Rocket science. A term we all use to describe something incredibly difficult. Trying to grasp all of the concepts involved in rocket science can be incredibly intimidating.
My name’s Tim Dodd but I'm better known as the Everyday Astronaut. Recently I fell head over heels in love with spaceflight. My appreciation and curiosity for the subject grew into an obsession. Before you knew it, all I wanted to do was learn more and more... the more I learned, the more I wanted to share what was making me so excited.
But as someone who dropped out of college and has no technical background or degree… I really felt unqualified for the job of explaining rocket science to anyone. But the fact of the matter is, if I can learn this stuff, anyone can.
Rocket science is awesome, and you don’t need to be a rocket scientist to be excited.
Everyday Astronaut. Bringing space down to Earth for everyday people.

Improvements we made... Elon is not a scientist he only knows what the scientist tells him.Vor 11 Stunden
HEY TIM! Gotta ask WTF is that puff of gas at ~8:12 in this vid (from Rotor Visual's segment). Looks like it originates at the intersection of the booster and Starship then is visible as a puff of cloud a couple of seconds later as the stack continues upward.Vor 11 Stunden
Why dnt you launch from mt kenya?Vor 11 Stunden
That's why listening is very important unlike "India entrepreneur" who thinks they are GOD.Vor 12 Stunden
Great comparison. So now, what about fuel efficiency? Consuder that the Apollo rockets went to the moon and back with only one fueling. Starship, on the other hand, currently is going to take several refuelings. What's the difference? How much fuel is going out the nozzle of the booster? How do you find out? How might that be improved so that it too can go to the moon and back on one fueling?Vor 12 Stunden
SpaceX did, at least, prove that the concrete wasn't what the concrete company sold them on.Vor 12 Stunden
Blue origin can't spell orbital velocity.....😂Vor 14 Stunden
Well they already beat the Soviets so becoming another N1 is not a concern, looking forward to the 3rd test, if they get this thing to orbit and back safely, it'll be just jawdropping, China has beaten them to the first Methane powered rocket to reach Orbit but their rockets are nowhere near as powerful as thisVor 15 Stunden
Dude-man just let a rando ask a good question. Immediately, he realizes he missed something obvious. No hemming and hawing, just 100 percent focus on improvement without posturing. For most people, ego would prevent that level of engagement with a random from happening in the first place.Vor 16 Stunden
It wont be published in the USA. Enol's Snake Oil Manual may be published somewhere else but you still gonna have to buy it buddy.Vor 20 Stunden
Six engines good, twelve engines BAD!Vor 21 Stunde
The funny thing to me is the Artemis astronauts will be crammed into the sardine can Orion to get to the moon.. then transfer over to the luxurious in comparison Starship to land.. where they can stretch their legs and hop around or grab a martini from the space fridge.. then they gotta squeeze into orion again to leave.. they are not gonna want to leave starship 😂Vor 23 Stunden
Elon is our generation’s EinsteinVor 23 Stunden
Why? Does the atmosphere pressure interfere with a larger ratio and thrust is actually lost instead of gained from the larger chamber?Vor Tag
Thanks for your fantastic work/knowledge…can you make a topic for gimbal mechanism on rocket engines, thanksVor Tag
Maybe you should make a video of how anti slosh techniques workVor Tag
Was it really such a great question? It was just a yes or no question, not even an open-ended one. Answering yes just made Elon RE-THINK about WHY. The why isn’t what the questioner asked, it’s what Elon asked himself. It’s good to have ppl around who will question even the greatest minds. God bless 🦋Vor Tag
I used to get chills watching this, but ever since Musk has revealed his true persona it really took the luster off what he has achieved. The sooner he goes to Mars, the better off humanity will be.Vor Tag
Musk did not build this rocketVor 16 Stunden
What personaVor 17 Stunden
This is why I love Elan Musk .Vor Tag
Such a shame N1 failed. It would make the space race even more interesting...Beyond anything, N1 was a beauty. The most beautiful rocket ever built. It almost looked like a Gothic cathedral...Lucky those who saw it lifting up from the pad.Vor Tag
Not the bubbles are chipping away (it sounds like a bubble floats by, hits the blade and the blade is damaged), it’s the *collapsing* of the bubbles, a bunch of mini implosions. You have the same with ships and submarines. Especially submarines are trying to avoid it, because the collapsing bubbles generate so much noise.Vor Tag
What I respect is how he didn't allow his ego to stop him from admitting that he had made an oversight and even said thanks to the guy instead of rejecting his input in the fear of looking bad himself which I feel a lot people in his position would do.Vor Tag
Slick six what, where's that launching site located,?Vor Tag
this video is beautiful ! it looks like ethereal SciFiVor Tag
Watching his brain work is awsome. GreT inspirational momentVor Tag

