Highlights from the March 11, 2025, launch of NASA’s SPHEREx space telescope, which will observe hundreds of millions of galaxies, mapping the entire sky in 102 wavelengths that are invisible to the human eye. The spacecraft lifted off from Vandenberg Space Force Base in California at 8:10 p.m. PDT.
SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) will orbit Earth for a two-year prime mission and create a 3D map of the cosmos. This will help scientists answer major questions about what happened in the first second after the big bang, how galaxies form and evolve, and the origins and abundance of water and other key ingredients for life in our galaxy.
Ride-sharing with SPHEREx was NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission, which will study the outer portion of the Sun, the corona, to understand how solar wind forms.
