I tried "trench(es)" and "valley(s)" first.

I also tried "trench." I know it's usually meant in the man-made sense, but I always think of the Marianas Trench, which comes to mind when conjuring the Martian trenches...or canyons.

I tried a lot of things, including canals, since that's something people speculated they were. Don't know why I never got round to canyon or gorge though

My first idea was "chasm", however that came to my mind.

"Valley" wouldn't work either but then I got it with "canyon".

The english language seems to have way to many words for this and as a non-native english speaker it's sometimes difficult to see the subtle - or sometimes even not-so-subtle - distinctions between them.

Sometimes it pays to be old enough to have seen the space programs from 1957 to present and witnessed all the achievements.

Eeesh, only got 8. Had higher hopes for this one, considering it's my mother-in-law's home planet.

I like the length of Martian days better than Earth days. My natural sleep schedule on Earth seems to be on a roughly 25 hour cycle which causes problems.

I really wanted one of the rovers to be named Red Rover ;)

Also, too Mars-centric. Impossible to know any of these answers if you like in the UK.

Sure, when we find Dicarbon Monoxide on Mars, we'll do it.

As of Now, No.

What about C3PO?

"C2O" is an extremely rare, extremely reactive molecule that would be a solid, not a gas.
