    I just realized... with two boosters returning simultaneously for the first time we'll have video if a booster returning from only a few hundred feet away :) One booster can stream video of the other booster.

    I too am excited about this. I expect to have some stuff going up on the second Falcon-H launch from the Cape. I think I'll drive my Model S cross-country for this one. I do hope they attempt the triple landing.

    You "expect to have some stuff going up," that must be a pretty spectacular feeling. Congrats!

    You must have some involvement with:
    A SpaceX Falcon Heavy rocket will launch the U.S. Air Force’s Space Test Program-2 mission with a cluster of military and scientific research satellites.

    The Falcon Heavy launches are something I've looked forward to since I first saw their video simulation a few years ago. CANT WAIT!!

    I haven't witnessed a launch in person since seeing STS-92 (Discovery) go up in October 2000. Plan to take my son down to watch Falcon Heavy Make history.

    It will be a triple landing for sure. The first Falcon Heavy flight is for testing/demonstration. Expect it to be in Dec of this year or early next year.

    For me personal, I am more excited about what Elon will reveal in September about the detail plan to get to Mars. Including the Mars rocket which will be larger and more powerful than the Saturn 5 rocket. It will be the biggest rocket human has ever made.

    Yes I am eagerly anticipating Elon's presentation this coming September. However, the Falcon Heavy is a necessary step on the path to preparing to send humans to Mars, and the FH will be used to send Red Dragon capsules to Mars in 2018 and for several years thereafter. So I am looking forward to seeing FH flights in the near future!

    In the "Elon Musk" thread on TMC, some have posted that Elon is "all head and no heart". Elon's repeated statements about his Mars colonization goal, that it is driven not just by a rational analysis of the need to ensure that humanity does not remain bound to earth (with the attendant risks of that scenario) but because human exploration of our solar system would be "the greatest adventure ever" (his words) reveals that he also values the emotional experience of venturing literally "where no man has gone before" (to quote a line from the original Star Trek series). I'm totally onboard with that!

    Elon said in the Recode conference that he will launch a mission every 26 months starting in 2018 (2020, 2022, 2024...) since that's the time frame where earth is closest to Mars. Definitely excited about that.

    I wonder what kind of launch would allow a triple landing... it would have to be a very very heavy launch into LEO. Seems like cargo like that (like a payload to Mars) would need to get to GTO which means a sea landing... unless it catches Florida after a circumnavigation.

    I'd expect two stages back to Florida with the center one landing at sea if they're going to use anything near the full capability.

    SPACEX MAIDEN FALCON HEAVY LAUNCH MAY CARRY SATELLITE IN NOVEMBER

    This suggests to me that if SpaceX decides to recover all three boosters that the payload for GEO would have to be rather limited.

    SpaceX undecided on payload for first Falcon Heavy flight

    Here's some comments from Gwynne Shotwell, SpaceX’s president and chief operating officer:

    So I interpret this to be if SpaceX wants to demonstrate the maximum heavy lift for GTO that none of the boosters might be recovered. On the other hand if they want to make the flight "useful" in carrying a client's payload and demonstrate reusability, then they would have to greatly reduce the payload.

    Yep... whenever they return the booster to the cape it's always a LEO launch... I don't see why a Falcon 9 wouldn't work for a LEO launch. The payload to LEO for the heavy is twice that of the 9 so you're using 3x the rocket for 2x the payload...

    They can recover all 3 boosters but it'll be 2 by land and 1 by sea.

    An alternative theory is that SpaceX would take a client's civilian payload all the way to geosynchronous orbit, not just GTO. DOD, NSA, etc. are quite interested in such a capability as I understand it.

    Depending on the mass of such a satellite, it might well be possible to recover all 3 boosters, although, again, one might be at sea.

    So the question is: how much does the fuel cost compared to the booster
    AND / OR: How much does the fuel cost compared to the extra cost of launching one booster, then cleaning and re-testing it...

    Wasn't there a famous quote in history?

    2(if) by land and 1 (if) by sea... (or visa versa?).;)

    This article mentions Musk's estimates for fuel costs:

    SpaceX's reusable Falcon 9: What are the real cost savings for customers? - SpaceNews.com

    quote:

    Musk said the fuel used on a Falcon 9 is between $200,000 and $300,000. Reserving fuel in the first stage for landing adds mass to the vehicle and deprives it of performance, effectively carrying fuel instead of extra payload — a penalty that expendable rockets do not need to pay. Musk was addressing not the performance penalty, but the issue of fuel cost, which is a non-issue in the overall economics of reusability. - See more at: SpaceX's reusable Falcon 9: What are the real cost savings for customers? - SpaceNews.com

    end quote.

    Rest of the article talks about booster costs, etc... Don't know if that answers your question.

    Have they considered a split reusability/expendable operation? Seems to me they might be able to return the two boosters even if they can't recover the core.

    I am sure they did. It might be necessary to launch a FH under conditions where the middle core cannot be retrieved: Severe weather in the landing zone, preventing the drone ship to operate. A demanding mission where the core takes excessive damage during reentry burn and needs heavy refurbishment - I would consider this a partially expended core.

    SpaceX to lease building at Port Canaveral, may build another one
