Yeah, i looked it up. The fuel required to do a recovery burn limits the gross max weight of the payload. Trowing the Center Core away gives lots of additional power. To cite Wikipedia (probably old Numbers, but will give you an idea for the size of the gains): "When recovering all three booster cores, GTO payload is 8 t (18,000 lb).[1] If only the two outside cores are recovered while the center core is expended, GTO payload would be approximately 16 t (35,000 lb).[69]" So they double the payload by trowing away just the center booster. If they go fully expandable, they can even bring 27t to GTO, but the only Missions that need that kind of performance are Europa Clipper (6t to Jupiter, barely within a fully expandable FH capabilities) and likely Gateway (>20t to the Moon, sure the Gateway propulsion module could take some of that work, but my guess is NASA will rather pay those $50M extra to save its fuel for lunar maneuvers). |

FH gets even more complicated when you compare it to a fully-expendable Falcon 9. Since they only have 2 barges on the east coast, they can't land all 3 stages on the barges. (without buying another or moving OCISLY to the Atlantic) That means you are limited to RTLS profiles for the side boosters. That dramatically limits how much payload you can toss if you also recover the center core. (And remember, they've never successfully gotten a center core back to Canaveral, even when they've tried) That limited capability means that the gap between a fully-recoverable FH and a fully-expended Falcon 9 is narrow. And since we've never gotten a center core back, and there are numerous long-serving F9's... well, you're probably going to lose a booster anyway, might as well plan on it. You'll note that there have been a number of F9's flown expendable. FH's real capabilities are unleashed when at least the center core is expended. That's where it's a beast. Fully recoverable, with RTLS side boosters... It's still a big boy, but it's not huge. |

While out west of Tubac, Arizona on August 7 shooting jellyfish sprites to the south and lightning to the east, I also turned another camera due west, looking straight towards Diablo ("Devil") Mountain. To my surprise the Space X rocket launched out of Vandenburg, California and arched over the mountain like a rainbow. These images are part of the timelapse sequence I captured, but I wanted to share two of my favorite moments! I'm not gonna lie, there were moments that night were I was crying in awe and wonder. Someday soon I'll share the series of images showing all the bolts, sprites, and rocket images so you can see for yourself what I experienced. I'm positive I'll never top it.
