The March issue of Astronomy and Astrophysics (vol. 683, Mar. 24) is a little light. Two small-body articles are roughly typical of that journal.

I’ll comment that olivine is an open issue within asteroids (and comets- see Stardust). The ‘missing dunite problem’ has been a head-scratcher for… how many decades now? In brief: we have iron meteorites, and iron (M-type) asteroids. These “space cannonballs” formed by being the cores of planetismals that differentiated (melted and self-segregated) in the early Solar System when everything was hot. But if these are the cores, where are all the mantles? The bigger part of a differentiated body? Given the number of iron meteorites and asteroids, there should be an even bigger population of differentiated, olivine-rich (i. e., dunite) meteorites and asteroids, but we don’t see them. Until now (to an extent).
