So I got a question.

What's the role of computers? How much of the calculation are done by people?

I can sorta calculate the distance to Mars and the approximate path but could a properly trained pilot replace the computer?

What is the minimum automasation you need? And what's the best path to get to Mars?

You want to use the Sun's gravity to increase rocket speed as much as you can, and have earth going past the mars and then mars swinging around, I think?
