ESA and Airbus engineers watch the real time strain gauge data while the Near InfraRed Spectrograph (NIRSpec) is being mated to the Integrated Science Instrument Module (ISIM). This data indicate whether the NIRSpec kinematic mount stress levels are within acceptable limits.

NIRSpec is one of four instruments on JWST. It is a multi-object spectrograph capable of observing at least 100 astronomical objects simultaneously. It will support JWST's four main science themes by providing low, medium and high-resolution spectroscopic observations.

NIRSpec is developed by ESA with Airbus Defence and Space, Germany, as the prime contractor. NIRSpec's Micro Shutter Assembly (MSA) and Focal Plane Assembly (FPA) are provided by NASA.
