A selfie taken by Curiosity Mars Rover\'s mast camera and compressed for transmission by the JPEG core available from CAST Woodcliff Lake, New Jersey — CAST, Inc. salesperson Steve Lilly couldn’t have imagined he’d help produce the galaxy’s most prolific selfie-shooting robot when he took that first call from Malin Space Science Systems (MSSS). Yet that’s what ended up happening, as the JPEG Encoder IP Core MSSS licensed from CAST now plays a key role in getting Curiosity Rover’s amazing photos of Mars—and itself—back down to Earth.

The innovative system MSSS designed for the Mars Science Laboratory (MSL) rover uses three imaging systems: the Mars Descent Imager (MARDI) that captured the rover’s landing, the Mars Hand Lens Imager (MAHLI) on the rover’s robotic arm for close-ups of rocks and soil, and the dual-camera Mast Camera (Mastcam) on the rover’s remote sensing mast. These four cameras feed the four-board MMM Digital Electronics Assembly (DEA), a box inside the rover’s temperature-controlled interior that does image processing and JPEG compression and stores the images in 8 Gigabytes of non-volatile NAND Flash memory on each board.[Continue reading →]
