Detection of Molecular H2O on Nominally Anhydrous Asteroids

We used the FORCAST instrument on SOFIA to obtain mid-infrared spectra (4.9–13.7 μ m) of four S-type asteroids: (7) Iris, (11) Parthenope, (18) Melpomene, and (20) Massalia. Three of these four silicate-rich asteroids (Iris, Melpomene, and Massalia) were observed to have 3 μ m features indicative of...
