Estimation of Lunar Surface Shock Effects and Optimization of Damping Scenarios: A Case Study in Response to NASA's Request for Proposal
The aim of the present work is to respond to NASA's request for proposals on understanding and reducing the adverse effects of landing or take-off on the lunar surface. Two initiatives can be developed. The first is that of a natural satellite with no atmospheric layer, which suggests that any particle will fall at the same speed in the absence of any air friction effects. A rocket could land without any major impact. The second is to take into account an atmosphere above the lunar surface. Terrestrial particles are likely to form and remain in suspension for some time. To remedy this situation, six scenarios were explored. Two alternatives have emerged from these investigations:
The first is the installation of a device (rocket accessories) to reduce the effects of the fuselage during ascent;
The second is the integration of new features into the rocket, such as vertical fuselages or a folding and unfolding locomotion slide to move the dust cloud away from the formation zone.

1. Introduction
In space, granular and rocky materials are subject to both gravitational and atmospheric circulation forces during a disturbance. The latter derives its ancestral force from temperature, i.e. solar radiation [1]. Without the existence of an atmospheric layer and the spherical shape, atmospheric circulation modelling would certainly have taken a wrong turn. On the lunar surface, the conditions of reasonable distance from the solar source (i.e. 150,000,000 km [2]) and sphericity can be an asset for comparison with the Earth. In the absence of a layer of air enveloping its surface, the equilibrium of a homogeneous spatial temperature distribution around a mean value cannot be justified on the lunar surface (unlike Saturn's moon Titan). For this reason, winds would not exist on the moon, nor would a sandstorm or cyclonic season. In this case, the moon's sphericity would only be useful in the vertical meridian zone, to facilitate a short-distance landing, unlike at the north and south poles.
The aim of this first work is to contribute to a philosophical understanding of how granular and rocky materials of all sizes can behave on the lunar surface after being exposed to the landing or take-off force of a rocket weighing several thousand tonnes.
Until now, rocket take-off and landing missions have been carried out in vertical motion and are assumed to have the same impact effect on surfaces, even if the weight of the re-launch is slightly different from that of the ascent, due to the variation in the weight of the on-board fuel.
The gravity field on the lunar surface is calculated at 1.62 m/s2 [3], i.e. a gravitational acceleration some six times lower than on the Earth's surface (9.81 m/s2 [4]). An Artemis rocket with crew and cargo can weigh at least 2,000 tonnes [5]. The amount of fuel and its weight are astronomically proportional to the mission's round-trip distance, engine efficiency and on-board engine technology.
For a landing mission, there is a threshold altitude at which a surface covered in dust and rock is touched by the propulsion force (e.g. 39,144 kN [5]), which keeps the weight of the craft suspended in the void and slows down gravitational attraction. In principle, the slower the ascent, the greater the impact on the surface. Contrary to what happens on Earth, the return to normal after an ascent impact on the lunar surface for a landing mission would be faster with the same time interval, whatever the characteristics of the seed and rock lifted. For rocks thrown up with kinetic force, the impact does not seem to affect the craft directly or indirectly. On the other hand, the stronger the gravitational field, the faster the rocket's ascent is expected to be, so as not to over-consume on-board fuel, while avoiding a hard landing that would disable many of the craft's functions and features. Given the Earth's gravity field, a lunar landing mission would be around six times slower and six times more fuel-efficient.
In addition, thanks to the Lunar Atmosphere and Dust Environment Explorer (LADEE) mission, recent studies [6,7] have changed our perception of the Moon, confirming the presence of a lunar atmosphere, albeit almost negligible compared with that of the Earth. The sources of this atmosphere can be multiple: meteorite bombardment, rock decomposition, solar eruptions, etc.
When examining the lunar atmospheric layer, it will be vitally important to understand the atmospheric pressure with the elements that make up the lunar atmosphere, mainly argon, helium, sodium and hydrogen. The shock effect on the lunar surface would be based essentially on the interaction potentials of these latter chemical elements.
With a view to providing some answers to NASA's project, the remainder of this article is organized as follows:
- First, we analyze an approach in which atmospheric cover is neglected.
- Secondly, we counter this approach by proposing scenarios and draft solutions.
