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
. 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 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.
Examples of spacecraft that use the Mongoose-V include:
32-bit
The range of integer values that can be stored in 32 bits is 0 through 4,294,967,295. Hence, a processor with 32-bit memory addresses can directly access 4 GB of byte-addressable memory....

The R3000 is a microprocessor chip set developed by MIPS Computer Systems that implemented the MIPS I instruction set architecture . Introduced in June 1988, it was the second MIPS implementation, succeeding the R2000 as the flagship MIPS microprocessor...
CPU
Central processing unit
The central processing unit is the portion of a computer system that carries out the instructions of a computer program, to perform the basic arithmetical, logical, and input/output operations of the system. The CPU plays a role somewhat analogous to the brain in the computer. The term has been in...

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 5Space Technology 5Space Technology 5 of the NASA New Millennium program is a test of ten new technologies aboard a group of microsatellites. Developed by NASA Goddard Space Flight Center, the three small spacecraft were launched separately from the belly of an Lockheed L-1011 aboard the Pegasus XL rocket, on 22...
