There was an estimate on the life span of the ISS and think it was like 25 years, can't remember. I think in the back rooms of NASA there is a push to establish a permanent base on the moon before that time comes, I think the funding is available. Due of the lack of vehicles to get us to the moon who know when that day will occur. I probably won't see a trip to Mars but maybe a new moon base before I check out permanently. I have always said I was born 100 years to soon. On a side note I don't buy into the notion that NASA has an established base on the moon already. (wink-wink)
