CosmoELEMENTS keeps us in touch with exciting discoveries in cosmochemistry and provides short articles that can be used in the classroom or report on the space missions carrying geochemical and mineralogical instruments.
Proposals for future articles are welcome and should be sent to the Elements Executive Editor, or to the Column Editor, Cari Corrigan, at firstname.lastname@example.org.

This material, also known as interplanetary dust particles (IDPs), can be collected directly from Earth’s atmosphere. NASA has collected particles in the stratosphere for nearly three decades.Read More

Back before the cosmic origins of meteorites were accepted, it is understandable that any material that fell from the heavens was the subject of some debate; historically, meteoritic material was often viewed as especially rare and valuable, as a gift from the Gods, or even cursed.Read More
