SPHEREx — Surveys the sky with spectroscopy to study cosmic history and interstellar ices.

Mission and scientific objectives
SPHEREx is associated with NASA / Jet Propulsion Laboratory. Surveys the sky with spectroscopy to study cosmic history and interstellar ices. The mission type is Infrared space observatory.

Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer

The Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx) mission will provide an all-sky spectral survey. Over a two-year planned mission, the SPHEREx Observatory will collect data on more than 450 million galaxies along with more than 100 million stars in the Milky Way in order to explore the origins of the universe.
