Lettuce not forget Raptor runs on Oxygen and Methane. Both of which might be produced on Mars.

- fastball 6y agoI mean we know for a fact that there is already (in small amounts) methane and plenty of CO2 on Mars. Obviously if we find lots of H2O this all becomes even easier as we can just combine the abundant CO2 with the H2O to get loads of CH4 and O2.
- anticensor 6y agoYou mean, by unburning the fuel?
- fastball 6y agoYep, effectively! That is what is great about these fuels (H2 and CH4) vs something like RP-1. First you get hydrogen by electrolyzing water. Then you can go H2 + CO2 → CH4 via the Sabatier process[1]. [1] https://en.wikipedia.org/wiki/Sabatier_reaction https://en.wikipedia.org/wiki/Sabatier_reaction
