11:00 am Ariel Cukierman Caltech SPHEREx: An All-Sky Spectral Survey
Abstract: I will present SPHEREx, a NASA mission to map the entire sky with near-infrared spectroscopy. With a targeted launch date in early 2025, SPHEREx has broad scientific reach including 1) cosmic inflation through the three-dimensional distribution of galaxies, 2) the formation of galaxies and the history of light production through deep maps of large-scale clustering and 3) the origin of water in planetary systems by mapping ice absorption in the Milky Way. I will describe the instrument, the survey plan and the expected science return. I will also discuss additional science cases that can be pursued with the legacy archive that will be made available to the community. For the SwRI audience, I will also emphasize SPHEREx's capabilities regarding Solar System science, including asteroid spectroscopy and planetary defense.
