@Erdayastronaut @Blamblas @latimes @SpaceX @blueorigin Exactly. Mars propellant production will combine atmospheric CO2 & water (ice) to make CH4 (methane) & O2. Will do same on Earth long-term. Short-term, each Falcon flight uses roughly same fuel mass as a 747 flight. Falcon is ~71% oxygen & Starship is ~78%, so mostly not fuel.
