History of Human Space Exploitation

Chapter 39 Flying close to the ground 3 Survival guide for unmanned planets

After waking up on the bed of the bedroom in the dark tone, overlooking the southern horizon of the star Thorpasia, I found that this familiar planet was no longer the same as usual.After five hours of deep sleep, I brushed my teeth in the bathroom and looked in the mirror at my face, which was no longer as dusty as yesterday, but still familiar.

At the same time, I am also thinking about the plan that will definitely bring me back to the civilized world in the next few months.

I grew up hearing about Ms. Gu Lanlan's deeds. Although I can't go down in history with the groundbreaking deeds, I strive to make everything perfect. Naturally, I can't let the irresponsible behavior of those conservative captains make the world record-breaking I'm stuck dead on this uninhabited planet.Survive, return to the civilized world, and let my legend not become a negative teaching material for "reckless" behavior in some satirical publications. I must let the people in the galaxy cluster know that I can fly through [-] in [-] hours. The hero of [-] kilometers will definitely be able to travel through the starry sky and reunite with his supporters.

Survival Point [-]: Try your best to get outside help.

When I was still on the space station, I saw that the Benares, which was supposed to carry me away from Solpasia, had become an almost indistinguishable spot of light. The whole supercluster followed me live for more than 30 hours. Hundreds of millions of viewers already knew about the irresponsible behavior of the shipping company.When my eyeballs became wet gradually, but those tears did not fall due to the zero-gravity environment, all the audience saw the grievance in my heart.In the next few hours, the artificial and intelligent customer service of the shipping company were busy with the complaints, accusations and even abuse sent by the entire galaxy cluster.Even the star zone government, which has done its best to the evacuation plan, was "greeted" by more supporters who I don't know.

When I was still rummaging through various restaurants, supermarkets, and drugstores in the city center, the credits donated to my account by supporters of the entire galaxy group were enough to charter a private spaceship. Five round-trip sailings were made between trips.Of course, no shipping company or individual adventurer would take such a big risk to pick me up here even if I paid a hundred times the joint credit.Because the most fundamental reason for this evacuation of the planet is that two years ago, the No. 1-17-31-5 star tunnel leading to this planet had a lot of changes that never happened in other places, and it happened in the following time Serious problems such as star tunnel shrinkage and structural fluctuations have been eliminated.If the tunnel is not evacuated in time, assuming that the star tunnel collapses or annihilates, the people at this end of the star tunnel will be separated from the nearest inhabited planet by millions of light years.

Although some supporters expressed their willingness to come to Sol Pasia for me, I firmly rejected their offer.As a "battle-hardened" racing veteran, overcoming adversity is an essential element of nearly every backcountry ride we have to face, and what our billions of supporters love is what we have always conveyed and unyielding.

Although very reluctant, under the pressure of supporters, the shipping company is willing to send one of their rescue spacecraft to wait for my arrival within one AU of the entrance of Star Tunnel 1-17-31-5.Of course, the premise of this is that before falling asleep, I spent almost an hour briefing the entire galaxy cluster on how I will take actions in the future, how to create a ship that can be compatible with the existing resources and conditions of this planet. Rescue craft that the spacecraft meet within six months.The shipping company's guarantee is enough for me, and the rest depends on whether my actions in the next period of time can be worthy of the opportunities everyone has won for me.

Survival Point [-]: Plan food consumption under the condition of limited food supply.

Based on my height of 173 centimeters, weight of 67 kilograms, and my age, which just passed my 29th birthday five months ago, a simple calculation shows that my daily basal metabolism is about 1500 kcal.Of course, from my previous speeding experience, if I need to do a lot of activities every day, especially if I need to work hard every day for survival in the future, my daily energy intake should not be less than 2000 kcal.

Yesterday I drove the Burning Bloodblade to search for the trivial leftovers in various stores, counted and weighed the leftovers in these places, odds and ends, only half or quarter of a package of the following foods:

meat:

203 kg of frozen pork;

97 kg of frozen beef;

Frozen mutton 101 kg;

251 kg of frozen fish;

153kg frozen chicken (including turkey);
133 kg of frozen duck meat;

71 kg of frozen goose meat;

The total net weight of canned meat is 150 kg;

Xuanwei ham 89 kg;

Spanish ham 61 kg.

The total amount of all meat is 1309 kilograms, and these frozen pork, beef and mutton are almost all bone-in meat products supplied to merchants.I cut and inspected every kind of meat yesterday, and I can basically calculate that if I remove the bones, I can get about 1200 kilograms of clean meat.If 150 grams of cooked meat is processed per day, that is, about 230 grams of raw meat is required for processing, these meats can support my intake for 14 years.

