The discussion of using colony ships as emergent troop transports has led me to think about the current mechanism for colonist transport. Imagine saying good bye to your family, going to the SolTrak terminal, stripping down, going through the showers (assembly line process), putting on a grey jumpsuit, entering your coffin (destined for Titan), going to sleep (deep freeze), being loaded on the ship, one day later ship leaves Earth, next day arrives at Mars, coffin unloaded at local SolTrak terminal, defrost process and you wake up with the worst cold of your life (sneeze), you get back in line, strip down again, new shower (hot water heaters malfunctioning), new jumpsuit, look out a window and wonder at the redness of Titan, and read the "Welcome to Mars" sign, Anger, Disgust, and finally, submission as you are escorted to your new fully furnished apartment. You are given your new provincial citizen number (non-voting status) and a map from your apartment to your work site (oh, by the way your career path has been changed from administrative assistant to construction worker putting up more apartments at the foot of Mons Olympus). This would have never happened if you had never had to go through that damned cold-causing deep freeze treatment (long term side effects still under investigation). Two weeks later word arrives that a new class of colony ship is to be built that will ship colonists without the cryogenic freezing. By the time it is completed you are firmly entrenched into the Martian society and due to a lack of workers all requests to move to Titan are denied. You walk up to an airlock, equalize pressure, enter the airlock, equalize pressure with the outside, sit down to await your death, only to realize as the outside door slides open that the long term terraforming project has produced the minimal amount of oxygen to keep a human alive. You fail again.
Long story short, how about changing the mechanism for colony transport from cryogenic freezing to something more akin to the current cruise liners?
Just a thought.