2. Analysis of the Artemis landing mission: case without lunar atmosphere
The riskiest incident on a lunar mission would not be the suspension of rocks and other particles in lunar space, since all rocks, whatever their size, would fall at the same speed. In addition, the spiral effect observed in the drag of turbojet aircraft would not exist on the Moon, due to the absence of air particles. What's more, the projections caused by the blast effect on landing will be projected in all directions, from the source of the ascent to extremities whose distance is proportional to the force. In this context, the risks of a mission to the Moon are much lower than on Earth. Impact with the surface does not directly or indirectly endanger the spacecraft, except in the case of nearby installations.
Prospecting the lunar surface and its stiffness composition would appear to be an indispensable asset in the study of an initial landing strip. Meteorite impact zones can represent a major hazard for rocket landings and take-offs. Projections of elements from the lunar surface can cause fallout on the rocket, due to its specific funnel shape at the point of impact with the lunar surface. The geological characteristics of the more rigid zones should be compared between the Moon's surface and that of the Earth, in order to identify an optimum zone for reducing the impact of rocket engine propulsion.
3. Analysis of the Artemis landing mission: case with lunar atmosphere
In this section, we analyze five scenarios whose feasibility seems to be approaching with the maturity of current technologies. This section takes into account the importance of the lunar atmosphere and proposes solutions to avoid complications with the dust cloud during ascent.
3.1. Scenario 1 : absorption
In the scenario shown in figure 1, at a precise and optimal altitude during ascent, the rocket detaches a circular capsule (which can be unfolded and folded), absorbing the propelled granular and rocky materials and releasing the absorbed air by filtering. This device is designed to withstand the extreme temperature of the fuselage, and to incorporate artificial intelligence to identify rocks according to their respective risks. The prototype shown in figure 1 is essentially based on the capacity and performance of rock and dust aspirators, which will be released at a given altitude before landing. The parameters of these aspirators will be designed to ensure a safe landing of Artemis on the lunar surface.
Figure 1. Circular vacuum cleaner for dust and granules.
3.2. Scenario 2 : parachuting
The scenario described in figure 2 involves parachutes being released to trap granular and rocky material rising towards the summit during ascent. The number of parachutes used may vary to optimize landing safety. The characteristics of these parachutes must correspond to the results expected for the safety mission. In addition, each parachute must be equipped with a device that detects and predicts the area most affected by the fuselage explosion, in order to optimize deployment on the priority area. This requires the use of artificial intelligence. The feasibility of such a device seems certain to reduce rock and granule heave, as well as the formation of dust clouds.
Figure 2. Case of a parachute trapping the effects of shock.
3.3. Scenario 3 : artificial vat
The scenario in figure 3 describes a prototype that deploys a device capable of sinking into the lunar soil (like a tomahawk missile) and deploying a kind of metal tank inside the soil. The latter is adapted to the overheated condition and will contain the blast, while sparing the lunar soil from being impacted by the blast.
This will prevent the formation of dust clouds and reduce the risk of dust impacting the rocket engine during landing [8].
Figure 3. Case of a tank sinking to the surface of the moon.
3.4. Scenario 4 : surface copper
In the scenario below (figure 4), as the rocket ascends, at a precise and ideal altitude, a slide ejects from the rocket and deploys over a wide lunar surface to serve as a landing point and avoid the lifting of granules and other rocky material. Unlike the previous scenario, this is a surface deployment with automatic ground engagement. This shows just how important automatic devices and artificial intelligence are for this mission.
Figure 4. Fold-out copper case as landing point.
3.5. Scenario 5 : fuselage horizontal
In the scenario shown in Figure 5, the rocket fuselage would have to be redesigned to incorporate a new vertical fuselage system capable of slowing down gravity. Self-deploying vertical fuselages are intended to compensate for the traditional fuselage. This approach will minimize the blast effect of the fuselage on the lunar surface.
Other modifications can also be made, including the integration of a wheel to help the rocket move away from the dust closud formation zone after landing.
Figure 5. Feasibility scenario of additional fuselage rotation during Artemis landing.
3.6. Scenario 6 : dust cover
In the final scenario of the Artemis mission back to the moon, the ship's skin should have physico-chemical properties that prevent dust from clinging to the ship. This proposal, presented in figure 6, can be based on the secret of dust adhering to materials, allowing the rocket to remain free of dust and rocks, while landing safely. In addition, it is possible to develop a device that propels small quantities of water to wet the dust and limit its effects.
