Half way there you start decelerating. You can start later in the trip but that requires more fuel.

Because the more fuel you carry the less room you have for a payload.

What are you talking about this is total BS. You only slow down to enter orbit.

The energetically optimal planetary transit requires you to take a path something around the lines of pic related. This is taken from KSP (a video game) so read earth where it says "kirbin" and mars whrere it says "Duna".

if we had capacity to go faster it would directly imply that we had capacity to use our brains and realize that such domes could be built on earth. If they couldn't withstand nuclear winter, how would they even work on mars?
