AEMC‘s director Hope Ishii and researcher John Bradley are part of a team, one of nine, recently selected by NASA to study Apollo mission samples from the Moon that have never before been opened and exposed to Earth‘s atmosphere. Together with Jeff Gillis-Davis, these HIGP scientists are planning analyses to establish how exposure to space environments alters surfaces of lunar samples and simulants. They will also explore whether oxidation has occurred on Earth in other Apollo samples that were not stored in the same manner.

Postdoctoral Researcher Kenta Ohtaki led lab sections for GG 710 Electron & Ion Microscopy, a new course offered in Spring 2019 to introduce graduate students to the instruments and analytical capabilities in the Advanced Electron Microscopy Center. Students explored their own samples using FIB-SEM and TEM during the lab sections.

Research from the AEMC on comet dust was recently featured in the Proceedings of the National Academy of Sciences (Ishii et al. 2018 PNAS 115 (26) 6608-6613) and received major media attention. The work shows multiple generations of dust aggregation in the earliest stages of planet formation and suggests that glassy grains in comets are interstellar dust that survived solar system formation. The research was covered by Nature, Forbes, and USA Today, among others.

Laura Corley, a graduate student in Geology and Geophysics, completed about 75 hours of on-instrument training to earn her “drivers license” on the Helios 660 FIB. She independently lifts out her own FIB sections and thins them for TEM analysis.

October 2017

The AEMC featured prominently in an article in the Oct/ Nov 2017 issue of Hana Hou!, the print magazine of Hawaiian Airlines. The article, titled “Particles of Interest” highlighted a new collection of extraterrestrial dust at Mauna Loa Observatory and the work going on in the AEMC to locate and analyze particles, especially ones of cometary origin.
