Launched in July 2020, NASA’s Mars 2020 mission made its final descent to the Red Planet and successfully landed on Jezero Crater on February 18th. Perseverance used a guided entry, descent, and landing system already demonstrated for the Curiosity rover. For this critical step of the mission, NASA added new entry, descent, and landing technologies, such as Terrain-Relative Navigation (TRN), a system allowing the rover to detect and avoid hazardous terrain by diverting around it during its descent through the Martian atmosphere.
Perseverance integrates numerous 3D PLUS’s highly reliable components such as volatile and non-volatile memory modules (SRAM, SDRAM, NAND Flash, NOR Flash, and DDR2), Latch-up Current Limiters, Interfaces, as well as our unique CMOS space-qualified camera head. Embedded in multiple instruments of the rover, 3D PLUS products offer high reliability, radiation tolerance, and weight-saving thanks to our unique stacking technology that allows a high level of miniaturization.
The unique 3D PLUS space-qualified CMOS camera head is embedded inside the SuperCam instrument. It is used as a Micro-Imager, assisting in the selection and targeting of the rocks to be analyzed by the Raman Spectrometer. Result of an R&D project supported by CNES, the French Space Agency, this camera module integrates all the electronic functions of a complete imaging system including memories, processor, power supply, and a 4 Mpx high-resolution CMOS sensor providing color images. With a design based on the 3D stacking technology, this camera module features ultra-compact packaging (35 x 35 x 23 mm, 64 g).
Perseverance will spend at least one Mars year (two Earth years) exploring the landing site region. The rover will seek for signs of ancient microbial life and collect rocks and soil samples for a possible return to Earth. This is also the opportunity for NASA to pave the way for future human exploration missions to the Moon and Mars.