Those rocks the engine is kicking up I’ll bet are flying fast enough to kill youVor Tag
merlin had 70 flight's 4 years ago? today it's like 280 flights and over 250 landings 😮. also proved 18 reflights on one boosterVor Tag
Elons hairplugs look do natural.Vor Tag
The starships Raptor engines are so simply constructed, that this is not the problem and we all know it. SpaceX will succeed.Vor Tag
this is why you never surround yourself with yes men.Vor Tag
I'm not a fan of Elon Musk. That does not mean I do not hope for SpaceX to be successful. There are a lot of people not named Elon Musk who are dedicated to the project. It's employees deserve the success. I do hope though that Starship does not end up being another Cybertruck or Electric Longhaul Truck. Elon keeps moving the goalposts and hiding the true capabilities of their product. Human Robot can sort blocks with one hand and when finally let out of its harness could do a slow shuffle forward. Meanwhile, Boston Dynamics has robots running, jumping, flipping, and able to perform tasks. The Electric Longhaul is questionable on being able to haul .25-.5 the haul of diesel trucks. Distance and time to recharge are also questionable. I would love an all-electric long-haul that could surpass diesel vehicles. But right now it is more Elon hype than reality. This seems to be Elon's issue. Much of it is just hype. He is portrayed as a genius, but that is questionable as well. He did not design the Tesla, he took the company from his copartner who designed it. He did not even found it as many claim, he is just the face of it after he used the money he made from PayPal to buy into Tesla. Elon is a snake oil salesman who takes advantage of other people's engineering. He is not some business or engineering genius. We can see this from what he did to Twitter. All this being said. This video said that the N-1's four attempts never made it past the first stage. I would like to point out that Starship's second attempt had a successful hot-burn separation. Granted a success for SpaceX is far different than what was expected from the N-1. The N-1 was not meant to be recovered/reused. But the starship booster did have a successful separation and did its job. Unless the loss of the Starship later was due to some issue or damage caused during the hot-burn separation stage. Then technically the booster did what it was supposed to do. If test 3 manages to have a successful separation the Starship survives what it is intended to do for the test. Then that will boost my confidence in SpaceX. Even if the booster is lost again. Though ultimately I would like to see them recover and one day reuse like the Falcon-9 Heavy Boosters. The Falcon-9's amazing success is one of the reasons I still support SpaceX. That is quite the accomplishment of boosters. I have faith in the SpaceX engineers. What I do not have faith in, is the BS Elon tends to spill when he opens his mouth. He makes huge promises that seem like they will change the world, only to constantly say "Hopefully by [insert next year here] we will have it in production." When you look at these billionaires who have so much power and sway over the world and their decisions. It is not genius I see. They are shrewd grifters who gained wealth and thus power. Hopefully though some good will come. I certainly hope SpaceX has success. Elon Musk can suck it.Vor Tag
Something I've wondered, is it possible sometime in humanity's future that enough rockets have been launched that the pushback from them becomes a measurable decrease in the earths rotational velocity?Vor Tag
It’s immense that whilst being a CEO of numerous companies and having to deal with the thinking required to cover what a CEO does…he still has enough cognitive bandwidth and technical knowledge to understand that what the DE-filmr points out can solve an important technical/performance issue and make a big positive difference. I’m sure there are some technical experts at SpaceX solely focused on these technical issues who are face palming because they didn’t think of thisVor Tag
Love ElonVor Tag
I'd be interesting to update the reliability numbers again now. The Merlins must be among the most reliable engines ever by now.Vor Tag
How can you compare the price of 1 engine vs. 1 engine when the Starship needs more of dem? That comparison is misleading.Vor Tag
Remind me of one of those bike pedals that sends you straight to hell when it accidentally hit your shinVor Tag
Tim i tried to get in contact with spacex, have an idea, and a solidworks approximation. Also trying to build a physics simulation in python to prove it.Vor Tag
Scrub might be the weirdest word in the English, where most of the time it does not mean, what the word actually means: To wash with a rubbing motion, but all kinds of weird stuff, so a terminated launch is scrubbed??? Or your can scrub around in a film editor (while it just means to repositioning really)Vor Tag

I wonder how much more thrust it had than the Saturn, an areospace senor told me once Lockheed bought a ton of N1 rockets when wall fell and said the tech was way ahead of NASA stuff.Vor 2 Tage

Get em bud!! In your tone when you said" But this is only for the booster right?" you knew exactly what you were saying, or am I wrong? I think it was ACTUALLY your idea that you somewhat passively implanted in his brain and he thought it was his thought. Get em!!Vor 2 Tage
