What Happens to SpaceX Second Stage?
Вставка

- In this animation we look at what happens to SpaceX's second stage! Are they littering space with empty rockets? And why do some rockets fall out of the sky and pose threats to populated areas while others don't!

What happens to the second stage 3:57
Why do objects burn up on Re-entry 4:43
*Although SpaceX claims the second stage has on board nitrogen thrusters for pitch, yaw and roll control. Using them to flip around in orbit is a speculation as they keep that information confidential.
Note: The physics and numerical data throughout this animation is in no way faultless. Theories have been simplified for comprehensibility.

One thing to note: One of the most difficult parts of estimating the effect of drag is that, if a stage is tumbling uncontrollably, the exact cross sectional area is constantly changing.
guess that explains why unpiloted debris from your craft never deorbits on it's own in kerbals.
100% reusability is the cure.
@@cjkula Actually, that's largely due to the fact that atmospheres in KSP have hard delineated boundaries (anything above 70km of Kerbin is in total vacuum) and that KSP simulates gravity with single body problem mechanics.
@@thejimmydanly and ksp wont simulate atmosphere entry if the part isnt loaded, unless if the orbit passes below 35km, in which case it will terminate at that altitude
Yer, the Chinese are great at this.
Hey UA-cam algorithm! Throw this into everyone's recommended!
Seriously man, you are 🔥🔥🔥!!
dude omg why your channel so underrated I guess it's part of growth, anyways excellent work really enjoyed it keep it up it'll be worth it
Thank you for this educational video about what happen to the second stage, I hope many people will learn from your video and not going to assume dumb thing Everytime they heard about something like this
Wow, I’m glad I attended your lecture today. Now I know and no longer speculate on the this subject matter. I know the facts.
Dude you just blew up on UA-cam. Great work sir.
thanks man
@@aaravp2248 WTF
he is talking about the channel user
Not you
@@Omkharche Are you sure?

This channel has been abandoned lol. Not a single video uploaded in a year 🤷🏻♂️
Great video & channel!!!
How does this Chanel not have more subscribers? This is top notch quality! Keep up the work
It's because this channel has been abandoned. There's only a few videos and the last upload was a year ago. That's why!
So underrated.
Nice videos, saw on my recommended, adding you to my space-related channels
Very very very very very underrated
I literally waited for 2 months for your video. Amazing. Also your last video was great too. I am pretty sure you’ll hit a million by 2022. Keep up the good work.
Nearly 40k at the moment and 2022 is almost coming to an end! Certainly a long way to go to hit a million. Can it be done in 2 month's. Hmm 🤔
Edit: and just to add, there hasn't been any other videos uploaded for a year so I think it's safe to say that million won't be achieved! Looks like this channel has been abandoned 😕
This is absolutely amazing
Once again !!
Ok 2:23 in and this is fantastic man hela great job scott manley would be so proud
OMG, I've searched everywhere to understand what happens to second stage! Thank you, sir.
Fascinating and so well produced!
I was waiting on this explanation, you did a great job!
This was excellent!!! Thank you!!! Keep up the amazing work!!
This is a very well-made video and a really informative channel!
Someone once said Musk was an idiot for placing the Starlink sats in LEO at an altitude of 550km because they’d eventually experience orbital decay, I never knew they had krypton ion engines to manually deorbit at their deadline.
New subscriber! Keep it up, your animations are amazing.
That altitude is a safety feature also, because of orbital decay. If a sat has a complete failure (rare) and ends up bricked, it’ll naturally fall out of orbit within a few months/years. 😁
Great explaination on this topic man. Glad I found your channel. Nice work.. Keep it coming!
Wow! You read my comment on your last video and answered my question!
Thank you so very much!!
Your channel has given me hope. The last time I was here you were below a thousand subs
I’ve got to say !!! That was really informative. Thank you for explaining it in the most simplest way
Great job. Very well put together. I enjoyed it.
The amount of variables is significantly more than I expected. At least in terms of drag coefficient
Precise, simple, nice animations, well done, it's a very good video!
Excellent video! A thorough explanation that was engaging and educational! Awesome work!
Answered all my questions, thanks!!!
keep up good work man. I'll try to find more subscriber for your wonderfull channel.
Excellent stuff!!!
Love that Raptor sound! 😖
Great job on this video. It answered all my questions!
Fantastic work here! Animations are superb!
Wow, subscription earned with just this one video. Looking forward to more! 👍
Fantastic explanation! Great job. Subbed.
Great video!!
Another great vid!!! Let's hope the yt recommendation gods will bless you
Amazingly clear explanation. Thanks for sharing.
great video! it wasn't to long ago that i thought about how or if Space X does it ( i played a lot of Kerbal space program at that time), since they never show that part in their broadcasts.
This is very informative!
Watched several videos on this channel and it's all very well explained and animated, you earned a subscriber
That’s super kind! Glad you enjoyed them!
ight ight i finally subscribed! this is interesting channel! thank you
Great Job, very well explained
subscribed ..really good
Hey... You are rocking man... Most underrated page. Pls keep posting more such technical and make rocket science easy to understand.
Excellent work
so well animated, good job
This was really really good
Seriously, wow.. thank you
Well done!
Even for people who know this stuff watching these videos is very fun entertaining and its also a quick revision . Keep up the good work.
Thanks for this amazing explanation. I learn a lot about unknown things like these but overall I never found an easy way to understand what happens with the second stage like you describe. Thanks a lot, greets from Argentina
that is the most fantastic animation I have ever seen on youtube.
Nicely explained!
Cool, always wondered 👍
I Love a more in depth description of Rocketry that this channel provides.
excellent stuff.
Thanks!
Wanted to know this… and you nailed it explaining
I need to start learning animations too for my channel. This helps explain everything so much easier.
Great channel here. Slight piece of feedback; (not that my English is good) but I missed some pieces of explantion due to clothered words. Might be me not a native English speaker, but perhaps a little more articulation on some sentences would help a lot.
I've always wanted to know this thanks
Thanks so much for explaining this question to me. I have wondered about the 2nd stage issue for some time now. Also respect to SpaceX for their safe disposal technology.
Thank u！
You win the internet today, sir.
Keep it up!
Great information. Further success depends on elocution.
Quality content
Thanks for the info! I was really hoping Spacex had a plan for their second stage. Now I’m even more impressed with their accomplishments!
thanks a lot
Fascinating channel
ALways wondered , what happens to the second stage . Did not know it did a de orbit burn
At last someone explains this question I had for a long time
You should explain the SpaceX starship system
Your intelligence is showing. Thank you for spreading it around. ☺️🤗
Danke!
Dude do about rockets and space videos dude I subscribed your channel you are really underrated
nice
Good vid
Not bad at all, sir!
the timimng couldnt be more perfect i asked from the reuseable first stage and got recomended this
I fallow lots of channels that deal with SpaceX and other space launch companies. This is the first one to explain what happens to the second stages for SpaceX. Now what about the 2nd. stages for all the others. Is it the same ? Thanks for the excellent video. Subscribed.
You should be a teacher. Very well explained . Thanks for the share👍🏻✌🏻🇨🇦
He would be a great teacher. You should teach this..
Thanks interesting.
Hey! What's your background music source? Sounds really calm, love it.
Bro your channel is seriously about to blow up! Love your content! Some constructive criticism for you is make to content just a bit more understandable, because some of the information that you talk about, you need to have a little bit of knowledge before hand. I luckily have a little bit of knowledge before hand, but have struggled in the science area, but still understand bits and pieces of what you're saying. Otherwise, I'll definitely be coming back to watch your video every week!
Use each second stage to construct a space station, they can all be designed to fit together like a jigsaw puzzle. plus anti gravity can also be used to generate electricity, keep the circular motion going in the same way we would keep a bicycle going with small pushes whilst generating power from its overall rotation. it would extend the distance that can be travelled by using the power generated as efficiently as possible. A similar strategy can be used to extend the distance satellite's can travel by rotating them on an axes in transit.
Count me as a big fan! 👍
Thank you for your excellent video. I have a follow-up question, what happens to all the stuff that gets burnt up in space, and is it toxic if it reaches the earth?
Hello, Thanks for this amazingly informative video. This has been a great help for my assignment. Can I please request for information on various materials used for the fabrication of components?
I miss the good old days when I could pledge 5 dollars to youtube channels like yours without going bankrupt. Brazilian currency is worth nothing nowadays. But I'll give you my subscription and share your videos with my friends. Awesome content.
Hey man! I hope things get better!
i learned something
how did you achieve the fire effect for the rockets and the re-entry of the crew dragon pod?
Its a 3D solid with wave modifier for motion and a very high emission factor. I added some camera blur as well!
less go
Did you stop producing :( your channel was so great
No I did not!! I. I’m working on a new video, but I’m very busy with work! Stay tuned!
What softwares do you use for these animations sir
long story short: It spins around, fires it's thruster to crash into the ocean at a specific place.
You could have just said, "It get's wasted." That would have done it for me....
Thank you! I have asked what happens to SpaceX second stage for years! Most people say that they just allow it to randomly reenter, so I asked why they didn't do a deorbit burn. The ignorant invariably said that they didn't do this. This was not satisfying to me. :)
Video idea: can you explain: how a Falcon 9 can withstand re entry by doing a re entry burn
...Varied gravitational pull of earth ....could you do a graphic there of please
