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).{{cite book|title=57.3.2 Synova Inc Mongoose V|date=19 December 2017|publisher=Extreme Environment Electronics|isbn=9781439874318|pages=660–661|url=https://books.google.com/books?id=-gLSBQAAQBAJ&pg=PA661}}

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[http://pluto.jhuapl.edu/Mission/Spacecraft/Systems-and-Components.php A 3D model of NASA's New Horizons, a mission to Pluto and the Kuiper Belt.], pluto.jhuapl.edu (Website by The Johns Hopkins University Applied Physics Laboratory, access-date: November 4, 2022)
