In this animation we look at why SpaceX doesn't recover and reuse the second stage!
SpaceX has made getting to space much more affordable through reusability of its first stage. Why don't they recover the whole rocket and make space that much more affordable?

Thank you everyone for engaging with this video through views, likes, suggestions and very kind words! I'm really glad to see many of you enjoying it!! Creating these animations alone from start to finish generates an array of challenges like balancing music/voice volumes, depth of details and number of topics covered. I appreciate the suggestions! Stay tuned as another animation is in coming together quiet well! As for the second stage, I believe they are left in their orbit to eventually fall back into the atmosphere where they burn up. Cheers!!

Funfact: the less aerodynamic your pod is, the better. It is pretty counter intuitive but you want to compress the air infront of you. If you do it right the air will form a manageable 300+°C warm cushion that keeps the melting hot air away from yours ships/pods surface.

@zteaxon7787 2 года назад

What if the second stage deployed a kind of wings which gradually allow reintroduction into the athmosphere over the course of let's say 2 earth rotations? That way the "trauma" of reintroduction can be limited? I don't believe the added weight offsets the needed capacity that much. It may well be worth it compared to sacrificing such a massive investment for every launch.

@melhitchcock4051 Год назад

@@yallowrosa Hi yallow rosa. So did you miss the whole point about the second stage being at orbital velocity? It would not simply roll over and return basically to the launch point as does the first stage. It would need to be designed to withstand the very high heat of the supersonic re-entry and somehow "flown" back to a recovery point on earth. Also, the second stage motor would not be usable to perform the landing, as with the design of the first stage motor, as it is optimized for use the the vacuum of space, and would self destruct if operated in the lower atmosphere. Do you still not see why the second stage is not feaseable for recovery?

@alrightydave 3 года назад

Very well explained video! The only thing I’d add would be that, re entering from orbital velocity is not 4 times hotter than coming in at 2km/s in the case of a Falcon 9 booster. Re entry heating goes up by the cube of velocity, so a second stage coming in from orbital velocity would experience 64 times as much heat as a sub orbital falcon 9 booster that is only traveling 25% of the second stage’s velocity. That’s a very important thing to consider.

Like a skirt above the engine, that would be lowered to extend the small skirt?

@the65thpotatooverlord15 3 года назад

IIRC, the decoupler pushes the second stage away. Since the second stage is lighter, the energy from the separation slows down the first stage by a little and pushes the second stage away.

@morningstarkid07 3 года назад

There is a big piston on the top of the first stage that goes up into the 2nd stage engine. when it's time to separate they use compressed air to extend the piston and push the 2nd stage away. Here is what the piston looks like: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-RBxkRKZ34yo.html This view is from the top of the 1st stage looking up into the 2nd stage engine bell. It's hard to see the actual piston extend because it doesn't really move that far. It just needs to give a quick solid push and inertia does the rest.

@morningstarkid07 3 года назад

It's not really a decoupler. It's actually a big piston that's mounted on top of the first stage and reaches up into the 2nd stage engine bell. You can see it in their live broadcasts. Heres the view from the most recent starlink mission: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-RBxkRKZ34yo.html

Wow! It´s very difficult to explain such a difficult topic in a simple way, it´s wonderful. Congratulations, the animations and explanations are great. This video answered a lot of questions I had long time ago and I could not understand until now, as I didn´t find the proper explanation. Thanks a lot!

I think 3Elon has said that it is cheaper to manufacture a 2nd stage than to get a recovery vessel to pick it up

If it fully burns up then it's fine because we gotta be careful with all the space debris...

How about tempering and heat treatment of Iron and it's effects on the strength of a say blade?.... Along with explaining the different types of tempering techniques used throughout the ages (japanese Steel 👌)

Love the ideas! I aim to create content that is very applicable to the every day person to increase engagement, but that’s a topic that would be extremely beneficial to have an explanation through 3D animation

They have it reenter the atmosphere where it burns up in a safe place. This is standard practice in the space industry unless you're China, in which case you just let it go wherever it wants and everyone else can hope it doesn't land on them
