SpaceX is good at PR. | ||

If that is the reason, why not use a stable platform instead of a ship? (Cost?) | ||

And a stable platform is at exactly one place. You can put a ship where your trajectory will lead the rocket to land, and correct a bit if stuff doesn't go exactly as planned. | ||

(Cost?) Landing the 1st stage is only secondary to launching the payload successfully. For certain high orbits or heavy payloads, there's not enough fuel left to fly the stage back to the launch pad, which is where the barge comes in. The barge is over 90m long and 50m wide and basically ignores most waves. The really interesting launch will be the Falcon Heavy in a few months, when all three stages are gonna touch down (boat and pad). | ||

They failed 3 barge landings and it was a huge achievement they even soft landed this one given the high waves (go watch the stream before it froze, watch the horizon and how much it changes, it's ridiculous). This was also the last f9v1.1 that flew and it was not going to be reused, ever. The newest version (the one that landed) already has better legs. As for "SHUTTLE LEVELS OF RE-USABILITY" stop taking a dump on the thread and follow up on all of the news, not just the ones that serve your point. They static fired the rocket that landed without any work done on it (it was still dirty even) and only one engine showed minor fluctuations. Out of 9. That is way beyond any re-usability shuttle has ever demonstrated, it was considered a miracle by some engineers that the shuttle turbo pumps never went kaboom on a flight and they had to be replaced after EVERY SINGLE flight because they couldn't possibly handle 2. e: AFAIK they landed on a barge on this flight because they didn't have permission to return to launch site. landing video: https://www.instagram.com/p/BAqirNbwEc0/ | ||
