JWST Science Instrument Payload Update

The JWST science instrument payload is designed as a highly integrated module in which many systems are shared among the science instruments in order to reduce mass, power, and volume resources. This Integrated Science Instrument Module (ISIM) system is a 1.4 metric ton element of the JWST space vehicle that consists of four science instruments, a fine guidance sensor (FGS), 7 other shared hardware systems and two shared software systems.
