hello! out of curiosity, do you have any headcanons/theories/etc. concerning how moonlight mansion’s secret laboratory area factors into the dmk connection? if you don’t mind my asking, i’d love to hear your thoughts if you have any :>

Not...yet. Not a full one, anyway. I will say that the secret lab was in the back of my mind as I was writing my initial post.

Was tempted to say it belongs to someone else. King Dedede is always portrayed to be a secret gear-head but the tubes...

(Photos for those unaware of Moonlight Mansion's secret underground lab)

If... If Dark Meta Knight never had his own "Dark Halberd" and Moonlight Mansion was only his home base... Well, the Halberd is run on Wheelie technology (like the lab has Sparkies) and has similar trap/breakaway passages on it like the basement does...

Although if DMK didn't have his own Revenge of Meta Knight-style coup on Dream Land in the wings... what the HECK was he planning on doing with THIS stuff??! (All of a sudden, the idea of Susie and DMK bonding doesn't seem that strange after all...)

I've also thought a lot about DMK choosing Radish Ruins for the site of his second ambush. If it's a sign that he's got a barely concealed interest in ancient technology and old cultures as MK does...

(I was also thinking about how Moonlight Mansion is a hub to just two realms: Onion Ocean and Candy Constellation. Onion Ocean could relate to the sunken Halberd but I don't have anything relevant for Candy Constellation. It is one of the more tech-y of the realms so that could be where he got the equipment at least...)

If the Mirror enhances the negative, perhaps... MK's interest in the past was taken a bit too far in DMK? Perhaps he wasn't just content to observe it, he wanted to try and reproduce some of it?

...Then again, we're also talking about the guy who, when given a crayon and told he could draw whatever he wanted chose SWORD.

(I tease. Though him drawing a sword badly is still the funniest thing ever)

And, you know, perhaps he just needs a lab to keep the Halberd up and running? This baby is not gonna maintain itself!

Although, hot damn, that test tube is full of GREEN liquid isn't it...?

:Dess begins shaking violently:

EDIT: Last minute thoughts!! If he's got portraits of the realm bosses up, maybe he was...running experiments to try and connect the realms?? Or power the cellphone batteries...??!?

(Who DOES make those batteries? Maybe it IS DMK?!)

Science fact of the day- Liquid rocket engines!

Because solid rockets are not quite effiecent enough and lack control, other types of engines are very needed. Liquid engines make up the other type of chemical rocket, although these two come in two main types.

Pressure Fed engines are the simpler type of engine. these engines will have their fuel tank, and then behind that, there will be a large tank filled with pressurized gas of some kind. whenever they need to burn the engine, they open valves and the pressure pushes the fuel down into the engine so that it can burn inside the combustion chamber. There are a few major advantages to pressure fed engines: for one, theyre incredibly reliable. with other engine types like we'll see later, there's a lot more systems that all have to work better for the engine to work, and if just one fails, your engine could be done, or even worse, your whole rocket could explode. with a pressure fed engine, theyre far more likely to just work when you turn them on, every single time. Which is another advantage- they can be used over and over and over again as long as you have fuel. they're great for missions that will need to do multiple smaller burns, such as those exploring other planets. Cassini, for example, fired its two engines a combined 200 ish times or so in order to line in up to have the best orbit for studying different things about Saturn as well as lining up orbital encounters. Only a pressure fed engine can have that sort of reliability. however, they have a major downside: theyre not super effecient- in fact, theyre often similar to solid rocket motors, in that 2 ish km/s range. still, for the reliability they provide theyre still often the best option.

I should also mention cold gas thrusters- theyre basically this taken to the extreme. they cut out the middle man by just straight up pushing out pressurized gas instead of pushing fuel into a combustion chamber. they're incredibly simple, they're incredibly reliable, and they're like, way less effecient. they do still have a good use, and that's attitude control. if you look at a picture of the space shuttle, you see all these little holes in the front and some itty bitty thrusters on the back- it's a large number of cold gas thrusters that can be used to rotate the spacecraft in literally any way they need. because cold gas thrusters are really really simply and reliable, this makes them the best suited to this tast, which requires precision in firing the engines and reliability to opperate them literally hundreds of times, maybe even within a single mission. these kinds of systems are called Reaction Control Systems (at least it was on the space shuttle) and that's basically the only niche these guys fill but theyre still pretty neat

finally, we have pump fed rockets. these are the real big boys, your F-1s and your RS-25s and your Merlins and your Raptors. The defining aspect here is a turbopump- basically its a pump built to spin at insanely fast speeds (on the RS-25, it was THIRTY THOUSAND rpm), and with high torque too, because they need to to move this much fuel, and again using the RS-25s as an example, it was something like 800 kilos per second for each individual engine, although the F-1 engine burned like 2500 kilos per second per engine, which is like an entire car's weight of fuel in a single second flowing through those pumps. so this raises the question? how the fuck do you power a pump that powerful? well, we have a bunch of rocket fuel lying around, so why not use just a little bit of that? only a very small amount of fuel is actually burned in the turbopump, so its a fairly small price to play for being able to achieve the absurdly high thrusts of rockets. Now, the engines i've talked about here are probably doing more than the average rocket engine, most probably have rpms in the 1-10 thousand range, and handle far less propellant per second, but i like going to the extremes to show the kinda shit these engines do.

You can probably see why these engines are so complicated. However, the benefits are easily worth it. They're the only way you can come even close to the power of solid rocket boosters, and they have the added bonuses of being more efficiency, while also being controllable. while many of them are made to only fire one time, they can usually be gimbled (pointed a little bit to steer the rocket) while executing their burn, and some of them can be operated multiple times in one flight, or at least be refurbished between flights (such as the RS-25). so how do they do on efficiency compared to the other engines? well it actually depends massively on their fuel- which i'll talk about tomorrow so byeeeeee

UC Riverside chemical engineers have designed a fuel that ignites only with the application of electric current. Since it doesn't react to flames and cannot start accidental fires during storage or transport, it is a "safe" liquid fuel. "The fuel we're normally using is not very safe. It evaporates and could ignite, and it's difficult to stop that," said Yujie Wang, UCR chemical engineering doctoral student and co-author of a new paper about the fuel. "It is much easier to control the flammability of our fuel and stop it from burning when we remove voltage." The Journal of the American Chemical Society paper describes how the team created the fuel, and additional technical details are also included in the patent they filed. When fuel combusts, it is not the liquid itself that burns. Instead, it is the volatile fuel molecules hovering above the liquid that ignite on contact with oxygen and flame. Removing an oxygen source will extinguish the flame, but this is difficult to do outside of an engine.

sorry for being so angry tonight. a better world is possible, we have the engineers, the knowledge, and the power to do it. but our world is driven by a greed and hatred unlike any other, one that sucks the soul out of us all.

we can live lives filled with peace, love, and relative comfort but it's been decided for us that we can't. we can uncover the secrets of our world and universe, but we only chose to do so when it's profitable.

there are so many amazing, wonderful, beautiful people on this world. so many vibrant cultures, so much love, so many hopes and dreams. but the west takes it all. capitalism takes more than the world can provide, pushes people into poverty and slavery, all so only a few can play with us all as mere toys and have dick waving competitions.

we're turned against each other, we're told others are savage and inhuman, that they're just a number, just a percentage point. they play god, and as one that is filled with nothing but vengeance and rage. one that only seeks to punish and hoard all that there is, until there isn't anything else anymore. we could've made such a beautiful world for ourselves by this point if a few key things had gone through, but greed and hatred was won time and time again.

my only hope is that we can finally start to push this horrid system into the fire, and we can truly start to set things right. for all its failings, i think the internet has really started to bring us together. i just want people to live and be happy. i want everyone to be able to follow their dreams and feel love. i really hope we can reach that point someday.

Robert Goddard Day

Robert Goddard Day is celebrated on March 16 every year. It is a day to celebrate the great mind of Dr. Robert Hutchings Goddard and his achievements. He is known as the father of American rocketry and the space age. Dr. Goddard discovered the technology and created the first liquid-fueled rocket in 1926. The success of his test is considered a milestone in the space age. His achievement is of the same importance as the invention of the Wright brothers in testing the first flight. He conducted the test from Auburn, Massachusetts, earning him the title “the father of modern rocket propulsion.”

History of Robert Goddard Day

Flight is a dream for every human being. Birds have always made us jealous with their ability to soar through the freedom of the vast white expanse of the sky, watching the flightless beings on the ground. On December 17, 1903, the Wright brothers took to the sky, giving wings to the dreams of humans to touch the sky. What felt like an impossible event a few decades ago is now easy to achieve. With the sky conquered, the next dream is to reach the infinite distances of space. The problem with the airplane is that it depends on the air and air pressure. Space does not have air, and, thus flight is not possible.

Dr. Robert Hutchings Goddard was born on October 5, 1882, in Worcester, Massachusetts. He had a way to work in a vacuum. He predicted that a rocket would be able to work in the emptiness of space as it does not need air to push. He was a physics teacher at Clark University in Worcester. He had already started working on his idea of space travel in 1915. When Goddard claimed that the rockets could be used to transport payloads to the moon, he was ridiculed, and his theory was considered folly. But time taught them they were wrong.

Goddard did not live long enough to see his childhood dream of space travel realized. But his work laid the foundation for propelling modern space dreams.

Why is it important to have rockets?

They help deliver satellites to space and enable global communication, weather forecasts, and other technologies like GPS, which are an integral part of our lives.

How did rockets change the world?

Rockets changed warfare. Due to intercontinental ballistic missiles and nuclear warheads, wars are no longer possible between major powers due to mutually assured destruction. Rockets also opened a frontier for space exploration. It helped revolutionize the technologies that we are so dependent on.

How to Observe Robert Goddard Day

Carry out a science experiment: This day is best spent doing a science experiment. You can start small with an experiment like collecting gas from a soda bottle. Record the experiment and post it on social media.

Watch a scientific documentary: Another easy way to spend the day is by watching scientific documentaries. Fluidity, air pressure, gravity, space, chemistry, etc. You choose the topic and start watching.

Create a mini rocket: You can purchase small rockets that can be assembled and taken off. Don’t worry, if they are not as advanced as the original rockets. We do not have to be rocket scientists to work on them.

5 Interesting Facts About Rockets

Arrows and rockets: The first rockets were used to propel arrows with greater speed and impact.

The first rockets: The Song dynasty of China found ways to weaponize gunpowder-powered rockets during the tenth century.

The ‘Father of Rockets’: It took Goddard 17 years to develop the first liquid-fueled rockets.

The iron-cased rockets: Tipu Sultan of India used iron-cased rockets for military use.

The first space rocket: In 1957, Russia created Sputnik, the first rocket that reached space.

Why Robert Goddard Day is Important

Space is infinite: Space is infinite. The contributions of Dr. Goddard helped us reach the infinity of space.

Sky is no longer the limit: Something beyond the sky just opened up thanks to the rockets. Now we can dream even bigger into the vast dark space.

It promotes innovations: Innovations can change society. With the advancement in technology, advancement in human civilization follows. The rocket's innovation now allows us to launch satellites and progress into the modern world.

the original manga is my favorite astro boy setting mostly because i feel it has the strongest connection to the influences and ideologies and perspective that caused the idea in the first place but also pretty significantly because i like thinking about how atom just had an active nuclear engine running inside his body at all times and thats just something the people around him had to deal with
