kerbiloid Posted March 13, 2019 Share Posted March 13, 2019 It's still not obvious if the rocket reusability makes any economic sense for such small rockets and such small launch count. The reusability will definitely make sense for ~1000 t payload rockets, or for a Daily Falcon schedule. Also it makes sense for a Corporative Launch System, when you company has a rocket in the garage, and uses it once per month, landing on the backyard. But these conditions anyway require space nukes as a current normality. Otherwise it's nothing to lift even if the rocket is cheap. And unlikely this will get possible until 2050s. So, that's no need to cosplay Space-X. Quote Link to comment Share on other sites More sharing options...

They see only two billionaires toying around with reusability while every “credible” space program at best pays lip service to the idea (Vulcan’s engines, the proposed Ariane engine flyback...), and thus they decide (buttressed by skepticisim dating back to the Buran era) that reusability is a “fancy marketing trick”.

At which point @sh1pman punches the screen. Did Soviet engineers who designed Energia-2 concepts care about marketing? I really don’t get this “marketing trick” mentality. “Hey, we’re saving a ton of money for ourselves by landing our stages!”. As a potential customer, I wouldn’t care. I’d only want my satellite in space. The only potential benefit of reuse is for the launch provider. And if there’s a competition, reuse allows to lower the prices and be more competitive. If Roscosmos is a for-profit agency, with budget problems at that, it makes all the sense for them to explore the reuse possibility. If they’re waiting for someone else to prove that it works, then that someone will also leave Roscosmos without commercial payloads, which is kinda already happening.

The average Musk basher will argue, foaming at the mouth, that they can’t possibly be saving money because muh refurbishment costs and muh lost payload fraction. Never really tried bringing up Soviet reusable designs with them (which would have been myself, were I arguing out of nationalism rather than general jadedness). Could turn out interesting. 3 hours ago, sh1pman said: If they’re waiting for someone else to prove that it works Technically they are: they’re waiting for NIIMash and all of the other learned and respectable people that are part of Roscosmos. No-one else’s claims (or deeds) will do - the solipsism of a conspirologist. Naturally, they’ll keep waiting for a while.

Falcon 9 shows that reuse works very well. No SpaceX has no reasons to offer launches as cost efficient rates just much lower than others. Fairly obvious to me that inside of 20 years you do second stage recovery or you are not an player in the launch marked. Not saying that national space agencies are pointless, only that they just serve an military / intelligence role only. Reuse is pretty obviously better as long as refurbishment don't cost more than an new stage ala shuttle. Note that for military purposes an cheaper cruise missile might win over an reusable drones as you can do an larger first strike and you expect high losses anyway.

tater Posted March 14, 2019 Author Share Posted March 14, 2019 (edited) Regarding reuse, SpaceX has zero incentive to reduce cost to the customer much, that is not an indicator at all of the efficacy of reuse. If a typical launch costs X, as long as they are very slightly below X, they win, and pocket the difference. We can say reuse makes sense for the simple reason that they continue to do it. If it didn’t make financial sense, they’d abandon it, they are a business, not a charity. Edited March 14, 2019 by tater Quote Link to comment Share on other sites More sharing options...

I honestly don’t think Roscosmos understand the concept. If Musk were motivated by profit, he’d be embezzling from his own business... wait, can a person even own their business yet be more than a shopkeeper? Does not compute. While the more business-minded state companies attract the more capitalist-minded individuals with their stability and relative generosity, even there politics, whether international or interdepartmental, and often personal enrichment, matter far more than profits of the overall organization. Now imagine how that works in an organization staffed largely with economic illiterates born under socialism and taught that evil capitalists aren’t in it for the profit but UNLIMITED POWER... Suffice it to say, the world looks rather different to them. Quote Link to comment Share on other sites More sharing options...

And even if they did undercut the market price, Roscosmos would just accuse him of selling at a loss thanks to Pentagon subsidies on his natsec launches. As they already do. I find it difficult to believe that the cost to re-launch a Falcon 9 2-4 times is cheaper than rebuilding the booster each time. There have been a few claims that whatever the entire reuse program cost, it hasn't yet (and possibly not during Falcon 9's existence) won't be recouped by flying block 5 3-4 times each. Musk's response would be that his goal remains to colonize Mars, and that quibbling over whether or not he developed the tech needed to reuse a rocket "for free, or at some slight cost" is entirely pointless. He now knows how to reuse rockets, and that is absolutely necessary for high volume space travel. Typically this cost analysis makes a ton of sense in government programs that don't allow companies to use them for their own R&D. You have to justify each program entirely on its own without regards to any other program (doing otherwise typically involves fraud). It might have influenced some NASA types, but I'm sure investors just laughed and saw things the same way Musk would. Quote Link to comment Share on other sites More sharing options...

Given a landing on Venus, a crash is just the quickest way to arrive at the final fate of the craft. It's not like it would be in any better shape a year or so after a soft landing.
