I’m afraid I continue the tradition in astronomical circles of giving every experiment a name based on a ridiculous acronym.
NOVEX stands for NarrOw field of View EXperiment…. ;-))
The smaller FOV’s yield meteors that zip through but if you’re lucky enough to catch one at it’s end you can see some remarkable effects.
As for the iron meteors, they behave the way they do because of the very specific thermo-mechanical properties of the iron/nickel (as you would expect) but you’re correct it cannot be extrapolated the other way as the interface between the meteoroid and the atmosphere has so many variables in terms of both composition and mechanics.
