Sena is an ordinary (H4) chondrite that fell November 17, 1773, near Sarinena, Spain.
The meteorite was later analyzed by the French chemist J. L. Proust, who may have been the first to recommend cold deserts, such as polar regions, for meteorite recovery. He determined this in 1805, based on the iron-nickel inclusions in Sena which, he postulated, would rust and degrade in wet climes.
Today, scientists make yearly trips to the Transantarctic Mountain region to recover meteorites, as part of the AnsMet (ANtarctic Search for METeorites) program.
The Center for Meteorite Studies’ Director, Meenakshi Wadhwa, participated in the AnsMet 2012-2013 field season. You can read her blogs from the field, as well as those of other ANSMET team members, here!
