KG5, you're right. We "didn't have the technology" When Kennedy proclaimed that we were going to the frakkin' moon in less than a decade. We damn sure developed it though!
Unfortunately, the first US President to proclaim a goal of putting a man on Mars by 2030 wasn't backed by the rest of the government. That bold statement by George Herbert Walker Bush just fell by the wayside.
It would be interesting to see where we'd be now if there had been follow through on it at that time. So many technlogies we take for granted now came from that initial push to Luna 40 years ago.
Oh well, maybe the Bigelow people can rub some noses on an operational Transhab based facility in the not too distant future.
