Dante Lauretta's research interests focus on the origin and chemical evolution of the solar system. His main focus is the formation and alteration of minerals in the solar nebula and on meteorite parent asteroids. He is also working on the application of inductively coupled plasma-mass spectrometry to geologic studies. In addition, he is studying the extent of Hg isotopic fractionation in natural systems. This project represents a potentially new stable isotope system with applications in meteoritics, geology, biogeochemistry, and environmental studies.
Spacecraft OSIRIS REx is now orbiting a 260-meter asteroid named Bennu. Principal investigator Dante Lauretta returns to tell us what has already been learned, and to preview the excitement that is still to come, including the probe’s descent to the surface for collection of a pristine sample.
The OSIRIS-REx instrument team has successfully installed the Regolith X-ray Imaging Spectrometer (REXIS) on the spacecraft. However, there is more to the story of how REXIS made it onto the spacecraft.
The OSIRIS-REx team successfully and safely completed sine vibration (sine vibe) testing on the spacecraft prior to the Thanksgiving holiday. The sine vibe tests are designed to verify the system performs as expected after being exposed to flight-like low frequency vibration input.
