Delta-V and the curse of logistics
#5
Quote:
In terms of delta-v, Earth-orbit to Mars-orbit is closer than Earth Surface to Earth orbit, unless my memory fails me. Any difference that you may see in the relative logistics is a product of the animated canon's poor attention to detail. ^_^
That DV rule-of-thumb only applies for a Hohmann transfer with one (rather broad) launch window every 780 days (one Mars year), though, with a transit time measured in months. Not impossible, with the example of naval transit times during the Napoleonic era, but definitely problematical -- at minimum, logistical response from Earth will lag nearly two years behind current events on Mars. The alternative is to introduce constant-accel drives that have the side effect of making weakly relatavistic bombardment of planetary targets cheap and easy....
And there's the question of whether the logistics come from Cislunar space (factories on Luna, say), or all the way from Earth *surface*, in which case you've got *double* the DV requirement.

Anyway, Mars will not be the entire setting of the 'series'.
Hm! I wonder how far-ranging the story will become. Honestly, I've always had to make an effort to swallow the whole "mobile suits in spaaace!!!" thing, but I'll turn a blind eye to almost anything if the story is fun enough.
