Like it says in that mouthful of a title. Unfortunately, I’m both too tired and have _way_ too little faith in my math _or_ Orbiter 2010 skills to figure out a halfway correct answer.

Either minimum Delta-V, or the minimum required to keep transit time under about a year, if possible.

So…can anyone help me out? [del]There’s a potentially lucrative share of off-planet pharmaceuticals at stak[/del] it’s a matter of astronavigation I’m finding quite fascinating.
