    The dual landing of the side boosters was spectacular.. touchdown within a second of one another

    It is impressive. Sounds like the main stage had inadequate fuel to achieve the same relanding. I suspect they'll fix that.

    You are right.. not enough fuel

    "...But the center core booster ended up hitting the Atlantic Ocean at 300 mph and about 328 feet from the floating platform where it was supposed to land. Musk said Monday that there wasn't enough ignition fluid to light the outer two engines of the booster "after several three engine relights."

    Probably wet wood.

    This whole thing makes the landing of the Apollo 11 lunar module and take-off of the ascent module 48 years ago all the more impressive.

    I think they are both very impressive, each for its time

    That simultaneous touchdown was way beyond 70s technology.
    The very idea of a Saturn 5 as a one off throwaway vehicle speaks of another era of fiscal profligacy.

    We are witnessing anew era of space exploration. The closest competitor (the delta heavy) costs 5 times as much ( 450 vs 90 million) and can only lift half the weight to LEO, and throws away the rocket

    The other arrow in the ULA quiver, the Atlas, relies on the Ruskie RD 180..Maybe Jeff Bezos can replace it... but it has yet to fly

    NASAs current effort, the SLS,has yet to fly, will cost 10billion in non recurring costs, and 1billion per flight. It can carry 2x as much as the falcon heavy to LEO

    But do the math.. roughly 100times the per flight cost to first flight and 10 times the cost per flight... which plan will get you more out to space

    Cost performance and schedule... the elements of any big project.. Musk has clearly mastered the first two... and he hasjust started

    I'm a fan. Sounds like you might be too.
    There are very few people that have made the kind of positive impacts that he has. He could have taken his gains from PayPal, bought an island, and retired. Instead he has invested in truly disruptive technologies that I feel will ultimately improve our lives and the world we inhabit.

    Yeah the contrast with Branson is stark.. playboy vs contributor

    And yes, I'm a fan of his space efforts and industrial batteries

    Musk has a why to his existence and it is not just money.
