[MCU] What's space exploration like at the time of Infinity War? Is man on Mars yet or what? Colony on the moon? Rovers on Titan? Subs in Europe?

It’s only been something like ~~10 years~~ 5 years or so since the general public learned that aliens even existed. That’s not really a whole lot of time to set up manned missions to anywhere, even if there was interest. 

And there wasn’t, since that general first contact took the form of a violent invasion — not from space, but through the conduit of a space-time portal generated on Earth, through a stolen cosmic artifact. 

The prudent first measures to be taken in the aftermath of such a contact would be to shore up your defenses and attempt to either make sure it won’t happen again or be ready when it does. That would take the form of developing advanced defensive technology (Stark’s “suit of armor around the world”), securing and containing known cosmic artifacts to prevent possible ingress through them, and trying to account for and control the enhanced human assets that proved so crucial to fighting off the first invasion. All of which were exactly what the world as a whole has been up to since New York. 

Space exploration is going to be somewhat lower on the priority list here.
