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!!

  • This is a great video. I love SpaceX and follow their rocket and engine development very closely. The way you explained everything was absolutely perfect and would help people like myself, or people who have never heard of SpaceX, understand these general principles. Well done!

  • Maybe this is a stupid question. Is it not possible to design a rocket nozzle that can adjust its geometry to compensate for the external pressure? Much like how aeroplane wings have flaps and slats, and how thrust vectoring can adjust direction and diameter, can they not engineer a similar solution?

  • With the second stage there is also a problem with the location of CG. Second stages natural tendency will be to return to earth engine side down so you would have to find a way to protect the engine on the way down. This can be done with a ballute that remains inflated all the way to ground to protect the engine and nozzle. Nobody has ever used a ballute in real life that I know of. Sounds like an opportunity to make another first SpaceX!

  • Next thing Elon needs to work on is variable shaped rocket nozzle. Why can't the nozzle change in size/shape through the launch profile therefore maintaining efficiency? I picture it like colander, where the layered leaves can move therefore changing the shape of the nozzle.

  • So where does the 2nd stage go?? Does it float out into deep space never to be seen again or burns up during a reentry. I wouldn't think they just let it float around the Earth like junk. To bad there isn't a Space Garbage truck cruising around collecting this rocket boosters.

  • It's an incredible video and explains a lot of points. However, at the end of it, it begs the question, a rather critical one come a new space age - why won't SpaceX let the second stage fall to the atmosphere and let it burn up instead of it acting as an addition to the continually increasing space debris, causing a threat to the entirety of space exploration ahead of it?

    Mayank GuptaMayank GuptaPrieš 11 dienų
    • Upper stages are routinely deorbited in a controlled manner after they deliver their payload. The few that aren't deorbit on their own within a few months (LEO orbits decay relatively quickly). SpaceX are actually very good about minimizing debris in orbit, using pneumatic pushers for stage separate rather than pyrotechnics.

  • Newton’s formula is F=MA. Mass times ACCELERATION, not velocity. Minor point as the fuel is essentially not moving relative to the engine, but the correct terms should be used. When you expanded the formula on the right you did correctly express it in terms of acceleration (m/sec² ) and not velocity (which would be simply m/sec)

  • Hey mister! You make absolutely fantastic videos with clear animations and easy to understand information. However, I do have a suggestion for you: when you narrate, please speak more slowly and try to articulate more. I am Dutch and pretty fluent in English in all different kinds of accents, but I often found myself skipping back 10 seconds to hear you say a few words again because you tend to skip over a syllable or two. Other than that: fantastic job on the videos and please make more! Kind Regards, Your New Subscriber ;-)

  • Q? Why doesn't SpaceX add three 1st stage Merlins to the area between the payload/capsule and 2nd stage booster? Then using a 180° rotation, slow down the second stage using the 2nd stage Merlin, upon decent, rotate 180° again to use the 1st stage Merlins to land the second stage. It would require an additional height equal to the height of the 1st stage Merlins.
