Time frame

Hi,

I would like to hear your guessings about when the tech is ready and
society get ready to achieve the goals of deploying space
settlements.

Yes, I know nothing is certain about the future. However, a little
guessing with the right arguments I believe is worth ten cents.

This are the goals, you put the dates:

(1) The first full functional space hotel.
(2) Eficient way to send load to orbit already full functional
(either scramjets, laser propulsion or space elevators)
(3) Moon base build with mass driver
(4) Building of an lagrangian Space settlement.
(5) asteroid minning.
(6) Space settlement around Mars
(7) Space settlement in Saturn
(8) Space settlement in Alpha centaury.

Please, tell me why you believe the dates you guess.

Regards,

Omar Vega
