Test Chamber for NASA’s New Cosmic Mapmaker Makes Dramatic Entrance
The customized test chamber for the SPHEREx mission has 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). Courtesy NASA/JPL-Caltech.
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).
