![]() Research from the AEMC on comet dust was recently featured in the Proceedings of the National Academy of Sciences ( Ishii et al. Students explored their own samples using FIB-SEM and TEM during the lab sections. 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. ![]() They will also explore whether oxidation has occurred on Earth in other Apollo samples that were not stored in the same manner. ![]() 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. Cernan.ĪEMC’s former 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. Specialized sample holders allow temperature control to mimic warmer temperatures of sunlit regions and cryogenic temperatures in permanently shadowed regions of the Moon where water can accumulate.Īpollo 17 (1972) scientist-astronaut Harrison H. The effects of interactions between volatiles and lunar soil as well as simulants will be studied at nanometer-length scales using the AEMC Titan transmission electron microscope. They are members of the Interdisciplinary Consortium for Evaluating Volatile Origins, or ICE Five-O, one of eight teams selected last summer by NASA’s Solar System Exploration Research Virtual Institute.

The floor of this crater is permanently shadowed from sunlight. Image taken by the Lunar Reconnaissance Orbiter Camera of part of the rim of Shackleton crater near the lunar South Pole.
