Just got to thinking about some of the problems that may have to be addressed if & when we ever try to visit Titan in person.

The first thing that comes to mind is what might happen if some Titanian air gets inside an oxygen-rich manned spacecraft, say from minor airlock residue. I imagine that the explosive potential of some of the trace gasses is pretty high, and there's probably also a significant risk of poisonous compounds as well. So, here are some tenative requirements:

1. REALLY efficient air-scavenging airlocks.
2. Surface suits that can't trap external gasses in creases, folds, etc.
3. Spark-proof electrical/electronic everything.
4. Smoking is strictly forbidden (with apologies to the entire 1950s SF movie genre!) rolleyes.gif

Gotta be more...any ideas?

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
