That was really interesting.
But a lot of assumptions are made that I don’t understand, e.g. how can we be so confident of each asteroid’s composition?
Much better than a rocket launch vid though.

Mostly ground based IR spectography, and more recently planetary radar (and even more recently sending probes to study them up close).
There are many ways to combine elements to create the same looking spike on a spectrograph, though I guess some spikes are less vague than others.
