Jiang Yicheng piloted the shuttle into a landing orbit in the opposite direction of rotation to the spacecraft's synchronous orbit, and the intended landing site was set in the middle of the continent at the equator of "Lanper" (1).

During the landing, Jiang Yicheng tied himself to the shuttle seat with a seat belt, and fixed the helmet on the seat pillow with an electromagnetic buckle to avoid irregular vibration and sprain his cervical spine in the process of passing through the atmosphere.

Then she turned back to the drone camera, smiled at her audience in the solar system, and said, "Now that the landing orbit has been set, and we are waiting for the landing, I will introduce this channel first." This is mainly to let new friends know about my mission, and I will try to introduce it as quickly as possible so that old friends will not be too annoying. ”

Barrage: An orange classroom is on the air!

Barrage: New friends raise their hands [raise hands]

Barrage: +1 for new friends

Barrage [Red]: New Friends +10086

Barrage: There are colorful barrages in front, and there are newcomers [funny]

Because Jiang Yicheng's live broadcast of survival is also a popular science program, the audience watching this is generally relatively friendly. She continued: "This channel is about an alien survival challenge for a week, and then I'm going to survive on the surface of this planet for seven days with just a camera drone and my protective suit. After seven days, the ship will automatically send a shuttle to the surface, and I will take the shuttle back to the ship in synchronous orbit. ”

"I would like to remind you here that I can communicate with the spaceship AI throughout the survival challenge, so it can be said that it is relatively safe, and you must not try dangerous behaviors without safety guarantees."

Jiang Yicheng glanced at the control panel of the shuttle between words, and after confirming that all parameters were normal, he said to the camera with a smile: "This is the first time I have challenged to survive in Lanpo for a week, and to be honest, I am still a little nervous...... Blue Amber is a completely unexplored planet, which means that it has no human facilities at all, its life system is different from that of humans in origin, and its atmosphere is not suitable for human breathing. ”

"So I'm wearing this 'Golden Wheel-3112' protective suit now-" Jiang Yicheng tugged on the trademark on the protective suit so that it could be seen more clearly on the screen, "Haha, a friend left a message saying 'just a meal', yes, this is the endorsement given by the brand." ”

"This suit should be regarded as a professional sealed and compression-resistant protective suit, and the internal carbon fiber tube bracket can adapt to the pressure from vacuum to 50 atmospheres (2), which is enough for me. After all, we are challenging habitable planets, and the natural conditions for undeveloped planets that can be identified as habitable planets are still relatively good. ”

"Then in addition to the protective suit, I started taking live combination bacteria a month before I came here, and I had an oximeter implanted in my chest." Jiang Yicheng continued, "Friends who are familiar with this channel should know that these two things are the regular preparations of interstellar explorers, and they need to be operated in the hospital with a work permit, so there is no endorsement or endorsement." ”

"The oximeter is connected to the pulmonary artery to oxygenate the hypoxic blood, so that you can avoid breathing the planetary atmosphere, and an oximeter can last for about fifteen days, so it is definitely enough."

"Live Compound Cultures are bacteria that have been selected to break down various carbon backbone organics and produce glucose, amino acids, and unsaturated fatty acids. This is also a must to survive on an unexplored planet......" Jiang Yicheng glanced at the barrage and then smiled, "There is a message saying that this is very similar to the probiotics that everyone usually eats, yes, it's pretty much the same." ”

"We all know that carbon is relatively easy to form (3) and at the same time has a very rich valence element. Generally meet our human standards, and habitable planets with origin life, its native organisms are made of carbon skeletons. However, chemical evolution has a certain randomness, even if it is all carbon skeleton, as long as there is a difference in chirality, we humans as higher organisms will not be able to digest it. ”

"But even though we can't digest it, we can let bacteria and the like digest it, and then convert it into nutrients like glucose for us to absorb. In this way, although the energy conversion efficiency is relatively low, the interstellar explorers can rely on this little energy to survive in the alien planet. ”

She glanced at the control panel again: "That...... This landing time is more, because the rotation of the blue amber is relatively fast, the 'day' is 660.3 minutes, which is exactly 11 hours, and the reverse landing orbit will be a bit long. ”

"So I'll just introduce a little bit more, everyone should know about nylon bacteria (4), right? Belch...... It doesn't matter if you don't know, nylon bacteria are bacteria that have evolved the ability to break down nylon. The bacteria in the compound bacteria are similar to nylon bacteria, except that they are not naturally evolved but artificially mutagenic, and can decompose a variety of carbon skeleton structures. ”

"By the way, I also want to say that the helmet I am wearing now is also Jinlun's - cough, endorsement must be said, this is an industry regulation." Jiang Yicheng knocked on his helmet, "Because there is an oximeter, the helmet only plays the role of isolating the outside air." One of the great things about this helmet is that it has a small compressed air chamber that allows for immediate ventilation after the helmet is closed. ”

"But to mention here, I personally don't produce these products, and I don't know how they compare with products at the same price in the market, so if you want to buy, you still have to consider your actual needs."

