Space Travel?
From tourism to Mars and beyond in the next one hundred years, colonies and the Internet will be superseded by new things and we might begin the mission to our nearest star in the hope of making contact with other aliens!
Will we ever get to a large Space ship is a unknown, since we do not as yet fully know how we might get through the Kuiper belt and how does gravity act outside our own Solar system?
But we will establish colonies on Mars, the Moon and some other planets, while others will be for research and science perhaps further out!
Without a new shuttle being developed, we will be limited since Space-X is not advanced as it is claimed to be and it all depends on how much money can be invested now to keep the International Space Station operating and getting updated, if not rebuilt in Space?