Fruits and Vegetables:
237 kg of fresh vegetables;

359 kg of frozen beans, corn, mushrooms, etc.;

371 kg of fresh fruit;

The total net weight of canned fruit is 289 kg, and the total weight of all fruit and vegetable supplements is 1256 kg.

These fresh vegetables and fruits cannot be expected to accompany me for more than half a month, so according to my search for knowledge on long-term food preservation methods, I will pickle all these fresh vegetables with sugar or salt for long-term preservation.At the same time, I will make all those fresh fruits into jam and puree, and use crude allicin made from garlic found in restaurants as a natural preservative, vacuum and store.In this case, the big meal I had just arrived at the apartment yesterday should be the last meal with fresh vegetables and fruits in the future.However, in order to survive, this desire for sex should of course be given up first.

Speaking of pickled vegetables, I think of a long, long time ago, when I was young, we chatted with a holographic projection of a distant relative, and the uncle talked about some interesting things in ancient times.That should be in the first half of the fifteenth century AD, during the Yongle period of the Ming Dynasty in ancient China, the great navigator Zheng He led seven voyages with the best fleet in China at that time. It is said that the fleet reached the coast of East Africa the farthest time.

What is the relationship between Zheng He's voyages and my pickled vegetables now?It matters a lot.It is said that at that time, no matter in Europe or Asia, an important problem that plagued ocean voyages was sepsis and night blindness caused by seafarers' long-term lack of vitamins.Judging from the records, almost all navigators at that time used sugar or salt to process vegetables or fruits, so that these life-saving foods during the journey could be preserved for a longer period of time.

And Zheng He himself, or the place where Zheng He was born, has been extolling the uniqueness of people making pickled vegetables from later generations to today's universe with trillions of people.Although as far as the current administrative division of the earth is concerned, there is no administrative region smaller than 100 million square kilometers, but the ancient place names from large to small such as Yunnan-Kunming-Jinning-Kunyang are still commonly used by people living here.This place called Kunyang is the hometown of Zheng He.

Walking forty to fifty kilometers south from Kunyang, you can reach Beicheng, which belonged to Yuxi at that time.From Beicheng to Kunyang, an area where mountains and small basins are mixed, delicious pickles have been carefully produced for 2000 years.In the words of food critics, although everyone knows that when making pickles, no oil or meat can touch them, but the vegan pickles made with bitter herbs here can make people feel "oily".From the similar vegetable pickling process in other places, it is very difficult to achieve such a look and feel of vegetables.

I think there is reason to believe that, as the leader of seven ocean voyages, Zheng He certainly knew how far away from land for a long time, and at the same time away from a reliable source of vitamin supplements, would affect the voyage.In a big way, this will make the plan of Emperor Yongle's world guest server not go smoothly.Speaking from a young age, Zheng He was not allowed to see these brothers who have been in the same boat for a long time succumb to illness because of such problems because of the comradeship developed in the army since childhood.Therefore, I have reason to believe that Zheng He, who is familiar with the beauty of pickled vegetables in his hometown, must have brought such a method, or such relevant personnel, on the treasure ship.

From the past eating habits, vegetables and fruits are not my favorite food, but I still insist on eating these essential nutrients for the human body every day.Considering that it is impossible for me to find a doctor for a long time in the future, I adopted the advice sent by supporters through the communicator: eat all vegetables and fruits, even those that have been pickled.If I eat 100 grams of cooked vegetables or fruits every day, I generally need 500 grams of lettuce to process. In this way, all the stocks can ensure that I have enough vitamin intake for six and a half years.

staple food:
537 kg of flour;

719 kg of rice;

321 kg of wheat noodles;

Pasta 397 kg;

Macaroni 673 kg;

Buckwheat flour 291 kg;

Compressed biscuits 213 kg;

Biscuits (ordinary biscuits, animal biscuits, puffed biscuits, etc.) 187 kg;

103 kg of fresh bread;

97 kilograms of cake, a total of 3538 kilograms.

Obviously, the most perishable cakes and fresh bread should be the first things I should tackle for a short time to come.

In fact, what I usually hate most is the staple food, but from a scientific point of view, the staple food has been a habit of human beings for hundreds of thousands of years and has formed the main food for hunger, so it is still necessary to eat some every day.Assuming that I eat 10 grams of processed and water-containing staple food every day, the raw materials need about 500 grams, so excluding cakes and fresh bread, these staple foods can keep me alive for more than 250 years!

