Table 3: Estimated deposit size in tons—pessimistic scenario. the predictions presented in the report [66] can be used. The authors of this report estimated that the price of water for fuel production in space if it were imported from Earth would be 10 M$/ton, and if water were extracted from ice on the Moon and brought to low Earth orbit (LEO) it would be 0.5 M$/ton. We can, therefore, make a reasonable assumption that the price of water from lunar water ice will be $500/kg.  
It is much more difficult to estimate the price of CO\({}_{2}\). This raw material will be used to produce methane for the fuel of the SpaceX Starship vehicle. SpaceX's contract with NASA to deliver astronauts to the lunar surface and take them back to a lunar orbital base under the Artemis program is USD 2.8 billion. The fuel mass of fully filled Starship tanks is 1200 tons, part of which is liquid methane and part is liquid oxygen. Starship takes off from Earth with only partially filled tanks to reduce launch mass--it is carried to low Earth orbit (LEO) mainly by the Super Heavy first stage, which returns to Earth. In order for the Starship vehicle to continue its flight to the Moon or Mars, it will need to be refueled in orbit. The payload capacity of a Starship launched from Earth is 100 tons, which means that it would take 12 Starship vehicles acting as tankers to refuel one Starship vehicle in orbit as it travels to the Moon or Mars. [PERSON] announced that the cost of the Starship operation into Low Earth Orbit (LEO) will be no higher than USD 10 million, which means that refueling Starship in LEO will cost 120 M$, which gives a theoretical fuel cost of 100 $/kg without distinction, whether it is liquid methane or liquid oxygen. Refueling in orbit will not be without fuel losses, as liquid methane and liquid oxygen will evaporate, hence it can be assumed that the fuel cost may be as high as 200 $/kg, which allows for taking into account fuel losses and the costs associated with the production and storage of fuel in space. Of course, the price of refueling on the Moon should be lower than on LEO, but 200 $/kg can be considered the upper limit of the price for fuel, including CO\({}_{2}\) raw material, acceptable to SpaceX. However, this is a highly speculative price, as SpaceX's plans for obtaining methane for Earth-Moon travel are not known yet, and it is possible that SpaceX has already solved this problem in a different way.
