He wants to go to Mars in it? Will they be relying on autopilot on Mars or like the Eagle landing on Luna will they have a test pilot on hand to take over just in case?
They won't be sending humans until multiple ships have landed on Mars and deployed the solar farms and Sabatier-process equipment to make fuel for the return trip (and run things like air scrubbers and other support infrastructure/plant for manned bases).
Given the delay in comms, those pathfinder cargo ships will have to make a fully automated descent. Humans won't be going until that whole process is nailed down and their support hardware is successfully delivered.
