The Falcon 9 is $62 million, or $2,719 per kg to LEO. The Falcon Heavy is $2,351 per kg when expendable or $1,411 when reused.
The BFR is supposed to have 2.5x the payload for 8% of the cost: $46 per kilogram. Even fully expendable it's $2,233 per kg. That's INSANE. It's space elevator money:
> [For a space elevator, the cost varies according to the design. Bradley C. Edwards received funding from NIAC from 2001 to 2003 to write a paper,[8] describing a space elevator design. In it he stated that: "The first space elevator would reduce lift costs immediately to $100 per pound" ($220/kg).](https://en.wikipedia.org/wiki/Space_elevator_economics)
If the BFR actually becomes reality it turns a journey to orbit into an airplane ride. A $10,000 airplane ride that will shake your fillings loose, but make no mistake: that completely changes everything about space. It makes putting satellites in orbit around Jupiter as hard as visiting the north pole. Fucking TV hosts will be able to go for a quick jaunt around the moon.
If the BFR happens, we'll have a mars base just because it would be so cheap it's a no-brainer. Building a new ISS would be about as hard as building a new Sealab.
