SPHEREx is slated to launch Feb. 27 on a SpaceX rocket. It is meant to map the entire night sky in infrared — something even the JWST can't exactly do.

NASA’s SPHEREx observatory separates from a SpaceX Falcon 9 second stage after launching from Space Launch Complex 4 East from Vandenberg Space Force Base in California on Tuesday, March 11.

NASA has just offered an update on its ambitious SPHEREx mission, which plans to map the entire sky from low-Earth orbit when it launches in the next couple of years. Short for Spectro-Photometer ...

“SPHEREx is an all-sky survey in the near-infrared. So we’re going to orbit around Earth about 400 miles up -- and instead of looking down at Earth, we’re looking out at space,” said Rocca.

"SPHEREx is really trying to get at the origins of the universe - what happened in those very few first instants after the Big Bang," SPHEREx instrument scientist Phil Korngut of Caltech said.

NASA’s SPHEREx mission, which launched in March 2025, is poised to transform our understanding of the universe. By creating an all-sky map of the cosmos in 102 different infrared wavelengths ...

NASA’s latest infrared space telescope, SPHEREx —short for Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer—will assemble the world’s most ...

SPHEREx mission seeks answers to cosmic mysteries What happened a fraction of a second after the big bang? That's one of the questions scientists hope to unravel through the SPHEREx mission.

Instead, SPHEREx is a type of mission called a survey telescope, which looks at the entire sky. That enables it to see information about the universe on a large scale.

SPHEREx's filters are designed to block all but one wavelength from reaching the telescope. (Image credit: NASA/JPL-Caltech) Some, however, may think this telescope looks a bit odd.

SPHEREx a $242 million pursuit that will launch in 2023. For two years, the shuttlecock-shaped observatory will circle Earth in an orbit twice as a high as the International Space Station.
