ANGSA In Action


Next Gen sample analysis by a Next Gen researcher​
Michael Cato Department of Earth and Planetary Sciences at the University of New Mexico processing bulk regolith samples for hydrogen isotope analyses in a nitrogen glove box to eliminate H2O terrestrial contamination (L). Processing 73002 samples from one of the 0.5 cm core segments for grain size analysis and mineralogy. These data will provide insights into the structure and dynamics of the first lunar landslide deposit sampled and volatile element distribution and behavior in lunar regolith and surface.

Ryan Zeigler at NASA Johnson Space Center conducting X-ray Computed Tomography analysis of lithic fragments separated from the 73002 core. These 3-D images of samples allow development of sampling strategies for a more efficient use of samples and gives the ANGSA science team initial insights into the nature of these fragments.
