Allende, Mexico, *1969
Allende is a remarkable meteorite. It fell in Mexico at the peak of the moonshot frenzy, and was analysed by NASA as a dry run for analysing material being brought back from the moon by the Apollo missions.
Allende is a carbonaceous chondrite – rich in carbon-based chemicals and compounds. It contains some of the oldest material known, believed to be left over from the formation of the solar system.
Of the 2 tonnes which fell over Chihuahua that day, the above is a nice 5g collection specimen.
