I suspect there are substantial numbers of us in our 70's+ who would volunteer. Why not go out having made an amazing contribution?

I'd be surprised if there's a single person alive who would volunteer for a suicide mission to a miserable cold dark planet and could travel there for nine months in a tin can through a harsh radiation/muscle atrophy/psychological environment and arrive in any condition to conduct useful scientific work.
