Months after arriving in orbit thanks to a Falcon 9 rocket launch from Vandenberg Space Force Base, NASA’s newest space telescope has started collecting images of the universe. The craft known as SPHEREx — Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer — shared a ride with another NASA mission for the trek on March 11.
The SPHEREx mission will observe the entire sky multiple times over its planned two-year mission. It employs Linear-Variable Filter (LVF) technology to capture spectra across 100 spectral bands in the near-infrared spectrum. The mission focuses on exploring the origins of the universe, galaxies, water, and pre-biotic molecules, with a deep survey near the ecliptic poles and an all-sky survey during its mission. SPHEREx aims to achieve deeper sensitivities than 2MASS and meet scientific requirements with margins over instrument performance.
NASA's SPHEREx mission aims to study the origins of the universe, the history of galaxies, and the presence of water and pre-biotic molecules in planetary systems. It will conduct an all-sky spectral survey to gather data on over 100 million stars and galaxies, providing insights into large-scale cosmic structures and the history of galaxy formation.
