BAE SYSTEMS MICROPROCESSOR GUIDES ROVER LANDINGS ON MARS
BAE Systems-built “brains†are guiding “Spirit†and “Opportunity†- Mars Rovers that successfully landed in January to explore the Red Planet. Both Rovers are outfitted with BAE Systems radiation-hardened RAD6000 computers. The RAD6000 processed key navigational data during each spacecraft’s six-month journey.

“We are proud to be part of the NASA’s Jet Propulsion Laboratory (JPL) Rover program,†said Vic Scuderi, manager, space products, BAE Systems Information and Electronic Warfare Systems (IEWS) unit. “This has been a tremendous team effort and we are honoured that JPL selected the RAD6000 as their single spacecraft computer on-board the Rovers.â€

The Rovers are designed to study minerals in rocks. They will travel up to 132 feet each day and operate at temperatures as low as minus100 degrees Celsius at night.

The RAD6000 is a high-performance 32-bit Reduced Instruction Set Computer (RISC) that operates in the heavily radiated space environment and is based on the IBM PowerPC architecture. The RAD6000 is one of a family of radiation-hardened protected computers developed and produced by BAE Systems with the support of NASA's JPL and the U.S. Air Force Research Laboratory.

Since 1995, IEWS’ facility in Manassas, Virginia, has delivered more than 300 radiation-hardened computers that have been launched and are operating in space. The RAD6000 was also the single control and data computer used on the successful Pathfinder mission, which landed on Mars in 1997.

i am sorry about the fact that this is old news the rovers are practically danceing on mars surface rite now but i thought it might be interesting to know something about this Processor. can radiation realy affect Microprocessors ? and by useing some kind of material in the caseing of the microchip could that prevent damage of the microchip.?

Radiation is one of the reasons why satellites degrade over time. The shielding breaks down, then so do the systems.

It then becomes orbiting junk

(Hence high value sats are/can and have been retrieved by flying recovery trucks like the space shuttle)

its interesting i am no hardware engineer but the replacement of the microprocessor on the hubble tele was that a repair replacemnet or upgrade i dout it was an upgrade as many said it was i think it was a replacemnt operation replaceing the main circuit would be costly and impracticle given that it was desinged in the rise of space age they may not of counted in the designs for orbital upgrades. is a INTEL 486 microprocessor seam like an upgrade, they argued that it would be a huge improvement in the telescope but i suspect its a repair replacement rather than and upgrade.
