         | contains the minerals pyroxene and olivine, Sotheby's says.
         | 
         | And that magma is probably identified by isotopic composition.
         | Similar to how we know that the Moon used to be part of Earth.

       | Makes me wonder if this is a potential funding stream for private

         | If you are a monopoly producer (which seems fair in this
         | context) you would set the price of the rocks where your
         | marginal revenue equals your marginal demand. Loosely, you'd do
         | a market survey to see what price the market would be willing
         | to pay for a mars rock[0], then figure out your cost structure
         | for bringing back one more kilo of rocks. You'd factor in cost
         | to launch a rocket, fuel for the rocket, astronaut salaries,
         | and don't forget terrestrial costs like marketing and
         | distribution! If you did a good enough job at predicting supply
         | and demand, you wouldn't actually care what the price of the
         | product is because you would have claimed all the consumer
         | surplus for yourself :)
         | 
         | To specifically answer the optimal quantity question, the above
         | answer implies that you would keep bringing rocks home until
         | the cost to bring them back is higher than the price you set.
         | To be clear, you could still go out and get more rocks and sell
         | them for less and still make a profit, but you wouldn't
         | maximize your profit with that strategy. Competitive markets
         | nudge behavior towards providing more product for less
         | profit/cost which is why we love competition.
