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. Short for Specto-Photometer for the History of the universe, Epoch of Reionization, and Ices Explorer, SPHEREx resembles a bullhorn, albeit one that will stand almost 8.5 feet tall (2.6 meters) and stretch nearly 10.5 feet (3.2 meters) wide. Giving the observatory its distinctive shape are its cone-shaped photon shields, which are being assembled in a clean room at NASA’s Jet Propulsion Laboratory in Southern California.
