NMM 3177 is a barred olivine (BO-type) micrometeorite measuring approximately 0.3 mm. This beautiful gem features a large nickel-iron bead surrounded by a sulfide rim. The presence of the mostly intact sulfide indicates a low terrestrial age, meaning this little rock is fresh from space.
The most striking feature is the position of the metal bead. It is not in the front as with most micrometeorites, but in the middle, which indicates rapid spin during atmospheric entry.
This feature is extraordinarily rare, especially among barred olivine micrometeorites, so it brings me great joy to share this epic micrometeorite with you today. I hope you enjoy this new photo by Jan Braly Kihle and me.
