Dredging up approximately 385 tons of lunar dust...
And In addition to recording the collision
The Sheperding, Spacecraft will fly through
The regolith plume thrown up by the collision...

Sheperding Spacecraft will utilize it's specialized sensors
To look for water's telltale chemical signature
Within' the larger debris plume created by the Centaur
Possibly in the form of ice, hydrocarbons or hydrated materials...

[sigh]

Those who live will have the best opportunity because of the sky
The best opportunity because of the sky will still be dark.
Those living east of the Mississippi will still be able to see the moon
But they'll also have...
Twilight...