Figure 6. Feasibility case for a dust cover on the Artemis surface.
4. Relationship between distance, weight, projection effects and landing time
In this subsection, we set up an empirical program to model the impact phenomenon on a surface covered with dust and rock :
We consider the variables :
Ø T, existence of atmospheric circulation
Ø U, the surface area of the impact zone
Ø V, rocket landing time.
Ø W, shock absorption time.
Ø X, rocket weight;
Ø Y, local gravity field;
Ø Z, kinetic force of the projected lunar rock fragment.
Based on this program, the following hypotheses can be formulated:
1. The surface area of the impact zone increases with the weight of the rocket.
2. The existence of atmospheric circulation contributes to a major risk during ascent.
3. Landing time contributes to rocket blast impact area.
4. Time to return to normal after landing depends on gravity and the existence of an atmosphere.
5. The weight of the rocket is positively correlated with the level of risk of danger from surface impact effects.
To minimize the risk of clouds of dust and rocky material forming during the ascent of Artemis, this would require simulations based on mathematical formulations that describe the relationships between the variables defined above. In addition, observations of each of these variables can be used to develop a simpler model with a study of multidimensional variation.
Conclusion
On the lunar surface, a rocket will weigh 6 times less than on Earth. Rock fragments and the formation of lunar dust clouds can be mitigated by studying the physical properties of the chemical particles that make up the lunar atmosphere. The disturbance of lunar surface materials during rocket ascent is due not only to the gravity field, but also to the atmosphere, whose density is almost negligible for the moon.
Landing with the least possible effect will require the invention of new prototypes incorporating artificial intelligence to maximize decision-making in the shortest possible time. Fuselage modifications and the integration of new rocket functionalities will also be required.

Remoras Full Chapter LXVI: Eye of the Tiger
If life were simple, I’d be a tadpole or a tortoise. I’d be a frog in no time, or I’d live to be over 150 and I would go at my own pace.
But life isn’t simple and action happens a lot. I have homework I have to do every week and if there was one thing about childhood which I wouldn’t recommend to a tadpole, it would be homework. However, that wasn’t my concern that day. My concern was something much more joyous: a sheet of paper in our mailbox.
See, we don’t get a lot of mail here, but we still have a mailbox, for whatever reason. Well, just this morning, I ran out (it stopped raining this morning, too. Thank goodness, no more soggy boots please) and caught the mail between my hands as if they were flies and my hand was a flyswatter.
I ran inside, as I was too strong to slip and fall down, and being reckless was impossible when I was built like a gorilla.
“Ray! Ray!” I jumped up while waving papers in my hands.
Ray, who I once referred to as “penguin man” (well all gotta grow up someday), was busy in the kitchen flipping eggplants.
“What is it, Tigershark?” He asked with his soft, but gravelly voice, and with a smile on his face.
“There’s a fair in town! An amusement park nearby! Can we go?”
“A..what now?”
I threw the sheet of paper in his face.
He muttered to himself while taking a look at it (in case you’re wondering, he set the spatula down before looking the paper over), saying stuff like, “how is it in town when we don’t live in a town? Why was this in our mailbox?”
“I don’t know! But it looks colorful!”
“It must be a trap…” he muttered.
“It might be, but we’re strong! I could bring my hammer with me, if you want!”
He shook his head.
“We’ll go. I’m curious about this. It’s suspicious, and I’m sure it was put in our mailbox to lure us in. Not only did Sunny not bring up such a thing with me when she looked up any recent rumors in the area, but this is so spontaneous that...ah, but let’s go, anyway? What do you say?”
“Yeah!” I jumped up and pumped my fist.
Sure, danger wasn’t always something I wanted to get into, but I had my values to stick to: value 1) have fun at all costs. Value 2) be there for the ones I love. The rest of my values weren’t important enough to mention right now.
As it turns out, Ray and I had to walk quite a ways in order to get to this supposed amusement park. Once there, we were surprised to find such a colorful area with so much red and yellow that one would have mistaken it for a sculpture made out of mangoes.
