Your assertion about getting to Mars with less propellant is super interesting. Can you provide a source for me?

- hoorayimhelping 9y agofewer than twenty five seconds of googling: https://en.wikipedia.org/wiki/Delta-v_budget https://en.wikipedia.org/wiki/Delta-v_budget From LEO to the surface of the moon is 5.9 km/s From LEO to the surface of Mars is 4.1 km/s
- dwringer 9y agoUnless I'm misreading something, both the text and graphic of that page seem to indicate it's 4.1km/s from low Mars orbit to the surface of Mars. I can't find anywhere saying it's 4.1 from LEO.
- Kubuxu 9y agoI get 2.5+0.7+0.6=3.8 to get into Mars Transfer from LEO. If we were to execute perfect aerobraking, the rest would be free. It for sure wouldn't be perfect so some fuel will be needed but not that much.
