Mongoose-V

From Wikipedia, the free encyclopedia

The Mongoose-V 32-bit microprocessor for spacecraft on-board computer applications is a radiation-hardened and expanded 10–15 MHz version of the MIPS R3000 CPU. The Mongoose was developed by Synova, Inc. of Melbourne, Florida, USA, with support from the NASA Goddard Space Flight Center.

The Mongoose-V processor first flew on NASA's Earth Observer 1 (EO-1) satellite launched in November 2000 where it functioned as the main flight computer. A second Mongoose-V controlled the satellite's solid-state date recorder. NASA's Microwave Anisotropy Probe (MAP), launched in June 2001, carried a Mongoose-V flight computer similar to that on EO-1. An example of spacecraft using the Mongoose-V as part of a flight computer is NASA's Space Technology 5 series of microsatellites and the interstellar probe New Horizons.
