After a successful and on schedule delivery of the payload by the Caltech and JPL SPHEREx team to BAE Systems in Boulder, CO, the final assembly or the SPHEREx spacecraft has began. In the picture below, you can see two of the three SPHEREx photon shields attached. Hidden inside the photon shield and invisible in this picture lie the SPHEREx telescope and instruments. The conic photon shields will protect the telescope from the light and heat of the Sun and Earth.

SPHEREx has made detailed multi-spectral observations of interstellar comet 3I/ATLAS, detecting an abundance of carbon dioxide gas in its coma (the extended gaseous atmosphere of a comet) and water ice in its nucleus. The observations were made between Aug. 7 to Aug. 15, when the object was about 290 million miles (470 million kilometers) from the Sun.
