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 at Caltech’s Cahill Center for Astronomy and Astrophysics in Pasadena. About the size of a small SUV and made of stainless steel, the cylindrical chamber was built by the Korean Astronomy and Space Science Institute (KASI), a partner in the SPHEREx mission. It will be used to test SPHEREx’s detectors (essentially its cameras) and optics (the system that collects light from the cosmos).
