This Is the Insane Metallic World NASA Wants to Explore Next

"NASA announced the finalists for its next round of planetary explorations.
There were the usual suspects-Venus, Jupiter's asteroids-and, then,
there was this: An asteroid, composed almost entirely of (possibly magnetic)
metal, with a crust literally beaten away by interstellar collisions, named
Psyche.
Pardon?
If you haven't heard much about Psyche yet, there's a good reason: We don't
know very much about it. But the things we do know are, in a word, bizarre-
starting with where it came from.
A Crash Into A Metal World ----"

and
https://en.wikipedia.org/wiki/16_Psyche
"16 Psyche is one of the ten most-massive asteroids in the asteroid belt.
It is over 200 kilometers in diameter and contains a little less than 1% of
the mass of the entire asteroid belt. It is thought to be the exposed iron
core of a protoplanet --- "

I don't know why anybody finds that surprising. Lot of "rocks" out
there are nearly pure nickel-iron.

Ya does a big fly-by, trailing a HUMONGOUS magnet, come back and crash it on the moon. Winds up being the source for ALL THE BUILDINGS we gonna need when we (or the Chinese) go back.

I suspect part of it is the "exposed iron core of a protoplanet" bit -
the info that would provide could be impressive. Of course it's easily
big enough for the old - first melt it, then spin it, blow it up like a
balloon and build a Whacking Big Space Habitat trick, someday... Just
thinking. :)

Meanwhile the reminder of all the nickel-iron asteroids out there and
the fact that it wouldn't actually be all that difficult for a lot of
'em to be magnetic is leading to some of the most hilarious images in my
head right now.

Way too big for that. Honestly, "that trick never works". Spinning any
asteroid of significant size up to "you'll have decent gravity on the
inside surface" levels will disassemble the asteroid. If it WOULD work,
it'd be on relatively small asteroids.

Why do it the hard way? Just build on Hyperion, where half the work
has already been done.
