Journey of the Mirrors

A Cross-Country Journey of Mirror Making

The James Webb Space Telescope's 18 special lightweight beryllium mirrors have to make 14 stops to 11 different places around the U.S. to complete their manufacturing. The 18 mirror segments will form the Webb telescope's huge primary mirror. There are 18 segments, because it takes a large mirror to look back farther back in time. They come to life at beryllium mines in Utah, and then move across the country for processing and polishing. In fact, the mirrors make stops in eight states along the way, visiting some states more than once, before journeying to South America for lift-off and the beginning of their final journey to space. This graphic shows the different places they have to travel, and what is accomplished at each location. Just move your mouse over the number!
