Mongoose-V

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

The Mongoose-V processor first flew on NASA's Earth Observing-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 data recorder.

The Mongoose-V requires 5 volts and is packaged into a 256-pin ceramic quad flatpack (CQFP).^[1]

Examples of spacecraft that use the Mongoose-V include:

Earth Observing-1 (EO-1)
NASA's Microwave Anisotropy Probe (MAP), launched in June 2001, carried a Mongoose-V flight computer similar to that on EO-1.
NASA's Space Technology 5 series of microsatellites
CONTOUR
TIMED
Pluto probe New Horizons^[2]
