Earlier quoted context omitted.
Starlink? But these companies (well, at least SpaceX) have their focus on making orbit cheap and sustainable, and pushing towards Mars colonization and asteroid mining. Those are engineering and logistics problems more than science problems, but I think they're very important.
Those are all ways to squander the Earth's limited resources while sounding forward thinking. Colonizing Mars will likely never happen, there is simply no upside: huge challenges, with no interesting resources. The Earth has plenty of space, we're limited by resources, and there are no interesting resources on Mars. I wouldn't be surprised to find out that we'll have a colony outside the solar system before a colony…
There are new discoveries on Earth even today, after hundreds of thousands year of mankind history. What make you think we have known all we need to know about Mars?
> I wouldn't be surprised to find out that we'll have a colony outside the solar system before a colony on Mars.
Mars is a 8 month journey. Alpha Centauri, the nearest star, is a 296,000 year journey using the current propulsion technology. We'll have colonized every single colonizable planets in the Solar System before then.
> it's much more interesting from a profit perspective than a future of humanity perspective.
Future of humanity depends on advance in science. Space exploration has always been a major force that drives science forward, asteroid mining included. So many examples to list, but just to pick one:
