If you think all of that sounds a bit hyperbolic, consider what happened to Hiroshima and Nagasaki. A micrometeoroid is a particle smaller than a grain of sand. Share on Facebook. Julien Rojas, a doctoral student at the University of ParisSaclay and lead author of the study, notes that snowfall at Dome C has quite low accumulation rate, but its enough to shield and preserve the particles. The resulting thinness of each years layer of snow, Rojas says, allowed the team to collect decades of annual micrometeorite deposits in one location without having to melt huge amounts of ice. Falling space dust probably added a sizable contingent of the total amount of volatiles to the Earths surface: water, carbon and other materials that were important for prebiotic chemistry and for the rise of life, he adds. But few events actually yield meteorites: only five or six space stones weighing at least 1kg will hit an area the size of Texas each year.
