, just take it for a few weeks." “

Mark Wodani looked at Pang Xuelin and smiled bitterly: "Pang, how many more weeks do we have?" In this hellish place, if the oxygenator breaks, we will suffocate to death, if the water circulation device fails, we will die of thirst, if the perch leaks, we will be blown up, and even if none of this happens, we will starve to death in the end! Just before entering the perching module, I found that the MAV (Mars Liftoff Vehicle) was missing! They must have thought we were all dead and evacuated ahead of schedule! ”

Pang Xuelin said: "Watney, this is not to blame them, there are regulations in our mission that if a teammate dies, their bodies must be abandoned on Mars, so that the return load of the MAV can be reduced and the fault tolerance of the system can be increased, in that case, they have no choice." As for how to survive next, it's man-made, believe me, we will definitely have a way! ”

Having said that, Pang Xuelin was also a little anxious in his heart.

In the movie, Mark Voodany did survive after a lot of hardships in the end, but this time it was different, this time, there were two people on Mars, and the amount of various resources needed to be consumed was twice as much.

And in the movie, the MAV prepared for Ares IV had to unload a lot of equipment to reduce the empty weight because it needed to go into the same orbit as Hermes.

Even so, at the time of the docking in space, Mark Watney almost died in space.

Now there is one more person, and only one person can return to Earth in a MAV, which means they must be prepared to live on Mars for a long time.

Of course, hope is not impossible.

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

In the movie, the Ares program is a mission proposed by NASA, and in order to cater to the Chinese market, it specially added the scene of the China National Space Administration helping NASA rescue.

But in a world where the Ares program is beyond the reach of any country because it requires trillions of dollars in investment, including the geosynchronous orbit space station and the Hermes spacecraft, it has become an International Astronautical Federation-led project.

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-3 mission team is composed of astronauts from China, the United States, Britain, France, Russia, Italy, Germany, and Japan, with Pang Xuelin from China and Mark Watney from the United States.

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

In Pang Xuelin's memory, the Chinese payload of this mission was loaded with a lot of bread worms, fungal spores and plant seeds used to test space reproduction.

Pang Xuelin's eyes couldn't help but light up, it seems that next, he has 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 about it so much, we must have other ways, now let's eat something first and sleep for a while!" ”

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

Pang Xuelin laughed, in order to adapt to the different tastes of astronauts from various countries, each NASA has contributed its own unique space meal, and Gong Bang Chicken has become Mark's favorite food.

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

The two devoured it.

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