2018: mars flyby for two

Can do still exists.

Michael O nails it...

The leap in knowledge of space travel in general would be worth it, to say nothing of the sweeping riddance of any doubts that it could be done. You “touch” Mars in this fashion, and you’d have a “double dare” for someone to land, and land to stay.

Just five years away is certainly doable. I hope the two survive.
