48 Hours a Day

Fire in space is definitely one of the things that all astronauts don't want to happen to.

In the aftermath of the Apollo I accident, NASA also redesigned and optimized the interior of the spacecraft, replacing the flammable materials in the cabin with materials that would automatically extinguish fire, wrapping insulating materials on the piping system and wires, correcting circuit problems, changing the atmospheric pressure in the cabin, changing the gas in the cabin from pure oxygen to oxygen nitrogen blending, changing the nylon space suit to a coated space suit with fiberglass, and enhancing astronaut training in fire handling.

Flames in spacecraft are very different from flames on Earth, losing gravity, and the hot air produced by flames burning in a free-fall state does not rise, but wraps the flames around and forms a low-oxygen, high-temperature layer.

Because of lack of oxygen, the flame spreads slowly, turns into a light sphere, and burns at lower temperatures than the Earth.

Generally, after a fire, an alarm is sounded inside the spacecraft, then the astronaut needs to put on a respiratory mask, determine the ignition point at the fastest possible speed, cut off the nearby power supply, while others use fire extinguishers to extinguish the fire, and if the fire is out of control, the astronaut needs to leave the ignition compartment, retreat to the other compartments, lock the gate, and close the air cycle fan of the ignition module.

Subsequently, Apollo XIII exploded the day after its launch, but seven astronauts on board were in critical condition, responding well, and all were safely transferred to the moon deck, cooperating with the Ground Control Center, abandoning the moon boarding plan, driving the ship to the back of the moon and successfully returning to Earth with the slingshot effect, creating the greatest miracle in human space history.

Of course, these are the last words.

NASA's fire disposal training is conducted in a confined environment of an analog aircraft and certainly does not use real fire, but is replaced by a red alarm light, requiring participants to follow the steps to perform the fire fighting process, so there is theoretically no danger.

According to the order of the names, this time it was the middle-aged man's turn to take the lead. He looked at the high school students beside him and the two walked into the simulation module.

The simulation bin consists of two parts, corresponding to the service compartment and the moon boarding compartment respectively, and the two go straight to the innermost service compartment, which is where the first part of the training begins.

Later, however, when the alarm sounded, they did not remove the breathing mask beside them as required by the manual, and the high school students quickly took off their tops and revealed a row of water bags tied to them.

Those bags are now filled not with fresh water, but with light yellow gasoline, which he stole from the warehouse.

He opened the gasoline and poured it on the cotton bags around him to simulate the flammable, and he said, “Now you can tell us how to hide the smell of this thing, lock the hatch doors, and finish the remote ignition. ”

The middle-aged man didn't answer until the high school students had poured out all that gasoline, and he also quietly retreated to the hatch door, taking out a match, wiping it, which was the only way to say, “I told you my last single competing copy had met two players who were small in the real world, to compete for the last spot, one of them had to kill the other, it was a very difficult choice, very difficult...” The middle-aged man paused, "What I didn't tell you, I was the one who did it. ”

“What?” A bad feeling arose in the mind of the high school student, who turned around and saw the middle-aged man standing at the junction between the service cabin and the lunar cabin.

At the same time, the latter threw the matches in their hands. The matches accurately landed on a bag of cotton that was drizzled with gasoline. The fire started quickly. The high school students couldn't think much of it and pulled their legs to the outside. However, the middle-aged people had successfully closed the cabin door of the service cabin.

Alarms for simulated fires in the service compartment continued to sound loud, but sounded somewhat ironic with the backing of growing fires around them.

The high school student used his milk strength to peel the hatch open a little bit, but just as he was about to see hope, he was poured a basin of cold water in his head. He saw the middle-aged man on the other side pull out the lighter and pointed at the lower half of the hatch.

As with the previous door locks, the heated part melted rapidly, but this time the middle-aged man quickly retracted the lighter, and the melted part came into contact with the ground, cooled down and quickly fixed, and connected to the surrounding area.

Middle-aged people retracted their hands, but this time high school students could no longer keep the hatch open.

“I'm sorry I didn't tell you the truth before, I couldn't hide the smell of gasoline and finish the remote ignition, I don't have that prop on me. ”

“Are you crazy?! What's in it for you to kill me? Are you going to fight with those two alone?” The high school student was sweating, there was gasoline in his water bag, the flames burned quickly, his tongue could lick his back, his face became more and more frightened, even begging the middle-aged man to open the door.

And the latter didn't move, “Who said I was going to fight two people after that?” The middle-aged man raised his eyebrows, "I do have allies, but unfortunately, that person is not just you. By the way, you can cry out for help, but the two simulation bins are very closed, and the people outside can't hear anything inside. ”

“Kill me. How do you tell the NASA people?! Do you want to go on the moon? Or did you just do it to be somebody else? You're not like that, are you?” High school students were choked by smoke and tears came out of their noses.

The middle-aged man took a few more steps back, away from the flames that spread, “Gasoline is what you brought into the simulation cabin. I haven't left the sights of anyone else since I woke up in the morning until now until the fire management training. Only you disappeared after lunch for so long, so people will think that you set the fire. As for the reason, I don't know… maybe the intensity of the recent training made you overstretched your mind, and it was possible that the candidate's successive events caused you to exceed the limit of stress. I just went to the moon cabin to train for the second part of the evacuation. By the time I found out, it was too late, and you also closed the middle cabin door. ”

“Do you think NASA people wouldn't suspect you?”

“I don't care, as long as they don't have absolute proof, they still need us on the moon for them.” The middle-aged man covered his nose with one hand to prevent inhalation of poisonous smoke, while looking at the watch on his wrist, calculating how much time he had left in high school. When there was no sound inside, the smoke in the lunar compartment was getting louder and louder, he could no longer stay. The middle-aged man ran to the door, pushed the hatch door, changed his alarmed expression and yelled, "No good, fire! ”
