T’as pas bientôt fini les insinuations là, Juju va te donner congé pour paranoïa si tu continues. 
Bah, n’empêche que Fullmetal a raison sur un point : Space X n’a jamais communiqué officiellement (encore une fois, à ma connaissance) là dessus avec des chiffres précis.
Alors, oui Elon Musk donne des pourcentages, mais dommage que l’on ne connaisse pas les sommes engagées.
Bien oui il l’a fait.
" According to Elon Musk, the marginal cost for a reused Falcon 9 launch is only about $15 million. He explained that the majority of this amount was represented by the $10 million it costs to manufacture a new upper stage. It is not reusable (and never will be), so it is necessary to make a new one for each launch. The remaining $5 million include costs of reusing the payload fairings (Musk probably only counts fairing refurbishment costs in this scenario because it costs $5–6 million to manufacture a new set of fairings), helium, fuel and oxygen, and also the cost of recovering the booster and fairings. Most importantly, the cost of refurbishing the recovered booster is only $250,000, according to Musk. That’s a very low amount, which could indicate that the booster refurbishment process does not require much manpower, expensive hardware replacements or complex inspections."
…
"So what does it cost SpaceX to launch a Falcon 9? If Musk’s marginal cost figures are at least somewhat correct, SpaceX’s cost to a launch a newly built Falcon 9 is about $50 million. The company charges $62 million for a standard commercial Falcon 9 launch with a new booster, so the first mission results in about $12 million in profit. The second launch of the same booster then costs only the mentioned $15 million, which include refurbishment of the booster and payload fairings, production of a new second stage, fuel, the cost of operating a naval recovery fleet, etc.
SpaceX charges a little less for launches with a reused booster, so if the second launch carried a payload for a paying customer, SpaceX gets $50 million. That means the total revenue from two launches of that booster is $112 million ($62M + $50M), while the total cost to SpaceX is only $65 million ($50M + $15M). So SpaceX would have made $47 million in profit after two launches which can potentially cover the costs of at least three Starlink launches, which would then be basically free."
Dernier paragraphe :
« SpaceX facture un peu moins pour les lancements avec un booster réutilisé, donc si le deuxième lancement portait une charge utile pour un client payant, SpaceX obtient 50 millions de dollars. Cela signifie que le chiffre d’affaires total de deux lancements de ce booster est de 112 millions de dollars (62M$ + 50M$), tandis que le coût total pour SpaceX n’est que de 65 millions de dollars (50M$ + 15M$). SpaceX aurait donc réalisé un bénéfice de 47 millions de dollars après deux lancements, ce qui pourrait potentiellement couvrir les coûts d’au moins trois lancements de Starlink, qui seraient alors fondamentalement gratuits. »
Imaginez les économies lorsque, comme aujourd’hui, un booster Falcon 9 s’envole et revient pour la 9ᵉ fois !
