Modular Unified Space Technology Avionics for Next Generation (MUSTANG), also known as MMS Derived Avionics (MDA), was developed using GSFC internal funds and funds from the Goddard Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission. It is baselined for PACE, the Goddard Ocean Color Instrument (OCI), the Goddard Global Ecosystem Dynamics Investigation (GEDI) Power Controller Unit, and the JPL Multi-Angle Imager for Aerosols (MAIA) Instrument Electronics. The designs, although not the form factor, for the processor, comm card, low voltage power supply, power monitor card, solar array module, segment module, heater module, and engine valve driver have been adopted by the WFIRST project. The Goddard team has worked closely with key Goddard contractors, such as Genesis Engineering, who supported the design and manufacture of a number the MUSTANG cards.