To sum up, if the time it takes for me to build a spaceship that can escape here is basically controllable, as long as I plan a reasonable and quantitative diet every day, these foods will support me to board my new "space version of the burning blood blade" No, it will not be a problem to support me to sail in space for a while.So it's all a question of whether I'll be able to maintain my health and build a usable ship in a reasonable amount of time.

Medicines: In order to avoid misleading readers in the use of medicines and health care products in unprofessional text, this paragraph was omitted during publication.However, since almost all the people and businesses evacuated from Solpasia have received the relevant destination planet’s strict inspection of imported drugs, especially the inspection of unsealed drugs, so in the medicine box of every family on the entire planet, there are The medicines used for emergency before the owner left, and various health products that everyone often eats are stored intact.It should not be too much to describe my excellent physical fitness with a certain word "national defense physique" that has been lost in the fog of history.Of course, the medicines used to prevent various possible diseases must be prepared and readily available at any time.

Survival Point Three: Accurate Calculation
I'm not the "hope for the best, plan for the worst" kind of person, but before heading out from Potato Town, and even before I started planning this drive-thru a few months ago, I had somewhat considered what would happen if there was a mechanical failure in the middle Or what should I do if I fail to catch up with the spacecraft due to unavoidable accidents such as natural disasters.As far as the current situation is concerned, if the shipping company really sends a rescue ship to patrol and wait for me near the entrance of the Star Tunnel on 1-17-31-5, I will travel from the Solpathia Space Station to La Grande in the Star Tunnel Near the sun point, there is a distance of about 29 AU to travel.

29 astronomical units are naturally insignificant in today's human footprints of hundreds of thousands of light-years through star tunnels, but for me to build a spacecraft on such an uninhabited planet and fly there, It's really hard.One astronomical unit is the distance from the earth, the home of mankind, to the sun, which is about 500 light seconds, or about 1.5 million kilometers. 29 AU is approximately 44 billion km.

Based on the above calculations, and according to official estimates, the most likely collapse time of Star Tunnel 1-17-31-5 should be 8 to 12 months from now, and from a safety point of view, I'd better It can reach the vicinity of the Star Tunnel within 6 months, pass through the Star Tunnel and board the rescue ship of the shipping company. With a distance of 44 billion kilometers, in 6 months, I need to make my aircraft reach a speed of 280 kilometers per second, and if you count the acceleration time when leaving and the deceleration time when it is about to arrive, it is 300 kilometers per second The speed of [-]/[-], that is, the speed of light, is the lower limit of the speed at which I can guarantee my safety in time.

According to Thorpasia's history of mining silicate gemstones over the past few hundred years, warehouses and "robot graveyards" are piled up with robots using fission batteries.From a cost point of view, mining companies are more inclined to use the battery for more than 200 years, while the robot with a mechanical body that can only be used for less than 100 years is directly deactivated, and new ones are purchased to continue serving the Taimiao.When I checked the relevant statistical documents a month ago, I already knew that there are approximately 700 million mining robots of various types existing on the entire planet, which means that I will be able to obtain no less than 1000 million from them, net A battery with a fissile material plutonium-238 content of approximately 500 grams.

According to the Tsiolkovsky rocket equation deduced by Konstantin Tsiolkovsky (К.З.Циолковский, 1857-1935), the Russian in the nineteenth century and the father of human spaceflight, I made the following Calculation: and the energy density per unit weight of plutonium-238 after the explosion (approximately 200 million joules per kilogram) and the specific impulse of the substance (8 N·s per kilogram); the orbiting space station of Solpathia Weighing about 1000 tons, it will be transformed by me into a temporary vehicle for leaving here plus a temporary residence for those six months of space travel.

To sum up, I need about 1 ton of plutonium-238 explosion as an external pulsed plasma propulsion method to accelerate the 1000-ton orbiting space station to 300 kilometers per second, and then when it is approaching the star tunnel, Another blast of another ton of fuel is used to reduce the speed to almost a standstill.

In the next two days, I found ten more advanced humanoid assistant robots in various repair shops in Huangbaota City, the capital.After programming and organizing them, I sent five of them to various robot cemeteries and warehouses to dismantle the plutonium-238 batteries; Those found foods are processed, packaged and transported to future spacecraft.

I broadcast the whole process to all human beings through the Wells information flow network that connects the entire Virgo supercluster.The number of my followers is increasing by tens of millions every day, and many companies from all walks of life have sent me invitations, expressing their willingness to cooperate with me in depth after I return to the civilized world, but I declined all of them up.

经过37天紧张而有序地忙碌后，我用无线电通知两个舱外的机器人把在轨太空站与太空电梯切割并完全分离，然后引爆了第一组裂变电池。就这样我在50亿支持者的注视下向1-17-31-5号星隧飞去。
