JWST's Integrated Science Instrument Module mounted on a test frame
The James Webb Space Telescope's (JWST) Integrated Science Instrument Module (ISIM) can be seen as the black composite framework in this image. The gold-coloured frame under it is the test frame.
The silver-wrapped instrument on the left is the European-provided MIRI (Mid InfraRed Instrument). The gold-coloured instrument, partly visible inside the frame, is the Canadian-provided FGS/NIRISS (Fine Guidance Sensor/Near Infrared Imager and Slitless Spectrograph).
This image was taken while the ISIM was still inside the NASA Goddard Space Flight Center's Space Systems Development and Integration Facility (SSDIF) cleanroom.
