Engineers are preparing the JamesWebbSpaceTelescope for operations this summer, including readying the telescope's four science instruments.
While engineers for the James Webb Space Telescope continue the long and delicate process of aligning its mirrors in order to get the telescope ready for science operations this summer, other teams are working on preparing the telescope’s four science instruments for operations. One of the instruments, the Near-Infrared Spectrograph , recently hit a milestone when it completed initial check-outs for three of its mechanisms.
To make sure only light within the wavelengths being investigated gets to the instrument, NIRSpec uses filters to block out unwanted wavelengths, and these filters are controlled by the FWA. To focus the light, the instrument uses the RMA. And the light is separated into a spectrum using gratings, a prism, and a mirror in the GWA.
