Er...
Don't ask....
No problem. Esperimental, I presume.
You do realize you can borrow one of the Gas-Cooled Nuclear Reactor/Rocket Engines for a short trip, provided you have qualified as a pilot in it. (That requires a training session similar to familiarizing yourself with a new video game.)
I'm anticipating that after we arrive in Mars orbit, a small contingent will want to head further out to the asteroids to look around. We'll need a very careful flight profile listed for that, because of differential orbital speeds, but a proper plan will be authorized.
I'm assuming that not everyone will want to go down to the surface of Mars, and many will be content to remain in orbit above it.