“This amusement park is called ‘Iceland’?” Ray remarked. “Doesn’t the owner realize that there’s already a place called Iceland? You can’t just put -land at the end of a word and call it the name of your amusement park.”
We were lucky enough that it was far enough into spring where much of the actual ice had melted off and the ground was soft, while the sky was bright and cloudy. Sure, a little on the brisk side, but I wouldn’t have had the cold any other way.
“Right! It should have been called something unique, like Humanland.”
“Oh, speaking of which, how are things going with you and Astraea?” Ray turned his head and asked. He stood in front of me in a long line, one which was single-file and all of these people were eerily quiet. I must say, they would have done a pretty good job at being mannequins.
“We’re getting along,” I answered. While my worries grew every week I was away from her, saying that we were getting along wasn’t a lie.
“That’s good. Is she learning anything new?”
“Every day, I’d assume,” I shrugged my shoulders. Sometimes her way of learning could be a bit...worrisome. Like how she wanted someone to beat her up ever since I threatened to beat up Hammond Cheese. Or how she wanted to explore her jealousy by creating a dragon because she thought it would make me come back home to grandma and grandpa.
I still regret nothing, but she could be quite the handful.
Besides, are we ever really apart if we can just communicate through our thoughts? I asked in my head.
Of course, Astraea didn’t give me a response. Either she heard me and ignored me or she didn’t hear it. Maybe it wasn’t a total telepathy thing. Like, maybe we had to have each other’s permission first, or maybe she had to call me first. I didn’t know how these things worked.
“That’s good. I’m sure you’re a good big sister,” Ray grinned. We walked a step closer to the entrance.
“I’m not sure about that, I’ve never been a big sister. Even though she knows less than me, I think Astraea is infinitely bigger than I am.”
“Well, infinity can only be so big,” Ray said, as if that meant anything. He really was someone who liked to say things that sounded like they meant things, but they didn’t really. Oh well, that’s part of what made Ray a good penguin.
When we stood before the entrance, almost through the gates, I turned around and looked up at some chubby blonde haired guy wearing a square hat and he had a nametag on it that said ‘Titus Bosom’.
“What brought you here, bub?” I asked.
“Oh hey, kid. I just got this thing in the mail saying I won a trip to Iceland. I got so excited until I found out that it’s not the country of Iceland, but just some amusement park. But I’m already here, so I figured I may as well check it out.”
“Right. So you’re just as in the dark as we are,” I nodded.
“In the dark?” His face turned pale (he was already a white guy before, but something told me that he wasn’t used to a cold place like this).
“Ah, forgive her,” Ray turned, “what she means is that amusement parks opening up here are certainly out of the norm.”
“Yes. Very suspicious,” I nodded, with my hand on my chin. “We will get to the bottom of this mystery and ride on some roller coasters.”
“Do we have to?” Ray groaned, “true, that’s a Sunny thing, but couldn’t we enjoy something more peaceful, like a haunted house?”
“No! Roller coasters!”
“Huh. Where are we, anyway?” Titus asked.
“Eh, it’s not quite Canada and it’s not quite Greenland, but it’s somewhere close to those places,” Ray answered.
“Of course. I just had to come to some remote area. Next thing I know, they’ll be harvesting my organs.”
“You play the organ?” I asked Titus.
“No, not the musical instrument...I did play the trombone once, but that was a dark period in my life.”
“Ah,” I nodded. The world of adults really was complicated.
Did you hear that, Astraea? Aren’t humans odd?
Again, no answer.
At least I wasn’t scared to admit that I missed her sometimes too. And I could do so without causing trouble.
We were at the entrance now. There was a booth and someone with long, brown hair which extended down to their ankles. They wore short shorts and a tank top and were shivering in place harder than even Remora did sometimes. On their face was a big, drooping, panicked expression.
“H-Hi, welcome to Iceland,” the chilly big hair greeted us, “here’s your ticket.”
They handed Ray and I a ticket. Ray took a glance at it, then pointed to the ticket.
“Shouldn’t we pay for this?” He asked.
“Here at Iceland, we don’t believe in charging money for things,” the booth person explained.
“What’s your name, stranger?” I asked.
“Oh. I’m…is this allowed? Um. I’m Calen? I’m kind of girl-adjacent. You could say that I’m not a girl or boy, but also I’m a girl. Mostly I’m scared because I don’t know why I applied for this job. And you are?”
