    SpaceX finally lands rocket on a barge

    They did it !

    Crazy stuff - I'm very impressed because they made it look easy. The drone ship is rolling around in the waves a bit too, just to make the rocket science harder.

    Re: SpaceX finally lands rocket on a barge

    Not just the landing, but landing on a relatively unstable platform and staying upright after the rocket shut down. I guess the CoG must be quite low down, and there are the spreaders at the end, but still very impressive.

    Re: SpaceX finally lands rocket on a barge

    I suppose some interesting commercial questions now get raised...

    How much can you charge to ride a second hand space craft.

    Will the insurers touch it?

    Nor really second hand though, just multiple use, it will be refuelled. In principle it is no different from refuelling your car or having a manufacturers service, or perhaps more appropriately, flying in an aircraft that has been stripped and rebuilt as part of its maintenance regime.

    It will be refurbished (serviced) refuelled and used to launch another vehicle..

    Re: SpaceX finally lands rocket on a barge

    Ah yes, but imagine if no-one had ever refuelled or serviced a car before. Even though it is designed for it, there will be an interesting talk with the insurers for people buying the next payload because insurers don't like anything new (or possibly they love it as they can charge double).

    SpaceX are saying it'll reduce costs by 30%. SES want to be first to launch on a re-used Falcon 9 but they want a 50% reduction. - http://spacenews.com/spacex-says-reu...y-in-november/

    What I find most exciting is that Musk plans to launch the re-used first stage within 2 months. He's got to be pretty confident to say that! http://www.theregister.co.uk/2016/04...in_two_months/

    Yep, when the fuel's gone then the weight is all low down. Someone did a lovely estimate of the CoG and critical stability angle - http://space.stackexchange.com/a/9199

    Can't really argue with the accuracy or logic in that. Looks very stable to me. I'd still be nervous about it landing in high side winds.

    Re: SpaceX finally lands rocket on a barge

    It seems like a really big leap forward for them, one step closer to eco friendlyish and simple space travel

    Seems the drone ship has docked, so some on board camera shots have been released.

    Re: SpaceX finally lands rocket on a barge

    Sounds like the next one should be interesting, less fuel and harder landing:

    they like to make it as easy as possible for themselves don't they?

    I did wonder why they wanted to do it in the sea...
