The future of space exploration looks to grow even brighter as the launch of NASA’s highly anticipated SPHEREx mission lies right on the horizon. The mission, set to launch the evening of March 7, 2025 will survey the vast expanse of space for the next two years to construct an unprecedented map of the sky.

NASA is ready to tackle the universe’s most pressing questions with Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx). Launching on a SpaceX Falcon 9 rocket out of the Vandenberg Space Force Base in California, the telescope will not only chronicle the history of the universe by identifying galaxies billions of light years away from Earth, but it will also carry out an important search closer to home as it combs through the Milky Way for signs of water and organic molecules.
