SPHEREx is NASA’s upcoming astrophysics medium-class explorer mission (MIDEX), set to launch in early 2025. It will conduct the first all-sky spectral survey across the 0.75 to 5µm wavelength range, achieving a spectral resolution of R~40 from 0.75 to 3.8µm, and R~120 from 3.8 to 5µm. Optimized to map the Universe’s large-scale structure, SPHEREx will also produce deep maps of the diffuse extragalactic background light at the ecliptic poles, while providing spectra for millions of Milky Way sources and hundreds of millions of galaxies.
In this talk, I will outline the primary science objectives of SPHEREx and explore the potential for cross-collaboration with other external experiments. As we approach the mission’s launch, I will also share details on the instrument design and present initial performance results from laboratory calibrations.
