Thanks for your review, too, johnr. That gives me more reason to watch;^)

Saw the first episode and was very happy with the result. By 2033, I will probably be long gone but sure wish I could stick around to make the trip. I think the film adaptation of Andy Weirs' book, "The Martian", has certainly given a little more impetus for pressing ahead at a faster rate. Kudos to NatGeo for a well done series( so far).
