  The trip to mars takes about 6 months (~180 days). Every single record in the table you linked is longer than that.

    Ah, I guess I was assuming round-trip. Article mentioned 3 years as the likely shortest round-trip. I suppose if we are talking about a one-way death trip then yea. Maybe some people will do that initially, but long-term you'd have to think our goal of reaching Mars would include being able to return.
