CLASS IS NOW IN SESSION 🎓 KSP Academy: Rocketry 101 with KSP2 Dev Matthew Poppe 🚀

[@KerbalSpaceProgramOfficial]

Apologies for the camera/audio issues, aiming to get these fixed for next time! Hope you all enjoyed, let us know if you want to see more KSP Academy!

[@Jambot0013]

It’s ok! I love your vids so much

[@Joris.01376]

Absolutely no reason to apologize! I had a great time watching that video!

[@AJsarge1]

The audio was good! Quiet, but good! The only thing I'd change, is to have a center group mic so that we can hear your "students" more clearly.

[@jjeeqq]

Very nice. Waiting for new lessons. One thing which probably wont be in-game anytime soon i have been wondering : how nasa used to navigate their moon lander to surface within cockpit using only instruments and how they were able to rendevouz at mun orbit with return capsule.

[@GizmoMagui]

its ok, as humans if we ain't learning then what are we living for...

[@retrogradevector]

Love the glimpse of the wallpaper at 49:14, with the delta V to reach various planets, even ones in other solar systems that haven't been released yet! Seems reaching Neidon's surface (intact) will be quite a challenge ...

[@jasonsteelman5106]

I could not be more excited to go see another solar system!

[@churchseraphim1380]

Neidon is the outer planets mod from KSP1. That's a delta V map from the mod page

[@notsofrenchy]

@@churchseraphim1380yes but he also says “leaks leaks leaks” which implies that the delta v map is relevant to KSP2 and not just OPM. I wouldn’t be surprised if they had some modded content from ksp1, since many of the developers are also ksp1 modders.

[@churchseraphim1380]

@@notsofrenchy I mean... maybe... but I think it's more likely that he's talking about the internal developer slack open. I def don't think OPM will be in the stock game as I don't think Poodmund would allow it and the original OPM dev fell off the face off the internet and it's license states not for commercial use... as much as I would love OPM to be stock because its so stock a like

[@alexhigginbotham8635]

I'm really looking forward to KSP2 implementing multiplayer. It'll be great fun to play with friends.

[@siedliko]

I wonder how would Multiplayer work? 2-4 people at the same time will be fine, but more people with time acceleration will be difficult

[@alexhigginbotham8635]

@@siedliko - It was already supposed to be a feature at launch... but we saw how that went.

[@TheSandboxMaster]

Wasn't verified to be at EA launch, only in the full game launch.​@@alexhigginbotham8635

[@mushylog]

@@alexhigginbotham8635 The game was released in Early Access, so indeed we saw how it went: it wasn't a full 1.0 release, they made that clear, my friend

[@Splarkszter]

I don't trust the cow milking megacorp behind this, Take2 CAN'T be trusted. Don't buy promises.

[@jjer125]

KSP academy is such a fire idea and very well executed too. Slides are cool, chat interaction is well managed and the in-the-room audience and questions make the lecture feel lively, which can so often not be the case with virtual presentations -- I only wish that the room people were also mic'ed (might just be audio issues but).

[@billsanders4933]

Specific impulse is how many seconds you'd have to spend accelerating in free fall at 1G in order to be going the exhaust velocity of the engine.

[@Meatloaf_TV]

I always wondered how they came up with that number

[@billsanders4933]

@Meatloaf_TV I don't know if that's how it came up; I think it was useful to have a way to represent exhaust velocity that didn't depend on imperial vs. metric. I just like it as an intuitive way to think about the number, even if it isn't very useful.

[@SodaPopin5ki]

I'm not sure if it's equivalent, but another way too look at specific impulse is how long a kg of propellant will last producing 1kg of thrust. A longer specific impulse means the propellant lasts longer, and hence is more efficient. Interestingly, another reason its given is seconds is so there would be a universal "unit" for exhaust velocity used by American and German transplant rocket scientists, instead of converting between feet per second and meters per second. You just divide the exhaust velocity by either 9.81 m/s^2 or 32 ft/s^2, and you get the same number in seconds.

[@RonRPL]

​@@SodaPopin5ki So only Americans and Germans do build rockets? No one else?

[@retronexusnet]

excellent series! please continue this series! There is so much to learn

[@madlep]

This is possibly one of the best KSP theory videos I’ve ever seen, and reminds me of me rambling at everyone about orbital mechanics and rocket physics every chance I get since 2011 because it’s so damn cool and interesting, except without the bit where everyone tells me to shut about orbital mechanics and rocket physics already 😂

[@linustiedeken1817]

Man even as an regular KSP Player i love the style of explanation and drawing in this viedeo. Pls make Rocketry 102 accessible for the public.

[@oldmcg7791]

Yes that is what I’m looking for too. Wants refresh my brain beige teaching some kids on it.

[@mechbfp3219]

Finally got to watch this and it was great and very accurate. I personally forgot the drag was squared to velocity and that curve when dropping stages during launch to attain a roughly average “ideal” TWR curve is a very good visual that I personally have never seen a visualization for.

[@TheRealJupitz]

Really informative and well presented! Kudos to Matt!

[@SystemBD]

This is relatively simple stuff, but it is really well explained.

[@ICodeMonkey]

This was great. Please keep them coming.

[@invasion9786]

Great video. Can't wait for the next one!

[@WibblyWobblyChannel]

Never getting a next one sadly :(

[@nubnoobbo]

about that...

[@Climberfx]

Love it! Thank you! I'm an older player from KSP1, builder of the Omicron Flying space car MOD, love the practical physics and your board synthesis. Thank you for sharing.

[@Vijaya7225]

Just loved it.

[@Fallub]

Great video. I love to learn all of this.

[@Fryguy101]

Good stuff! Can't wait 'til we get to interstellar!

[@TheJamster1234567]

Super great, can't wait for more. I'm excited I finally know what isp stands for lol

[@kharlanvitaly]

Finally I get somewhat understanding what Isp is! Thank you!

[@bs3156]

Super helpful and informative. Feels like being back in school with a teacher that is passionate! Can’t wait for the next one 🎉

[@lextacy2008]

I will watch this while playing KSP 2 at the same time!

[@razovsuki]

That was really informative and fun to watch. Moar please!!!

[@geraldimhof2875]

A very easy way of imagining ISP is: how good your engine is at transforming each unit of propelant into high speed exhaust.

[@akwakatsaka1826]

Please upload more of these lessons on KZbin !!!

[@hey_how_are_ya]

I am very sad that I had to miss this live stream but I really hope that there will be another one. Ive been wanting to relearn how perfect orbit satellites to have constant communication with each other without the planetary body interfering.

[@Jofire101_Grogu]

It’d be amazing to have a section of the training center tutorials of KSP 2 be just mini clips of these videos of each topic, for those who learn better with visuals rather than hands on!

[@johnburr9463]

Tim Dodd and Amy Shira-Teitel did the ice rink experiment with fire extinguishers.

[@DavidSpok]

R.I.P.

[@Link2edition]

I am a mechanical engineer who works on space stuff and I love this.

[@uiytt8497]

Very interesting to learn of this in such an interesting way

[@Isaac_Brock]

Love it, looking forward to more advanced topics.

[@connorvickers2053]

Thanks for the nice lecture Kerbal Poppe! I can tell you this, the "scary stuff called calculus" is a very accurate way of describing calculus in this context. I once took a course that "taught" us orbital mechanics, and it absolutely sucks

[@docandersonshow]

Yes. Moar! I have missed this kind of content back when we got it from Scott Manley.

[@jeeper1]

All this is still good for ksp don't stop

[@jasonsteelman5106]

I'm just jealous that your TWR readings work. On my computer they always show zero, no matter what I build.

[@PTNLemay]

The "older recruit" looked kind of like Adam Savage

[@bladrbrettel6511]

Nice one. It explain a lot of what we get to know playing the game and put words on it 😄

[@Runescope]

To stay in orbit, you have to throw yourself at the planet with sufficient speed and miss.

[@JoeyEintagsfliege]

More of these videos! Great! Thanks! :)

[@aeterosofficial]

Thanks for sharing this, very nice slides.

[@marianavazquezosorio3438]

🎉🎉🎉🎉🎉🎉we want more KSP Academy👍

[@johnburr9463]

Perfect explanations and examples! Whenever one of my 12 sisters asks me another one of these questions, I'm just going to send a link to this video.

[@abdelhakimchibani4712]

Loved it, will there be a next one with more advanced concepts? Maybe also introduce some maths?

[@themris]

This was awesome! Nice work

[@ossa701]

Great video, thank you!

[@TheRocketForge]

I once made a Kerbal take one-hundred-thousand G‘s

[@frogbeerr]

If you move sideways, the ground curves away beneath you, because Earth is a sphere. Unfortunately you are also falling down towards the ground. But if you go sideways fast enough, the ground curved away further than you are falling. So in a sense an orbit is the art of falling down and missing the ground.

[@gregdeen1469]

Waiting here for part two to come to ps5. Been a long time since I've seen or heard any updates on counsel release date.

[@martinbatora]

This is awesome!

[@bolloxim1]

ultra spicy : almost a 1 million isp.. ooooooo ... ahhhhhhhhh

[@sergeykanashchuk7671]

Do you even know your audience with your "next week's stream is going to be more fun and less science"? Science is fun! Anxiously waiting for for Rocketry 102 and I'll bring a notebook❤

[@Jambot0013]

Your vids are the best

[@TheArchaicFuture]

This is gonna rival colleges and 5 years in the future 2k hours of ksp1/2 will equal a bachelor's degree

[@TheBenlueks]

i wish this game existed when i was in school. i would have wanted to be a rocket math person! lol

[@mattygee79]

I love physics

[@electricminecrafter]

b4 you guys do that can u plz fix the bug where ion engines don't work at time warp in kerbins SOI?

[@Deino-1]

@kerbalspaceprogram These look like Paul Hewitt's Physics I illustrations. Was he an inspiration to you?

[@P4INKiller]

Why did you remove your recent stream?

[@RobFeldkamp]

Orion Drive!!!!!!!!

[@Runescope]

The answer to how Isaac Newton knew what equations to use is that he copied them out of a textbook from a Persian Mathematician who had worked it out a couple hundred years earlier. lol

[@SystemBD]

Interesting. And it would not be the first time something like this happened... But do you have any proof?

[@Runescope]

@@SystemBD I wish I could remember where I read it, but it was in some paper on some scientific website. My brain has never been good for remembering details, which is quite annoying let me tell You. I'm sure it's googlable.

[@Antosman-im6xk]

Hello

[@bryanmyers9977]

TWR = Sanity Forget that low TWR stuff he said ;-)

[@deinemutter1518]

a really nice presentation, but it definitely lacks of funny hats !

[@Knitret]

Camera lagging as the KSP2

[@ObsidianCorgi]

Ааааа новый ролик

[@glampstronzartonalbee3097]

Lost intrest with 2.0, feel like they missed the mark when it released

[@SystemBD]

The thing is that they haven't "released" the game yet. It is in "early access" (probably, because the publisher forced them to because of the complicated development of this title).

[@levastohasarrived]

Ksp 2 is good but my pc to poo for Ksp 2

[@ThePuccagamereditor2023mpg]

Bol

[@alecisla]

All comments asking about new content... what about fixing all the bugs first? Coz more content will bring even more bugs, that's for sure! 😕

[@dab4762]

give me multiplayer please im desperate

[@razorback8300]

It’s at the end of the roadmap . So probably in 2 - 3 years

[@Frisson97]

And?

[@Дмитрий-ф9в1м]

Отвратительная кампания

[@johngreen4152]

Guys, people here KNOW how to play your game. So, instead of telling us these things, MAKE IT PLAYABLE.

[@topster888]

Just let us know when KSP2 has more features and works better than the original. Until then, no one cares.

[@orleansjunky4074]

Stick to making the game. Leave the pro streamers to these types of useful/useless information.

[@bensharpe64]

Letting the marketing artist explain some game mechanics isn’t going to hurt anything.

[@jjeeqq]

This is literally parts of their game mechanics

[@Joris.01376]

Why? I think they do a great job at exactly that.

[@iveharzing]

Matthew said that they do these types of presentations anyways, so they thought: why not stream it? It literally doesn't negatively affect the development of the game. And I did find it useful.
