It has been a six sigma day here - in the sense of "nowhere near normal." I'll post about it tomorrow, but for now, a graphic I found and keep handy.
If Google is being nice, this should download as a 1200x1575 pixel graphic but still be legible if you look at it on your monitor. As you can see in the bottom margin, it's from Visual Capitalist (dot com!) and it looks at the cost per kilogram to orbit through the history of modern space programs. You'll notice the cost stayed in what appears to be a narrow range from 1960 until around 2010. Now part of the reason for that looking narrow is that they used a logarithmic scale, which visually compresses it. You'll note, for instance that Saturn V is under the $6,400/kg line while the Shuttle is above the $51,200 line. $51,200 is eight times $6400, but the log scale doesn't make the Shuttle look eight times more expensive.
This is a topic that I know I've written about before, and recently been joined by Borepatch.
The interesting part of the graphic, of course, is the right side which
emphasizes the differences SpaceX and their reusability have made. That
estimate for Starship of $200/kg (around $90/lb) is much smaller
compared to the others on the chart because of that log scale again.
The cost for the first Falcon 1 was in the vicinity of $12,800/kg to
orbit. In the same neighborhood as Delta Heavy. The planning cost for Starship of $200/kg is 1/64 of
