Astrophysics at Home. Micrometeorites.

Authors: Giuliano Bettini

As stated in P. Rochette et al., "Micrometeorites from the transantarctic mountains", micrometeorites constitute the main part of the flux of extraterrestrial matter accreting on Earth. They are very important to understanding the composition of the solar system. Micrometeorites have been recovered from a variety of terrestrial surfaces (desert, beach sands etc.), showing that their deposition can be evidenced on any surface, provided that the accumulation time is sufficient, and discrimination from terrestrial particles is feasible. I present here my amateur activity of micrometeorite collector in the backyard and in desert sand. Sahara desert sand brought to me by my friend Silvia Calamity.
