ARES Scott R Messenger


Scott Messenger is a planetary scientist within the Astromaterials Research and Exploration Science (ARES) Division at the Johnson Space Center. Messenger's expertise is in isotopic analyses of extraterrestrial materials by secondary ion mass spectrometry (SIMS). His research interests include the nature and origin of materials in the solar nebula and preserved interstellar matter and stardust from comets and meteorites. While in graduate school, Messenger's work focused on isotopic analyses of molecular cloud materials and stardust extracted from meteorites and interplanetary dust particles. Before coming to Johnson, he was a National Research Council Fellow at the National Institute for Standards and Technology from 1997 to 1999, where he developed techniques for isotopic measurements by time-of-flight SIMS. He subsequently rejoined his graduate research group at Washington University where he worked with the first NanoSIMS ion microprobe. Currently, Messenger works to coordinate isotopic studies with mineralogical studies by transmission electron microscopy and organic analyses by resonance ionization mass spectrometry and other spectroscopic techniques. He also took part in the analysis of cometary dust returned by the Stardust spacecraft in 2006.
