IR HiRel, a subsidiary of Infineon, helps NASA’s Perseverance rover reach new milestone

[Munich, Germany and El Segundo, Calif., August 5, 2020]NASA’s Jet Propulsion Laboratory launched the Perseverance rover into space on July 30. , to start the Mars exploration journey. The rover is expected to land on Mars in February 2021. IR HiRel, a company of Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY), ​​supplied thousands of Rad Hard key components for the rover. This is the fifth time the company’s power electronics components have been aboard NASA’s Mars rover. IR HiRel has provided power electronics components for Sojourner in 1997, Opportunity and Spirit in 2004, and Curiosity in 2012.

Eric Toulouse, vice president and general manager of IR HiRel, said: “IR HiRel is proud to have provided high-reliability power conversion solutions for space programs for decades. Another important milestone in the history of exploration. We are delighted to have advanced semiconductor technology to help realize this spacecraft program.”

The rover is equipped with multiple subsystems, including: flight computer, motor control, radar, and instrumentation suite for the detection mission. It integrates IR HiRel’s aerospace-grade MOSFETs, ICs and other power control products to ensure that the system can operate in the harsh space of space. Reliable operation in the environment.

Equipped with a groundbreaking suite of scientific instruments, Perseverance can test new technologies in the harsh Martian environment and conduct cutting-edge research to see if Mars was habitable in ancient times, and if there were signs of microbial life. IR HiRel semiconductor specific instruments built into the rover include:

Mastcam-Z: mast-mounted high-definition camera system with panoramic, stereoscopic and zoom capabilities;

SuperCam: equipped with cameras, lasers and spectrometers to search for organic compounds that may be associated with ancient life on Mars;

Planetary X-ray Petrochemical X-ray (PIXL): used to look for signs of past Martian microbes;

SHERLOC Instrument (SHERLOC): This is an ultraviolet light spectrometer that can accurately detect minerals, organic molecules and possible biological signs;

The Martian Oxygen In Situ Resource Utilization Experiment (MOXIE): aims to convert carbon dioxide in the Martian atmosphere into oxygen.

Infineon and its IR HiRel company offer a unique portfolio of highly reliable, radiation-hardened power conversion and RF solutions for space and other harsh environments. Among them, the flight-proven HiRel products are widely used in the Electronic systems of spacecraft.
