The SPHEREx Concept Study Report Submitted to NASA

NASA and SpaceX are targeting late February 2025 for the launch of the agency’s next astrophysics observatory, SPHEREx. Short for Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer, SPHEREx will launch aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California.

SPHEREx Observatory is back in the BAE cleanroom for final cleaning, testing and closeouts prior to shipment to the launch site.

The space telescope will detect over 100 colors from hundreds of millions of stars and galaxies. Here’s what astronomers will do with all that color.

SPHEREx observatory continues its thorough testing campaign and successfully passed its vibe test at BAE Systems in Boulder, CO.
