I’m giving a talk on the economics of spaceflight on Friday in Omaha. Does anyone have a chart showing the cost per flight as a function of flight rate for both expendables and reusables? Doesn’t need to have citable numbers in it, just looking for something conceptual.

…will only go to the moon if they’re selected by NASA.
They may have no current plans to send the spacers into space, but that could change with the advent of Starship.

Sorry about the missing link. I’m surprised that no one mentioned it sooner.
The Crew Dragon Mission
There was a little more damage than expected.

Starlink
It’s getting early rave reviews.
This Looks Like A Blast
Combining hypersonics with directed-energy for drag reduction?

Commercial Space Habitats
Blue Origin is considering getting into the game.

I do think that Venus gets far too little attention. Maybe this will spur more action in that regard.

This is a six-year-old article, but it’s relevant. Seeing what it looks like at the one-bar level of the atmosphere should be a high priority.
