This is like asking about how long a cubic meter of raw ice situated in
1 AU space would last, such as if deployed at the Earth-moon L1 or even
Earth L1.  Lo and behold, it seems there is no actual objective science
or even textbook simulations to draw upon, and none planned.

Why simulate?

You know the reflectivity of ice, so you know how much energy it will
absorb from the Sun at this distance, and you know how much energy it
takes to melt ice.  You know the vapor pressure of water once it's
reached thermal equilibrium at this distance from the sun, and even if
you can't calculate its temperature you can "guestimate" it at the
average temperature of the planet you inhabit.  (Maybe.)

That will give you an answer which will be quite good enough until such
time as you can afford to transport a ton of ice to Earth-Luna L1.

Why not try it?  It doesn't cost anything.

That's pretty gosh darn dumb, even for yourself.

Where's the objective evidence or proof-positive about a given volume
of ice at 1 AU, as coexisting for X amount of time?

Why is mainstream science so deathly afraid of ice in space, or even
the release of water in space (say at the Earth-moon L1)?
