Better build a few more as 100 flights seems pretty high (may have been simply increased to match Bezos spectacular claim. He's probably confident that his rockets are more reliable). What’s bezos’ claim? Quote Link to comment Share on other sites More sharing options...

Bezos says each NG first stage should be capable of 100 reuses, but makes no claims as to refurbishment timeframe or sequence. 18 minutes ago, tater said: My god that will be glorious.

sevenperforce Posted May 10, 2018 Share Posted May 10, 2018 10 minutes ago, tater said: I bet the "how you count it" is whether you include the static fire propellant in the total or not. Musk has said the payload fairing costs around $6M. So we finally have (rough) numbers: Payload fairing: $6M Fuel and consumables: $0.5M Launch costs, not including fuel: $5.5M Second stage: $12M Booster: $36M Total in-house cost of expendable launch: $60M If SX sells an expendable Falcon 9 launch for approximately $95M, that means they're looking at a 37% profit margin. If we guesstimate Block 5 recovery costs at $1M per flight and assume only 10 flights per booster, then nominal in-house cost per flight is $28.6M. If they continue selling recoverable launches at $62M each, that's a 53.9% profit margin. They are about to make so much bloody money..........

tater Posted May 10, 2018 Share Posted May 10, 2018 Or that’s retail, and their cost is substantially less. Quote Link to comment Share on other sites More sharing options...
sevenperforce Posted May 10, 2018 Share Posted May 10, 2018 Oh, and if we assume, reasonably, that the $1M/launch in recovery cost is more than enough to allow for more refurbishment every 10 flights, and accept Elon's claim of 100 reuses per booster, and assume they get fairing reuse sorted with an average of 20 uses per fairing, then the nominal amortized cost per flight becomes $19.7M. 6 minutes ago, tater said: Or that’s retail, and their cost is substantially less. Elon described the payload fairing as a "pallet of $6M cash falling out of the sky" so it sounds like that's their nominal in-house cost.

Just wait, there is still a chance. Why does the backround noise sound like a restaurant? I hear typical metal object noises (forks, spoons, and knifes) in the backround.

Of course not, this used to happen all the time in earlier missions. It seems that they've had less of those recently, though. Quote Link to comment Share on other sites More sharing options...
