Performance vs costs. Heavily selected chart, however.

Value of orbital refueling:

If you just fly BFR to orbit, you'll get 150t to LEO and have no fuel to go anywhere else.

But if you refuel tanks all the way to the top, you can get 150t all the way to Mars.

If tanker has high reuse factor, than the price drops.  LOX and Liquid Methane are very inexpensive.

150 mt to LEO. Then refil to get 150 mt to Mars.

So... how do we pay for this system....

This was a profound breakthrough.  If we can build a system the makes our own products redundant, than all the resources for F9 and FH can be applied to one system.

Some of our customers are conservative, want to see BFR fly several times first.

Will have a stock of F9s and FHs so customers can keep using those if they desire.

We will then move on to BFR and pay for it by contracts for sat launches and servicing the ISS.

The key to paying for all of this is to kill Falcon 9 and Falcon Heavy. Go to one system for everything. Will build a large stock room of "old" rockets and then only build BFR from then onwards.

Cargo version with cargo bay confirmed.  Looks to be unmanned.

have a stock of F9 and dragons, turn resources to building BFR, can do it with sat rev and ISS

For BFR launching sats, we can send 9m diameter objects into orbit.   We could launch a Hubble with a mirror three times larger than Hubble's current mirror.

We can launch multiple sats in one launch.

We can use it to retrieve sats and bring them back -- clean up LEO.

Can also service the Space Station.

"I know it looks a little big compared to the Station.  But Shuttle was big.  It'll work."

Moon. No need for ISRU prop.

MOON:

Lunar surface mission w/ no prop production on the moon.

High elliptic-orbit re-filling.  Than go all the way to the moon and back without refueling on the moon.

That will allow for the creation of Moon Base Alpha.
