I swear in my life time we've discovered water in Mars about 8 times now.

I don’t understand any of these comments. Discover has two meanings. Unexpected or within the course of a search. We discover oil and mineral deposits all the time. We don’t usually say “You discovered more lithium? Big deal. Been done before”

While it may not be mind blowing, each source of water discovered makes some kind of Martian base more feasible so it is of interest to some

If new sources of water don’t interest you, that’s fine. But it is still within the definition of discovery

That's because (newsflash) there's water on Mars!

Question is when will someone invest in a mission for something that actually does something with it that is not measuring its existence with remote sensors.

I think the parent is alluding to the fact that this topic keeps being presented to us as news.

There's water here on Earth, too. But we don't keep "discovering" it.
