Thanks ezgo & Adam. To clarify this a bit: He3 might be a good solution but I was thinking more like liquid hydrogen, so its nuclear thermal propulsion. It's quite old concept and therefore should be reliable and probably affordable; and also tested by NASA, as far as I know.
If the propellant is not enough (can't calulate it since I'm not a ... ehhhh... well... a rocket scientist) there is possibility to launch some beforehand to Mars orbit (1.stage). Also added some radiators.
Still scifi but as plausible as I can get :)

Regarding the launch escape system, I would prefer a "pusher" LAS using integral engines instead of a "tractor" LAS that is jettisoned in flight because the "pusher" LAS, being integrated into the spacecraft, allows for escape during the entire orbital ascent phase. That's why Boeing's CST-100 and SpaceX's Dragon 2 space capsules use "pusher" LAS. For your spaceplane's LAS, I suggest you take a look at the Sierra Nevada Corporation Dream Chaser lifting-body spaceplane.

I don't know which is more plausible, but certainly I like Your Spacebucket drawings.
