@321boom(View Post) Exploring/Colonizing space at this time, and into the foreseeable future, makes no economic sense.
That said, space is largely unknown and mostly unexplored. Given the natural curiosity of humans; we should all be driving, every single one of us, to explore what's out there. Be it to explore what's under your bed, or to explore what's under the ice sheets of Europa. It makes no sense financially to explore space but personally I think failing to explore, to be curious, is failing to be human.
Colonizing space is going to be a byproduct of exploration, so I see both as essentially the same thing.
@code1949(View Post) They would probably be robotic probes for the next 50 years. But power: Nuclear Plasma, Methane and/or Solar (Hybrid rockets lol). We would get to Mars with plasma power in 1 month. Will normal rockets it would take years. So it's easy to survive trips to Mars, Jupiter and Saturn by the end of the century. But further out we have problems. It would take 20 years to get to Uranus.
EDIT: OMFG I checked the results, carbon tax has a lot of "Strongly Yes" votes.