“I’m Tigershark! I’m a tiger and a shark, but also I’m a girl!”
“I...I see. Well, this is, uh, this is...Iceland? Yeah, it is. Enjoy, please. My paycheck depends on it.”
“Sounds like a fragile paycheck.”
“Yes, well...it’s the only day Iceland will be around. So we gotta make the most of it, yes?”
“But why is it around today? Why not tomorrow? Why only today?”
“Ah...uh...I don’t really know, but I wanna get paid, you feel?”
I shook my head and scowled.
“Adults really are complicated,” I grumbled.
Once we were inside the amusement park, all the crowds around the area scattered to different areas of the park as if scared of Ray and I. Or maybe they were on a tight schedule. I really didn’t know.
“It seems like they’re all actors and we’re the audience,” Ray said.
“Or we’re the actors and they’re the audience?” I suggested.
“I think you’re right, but I also think it’s the opposite of what you said. I think they’re the audience who are also actors and we’re...Truman.”
“Truman?” I asked, sure it was just another Ray-ism.
“Right. I have to keep reminding myself that the 90s were a long time ago.”
We approached one of the rides, a spinny roller coaster with seats that looked like tomatoes.
“Let’s go on this one!” I pointed to Ray and tugged on his sleeve.
When we approached the ride, however, there was yellow tape in front of the gate saying ‘out of service’ and someone with long, brown hair which reached down to their ankles stood. I was so sure they were Calen, like the one at the front gate to the amusement park, but this person had a pink mustache on, so it couldn’t be Calen.
“Oh, uh, hello, uh, sir? Sorry, this ride...it’s closed,” they informed us, and I could’ve sworn they sounded just like Calen, too.
“That’s Ray,” I pointed to Ray.
“Oh, right, uh. Yes, you are. Ray, this ride is closed.”
“I’m Tigershark.”
“Yes, I remember you..er, I mean, nice to meet you. Sorry, this ride is closed.”
“You ARE Calen!” I pivoted my finger and pointed at them.
“I am! Err...am I? No, I am not! I’m...Caelid?”
“And why is the ride closed?” Ray asked.
“Because it is non-operational!” Calen (I was sure of it now) declared.
“Oh, so is it just for display? Is it a prop?”
“How did you – I mean, no. It’s just not working today.”
“What can we do here?”
“You can...play hackey sack? I like to do that.”
“Couldn’t we do that anywhere?”
“Eep! Maybe! You’re probably right! Well, there’s the haunted house.”
“Cool. Wanna do the haunted house, Tigershark?”
I crossed my arms and huffed.
“Fine, but I bet it’s not even haunted,” I pouted.
“I hope not! Haunted houses are scary!” Calen wailed.
“They’re supposed to be scary!”
“You’re right. You will have the scariest time of your life.”
Calen pointed toward the haunted house: it was just a small, long building of sorts with a fairly straightforward entrance and exit. As we headed toward, Ray took a quick glance ahead at the horizon, just a little past the back of the amusement park. Whatever he saw or thought he saw, he didn’t seem to want to tell me.
I’ll force him to tell me once we’re done with this haunted house, I decided.
There was no one waiting for us at the entrance asking us about tickets or anything. We just walked in. As soon as we did so, all the light from the outside world faded and we were left in a darkness that was quite befitting of the name ‘haunted house’. Of course, I could still see Ray beside me, with his hands in his jacket pockets.
Just a few steps in, a cardboard picture of a floating sheet ghost with big googly eyes popped out from the wall. Ray flinched, then flicked the cardboard picture. I turned my nose at such a fake scare.
Further in, we heard voices come from behind the walls:
“Ooh, I’m a ghost. Ooh,” moaned one of the voices in a rather uneasy, shaky tone. If I had to guess, I’d say that was Calen.
“I’m a zombie or whatever. I’m going to eat this ghost’s brain,” was the other voice, which sounded rather bored.
“No! Don’t eat my brain! Do ghosts even have brains?”
“Did you even have a brain when you were alive? Hmm? Or what about these people walking through the house? Perhaps they have brains. Yes. Let’s see if theirs are tasty.”
That time, I admit I let out a shudder.
