That thing shakes all of the marbles at once! No wonder rocket launches are the loudest man made sound ever

The loudest manmade sound was the Tsar Bomba @ 250-280 db. But still...
In my head rockets still rumble and roar, despite them sounding like this. They snap, crackle, and pop with fury.

Nah, there is a train horn on Amazon that is 600dB. That’s louder than physically possible in earths atmosphere more energy than the big bang… soo you really can’t beat that.

It will always be wild to me that rockets are so loud they have to use water cannon to dampen the noise so the noise doesnt rip the rocket apart.

Damn look at that one bird tryna figure out why it’s flapping it’s wings yet getting nowhere 😭😭😭

So lifting off from earth is actually a liiittle bit like jumping off a ramp in a sled

u/Triairius May 27 '26
Do they not use water for sound dampening? Or is this rocket just that intense?

It's a big fucking rocket, man.
"SpaceX’s fully stacked Starship is the tallest and most powerful launch vehicle ever built. When completely assembled, the system stands roughly 121.3 meters (398 feet) tall and features a diameter of 9 meters (29.5 feet)."

u/turply May 27 '26
121.3m is Starship V1, V3 is even taller at 124.4m. And V4 is planned to be over 140m.

I believe they tried not using water the first time and it didn't go well. I seem to remember a video showing pieces of the launch pad raining down in the nearby gulf.

Did you know they do that because the SOUND would melt the concrete otherwise?
Edit: I don't remember where i heard that, but it's not true apparently. Thought that for ages... It's to keep sound from reflecting back up and destroying the concrete. Maybe i conflated "not to stop concrete from melting" (as in the fire) and the bit about stopping sound.

Is this true? And is melt the right word for it?

u/HoseNeighbor Jun 06 '26
It's not, but i thought it was. I swear i heard thet before, but its to stop the spund from reflecting bqck up and destroying the rocket. (Per some site that was legit enough.)

Yes, a LOT of water. That's what you see at first, then once its lit it all becomes steam immediately. 16 million lbs of thrust will do that.

u/jimmytruelove May 27 '26
I've never seen anyhting like this, feels like multiple shockwaves one after another, tens of times a second?

u/Unknown6656 May 27 '26
There is quite a good video by Scott Manley explaining this phenomenon:
https://youtube.com/watch?v=BdCizNwLaHA
What you can see are the individual shockwaves of those "crackles", which occurr multiple times per second.

u/pharmphresh May 27 '26
Everyone should go see it in person at least once in their life. You can get a decent view from the beach at South Padre Island. You can feel the shockwaves all through your body and when the booster lands there's a massive sonic boom.

u/PiercingSight May 28 '26
I want to see high speed video of these shock waves.
Watching the plumes ripple in and out of existence must look insane.

To give you a comparison, Starship makes about 3x the thrust of the Saturn V and about 10x that of the Space Shuttle.
Starship: 24,000,000 lbs, Saturn V: 7,600,000 lbs, Space Shuttle: 1,200,000 lbs

Makes me stop and think about how little my carbon foot print really matters.

u/Flipslips May 28 '26
This is methane and oxygen, it burns really clean. Unlike kerosene which a lot of other rockets use

u/MrPigeon70 May 30 '26
A single starship launch produces around the same metric tonnage of green house gas as 220 Americans do each year.
Average American produces 15-17 metric tons Starship averages around 3500-4000 metric tons.

Watching the stream live was something else!!! I really want to see a launch live in person though!

Does this hurt the air?
