Mongoose-V is a radiation-resistant 32-bit microprocessor for on-board computer systems of spacecraft. It is an extended version of the MIPS R3000 microprocessor, manufactured with measures to protect against radiation effects. It operates at a frequency of 10-15 MHz , developed in 1998 by Synova, Inc. ( Melbourne , USA ) with the support of NASA's Goddard Space Flight Center .

Mongoose-V processors were first used on NASA's Earth Observing-1 (EO-1) spacecraft, launched in November 2000. One of them functioned as the main on - board computer , the second Mongoose-V controlled the satellite's solid state recorder .
Processor case - 256-pin ceramic (CQFP), supply voltage - 5 Volts [1]
Spacecraft using Mongoose-V:
- Earth Observing-1 (EO-1)
- The Microwave Anisotropy Probe (MAP) probe, launched in June 2001, used a Mongoose-V-based on-board computer, similar to the EO-1.
- NASA Space Technology 5 Microsatellite Series
- CONTOUR
- TIMED
- Spacecraft " New Horizons " [2]
In 2012, the processor cost was about 20-40 thousand US dollars [3] .
