On November 17, SpaceX CEO announced that he completed the efforts to “upgrade [the currently expendable second stage on Falcon 9 rockets] for reuse,” and instead “accelerate” the development of a completely reusable two-part rocket known as “BFR”.

The new rocket’s reusable first stage will now be known as the “Super Heavy” Booster and rocket that is on top of what comes to transport cargo and passengers to the moon, Mars, two days later, Musk explained that BFR will not actually be called “BFR” anymore, but would prefer to have two separate names for its two separate parts. The new rocket’s reusable first stage will come hereafter to be known as the “Super Heavy” booster, and the rocket that sits on top of it, which will transport goods and passengers to the moon, Mars and elsewhere, will be called “Starship.”

Rapidly forward another two weeks, and we got our next clue what might be the most important task of Super Heavy-Starship pairing will be asked to do: Insert dozens of small satellites in circulation in

The United Launch Alliance Delta IV Heavy Lift Vehicle would need to carry out 170 missions (more missions than ULA has performed throughout its lifetime) to lift so much mumps in circulation.

Fortunately, SpaceX not limited to Delta IV’s lifting capacity. Enhanced by Super Heavy, SpaceX’s own Starship will be able to lift 150 tons to low ground. And that means SpaceX, when Su per Heavy and Starship are active, will be able to perform the job in just 32 missions, or about 18 months of work at current launch rates.

So, how does SpaceX space launch costs?

No replacement costs cost the cost of each Super Heavy -Starship launch will basically be the cost of fuel consumed to start and land the rocket (plus renovation costs, employee wages and other costs).

I do not really know the answer.
