As has been discovered before with samples from Mars, not everything that is "water" in terms of Martian findings is able to sustain life.

So, is this new water discovery
good water, or
bad water for life support & sustainability?
They failed to mention that, & just got caught up that "water" was discovered.
Looks like some further info & testing is needed, but this certainly is a breakthrough!
