As a NASA photographer, Chris Gunn has been documenting the James Webb Space Telescope (JWST) from its early days. Since 2009 he has captured every milestone and witnessed nearly all the pieces of the spacecraft being put together and tested. The telescope is scheduled to reach space in December, and in the months that follow it will open its 6.5-meter-diameter eye on the sky. At this point, the subject of Gunn’s photography will become a photographer itself. “Seeing those first-light images is what’s most important to me,” Gunn says.
