because mars missions are expensive things that require a lot of PR to
keep funded. Putting attractive, fit, large men and women in front of
the camera goes a long way toward justifying the budgeting. If your
mission was manned by Vern Troyer and company, it would be the laughing
stock of Washington. (nothing against Vern, I like the guy, but you get
my point).
