Why Rockets Smoke Before Launch - Rocket Science in 60 Seconds

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!

Dang, this is really high quality content. I’m surprised you don’t have a million subs.

[Berilaco]

The way i can already tell that you are german after just 5 seconds is amazing xD

[uk]

I looked up that exact question and this was the perfect answer

[berenedain]

The rockets smoke to calm their nerves, their odds aren't good.

[PigtasticShorts]

Amazing I hope that you post more content like this!

[vishveshmishra]

Amazing work !!! You are awesome bro !

[shahidahmed]

love ur explanation.. it's cool truly

[SebRusso]

I thought it was mainly just because of the fact that they just get extremely hot in general. I wonder if theres any way to cool down the evaporating oxygen at the top so it turns back into a liquid.

[Astroponicist]

I might be beneficial to have a non contact inlet near the overpressure vent. the inlet would lead to the gas fractionator for oxygen production. the somewhat higher oxygen content at that location could lead to a higher efficiency in the production of oxygen.

[satyamjayashawal]

But this will affect the required quantity of oxygen for the combustion?...is it already considered in the weight

[ArcaneShadowEssence]

wait a minute..
are you the guy from Egosoft?
i usually listen to x4 foundations podcast and your voice sound very much like his

[xdragonk]

But the O2 gas is still in the air too, right? Are those flammable still?

[normalwaffle]

Might be a stupid question, but does the same apply to cryogenic fuels like hydrogen and methane?

[dennisssmock]

Look if you're about to do what they're going to do. You're gonna want to smoke one before you get it going.

[RichardSpeights]

Hummmm. Gotta watch out for the water wapor.

[alberthagi]

Keep the great work up keep educating the world. Also please consider joining the Planetary Society you would make an amazing addition and you get great information straight from bill nye!

[berrybee]

Cryogenic means does it contains cryolite ??

[gamercube]

Wouldn't that waste a lot of oxidizer????

[abyay]

Then fuel will be decreasing then how actually it works
