This week on SPEXcast, we discuss the Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer (or SPHEREx). It is a two year science mission designed to survey the cosmos in 96 color bands, mapping the whole sky once every 6 months, and all this data will be publicly available. The mission was recently selected by NASA’s Explorer program and is targeting a 2023 launch. Today on the show we are speaking with Dr. Michael Zemcov of the Rochester Institute of Technology. Dr. Zemcov is an assistant professor at the RIT Center for Detectors and one of 19 co-investigators for the SPHEREx mission.
