The RAD750 will be the most powerful radiation hardened microprocessor ever developed, with 10 times the performance of the current generation processors.

RAD750 performance is expected to be 250-300 millions of instructions per second (MIPS) over the Mil-Spec temperature range.

RAD750 is architecturally and functionally identical as well as pin compatible to the PowerPC 750.

A low risk development approach is being used, leveraging the original PowerPC 750 database for design and verification. The RAD750 will be fabricated in a 0.25 micron CMOS process and include proprietary radiation hardened circuit designs.

Based on early test site hardware, first pass parts will achieve Single Event Upset (SEU) hardness levels of 1E-11 upsets/bit-day (approx. 1E-5 upsets/processor-day) and Total Dose of greater than 200Krads (Si).

Prototype hardware is expected mid-2000, with production availability by year-end.

MSSS Completes Hi-Res Clementine Maps
Washington - July 25, 1999 -
Malin Space Science Systems (MSSS) of San Diego, CA, has completed a set of high-resolution digital maps of the Moon produced from images taken by the US Department of Defense and NASA Clementine Mission in 1994. These maps, which were assembled from several hundred thousand separate Clementine High Resolution (HiRes) camera images, have been delivered to NASA for distribution through the Planetary Data System.
