Lunar Dust Grains Are Analyzed Atom-By-Atom To Find Water And Helium
Precious Lunar Samples May Be Analyzed From A Single Grain Of Dust; University Of Chicago Graduate Student Jennika Greer And Colleagues At Field Museum Use Atom Probe Tomography, Which Allows Grains To Be Measured Atom-By-Atom For 3-Dimensional Data From Sample; APT Is Used On Small Grain From Apollo 17 Sample 71501, Separated For Particles 150-200 μm In Diameter; Technique Sees Effects Of Space Weathering And Identifies Water And Helium, Valuable Resources For Future Lunar Settlements
