This is so true. I am astounded by the nonsense coming from other space channels when you can get a master’s degree watching this one. Almost every episode requires a pause/rewind cycle for more analysis of formulas and data tables. This is the channel I would take to a deserted island in hopes of launching myself back to civilization! (Ya, I know… my space suit would be labeled, “Captain Chum” based on the likelihood of success)

With an ever improving F9, FH was indeed a hard sell back in the day. I once heard that Elon Musk was about to cancel FH entirely, because development was hard to get funded. Apparently it was Gwynne Shotwell who kept the program going, because they already had customers for FH, i.e. heavy GSO playloads. Thanks for the summary. I think Artemis/CLPS will be FH's time to shine.

@judet2992 RS25 is a great engine, but because it was used on the Trash Shuttle, no single engine actually got used very many times. And now, the stupid expensive SLS is using them as expendable. 🤦 I heard they are/might start production of the RS25 again. But a slightly cheaper version since they won't be made to be reusable.

The bit about “extra work” reminds me, SpaceX has referred to a vertical integration facility to explain a couple >$300M launches of FH before but it’s yet to materialise. I wonder how progress on that is moving along.

I looked for info a while back and didn't find anything and I'm too lazy to go off and find which mission it was for. I don't think anybody has seen any work done - presumably they'd do it on 39A and just hang it near the crew access arm.

We must remember Elon's prime directive when thinking about SpaceX decisions. Falcon 9 and the whole family exists for two reasons: 1) get SpaceX smart on rockets and engines so they can build Starship for MARS, and 2) a side hustle to fund MARS. Elon dislikes Falcon Heavy and would have preferred not to develop Heavy at all. And DoD insisting both suppliers cover all weights just makes sense - you're buying redundancy with 2 suppliers - why accept less than full redundancy?

Great review of the history of this intriguing (to me) launch system. Really love the gems of interesting points and insights. For instance, going over the Falcon 9 Payload Adapter and its center of gravity limitations was worth hearing (able to support the launch of an 18,00 kg payload), as a factor for why Falcon Heavy isn't used for Starlink, and on why payload figures for the Falcon Heavy may be more theoretical at the moment (or require quite a bit of work).

they actually had plans for a heavy version of falcon 1, thought the idea was quickly dropped once they started work on multi-engine versions of falcon. Scott manley covers it in his video on Abandoned SpaceX Rocket Designs (kzbin.info/www/bejne/apiaammhnqx3r7c)

Lack of droneships could be solved with RTLS on the outer boosters
@SpaceAdvocate3 ай бұрын
That drops the payload to LEO substantially. If it can only do like 30 tons to LEO with all three cores recovered, the cost relative to a standard Falcon 9 becomes problematic. Falcon Heavy makes most sense with the two outer cores landing on drone ships and the center core expended, or fully expended.

@jgottula3 ай бұрын
That's the mode they've done the most in practice; but it's not the only way things can be done. There are actually quite a few ways FH can potentially work. A. Boosters RTLS, core drone ship B. Boosters RTLS, core expended C. Boosters drone ship, core drone ship D. Boosters drone ship, core expended E. Boosters expended, core expended F. Boosters RTLS, core RTLS I believe that these are all of the potential reuse modes for FH. (The letter designations are arbitrary things I came up with just to make them easier to refer to.) So far they have done: A: 3 times B: 5 times E: 1 time C needs a third drone ship. D is possible with the two drone ships they have now (since the core's not gonna land). But they haven't had a situation yet where they felt the need to do it, I guess. F is an odd one. It needs a third landing pad. And because the core is generally going quite fast and quite far downrange at MECO, the penalty for the boostback burn, to head all the way back to land, is pretty big. But it's apparently not so bad that it couldn't technically be done, if for some reason you really wanted to do that. (I doubt this is something we'd ever see happen.) (You could additionally do weird backward things, such as boosters to drone ship and core RTLS; but those don't make any actual sense.)

You might want to watch my "what do we do with starship?" video... The first answer is that Starship is a Starlink lifter, and that will probably be a very good customer. The second answer is that Starship will have plenty of customers if it's roughly the price of a Falcon 9 launch, which - of course - requires them to actually get second stage reuse working. But if they do, the economics take another huge shift.
@J7Handle3 ай бұрын
@@EagerSpace given IFT-4’s results, it seems it could be difficult to make Starship rapidly reusable, with lots of TPS damage seeming likely in the future, independent of the flaps issue. And with such an extended r&d process, the amortized cost of Starship is definitely mounting. Probably won’t be nearly as cheap as F9, at least for a 100 launches after going fully operational. Could still achieve a marginal cost of under 10 million per launch, but pricing will need to be 100 million+ to make a profit after all the r&d costs are accounted for.