Barrage: Conscience One Orange [Than Heart]

Barrage: Let her be cha, let her cha!

Barrage: One orange is more than just right, mom loves you [Rose]

Barrage [Yellow]: Don't Male Mom [Funny]

Barrage: Sister One Orange begs for the Amway shuttle brand!

Jiang Yicheng glanced at the barrage and explained with a smile: "A friend asked me about the brand of the shuttle - in fact, I used to be a spaceship designer, and I designed this shuttle myself. And then the ship was also designed by myself......"

"Ask me why I switched to this as a spaceship designer? Well, this story has actually been heard by many old friends. ”

"I used to be a spaceship designer, and I had a design institute that specialized in long-distance spacecraft - in fact, it is quite famous in the industry, and you can definitely find it on the Internet. Two years ago, I took a big order, and then I smashed it, and a lot of money I borrowed was wasted, and my reputation became very low. So I can't take out another loan, and I have to pay off the debt, and I think that I have a long-distance spaceship in my hand anyway, so I can just be an interstellar explorer, and by the way, I will broadcast live. ”

Interstellar explorers are a veritable marginal profession of human civilization. Don't look at the name "interstellar exploration" is quite nice, in fact, another more appropriate name for this profession is the so-called "space gold rush".

"Space gold panning" is not for gold, but for resources in a broad sense. Their job is to drive the spaceship to a star field far away from the solar system to find resources available on celestial bodies. And "space" is so empty, and there are so few celestial bodies with resources that can be used by the current human race. The probability of an interstellar explorer encountering a truly valuable celestial object is no different from hitting a lucky one. Therefore, people engaged in interstellar exploration have signed contracts with the "agency", and the income of a voyage is calculated according to the scope of exploration, and the recorded celestial resources are owned by the "institution" regardless of their value.

So the interstellar explorer is also a veritable wage earner - who is not a wage earner in this world now? It's possible to make money faster by streaming, but it's all a matter of luck, and you need to do things that normal people wouldn't do, such as surviving on the surface of an unexplored planet for a week without supplies and almost without protection.

But for Jiang Yicheng, it's thankful to have money to make. After the dissolution of her spaceship design team, the capital chain was broken, and she had to pay raw materials and employee salaries, etc., and owed the bank more than 20 billion yuan in total (5). Now she has to repay about 80 million a month, which means that she has to do at least one survival live broadcast every month to barely make ends meet.

She didn't dare to think about how much money she still owed the bank, so she quickly focused on the live broadcast work: "By the way, friends, I'll talk about the time delay before I land." ”

"My camera is a communication wormhole directly connected to the spacecraft, and the distance from the ground to the spacecraft produces a negligible delay of tenths of a second. At present, the distance between the earth and the moon is about 40 kilometers, and the delay between the moon's friends and this side is more than one second, and the back and forth is more than two seconds. ”

"The distance of Mars is almost one astronomical unit, and the asteroid belt space station group has about four astronomical units (6), this distance leads to a long time delay, and I can't see the messages of friends in Mars and the asteroid belt in real time, but I will sort out all the messages after I go back, and pick out some to respond."

Exegesis:

(1) This is due to the fact that the spacecraft orbiting in synchronous orbit is equivalent to stationary above a certain point at the equator.

(2) Fifty atmospheres: 50atm is not much, which is equivalent to the pressure of 500 meters underwater.

(3) The abundance of carbon in the universe is generally high: stars with a mass greater than 0.5 solar will have helium combustion, and the fusion of three helium nuclei will produce a carbon nucleus (the intermediate process is omitted), so the production of carbon is relatively common.

(4) Nylon bacteria: A bacterium discovered in a sewage pond in Japan in 1975, which produces PET decomposition enzyme (PETase) due to frameshift mutations, which can decompose nylon for energy. (I don't know if anyone here knows @nylonbacterium)

(5) Please note that there is inflation.

(6) Using Pallas as a reference, the data simulation is from Stellarium.
