The center section of the "pathfinder" (test) backplane of NASA's James Webb Space Telescope is being used to install Webb's test mirrors. By installing the mirrors on the replica, technicians at Goddard Space Flight Center are able to practice this delicate procedure for when the actual flight backplane arrives. Installation of the mirrors on the backplane requires precision, so practice is important.
