Mongoose-V
The Mongoose-V 32-bit microprocessor for spacecraft onboard computer applications is a radiation hardening, radiation-hardened and expanded 10–15 megahertz, MHz version of the MIPS architecture, MIPS R3000 central processing unit, CPU. Mongoose-V was developed by Synova of Melbourne, Florida, Melbourne, Florida, United States, 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). Examples of spacecraft that use the Mongoose-V include: * Earth Observing-1 (EO-1) * NASA's Microwave Anisotropy Probe (WMAP, MAP), launched in June 2001, carried a Mongoose-V flight computer similar to that on EO-1. * NASA's Space Technology 5 series of Microsatellite (space ...

Space Technology 5
Space Technology 5 (ST5) of the NASA New Millennium program was a test of ten new technologies aboard a group of microsatellites. Developed by NASA Goddard Space Flight Center, the three individual small spacecraft were launched together from the belly of a Lockheed L-1011 aboard the Pegasus XL rocket, on 22 March 2006. One technology involved antennas that were designed by computers using an evolutionary AI system developed at NASA Ames Research Center. The ST5 on-board flight computer, the C&DH (Command & Data Handling) system, was based on a Mongoose-V radiation-hardened microprocessor. On 30 June 2006 the satellites making up ST5 were shut down after successfully completing their technology validation mission. Mission objectives ST5's objective was to demonstrate and flight qualify several innovative technologies and concepts for application to future space missions. ; Communications Components for Small Spacecraft: The X-Band Transponder Communications System w ...

Radiation Hardening
Radiation hardening is the process of making electronic components and circuits resistant to damage or malfunction caused by high levels of ionizing radiation ( particle radiation and high-energy electromagnetic radiation), especially for environments in outer space (especially beyond the low Earth orbit), around nuclear reactors and particle accelerators, or during nuclear accidents or nuclear warfare. Most semiconductor electronic components are susceptible to radiation damage, and radiation-hardened (rad-hard) components are based on their non-hardened equivalents, with some design and manufacturing variations that reduce the susceptibility to radiation damage. Due to the extensive development and testing required to produce a radiation-tolerant design of a microelectronic chip, the technology of radiation-hardened chips tends to lag behind the most recent developments. Radiation-hardened products are typically tested to one or more resultant-effects tests, including tot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
R3000
The R3000 is a 32-bit RISC microprocessor chipset developed by MIPS Computer Systems that implemented the MIPS I instruction set architecture (ISA). Introduced in June 1988, it was the second MIPS implementation, succeeding the R2000 as the flagship MIPS microprocessor. It operated at 20, 25 and 33.33 MHz. The MIPS 1 instruction set is small compared to those of the contemporary 80x86 and 680x0 architectures, encoding only more commonly used operations and supporting few addressing modes. Combined with its fixed instruction length and only three different types of instruction formats, this simplified instruction decoding and processing. It employed a 5-stage instruction pipeline, enabling execution at a rate approaching one instruction per cycle, unusual for its time. This MIPS generation supports up to four co-processors. In addition to the CPU core, the R3000 microprocessor includes a Control Processor (CP), which contains a Translation Lookaside Buffer and a Memory Mana ...

New Horizons
''New Horizons'' is an interplanetary space probe that was launched as a part of NASA's New Frontiers program. Engineered by the Johns Hopkins University Applied Physics Laboratory (APL) and the Southwest Research Institute (SwRI), with a team led by Alan Stern, the spacecraft was launched in 2006 with the primary mission to perform a flyby study of the Pluto system in 2015, and a secondary mission to fly by and study one or more other Kuiper belt objects (KBOs) in the decade to follow, which became a mission to 486958 Arrokoth. It is the fifth space probe to achieve the escape velocity needed to leave the Solar System. On January 19, 2006, ''New Horizons'' was launched from Cape Canaveral Space Force Station by an Atlas V rocket directly into an Earth-and-solar escape trajectory with a speed of about . It was the fastest (average speed with respect to Earth) man-made object ever launched from Earth. It is not the fastest speed recorded for a spacecraft, which as of 2021 ...

Vanderbilt University
Vanderbilt University (informally Vandy or VU) is a private research university in Nashville, Tennessee. Founded in 1873, it was named in honor of shipping and rail magnate Cornelius Vanderbilt, who provided the school its initial $1-million endowment in the hopes that his gift and the greater work of the university would help to heal the sectional wounds inflicted by the Civil War. Vanderbilt enrolls approximately 13,800 students from the US and over 100 foreign countries. Vanderbilt is classified among "R1: Doctoral Universities – Very high research activity". Several research centers and institutes are affiliated with the university, including the Robert Penn Warren Center for the Humanities, the Freedom Forum First Amendment Center, and Dyer Observatory. Vanderbilt University Medical Center, formerly part of the university, became a separate institution in 2016.

Faraday Cage
A Faraday cage or Faraday shield is an enclosure used to block electromagnetic fields. A Faraday shield may be formed by a continuous covering of conductive material, or in the case of a Faraday cage, by a mesh of such materials. Faraday cages are named after scientist Michael Faraday, who invented them in 1836. A Faraday cage operates because an external electrical field causes the electric charges within the cage's conducting material to be distributed so that they cancel the field's effect in the cage's interior. This phenomenon is used to protect sensitive electronic equipment (for example RF receivers) from external radio frequency interference (RFI) often during testing or alignment of the device. They are also used to protect people and equipment against actual electric currents such as lightning strikes and electrostatic discharges, since the enclosing cage conducts current around the outside of the enclosed space and none passes through the interior. Faraday cages ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