Behind me, in what must have been just a few paces back, one of the walls slid open and I heard a creak. I dared not look behind me, even as the hair on the back of my neck stood on end.
Then, I heard slow, deliberate footsteps. Just a little light tap against the stony floor that we happened to walk upon.
As the footsteps drew closer, a low, rumbling groan sounded:
“Uhhh...flesh. Meat. Starch. Ketchup.”
Ray and I continued to walk at a steady pace but my legs were starting to shake real bad.
The zombie must have taken big strides as despite us keeping our pace, I soon felt a hot breath against my neck. Whoever’s breath it was, it smelled like buttery baked potatoes.
“AAAAAAAAAA!” I screamed and ran past Ray at top speed out of the haunted house.
As soon as I pushed through the wooden double doors, the outside world opened up and blinded my eyes and I bumped into some large, fuzzy figure right away.
Is it a bear? I wondered.
I looked up and there was Calen in a big bear costume, with her head poking out and little round bear ears at the top.
“Hello kid, I’m beary happy to meet you,” she tried working up a big, jolly bear voice.
“Sure you are, Calen,” I groaned and rubbed my head.
“Was it scary enough?” She looked back toward the door, which as soon as she said that, the doors opened and Ray walked out while adjusting his tie.
“I do say, that was a rather mediocre experience,” he remarked, “but what else should I expect from an amusement park? Especially one where there seems to only be two employees.”
“There’s more! Probably! I know I didn’t set this all up on my own!” Calen waved her bear paws about.
“Of that, I have no doubt. You and that zombie, or maybe there are more people, seem to only be pawns. But the purpose for this amusement park is the real mystery.”
“The amusement park is here for amusement! It’s in the name!” Calen jumped about.
“Right. Come along, Tigershark. I think I’ve solved this mystery.”
“Aye-aye!” I did a little salute, then hopped toward him as we walked away from Calen.
He had his sights set on a log cabin behind the amusement park, elevated on a small hill.
As we walked, he explained a few things to me.
“I’m pretty sure my hunch was correct: most of the fine folks we shared a line with were probably workers here, with maybe one or two people not in on the joke aside from us, to give off a veil of authenticity. But, of course, the con was so obvious that I have to assume we were meant to notice something suspicious about this place. I’m sure we’ll get the answers we need if we talk to the ‘boss’ of this whole operation.”
“I see,” my eyes widened and I nodded along. I didn’t understand all of it, but I appreciated some kind of explanation.
I still hate to admit it, but that zombie was scary, I thought while we walked toward the back of the park.
I noticed someone behind us, sneaking around. Sure, if it was a zombie, I would have beat them up, but no, it was a brown, fuzzy looking someone.
“What are you doing?” I turned around and saw Calen, crouched and following us.
“I...I’m making sure you two don’t go anywhere you’re not supposed to. I also work security here.”
“Do you now?” Ray asked.
“I’m also a clown,” Calen added, “I can do tricks to keep you two occupied. Or maybe you two want to ride on the carousel? I heard there’s horses. Though you may be disappointed to find that the horses aren’t real. I’m terribly sorry.”
“You’re a clown? Can you make balloon animals?”
Calen shook her head furiously.
“I’m a bear clown, bear clowns can’t do balloon animals. I can blow a balloon, but I just can’t shape it.”
“Some clown you are,” I said.
“Well, I’m not really a clown. I’m not really a bear, either. I’m actually a human. This is just a bear costume.”
“Sure, I’ve heard that one before, too.”
We continued our walk toward the building despite Calen urging us to go elsewhere. Before we could get too much further, a lone woman with short, white hair and wearing a blue uniform shirt with little chest pockets and sporting a pair of skinny jeans appeared.
“You will go no further,” she announced, blocking our way to the back gate. She then pulled out a pistol just to prove that she was serious and pointed it at us.
“You know too much. You need to be eliminated,” she said.
“You’re not going to shoot me, too, Cael?!” Calen cried.
“I don’t know,” Cael turned her attention toward Calen while maintaining her aim at Ray. “I always knew it would come to this, Calen: us two, on opposing ends of the battlefield. In the end, I have to decide whether my resolve is stronger than our bond.”
“Can we talk this out?” Ray asked.
“I would rather not. I’m not good with talking to people,” Cael replied. “The boss said that if anyone tries to snoop around, we should stop them. So that’s what I’m doing.”
