When do you think we're going to set foot on Mars? I personally believe it should be done at some point before 2040, but probably not sooner than 2030. Why? I think quite a bit of people believe it'll be done before 2030, but such huge projects evolve so slowly... There's still a ton of things to figure out before we're ready to send astronauts to Mars. It's going to be humanity's greatest journey since we reached the moon. That's huge. What's your opinion?
