How gravity assists work. Voyager 1 used gravity assists to accelerate to about 17 kilometers per second, but how do gravity assists work? In this video, I will be explaining the orbital mechanics behind a gravity assist without going into math or fancy terminology. Even your dog will be able to understand gravity assists after watching this video!

This is just a small preview of my upcoming video on how rocket engines work. Rocket engines might sound complicated, after all, it's rocket science, but it's not! At the end of that video, you will know how SpaceX's Merlin engine works, which is used on SpaceX's Falcon 9 rocket.

Let's talk about why rockets smoke before launch. We've all probably watched a SpaceX Falcon 9 launch before and asked ourselves: what is the white smoke before a rocket launch?
To understand the source and reason, you will get the SpaceX Falcon 9 explained by me. Not the entire thing, obviously, but everything needed to understand the white smoke. Additionally, we'll have to deduct a quick rocket fuel comparison because to understand what causes the white smoke before launch, we'll have to dive into cryogenic rocket fuels.
All of this may sound complicated, but trust me, you don't have to be Elon Musk or a NASA rocket scientist to understand this stuff. And as a bonus, after this video, you will know a little more about how rockets work. Sounds pretty cool, right?
What started this journey for me is that I asked myself: "Why do rockets smoke before launch but stop smoking once launched?" That was super weird for me, but after looking at some schematics of SpaceX's Falcon 9 and learning about cryogenic fuels, I finally know why rockets smoke before launch! I can even explain it in under 60 seconds without leaving out any important details. That's how confident I am in my ability as a hobby rocket scientist!
So let's dive into it and finally solve the mystery of what the smoke before most rocket launches is!

Starship orbital refueling explained. Once Super Heavy has carried Starship into orbit around Earth, Starship will be empty. So if SpaceX wants to then send Starship to the Moon or Mars, it has to be refueled in orbit. For that SpaceX, will send dozens of Starship tanker variants to refuel the empty Starship in orbit. But how will that exactly work? How does orbital refueling work?

How we will find alien life using the James Webb Space Telescope.
Some people may consider Scott Manley or Tim Dodd, the Everyday Astronaut, to be alien life found on Earth because of their huge knowledge about space, NASA, and MrBeast challenges. But trust me, what seems like extraterrestrial life, is often just SpaceX's Elon Musk playing Kerbal Space Program, crashing some Starships, or Joe Rogan on DMT eating Elk meat. Finding extraterrestrial life in real life takes something like the James Webb Space Telescope induced with Minecraft steroids. Smart astronomers like pewdiepie have developed techniques to analyze a planet in great detail even though being light-years away from Earth. This may sound like something only Neil deGrasse Tyson and Bill Nye themselves can understand, but don't worry, I, the NFT astronomer and Spiderman scientist, will explain how we will find alien life in under 1 minute, in a scientific manner!

SpaceX's Raptor engine is ridiculous in itself, but the raptor's turbopumps are even more ridiculous. SpaceX's Starship and Super Heavy are huge and require powerful engines to launch into space. For that, SpaceX has developed the Raptor rocket engine, but what makes a rocket engine so powerful?
In rocket science, rocket engines are sometimes referred to as flying turbopumps because the thrust depends on how much propellant you can shove through them. And for that, rocket engines use extremely powerful pumps that are driven by a gas turbine, hence the name turbopump.
SpaceX's Raptor engine has two turbopumps. One for the liquid methane and one for the liquid oxygen because that's the propellant that Starship and Super Heavy are going to use, and, let me tell you, those turbopumps are extremely powerful! In this video, I will show you how powerful they truly are!

Aerospike engines explained. Aerospike rocket engines solve one fundamental problem that traditional rocket engines using a bell nozzle have, and that's great, but how do aerospike engines work? I will explain the fundamental principle behind aerospikes and dive deep into their combustion cycle. Additionally, I will talk about the aerospike's problems that traditional rocket engines don't have!

How ion engines work. Ion propulsion, meaning ion thrusters, are used in almost all satellites and space probes. One example is NASA's evolutionary xenon thruster, or short NEXT, which is used on an asteroid-slamming mission for its ridiculous efficiency, but how do ion engines work?
Ion propulsion engines might seem complicated, using unconventional methods compared to rocket engines like the Raptor, and even though those ion engines are considered to be electric propulsion engines, they are not 100% electric. So it's a little bit confusing.
You still need a gas to ionize, but to ionize said gas, you need electricity, and to then accelerate it, you also need electricity.
So even though gas is involved, the most important systems of an ion propulsion engine are electric, explaining why it's called an electric propulsion system.
But enough talking and lazy inclusion of keywords. Let me explain ion propulsion to you using a fancy ion engine animation that I did.
And trust me, even people like MrBeast and pewdiepie, who have no clue about rocket science, could understand how ion thrusters work after this short 60-second video!

Centrifuges in space could provide artificial gravity for the astronauts living there. Not only in space stations but also in spaceships going to Mars and beyond. However, those astronauts would experience some weird things. Why? Let's explore this question in this video!
