    1. I’m pretty sure the centre core is being expended on this launch; I think that’s the reason they’re landing the side boosters at sea, they need the extra payload capacity.

  1. This mission is direct GEO insertion, not the usual GTO transfer orbit, it takes a lot more Delta/v.

    They’ll almost certainly have to expend the center core. Another limiting factors is that SpaceX has just two ASDS landing platforms.

    Speaking of Falcon Heavy, I’m still hoping it gets the Europa mission. Right now, it looks like the Europa probe will be completed, and then mothballed to wait for SLS availability in 2025. (FH would need a 3rd stage, and that development won’t come cheap, but, far cheaper than SLS, plus FH has the added advantage of actually existing).

    And speaking of SLS, there’s news that the latest GAO reports mentions a concern about a potential Green Run obstacle; SLS might leak. I’m going to guess that by “leak”, they don’t mean hydrogen escaping at startup (the cause of the flames seen at Delta-4 And Delta 4H launches) because the RS-25 engines SLS uses didn’t do that on Shuttle.

    1. It might not be a huge job to fit a solid kick stage to it, if that’s enough; maybe a Star-48 could do the job. Probably more work for the navigation planners, but computer.time is cheaper than hardware development…
