Ja, this lander gave us exactly this.

Exactly so, and this one was not designed properly.  The water content of
the soil was sufficiently high as to make it clumpy.  Consequently it
wouldn't drop down into the ovens until the moisture had sublimated, leading
the analysts to the incorrect conclusion that the soil was dry.

I confess that the water in the form of ice chunks took me by surprise.  I
am having a hard time imagining how it got in that form and stayed there
this whole time.  Why would not it form hydrates?  Why would it be so pure
as to form white chunks?  What gases are trapped within to make it white?
CO2?  Why were the chunks of ice that size?

That is a threat on which I wouldn't spend a minute of worry, not a second.
Evidently rogue black holes are exceedingly rare; otherwise the planetary
orbits would be more eccentric than they are.  Apparently we haven't had a
black hole visit in the past several billion years at least.  No need to
postulate an exotic threat: the risk of an ordinary rock hitting the planet
and triggering a nuclear war is thousands of times higher, ja?
