In this era, the power of technology has long surpassed the so-called magic and the spells of practitioners, flying is not the patent of masters, and the moon landing is not a dream, it is irresponsible to say that even if the Apollo 11 spacecraft in 1969 is a complete studio live broadcast, it does not prevent people today from landing on the moon more easily, but this ease is relative to a few decades ago, the cost of a moon landing is enough to make more than one million people in developed countries eat for a long time, Therefore, for scientists who do not need to land on the moon for field investigations, such as Mei Li and Renzi, there is no chance of landing on the moon in the foreseeable decades.

"Let me emphasize again, the person in charge of this moon landing program has had the experience of executing the moon landing program once, but this time is completely different from the last time, and it can be said that the experience of the last time is almost useless this time," squatting in the middle of the vacant space in the living room, I placed many of the summoned equipment in order, waiting for a while to assemble and debug, "Patty, is the main initiator of our moon landing program, and is also the chief planner, the chief computing task leader, the deputy executive, etc., etc., you haven't seen her yet, But don't forget that she should be called Pache Li? Professor Norregi, maybe she may not be more proficient in cutting-edge theories than you, but most of the research fields in the past few hundred years are within her guard, and you can imagine her as a very powerful old professor. ”

"Professor Magtroyd, may I ask a question?" Miss Renko raised her hand like a student.

"Please."

"Is Professor Norregi, an old professor with the same youthful appearance as you?"

"She doesn't necessarily care about her age, but it's best not to ask people in person," I said, "including me!" ”

"Yes, I'm sorry! I'm sorry! ”

"Lotus seeds!" Miss Melly glared at her friend.

"Hey, hey."

"Don't talk nonsense, let's help, Miss Alice said very hard."

The equipment I am assembling is a disposable space jet, the design and construction are simple and practical, and it is one of the results of Miss Patty's wisdom, because it is simple and has been constructed with alchemy in advance, and it is not difficult for me to summon it and assemble it according to the drawings I know by heart, but its parts are huge in appearance - the finished product will be nearly three meters high, two meters wide and one meter thick - which makes it difficult for girls like Melly and Miss Renko to assemble it.

In other words, Patchy thinks that although our moon landing program does not have any special secrecy requirements, it is necessary to alarm as few people as possible, especially some of the Gensokyo residents who are particularly fond of making fun, and they are very easy and good at causing trouble, so Patchy has set the final location for the completion of the jet in my apartment outside. In addition, the movement of refining small parts will become weak, and by the way, in order to keep my summoning passage as small as possible, and finally to make it easier to find possible faults, the jet is designed to be assembled instead of a seamless whole.

Let them work together to pass small parts, gadgets and small parts on behalf of the dolls, so as to alleviate the embarrassment of the two female college students who can't do it, and finally they are busy for an hour before carefully assembling the jet.

"By the way, Alice-chan, how the hell is this behemoth going to be used?" Miss Renko circled around the oddly shaped metal structure twice, and then asked.

"Well, it's used to provide acceleration and adjust direction after going to heaven."

"Oh! Is it a lander? ”

"It's not just the lander, I should have asked Professor Patchy to explain, but it should be late for her to arrive, and I don't have time to say much at that time, so let me introduce the moon landing process."

The two female college students knelt on the floor and listened attentively like good obedient students.

"First of all, the four of us will be transported to space thousands of kilometers away from the moon."

"I have a question!"

"Say."

"Teleportation, is it the legendary magic teleportation?"

"Probably, yes."

"Why don't you just teleport to the surface of the moon?"

"Because of the relative velocity."

"Oh!" Miss Renzi was keen, "That kind of magical teleportation doesn't change our speed relative to the moon?" ”

"That's right, it's Miss Renzi," I said, "If it's the most primitive magic teleportation technique, the momentum after the movement may change due to the change of direction, but if you look at the speed alone, it's almost the same." ”

"Alice means," Merry said, "the rate at which we arrive in outer space is the same as the rotation rate on the Earth's surface, which is much smaller than the rotation rate of the Moon, and if we set the teleportation point directly on the lunar surface, we will either be 'hit' in the face by the Moon, or we will see the Moon move away at a very fast speed. ”

"That's right, ah, the possibility of being hit is much smaller than seeing the moon and moving away, but for the sake of safety, you still have to place the teleportation point behind the earth and the moon, more than 2,000 kilometers away from the lunar surface, where the gravitational interference of the moon will be smaller, and the error will be correspondingly reduced, so as to facilitate operation and prevent the teleportation from being disturbed and drifting to the bottom of the moon and causing terrible consequences."

"Oh! Then that's when this space jet comes in handy! Lotus seed knocked on the palm of her hand and said.

"According to the principle of efficiency," I said helplessly, "our teleportation point should actually be placed in a position where the moon is in orbit a few minutes later, so that when we appear in space, we can see the moon coming head-on, and the use of ejectors is the most simple and efficient - just spray exhaust gas at the moon and the earth at the same time, prevent it from being captured by the earth's gravity, and slow down our landing on the moon's surface." ”

"But it's still the same problem, if there is a slight glitch, there is a good chance that we will hit the surface of the moon at the speed of the moon's revolution." Melly added.

"Yes, so when it comes to orbit adjustments and lunar landings, safety comes first, efficiency comes second—so we don't think about placing the teleportation point in front of the moon's orbit, which would take us a long time to catch up with the moon -- in short, Professor Norreki will have plenty of energy, including the energy to return home."

"Ahaha, that's good, we're not picky at all." Miss Renko laughed and said that she and her friends didn't care about efficiency, or even safety to a lesser extent.

"Well, what I want to ask, actually, how does that magic teleportation work?" Melly's focus is formal, "With the current level of human technology, it is inconceivable to move from this point to another point even if the spatial distance seems to be very close, without moving through three dimensions." ”

"Ah...... This is too cumbersome to explain, in fact, I don't understand it very well, although I have been using it very skillfully," I scratched my head and replied, "The so-called teleportation magic was inadvertently created by a not-so-famous magician many centuries ago, no, it is more appropriate to say that it was discovered and used, for magicians, nothing in the whole world, this universe can be created, everything is discovered, no matter how low the probability of its natural birth is, For example, hundreds of kilometers deep in the earth, somewhere happened to be squeezed out by geological movements, and a piece of FC game card chip stored in Super Mario was squeezed out. ”

"Ahaha, I understand, Melly's minor often talks about similar topics of gods, and the relationship between creation and discovery is left alone, it won't work out anyway."

Miss Usami was glared at by her friend again.
