NASA's SPHEREx observatory, photographed in November 2024, has three cones to keep it cool. Highlights NASA's SPHEREx mission will create a 3D map of the universe SPHEREx will study galaxy evolution, cosmic history, and molecules SpaceX Falcon 9 to carry SPHEREx and PUNCH in February 2025 Advertisement An advanced NASA mission to create a three-dimensional map of the sky is set for launch in February 2025. The satellite, named Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer (SPHEREx), will be carried aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California, according to NASA reports. SPHEREx, roughly the size of a compact car, is designed to map millions of stars and galaxies visible from Earth in all directions. Scientists aim to gather unprecedented insights into cosmic events, including the universe's inflation phase following the Big Bang. Primary Goals of the SPHEREx Mission NASA's Jet Propulsion Laboratory (JPL), responsible for SPHEREx's development, has outlined three scientific objectives for the mission, as per sources. The satellite will measure the distribution of hundreds of millions of galaxies to examine the inflation process, believed to have occurred fractions of a second after the Big Bang. By analysing these patterns, researchers hope to uncover new details about the physics governing the universe's early expansion. Another key aspect of the mission involves studying the "collective glow" of distant galaxies, enabling researchers to detect light from previously unobserved galaxies. According to NASA, this data will offer a broader understanding of the universe's structure and energy distribution.
