Considering a simple Hohmann transfer, does it take less Delta-v and propellant to go to Mars than to the Moon

Not for a landing. Moon, 1730 m/s. Mars requires twice as much, 3800 m/s. enter image description here

    $\begingroup$ Mars does allow aerobraking and chutelanding, so by the delta-V map you've displayed, for a sufficiently light and risky mission, you can put an object on surface of Mars for at total of about 13.7km/s during a Hohmann transfer window, vs 15.1 km/s for a propulsive Moonlanding. $\endgroup$

    $\begingroup$ The one thing that is bugging me about this map: I'd expect the grey link between LEO and Moon Intercept (3260 m/s on the map) to be pretty close in value, but less than the blue link between LEO and Earth Intercept (3210 m/s.on map) under coplanar/circular orbit simplifications. I wonder if the creator priced in a plane change to the Moon intercept burn. $\endgroup$
