In my novel, Shifting Mars’ Sands, set 200+ years in the future, I rely on the ability of people traveling from Earth to Mars in 30-40 days, depending on Earth’s relative position to Mars. I didn’t want it to be too long, so no one would want to do it, but not too short, so anyone could take a long weekend trip, either.
For the purposes of my novel, I needed Mars to develop a cultural split from Earth, and I figured that time frame would enable such a split.
Now, I see an article where a rocket engine is being developed to allow travel to Mars in 39 days. My first reaction was one of justification–it can happen. I’m left, however, with the feeling that 200+ years from now, 39 days to Mars’ll seem ridiculously long.
I’m interested in many things, from Mars to space travel, music to books, movies to creating my own stories. My sci-fi novel, The Music of Mars, is available now.
