I doubt we ever will. But if we do it’ll be at 50 years out. The country I would expect to do it is the US. I’m American, and believe me, neither party is pushing space exploration. Politically, no one’s giving money to it. I mean seriously even I, as a Texan, would be salty if they manned a mission to Mars, but still haven’t replaced Flint, Michigan’s water pipes.

China may do it, but they seem a lot mor interested in spreading their control. I don’t think Mars is on their radar.

The EU? I’m not seeing it, but they might have funding for it. Again, it doesn’t seem like a priority.

Russia? Yeah right.

Maybe, just maybe India or an India collaboration with the US. They definitely have the brain power. Heck, they’re supplying the US with engineers. But they might be at war with China and or Pakistan before getting a project like that going.

Edit: It’s like Neil DeGrasse Tyson said, (heavily paraphrased) “Countries aren’t placing space exploration as a priority; they’re not competing like the US and USSR did in the 60s”.
