The Science Fiction World of Xueba

Xi Pang Xuelin changed into a new EVA spacesuit, and the two returned to the living module to check it again.

The dome bracket used to maintain the internal pressure of the living module has fallen a few, but the problem is not serious, and it will be fine to install it.

Medicines, food, and various materials were scattered because of sudden gas explosions, but basically had little effect.

The energy and planting chambers are both closed, so the planted potatoes are temporarily preserved, and the nickel-metal hydride battery and main electromechanical equipment in the energy chamber are intact.

The main gas tank and water storage tank are both in the energy compartment and are intact.

The water circulation system bursts due to freezing, but it can be repaired.

The oxygenation machine cannot be started. Only after the living cabin returns to the pressure and temperature, the result can be known by running the habitat management system for diagnosis.

The communication system was not affected by the gas explosion because the Mars Pathfinder Landing Module was placed on the side of the rover.

因为 The main control system in the living cabin enters the dormant state due to sudden pressure loss, and the standby control system of the energy cabin is connected.

Watney could not help but breathe a sigh of relief: "Pang, thanks to your foresight, to isolate the planting and energy cabins from the living cabin, potatoes are still there, and our losses are not great."

Xun Pang Xuelin nodded, even if he was still worried.

To a certain extent, I was pretty lucky. If it was an explosion when Watney was out of the cabin, I guess I would have become an ice corpse.

"The Ares Command must have found out that we had an accident, let's report their safety first!"

Pang Xuelin and Watney returned to the cabin, and put the "Ming" code of "Peace" with Saturn stones.

Next, it took a whole day for Pang Xuelin and Watney to use the remaining main parachute film of the MDV to close the blasted airlock, and then enter the energy compartment from the second airlock chamber.

备用 There is a backup control system in the energy cabin, which can control the air conditioning, water circulation, atmospheric circulation, communication and other systems of the habitation cabin.

"Repressurize the living compartment!"

Oxygen generator and water circulation system are temporarily unavailable, but spare nitrogen and oxygen tanks can be used to pressurize the living compartment to restore temperature.

Soon, under the control of Watney, a slight buzzer sounded from the compressor.

After twenty minutes, the air pressure in the living compartment recovered and the temperature recovered.

Pang Xuelin and Watney entered the living module wearing an EVA spacesuit. First, they checked the tightness of the living module and confirmed that there were no problems before restarting the control system of the living module.

The air conditioning unit is running and the communication system is restored.

Almost immediately after the communication system was restored, a large amount of information poured into the computer screen.

[9:30] JPL: Pang, Watney, satellite observed the airlock chamber 1 detached, please reply when you receive the message.

9 [9:32] JPL: Pang, Watney, the satellite observed that the airlock chamber 1 has detached. Please reply when you receive the message.

Uh ...

[10:28] JPL: Pang, Watney, please reply when you receive the message.

Uh ...

17 [17:39] JPL: The satellite observed the Morse code you placed. I hope you are all safe. Please contact us as soon as possible after the communication is restored.

Uh ...

[20:23] Habitat: Command, I'm Pang, and Watney is right next to me. I'm in good condition. I have suffered a minor injury, the wound has been treated, and the problem is not serious.

[20:35] JPL: Xue Lin, my name is Tian Mu. I am currently contacting you at the Ares China Command through Pasadena transit. Satellite data shows that the No. 1 airlock chamber is completely separated from the habitat, is it confirmed? .

[20:50] Habitat: An air explosion occurred in No. 1 airlock chamber. At that time, I was in the airlock chamber. I was slightly injured in the explosion. Upon inspection, the carbon fiber sealing material between the airlock chamber and the perch was torn. crack. At present, the power system and communication system have been restored. The energy and planting cabin doors were closed during the explosion and were not affected. The main gas tank and main water storage tank were normal. The rover, solar panel and Pathfinder Landing Module are in good condition. Some water pipes of the water circulation system are broken. Preliminary estimates can be repaired, the oxygenation machine cannot be started, and the status is unknown. Further testing is needed. Laotian, do you have any thoughts on the cause of gas explosion? What advice does the command have for our next action plan?

[21:06] JPL: The Ares III mission originally planned to perform a one-month ground mission on Mars, so the actual design life of the habitat is about half a year. According to preliminary analysis by the expert team, the carbon fiber canvas material around the habitat and the airlock chamber was aging. Repeated pressure increase of the airlock chamber caused it to overstretch until the pressure was lost, and then gas explosion occurred. From now on, it is recommended that you use the No. 2 and No. 3 air lock chambers alternately for EVA tasks. We will give a detailed list and work flow instructions as soon as possible to systematically inspect and maintain the entire canvas material. In addition, check the status of the oxygenator and water circulation system as soon as possible. These two systems are the most important. Please respond to the latest news in a timely manner.

[21:18] Habitat: Understand.

Uh ...

The 183rd Mars day.

It took a day for Pang Xuelin and Watney to systematically inspect and maintain the canvas materials of the perch in accordance with the work flow given by the team of experts on the planet. Fortunately, because the second and third airlock rooms are rarely used So these carbon fiber canvas materials are still in good condition as a whole.

The 循环 water circulation system is just that the water pipes have broken, and their spare water pipes are enough to repair.

The real bad news is that the oxygenator is finished.

Pang Xuelin and Watney are not worried about whether the oxygen is sufficient, because there are more than 1,000 liters of liquid oxygen in the main gas tank and the standby liquid oxygen tank, which is enough for them to use more than 500 Mars days.

The real question is how to deal with this carbon dioxide.

The most important function of oxygenation machine is to use molecular sieve to adsorb carbon dioxide under pressure, and then convert it into oxygen through a series of physicochemical reactions.

This gas explosion caused the oxygen zeolite molecular sieve to be completely exposed to cold air at more than 60 degrees below zero, which directly caused the irreversible change of the chemical properties of the molecular sieve.

And in this mission, in addition to carrying a carbon dioxide adsorption device that can be used by Pang Xuelin and Watney for 20 days, they did not carry oxygen molecular sieve at all.

Trouble!

In the living module, Pang Xuelin and Watney were silent.

Xi Pang Xuelin originally thought that by closing the planting cabin and the energy cabin, he could avoid the thunder point of the airlock explosion.

He did not expect to detonate another mine instead.

If you can think of one more layer at first, you may not be able to think of the impact of repeated entry and exit of the airlock chamber on the carbon fiber canvas material of the perch.

Now I ca n’t regret it anymore, I can only take one step at a time.

"Pang, what next?"

Watney was worried.

Pang Xuelin frowned: "Temporarily use the carbon dioxide adsorber spared in the habitat. This can be used for emergency use for twenty days. In addition, we have a small carbon dioxide filter of 2300 hours. You can use it for an additional 45 days. In the end, if there is no way, we use the last trick to change the air in the living room once a day. Our current liquid oxygen storage tank allows us to use it for more than 500 days and change the living room every day. The consumption of liquid oxygen in the air will increase rapidly, but it can also keep us a hundred days long. In this case, we have at least 160 lives on Mars. And ... "

"What else?"

Watney said.

Pang Xuelin said: "Wotney, we still have a lot of seeds. Do you say that if we plant large-scale green leaf plants in the living and planting cabins, is there a possibility of maintaining the carbon and oxygen water cycle of the habitats through photosynthesis?"

Watney frowned, saying, "This method is feasible, but it requires precise control of the scale of planting and maintaining a balance of carbon dioxide, oxygen, and water. This is equivalent to the establishment of a set of microbiospheres 2 on Mars, which is very difficult. Large, and you have to know that our water resources are limited. If we continue to grow other crops, it will be necessary to occupy some of the fertilizer and water originally provided to potatoes. In this case, our food reserves may go wrong! And if we make water, we will It also consumes liquid oxygen. In this case, if we fail, the time of death may come in the next three or four months. In addition, I need a more comprehensive mathematical model to simulate this microbiosphere! "

Pang Xuelin nodded and said, "I'll get the mathematical model. Let's explain to the earth our current situation!"

Communication was established again ~ www.readwn.com ~ Habitat: Command, Watney and I have completed preliminary inspections of the damage of the pod. The canvas materials in other areas have not been found for the time being. The water circulation system can be repaired, but we encountered a Big trouble, irreversible changes in molecular sieve of oxygenation machine, lost the ability to adsorb carbon dioxide, we can only use a backup carbon dioxide adsorber, but only 20 days of use time, in addition, we have 2300 hours of small carbon dioxide filters, Would let me and Watney live for more than forty days, that is to say, after more than sixty days, Mars satellites can observe our bodies. Watney and I have initially drafted a plan that will be transmitted to you as a file.

19 [19:45] JPL: I'm Vinkat Karp, and I'm currently talking to you through a Pasadena transit in Houston. Pang, I'm sorry to hear such news. I hope you and Watney remain calm. Our team of experts will come up with a feasible rescue plan as soon as possible. Please believe that, before the last minute, we will do our best to expand to you. Rescue!

[19:57] Habitat: Thank you, Dr. Carp, and hope to hear from you soon.

Uh ...

[21:35] JPL: Pang, Watney, the team of experts initially agreed with your plan, but we need an accurate mathematical model to be delivered to the supercomputer simulation in order to give a more feasible plan, I ca n’t promise You have an accurate time, but will do your best. In addition, according to the latest orbit calculations, we will launch supplies in two months and reach Mars within 500 solar days as much as possible!

[21:53] Habitat: Yes, Watney and I will submit the corresponding mathematical model within one week.