“And who is your boss?”
“You know too much as it is! I cannot say any more!”
From Cael’s pants pocket, a phone rang and Cael picked it up.
“What?” She growled into the phone.
“Put the gun down. There’s been a change of plans. These people are our guests, after all,” I heard the ‘boss’ tell Cael.
“Do you know how inconvenient this is for me?!” She shouted.
The boss hung up and Cael put her phone back into her pocket, then tossed the gun aside.
“It wasn’t even a real gun, anyway,” she grumbled, then walked off.
All three of us watched Cael walk away to the side, past where the haunted house attraction was.
“Where is she going?” Ray asked Calen.
“Oh, Cael always goes to fast food restaurants and orders a bunch of french fries whenever she gets mad. The boss set up a Burger Duke in the amusement park, with actual employees, just for Cael,” Calen explained.
“Oh! Are you and Cael a co…?” I was about to ask when Calen interrupted.
“Yeah, we’re a coworkers. Been coworkers for years. Always applied to the same jobs, always on the verge of homelessness.”
“That’s impressive!”
“Is it? It’s scary never knowing where our next paycheck or meal or shelter is going to come from. Plus Cael can get pretty scary, especially when she doesn’t get her fries.”
“Adult life does sound scary,” I nodded.
“I know, right?! I just want to be a teddy bear!” Calen whined.
“Hey, let’s meet up with your friend Cael at this place,” Ray suggested, “besides, I’m sure Tigershark here is hungry.”
“We’re not friends, we’re a co...coworkers!”
“Roar!” I said to show that I was hungry. My stomach growled in agreement.
All three of us headed toward Burger Duke. It was a popular fast food restaurant chain. Grandma and Grandpa took Astraea and I there a few weeks ago. Astraea got a mini-whooper, while I got a double whooper with extra pickles. The food was...fine. It was tasty, but I knew in my heart that I could cook better food than that.
Astraea still found it an interesting experience, and even tried dipping her fries in multiple sauces at once. She even tried mixing several sauces together. I’m talking honey mustard, ranch dressing, barbecue sauce, ketchup, and mayonnaise.
Grandma and Grandpa were happy enough seeing her seem to enjoy herself. I enjoyed it too, because it was yummy food. But again, I could have cooked better.
As soon as Ray, Calen, and I walked into the Burger Duke, we looked around and saw Cael sitting at one of the booths with a tray covered in fries. It looked like fry mountain over there. She ate one fry at a time, and in between every few fries, she sprinkled a ton of salt over the fry mountain.
I ran toward Cael while Ray stepped up to the counter to order food.
“Hey Tigershark, what do you want to eat?” He called over.
“Salmon nuggets!” I cupped my hands and shouted back to him. After he nodded, I walked up to where Cael was sitting.
“Can I sit next to you?” I asked.
She shrugged her shoulders and said, “sure.”
I crawled upon the booth and sat next to her.
“Can I have some of your fries?” I asked.
“Sure.”
I took a handful and shoved some in my mouth. Calen walked up to Cael too.
“H-Hey Cael, are you mad?” She asked her coworker.
“Not anymore. I have fries now,” Cael answered. “Want one?”
“Yes please! I haven’t eaten all day!”
“Who’s fault is that?”
“Mine,” Calen pouted.
“Yes. I always tell you to eat plenty of starch,” Cael shook her head, grabbed a fry, then held it up to Calen’s mouth. Calen opened her mouth and leaned in closer to take the fry out of Cael’s hand.
I’m pretty sure Calen swallowed that fry without chewing as it was gone in one gulp.
“Good as always. Tastes just like you, Cael,” Calen remarked.
“Hmm...not a bad thing to taste like.”
Ray sat down and brought over a box of salmon nuggets for me. He also had two sodas in his hand. One, a prune soda, for him, and for me, a tangerine soda.
“Ms. Cael, I’m sure you think I know too much, but I can assure you that I don’t know enough,” Ray said to Cael.
“Just Cael is fine. And you know what you know and you don’t know what you don’t know.”
“That is usually how it works, yes.”
“I want you to know that even if it looks like I take my job very seriously, I actually just want to eat and have a roof over my head,” Cael explained.
