QuoteUnlike other rocky or icy asteroids, Psyche is made entirely of iron-nickel metal, similar to Earth's core.
How would they know just by looking at it? lol (maybe thats a retarded question but still i'm no scientist lol)
I expect asteroid mining in the next 200 years lol
There are plenty of ways to figures it out.
Like for example analyzing the Wavelength of the light.
Each element absorb and reflects / refracts a certain amount of energy.
You just have to figure what wavelength correspond to what element
Then with the addition of Electromagnetic scans, planet's mass data and a bazillion of other things you can refine more and more each composition to decipher the very layers of every planet
But like all science, it's a matter of patience (I can vouch, I do science on DEdit lol).
