Phil Korngut tests NASA’s SPHEREx telescope under extreme conditions in the SPHEREx laboratory in California.

The SPHEREx List of ICE Sources (SPLICEs), just published by a team led by CfA astronomers Matthew Ashby and Joseph Hora, presents a catalog of 8.9 million objects of interest for the upcoming SPHEREx Ices investigation.  

Key elements are coming together for NASA’s SPHEREx mission, a space telescope that will create a map of the universe like none before. NASA’s SPHEREx space telescope is beginning to look much like it will when it arrives in Earth orbit and starts mapping the entire sky.

NASA's SPHEREx space telescope has been tucked inside a custom-built chamber on and off for the past two months undergoing tests to prepare it for its two-year mission in space. This news piece describes this testing milestone.

In this timelapse movie, scientists and engineers can be seen preparing NASA’s SPHEREx space telescope for tests inside a vacuum chamber at Caltech that simulates the environment of space.

The SPHEREx team completed the first successful testing of the SPHEREx flight instrument – detector assemblies, telescope, and thermal control system.

SPHEREx team members showcased SPHEREx during the Explore JPL open house.

The SPHEREx mission will create a 3D map of the entire sky. Its cutting-edge instruments require a custom-built chamber to make sure they’ll be ready to operate in space. After three years of design and construction, a monthlong boat ride across the Pacific Ocean, and a lift from a 30-ton crane, the customized test chamber for NASA’s upcoming SPHEREx mission has finally reached its destination...