“That’s something everyone should have, yes,” Ray agreed, “I certainly wouldn’t want to take food or a roof away from you. I just want to know: who is your boss?”
“I don’t know his name, he just wanted us to call him boss. He looked kinda like you, actually.”
“Really? I thought he had brown hair,” Calen added.
“Maybe his roots were brown, but I’m pretty sure his hair itself was black,” Cael argued.
“Would you mind if I went to see this boss of yours?” Ray asked.
“I don’t mind. I’m off the clock right now.”
“You are? I didn’t even know we were ever on the clock,” Calen replied.
“But of course we’ve been on the clock. If we weren’t, we wouldn’t get paid, right?”
“No, no, because the boss already paid us for a day’s worth of pay before we started our shift today, right?”
“Huh. I’m going to have to ask him about that. Maybe I should go with you.”
“Yes. Let’s all four of us get down to the bottom of this mystery,” Ray agreed.
“Mystery solving time!” I cheered.
I shoveled the salmon nuggets into my mouth and chugged down the soda. Calen and Cael shoved handfuls of fries into each other’s mouths. Ray took his time.
It didn’t matter, because we were soon out the door anyway and headed toward the back of the amusement park.
Up the hill, we reached the cabin. Ray knocked on the door. Then I knocked harder and faster. There wasn’t an answer either time.
“I’m pretty sure it’s unlocked,” Cael said before turning the handle on the door.
Indeed, it was unlocked, and we soon walked in.
The carpeted floor had some kind of confetti pattern along the way, while the walls were a fresh pine scent of wooden boards. We passed by a lot of doors before we reached one where a sign said ‘boss’s office’.
Ray knocked. Still no answer. However, this time, he was the one to open the door, and not Cael.
All four of us walked in, only to find the office without any boss in it.
There were bookshelves on each end, a window with a view to the outside, a big desk, and a puffy leather swivel chair. No boss, though.
“Were we scammed again?” Calen asked.
“We already got paid, didn’t we? Isn’t that good enough?” Cael replied.
On the desk sat one of those phones which had a squiggly wire attached at the bottom and hooked up to some machine.
As soon as I noticed it, the phone rang.
Ray picked it up, and it went right to speaker phone as we all heard:
“Hello, Ray. I hope you were as amused by this amusement park as I was. I’m sorry we couldn’t meet today, of all days, but don’t worry, you will be seeing me around real soon,” the mysterious boss said.
“Aion? Why did you go through all this trouble?” Ray asked.
“Eh, eh, eh. No, Ray. Not yet. We can talk more once we meet. For now, I’m happy enough just to know that you heard my voice. Or maybe I’m happy to hear your voice. I’ll let you decide.”
Ray didn’t give a reply, and I thought the call ended, but then the voice had one more thing to say:
“Oh, by the way, Calen, Cael: you’re fired.”
The two girls next to me both erupted into a panic and held each other tight.
“Why?!” They cried.
“Because the amusement park was one day only. Now that I have no use for you two, there’s no reason to keep you around.”
“Wait, Aion –” Ray tried to get another word in, but was interrupted.
“No, I’m not taking any questions at the time. See you around, Ray.”
The call ended.
We all took turns staring at each other, not sure what to do now. In fact, the first person to talk was Calen, who said exactly that:
“We’re all just staring at each other, but I’m not sure what to do now.”
“We’ll have to look for another job,” Cael answered.
“But out here? And in the middle of nowhere?”
“We’ve been through worse. I’m sure we’ll find another job together.”
“Right. You wouldn’t leave me.”
“Unless I find a job that hires me and doesn’t hire you, then I might.”
“No!” Calen sank to the floor and hugged Cael’s knees. “Say it isn’t so!”
“You two. How about you come live with us at our diner?” Ray suggested.
My mouth widened into a grin. As odd as those two have been, I really did enjoy their company.
“We’re really going to add more people to our home?” I asked, the excitement leaking from me.
“Sure. We’ve got rooms available, if they’re willing.”
“But we can’t just live there without working, can we?” Calen asked.
“You can wash dishes, if you want.
“Will there be french fries?” Cael asked.
“We have potatoes. It all depends on whether we decide to deep fry them.”
“We’re in,” Calen and Cael agreed.
And so, the four of us took our journey back home to the Remora’s Full Inn.
