actually I was a little high. It’s cost per launch was $1.5B in 2011 dollars ($193B over 133 flights). It’s cargo capacity was only about 40,000 lbs, so around $37,000 per lb. The truth was it’s stack had massive launch capacity, over 200,000 lbs. but it was almost all used up by lifting that space plane. A higher launch rate was never really possible. The solid boosters weren’t reusable without a huge amount of work, and the shuttles needed lots of maintainance between flights. The BFR is designed with theses lessons in mind. It’s fully reusable and it’s seconf stage should be way more efficient. But we will have see how much maintenance it will require between flights.
