SPHEREx's Perspective From Orbit (Artist's Concept)

NASA's SPHEREx mission will create the first all-sky spectroscopic survey in the near-infrared, detecting hundreds of millions of stars and galaxies. To do this, the SPHEREx space telescope will look outward from low-Earth orbit, circling the planet along its day-night (or terminator) line. This artist's concept depicts the spacecraft's orbital plane in orange, and its field of view in green. Each of the telescope's orbits allows it to image a 360-degree strip of the celestial sky.
