As Lead of OSIRIS-REx Carbonaceous Meteorites Working Group, Lindsay Keller is responsible for the analysis of carbonaceous meteorite samples that are analogous to the regolith expected on the surface of Bennu.
When the sample return from Bennu in 2023, Keller will investigate the mineralogy and chemistry of the samples at atomic scales using a state-of-the-art transmission electron microscope.
The priority science goals of this study include investigating the effect of solar radiation on asteroidal surfaces, the geological history of the asteroid and the nature and origin of the first solar system solids.
As Lead of OSIRIS-REx Sample Curation, Co-I Kevin Righter is responsible to define curation-related issues for the mission including contamination control and knowledge.
This includes the Sample Return Capsule recovery at the drop site Utah Test and Training Range (UTTR) in Utah, UTTR and ARES cleanroom construction.
Kevin will also establish procedures for sample handling and distribution, sample documentation (imaging, catalog database development etc), and long-term curation planning to ensure the integrity of the collected samples.
As Lead of OSIRIS-REx Sample Site Science Working Group, Co-I Keiko Nakamura-Messenger is responsible for defining the strategy for selecting and characterizing the primary sampling site on Asteroid Bennu based on production and interpretation of the sample value maps. Nakamura-Messenger is also the deputy curation lead of OSIRIS-REx.
Collaborator Aaron Burton is manager of microscale soluble organic analysis instrument facility.
Collaborator Simon Clemett is manager of a unique laser-organic mass spectrometer he designed and built.
Collaborator Kathie Thomas-Keprta is leading the analysis of contamination knowledge surfaces for OSIRIS-REx spacecraft construction.
Collaborator Ann Nguyen performs the NanoSIMS isotope imaging analysis on OSIRIS-REx returned samples. She will characterize presolar grains and organics, as well as early solar system materials found in the asteroid samples.
