Spaceship (estimate)

An important detail is missing: whose estimate?

[–] soumerd_retardataire@lemmy.world 4 points 1 month ago* (last edited 1 month ago) (1 children)

The chart seems to have emerged from an apparently famous report(, p.13, discussed there), whose taking its source from the Center for Strategic and International Studies, an american think tank.

As for the estimated cost of Starship, a cost inferior to $300/kg(, sometimes below $100/kg) seems confirmed all over the internet after a quick research, although the prices are varying, with many articles(, e.g.,) speaking about an aim below 10$/kg.
However, interestingly enough, the only contradiction i found came from wikipedia, since a capacity of 100.000-150.000kg for a current launch cost of $100.000.000 would imply a cost of 666-1000$ per kg.

I've probably made mistakes while checking all of this, so feel free to dive deeper in order to explain the differences between SpaceX's estimates and the wikipedia page.

I love such curve-fitting techniques. By 2025 we can launch 1t into space for a few cents, if we follow the purple line.

[–] Fermion@feddit.nl 2 points 1 month ago

It's also absurd that the fit line dives down to be cheaper and earlier than an optimistic projection that will likely move further to the top right as time progresses. That's a chart with an agenda, not an analytical regression.

Yeah, and the curve would be even worse if the y-axis was linear b.t.w. 🤷

[–] Fermion@feddit.nl 2 points 1 month ago

I think this actually is a linear regression plotted on a log y graph.

Which a linear regression is a bad choice for something that must be asymptotic at best.

This is somewhat deceiving, as the drop only looks steep because of a single data point (falcon heavy) and an estimate.

[–] sircac@lemmy.world 1 points 1 month ago

I cannot agree more with this comment, the bias is so evident that is in the brink of being plain propaganda

[–] henfredemars@infosec.pub 6 points 1 month ago

I really miss the space shuttle. That was really cool, and I don’t think we’ve built a vehicle that quite compares.

[–] Toto@lemmy.world 6 points 1 month ago

Would be interesting if it was adjusted for inflation

[–] lemmyman@lemmy.world 4 points 1 month ago (1 children)

How is spaceflight weighted in the CPI?

[–] soumerd_retardataire@lemmy.world -3 points 1 month ago* (last edited 1 month ago)

lol, kinda amazing that it'll become pertinent to ask this for the next generations(, probably not before the construction of a space elevator though).
We're only little mammals and now are leaving the planet, as far as we know we'd be the first earthlings to do so, what a step.

[–] stupidcasey@lemmy.world 1 points 1 month ago

Wow, only $200 a kg? Ima ship a 12 pack of Doritos locos tacos to space that ought to get the Aliens attention.
