Re: The simplest idea

Expedition redundancy. More than one identical landing ship, with more than one rover and multiple crews. Each lander designed to take all the crews back in an emergency. Backups.

Multiple systems adds expense, but each individual system can be built with less redundancy and more conventional technologies, which may save money overall.
