Sometimes I dream of working on another really big project like bringing water from Europa to Mars and the moon, and bringing hydrocarbon from Titan to Mars and the moon and then building permanent towns both places. Funny thing, this is for the future although it could have been started 30 years ago.
Yup, some 60 years from the Wright brothers first flight to a moon landing and next to nothing (manned) in the 40 years since.
