I would use a version of MX missile for Ascent Vehicle. Its solid fuel = dependable.pic.twitter.com/Mxoyyh1HQL
Half the planning for Mars starts with how much Ascent Vehicle you need to get crew back to orbit.
Then you work backwards from there. How much Lander do you need to get Ascent Vehicle to surface.
Since the gravity of mars is 0.38 of earth won't we need approx 0.38 the fuel we use to reach earth orbit.
That's a lot of fuel to land on the surface and it needs to be solid fuel. Crews can't afford complexity of
liquid engines or even mining atmosphere for liquid fuel. How many Kennedy launches were stopped for mechanical
problems? Crew won't be able to make repairs nor will they have time because of launch windows. = solid fuel
