If there are polar ice caps, obviously there is water. If life ever existed on Mars, surely some remnant remains to this day. Life or not, water is what you need if you want to set up a base on another planet…
But I think one answer is ‘natural resources’, and corporations will be the most anxious to really get moving on missions to Mars.
Hopefully nucleobases but I think more rocks and sand and other shit.
NASA puts the findings of “other shit” at .2g per Kg collected. Imma win dis.
All the pens I’ve lost over the years.
Note to NASA: PLEASE do not awaken the “old ones”!
If NASA were smart, they’d claim to have found rare metals and gold. That way, they could just book flights to Mars and back on commercial flights by this time next year.
It’s been.said before (and I believe it) - if there were solid pure gold bars on the moon, stacked ready for collection, it would not be cost effective to go and collect them. I imagine this is even more the case for Mars.
Socks lost in the dryer.
But there are plenty of folks who would buy million dollar tickets. 
..and to the cats back they will find buttered toast and the whole shabang was attached to the rover to slow the decent.
You mean . . .
Curiosity killed the cat.
Thank you, thank you, thank you for making my day!!

:rolleyes:
The rover will discover a Starbucks. With menus printed in an unknown language.
“large” for small, “largo” (or whatever the hell it is) and “humongous” are an unknown language.
Tragically, Curiosity is too large to fit through the doors, and will never be able to place an order.
Pfui.
It has a mast mounted rock burning laser.
It took that long?! Yeesh, every must have been having a busy day.
I vote it finds a second, steampunk, rover.
A rock with ERB scratched on it.
