@subboid Nobody said re-usable rockets would never happen or work, The problem with reuse is that it is not very cost effective. it is merely a saving of about 10% which in return your payload capacity with the initial launch is much less, because u need fuel to land the stage. Also SpaceX failed to reuse the entire vehicle. Soft landing dragon was canceled and re-entering and landing the 2nd stage for reuse was also canceled so Flacon 9 is only partially re-usable.. The turn around time for a stage is still about a month which is only marginally faster than with the space shuttle. even inflation adjusted the cost to launch a astronaut to the ISS is about 20 million dollars more expensive now than it was in 2010. So no i don't see any great improvement here with reuse, besides launching payloads to LEO isn't anything new, it has been done since the 60's and more reliably since the early 80's.
